Gallbladder Polyp: Review and Proposed Algorithm for Management
1Gastroenterology Resident, Bombay Hospital & Medical Research Centre, Mumbai, Maharashtra.
Abstract:
Gall bladder polyp is a lesion which is often an incidentally reported finding on ultrasonography. Such patients may or may not have symptoms of gall bladder disease. Although majority of polyps are cholesterol polyps, some are malignant. The challenge is early detection of malignant polyp and cholecystectomy before it becomes invasive or if invasive to carry out adequately wide surgical excision; while avoiding surgery in asymptomatic patients with benign disease. Following are the characteristics suggestive of malignancy in polyp: - size more than 10 mm, solitary lesions, increase in size over time, adenomatous polyps, sessile lesions and associated gallbladder wall thickening. Incidence of malignancy is higher in patients with Indian ethnicity, age more than 50 years, associated primary sclerosing cholangitis or gall stone disease. Pre-operative tissue diagnosis is difficult to obtain and review ultrasonography, contrast enhanced CT scan, endo sonography and a regular follow-up can help the surgeon take the appropriate decision.
