Transanal local excision of carcinoid tumors in the upper rectum under proctoscope: A clinical report of 6 cases / 中国微创外科杂志

ABSTRACT

Objective To study surgical techniques and clinical effects of minimally invasive excision of high rectal carcinoid tumors with anus preservation. Methods We conducted transanal local excision of rectal carcinoid tumors in 6 cases by using self-made proctoscope and laparoscopic instruments from August 2002 to January 2005. The tumors were located on the depth of 9~12 cm from the anal verge, and excision margin was 0.5~1 cm from the tumors. Results All the operations were performed successfully. A follow-up for 3~28 months (mean, 15 months) found no recurrence, metastasis, rectal stenosis, or other short- or long-term complications. The postoperative hospital stay was 3~6 days. No analgesics were required. Conclusions Transanal local excision of high rectal carcinoid tumors under proctoscope is safe, reliable, minimally invasive, and cost-effective.
