Abstract
Background: Although early laparoscopic cholecystectomy is widely performed for acute cholecystitis, the optimal timing of a cholecystectomy in clinically ill patients remains controversial. This study aims to determine the best practice for the patients presenting with acute cholecystitis focused on disease severity and comorbidities. Methods: An international multicentric retrospective observational study was conducted over a 2-year period. Patients were divided into four groups: Group A: primary cholecystectomy; Group B: cholecystectomy after gallbladder drainage; Group C: gallbladder drainage alone; and Group D: medical treatment alone. Results: The subjects of analyses were 5,329 patients. There were statistically significant differences in mortality rates between patients with Charlson comorbidity index (CCI) scores below and above 6 (P < 0.001). The shortest operative time was observed in Group A patients who underwent surgery 0–3 days after admission (P < 0.01). Multiple regression analysis revealed CCI and low body mass index <20 as predictive factors of 30-day mortality in Grade I+II patients. Also, jaundice, neurological dysfunction, and respiratory dysfunction were predictive factors of 30-day mortality in Grade III patients. In Grade III patients without predictive factors, there were no difference in mortality between Group A and Group B (0% vs. 0%), whereas Group A patients had higher mortality rates than that of Group B patients (9.3% vs. 0.0%) in cases with at least one predictive factor. Conclusion: Even patients with Grade III severity, primary cholecystectomy can be performed safely if they have no predictive factors of mortality. Gallbladder drainage may have a therapeutic role in subgroups with higher CCI or higher disease severity. ? 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery
