A Prospective Feasibility Study for TAMIS (TAMIS)

November 21, 2016 updated by: Mette Willaume Christoffersen, Hvidovre University Hospital

A Prospective Quality Assurance Feasibility Study of Laparoscopic Assisted Transanal Minimally Invasive Surgery (TAMIS) for Rectal Cancer

Most recently, the Transanal Minimally Invasive Surgery (TAMIS) approach combined with single-port technology has allowed that pelvic surgery can be laparoendocopically performed from both its abdominal and perineal aspects.Previously, a strong negative association between medium- and long-term survival and male gender with narrow pelvis have been reported. TAMIS has a significant potantial for improving the quality of the surgical resection of rectal tumors in men with visceral obesity and narrow pelvis. This group of patients have also a high rate of conversion to open surgery. Focusing on improvement in intraoperative conditions and surgical techniques rather than routine conventional procedures may be the way to go concerning favorable short- and long-term outcomes. The selection of adequate surgical approach to the high-risk patients with visceral obesity and a bulky mesentery may prevent or limit the risk for anastomotic leakage and improve oncologic margin clearence. This is a prospective observational feasability study of the TAMIS-procedure.

Description

Inclusion criteria:

  • rectal cancer with histological diagnosis
  • tumors located between 10 - 4 cm from the anal verge measured with a rigid rectoscope.
  • suitable for elective resection

exclusion criteria:

  • preoperative magnetic resonance imaging (MRI) showing diameter of tumor size >6 cm
  • American Society of Anesthesiologists (ASA) class IV and V
  • anticipated need of intensive care unit (ICU)
  • history of previous major abdominal surgery
  • computer assisted tomography (CT) or MRI evidence of tumor infiltration of adjacent organs
  • obese patient with body mass index >35kg/m2
  • those, who do not understand the requirements of the protocol
  • pregnancy
  • more than one colorectal tumor
