Wound recurrence from gallbladder cancer after open cholecystectomy.

Background: Reports of port site recurrences from gallbladder cancer after laparoscopic cholecystectomy have raised considerable concern as to whether the laparoscopic technique implies an increased risk of metastatic disease. In a previous study of gallbladder cancer and laparoscopic cholecystectomy, we reported a frequency of 16% port site metastases. The purpose of the present study was to determine the frequency of wound metastases from gallbladder cancer after open cholecystectomy.

Methods: The registers from the Swedish Oncological Centers and the National Board of Health and Welfare were checked for reported cases of gallbladder cancer and surgical classification codes for open cholecystectomy from 1991 to 1994. The study included all 8 university and 24 county hospitals in Sweden. The files from all patients with gallbladder cancer who had an open cholecystectomy were retrospectively reviewed.

Results: The study included 270 patients who had a cholecystectomy, of which 215 were classified as open and 55 as laparoscopic. Of the 215 patients, 11 patients were excluded because of an incorrect or deficient histopathologic or surgical classification. In 186 patients (91%), sufficient data were obtained for follow-up. Twelve patients (6.5%) had wound metastases from their gallbladder cancer. All patients with wound metastases died with a median survival of 10 months (range, 3 to 65 months).

Conclusions: Wound metastases from gallbladder cancer after open cholecystectomy may be more common than previously assumed.
