BACKGROUND: Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to transanal endoscopic microsurgery. We assessed the feasibility of TAMIS for lesions located in the mid rectum.
METHODS: From July 2010 to October 2011, 16 consecutive patients with rectal pathology underwent TAMIS. After a single-incision laparoscopic surgery port was introduced into the anal canal, pneumorectum was established with a laparoscopic device, followed by transanal excision with conventional laparoscopic instruments, including graspers, monopolar electrocautery, and needle drivers. Clinicopathological findings, surgical procedure results, and perioperative outcomes were determined prospectively.
RESULTS: Of the 16 patients, 11 had rectal cancers (3 T1 lesions and 8 after preoperative chemoradiotherapy), 4 had neuroendocrine tumors, and 1 had a mucocele. The median length of the lesions from anal verge was 7.5 cm (range 4-10 cm). All procedures were completed laparoscopically without conversion to conventional transanal approach. The median operating time was 86 min (range 33-160 min), and the median estimated blood loss was 15 ml (range 0-150 ml) with no patient requiring intraoperative transfusions. There was no surgical morbidity or mortality, but one patient died during follow-up due to synchronous advanced gastric cancer. The median postoperative hospital stay was 3 days (range 2-6 days).
CONCLUSIONS: TAMIS seems to be a feasible and safe treatment option for lesions located in the mid rectum.
