Gallbladder cancer and dysplasia in cholecystectomy specimens: A large study in high-incidence regions of South America.

Background And Aims: Gallstone disease has been causally linked to gallbladder cancer (GBC) via the carcinogenesis model of gallstones and inflammation leading to gallbladder dysplasia then GBC". Efficient GBC prevention through cholecystectomy requires accurate prediction of individual GBC risk, especially in low- and middle-income regions, where studies tend to be small and of low quality, and where financial and surgical capacity are limited.

Methods: In a collaborative study from high GBC incidence regions of Argentina, Bolivia, Chile and Peru, we collected and validated clinical information from 10,561 patients with gallstone disease who underwent cholecystectomy.

Totally Laparoscopic Radical Resection of Gallbladder Cancer: Technical Aspects and Long-Term Results.

Introduction: Gallbladder cancer (GBC) is a rare tumor in developed countries. Chile has one of the highest incidences worldwide. For patients affected by resectable T1b or more advanced GBC, radical cholecystectomy (RC) is considered the standard therapy.

Experience with the surgical treatment of hepatic hydatidosis: case series with follow-up.

Aim: To describe patient characteristics and the results of surgical treatment for hepatic hydatidosis (HH) in the Hospital Hernán Henríquez Aravena from December 2001 to March 2005.

Methods: Subjects older than 16 years with suspected HH were included based on the clinical picture and radiological studies. Variables examined included clinical and laboratory aspects, outcome, features of the parasite and surgical aspects.
