Introduction
Bariatric surgeries are currently the only effective treatment for morbid obesity and its associated comorbidities. However, 20% of patients fail to lose weight or regain weight after surgery. Banding of sleeve gastrectomy and Roux-en-Y gastric bypass had better results than their nonbanded counterparts. In this study, we aimed to study the effectiveness of banded mini-gastric bypass (BMGB) in BMI loss, resolution of comorbidities, and postoperative complications compared with mini-gastric bypass (MGB).
Patients and methods
From June 2018 to June 2021, we reviewed all medical records of patients of the Bariatric Surgery Department at Ain Shams University Hospital undergoing either MGB) or BMGB. We included all patients older than 18 years, and we excluded those who were younger than 18 years or older than 60, had previous bariatric or gastrointestinal surgery, had psychiatric contraindications, pregnancy, and had other medical reasons denying laparoscopy. Patients were followed up at 12, 24, and 36 months at clinics.
Results
A total of 60 patients were included: 30 underwent laparoscopic MGB and 30 underwent BMGB. Most of the participants were females (70%). During 36 months of follow-up, no patient was lost. After 3 years of follow-up, patients had no significant difference in BMI loss for MGB and BMGB at 12 months (MGB: 29.4 ± 2.4 vs. BMGB: 28.4 ± 2.6, =0.14) and 36 months (MGB: 24.7 ± 2.2 vs. BMGB: 24.2 ± 2.1, =0.34), respectively. Yet, a significant lower BMI is detected in the MGB group at 24 months of follow-up (MGB: 24.8 ± 1.3 vs. BMGB: 26 ± 2.2, =0.01). No significant difference is detected between both operations in resolution of preoperative comorbidities or postoperative complications.
Conclusion
BMGB is a safe and effective procedure for morbidly obese patients. Our study showed no difference between BMGB and MGB in BMI loss owing to short-term follow-up. Studies are needed to compare BMGB with other banded procedures.
