Cholecystectomy in patients with cirrhosis: a population-based cohort study from England.

ABSTRACT

BACKGROUND: This population-based cohort study aimed to determine postoperative outcomes after emergency and elective cholecystectomy in patients with cirrhosis. METHODS: Linked electronic healthcare data from England were used to identify all patients undergoing cholecystectomy between January 2000 and December 2017. Length of stay (LOS), re-admission, case fatality and the odds ratio of 90-day mortality were calculated for patients with and without cirrhosis, adjusting for age, sex and co-morbidity using logistic regression. RESULTS: Of the total 69,141 eligible patients who underwent a cholecystectomy, 511 (0.74%) had cirrhosis. In patients without cirrhosis 86.55% underwent a laparoscopic procedure compared with 57.53% in patients with cirrhosis (p < 0.0001). LOS was longer in those with cirrhosis (3 IQR 1-8 vs 1 IQR 1-3 days,p < 0.0001). 90-day re-admission was greater in patients with cirrhosis, 36.79% compared with 14.95% in those without cirrhosis. 90-day case fatality after elective cholecystectomy in patients with and without cirrhosis was 2.79% and 0.43%; and 12.82% and 2.39% following emergency cholecystectomy. This equated to a 3-fold (OR 3.22, IQR 1.72-6.02) and a 4-fold (OR 4.52, IQR 2.46-8.33) increased odds of death at 90-days following elective and emergency cholecystectomy after adjusting for confounders. CONCLUSION: Patients with cirrhosis undergoing cholecystectomy have an increased 90-day risk of postoperative mortality, which is significantly worse after emergency procedures.
