Small bowel obstruction (SBO) after bariatric surgery is well documented. Although infrequent, it can be associated with considerable morbidity and mortality. The laparoscopic approach to Roux-en-Y gastric bypass (LRYGB) has gained widespread popularity for the treatment of morbid obesity since its first description in 1994. One of the theoretical advantages of a minimally invasive technique is reduced intraabdominal adhesions and, consequently, diminution in the incidence of SBO. However, the laparoscopic approach demonstrates a similar rate of obstruction to the open procedure. In this review, an electronic literature search was undertaken of Medline, Embase, and Cochrane databases for the period January 1990 to October 2006 on the history, presentation, clinical evaluation, preoperative diagnostic techniques, and management of SBO after LRYGB compared to the open approach.

    ABSTRACT: We report on two cases of small bowel obstruction in the setting of a previous laparoscopic adjustable gastric band insertion. In both cases, a closed loop obstruction was created by the band and delayed diagnosis resulted in significant morbidity. Early recognition with deflation of the adjustable gastric band and nasogastric tube insertion is paramount to managing these patients.

    ABSTRACT: We describe an afferent loop obstruction in a patient who had a subtotal gastrectomy with Roux-en Y gastrojejunostomy for postvagotomy syndrome. The clinical presentation and initial studies suggested acute pancreatitis. A computed tomography scan showed a small bowel obstruction distal to the jejunojejunal anastomosis. The patient was taken to the operating room for an exploratory laparotomy, lysis of adhesions, and closure of her jejunostomy. Surgery was successful at resolving her obstruction. In any Roux-en-Y gastric reconstruction or gastric bypass patient presenting to the emergency department with abdominal pain and elevated transamines or pancreatic enzymes, a small bowel obstruction must be considered. Additional imaging with a computed tomography scan is advocated, as well as surgical consultation.

    ABSTRACT: bariatric surgery presented a dramatic increase due to the obesity epidemics and the laparoscopic approach. General surgeons might face acute or chronic complications of bariatric surgery, considering the increasing figures of obesity procedures performed every year in USA, as well as in Europe. to present the possible surgical emergencies after bariatric surgery. laparoscopic adjustable gastric banding is the most widely performed bariatric procedure in Europe. Acute anterior/posterior slippage of the gastric wall is the most frequent complication, and needs emergency treatment: band's deflation, laparoscopy for repositioning/removal. Intragastric band migration is diagnosed at the radiological or endoscopic controls and usually does not represent a surgical emergency. Anastomotic marginal ulcer may appear after gastric bypass GBP or biliopancreatic diversion BPD (with/without duodenal switch DS), and can be complicated by bleeding or rarely by perforation. Small bowel obstruction due to internal hernia after GBP or BPD represents major emergency that can be caused as well by trocar site hernia, intussusceptions, adhesions, strictures, kinking or blood clots. Correct diagnosis and immediate treatment are mandatory. Rapid weight loss after bariatric surgery can cause gallbladder diseases and choledocholitiasis that can be difficult to treat after gastric bypass procedures. General surgeon has to know the most diffuse bariatric procedures and their complications and to treat them as other gastrointestinal surgical procedures. Minimally-invasive approach should be considered in most of the cases, but the approach depends on the general surgeon's experience.
