Laparoscopic mini-gastric bypass versus laparoscopic sleeve gastrectomy in metabolic surgery A single center experience.

AIM: The safety and effectiveness of MGB versus LSG remain unclear. In this study, we It has been shown by many clinical studies that laparoscopic sleeve gastrectomy (LSG) and mini-gastric bypass (MGB), two current methods in metabolic surgery, may be alternatives to Roux-en-Y gastric aimed to compare the postoperative outcomes of MGB and LSG procedures performed in bariatric surgery.

MATERIAL METHODS: A total of 175 patients who underwent MGB and LSG surgery between 2016 and 2018 at a single metabolic surgery center were analyzed retrospectively. Two surgical procedures were compared in terms of the perioperative, early and late postoperative outcomes.

RESULTS: There were 121 patients in the MGB group and 54 patients in the LSG group. No significant difference was found between the groups regarding the operating time, the conversion to open surgery and the early postoperative complications (p>0.05). The length of hospital stay was significantly shorter in the MGB group (p:0.001). The excess weight loss (EWL%) and total weight loss (TWL%) were significantly higher in the MGB group (90.3 vs. 79.2; and 36.4 vs 30.5, respectively). No significant difference was found between the two groups in terms of the remission rates of comorbidities. The symptoms of gastroesophageal reflux were observed in a significantly fewer number of the patients in the MGB group (6 patients 4.9% vs. 10 patients 18.5%).

CONCLUSIONS: Both LSG and MGB are effective, reliable, and useful methods in metabolic surgery. The MGB procedure is superior to the LSG in terms of the length of hospital stay, EWL%, TWL% and the postoperative gastroesophageal reflux symptoms.
