Long-limb length difference had no effect on outcomes of laparoscopic Roux-en-Y gastric bypass surgery for obese Chinese patients with type 2 diabetes mellitus: A CONSORT compliant article

Bariatric surgery is effective in treating different components of metabolic syndrome including obesity, type 2 diabetes mellitus (T2DM), and hyperlipidemia. But there is no consensus on the ideal biliopancreatic and Roux limb length. This study aimed to explore the effect of biliopancreatic limb and Roux limb lengths during laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures on weight loss and T2DM control. We studied the clinical records of 58 patients with metabolic syndrome, T2DM, and body mass index (BMI) 32 to 50 kg/m(2) who underwent LRYGB in our hospital. The short limb group (Group A) underwent LRYGB with a limb length of 160 to 200 cm (n = 31) and the long limb group (Group B) underwent LRYGB with a limb length of 210 to 240 cm (n = 27) were compared. The occurrence of acute or chronic internal hernia in Group B was higher than that in Group A (P = .026). Twelve months after surgery, patients from the 2 groups were also observed with reduction in BMI, percent excess weight loss (EWL), preoperative FPG, and HbA1c as compared with these indicators before surgery. However, the differences of these indicators between 2 groups were not significant at the time point of before and 3, 6, 12 months after surgery. LRYGB had significant effects on weight loss and diabetes control in obese T2DM patients. However, there was no significant difference in the short term on weight loss and diabetes control in the patients receiving different limb lengths.
