Clinical Significances of Chronic Cholecystitis according to Gallbladder Contraction / 대한췌담도학회지

ABSTRACT

BACKGROUND/AIMS: Chronic cholecystitis and contraction of gallbladder (GB) have been regarded as precancerous lesions. The aim of study is to clarify whether chronic cholecystitis and GB contraction have clinical significance. METHODS: This study included 409 patients underwent cholecystectomy for chronic cholecystitis between January 2006 and June 2011 at a single center. Data regarding radiologic findings and blood tests were collected retrospectively. RESULTS: About 384 patients (94%) had GB stones. Among 409 patients, 104 (25.4%) patients had contracted GB and 305 (74.6%) patients did not. Biliary pain was more common in the contracted GB group (42.3% vs. 31.1%). The contracted GB group had a higher proportion of diffuse wall thickening type and a higher conversion rate to open cholecystectomy. Only seven patients (1.7%) were finally diagnosed with GB cancers. All patients were over 60 years of age and complained of biliary pain; however, only one patient had contraction of GB. CONCLUSIONS: Biliary pain, diffuse wall thickening, and conversion to open cholecystectomy were more frequent in the contracted GB group. Although incidental GB cancers were rarely diagnosed, all were older and had biliary pain. These will be used as significant evidences when making a treatment plan in chronic cholecystitis and contracted GB.
