Abstract
Objective:
The aim of this study was to compare the results of the Roux-en-Y gastric bypass (RYGB) and mini-gastric bypass (MGB) regarding postoperative gastro-esophageal reflux disease (GERD), as well as safety and efficacy.
Patients and Methods:
This prospective study included 60 morbidly obese adults scheduled for bariatric surgery, randomly divided into two groups according to the type of bariatric procedure; MGB (n = 30) and RYGB group (n = 30). GERD symptoms were recorded using the GERD score questionnaire. Follow-up included evaluation of weight loss and GERD, upper gasrointestinal endoscopy to assess biliary reflux, and condition of the stomach and esophagus.
Results:
The operative time was significantly longer in RYGB group compared to MGB group (p < 0.001). The percentage of excess weight loss was slightly higher in the MGB group after 6 months (p = 0.096). There were no cases of leakage or mortalities in the two groups. Complications were recorded in 30% of the MGB group and 40% of the RYGB group. Biliary reflux was detected endoscopically in 11 patients (36.6%) in the MGB group and none of the RYGB group. GERD symptoms were exaggerated in MGB group after 1 month compared to RYGB group (p = 0.008). At 12 months, symptoms improved significantly in the two groups; the scores were nonsignificantly higher in MGB group (p = 0.088). Esophagitis was more common in the MGB group than RYGB group (p = 0.008).
Conclusion:
Laparoscopic Roux-en-Y gastric bypass and laparoscopic mini-gastric bypass appear to be equally effective in the treatment of morbid obesity regarding weight loss and resolution of obesity-related metabolic complications. On short-term follow-up, MGB exaggerated GERD symptoms, but in the long run, symptoms decreased markedly.
