Acute cholecystitis treated with urgent cholecystectomy achieves higher rate of critical view of safety when compared to interval cholecystectomy after tube cholecystostomy

Background There are few reported outcomes of treatment of acute cholecystitis incorporating current guidelines for gallbladder dissection techniques and use of percutaneous tube cholecystostomy (PCT). The authors hypothesize PCT allows regression of peritoneal inflammation, but infundibular inflammation is increased at interval cholecystectomy, resulting in greater requirement for advanced dissection techniques. Methods Between December 2009 and July 2023, 1222 patients were admitted with acute cholecystitis and ultimately underwent cholecystectomy. Of these 1222 patients, there were 876 patients that underwent urgent (within 10 days) cholecystectomy (UrgSurg), 170 patients underwent interval cholecystectomy (10 or more days) after antibiotic therapy (IntMed), and 175 patients that underwent PCT and interval cholecystectomy (IntTube). Minimally invasive operation was attempted in all patients.<br /> Patient demographics, comorbidities, surgical techniques (Critical View of Safety (CVS), infundibulum down, fundus-down, subtotal fenestrating, subtotal reconstituting, and conversion to open operation), and surgical outcomes were reviewed retrospectively. Multivariate logistic regression was performed to identify if interval cholecystectomy was independently associated with more advanced dissection techniques or reinterventions. Results Compared to the UrgSurg and IntMed patients, IntTube patients were significantly older (Median: 60 vs 66 vs 68, P < 0.001) and more often male (41.7% vs 47.6% vs 72.2%, P < 0.001). Additionally, IntTube patients were more likely to have medical comorbidities. Establishment of CVS was significantly less frequent in IntTube patients (61%) compared to UrgSurg patients (86%) and IntMed patients (85.9%) in unadjusted analysis (OR 0.26, P < 0.001) and in multivariable analysis after adjusting for potential confounders (OR 0.31, P < 0.001). There was no incidence of biliary injury, and no difference in rates of biliary reintervention among groups. Conclusion Interval Cholecystectomy after PCT is independently associated with a lower rate of achieving CVS, and higher rate of requirement for advanced cholecystectomy dissection techniques. We report a low rate of complications using current guidelines for minimally invasive surgery for both urgent and interval cholecystectomy for acute cholecystitis.
