Role of Stent Insertion in Managing Obstructive Symptoms in Gastric Cancer

Patient Selection for Stent Placement vs. Surgical Bypass

The National Comprehensive Cancer Network recommends endoscopic placement of self-expanding metal stents (SEMS) as a safe, effective, and minimally invasive palliative treatment for patients with luminal obstruction due to advanced gastric cancer, particularly for those with shorter life expectancy 1, 2
For patients with shorter life expectancy, SEMS placement is preferred due to faster symptomatic relief, shorter hospital stays, and more rapid resumption of oral intake 1, 2
For patients with longer life expectancy, gastrojejunostomy may be preferable due to more durable long-term results and lower rate of reintervention 1, 2

Stent migration may require endoscopic repositioning or replacement 2
Severe uncontrolled pain after stent placement should be treated with immediate endoscopic removal of the stent 1, 3

Gastrojejunostomy is a surgical option for gastric outlet obstruction 1, 4
Gastrectomy may be considered in select patients 1, 4
External beam radiation therapy is a non-surgical alternative for symptom relief 1, 5
Balloon dilation is another non-surgical option for managing obstructive symptoms 6
Percutaneous decompressive gastrostomy can provide symptom relief 2

The National Comprehensive Cancer Network recommends external beam radiation therapy for pain control 1, 5
Appropriate pain medications should be used per NCCN Adult Cancer Pain guidelines 1, 2
NCCN Antiemesis guidelines should be followed for managing nausea and vomiting 1, 2
Nutritional counseling and appropriate feeding access are essential for nutritional support 1, 4, 5
