Effect of laparoscopic mini-gastric bypass versus laparoscopic sleeve gastrectomy on hypertension and dyslipidemia in obese type 2 diabetes mellitus patients

Objective: The aim of the research was to compare the effect of the laparoscopic mini-gastric bypass (LMGB) technique with the laparoscopic sleeve gastrectomy (LSG) technique in bariatric surgery on type 2 diabetes mellitus (T2DM), hypertension (HTN), and dyslipidemia in obese T2DM patients.Materials and methods: A prospective, cross-sectional study, conducted in Surgery Department at Al-Mouwasat and Al-Assad University Hospitals in Damascus, and included T2DM obese patients who would undergo bariatric surgery using the LMGB or LSG technique.Results: The research included two groups: the LSG group (92 patients, 60.9% female, age 44.6 year, BMI 41.85 kg/m2) and the LMGB group (137 patients, 59.1% female, age 47.1 year, BMI 43 kg/m2). Before surgery, the prevalence of HTN and dyslipidemia were similar in the two groups. After one year: T2DM improvement and remission rate in the LMGB group (13.9, 80.3%) were greater than in the LSG group (13, 62%), the difference was statistically significant. The HTN improvement and remission rate in the LMGB group (52.9, 41.4%) were greater than in the LSG group (47.5, 39%), the difference was not statistically significant. The dyslipidemia improvement rate was greater in LSG group (47.2 vs. 32.7%), while the dyslipidemia remission rate was greater in LMGB group (67.3 vs. 52.8%), the difference was statistically significant.Conclusions: The authors found that the LMGB technique was more effective than the LSG technique in controlling cardiovascular risk factors of obesity, T2DM, HTN, and dyslipidemia.
