Laparoscopic Ileal Interposition with Diverted Sleeve Gastrectomy Versus Laparoscopic Transit Bipartition with Sleeve Gastrectomy for Better Glycemic Outcomes in T2DM Patients.

ABSTRACT

BACKGROUND: Metabolic procedures provide better outcomes for obese patients with type 2 diabetes mellitus. Our aim was to compare the glycemic regulation in patients that have undergone the laparoscopic ileal interposition with diverted sleeve gastrectomy (II-DSG), laparoscopic transit bipartition with sleeve gastrectomy (TB-SG), and laparoscopic sleeve gastrectomy (LSG) throughout a 12-month follow-up period retrospectively. METHODS: This study considered patients with T2DM who underwent metabolic procedures. The postoperative changes in the glucose, C-peptide, HbA1c, HOMA-IR, insulin, cholesterol, body mass index, and total weight loss (TWL) were compared retrospectively. The intended outcome was to reach a long lasting fasting blood glucose (FBG) <126 mg/dl. A multivariate regression analysis was applied to define the predictive markers in glucose regulation. RESULTS: Present study consisted of 83 patients with a mean age of 47.25 ± 6.58 years, mean preoperative BMI of 37.36 ± 2.71 kg/m2, and mean outcomes in the HbA1C and FBG of 9.05 ± 1.33% and 237 ± 15 mg/dl, respectively. There were similar correlations in BMI and total weight loss (TWL). At 12-month follow up period, compared to LSG group, TB-SG and II-DSG groups have higher remission proportions (35.3, 67.9, 54.7, respectively, p < 0.05) with similar TWL% (22.35, 27.14, 23.16%) outcomes. The II-DSG and TB-SG results drew closer together toward the end of this study interval unlike the LSG group. CONCLUSION: Our results showed that II-DSG and TB-SG ensured significant regression rates during the follow-up period. Since the TB-SG achieved these outcomes by finite anastomoses and intervening segments, it was considered to be a superior procedure compared to II-DSG and LSG procedures.
