Free book, AudioBook, Reender Book Surgery: A Case Based Clinical Review by Christian de Virgilio full book,full ebook full Download. The book begins using a case based approach. The cases presented cover the diseases most commonly encountered on a surgical rotation. The cases are designed to provide the reader with the classic findings on history and physical examination. The essential management of the septic patient includes early recognition, fluid resuscitation, blood cultures, broad-­ spectrum IV antibiotics, and vasopressors norepinephrine first; then vasopressin. There is a notable absence of large randomized, controlled trials demonstrating improved survival of adjunctive treatment options aside from the above essentials. Urine output can be a surrogate for targeted fluid resuscitation with a goal of 0. Intensive glycemic control is no ­longer favored as this has been shown to cause more morbidity than maintaining more moderate glycemic control see NICE-SUGAR trial.

For any emergency patient, assess the ABCs: airway, breathing, and circulation. Scan for breathing while firmly tapping and asking the patient to speak to check their airway. Attach the monitor and defibrillator to the patient, and continue chest compressions for 2 min. Then, check for a pulse and determine if the rhythm is shockable pulseless ventricular tachycardia and ventricular fibrillation. If it is, shock the patient and resume chest compressions. After 2 min, recheck the pulse and rhythm and shock again if warranted.

If the patient does not respond after this second cycle of chest compressions and defibrillation, give 1. Continue to recheck pulse and rhythm, shock if warranted, and give epinephrine every 3—5 min. If the patient continues to remain in ventricular tachycardia or ventricular fibrillation, amiodarone may replace epinephrine only for the second dose. If the rhythm is not shockable pulseless electrical activity or asystole , resume chest compressions for 2 min, and administer 1. Continue CPR and epinephrine boluses every 3—5 min until the underlying cause is treated or the rhythm becomes shockable.

Synchronized shock cardioversion is the delivery of a low-­energy shock which synchronizes to the QRS complex. It is used for unstable atrial fibrillation, atrial flutter, and supraventricular tachycardias unresponsive to mediation. Desynchronized shock defibrillation is the delivery of a random high-energy shock as soon as the shock button is pressed irrespective of the QRS complex. It is used when there is uncoordinated intrinsic electrical activity in the heart, such as pulseless ventricular tachycardia or ventricular fibrillation. If patient remains unresponsive after two cycles of defibrillations, continue CPR with epinephrine.

She reports that the lump reappeared a few days ago but she can no longer push it back in. She has had no bowel movement and no flatus per rectum for the past h.

Her temperature is She appears ill and uncomfortable with dry mucous membranes. Lung sounds are clear bilaterally. Her abdomen is mildly distended. Bowel sounds are high pitched with tinkles and rushes. Her abdomen is non-tender to palpation. There is a 2 × 2 cm mass in the left groin inferior to the inguinal ligament that is very painful to palpation. The overlying skin is slightly erythematous. The bulge is just medial to her femoral pulse, extending toward her thigh compartment. Laboratory studies are significant for white blood count of Table 2. The presence of abdominal distention, a groin mass below the inguinal ligament , and high-pitched bowel sounds in a patient with progressive nausea with vomiting is highly suggestive of acute intestinal obstruction from a femoral hernia.

The addition of systemic signs of inflammation or infection fever, tachycardia, leukocytosis and localized pain and redness of the skin overlying the hernia strongly suggests that the bowel within the hernia sac is ischemic or gangrenous. In this setting, emergent surgical intervention is necessary. Most often, a mass in the inguinal region in men and women will represent enlarged lymph nodes. Lymph nodes may enlarge either due to autoimmune disease, malignancy, or as a response to a localized or systemic infection.

Reactive nodes are usually sub-centimeter, mobile, tender, and firm. If nodes are very large, tender, and limited to the inguinal region, one must consider syphilis, chancroid, and lymphogranuloma venereum. Large non-tender inguinal lymphadenopathy limited to the inguinal region suggests metastatic cancer from a local source melanoma, anal, or genital cancer. Large non-tender inguinal lymph nodes associated with diffuse lymphadenopathy suggest a systemic process infectious, malignant, or autoimmune such as tuberculosis, lymphoma, leukemia, HIV, or sarcoidosis. A groin mass that protrudes with straining Valsalva and reduces in the supine position is highly suggestive of a hernia. Acquired hernias develop as a result of structural weakness of the abdominal wall in conjunction with increased intraabdominal pressure. Contributing factors include prior incisions, heredity, constipation, multiple pregnancies, obesity, and liver disease with ascites. History should include conditions that lead to chronic straining, as these may provide clues to underlying untreated conditions such as a chronic cough chronic bronchitis, lung cancer , constipation colon cancer , or urinary straining benign prostatic hypertrophy, prostate cancer.

It is also important to inquire about workand activity-related issues such as heavy lifting and physical exertion. A hernia is a protrusion of tissue or organ s through a defect, most commonly in the abdominal wall. Hernias have three components: the abdominal wall defect, the hernia sac which protrudes through the defect, and the contents within the sac. The neck of a hernia is the part of the hernia sac adjacent to the abdominal wall defect. If the neck is narrow as is the case for most femoral hernias , the bowel herniates less frequently, but once it does enter, it has a higher chance of becoming constricted by the narrow neck and becoming incarcerated.

Between an Incarcerated and a Strangulated One? A hernia can be described as reducible if the contents within the sac can be pushed back through the defect into the peritoneal cavity, whereas with an incarcerated hernia, the contents are stuck in the hernia sac. A strangulated hernia is a type of incarcerated hernia in which there is compromised blood flow to the herniated organ usually the small intestine but can also be the omentum, large bowel, or ovary. Strangulation more frequently occurs when the hernia defect is narrow. A loop of bowel protrudes through the hernia and becomes entrapped by the narrow neck. This may lead to a closed-loop bowel obstruction with both ends of the bowel blocked and nowhere for fluid and gas to egress. As the bowel continues to produce gas and secrete fluid, the progressive distention leads to a compromise of the blood flow.

A strangulated hernia requires prompt surgical intervention as delays lead to worsening sepsis and death. This risk, however, is increased in symptomatic patients and those with significant comorbidities. Predisposing risk factors include older age, duration of hernia shorter is worse , type femoral , and comorbidities. Some hernias particularly those with large defects can be chronically incarcerated and therefore irreducible for years without causing major symptoms e. Others particularly with narrow necks are at higher risk of progressing to strangulation. In general, indirect inguinal hernias are congenital, whereas direct hernias are acquired.

Indirect inguinal hernias are caused by a persistent patent processus vaginalis. During embryologic development, the processus vaginalis, an outpouching of the peritoneum, descends into the scrotum, bringing along the testicle with it. It subsequently closes prior to birth. If the processus remains patent open , peritoneal fluid can fill the scrotum communicating hydrocele , or the bowel can pass through the patent processus vaginalis into the scrotum indirect hernia. In men, the indirect hernia sac travels along with the spermatic cord through the internal ring and into the scrotum. In women, it follows the tract of the round ligament toward the pubic tubercle. They typically manifest after years of chronic straining, causing wear and tear to the abdominal wall musculature. Since they are acquired, it is unusual to find a direct inguinal hernia in a young person.

The neck of an indirect inguinal hernia is relatively narrow as it passes through a relatively rigid and inflexible space the internal ring , whereas direct inguinal hernias typically have a more broad-based neck, making strangulation less likely to occur. Watch Out Indirect inguinal hernias traverse the deep ring and the superficial ring, while direct inguinal hernias only pass through the superficial ring. In children, most are asymptomatic and close spontaneously with no intervention surgery if persists beyond age 4. In adults, umbilical hernias are associated with increased intra-­abdominal pressure pregnancy, ascites, weight gain. Surgery is recommended if symptomatic. Ventral or incisional hernias appear most commonly in the midline or at the site of a previous surgical incision and can occur weeks, months, or even years after the procedure. The lateral border is formed by the inferior epigastric vessels, the medial border by the rectus sheath, and the base by the posterior wall of the inguinal ligament.

Femoral hernias occur in the femoral canal. From: Ates M, et al. Reprinted with permission from Springer Nature Ext. hernia de Laugier Retrovascular hernia Serafini Pectineal hernia Callisen-Cloquet.. It is particularly dangerous because if it is not recognized, the bowel can easily be injured or transected when dividing the hernia sac. An indirect hernia sac should always be opened anteriorly as this will prevent making a hole in the bowel or bladder if a sliding hernia is present. Watch Out A hernia containing the appendix is termed Amyand hernia, while one containing small bowel with a Meckel diverticulum is termed Littre hernia. Remember, Amyand for appendix and Littre for little kids Meckel. From Miller R, et al. Umbilical hernia in babies and children.

In: LeBlanc K, Kingsnorth A, Sanders D, editors. Management of abdominal hernias. Cham: Springer; Bowel entering a femoral hernia passes down the narrow femoral canal. The femoral ring, which serves as the entrance to the femoral canal, is very rigid and unyielding. Thus, the fixed neck of a femoral hernia is prone to pinching off the bowel, putting the patient at risk for incarceration. A hernia below the inguinal ligament indicates that it is a femoral hernia, which passes under posterior to the inguinal ligament. Hernias are considered a clinical diagnosis. A good history of a reducible mass that protrudes with straining and a good physical exam are typically all that is needed. For both men and women, the patient is asked to stand. The patient is asked to Valsalva or cough. If a hernia is present, a bulge will be palpated. Both indirect inguinal hernias and umbilical hernias are common in infants.

The physical exam may be challenging as the infant cannot cough or strain on command. Thus, the history from the parent of a noticeable bulge with crying is important. cumference of the bowel wall is trapped within the hernia sac. Since only part of the wall of the small intestine is herniated, patients do not have signs or symptoms suggestive of bowel obstruction. The absence of obstruction may mislead the clinician into thinking that the bowel is not at risk for strangulation. A sliding hernia is a type of indirect hernia that occurs when a retroperitoneal organ usually colon or bladder typically herniates with the sac and essentially makes up the posterior wall of the sac. It usually occurs in males and more often on the left side. Indirect inguinal hernias travel through the internal ring along with the spermatic cord. Abdominal hernias are typically diagnosed on the basis of a history and physical exam. However, at times, physical exam will be nondiagnostic despite a history that is strongly suggestive of a hernia.

In particular, hernias may be difficult to appreciate in the morbidly obese, due to abundant subcutaneous fat. In these circumstances, adjunctive imaging studies may 2 16 2 A. aid in the diagnosis. Ultrasound with Valsalva is cost-­effective and will often demonstrate an inguinal hernia but has limited efficacy in the obese patient. Cross-sectional imaging including computed tomography CT scan or magnetic resonance imaging MRI may be helpful. CT scan and MRI are also useful for rare abdominal wall hernias such as Spigelian hernias as they lie in between two layers of the abdominal wall, making these difficult if not impossible to palpate. CT is more costeffective and convenient than MRI, but both provide similar information. In addition, a CT scan is an important diagnostic tool in the setting of a bowel obstruction, as it may demonstrate an undiagnosed hernia as the cause. How About a Direct Inguinal Hernia?

For an indirect hernia, the main goal is to open the sac anteriorly , assess viability of the intestine, reduce any contents, and then perform a high ligation at the internal ring of the hernia sac. This eliminates the patent processus vaginalis. This is all that needs to be done in pediatric cases. The distal sac can be excised if small or left in situ if large. In addition, in adults, the long-standing protrusion of the hernia through the internal ring weakens the surrounding muscle. As such, the floor of inguinal canal is reinforced with a tension-free mesh repair Lichtenstein repair. With a direct hernia, since there is no patent processus vaginalis, the sac is not opened nor ligated. Since the sac consists of peritoneum and protrudes through the weakened floor of the inguinal canal, the sac is just reduced, and the floor of the inguinal canal is reinforced similarly to indirect hernias with a Lichtenstein repair.

An alternative to using mesh is to close the hernia defect and strengthen the floor by sewing the elements of the floor together as a tissue-based repair Bassini, Shouldice, McVay. Such repairs without mesh have the disadvantage of being under tension, and as such the hernia recurrence rates are significantly higher. These repairs are typically reserved for situations where mesh is unavailable, contraindicated infection, gangrenous bowel , or declined pain, preference, sensitivity. Laparoscopic inguinal hernia repair may be used to repair indirect, direct, and femoral hernias utilizing a posterior approach to the myopectineal orifice with mesh reinforcement. White arrows: normal inguinal canals.. Note that it is medial to the femoral vein and inferior to the inguinal ligament. White arrows: hernia sac. Black arrows: femoral vein. Black dotted line: location of inguinal ligament a Acutely incarcerated hernias are at risk of progressing to strangulation and require prompt attention.

Provided there is no evidence of strangulation already, an attempt should be made to reduce the incarcerated hernia. This is typically done by placing the patient in slight Trendelenburg position, providing some sedation and analgesia, applying a cold compress, and then attempting gentle manual compression. The advantage of reduction is that it converts an emergent procedure into a semi-elective one and makes the operation easier as there will be less inflammation. If the hernia is not reducible, urgent surgical intervention is required. The vast majority of hernias in infants are indirect hernias.

Thus, high ligation of the hernia sac alone adequately corrects this defect. Since pediatric hernias typically have a smaller internal ring relative to its final adult size, the internal ring and the floor of the inguinal canal do not need reinforcement. Umbilical hernias are very common in newborns. They rarely incarcerate and most close spontaneously by age 2. Indications for surgery are persistence beyond age 4, hernia defect larger than 2 cm in diameter unlikely to close spontaneously , strangulation, or progressive enlargement after 1—2 years of age. What Is the Mechanism of Injury? What Are the Consequences? Although the goal is to quickly restore blood flow to avoid bowel necrosis, this is not always possible, and the bowel may already be gangrenous upon presentation.

If reduced, the gangrenous bowel will be pushed back into the peritoneal cavity, leading to sepsis and peritonitis. The only safe approach to reducing a strangulated hernia is in the operating room after confirming the bowel is not dead. The distal sac, if small, is typically excised. However, if the indirect hernia sac is large, it will extend into and be adherent to the scrotum. In this situation the distal hernia sac may be left in situ. Attempting to remove the entire sac requires extensive dissection and carries an increased risk of disrupting the venous drainage of the testicle which is the leading cause of testicular ischemia.

CT scan can help demonstrate bowel obstruction in the preperitoneal hernia sac. The most common nerve injured during laparoscopic repair is the lateral femoral cutaneous nerve. There is ongoing debate as to whether asymptomatic inguinal direct and indirect hernias in adults should be repaired or whether one should wait for symptoms to develop. More recent studies confirm the safety of watchful waiting but suggest that the majority of asymptomatic patients eventually do become symptomatic. Most surgeons will offer elective repair of asymptomatic inguinal hernias. Since femoral hernias are at higher risk of incarceration, repair is routinely recommended.

However, premature infants are also at much higher risk of complications from surgery pulmonary from general anesthesia, injury to the vas deferens due to small size. Data regarding optical timing of repair are conflicting. Most pediatric surgeons agree that optimal management is to delay surgery until infant is out of the ICU. Is Mesh Needed for Repair? Incisional hernias typically develop after prior abdominal surgery. De novo ventral hernias will typically arise in the midline linea alba. Incisional hernia repairs, due to the fact that they are re-operative, have more risk, as adhesions may be encountered with potential bowel injury during surgery. Depending upon the size of the hernia defect, mesh is generally used for repair. Mesh decreases the chances of hernia recurrence compared to sutures alone. However, there are several potential mesh-­related complications that arise including mesh infection, recurrence, adhesions, pain, and erosion into the bowel with fistula formation.

Preferred techniques involve placing the mesh in an extraperitoneal position, to avoid contact with the bowel. Laparoscopic inguinal hernia repair has a slightly higher recurrence rate than open. However, most recurrences occur early in the learning curve for an individual surgeon, whereas outcomes are excellent with experienced laparoscopic surgeons. Conversely, open repair is associated with slightly more postoperative pain. Both are considered acceptable alternatives with similar results. Current recommendations define a clear benefit for laparoscopic hernia repair in cases of bilateral inguinal hernias less pain and for recurrent inguinal hernias after prior open repair less pain, similar results. Primary unilateral hernias may be repaired by either method. ȤȤ Wait until preemie is out of the ICU. Suggested Reading Abi-Haidar Y, Sanchez V, Itani KM.

She has had at least ten episodes of green, bilious emesis without blood. She has had no passage of stool or flatus per rectum since yesterday morning and has not eaten in 24 hours due to the vomiting and abdominal pain.

The history of acute onset of colicky abdominal pain, nausea, vomiting, and obstipation in a young patient with prior abdominal or pelvic surgery is highly suggestive of simple mechanical small bowel obstruction SBO due to adhesions from prior surgery.

This patient presents with uncomplicated or simple SBO. Treatment is necessary in order to avoid progression and potential complications such as strangulation, bowel necrosis, sepsis, and even death. Table 3. The absence of an abdominal scar markedly lowers the likelihood of adhesions, the most common etiology of SBO in the USA. Adhesions typically result from prior surgeries but may 23 Abdominal Pain, Nausea, and Vomiting rarely form due to prior abdominal infections, such as pelvic inflammatory disease or intestinal perforation. The majority of SBOs due to intra-abdominal adhesions will resolve with conservative treatment. On the other hand, most other causes of SBO are very likely to require surgical intervention and often emergently. Watch Out Hernias are the most common cause of SBO worldwide. absence of bowel sounds, and localized abdominal tenderness. Occasionally, a painful mass or blood in the stool may be found.

Unfortunately, these signs are not particularly sensitive or specific for early strangulation, but they should alert one to the possibility of strangulation and the need for early surgical intervention. Watch Out The four cardinal signs of strangulated bowel: fever, tachycardia, leukocytosis, and localized abdominal tenderness. Watch Out In a patient presenting with a history and exam suggestive of SBO, make sure to ask or look for abdominal scars from prior surgery e. A closed loop obstruction is a particularly dangerous form of bowel obstruction in which a segment of intestine is obstructed both proximally and distally. Vomiting will not relieve the obstruction nor will a nasogastric tube, as gas and fluid accumulates within this segment of bowel and cannot escape. This progresses rapidly to strangulation with risk of ischemia and perforation. This is suggestive of an obturator hernia and consists of pain in the medial aspect of the thigh with abduction, extension, or internal rotation of the hip due to compression of the obturator nerve by an obturator hernia pelvic hernias seen mostly in elderly multiparous females and in those with significant weight loss.

In SBO, gas and fluid accumulate proximal to the site of obstruction, causing dilation of the bowel followed by increased diffuse motility in attempt to overcome the obstruction. The increased peristaltic activity that attempts to overcome the obstruction in the early course of SBO causes the characteristic colicky pain. Since the increased motility is not localized, patients with SBO can present with diarrhea. The small bowel distention stretches visceral peritoneum, resulting in autonomic stimulation with progressive nausea and emesis. Failure to pass gas or stool per rectum is typically due to a complete mechanical obstruction of the small intestine. In contrast to a simple SBO where blood flow to the bowel remains intact, strangulated obstruction occurs when vascular perfusion is impaired, leading to intestinal ischemia and ultimately necrosis and perforation.

Strangulation accounts for almost half of all deaths due to SBO and increases the morbidity rate significantly. Early surgical intervention is essential to avoid morbidity and poor outcomes. Theoretically, bowel sounds are initially increased and should have a high-pitched, tinkling sound. As the bowel distends and intramural pressures rise, intestinal motility decreases, and bowel sounds diminish. Clinically, auscultation of bowel is not as useful in clinical practice when differentiating normal versus pathologic bowel sounds. In the presence of intestinal ischemia or perforated bowel, the bowel sounds may become absent. In general, lower abdominal operations have higher risk for SBO, compared to upper abdominal operations. Adhesions are caused by infection, foreign material sutures , tissue ischemia, or handling of the bowel. Inflammatory processes such as appendicitis and diverticulitis create adhesions as surrounding intestinal loops attempt to contain the source of inflammation and infection.

Disruption of the visceral and parietal peritoneum with pelvic operations leads to adhesions, especially in the dependent positions where the loops of the small intestine rest. Another possible explanation for the higher rate of SBOs after pelvic operations compared to abdominal operations is that the bowel is more mobile in the pelvis than in the upper abdomen and thus more likely to produce an obstructing torsion. Not always. One would expect the smaller incisions and minimally invasive dissections involved in laparoscopic surgery to be associated with a lower rate of postoperative adhesions and subsequent SBO. However, SBO following laparoscopic abdominal surgery can occur irrespective of the type of operation with the highest being in those undergoing laparoscopic cholecystectomy and appendectomy.

In some cases, laparoscopic repair has a higher risk for subsequent SBO, compared to an open repair e. Volume depletion is a common finding in SBO, but the mechanisms of fluid loss differ depending on the site and degree of obstruction. With proximal obstructions, repeated episodes of emesis as well as refusal of oral intake due to anorexia contribute to volume depletion and electrolyte abnormalities. With a complete obstruction, there is a transudative loss of fluid into the peritoneal cavity. The intestine proximal to the site of obstruction becomes distended due to the accumulation of gastrointestinal secretions and gas. Stasis in the intestinal lumen results in bacterial overgrowth, which causes even more dilation due to bacterial fermentation.

As the hydrostatic pressure within the intestinal lumen increases, fluid accumulates in the bowel wall, altering the Starling forces of capillary fluid exchange such that there is a net filtration of fluid, electrolytes, and protein into the bowel wall and lumen. This loss of fluid from the intravascular space is termed third spacing and contributes to volume depletion in both proximal and distal SBO. The above patient presents with a hypochloremic, hypokalemic metabolic alkalosis as a result of volume losses from recurrent emesis. The volume loss activates the renin-­ angiotensin-­ aldosterone system to increase sodium and water absorption from the distal convoluted tubules in the kidneys. In order to maintain ion balance, potassium is excreted in exchange for sodium. As the patient becomes progressively more hypokalemic which can lead to arrhythmias , the kidney will eventually excrete hydrogen ions instead of potassium ions, which perpetuates the systemic metabolic alkalosis and results in a paradoxical aciduria.

When working up SBO, it is important to obtain a complete blood count, chemistry panel, and serum lactate. While laboratory values do not play a significant role in the diagnosis of SBO, they are essential in assessing the degree of volume depletion and may raise the suspicion of bowel ischemia. Volume-depleted patients may exhibit hemoconcentration, as evidenced by elevated hemoglobin and hematocrit. A chemistry panel can also asses for hypochloremic, hypokalemic metabolic alkalosis, which often results from repeated bouts of emesis. Leukocytosis raises the possibility of an infectious etiology or bowel compromise, changing the management algorithm of a simple SBO. An elevated serum lactate or low serum bicarbonate , particularly associated with a non-anion gap metabolic acidosis, may indicate an ischemic bowel, as does hyponatremia.

When SBO is suspected, initial imaging should include an abdominal series. The small bowel has lines plicae circulares going all the way around the circumference of the bowel. The large bowel has lines haustra traversing only halfway through the bowel. If the patient is critically ill and unable to sit upright, a left lateral decubitus film is substituted. In a partial SBO, gas and fluid are able to pass. Patients with a complete SBO present with colicky abdominal pain, nausea, vomiting, and obstipation. Those with a partial SBO develop similar symptoms, but more slowly, and continue to pass gas and stool beyond 6—12 hours after symptom onset.

While plain films of a patient with complete SBO show dilated loops of bowel with air-fluid levels and no gas in the rectum, those with partial SBO will show residual colonic gas. Sometimes plain films will be equivocal, and CT 3 26 3 J. Chen will be necessary in order to visualize the amount of residual air and fluid in the distal intestine. It is important to distinguish between a complete and partial SBO because the management of these two conditions is different. The risk of strangulation is minimal for patients with partial obstruction, whereas the risk is substantial for those with complete obstruction.

Thus, a partial SBO can typically be managed nonoperatively, while complete SBO may require earlier surgical intervention. The clinical presentation of large bowel obstruction LBO is dependent upon location and etiology of obstruction. If the proximal colon is involved, it is more likely to be mistaken for SBO assuming the ileocecal valve is incompetent as the small intestine will become dilated too causing a similar clinical presentation. If a tumor is the cause of LBO, the course may be more insidious in onset, and symptoms may be chronic with less likelihood of confusion with SBO. In general, LBO causes gradually increasing abdominal pain, progressive distention, constipation, and occasionally feculent vomiting. There are longer intervals between episodes of cramping pain, and there is more pain in the suprapubic area with LBO than with SBO. Common causes of LBO include colon cancer, diverticular disease, and volvulus. Watch Out An obstructing sigmoid colon cancer can lead to a closed loop obstruction if the ileocecal valve is functional, as gas cannot exit into the small bowel or from rectum.

After abdominal surgery, GI motility is reduced due to a number of factors including a stress-induced sympathetic response, the release of inflammatory mediators, and the use of anesthetic and analgesic agents. The small intestine usually regains normal motility within the first 24 hours after surgery, the stomach takes 48 hours, and the colon can take as long as 3—5 days. This phenomenon is physiologic and is referred to as postoperative ileus. It may be difficult to distinguish postoperative ileus from early SBO, since postoperative ileus also presents with abdominal pain, nausea, vomiting, and abdominal distention.

Ileus, however, usually presents with absent or hypoactive bowel sounds, and the pain is described as dull and constant. One should suspect SBO if bowel function initially returned and subsequently the patient developed obstructive symptoms. Plain films should reveal dilated loops of bowel but no air-fluid levels in ileus. If x-rays are nondiagnostic, CT is very effective in differentiating SBO from postoperative ileus and will often reveal the etiology of postoperative SBO in many cases. Watch Out Gallstone ileus is a misnomer as this is a type of mechanical SBO where a large gallstone travels through a cholecystoduodenal fistula and becomes impacted in the narrower caliber distal small bowel near the ileocecal valve.

Patients with SBO are often significantly volume depleted. Aggressive fluid resuscitation with an isotonic intravenous fluid such as normal saline and electrolyte repletion are critical initial steps in the management. Additionally, early placement of a nasogastric NG tube to evacuate air and fluid is important because gastric decompression will decrease nausea, vomiting, distention, and the risk of aspiration. The more significantly ill patient should have an indwelling bladder catheter placed to monitor hourly urine output. Early administration of oral contrast has been used for diagnostic and therapeutic purposes in the management of SBO.

Passage of contrast to the large intestine predicts resolution and expedites the course of nonoperative management. Lack of passage predicts failure of conservative management, and early intervention improves outcomes and expedites management. The high osmotic load of oral contrast may help to resolve early partial SBO, as Gastrografin increases intraluminal water content and decreases bowel wall edema. Evidence is limited, but results from a recent multi-institutional, prospective observational study suggest that patients with SBO due to adhesions may benefit from Gastrografin, with lower rates of operative intervention and shorter length of stay in the hospital. Watch Out Gastrografin enema is also useful in resolving meconium obstruction in neonates. If the patient develops symptoms or signs of bowel compromise increasing abdominal pain and tenderness on exam , the patient should then promptly be taken to the operating room. In the absence of such signs, it should be determined whether the SBO is partial or complete.

The management of partial SBO is an initial trial of nonoperative management due to the fact that progression to strangulation is unlikely. However, if a patient with partial SBO begins to clinically deteriorate, prompt operative intervention may be necessary. The management of complete SBO or of a patient with evidence of ischemic bowel is urgent surgical intervention. Necrotic bowel generally does not occur in association with an SBO unless there is a closed loop obstruction. Any bowel that is obviously nonviable needs to be resected.

If there are segments of bowel of questionable viability, there are several methods to assess viability. In addition, the bowel can be interrogated using a hand-held Doppler to detect audible arterial signals on the antimesenteric border of the questionable bowel. Finally, intravenous fluorescein dye can be administered. If the viability remains in question, and it is a small segment, the segment should be resected. If there is a large segment of questionable viability where resecting it could lead to short gut syndrome , the bowel can be left intact, the abdomen is kept open with a negative pressure wound covering , and a second-look operation is performed to assess viability the following day after the patient has been warmed and further resuscitated. Early postoperative SBO is uncommon, and most can be managed nonoperatively. If the diagnosis of acute postoperative SBO is made, an attempt to classify it as partial or complete is needed.

Although most early postoperative SBO are partial obstructions, one must be able to detect complete obstruc- tion to prevent serious complication or bowel compromise. Partial obstruction should be managed conservatively, and in the postoperative setting, up to 3 weeks of nonoperative therapy may be acceptable.
