Colorectal Surgery in Patients with Liver Cirrhosis: A Systematic Review

Abstract

AbstractBackgroundColorectal surgery in patients with liver cirrhosis poses a significant challenge due to the associated peri‐operative morbidity and mortality risks. The aim of this systematic review was to evaluate the outcomes in this cohort of patients following colorectal surgery.MethodsThe PubMed, Embase and Cochrane databases and references were searched up to October 2022 using the PRISMA guidelines. The data collated included: patient demographics, pathology or type of colorectal operation performed, severity of liver cirrhosis, post‐operative complication rates, mortality rates and prognostic factors. A quality assessment of included studies was performed with the Newcastle–Ottawa scale.ResultsSixteen studies reporting the outcomes of colorectal surgery in patients with liver cirrhosis were identified, including the results of 8646 patients. The indications, pathologies and/or type of operations varied. The overall complication rate ranged from 29 to 75%, minor complication ranged 14.5–37% and major complication ranged 6.7–59.3%. The mortality rates ranged from 0 to 37%.ConclusionColorectal surgery in patients with liver cirrhosis still carries considerable morbidity and mortality rates. This group of patients needs to be managed in a multidisciplinary setting to achieve excellent outcomes. Future research should focus on uniform definitions to enable interpretable outcomes.
