Is conservative management a safe approach for patients with acute acalculous cholecystitis presenting with an acute abdomen?

Abstract

Patients with acute acalculous cholecystitis (AAC) often present with acute abdominal symptoms. However, recent clinical studies have suggested that some patients with AAC and an acute abdomen, especially when caused by viruses or rheumatic disease, may not require cholecystectomy and that conservative treatment is adequate. Whether cholecystectomy is superior to conservative treatment for patients with AAC presenting with a severe acute abdomen is still uncertain. This was a case series study of AAC-related literature published between 1960 and 2022. In total, 171 cases (104 viral infection-associated AAC and 67 rheumatic disease-associated AAC) were included. The prognoses of patients receiving cholecystectomy or conservative treatment were compared. To account for confounding factors, etiological stratification and logistic regression were performed. The prognosis was similar for patients undergoing cholecystectomy and conservative treatment (P value.364), and virus infection-associated AAC had a better prognosis than rheumatic disease-associated AAC (P value.032). In patients with AAC caused by viruses or rheumatic disease, the acute abdomen can be adequately managed by conservative treatment of the underlying etiology and does not mandate surgical intervention.
