Endoscopic laser treatment offers symptom relief for advanced rectosigmoid cancer patients. For benign villous adenomas, it

Area of Science:

  • Gastroenterology
  • Oncology
  • Surgical Technology

Background:

  • Rectosigmoid tumors present a significant clinical challenge.
  • Both advanced cancers and benign villous adenomas require effective treatment strategies.

Purpose of the Study:

  • To evaluate the efficacy and safety of endoscopic laser treatment for rectosigmoid tumors.
  • To assess outcomes for patients with advanced cancer versus benign villous adenoma.

Main Methods:

  • Retrospective analysis of 746 patients treated over 14 years at the Lille Laser Center.
  • Categorization of patients into advanced cancer (n=272) and villous adenoma (n=474) groups.
  • Assessment of immediate success, complication, and recurrence rates, with long-term follow-up.

Main Results:

  • High immediate success rates (85% for cancer, 92.8% for adenoma) with low complication rates (2% and 1.8%).
  • Advanced cancer patients experienced sustained functional improvement for an average of 10.1 months.
  • Villous adenoma recurrence rate was 18% over a 29.7-month follow-up.

Conclusions:

  • Endoscopic laser therapy provides palliative relief for inoperable advanced rectosigmoid carcinomas.
  • Careful patient selection is crucial for endoscopic laser treatment of villous adenomas, particularly for non-surgical candidates.
  • The risks of surgery must be weighed against the benefits of endoscopic laser treatment on a case-by-case basis.
