Analysis of Predictive Factors for the Efficacy of Modified Three-Port Laparoscopic Sleeve Gastrectomy in Treating Type 2 Diabetes Mellitus.

OBJECTIVE

This retrospective cohort study identified predictors of treatment efficacy for modified three-port laparoscopic sleeve gastrectomy (TPLSG) in managing type 2 diabetes mellitus (T2DM).

METHODS

We retrospectively analyzed clinical data from 187 T2DM patientswho underwent modified TPLSG. Patients were categorized into effective group (those with satisfactory weight loss and diabetes remission/improvement) and ineffective group [those with insufficient weight loss and/or inadequate glycemic control (including patients meeting either or both criteria)]. After comparing baseline characteristics between groups, we performed regression analysis on significantly different variables to identify factors influencing treatment outcomes. A predictive nomogram was constructed and validated using calibration curves to assess the clinical value of these factors in predicting TPLSG efficacy for T2DM.

RESULTS

This study conducted a total inclusion of 187 T2DM patients who were grouped according to whether they performed effective or ineffective after treatment with modified TPLSG. 131 were included in the effective group and 56 in the other group. In respects of baseline C-peptide level, duration of diabetes, baseline triacylglycerol (TG) level, baseline homeostasis model assessment of insulin resistance (HOMA-IR) and baseline glycated hemoglobin (HbAlc) levels, the two groups displayed statistical significance (P < 0.05). Covariance analysis and regression equations for above factors revealed that none of them were covariate (VIF ≤ 10, tolerance ≥ 0.1) and all of them were influential factors leading to poor treatment effect after modified TPLSG, it was found that the mentioned factors boasted high application value in predicting the efficacy of patients after modified TPLSG by nomogram and calibration curves.

CONCLUSION

Baseline C-peptide level, duration of diabetes, baseline TG, baseline HOMA-IR, and baseline HbAlc level were all relevant factors affecting the treatment effect of patients with T2DM treated with modified TPLSG, which should be focused on and interfered in a targeted way in actual clinical practice.
