Laparoscopic Roux-en-Y bypass is being increasingly used for weight reduction in patients with morbid obesity. Unfortunately, some complications can occur after this procedure, the most frequent being intestinal obstruction (due to stenosis of the anastomosis at the distal end of the loop, internal hernias, bands, and adhesions), anastomotic leaks, and bleeding. This article provides basic knowledge about the surgical technique and its correlation with the common postoperative changes with the aim of facilitating the interpretation of CT findings and the identification of postoperative complications in these patients.

Bariatric surgery is the most effective treatment for morbid obesity. Due to the high volume of weight loss procedures worldwide, the general surgeon will undoubtedly encounter bariatric patients in his or her practice. Liberal use of CT scans, upper endoscopy and barium swallow in this patient population is recommended. Some bariatric complications, such as marginal ulceration and dyspepsia, can be effectively treated non-operatively (e.g., proton pump inhibitors, dietary modification). Failure of conservative management is usually an indication for referral to a bariatric surgery specialist for operative re-intervention. More serious complications, such as perforated marginal ulcer, leak, or bowel obstruction, may require immediate surgical intervention. A high index of suspicion must be maintained for these complications despite "negative" radiographic studies, and diagnostic laparoscopy performed when symptoms fail to improve. Laparoscopic-assisted gastric band complications are usually approached with band deflation and referral to a bariatric surgeon. However, if acute slippage that results in gastric strangulation is suspected, the band should be removed immediately. This manuscript provides a high-level overview of all essential bariatric complications that may be encountered by the acute care surgeon.

The laparoscopic adjustable gastric band (LAGB) is a widely performed procedure for the morbid obesity epidemic. Despite its low mortality compared with other mainstream bariatric surgeries, it is not without its complications. The authors report a late and rare complication of a small bowel obstruction in a 52-year-old woman from an LAGB placed for 2 years. She was diagnosed clinically and radiologically with a small bowel obstruction. However, in the setting of an LAGB, this became a closed-loop obstruction. She proceeded to an emergency laparoscopy, which revealed that the port connection tube had formed dense adhesions to the jejunum causing an obstructive band. This is only the fifth reported case in Australia; as bariatric surgery continues to rise, these patients may present unannounced to any emergency department and as such should be treated as a closed-loop obstruction with immediate resuscitative and surgical management instituted.

Bariatric/metabolic surgery is currently the only effective long-term treatment for morbid obesity- and obesity-related diseases such as diabetes, heart disease, hypertension, obstructive sleep apnea, and dyslipidemia. In addition, bariatric/metabolic surgery has been shown to significantly reduce the incidence of diabetes and cancer and prolong life when compared to non-surgical therapies. However, as obesity is a chronic disease, recidivism of weight and comorbid conditions can occur. In addition, the surgical construct can lead to long-term consequences such as marginal ulceration, bowel obstruction, reflux, and nutritional deficiencies. Despite these drawbacks, prospective randomized controlled studies and long-term longitudinal population-based comparative studies greatly favor surgical intervention as opposed to traditional lifestyle, diet, and exercise programs. Revisional surgery can be quite complex and technically challenging and may offer the patient a wide variety of solutions for treatment of weight recidivism and complications after primary operations. Given the paucity of high quality published data, we have endeavored to provide indications for revisions after bariatric surgery.

Small bowel intussusception is an uncommon cause of adult intestinal obstruction after gastric bypass for morbid obesity. It usually affects the Roux or the common limb at the jejunojejunostomy site and is mainly retrograde. An altered motility of the Roux limb seems to be the main explanation for its developement. We report the case of a patient with a late acute anterograde intussusception after a previous distal Roux-en-Y gastric bypass. Clinical, radiological and operative findings are presented and surgical solutions described in the literature are reviewed.

The aim of this study was to compare postoperative outcomes after robotic-assisted and laparoscopic bariatric sleeve gastrectomy (SG). Sleeve gastrectomy is traditionally performed using laparoscopic techniques. Robotic-assisted surgery enables surgeons to perform minimally invasive SG, but with unknown benefits. Using a national database, we compared postoperative outcomes after laparoscopic SG and robotic-assisted SG. National data from individuals undergoing elective SG in the National Inpatient Sample database between 2011 and 2013 were analyzed. Propensity score matching was used to match robotic and laparoscopic groups by demographics, comorbidities, and hospital characteristics. The matching cohorts were compared. A total of 26,195 patients who underwent elective SG for morbid obesity were included. Of these, 25,391 (96.9%) were completed via laparoscopy, whereas 804 (3.1%) were performed with robotic assistance. There were no significant differences in demographics and subsequent postoperative complications. The inhospital mortality was similar. Length of hospital stay was statistically different, with a mean of 1.88 in laparoscopic versus 2.08 days in robotic (P < 0.001). Higher total hospital charges were noted in the robotic-assisted SG group (median US$38,569 vs US$54,658, P < 0.001). These differences were evident even after adjusting for confounding factors: wound infection, atelectasis, bowel obstruction, pneumonia, and bowel obstruction (P < 0.001).

Roux-en-Y gastric bypass (RYGB) is considered the gold standard for weight loss surgery and is an effective, safe treatment for morbid obesity and associated metabolic derangements. Complications such as small bowel obstruction are rare with a reported incidence of 5%. Obstruction caused by hiatal herniation of the gastric pouch and alimentary limb occurs even less frequently. Prompt recognition and treatment are imperative as delayed intervention may result in significant morbidity. At the time of this manuscript there have only been four reported cases in the literature highlighting a paucity of clinical guidance for the recognition and management of this complication. Here we present a case of acute small bowel obstruction secondary to hiatal herniation of the gastric pouch and proximal Roux limb. Furthermore, we review the literature and discuss the key aspects for the management of this complication.
