title: Single-incision laparoscopic appendectomy versus conventional laparoscopy in adults. A systematic review.
abstract: OBJECTIVE
  To determine the best treatment option for not complicated acute appendicitis (AA) in adult patients, between single incision laparoscopy (SIL) and conventional laparoscopy (CL), measured by morbidity associated with disease.
  
  
  METHODS
  Systematic review. Articles of adults diagnosed with AA treated by SIL or CL were analyzed. Databases included: MEDLINE, LILACS, IBECS, Web of Science, Scopus and Cochrane, using MeSH terms and free words. The studies were analyzed using the MINCIR methodology. Variables included: conversion rate, morbidity, hospital stay, surgery duration, and methodological quality (MQ) of primary studies. Averages, medians and weighted averages were calculated.
  
  
  RESULTS
  Thirteen articles were analyzed. For SIL and CL the conversion rate were 3.4% and 0.7 %, the morbidity were 8% and 6.5%, the hospital stay were 2.5 and 2.8 days, the surgery duration were 53.4 and 53.8 minutes, and the MQ were 14.3±6.6 and 16.0±6.9 points, respectively.
  
  
  CONCLUSIONS
  With the exception of the conversion rate, there are no differences between single incision laparoscopy and conventional laparoscopy for the treatment of acute appendicitis in adults.
