Transanal endoscopic microsurgery (TEMS) offers a minimally invasive approach for rectal polyps and early cancers. This technique demonstrated low morbidity and no local recurrence in a recent study.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Gastroenterology

Background:

  • Transanal endoscopic microsurgery (TEMS) is an advanced technique for rectal procedures.
  • It combines endoscopic visualization with surgical instrumentation under gas insufflation.

Purpose of the Study:

  • To report the experience and outcomes of transanal endoscopic microsurgery.
  • To evaluate TEMS for the treatment of rectal polyps and early rectal cancers.

Main Methods:

  • Prospective clinical trial involving 35 consecutive patients.
  • Indications included broad-based sessile polyps and early rectal cancers (pT2, G1-2).
  • Procedures involved total wall excisions or mucosectomy.

Main Results:

  • Histologic examination revealed 9 adenomas and 21 adenocarcinomas.
  • Morbidity was 5.6% for perioperative and 5.6% for late complications.
  • No operative mortality, mean hospital stay of 6 days, and no local recurrence observed during a mean follow-up of 10.3 months.

Conclusions:

  • Transanal endoscopic microsurgery is a preferred procedure for rectal polyps and early cancers.
  • Strict patient selection is crucial for successful outcomes.
  • The technique shows promising results with low recurrence rates.
