A Case of Laparoscopic Resection for Solitary Peritoneal Recurrence of Rectal Cancer

Abstract

A 74-year-old man with rectal cancer underwent laparoscopic low anterior resection in December 2013. After surgery, he was administered adjuvant chemotherapy for 4 months, but the treatment had to be discontinued because of the emergence of adverse events. The serum carcinoembryonic antigen level was elevated to 5.6 ng/ml in August 2015. However, abdominal computed tomography (CT) revealed no metastasis or recurrence for 1 year. In November 2016, CT and fluorodeoxyglucose positron emission tomography (FDG-PET) showed local recurrence in the peritoneum. He was referred for a laparoscopic tumor resection of the local recurrence. Histological examination of the recurrent tumor revealed moderately differentiated adenocarcinoma. Until now, 11 months since, the patient has been in remission. Laparoscopic tumor resection of the local recurrence showed therapeutic benefit in this patient.
