title: Efficacy and safety of laparoscopic mini gastric bypass. A systematic review.
abstract: BACKGROUND
  Laparoscopic mini-gastric bypass (LMGB) is a relatively new bariatric procedure; published studies are accumulating in various settings. The objective of this study was to summarize the available evidence about the efficacy and safety of LMGB.
  
  
  METHODS
  A systematic search in the literature was performed , and PubMed and reference lists were scrutinized (end-of-search date: July 15, 2013). For the assessment of the eligible articles, the Newcastle-Ottawa quality assessment scale was used.
  
  
  RESULTS
  Ten eligible studies were included in this study, reporting data on 4,899 patients. According to all included studies, LMGB induced substantial weight and body mass index reduction, as well as substantial excess weight loss. Moreover, resolution or improvement in all major associated medical illnesses and improvement in overall Gastrointestinal Quality of Life Index score were recorded. Major bleeding and anastomotic ulcer were the most commonly reported complications. Readmission rate ranged from 0%- 11%, whereas the rate of revision operations ranged from .3%- 6%. The latter were conducted due to a variety of medical reasons such as inadequate or excessive weight loss, malnutrition, and upper gastrointestinal bleeding. Finally, the mortality rate ranged between 0% and .5% among primary LMGB procedures.
  
  
  CONCLUSIONS
  LMGB represents an effective bariatric procedure; its safety and minimal postoperative morbidity seem remarkable. Randomized comparative studies seem mandatory for the further evaluation of LMGB.
