Safety and Efficacy of Single Anastomosis Sleeve Ileal (SASI) Bypass Surgery on Obese Patients with Type II Diabetes Mellitus during a One-Year Follow-up Period: A Single Center Cohort Study.

BACKGROUND

We aimed to evaluate the safety and efficacy of single anastomosis sleeve ileal (SASI) bypass surgery on obese patients with type II diabetes mellitus during a one-year follow-up period.

METHODS

We included patients with a body mass index (BMI) more than 35 kg/m and at least one-year history of type II diabetes mellitus. We excluded patients aged under 25 or above 66 years, those who were not candidates for surgery, needed another bariatric surgery, and those not willing to participate in the study. All the patients were visited in the outpatient office on the 10 and 45 days as well as the 3 month of the post-operative period until the end of the first year.

RESULTS

in this study, we investigated 14 male (23.0%) and 47 female (77.0%) morbidly obese patients with type II diabetes mellitus who underwent SASI bypass. The mean excess weight loss (%EWL) was 60.99±15.69 and the mean total weight loss (%TWL) was 30.39±6.52 at the end of the one-year follow up. Finally, 44 patients (72.1%) had a complete and 15 patients (24.6%) had partial remission of type II diabetes mellitus. Of note, severe complications were recorded in two patients (3.2%). Paired test analysis demonstrated a significant decrease for fasting plasma sugar (FBS) after one-year follow-up in comparison with FBS before surgery (<0.0001). Furthermore, this difference was observed in HbA1c (<0.0001).

CONCLUSION

SASI bypass is an effective method for weight loss and controlling type II diabetes mellitus.
