Single-incision laparoscopic appendectomy versus conventional laparoscopy in adults. A systematic review


Acta Cir. Bras.




PURPOSE: 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. CONCLUSION: 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.
