Port site recurrence of unexpected gallbladder carcinoma after a laparoscopic cholecystectomy: report of a case.

Unexpected gallbladder carcinoma was identified in a 71-year-old woman after she underwent a laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis. A subsequent laparotomy for a resection of the liver bed and a dissection of the lymph nodes around the hepatoduodenal ligament was done. Two and a half years later, the patient developed subcutaneous metastasis at the epigastric trocar site through which the gallbladder was removed. A third operation was thus performed, revealing no evidence of peritoneal dissemination, liver metastasis, or lymph node metastasis, and the abdominal wall mass was resected. The histological findings confirmed the diagnosis of metastatic carcinoma of the gallbladder. We recommend that when planning LC, the possibility of malignancy should thus be kept in mind. However, if there is any sign which does not completely exclude malignancy, such as a contracture or wall thickness of the gallbladder, LC should be performed by the abdominal wall lifting method and using a protective bag for the removal of the gallbladder.
