Palliative stenting of malignant large bowel obstruction
Summary
Palliative colonic stenting effectively relieved malignant large bowel obstruction in 18 of 20 patients. This endoscopic procedure offers an alternative to stomas, potentially reducing patient and carer burden.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Oncology
Background:
- Malignant large bowel obstruction is a life-threatening condition.
- Palliative stoma formation can be burdensome for patients with advanced cancer.
- Endoluminal stenting presents a potential alternative for symptom palliation.
Purpose of the Study:
- To evaluate the efficacy and safety of palliative endoluminal colonic stenting.
- To assess the impact of stenting on symptom relief and patient burden.
Main Methods:
- Retrospective review of 20 patients with left-sided colonic cancers.
- Endoscopic placement of colonic stents using a 'stent over wire' technique.
- Radiological guidance during stent deployment.
Main Results:
- Successful relief of obstruction in 18 out of 20 patients.
- Median palliation duration of 50 days for deceased patients and 80 days for surviving patients.
- One stent-related complication (anal pain due to migration) occurred after 250 days.
Conclusions:
- Palliative colonic endoluminal stenting is a beneficial option for carefully selected patients.
- Stenting effectively relieves obstructive symptoms and may avoid the complications of palliative stomas.
