Transanal endoscopic microsurgery by transanal glove port combined with colonoscopy for excision of rectal tumors / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the feasibility and efficacy of transanal endoscopic microsurgery (TEM) by transanal glove port combined with colonoscopy for excision of rectal tumors.</p><p><b>METHODS</b>Eight patients with rectal cancer eligible for local resection were chosen to receive a procedure performed via a "glove TEM port" from October 2012 to March 2013. This device was constructed on-table using a circular anal dilator (CAD), standard surgical glove, colonoscopy instruments and straight laparoscopic instruments.</p><p><b>RESULTS</b>Procedures of all the patients were completed successfully by glove TEM. The median (range) diameter of tumor was 2.6(1.5-3.5) cm, the median (range) operative time was 55.6(30-110) min. Postoperative pathology included villous adenomas (n=3), tubular adenomas (n=2), tubulovillous adenomas (n=2), serrated adenoma (n=1), low-grade intraepithelial neoplasia (n=2), and high-grade intraepithelial neoplasia (n=1). All resection margins were negative. Two patients presented with postoperative minor bleeding. There were no serious intraoperative complications. No cancer recurrence was found during a follow-up of 1-5 (median 3.1) months.</p><p><b>CONCLUSION</b>Transanal endoscopic microsurgery by transanal glove port combined with colonoscopy in the treatment of early rectal cancer is easy and safe.</p>
