Surgery for hepatic hidatidosis. Risk factors and variables associated with postoperative morbidity. Overview of the existing evidence

Abstract

There are few publications related to postoperative morbidity in hepatic hydatidosis and these have mixed results. The aim of this study was to determine risk and protective factors of postoperative morbidity in patients operated on for hepatic hydatidosis. A comprehensive review was made of the evidence, based on systematic reviews, clinical analyses and observational studies, obtained from the Trip Database, BVS, SciELO, Cochrane Central Register of Controlled Trials, WoS, MEDLINE, EMBASE, SCOPUS, EBSCOhost, IBECS, ePORTUGUESe, LILACS and WHOLIS. 1,087 related articles were identified; 69 fulfilled the selection criteria (2 systematic reviews, 3 clinical trials and 64 observational studies). Age, history of previous surgery for hepatic hydatidosis, location in the hepatic center, existence of biliary communications and evolutionary complications of the cyst were identified as risk factors, and radical surgical techniques as protective factors. Risk and protective factors were identified; however, the studies are few and the quality moderate to low.
