Effective Treatment for Dacryocystitis: Dacryocystohinostomy with Stent Explained

Dacryocystitis, an infection of the lacrimal sac, can cause significant discomfort and complications if left untreated. When conservative treatments fail, surgical intervention becomes necessary. One of the most effective surgical options is dacryocystohinostomy with stent placement. This procedure restores proper tear drainage and prevents recurrent infections. This article explains the treatment in detail, helping patients and caregivers understand what to expect and why this approach works.

What Is Dacryocystitis?

Dacryocystitis occurs when the nasolacrimal duct, responsible for draining tears from the eye into the nose, becomes blocked or infected. This blockage leads to fluid buildup in the lacrimal sac, causing pain, swelling, redness, and sometimes pus discharge near the inner corner of the eye. If untreated, the infection can spread or cause abscess formation.

Common causes include:

• Chronic inflammation or infection

• Nasolacrimal duct obstruction due to injury or congenital issues

• Age-related narrowing of tear drainage pathways

  
  

Patients often experience tearing, discomfort, and swelling, which can interfere with daily activities and quality of life.

Why Surgery Is Needed

Initial treatment for dacryocystitis usually involves antibiotics and warm compresses to reduce infection and inflammation. However, if the underlying blockage remains, infections tend to recur. In such cases, surgery is the best option to restore tear drainage and prevent further episodes.

Dacryocystohinostomy (DCR) is the standard surgical procedure for this condition. It creates a new passage between the lacrimal sac and the nasal cavity, bypassing the blocked nasolacrimal duct. This allows tears to drain properly, reducing the risk of infection.

Understanding Dacryocystohinostomy with Stent

The addition of a stent during dacryocystohinostomy improves surgical outcomes. The stent is a small tube inserted into the newly created passage to keep it open during healing. This prevents scar tissue from closing the passage and ensures long-term success.

How the Procedure Works

• The surgeon makes a small incision near the inner corner of the eye or performs an endoscopic approach through the nasal cavity.

• The blocked nasolacrimal duct is bypassed by creating a new opening between the lacrimal sac and the nasal mucosa.

• A silicone stent is threaded through the tear drainage system, holding the new passage open.

• The incision is closed, and the stent remains in place for several weeks to months, depending on healing.

  
  

Benefits of Using a Stent

• Maintains patency of the new tear drainage route

• Reduces the chance of restenosis (reclosure)

• Improves tear flow and reduces symptoms faster

• Enhances overall surgical success rates, reported to be above 90% in many studies

  
  

What to Expect Before, During, and After Surgery

Before Surgery

Patients undergo a thorough eye and nasal examination. Imaging tests may be done to assess the extent of blockage. Doctors discuss the procedure, risks, and benefits, and provide preoperative instructions such as fasting or medication adjustments.

During Surgery

The procedure typically takes 45 minutes to an hour and is performed under local or general anesthesia. Patients usually go home the same day.

After Surgery

• Mild swelling and bruising around the eye are common.

• Antibiotic eye drops and nasal sprays help prevent infection.

• The stent remains in place for 6 to 12 weeks.

• Follow-up visits monitor healing and stent position.

• Patients should avoid rubbing the eye and strenuous activities during recovery.

  
  

Potential Risks and Complications

While dacryocystohinostomy with stent is generally safe, some risks include:

• Infection or bleeding

• Stent displacement or discomfort

• Scarring causing re-blockage

• Rare injury to surrounding structures

  
  

Choosing an experienced surgeon and following postoperative care instructions minimize these risks.

Real-Life Example

A 45-year-old woman with recurrent dacryocystitis underwent dacryocystohinostomy with stent placement after multiple antibiotic treatments failed. Within weeks, her symptoms resolved completely. The stent was removed after two months, and she remained symptom-free at one-year follow-up. This case highlights the procedure’s effectiveness in preventing recurrence and improving quality of life.

Summary

Dacryocystohinostomy with stent placement offers a reliable solution for patients suffering from dacryocystitis caused by nasolacrimal duct obstruction. By creating a new tear drainage pathway and keeping it open during healing, this surgery reduces infections and restores comfort. If you experience persistent tearing, swelling, or infections near the eye, consult an eye specialist to explore this treatment option. Early intervention can prevent complications and help you return to normal daily activities with clear, comfortable eyes.
