Transanal endoscopic microsurgery (TEM) effectively removes rectal tumors with no recurrences or incontinence. This minimally invasive technique is suitable for benign rectal tumors and selected early rectal cancers.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Colorectal Surgery

Context:

  • Transanal endoscopic microsurgery (TEM) introduced in 1984 for rectal tumor removal.
  • TEM allows for transanal tumor excision up to 20 cm above the anal verge.

Purpose:

  • Evaluate the efficacy and safety of TEM for rectal adenomas and early rectal cancer.
  • Assess oncological outcomes, complication rates, and functional results following TEM.

Summary:

  • 18 transmural and 2 mucosal resections performed for 16 rectal adenomas and 4 early rectal cancers.
  • Median operation time: 85 minutes; median hospital stay: 3 days.
  • All tumors resected radically with clear margins; no serious complications or recurrences observed at median 10-month follow-up.

Impact:

  • TEM demonstrates excellent functional outcomes with no patient incontinence.
  • TEM is a viable option for benign rectal tumors and selected early rectal cancers.
  • Highlights the minimally invasive approach's effectiveness in rectal surgery.
