Summary

Transanal endoscopic microsurgery (TEM) offers a low complication rate for rectal conditions. Careful patient selection for TEM surgery leads to superior outcomes in treating small, superficial rectal cancers and adenomas.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Surgical Oncology

Background:

  • Transanal endoscopic microsurgery (TEM) instrumentation became regularly available in the US in 1990.
  • This study compiles data from the earliest US registry of TEM procedures (1990-1994).

Purpose of the Study:

  • To report outcomes of the initial cohort of Transanal endoscopic microsurgery (TEM) procedures in the United States.
  • To evaluate complication rates, recurrence, and treatment success for various rectal pathologies treated with TEM.

Main Methods:

  • A voluntary registry collected data on 153 cases from six surgeons between 1990 and 1994.
  • Pathologies included 54 carcinomas, 82 adenomas, and 17 other rectal entities.
  • Data on technical difficulties, complications, hospital stay, and blood loss were recorded.

Main Results:

  • Carcinoma recurrence rates were 10% (T1), 40% (T2), and 66% (T3).
  • Adenoma recurrence was 11%, with easily treatable recurrences.
  • Overall complication rates were low: 9% technical difficulties, 15% early, and 5% late complications.

Conclusions:

  • Transanal endoscopic microsurgery (TEM) demonstrates a low complication profile.
  • Careful selection of patients with small, superficial rectal cancers and adenomas is key to achieving superior outcomes with TEM compared to other rectal surgery approaches.
