Abstract

Port site recurrence after laparoscopic surgery for colorectal cancer patients is a rare complication. We report a case of port site recurrence in a 46-year-old woman that was detected by positron emission tomography (PET) using 18[F]-fluoro-deoxyglucose (FDG). Surgical treatment consisted of laparoscopic ileo-cecal resection and lymph node dissection. At her nine months postoperative follow-up examination, her serum carcinoembryonic antigen (CEA) levels had raised to 15.8ng/mL. Although computed tomography and colonoscopic examination were performed, lung, liver and local recurrence in the colon were not detected. FDG-PET was then performed and detected a higher concentration of FDG at the port site in the abdominal wall. Port site recurrence was diagnosed clinically and surgical resection of tumor at the port site was performed. Pathology revealed a moderately differentiated adenocarcinoma diagnosed as port site recurrence. This case suggests that FDG-PET is an important examination for the detection of port site recurrence when serum CEA levels are rising and routinely radiographic examinations are unable to detect the site of recurrence.
