title: Single anastomosis or mini-gastric bypass: long-term results and quality of life after a 5-year follow-up.
abstract: BACKGROUND
  Laparoscopic mini-gastric bypass (LMGB) is an alternative to the laparoscopic Roux-en-Y gastric bypass (LRYGB), which is considered to be the gold standard in the treatment of morbid obesity.
  
  
  OBJECTIVE
  Present 5-year results of 175 patients who had undergone a LMGB between October 2006 and October 2008.
  
  
  METHODS
  University public hospital, France.
  
  
  METHODS
  Complete follow-up was available in 126 of 175 patients (72%) who had LMGB. Mortality, morbidity, weight loss, co-morbidities, and quality of life were assessed. Weight loss was determined as a change in body mass index (BMI) and percent excess BMI loss (%EBMIL). Quality of life in the treatment group was analyzed using the Gastrointestinal Quality of Life Index (GIQLI) and was compared with a retrospectively case matched preoperative control group.
  
  
  RESULTS
  There were no deaths. Thirteen patients (10.3%) developed major complications. Marginal ulcers occurred in 4% of patients. Incapacitating biliary reflux developed in 2 (1.6%) who required conversion into RYGB. Gastric pouch dilation occurred in 4 patients (3.2%) and inadequate weight loss with severe malnutrition in 2 (1.6%). At 5 years, mean BMI was 31±6 kg/m(2) and mean %EBMIL was 71.5%±26.5%. Postoperative GIQLI score of the treatment group was significantly higher than preoperative score of the control group (110.3±17.4 versus 92.5±15.9, P<.001). Social, psychological, and physical functions were increased significantly. No significant differences were found in gastroesophageal reflux or diarrhea symptoms between the 2 groups. Long-term follow-up showed an improvement in all co-morbidities.
  
  
  CONCLUSIONS
  At 5 years, LMGB was safe, effective, and provided interesting quality of life results.
