[Trans-anal resection for recurrence of a very low rectal anastomosis at the suture line after colorectal cancer surgery].
When a relatively small anastomotic recurrence of colorectal cancer is detected in the low rectum, trans-anal resection (TAR) might be an option both for curative intent and for preservation of anal function. We report 3 such cases. Case No. 1: A 58-year-old woman presented with an anastomotic recurrence of sigmoid colon cancer. Low anterior resection(LAR)was performed. Two small recurrent nodules were detected at the suture line 1 year after LAR, which were successfully treated with TAR. The depth of the nodules indicated T2 cancer. The patient remained cancer free 5 years after TAR. Case No. 2: A 56-year-old man developed a severe anastomotic stenosis and an anastomotic recurrence 6 months after LAR for low rectal cancer. TAR was performed circumferentially to resect both the stricture and the recurrence. The depth of the nodule indicated T2 cancer. The patient was cancer free for 7 years after TAR. Case No. 3: A 54-year-old man developed 2 small recurrent nodules at the suture line after LAR for low rectal cancer. TAR was performed. The depth of the nodule indicated T1 cancer. One of the nodules was not resected, which necessitated intersphincteric resection (ISR) 10 months later. In conclusion, in cases of a relatively small recurrence of low rectal anastomosis after colorectal cancer surgery, TAR is an effective treatment option.
