44370 Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with transendoscopic stent placement (includes predilation)

Name of the Procedure:

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with transendoscopic stent placement (includes predilation).
Common name(s): Enteroscopy with stent placement

Summary

Enteroscopy with stent placement is a medical procedure where a flexible tube with a camera (endoscope) is inserted into the small intestine beyond the second portion of the duodenum. The procedure involves placing a stent (a small tube) to keep a narrowed or blocked section of the intestine open. Predilation, or the widening of the intestine, is included before the stent is placed.

Purpose

Medical Condition or Problem:

This procedure addresses obstructions or severe narrowings (strictures) in the small intestine that can cause symptoms like pain, vomiting, and difficulty digesting food.

Goals or Expected Outcomes:

The goal is to alleviate obstruction, improve food passage, relieve symptoms, and enhance the patient's quality of life.

Indications

Specific Symptoms or Conditions:

• Chronic abdominal pain
• Vomiting
• Unexplained nausea
• Severe weight loss
• Malnutrition due to intestinal blockage

Patient Criteria:

Patients with confirmed small intestinal obstructions or strictures that cannot be managed with medication alone.

Preparation

Pre-procedure Instructions:

• Fasting (usually for 8-12 hours before the procedure)
• Adjustments to current medications as directed by the physician
• Complete any prescribed bowel preparation solutions

Diagnostic Tests:

• Blood tests
• Imaging studies like a CT scan or MRI
• Review of medical history and physical examination

Procedure Description

1. Anesthesia: The patient is usually given conscious sedation or general anesthesia.
2. Insertion: The endoscope is carefully inserted through the mouth and advanced beyond the second portion of the duodenum.
3. Navigation: The endoscope’s camera allows the doctor to navigate through the intestines.
4. Assessment: The narrowed area is located and assessed.
5. Predilation: The area is dilated (widened) using a special balloon.
6. Stent Placement: A stent is placed in the dilated area to keep it open.
7. Confirmation: Placement is confirmed with imaging, and the endoscope is carefully withdrawn.

Tools, Equipment, Technology:

• Flexible endoscope with a camera
• Balloon dilator
• Stent deployment system

Duration

The procedure typically takes between 1 to 3 hours, depending on the case complexity.

Setting

Enteroscopy with stent placement is performed in a hospital or an outpatient surgical center equipped with endoscopic facilities.

Personnel

• Gastroenterologist or surgeon performing the procedure
• Nurses or endoscopy technicians assisting
• Anesthesiologist (if general anesthesia is used)

Risks and Complications

Common Risks:

• Sore throat
• Mild abdominal discomfort

Rare Risks:

• Perforation (tear) of the intestine
• Infection
• Bleeding
• Stent migration or occlusion

Management of Complications:

Complications are managed with medications, additional procedures, or surgery, if necessary.

Benefits

• Relieves symptoms of obstruction
• Improves nutritional absorption
• Reduces pain and discomfort
• Enhances overall quality of life ##### Realization of Benefits: Benefits are often realized immediately after the procedure with gradual improvement over days to weeks.

Recovery

Post-procedure Care:

• Observational period in a recovery area
• Pain management as needed
• Gradual reintroduction of diet

Recovery Time:

Full recovery typically takes a few days, with most patients resuming normal activities within a week.

Restrictions and Follow-up:

• Avoid strenuous activities for a few days
• Follow-up appointments to monitor stent position and efficacy

Alternatives

Other Treatment Options:

• Medication to manage symptoms
• Surgical intervention to bypass or remove the obstruction

Pros and Cons:

• Medications: Less invasive but often less effective for severe obstructions.
• Surgery: More definitive but involves longer recovery and higher risk.

Patient Experience

During Procedure:

The patient may experience a sensation of pressure or discomfort initially, generally well-managed with sedation.

After Procedure:

Soreness in the throat or mild abdominal discomfort may occur. Pain is typically mild and managed with over-the-counter analgesics.

Pain Management:

Mild pain relief medications and supportive care ensure patient comfort during recovery.
