Laparoscopic Sleeve Gastrectomy Versus Laparoscopicmini-Gastric Bypass in Management of Morbid Obesity and its Comorbidities

Background: Laparoscopicmini-gastric bypass (MGBP) is gaining popularity among the bariatric procedures today and laparoscopic sleeve gastrectomy (SG) as a single-stage procedure fort he treatment of morbid obesity is becoming increasingly popular.

Patients and Method: Between October 2014 and July 2018, 100 obese patients were randomized, operated upon, and followed up for 24 months in Al Minia University Hospital. A total of 50 patients underwent SG, and 50 patients underwent MGBP. The mean BMI of all patients was 47.8±5.5kg/m² , their mean age was 30±8.3 years and 80% of them were female. Patients were followed up at 1, 3, 6, 9, 12,15,18,21 and 24 months.

Results: Age, sex, BMI, and comorbidities were equal. The mean operative time for SG was 86.9 ± 51.6 min and that for MGBP was 108.4 ± 41.8 min; the percentage of 1-year excess weight loss was similar (76.2±4.49% for SG and 80.3±8.3% for MGBP). The comorbidities were significantly improved after both procedures, except for type 2 diabetes mellitus, which showed a higher resolution rate after MGBP.

Conclusion: Laparoscopic SG regarding excess weight loss is comparable to laparoscopic MGBP in short-term follow-up (2 year) with less metabolic effect. Further long-term studies are needed.
