Abstract

Herein, we report coincident recurrences at the port site and functional end-to-end anastomosis after laparoscopic right hemicolectomy for cancer of the ascending colon. The patient was an 83-year-old man who had undergone the aforementioned procedure (Stage IIA) in the referral hospital. At the 10-month follow-up, computed tomography showed two tumours around 3 cm in diameter: one on the right-flank abdominal wall - the surgical port-site - and the other at the functional end-to-end anastomosis. Likewise, a positron emission tomography scan was positive for two tumours. Endoscopic examination showed an ulcerated tumour with a clear margin, and a biopsy confirmed moderately differentiated tubular adenocarcinoma. The patient was diagnosed with coincident recurrences at the port site and functional end-to-end anastomosis after laparoscopic right hemicolectomy for cancer of the ascending colon. We re-operated in March 2016. The tumours at the functional end-to-end anastomosisand functional end-to-end anastomosiswere resected. After 7 months, no recurrence was detected. J. Med. Invest. 64: 177-180, February, 2017
