Clinical Scorecard: Assisted Placement of Enteral Stents in Malignant Colorectal Obstruction: A Case Study
At a Glance
| Category | Detail |
|---|
| Condition | Malignant bowel obstruction secondary to colorectal cancer |
| Key Mechanisms | Endoscopic placement of self-expandable metallic stents (SEMS) for obstruction relief |
| Target Population | Patients with malignant colorectal obstruction |
| Care Setting | Endoscopy |
Key Highlights
- Successful use of the EyeMax system for guidewire placement in complex strictures
- Immediate symptom relief following stent placement
- Patient underwent radical resection one month post-stent placement without complications
- One-year follow-up showed no recurrence of obstruction or tumor
Guideline-Based Recommendations
Diagnosis
- Diagnosis of malignant bowel obstruction confirmed via imaging and colonoscopy
Management
- Endoscopic placement of SEMS as a palliative treatment or bridge to surgery
Monitoring & Follow-up
- Post-procedure monitoring for symptom relief and complications
Risks
- Potential complications include perforation, bleeding, and fecalith obstruction
Patient & Prescribing Data
39-year-old woman with sigmoid colon adenocarcinoma
Chemotherapy prior to stent placement; successful stent deployment under direct visualization
Clinical Best Practices
- Utilize direct visualization systems for guidewire placement in strictures
- Monitor for complications post-stent placement
- Consider stent placement as a bridge to surgery in selected patients
