Weight loss, glycolipid profile changes in type 2 diabetes patients after esophagectomy: a propensity score matching analysis.

Abstract

Type 2 diabetes mellitus (T2DM) is a common co-morbidity in patients who receive esophagectomy and has unfavorable effects on glucose and lipid metabolism in patients. This study examines how weight and glycolipid metabolism change in patients with T2DM following esophagectomy. This retrospective, one-center, observational analysis with a propensity score matching analysis (PSM) included 114 patients who underwent esophageal surgery in the Department of Cardiothoracic Surgery, the 900th Hospital of Joint Logistic Support Force from 2017 to 2020, which were separated into T2DM group and Non-T2DM group. Weight, body mass index (BMI), fasting plasma glucose (FPG), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured and analyzed before and after the operation. Two groups showed similar reductions in weight and BMI after surgery. In the T2DM group, weight decreased from 63.10(10.31) before surgery to 55.10(11.60) kg at 6months (P < 0.001) with BMI decreasing from 22.67 (2.90) to 19.77 (3.48); While in the Non-T2DM group, weight decreased from 61.42 (8.46) to 53.19 (9.26) kg at 6months after surgery with BMI decline from 22.49 (2.77) before operation to 19.45 (3.08) at 6months after surgery. Fasting plasma glucose levels showed a significant decrease (P = 0.035) in the T2DM group at a six-month point of 7.00 (2.21) mmol/L compared to preoperative levels of 7.67 (2.32) mmol/L. HDL levels increased significantly in the Non-T2DM group at six months postoperatively at 1.52 (0.05) with P < 0.001 compared to preoperative levels of 1.22(0.04) mmol/L. TG, LDL, and TC levels decreased significantly in both groups from the preoperative to the 6-month point. Esophagectomy induces weight loss in T2DM and Non-T2DM groups, improves long-term glucose metabolism in the T2DM group, and enhances lipid metabolism in both groups. Further research is needed to understand their mechanisms.
