Oesophageal Stenting in Nairobi, Kenya

Oesophageal Stent Placement for Swallowing Difficulties, Obstruction and Selected Oesophageal Conditions

Oesophageal stenting is an endoscopic procedure used to open a narrowed or blocked section of the oesophagus and improve the passage of food and liquids. An oesophageal stent, usually a self-expanding metal stent (SEMS), is carefully positioned across the affected area to create and maintain an open channel.

At Endoscopy Center Nairobi, oesophageal stenting is performed using endoscopic techniques to assist patients with selected oesophageal obstructions, strictures, leaks and fistulas. Stent selection and placement depend on the underlying condition, location and length of the affected segment, and the patient's overall clinical situation.

When Is Oesophageal Stenting Recommended?

Oesophageal stenting may be considered in carefully selected patients with conditions that cause significant narrowing, obstruction or leakage.

Oesophageal Cancer

One of the most common applications of oesophageal stenting is palliation of dysphagia caused by advanced oesophageal cancer.

As an oesophageal tumour grows, it can narrow the passage through which food travels. This may cause:

• Difficulty swallowing solid food

• Difficulty swallowing soft foods

• Difficulty swallowing liquids

• Regurgitation

• Chest discomfort associated with swallowing

• Reduced food intake

• Weight loss

• Malnutrition

In appropriate patients, placement of an oesophageal stent can reopen the passage and improve the ability to swallow.

Benign Oesophageal Strictures

Some non-cancerous oesophageal strictures can become resistant to conventional endoscopic dilation. In selected cases, temporary stenting may be considered when other treatment approaches have not provided adequate results.

Benign strictures may occur following:

• Severe acid reflux

• Previous oesophageal injury

• Certain medical treatments

• Surgical procedures

• Inflammatory conditions

• Caustic injury

The decision to place a stent depends on the cause and characteristics of the stricture and should be made by the treating specialist.

Oesophageal Leaks

Selected oesophageal leaks may be treated with a covered stent. The stent can cover the area of leakage and help prevent oesophageal contents from passing through the defect.

Stenting may be considered in selected cases following:

• Oesophageal surgery

• Endoscopic procedures

• Oesophageal perforation

• Other causes of oesophageal leakage

Patients with suspected perforation or leakage require urgent specialist assessment.

Oesophageal Fistulas

An abnormal connection between the oesophagus and another structure, such as the respiratory tract, may sometimes be managed using a covered oesophageal stent.

The objective is to cover the fistula and reduce the passage of food or fluid through the abnormal opening.

Symptoms That May Require Assessment

Patients experiencing persistent swallowing difficulties should undergo medical evaluation to determine the underlying cause.

Symptoms that may warrant investigation include:

• Difficulty swallowing

• Painful swallowing

• Food getting stuck

• Progressive difficulty swallowing

• Regurgitation of food

• Persistent chest discomfort

• Unexplained weight loss

• Persistent vomiting

• Recurrent aspiration or coughing associated with swallowing

Difficulty swallowing that progressively worsens should not be ignored, particularly when accompanied by weight loss, bleeding or persistent vomiting.

How Is Oesophageal Stenting Performed?

Oesophageal stent placement is performed using an endoscope. The endoscope allows the medical team to examine the oesophagus and identify the area requiring treatment.

1. Patient Assessment

Before the procedure, the patient is assessed to determine whether oesophageal stenting is appropriate. The underlying condition, location of the obstruction, length of the narrowed segment and other relevant clinical factors are considered.

Imaging and previous endoscopy reports may also be reviewed.

2. Endoscopic Examination

A flexible endoscope is passed through the mouth and into the oesophagus. The endoscopist examines the affected area and identifies the obstruction, stricture, leak or fistula.

3. Stent Positioning

A guidewire and delivery system are used to position the stent accurately across the affected segment.

In many cases, fluoroscopic imaging may be used together with endoscopy to assist with accurate placement.

4. Stent Deployment

The stent is released from its delivery system. It gradually expands and presses against the oesophageal wall, creating an open passage.

The position of the stent is checked before completing the procedure.

5. Post-Procedure Monitoring

After the procedure, the patient is monitored by the medical team. The timing of restarting oral intake depends on the reason for stenting, the type and position of the stent, and the treating team's instructions.

Types of Oesophageal Stents

Different stent designs are available, and the appropriate device depends on the clinical indication.

Fully Covered Self-Expanding Metal Stents

Fully covered stents have a covering designed to limit tissue growing into the stent.

They may be considered when removability or sealing of a leak or fistula is important.

Partially Covered Self-Expanding Metal Stents

Partially covered stents have a covered central portion with uncovered sections that can help anchor the stent.

They may be used in selected malignant obstructions depending on the anatomy and treatment objectives.

Uncovered Self-Expanding Metal Stents

Uncovered stents allow tissue ingrowth through the mesh. They may provide strong anchoring but are generally not intended for routine removal.

The choice of stent should be individualized by the treating specialist.

What Are the Benefits of Oesophageal Stenting?

For appropriately selected patients, oesophageal stenting may:

• Improve swallowing

• Allow better passage of food and liquids

• Relieve symptoms caused by oesophageal obstruction

• Improve oral intake

• Help reduce complications associated with severe obstruction

• Seal selected oesophageal leaks

• Help manage selected oesophageal fistulas

• Improve quality of life in patients with advanced oesophageal cancer

The expected benefit depends on the underlying disease and the patient's overall condition.

Possible Risks and Complications

Although oesophageal stenting can be beneficial, it is not without risks.

Possible complications include:

• Chest or oesophageal discomfort

• Stent migration

• Food becoming trapped within the stent

• Tumour ingrowth or overgrowth

• Gastroesophageal reflux

• Bleeding

• Ulceration

• Perforation

• Aspiration

• Stent displacement

• Fistula-related complications

• Need for repeat endoscopy or additional treatment

The risks vary depending on the reason for stenting, the type of stent used, its location and the patient's medical condition.

What Happens After Oesophageal Stent Placement?

Patients receive specific instructions from the treating medical team after stent placement.

Dietary instructions are particularly important. Patients may initially be advised to follow a modified diet before gradually progressing according to their clinical response and medical advice.

Good eating practices after oesophageal stenting may include:

• Eating slowly

• Taking small bites

• Chewing food thoroughly

• Taking adequate fluids as advised

• Following the recommended diet

• Remaining upright after eating

• Following all medication instructions

Patients should contact their healthcare provider if they develop severe chest pain, difficulty swallowing, persistent vomiting, significant bleeding, fever or other concerning symptoms.
