Background Recently the performance rate of one anastomosis gastric bypass (OAGB) bariatric surgery has increased. Bile reflux is on of common considered complication of OAGB challenging surgeon. Methods We searched English full text with keyword “bile reflux” AND “OAGB” OR “one anastomosis gastric bypass” OR “SAGB” OR “single anastomosis gastric bypass” that published from January 1st, 2000 to December 31st, 2020 in PubMed, EMBASE, Google scholar and Cochrane Library. We included prospective or retrospective systematic review, review, clinical, and meta-analysis human article that its full text was available and focused on bile reflux after OAGB/SAGB as the fundamental performed bariatric surgery. Results A total of 1259 articles were analyzed, of which 5 were included. Analysis of number articles by year revealed that 2019 and 2020 was the highest number of published articles (n = 232; 68%). Study type analysis revealed that review studies and clinical research (n = 62; 18.2%) were the most frequent study types. Reported data on bile reflux after OAGB had diversity. Implicitly, postoperative incidence of bile reflux differed from 7.8 to 55.5%. General consensus was not existed among authors to consider the OAGB as the first suspect leading to postoperative bile reflux among other bariatric surgery types. Conclusion Although surgeons prefer to conduct OAGB procedure because of its easier surgical approach needing just one anastomosis formation it is not virtually clear that is the procedure costly benefitted regarding bile reflux outcomes.

Introduction: Percutaneous endoscopic gastrostomy (PEG) is the most common way of inserting a gastrostomy tube. If PEG is not appropriate for a patient, then the laparoscopic or open technique should be used. Here, we introduce a new laparoscopic technique for inserting a gastrostomy tube. Material and Surgical Technique: We used this new laparoscopic approach in 21 patients for whom PEG was not suitable. After marking on the abdominal skin and inserting the trocars, two 2-0 silk sutures were passed. Two stitches were placed 2 cm apart in the stomach with one hand. Each suture was pulled out with the fascia closure, the stomach was pulled out with a Babcock, and a purse-string suture using a round 2-0 silk suture was placed outside the stomach, creating a mushroom-retained gastrostomy. Conclusion: This new laparoscopic technique is minimally invasive. It provides full control through only two trocars and required smaller incisions than common laparoscopic approaches. This method can be used to insert a gastrostomy tube in indicated patients when PEG placement is not suitable.
