Abstract

Transanal endoscopic microsurgery (TEM) is a minimally invasive technique for excision of rectal tumors that avoids conventional pelvic resectional surgery along with its risks and side effects. Although appealing, the associated cost and complex learning curve limit TEM use by colorectal surgeons. Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to TEM. This platform uses ordinary laparoscopic instruments to achieve high-quality local excision. The aim of the study is to assess reliability of the technique. From July 2012 to August 2013, 15 consecutive patients with rectal pathology underwent TAMIS. After a single-incision laparoscopic surgery port was introduced into the anal canal, a pneumorectum was established with a laparoscopic device followed by transanal excision with conventional laparoscopic instruments, including graspers, electrocautery, and needle drivers. Patient demographics, operative data, and pathologic data were recorded. Of the 15 patients, 10 had rectal cancers (six T1 lesions and four T2 after preoperative chemoradiotherapy). The remainder of patients had a local excision for voluminous benign rectal adenomas. The median length of the lesions from the anal verge was 7 cm (range, 4 to 20 cm). The median operating time was 86 minutes (range, 33 to 160 minutes). There was no surgical morbidity or mortality. The median postoperative hospital stay was two days (range, 1 to 4 days). TAMIS seems to be a feasible and safe treatment option for early rectal cancer. We believe that this new technique is easy to perform, cost-effective, and less traumatic to the anal sphincter compared with traditional TEM.
