Summary: Complications like leaks after one-anastomosis gastric bypass (OAGB) should be managed properly, but there is limited data and no guidelines for leak management. A systematic review and meta-analysis of 46 studies involving 44,318 OAGB patients found a 1% prevalence of leaks. Surgical strategies varied, but about 62.1% of patients with leaks required additional surgery. The most common procedures for leak management were peritoneal washout and drainage, followed by conversion to Roux-en-Y gastric bypass. The mortality rate related to leaks was 1.95%.

Summary: Obesity surgery is performed for sustained weight loss, increased life expectancy, and reduction of complications. Complications can vary based on the procedure and early diagnosis and intervention of bowel injury are crucial for reducing morbidity and mortality.

Summary: One anastomosis gastric bypass (OAGB) is as effective as Roux-en-Y gastric bypass (RYGB) in improving metabolism and weight loss. Shortening the biliopancreatic limb of OAGB can improve metabolic parameters without significantly affecting weight.

Summary: This study compared nutritional deficiencies and metabolic markers one year after OAGB and SG procedures. The results showed a higher risk of nutritional deficiencies after OAGB, but this risk can be minimized with nutritional recommendations and supplement plans, resulting in comparable metabolic improvement to SG after one year.

Summary: The results of the study showed that patients who underwent tailored bypass had significantly greater weight loss and total weight loss at 6 and 12 months postoperatively compared to those who received fixed bypass. There was no significant difference between the two groups in terms of improvement in comorbidities, but the fixed bypass group had a significantly higher complication rate than the tailored bypass group. Both groups showed similar changes in nutritional parameters at 12 months postoperatively, except for higher serum albumin levels in the tailored bypass group.

Summary: Our study in Gottingen minipigs found that the effects of OAGB on weight loss, glucose metabolism, and bile acids are mainly mediated by the length of the common limb, while the length of the biliary limb contributes to body weight loss. Resection of the biliary limb prevented weight loss effects, while resection of the common limb reproduced glucose metabolism effects and changes in intestinal BAs.

Summary: The study aims to provide guidance for bariatric surgeons in determining the optimal length of the biliopancreatic (BP) limb in one anastomosis gastric bypass (OAGB) surgeries by comparing the effect of tailored BP-limb length based on total small bowel length (TSBL) with a fixed BP-limb length.

Summary: Gastric bypass and biliopancreatic diversion procedures have evolved from loop configurations to Roux-en-Y configurations and back to loop configurations as one anastomosis gastric bypass and single-anastomosis duodenal switch. Surgeons often do not measure the lengths of the common channel (CC) and biliopancreatic limb (BPL), resulting in variable outcomes related to limb length. This article evaluates the literature on the effects of varying limb lengths on the outcomes of Roux-en-Y gastric bypass.

Summary: This study presented the preliminary results of 44 patients who underwent a modified one-anastomosis gastric bypass procedure with good weight loss outcomes and no apparent increase in complications compared to traditional surgery. Randomized studies with longer term follow-up are needed for further evaluation.

Summary: The increasing rate of obesity and life expectancy will result in more bariatric procedures in the elderly population. This study examined the early adverse events of One-Anastomosis Gastric Bypass (OAGB) in elderly patients compared to non-elderly patients. The results showed that the elderly group had longer hospital stays and higher readmission rates, but the overall rates of adverse events and reoperation were similar between the two groups.

Summary: This study aimed to present our SASI procedure based on the experience with OAGB and provide surgical outcomes. Thirty patients with obesity underwent SASI surgery with satisfying results, including no conversion to open surgery and favorable operative time, blood loss, and hospital stay. After 6 months, patients showed weight loss and improvement in related metabolic syndrome.

Summary: This study retrospectively reviewed patients who underwent laparoscopic resizing of the gastric pouch (LPR) after weight regain (WR) following gastric bypass procedures. The results showed that LPR had good outcomes in terms of weight loss and improvement of comorbidities, with an acceptable rate of complications and operative time.

Summary: This study investigated the <= 30-day outcomes of one-anastomosis gastric bypass (OAGB) used in primary (pOAGB) and revisional (rOAGB) procedures, and identified predictors of early complications. The results showed that OAGB is a safe procedure with common complications including bleeding, leaks, and obstruction/stricture.

Summary: Compared to Roux-en-Y gastric bypass, patients undergoing single anastomosis gastric bypass tend to be younger with slightly higher BMI. After adjusting for comorbidities, single anastomosis gastric bypass is associated with a lower incidence of serious complications.

Summary: This study compared the effects of one anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) surgeries on weight loss and resolution of comorbidities. The results showed that at the 5-year follow-up, patients from both groups achieved similar outcomes in these aspects, with no major complications.
