EFFICACY OF LAPAROSCOPIC SLEEVE GASTRECTOMY ON TYPE 2 DIABETES WITH BMI LESS THAN 35: A RETROSPECTIVE STUDY

Objective: To evaluate the effectiveness of Laparoscopic Sleeve Gastrectomy (LSG) for resolving type 2 diabetes in patients with BMI >30 kg/m2. Methods: A retrospective study was conducted on 90 type 2 diabetic patients with BMI>30 kg/m2 who underwent LSG at Sunrise Hospital, Kochi, India, from September 2009 to February 2014. In this study, we compared preoperative parameters such as BMI, HbA1c and diabetic medications with postoperative parameters during periodic reviews. Results: Complete resolution of type 2 diabetes found in 86.6%, 91.1%, and 88.4% in patients with obese class I, II & III respectively. The complete resolution of diabetes (F=0.421, P=0.658) and drop in HbA1c (F=0.172, P=0.842) among the BMI groups were statistically not significant, i.e. class I obese patients were equally benefited compared to class II and class III obese patients. Co-morbidities also resolved to a good extent; sleep apnea 100%, fatty liver 89.47%, dyslipidemia 88.57%, polycystic ovarian disease 83.33% and hypertension 82.22%. Minor complications were reported in 3.84%, whereas no complications in 96.16% of the patients. Conclusion: Laparoscopic sleeve gastrectomy was found to be an effective intervention for obese type 2 diabetic patients, even when BMI is 30-34.9 kg/m2.
