Laparoscopic One-Anastomosis Gastric Bypass; Examine the Effectiveness and Outcomes in Patients with Morbid Obesity

Aim: To examine the effectiveness and outcomes of laparoscopic one-anastomosis gastric bypass surgery in patients presented with morbid obesity. Study Design: Prospective/Observational Place & Duration: Hayatwali Medical Center Asghar Mall Road, Rawalpindi, during from 1st June 2019 to 31st May 2020. Materials and Methods: Total 60 patients of both genders presented with morbid obesity with ages 20 to 65 years were enrolled in this study. Patients detailed demographics/medical history and co-morbidities were recorded after taking written consent. All patients received laparoscopic one-anastomosis gastric bypass (mini gastric bypass). Outcomes in term of weight loss, reduce in BMI and complications were examined. Patients satisfaction was also examined. Follow-up was taken at 6 months and at 1 year post-operatively. Data was analyzed by SPSS 24.0. Results: Out of 60 patients 25 (41.67%) were male while 58.33% were females with mean age 42.26 +/- 12.56 years.Diabetes mellitus was the most frequent comorbidity found in 30 (50%) patients. Mean surgery duration was 101.42 +/- 10.45 minutes. Mean hospital stay was 2.02 +/- 0.65 days. No postoperative complication was found. Mean BMI decrease 42.46 +/- 5.85 kg/m(2) to 25.8 +/- 4.67 kg/m(2) at 1 year. A significant decrease in weight loss was observed at 6 months postoperatively (preoperatively mean weight 148.45 +/- 25.4 kg vs postoperatively 75.43 +/- 8.64 kg) p-value <0.001 and at 1 year mean weight was 66.36 +/- 10.84 kg (p=<0.0001). Maximum decrease in weight and BMI was observed at 1 year. %EWL at postoperative 6 month was 64.72 +/- 14.24% and at 1 year it was 71.52 +/- 10.45%. Conclusion: It is concluded that laparoscopic one-anastomosis gastric bypass is very effective procedure for reducing weight in patients with morbid obesity with no major complications and higher patients' satisfaction.
