Small intestinal obstruction remains a frequently encountered problem in abdominal surgery. Although modern day surgical management continues to focus appropriately on avoiding operative delay whenever surgery is indicated, not every patient is always best served by immediate operation. Certain entities, such as SBO secondary to incarcerated abdominal wall hernia, and patients with clinical signs and symptoms suggestive of strangulation do require prompt operative intervention. Other conditions, however, such as postoperative adhesions and neoplastic-associated SBO, particularly in patients with numerous previous abdominal procedures, concomitant medical problems, or incomplete or partial obstruction, often justifiably benefit by a trial of nonoperative management. The risk of strangulation with adhesive and neoplastic SBO is relatively low as compared with incarcerated hernia and small bowel volvulus. Close and careful clinical evaluation, in conjunction with laboratory and radiologic studies, will usually dictate the proper course of management in any given case. If any uncertainty exists, prompt operative intervention is indicated. Because over 50 per cent of all cases of SBO are the direct result of postoperative adhesions, it is probably just as important as the actual management of SBO for all practicing abdominal surgeon to familiarize themselves with the widely accepted "ischemic theory" of adhesion formation. A number of intraoperative measures, many of which go against established surgical principles, are now encouraged during routine elective abdominal surgery to reduce the incidence of detrimental adhesions that might subsequently produce SBO. At the same time, surgeons should continue their aggressive attitude towards elective repair of any and all abdominal hernias, which continue to account for close to 15 per cent of all cases of small intestinal obstruction and still remain the most common cause of strangulation.

Small bowel obstruction due to lesser sac herniation through both the gastrocolic and gastrohepatic omenta is extremely rare, and only a few reported cases have been concerned with imaging diagnosis. CT images showed distended bowel loops at the level of the cephalad part of the stomach, collapsed triangular loops and attached mesentery were depicted just behind the caudal part of the stomach. These findings provided clues to the diagnosis of this type of lesser sac hernia.

Laparoscopic hernia repair is a frequently performed operation. Although it has many advantages over open inguinal hernia repair, laparoscopic surgery is not without complications. Small bowel obstruction is a complication unique to laparoscopic repair of inguinal hernias. It is reported following transabdominal preperitoneal repairs. We present a case of small bowel incarceration through a peritoneal defect after a totally extraperitoneal inguinal hernia repair. Techniques to avoid this complication are presented. The literature is reviewed.

Obesity is rapidly becoming the most important public health issue in USA and Europe. Roux-en-Y gastric bypass is now established as the gold standard for treating intractable morbid or super obesity. We reviewed the imaging findings following this surgery in 234 patients. In this pictorial essay we present the CT and upper gastrointestinal contrast study appearances of the expected postoperative anatomy as well as a range of abdominal complications. The complications are classified into leaks, fistula and obstruction. Postoperative gastric outlet and small bowel obstruction can be caused by anastomotic stenosis, mesocolic tunnel stenosis, adhesions, stomal ulcer, obturation, intussusception and internal or external hernia. Small bowel obstruction may be of a simple, closed loop and/or strangulating type. The radiologist should be able to diagnose the type and possible cause of obstruction.

Small bowel obstruction is an unusual complication of pregnancy. Its occurrence after Roux-en-Y gastric bypass (RYGB) for morbid obesity complicated by pregnancy is rare. Morbid obesity describes body weight at least 100 lb over the ideal weight, or a body mass index (BMI) > or = 40. Surgery offers the only viable treatment option with long-term weight loss and maintenance. This case report involves a 23-year-old female at 25 weeks gestation with a 1-day history of diffuse abdominal pain and vomiting. She had a RYGB with a 15 cc micropouch 6 months prior to the commencement of this pregnancy. All radiologic investigations were normal. Esophagogastroscopy was performed revealing an ischemic Roux limb of the gastric bypass. At laparotomy, an internal hernia involving the afferent limb was identified at the site of the Roux anastomosis compromising portions of both the afferent and Roux limbs. Nonviable portions of both the afferent and Roux limbs were resected. Gastrointestinal continuity was achieved by fashioning a gastro-gastrostomy and a jejuno-jejunostomy, thus reversing the original gastric bypass procedure. The immediate postoperative period was complicated by fetal demise. With the increase in bariatric surgery, small bowel ischemia after Roux-en-Y gastric bypass will most likely become more prevalent, particularly in women of childbearing age.

Small bowel obstruction in children is most frequently seen secondary to postsurgical adhesions. In rare circumstances, obstruction may be the result of an internal hernia through or around the falciform ligament. We report the first case of a strangulated internal hernia around the falciform ligament in a young girl.

Small bowel obstruction is caused by postoperative adhesions in most patients. The traditional surgical treatment has been laparotomy with adhesiolysis and possible resection of the ischaemic intestine. The laparoscopic approach has proved feasible but not without risks. We analysed our experience in the management of acute small bowel obstruction and then reviewed the literature in an attempt to identify the real role of laparoscopy. From January 2003 to June 2008, 19 patients operated on for small bowel obstruction were identified. We evaluated our performance in terms of the aetiology of the obstruction, operative time, length of postoperative hospital stay, conversion rate, and major morbidity and mortality. Postoperative adhesions were responsible for the occlusion in 13 cases; a single band was identified in 47% of patients (9 cases). Neoplastic disease (3 cases), a gallstone ileus, Crohn's disease and an internal hernia were the remaining cases. Laparoscopic treatment was only possible in 7 patients with single adhesions (77%), and a conversion was carried out in the remaining 12 cases (63%), including "laparoscopy-assisted" cases (6 cases). The duration of the intervention (89 +/- 21 min vs 135 +/- 27.5 min) and postoperative hospitalisation (3.6 +/- 1 days vs 6.25 +/- 1.6 days) were in favour of the completely laparoscopic group as compared to the laparoscopy-assisted group. A case of postoperative peritonitis due to bowel perforation required a second intervention. With an appropriate selection of patients, confirming the high incidence of the single adhesions responsible for the occlusion and the resulting high success rate of laparoscopy, we believe that only an initial laparoscopic approach can help identify such favourable situations.

Small bowel obstruction (SBO) is a common cause of hospital admission. Our objective is to determine variables that correlate with failure of the laparoscopic approach for SBO. Twenty-three consecutive patients underwent diagnostic laparoscopy with curative intent for treatment of SBO by a single surgeon over a 3-year period. The laparoscopic approach was successful in 18 patients (78%); there were five (22%) conversions to laparotomy. The causes of obstruction included adhesive band in 16 patients; and small bowel lymphoma, metastatic esophageal cancer, small bowel gangrene, Meckel diverticulum, gallstones ileus, and incarcerated incisional hernia in two. Using the Fisher two-sided test, no significant predictor for conversion was identified using gender, American Society of Anesthesiologists class, previous bowel obstruction, history of adhesiolysis, abdominal distention, pelvic surgeries, chemotherapy, radiation, malignancy, chronic obstructive pulmonary disease, asthma, coronary artery disease, hypertension, or hypercholesterolenemia. The Wilcoxon two-sided test did not show significance for age, weight, number of previous abdominal surgeries, or small bowel diameter. The postoperative hospital stay was significantly shorter in the laparoscopic group compared with those who needed conversion (3 vs. 9 days) with P = 0.0019. No mortality was noted in any patients. The laparoscopic is safe and feasible for the management of SBO. We believe that the laparoscopic approach should be offered to all patients with SBO unless there is an absolute contraindication to laparoscopic surgery.

Small bowel obstruction due to an internal hernia is an uncommon finding and, when caused by a defect in the broad ligament, it is exceptionally rare. This condition should be considered when evaluating all female patients presenting with de novo small bowel obstruction. We report an unusual case of intestinal obstruction from an internal hernia through the left broad ligament in a middle-aged patient with no prior surgical history and discuss the relevant literature and treatment. Although an oncologic diagnosis should be entertained, a small bowel obstruction arising in the pelvis may involve the broad ligament in parous patients. An internal hernia through the broad ligament should be considered in the differential diagnoses of female patients presenting with intestinal obstruction.
