A case of plural port site recurrences of incidental gallbladder carcinoma after laparoscopic cholecystectomy

Abstract

We report a case of plural port site recurrences of gallbladder carcinoma after laparoscopic cholecystectomy (LC). A 60-year-old man underwent a LC for cholecystolithiasis. After the operation, he was diagnosed as gallbladder carcinoma and received additional operative procedures. During the postoperative follow-up, an abdominal CT showed abdominal wall masses in the port-site of umbilicus and right midclavicular line. Aspiration biopsy cytology showed adenocarcinoma and was diagnosed as port site recurrences. Because of no other recurrences, an abdominal wall resection was performed after 14 months of the additional operation. We removed 3 masses including the abdominal wall from skin to peritoneum of the umbilicus and right midclavicular line port. Another mass was confirmed at the port-site on anterior axillary line during the operation and removed it surgically. Pathologically, the carcinoma was confined to the out-side of the parietal peritoneum in all abscission specimens and the recurrence pattern was extraperitoneal. In our case, it was thought to be a local recurrence without peritoneal dissemination, and radical operation was thought to have been performed.
