Aims  This meta-analysis aimed to define the perioperative risk of mortality in patients with alcoholic liver disease (ALD) undergoing extrahepatic gastrointestinal surgery.    Methods  Systematic searches of Embase, Medline and CENTRAL were undertaken to identify studies reporting about patients with ALD undergoing extrahepatic gastrointestinal surgery published since database inception to January 2019. Studies were only considered if they reported on mortality as an outcome. Pooled analysis of mortality was stratified as benign and malignant surgery and specific operative procedures where feasible.    Results  Of the 2899 studies identified, only five studies met inclusion criteria, representing cholecystectomy (one study), umbilical hernia repair surgery (one study) and oesophagectomy (three studies). The total number of patients with ALD in these studies was 172. Therefore, any study on liver disease patients undergoing extrahepatic surgery that crucially included a subset with alcohol aetiology was included as a secondary analysis even though they failed to stratify mortality by underlying aetiology. The total number of studies that met this expanded inclusion criteria was 62, reporting on 37,703 patients with liver disease of which 1735 (4.5%) had a definite diagnosis of ALD. Meta-analysis of proportions of in-hospital mortality in patients with ALD undergoing upper gastrointestinal cancer surgery (oesophagectomy) was 23% [95% confidence interval (CI) 14–35%, I2 = 0%]. In-hospital mortality following oesophagectomy in liver disease patients of all aetiologies was lower, 14% (95% CI 9–21%, I2 = 41.1%).    Conclusion  Postoperative in-hospital mortality is high in patients with liver disease and ALD in particular. However, the currently available evidence on ALD is limited and precludes definitive conclusions on postoperative mortality risk.
