Efficiency and risks of laparoscopic conversion of omega anastomosis gastric bypass to Roux-en-Y gastric bypass

Conversion from mini bypass to laparoscopic Roux en Y gastric bypass in an emergency setting: Case report and literature review

“…8 of them presented marginal ulcer refractory to treatment, and one of them presented an emergency due to perforation at the ulcer site. No postoperative mortality was reported [ 17 ].…”

Indications, Operative Techniques, and Outcomes for Revisional Operation Following Mini-Gastric Bypass-One Anastomosis Gastric Bypass: a Systematic Review

“…Bolckmans et al [10] described three different techniques of conversion to RYGB in their retrospective study of 27 patients. The first technique, like in the Lee study [11], involved a conversion to RYGB by dividing the biliopancreatic limb proximal to the GJ anastomosis ( Fig.…”

“…Poghosyan et al [13] reported a total of 17 patients undergoing revision to RYGB. They described their technique of resecting the distal portion of the gastric pouch as well as the GJ anastomosis with linear staplers, similar to the third technique described in the study by Bolckmans et al [10]. However, they used a circular stapler to create the new GJ anastomosis.…”

“…Due to a lack of an isolated biliopancreatic limb in MGB-OAGB, surgeons have theorized that patients would be more likely to experience intractable bile reflux as well as marginal ulcers. The reported revision rate ranged from 2 to 5% in patients undergoing MGB-OAGB [9][10][11]. In this study, we aimed to conduct a comprehensive literature review on the indications, operative techniques, and outcomes of revisional surgery following MGB-OAGB.…”

A Rocambolesque Metafiction

“…Seven had malnutrition, and two of those had to be converted to RYGB due to encephalopathy and/or severe malnutrition, with additional two patients with severe symptomatic biliary reflux. Recent reports attest to these kinds of conversions and or reversals [3,4]. Gastroscopies performed at 2 years had revealed 4 times more gastritis in OAGB, 3 times more esophagitis, with 2 cases of dysplasia, 1 gastric and 1 esophageal, none in RYGB.…”
