In this study, 432 patients of acute acalculous cholecystitis were collected. According to the Tokyo guidelines severity grade, 167, 202, and 63 cases were classified as Grade I, II, and III, respectively. Eleven patients died and myocardial infarction/congestive heart failure was the only independent risk factor for in-hospital death. Cholecystectomy, especially the laparoscopic approach, had more preferable outcomes compared to their counterparts.

Patients with acute acalculous cholecystitis who were treated in Tohoku University and 41 board-certified hospitals of the Japanese Society for Abdominal Emergency Medicine, between January 2018 and December 2020.
We performed a questionnaire survey of acute acalculous cholecystitis and reviewed accumulated data from our institution and 41 board-certified hospitals in the Japanese Society for Abdominal Emergency Medicine. The questionnaire was framed to ask for detailed data on AAC cases and the number of AC patients who were treated from January 2018 to December 2020. Anonymous data collection was guaranteed by the study protocol, and opt-out method of informed consent were also used.
None
Collected data on patient characteristics, diagnosis, and treatment are described below; patient characteristics included age, sex, height, body weight, comorbidity by the Charlson comorbidity index (CCI), use of anticoagulant, and American Society of Anesthesiologists physical status (ASA-PS); disease-related variables included date of onset, medical condition and comorbidity before treatment, body temperature, laboratory data (e.g. white blood cell (WBC), C-reactive protein (CRP), total bilirubin), and bile cultures; treatment-related factors included date of initial treatment and cholecystectomy, date of discharge, methods of treatment, the procedure of cholecystectomy, operation time, intraoperative blood loss, and need for conversion; post-treatment outcomes included prognosis, complications, mortality, length of hospital stay, and recurrence of AC within 90 days after discharge.

This observational study examines not only the frequency of acalculous acute cholecystitis in Japan, but also the correlation between prognosis and background factors, severity of cholecystitis, and treatment.
