RESUMO
OBJECTIVE: The objective of this study was to determine the correct therapeutic management for patients with gallbladder polyps (GPs), what type of surveillance should be employed and how to differentiate between benign and malignant polyps in addition to also to providing reassurance in cases of "cancerophobia". STUDY DESIGN: This was a 5-years retrospective study. LOCATION: The study was conducted at a Surgery Department at the Hospitais da Universidade de Coimbra. POPULATION: We analyzed all patients operated on at the Surgery Service II from January 2003 to December 2007 who had had a preoperative diagnosis of GP. METHODS: Clinicopathological correlations were traced for all patients. The following were analyzed: demographic data, clinical presentation, principal symptoms, associated pathologies, supplementary tests and diagnoses. RESULTS: We studied 93 patients, 91 of whom had benign polyps and two of whom had malignant polyps. Of the 91 benign polyps, 73 (78.5%) were cholesterol polyps, 14 (15%) were hyperplastic and two (2.2%) were adenomas. Two (2.2%) patients had malignant polyps, both adenogallbladder carcinomas. The mean diameter of benign polyps was 6 mm and 40 (43%) patients had multiple lesions. The mean diameter of malignant and premalignant polyps taken together was 18.8 mm, all were single polyps and the mean age of this patient subset was 57.7 years. CONCLUSION: It was concluded that the surgical option for GPs is cholecystectomy and that this should only be undertaken in cases where there are clinical signs of GP; polyps with diameters greater than 10 mm; fast-growing polyps; sessile polyps or wide-based polyps; polyps with long pedicles; patient aged over 50; concurrent gallstones; polyps of the gallbladder infundibulum or abnormal gallbladder wall ultrasound.

OBJETIVO: O objetivo do estudo é saber qual a orientação terapêutica para os doentes com pólipos vesiculares (PVs), que tipo de vigilância realizar, saber diferenciar entre um pólipo benigno e um pólipo maligno e proporcionar uma tranquilização em relação à "cancrofobia". Tipo de estudo: Realizou-se um estudo retrospectivo de cinco anos. Local: O estudo foi realizado nos Hospitais da Universidade de Coimbra, num Serviço de Cirurgia. População: Foram estudados todos os doentes operados no Serviço de Cirurgia II com o diagnóstico pré-operatório de PV, entre janeiro de 2003 e dezembro 2007. MÉTODOS: Foi feita correlação clínico-patológica de todos os doentes. Feita avaliação: de dados demográficos, da apresentação clínica, dos principais sintomas, das patologias associadas e exames complementares de diagnóstico realizados. RESULTADOS: Foram estudados 93 doentes, sendo que em 91 doentes tratava-se de pólipos benignos e em dois doentes de pólipos malignos. Dos 91 pólipos benignos, 73 (78,5 por cento) eram pólipos de colesterol, 14 (15 por cento) hiperplasias e dois (2,2 por cento) adenomas. Em dois (2,2 por cento) doentes tratava-se de pólipos malignos, adenocarcinoma da vesícula biliar. O diâmetro médio dos pólipos benignos é de 6 mm, 40 (43 por cento) doentes apresentavam lesões múltiplas. Nos pólipos malignos e pré-malignos (adenomas) o diâmetro médio é de 18,8 mm, são todas lesões solitárias e a idade média destes doentes é de 57,7 anos. CONCLUSÃO: Conclui-se que o tratamento cirúrgico dos PVs é a colecistectomia e só deve ser realizado quando existe: clínica relacionada com o PV; pólipos de diâmetro superior a 10 mm; crescimento do pólipo num curto espaço de tempo; pólipo séssil ou base de inserção larga; pólipo com longo pedículo; idade do doente superior a 50 anos; coexistência de litíase vesicular; pólipos localizados no infundíbulo da vesícula ou alterações ecográficas na parede vesicular.
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 percent) patients had adenocarcinoma. Among benign polyps, 73 (78,5 percent) were cholesterol polyps, 14 (15 percent) were hyper-plastic and 2 (2.19 percent) were premalignant adenomas. Mean diameter of benign polyps, excluding adenomas, was 6 mm. In 40 (43 percent) 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.
