Videoendoscopic transanal tumor resection (VTEM) offers a cost-effective, minimally invasive alternative for rectal tumors. This modified technique using standard laparoscopic equipment is teachable and yields good patient outcomes with low complication rates.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Transanal resection is a standard technique for rectal tumors.
  • Transanal endoscopic microsurgery (TEM) offers precision but is limited by cost and complexity.
  • A modified TEM approach using standard laparoscopic equipment was developed.

Purpose of the Study:

  • To present the technique and outcomes of videoendoscopic transanal tumor resection (VTEM).
  • To evaluate the feasibility of training surgeons in VTEM.
  • To assess the cost-effectiveness and patient benefits of VTEM.

Main Methods:

  • Four surgeons were trained in VTEM.
  • A prospective database of VTEM cases was maintained.
  • Indications, operative times, complications, and outcomes were reviewed.

Main Results:

  • 27 VTEM cases were performed between August 1994 and June 1996.
  • Average operating time was 127 minutes, longer for proximal lesions and early cases.
  • Post-operative complications occurred in 15% of patients, with low recurrence rates.

Conclusions:

  • VTEM is a teachable technique for colorectal surgeons.
  • Utilizing standard laparoscopic equipment reduces initial setup costs.
  • VTEM provides an effective, minimally invasive surgical option with good outcomes and short hospital stays.
