Sleeve gastrectomy versus mini-gastric bypass and their effects on type II diabetes mellitus and weight loss outcome

Abstract

Bariatric surgeries such as sleeve gastrectomy; mini-gastric bypass surgery are successful weight reduction surgeries which significantly impact metabolic syn-drome. The purpose of this research was to assess the impact of laparoscopy gastrectomy and mini-gastric bypasses on weight decrease and diabetes remission of diabetic mellitus type 2 through two years of monitoring. Furthermore, this study looked at the difference between the two procedures regarding their efficacy and identify which one is proper for patients according to their comor-bidities. A prospective study was held in Al Sadder Medical City and Al-Gadeer private hospitals in Al-Najaf city, Iraq, from January 2016 to February 2018. The study included 35 obese and morbidly obese patients with a known history of diabetes mellitus type 2, diagnosed from at least two years before surgery. 15 patients undergo uneventful laparoscopic sleeve gastrectomy (6 females and 9 males). 20 patients underwent uneventful laparoscopic gastric mini bypass surgery (6 females and 14 males). In addition, the patients were followed in the short-term postoperatively (3, 6, 12, 24 months) by monitoring their BMI, weight loss, and HbA1c. There was a decrease in BMI of about 45% from the baseline BMI in sleeve gastrectomy surgery and a decrease in HbA1c of about 45%, less than 6%. In gastric mini-bypass surgery, there was a decrease in BMI of about 47% from the baseline BMI and a decrease in HbA1c of about 45% from the baseline less than 6%, during a 24-month monitoring. Both surgeries were fruitful and had efficient results on patients, but the gastric mini bypass was more efficient than sleeve gastrectomy in controlling and remission of DM type 2 without the need for medications. A long-term study should be performed to reveal their effect and benefits to the patients.
