Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Interventional Radiology

Background:

  • Malignant large bowel obstruction presents a significant clinical challenge.
  • Effective management strategies are crucial for patient outcomes.

Purpose of the Study:

  • To review and report institutional experience with colorectal stenting.
  • To evaluate the efficacy and safety of self-expanding metallic stents in malignant large bowel obstruction.

Main Methods:

  • Retrospective review of 12 consecutive patients with malignant left-sided large bowel obstruction.
  • Insertion of self-expanding metallic stents under fluoroscopic or combined fluoroscopic/endoscopic guidance.
  • Follow-up until death, stent removal, or publication.

Main Results:

  • 13 stents were successfully inserted in 12 patients, achieving 92.9% technical success and 100% clinical success.
  • Obstruction relief was achieved in 11 patients; one required a second stent.
  • Stenting served as definitive treatment in 9 patients and as a bridge to surgery in 3 patients.
  • Complications included stent migration, reobstruction, and gastrointestinal bleeding.

Conclusions:

  • Colorectal stenting is a valuable treatment for malignant large bowel obstruction.
  • It can be used as a definitive therapy or as a bridge to elective surgical resection.
  • Self-expanding metallic stents offer a minimally invasive option for palliation and treatment.
