Summary
Self-expanding metallic stents treat gastric outlet obstruction, avoiding surgery. However, stent migration, like rectal displacement causing bowel obstruction, is a rare complication.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Surgical Oncology
Background:
- Gastric outlet obstruction (GOO) is a common complication of benign or malignant diseases.
- Self-expanding metallic stents (SEMS) are a minimally invasive treatment option for GOO.
- SEMS placement obviates the need for surgical bypass and allows patients to resume a normal diet.
Observation:
- Prosthesis displacement is a recognized late complication of SEMS.
- A rare case of SEMS migration to the rectum is presented.
- The patient exhibited symptoms and signs consistent with incomplete large bowel obstruction.
Findings:
- The migrated stent caused symptoms mimicking large bowel obstruction.
- This case highlights rectal migration as a potential, albeit infrequent, complication of SEMS for GOO.
Implications:
- Awareness of rare complications like stent migration is crucial for clinicians managing GOO.
- This case underscores the importance of long-term patient monitoring after SEMS placement.
- Further research may be needed to elucidate the mechanisms and prevention strategies for stent migration.
