Descrição
OBJECTIVE: Appropriate treatment and timing hinge on whether the lesion is benign or malignant. Study: A five years retrospective descriptive analysis was performed. Location : Department of General Surgery in Hospitals of the University of Coimbra. Patients: We present a series of 93 consecutive patients who had elective surgery for known gallbladder polyps, treated from January 2003 to December 2007.
METHODS: An analysis was performed using clinical and radiological files of patients electively treated for gallbladder polyp. Ninety-three consecutive patients were evaluated, treated and followed in a Department of General Surgery in a Central Hospital in that period. Biographic, clinical and radiological data were compiled.
RESULTS: In 91 patients a benign lesion was found. Two (2.16%) patients had adenocarcinoma. Among benign polyps, 73 (78,5%) were cholesterol polyps, 14 (15%) were hyper-plastic and 2 (2.19%) were premalignant adenomas. Mean diameter of benign polyps, excluding adenomas, was 6 mm. In 40 (43%) patients, multiple lesions were found. The mean diameter in the subset of malignant and premalignant polyps was 18.8 mm, in all instances these were found to be single lesions; and mean age at presentation was 57,7 years.
CONCLUSION: Cholecystectomy is the appropriate surgical treatment for gallbladder polyps, when removal is warranted. Patients benefitting from surgery are those who are symptomatic, whose polyps exceed 10 mm in diameter and , have shown to be enlarging, to be sessile or broad-based, to have long pedicles;and also have . infundibular polyps, coexisting gallstones or changes on the gallbladder wall appearance at ultrasonography
