2 (1,8%) patients. There were 4 (3,6%) abscesses and 2 (1,8%) fistulas post PC. Drain dislodgment was found without sequelae in 8 (7,2%) patients. Elective cholecystectomy was performed in 35/111 (31,5%). Fifty-one of 87 (58,6%) patients with gallstones underwent cholecystectomy; 36/87 (41,3%) did not undergo surgery due to a too short follow-up or death of nonbiliary disease. In the AAC group, there was no recurrent cholecystitis in 17/24 (70,8%) patients; 3/24 (12,5%) underwent surgery and 4/24 (16,6%) patients died in the ICU. Conclusion: PC is a minimally invasive treatment with low complication rate for patients with acute cholecystitis whom considered being at high-risk for urgent cholecystectomy. Good selection (ASA III and IV) and indication is needed in patients with ACC before PC because the majority will be operated later on. AAC can be managed nonoperatively and further treatment might not be needed.
