Summary: While one anastomosis/mini gastric bypass is now acknowledged as a standard bariatric and metabolic surgical procedure, there are still some controversial issues that require further long-term data and research for a consensus.

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: OAGB/MGB as a revisional procedure after restrictive bariatric procedures shows promising outcomes in reducing BMI, improving T2DM remission rates, and increasing GERD remission/improvement rates, but potential complications such as leakage should be noted.

Summary: According to the latest IFSO recommendations, bariatric and metabolic surgery is recommended for patients with a BMI above 35 kg/m(2) to achieve weight loss and improve comorbidities. Patients with obesity have a higher incidence of GERD, for which Nissen fundoplication has been the standard treatment. However, gastric bypass is a valid option for obese patients. In this case report, a patient who previously underwent laparoscopic Nissen surgery for GERD experienced intrathoracic migration and symptoms, and revision bariatric surgery was offered. The video presents the performance of OAGB in this patient, which is a more complex procedure but provides good symptom control.

Summary: Internal hernia (IH) after OAGB is less common, with a 2.8% incidence rate and low risk of bowel ischemia or need for resection. Laparoscopic surgery is typically performed with an 8.3% postoperative morbidity rate and a low long-term relapse rate.

Summary: The study found no significant difference in nutritional status at the 6-month follow-up between patients undergoing RYGB and OAGB surgery. Both procedures may lead to malnutrition, with OAGB potentially more effective in inducing remission of type II diabetes and hypertension. More large prospective studies are needed to confirm the impact of different bypass procedures on nutritional status.

Summary: The study found that serum vitamin D levels significantly increased in patients undergoing OAGB surgery within 12 months post-surgery, with no significant correlations between vitamin D concentrations and weight, body mass index, lipid profile, ferritin, glycemic indices, and albumin.

Summary: One anastomosis gastric bypass (OAGB) is gaining popularity among bariatric surgeons worldwide due to its simplicity and efficacy. However, this study found that patients with a narrower stoma size (30 mm) initially had better weight loss outcomes compared to those with a wider stoma (45 mm), but the difference disappeared at mid-term follow-up after 2 years.

Summary: The prevalence of OAGB/MGB reversal is 1% with a complication rate of 10.9%. Protein-energy malnutrition is the most common etiology, highlighting the need for special attention to the nutritional status of OAGB/MGB patients.

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 article presents a case study of a 27-year-old Asian female patient who underwent a revisional bariatric surgery after poor response to the primary surgery. The laparoscopic procedure successfully controlled her weight and achieved remission of diabetes without any complications.

Summary: This study evaluated the effect of resecting the gastric fundus and corpus as an addition to OAGB on postoperative outcomes and found that this additional procedure had no impact on postoperative weight loss or metabolic outcomes.

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: Laparoscopic conversion from OAGB to RYGB is technically feasible with a moderate rate of postoperative complications. Severe (bile) reflux is a serious long-term complication after OAGB, with 4.1% of patients needing conversion to RYGB. Endoscopy after OAGB in patients showing clinical symptoms of gastroesophageal reflux disease is strongly advised to detect underlying pathologic changes.

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.
