AIM:To investigate the preoperative factors that can predict neoplastic polypoid lesions of gallbladder (PLGs) as well malignant PLGs. METHODS:A retrospective analysis was conducted on 210 consecutively enrolled patients who underwent cholecystectomy due to a PLG larger than 10 mm, determined by trans-abdominal ultrasonography or endoscopic ultrasonography.We ana-lyzed medical, laboratory, radiologic data and pathologic results. RESULTS:In cases, 146 had non-neoplastic polyps (69.5%) 64...
Percutaneous cholecystostomy (PC) is an effective treatment for cholecystitis in high-risk surgical patients. However, there no definitive agreement on the need additional cholecystectomy these patients.All patients who were admitted to Cheju Halla General Hospital (Jeju, Korea) acute and underwent ultrasonography-guided PC between 2007 2012 consecutively enrolled this study.
