Coincident Port-site and Functional End-to-end Anastomotic Recurrences after Laparoscopic Surgery for Colon Cancer: A case report and literature review

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 inMarch 2016. The tumours at the functional end-to-end anastomosisand functional end-to-end anastomosiswere resected. After 7 months, no recurrence was detected.
