Abstract
Background: With improvements in ultrasonography more polypoid lesions of the gallbladder (PLGs) are being detected. The management of these is controversial. Methods: The demographic, radiological and pathological data of 38 patients with ultrasonographically detected PLGs were reviewed. A Medline search for such lesions was performed and a review of the literature is presented. Results: Thirty-four patients underwent cholecystectomy and four were advised against or declined operation. Of the 34 who had cholecystectomy, 11 had macroscopic and histopathologically proven PLGs. Of these, seven had cholesterol polyps, two had adenomas, one had a carcinoid tumour and one had an adenocarcinoma of the gallbladder. One patient had a histopathologically normal gallbladder. The remainder had chronic cholecystitis with or without gallstones. All of the patients with neoplastic lesions of the gallbladder had solitary polyps greater than 1·0 cm in diameter. Conclusion: A protocol for the management of ultrasonographically detected PLGs is proposed. In this protocol it is suggested that patients with a PLG should undergo surgery if they are symptomatic, or if the PLG is 1·0 cm or more in diameter.
