Simplified risk stratification in early cholecystectomy for acute cholecystitis based on age: A report from an institution with zero mortality

Abstract

AbstractBackground/PurposeThe existing risk stratification for early cholecystectomy in patients with acute cholecystitis (AC) is complex. This study aims to establish a simpler risk assessment for surgical complications after cholecystectomy based on age group.MethodsThis single‐center retrospective observational study enrolled 350 patients diagnosed with AC who underwent early cholecystectomy within 72 h of diagnosis from 2013 to 2021. Patients were divided into three subgroups based on age: young (<65 years), elderly (65–79 years), and very elderly (≥80 years). Since no mortality was observed, risk factors for the Clavien‐Dindo (CD) grade ≥ II complications were identified within the entire cohort and in each subgroup.ResultsThere were 120 young, 130 elderly, and 100 very elderly patients. The overall prevalence of complications with CD grade ≥ II was 11.1%. Age and Tokyo Guidelines 18 (TG18) severity were independent risk factors for surgical complications in the whole cohort. Subgroup analysis revealed that there was no independent risk factor in the young group. Meanwhile, age and poor physical status were independent risk factors in the elderly group, and TG18 severity in the very elderly group.ConclusionEvaluation of only age, physical status, and TG18 severity may be sufficient for risk stratification of surgical complications of AC.
