Abstract

Local excision is often fully justified for rectal carcinoid tumors. However insufficient surgical field and difficult access to proximal tumors have been drawbacks in performing pre-existing local excision procedures. A novel local excisional technique called minimally invasive transanal surgery (MITAS) has been experimented for local removal of carcinoid tumors in the rectum. A specially designed anal retractor connected to the Octopus retractor holder was used and an ENDO-stapler allowed the simultaneous excision and anastomosis to be performed. Eight patients with carcinoid tumors in the rectum (4 tumors in the upper rectum) underwent MITAS. Median distance from anal verge to proximal tumor was 6.5 cm (range, 5-12 cm). The median diameter of the tumor was 9 mm. Median operative time was 18.5 minutes and blood loss was minimal. No analgesics were needed postoperatively, and there was no morbidity or mortality. Full-thickness excision of the rectum was accomplished and the tumors confined in the submucosa were demonstrated histologically to be with free surgical margins. No recurrences have been observed with a median follow-up period of 39 months. The technique facilitates total excisional biopsy for rectal carcinoid tumors and reduces operative time, blood loss and complications.
