The Complications of Bariatric Surgery Patients with Type 2 Diabetes in the World: A Systematic Review and Meta-Analysis

摘要

Background: In this Meta-analysis, we aimed to quantify the incidence of complications ofdifferent methods of bariatric surgery on diabetic patients.Introduction: Type 2 Diabetes Mellitus (T2DM) is increasing worldwide specifically in obese cases.Additionally, obesity worsens T2DM. Complications of each bariatric surgery method were assessedseparately; but, a meta-analysis of these complications and comparison between procedures in T2DMpatients have not been investigated previously. The result of this study will help surgeons to choose themost appropriate surgical technique, considering individual conditions for a diabetic patient.Methods: We searched PubMed, Scopus, and ISI for original papers including bariatric surgical proceduresfor diabetic population and the reported consequences. Data analyses were done using Stata software.Results: Mortality percentage between diabetic and non-diabetic patients was statistically nonsignificant(P = 0.987). Early and late complications were higher in diabetic group in comparison withnon-diabetic (6.0 vs. 1.8, P = 0.024 and 0.6 vs. 0.3, P = 0.04, respectively). Most prevalentfindings in malabsorptive (7.8, P < 0.001) and restrictive procedures (80, P < 0.001) were majorcomplications and hypoglycemic episodes, respectively.Conclusion: As our study showed, most of the complications are not necessarily higher in diabeticpopulation but dependent on the method of surgery.
