Prevalence of gallbladder cancer In patients submitted to cholecystectomy: experience of the University Hospital, Faculty of Medical Sciences, State University of Campinas - UNICAMP.

OBJECTIVE

: to evaluate the prevalence of gallbladder carcinoma in patients submitted to cholecystectomy for chronic cholecystitis at the University Hospital of the State University of Campinas.

METHODS

: we conducted a retrospective prevalence study through the analysis of histological specimens from January 2010 to May 2015.

RESULTS

: we analyzed 893 patient reports. Emergency cholecystectomies amounted to 144, and elective ones, 749 (16.2% and 83.8%, respectively). Regarding gender, 72.8% were female and 27.2% male. Gallbladder adenocarcinoma occurred in 12 patients (1.3%) and non-Hodgkin's lymphoma in one (0.1%). In patients with cancer, seven (53.8%) were associated with cholelithiasis and two (15.3%) with gallbladder polyps.

CONCLUSION

: prevalence results of gallbladder adenocarcinoma in this study were similar to those of Western studies and the main risk factor was cholelithiasis, followed by the presence of gallbladder polyps.
