Sleeve Gastrectomy with Braun Anastomosis Transit Bipartition (B-TB): a Potential Midway Between Single Anastomosis and Roux-en-Y Transit Bipartition.

Abstract

The single anastomosis sleeve ileal bypass (SASI) procedure is a simple modification of the Roux-en-Y transit bipartition (RYTB) procedure; however, SASI risks patients with possible biliary reflux. Braun anastomosis has been proposed to fix the biliary reflux of single anastomosis procedures. This study presented our early "sleeve gastrectomy with Braun anastomosis Transit Bipartition" (B-TB) outcomes. Patients who underwent B-TB or RYTB between June 2020 and April 2021 at our hospital and have completed three months follow-up were included in this study. Ten patients with B-TB and forty patients with RYTB were included. No significant differences were observed between the B-TB and RYTB patients regarding the preoperative conditions. The B-TB procedure had significantly shorter operation time and postoperative hospitalization time than the RYTB procedure. There was no significant difference between the two groups regarding the 3-month percentage of total weight loss (B-TB vs RYTB: 19.7 ± 2.7% vs 22.2 ± 5.4%) and the postoperative complications before discharge. Preoperatively, two patients and eight patients achieved GERD-Q score ≥8 for the B-TB and RYTB group, respectively. At postoperative 3 months, those with GERD-Q score ≥8 was reduced to one patient and two patients for the B-TB and RYTB group, respectively. No patients have reported symptoms of greenish-yellow vomiting in both groups postoperatively. B-TB is an exciting procedure with potential benefits. However, as it is an investigational procedure, extra care should be maintained. Larger samples and more extended follow-up data are needed in the future.
