What are the indications for ERCP intestinal stent insertion?

ERCP (Endoscopic Retrograde Cholangiopancreatography) with intestinal stent insertion is typically indicated for conditions that cause obstructions or narrowing in the biliary, pancreatic, or intestinal systems. The stent is inserted to restore normal flow, decompress obstructions, and improve patient comfort, especially in cases where surgery is not feasible.

Here are the primary indications for ERCP intestinal stent insertion:

1. Malignant Biliary Obstruction

• Condition: Tumors or cancers (e.g., pancreatic cancer, cholangiocarcinoma, or liver cancer) obstructing the bile ducts.

• Purpose: To relieve biliary obstruction and jaundice caused by tumors blocking the bile ducts, allowing bile to flow from the liver to the intestine.

• Stent Type: Self-expanding metal stents (SEMS) or plastic stents.

• Benefit: Provides palliative care for advanced cancer, improving quality of life by relieving jaundice and other related symptoms.

2. Pancreatic Duct Obstruction

• Condition: Obstruction of the pancreatic duct, usually caused by tumors, pancreatitis, or strictures.

• Purpose: To drain pancreatic fluid, relieve pancreatic duct pressure, and prevent or treat pancreatitis.

• Stent Type: Plastic or metal stents.

• Benefit: Helps prevent infection, reduce pain, and manage complications like pancreatitis.

3. Malignant Duodenal Obstruction

• Condition: Tumors (e.g., pancreatic or gastric cancers) causing duodenal obstruction.

• Purpose: To relieve gastric outlet obstruction (blocked passage between the stomach and small intestine), allowing food to pass through.

• Stent Type: Covered metal stents (SEMS).

• Benefit: Improves gastric emptying, nutritional intake, and overall comfort in patients with advanced cancer.

4. Bile Duct or Pancreatic Duct Stricture

• Condition: Strictures (narrowing) due to inflammation, surgery, infection, or chronic pancreatitis.

• Purpose: To open up narrow ducts, allowing proper drainage of bile or pancreatic secretions.

• Stent Type: Plastic stents or metal stents.

• Benefit: Prevents infections, reduces the risk of duct rupture, and alleviates pain or digestive issues caused by the narrowing.

5. Post-Surgical Biliary Leaks

• Condition: Bile leakage after biliary surgery (e.g., after gallbladder removal or bile duct surgery).

• Purpose: To drain bile and prevent bile from leaking into surrounding tissues.

• Stent Type: Plastic stents.

• Benefit: Promotes healing and prevents further complications related to bile leakage.

6. Malignant or Benign Strictures (Other than Biliary)

• Condition: Strictures or obstructions in areas like the duodenum, jejunum, or ileum caused by tumors, scarring, or inflammatory bowel diseases.

• Purpose: To relieve the obstruction, allow food to pass, and prevent bowel perforation or malnutrition.

• Stent Type: Covered or uncovered SEMS, depending on the location and type of obstruction.

• Benefit: Provides temporary relief in cases where surgical intervention is not an option, especially in cases of malignant obstructions.

7. Colorectal Obstruction (In Some Cases)

• Condition: Colorectal cancer causing obstruction in the colon.

• Purpose: To relieve the obstruction and allow for better bowel function, especially if surgery is not an option.

• Stent Type: Self-expanding metal stents (SEMS).

• Benefit: Non-surgical management of malignant colonic obstruction, potentially delaying the need for surgery.

8. Duodenal Stent Insertion for Palliative Care in Cancer Patients

• Condition: Gastric outlet obstruction caused by pancreatic, gastric, or duodenal cancers.

• Purpose: To allow food to pass from the stomach into the small intestine, relieving symptoms like vomiting and nausea.

• Stent Type: Covered metal stents (SEMS).

• Benefit: Improves quality of life by reducing vomiting and improving nutritional intake.
