Abstract
Introduction: Bariatric Surgery is known to cause resolution of comorbidities associated with obesity. While laparoscopic Roux-en-Y gastric bypass has well documented positive results on resolution of type 2 diabetes, there exists variable data regarding the effects of Laparoscopic Sleeve Gastrectomy on glycaemic control. We herein present our results on the impact of Laparoscopic Sleeve Gastrectomy on glycaemic control over 2 years.
Methods
A prospective study was undertaken on patients undergoing Laparoscopic Sleeve Gastrectomy for morbid obesity from October 2017 to February 2019. Patients with diabetes and prediabetes were included in the study. Data consisting of demography, anthropology and investigations were collected and analysed. The effect on the glycaemic profile was studied.
Results
Among the 44 obese patients, 14 were found to be prediabetic and 30 were diabetic. The mean HbA1c and FBS preoperatively was 7.74 % and 120.5 mg/dl respectively. Evaluation of postoperative glycaemic control for all diabetic patients showed that mean HbA1c changed from 7.74% preoperatively to 6.40%, 5.82%, 5.44%, and 5.32% at 3, 6, 12, and 24 months post LSG, respectively. Complete remission identified as Fasting Blood Glucose <100mg/dl, HbA1c < 6%, and off medications for at least 1 year after surgery was observed in 86.66 % (26/30) patients.
Conclusion
Laparoscopic Sleeve Gastrectomy seems to provide a promising effect on glycaemia along with reduction of intake of diabetic medications. Further long-term studies are needed to evaluate prolonged diabetic remission.
