Laparoscopic Sleeve Gastrectomy With Transit Loop Bipartition and Transit Bipartition in Type 2 Diabetic Patients With Obesity: A Retrospective Analysis.

AIM

We aimed to compare 1-year postoperative results of patients with obesity and type 2 diabetes mellitus (T2DM) who underwent laparoscopic sleeve gastrectomy with transit bipartition (LSG-TB) and transit loop bipartition (LSG-TLB) and mini gastric bypass (MGB).

PATIENTS AND METHODS

This is a retrospective comparison of 2 novel bariatric surgery techniques with MGB. Primary outcome measure of the study was a rate of T2DM remission. Secondary outcomes included excess body mass index (BMI) loss, improvement in hepatosteatosis, and duration of operation. Revision surgery needs were also assessed.

RESULTS

Overall, 32 patients underwent the LSG-TLB, 15 underwent LSG-TB, and 50 underwent MGB. Mean age and sex distribution were comparable for all groups. Presurgical BMI was similar in MGB and LSG + TB groups, whereas LSG + TLB group had significantly lower BMI values compared with the MGB group. In both groups, BMI values reduced significantly compared with respective baseline values. Excess BMI loss was significantly higher in patients who underwent LSG-TLB compared with patients treated with LSG-TB and MGB. Bariatric surgery procedures lasted shorter in LSG-TLB than in LSG-TB. However, the shortest of all was MGB. The remission of T2DM rates were 71% and 73.3% in LSG-TLB and LSG-TB groups, respectively ( P > 9.999). The rate of revision surgeries was comparable in both groups.

CONCLUSION

In conclusion, LSG-TLB took less time and provided significantly higher excess BMI loss compared with LSG-TB. T2DM remission and improvement rates were similar in both groups. LSG-TLB seemed like a promising bariatric surgery technique in patients with obesity and T2DM.
