Background And Aim: Acute acalculous cholecystitis (AAC) is an acute inflammatory disease of the gallbladder in the absence of cholecystolithiasis. It is a serious clinicopathologic entity, with a high mortality rate of 30-50%. A number of etiologies have been identified that can potentially trigger AAC. However, clinical evidence on its occurrence following COVID-19 remains scarce. We aim to evaluate the association between COVID-19 and AAC.
Methods: We report our clinical experience based on 3 patients who were diagnosed with AAC secondary to COVID-19. A systematic review of the MEDLINE, Google Scholar, Scopus, and Embase databases was conducted for English-only studies. The latest search date was December 20, 2022. Specific search terms were used regarding AAC and COVID-19, with all associated permutations. Articles that fulfilled the inclusion criteria were screened, and 23 studies were selected for a quantitative analysis.
Results: A total of 31 case reports (level of clinical evidence: IV) of AAC related to COVID-19 were included. The mean age of patients was 64.7 ± 14.8 years, with a male-to-female ratio of 2.1:1. Major clinical presentations included fever 18 (58.0%), abdominal pain 16 (51.6%), and cough 6 (19.3%). Hypertension 17 (54.8%), diabetes mellitus 5 (16.1%), and cardiac disease 5 (16.1%) were among the common comorbid conditions. COVID-19 pneumonia was encountered before, after, or concurrently with AAC in 17 (54.8%), 10 (32.2%), and 4 (12.9%) patients, respectively. Coagulopathy was noted in 9 (29.0%) patients. Imaging studies for AAC included computed tomography scan and ultrasonography in 21 (67.7%) and 8 (25.8%) cases, respectively. Based on the Tokyo Guidelines 2018 criteria for severity, 22 (70.9%) had grade II and 9 (29.0%) patients had grade I cholecystitis. Treatment included surgical intervention in 17 (54.8%), conservative management alone in 8 (25.8%), and percutaneous transhepatic gallbladder drainage in 6 (19.3%) patients. Clinical recovery was achieved in 29 (93.5%) patients. Gallbladder perforation was encountered as a sequela in 4 (12.9%) patients. The mortality rate in patients with AAC following COVID-19 was 6.5%.
Conclusions: We report AAC as an uncommon but important gastroenterological complication following COVID-19. Clinicians should remain vigilant for COVID-19 as a possible trigger of AAC. Early diagnosis and appropriate treatment can potentially save patients from morbidity and mortality.
Relevance For Patients: AAC can occur in association with COVID-19. If left undiagnosed, it may adversely impact the clinical course and outcomes of patients. Therefore, it should be considered among the differential diagnoses of the right upper abdominal pain in these patients. Gangrenous cholecystitis can often be encountered in this setting, necessitating an aggressive treatment approach. Our results point out the clinical importance of raising awareness about this biliary complication of COVID-19, which will aid in early diagnosis and appropriate clinical management.
