Gallbladder cancer: Does bile contamination affect the prognosis?

Abstract

Background: Incidental gallbladder cancer is observed in up to 3.5% of patients undergoing laparoscopic cholecystectomy. To study the role of wall perforation on the prognosis, we evaluated a series of patients in whom perforation occurred during the cholecystectomy. Materials and Method: 109 patients who un-derwent a laparoscopic cholecystectomy in whom final diagnosis was gallbladder cancer were the focus of the study. We divided the patients according the occurrence of spillage. Furthermore, patients with spillage were divided into two categories according the spillage magnitude. Results: Of the patients, spillage was documented in 32 (29.3%). In 13 patients spillage was considered major. The median follow-up of patients was 36 months, while 35 (32.1%) patients died during the follow-up. Five-year survival of all patients with spillage was not statistically different from the group without spillage. However, the group with major spillage had a statistically worse survival than the rest. A Cox regression analysis including age, gender, level of invasion and spillage category showed that major spillage was independently associated with a worse prognosis.
