Abstract Background Internal hernia (IH) represents a relatively common and well-known complication after Roux-en-Y gastric bypass. IH after one anastomosis gastric bypass (OAGB) is less frequent and rarely reported in the literature. This study presents a series of IH after OAGB observed in a high-volume bariatric center. Methods Data of patients who underwent OAGB with an afferent limb of 150 cm between May 2010 and September 2019 were prospectively collected and retrospectively analyzed. Data of patients undergoing surgery for IH during follow-up were collected and analyzed. Results Ninety-six patients out of 3368 with a history of OAGB had intestinal incarceration in the Petersen’s orifice (2.8%). Specificity and sensitivity of computed tomography scans in the diagnosis of IH were 59% and 76%, respectively. The mean timeframe between OAGB and surgery for IH was 21.9±18.3 months. Mean body mass index at the time of IH surgery was 24.7 ± 3.6. Surgery was completed laparoscopically in 96.8% of cases. Nine patients (9.3%) had signs of bowel hypovascularization. In all patients, the herniated bowel was repositioned, and the Petersen’s orifice was closed, without the need for bowel resection. Mean hospital stay was 1.9 ± 4.8 days. The postoperative morbidity rate was 8.3%. Long-term IH relapse was observed in 14 patients; signs of bowel hypovascularization due to incarceration in a small orifice was observed in eight of these patients (57%). Conclusions Incidence of IH after OAGB is 2.8%. IH is associated with a low rate of bowel ischemia and the need for intestinal resection.

Abstract Purpose The treatment of people with severe obesity and BMI > 50 kg/m2 is challenging. The present study aims to evaluate the short and mid-term outcomes of one anastomosis gastric bypass (OAGB) with a biliopancreatic limb of 150 cm as a primary bariatric procedure to treat those people in a referral center for bariatric surgery. Material and Methods Data of patients who underwent OAGB for severe obesity with BMI > 50 kg/m2 between 2010 and 2017 were collected prospectively and analyzed retrospectively. Follow-up comprised clinical and biochemical assessment at 1, 3, 6, 12, 18, and 24 months postoperatively, and once a year thereafter. Results Overall, 245 patients underwent OAGB. Postoperative mortality was null, and early morbidity was observed in 14 (5.7%) patients. At 24 months, the percentage total weight loss (%TWL) was 43.2 ± 9, and percentage excess weight loss (%EWL) was 80 ± 15.7 (184 patients). At 60 months, %TWL was 41.9 ± 10.2, and %EWL was 78.1 ± 18.3 (79 patients). Conversion to Roux-en-Y gastric bypass was needed in three (1.2%) patients for reflux resistant to medical treatment. Six patients (2.4%) had reoperation for an internal hernia during follow-up. Anastomotic ulcers occurred in three (1.2%) patients. Only two patients (0.8%) underwent a second bariatric surgery for insufficient weight loss. Conclusion OAGB with a biliopancreatic limb of 150 cm is feasible and associated with sustained weight loss in the treatment of severe obesity with BMI > 50 kg/m2. Further randomized studies are needed to compare OAGB with other bariatric procedures in this setting. Graphical abstract

Internal herniation is a well-described complication after a gastric bypass, particularly when performed laparoscopically, although it is rarely described following a total gastrectomy. A 55-year-old lady presented with a 24-hour history of vomiting and rigors 10 months after a radical total gastrectomy with Roux-en-Y reconstruction for a gastric adenocarcinoma. Computed tomography (CT) showed a complete small bowel obstruction and a mesenteric swirl sign, indicating a possible internal hernia. The entire small bowel was found at laparotomy to have migrated through the mesenteric defect adjacent to the site of the previous jejunojejunostomy and was dark purple and aperistaltic. The small bowel was reduced through the defect. At a second laparotomy, the small bowel looked healthy and the defect was repaired. Postoperative recovery was unremarkable. Of numerous signs described, the mesenteric swirl sign is considered the best indicator on CT of an internal hernia following Roux-en-Y reconstruction in gastric bypass surgery. A swirl sign on CT in a patient with abdominal pain should always raise the suspicion of an internal hernia.

Abstract Background Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a technically demanding procedure. The learning curve of LRYGB is challenging and potentially associated with increased morbidity. This study evaluates whether a general laparoscopic surgeon can be safely trained in performing LRYGB in a peripheral setting, by comparing perioperative outcomes to global benchmarks and to those of a senior surgeon. Methods All consecutive patients undergoing primary LRYGB between January 2014 and December 2017 were operated on by a senior (A) or a trainee (B) bariatric surgeon and were prospectively included. The main outcome of interest was all-cause morbidity at 90 days. Perioperative outcomes were compared with global benchmarks pooled from 19 international high-volume centers and between surgeons A and B for their first and last 30 procedures. Results The 213 included patients had a mean all-cause morbidity rate at 90 days of 8% (17/213). 95.3% (203/213) of the patients were uneventfully discharged after surgery. Perioperative outcomes of surgeon B were all within the global benchmark cutoffs. Mean operative time for the first 30 procedures was significantly shorter for surgeon A compared with surgeon B, with 108.6 min (± 21.7) and 135.1 min (± 28.1) respectively and decreased significantly for the last 30 procedures to 95 min (± 33.7) and 88.8 min (± 26.9) for surgeons A and B respectively. Conclusion Training of a new bariatric surgeon did not increase morbidity and operative time improved for both surgeons. Perioperative outcomes within global benchmarks suggest that it may be safe to teach bariatric surgery in peripheral setting.

We report the case of a 69-year-old man with a history of esophagogastric junction cancer (Barrett’s esophageal cancer; pT1b [SM], N0, M0, pStage IA) that was surgically resected 2 years prior to the present episode. Recurrence was not observed during follow-up. Following complaints of dysphagia and abdominal pain, computed tomography revealed signs of internal hernia. Thus, laparoscopic exploration was performed. Intraoperatively, accumulation of chylous ascites accompanying the internal hernia through the jejunojejunostomy mesenteric defect was observed, which was successfully treated with laparoscopic hernia reduction and defect closure by sutures without intestinal resection. Here, we discuss the case and report that along with previous studies, our study suggests that chylous ascites might be a reliable sign of intestinal viability for herniated intestines.

Laparoscopic diverted one-anastomosis gastric bypass (D-OAGB) is a bariatric procedure combining the principles of restriction, malabsorption, and other factors to induce weight loss. It is achieved by creating a narrow, long gastric pouch and bypassing a part of the small bowel (biliopancreatic limb). D-OAGB was first described by Dr. Ribero in 2013 and is technically a variation of the very heterogeneous group of Roux-en-Y gastric bypass operations. There are different technical variants to perform D-OAGB and to organize pre- and postoperative care. The following article is based on the approach to bariatric surgery as taken at the Department of General Surgery at the Medical University of Vienna. This article focuses on patient preparation before bariatric/metabolic surgery with mandatory and optional preoperative examinations to find the surgical procedure best suited for each individual patient and to decrease the patient’s risk. The surgical technique of D-OAGB itself, including positioning of the patient and related technical highlights, as well as the specifics of the postoperative course, are described. D-OAGB is an effective procedure for patients with symptomatic gastroesophageal reflux for adequate weight loss and remission of comorbidities with a low risk of malnutrition. For D-OAGB to be successful, important technical steps, such as creating a narrow, long pouch, exact length of the biliopancreatic and alimentary limb, and additional hiatoplasty (if necessary), should be taken. In terms of the postoperative course, regular checkups are vital to ensure desirable outcome in the long-term follow up and early detection of adverse developments.
