Background. The aim of this study is to clarify the prevalence of gallbladder benign neoplasms, their ultrasonographic appearance and their relationship with gallbladder lithiasis and cancer.
Methods. This study was carried out on 9000 consecutive patients having ultrasound of upper abdomen. Only adenomas and papillomas are considered as true benign neoplasms of the gallbladder. Adenomiomatosis and cholesterol polyps, often erroneously labelled as benign neoplasms, were excluded. Patients were followed-up by ultrasound every three months up to two years.
Results. The prevalence of benign neoplasms was 1.19%. Papillomas were found more frequently than adenomas both in males (68.51%) and in females (94.33%). Gallstones were not concomitant with benign neoplasms in any case. Neither stones nor growth of gallbladder benign neoplasms were recorded within the two-year follow-up period.
Conclusions. Papillomas were more frequent than adenomas. No gallstone was concurrent with gallbladder benign neoplasms in our series. However, when gallstones are evidenced at ultrasound, further attention is recommended to discover probable concomitant neoplasms. Papillomas and adenomas more than 1 cm in diameter should be quarterly followed-up, while smaller masses could be six-monthly controlled. Surgery should be indicated for large-sized or rapidly growing masses because of the risk for cancer development.
