Abstract
BackgroundRoux-en-Y gastric bypass (RYGB) is one of the most effective bariatric procedures. The study aimed to explore the value of lengthening the biliopancreatic limb (BPL) in RYGB compared to the outcome of one-anastomosis gastric bypass (OAGB). MethodsThis prospective study included morbidly obese patients divided into two groups. The RYGB group (n = 36) was subjected to long biliary limb Roux-en-Y gastric bypass (LPRYGB), and the OAGB Group (n = 36) had one anastomosis gastric bypass. During follow-up, weight, BMI, percentage of excess body weight loss (%EBWL), resolution of obesity-related comorbidities, and quality of life (QoL) were evaluated.ResultsThere was no significant difference in weight and BMI after 3 and 6 months. At 12-month follow-up, weight loss was significantly higher in the OAGB group. After 12 months, the two groups showed significant improvement of comorbid conditions without significant difference between the two groups. The Qol was significantly higher in the LPRYGB group 3, 6, and 12 months after surgery compared to the OAGB group.ConclusionsExtending the BPL length in RYGB to 150 cm is as effective as OAGB in remission of comorbidities, including diabetes. It was also equally effective in weight reduction in the short term. OAGB was more efficient in weight reduction and a significantly faster operation. LPRYGB showed a better QoL of life 1 year after surgery.Graphical abstract
Highlights
The prevalence of obesity continues to rise unrelentingly
This study aimed to explore if lengthening the biliopancreatic limb (BPL) in Roux-en-Y gastric bypass (RYGB) can attain a better outcome in morbidly obese patients
We compared the effect of this modified RYGB with one-anastomosis gastric bypass (OAGB), which has been shown to be superior in weight loss and remission of comorbidities
Summary
The prevalence of obesity continues to rise unrelentingly. Its prevalence varies by country ranging from 3.7 to 38.2% [1]. The study aimed to explore the value of lengthening the biliopancreatic limb (BPL) in RYGB compared to the outcome of one-anastomosis gastric bypass (OAGB). The RYGB group (n = 36) was subjected to long biliary limb Roux-en-Y gastric bypass (LPRYGB), and the OAGB Group (n = 36) had one anastomosis gastric bypass. At 12-month follow-up, weight loss was significantly higher in the OAGB group. The Qol was significantly higher in the LPRYGB group 3, 6, and 12 months after surgery compared to the OAGB group. Conclusions Extending the BPL length in RYGB to 150 cm is as effective as OAGB in remission of comorbidities, including diabetes. It was effective in weight reduction in the short term. LPRYGB showed a better QoL of life 1 year after surgery
