Summary
Expandable metallic stents can palliate malignant gastrointestinal obstructions. This study reports on their use in the stomach, jejunum, and colon, with manageable complications and a median survival of 9 months.
Area of Science:
- Gastroenterology
- Interventional Endoscopy
- Oncology
Background:
- Expandable metallic prostheses are established for malignant biliary strictures.
- Their application is expanding to malignant dysphagia and esophago-airway fistulas.
- Potential exists for their use in gastrointestinal neoplasms beyond the esophagus.
Purpose of the Study:
- To report the experience with expandable metallic stents in the stomach, jejunum, and colon.
- To evaluate the efficacy and safety of these prostheses for malignant gastrointestinal stenoses.
Main Methods:
- Retrospective review of patients receiving expandable gastrointestinal stents (excluding biliary/esophageal).
- Data collected included indications, stent type/location, demographics, procedural issues, and outcomes.
- Nine patients with widespread malignancy received stents over a 6-year period.
Main Results:
- Stents were placed for afferent loop, colon, gastric outlet, and esophagojejunal interposition strictures.
- Complications included one colon perforation, one stent migration, one food bolus occlusion, and three tumor overgrowths treated with laser.
- Median patient survival was approximately 9 months.
Conclusions:
- Expandable metallic prostheses offer a palliative option for malignant gastrointestinal stenoses.
- These stents can be an alternative to surgical bypass or comfort care in select cases.
