Canine Dacryocystorhinostomy (DCR) Surgery: Pre- and Post-Operative Care Guidelines48

Canine dacryocystorhinostomy (DCR) surgery is a specialized procedure performed to correct obstructions in the nasolacrimal system, which is responsible for draining tears from the eyes. This surgery involves creating a new drainage pathway between the lacrimal sac and the nasal cavity, allowing tears to bypass the blocked tear duct and drain properly.

Pre-Operative Care

Pre-Anesthetic Evaluation: Before surgery, your veterinarian will perform a thorough physical examination and blood work to ensure your dog is healthy enough to undergo anesthesia. They will also discuss any potential risks or complications associated with the procedure.

Antibiotic Therapy: To prevent infection, your veterinarian may prescribe antibiotics prior to surgery. These antibiotics will typically be started several days before the procedure and continued for a period of time afterward.

Fasting: Dogs should be fasted for 8-12 hours prior to surgery to minimize the risk of regurgitation during anesthesia.

Surgical Procedure

DCR surgery is typically performed under general anesthesia. The procedure involves making an incision near the inner corner of the eye, exposing the lacrimal sac. A small opening is then created in the sac and connected to the nasal cavity, creating a new drainage pathway for tears.

The surgery usually takes approximately 45-60 minutes to complete. In some cases, a stent or tube may be placed in the new drainage channel to keep it open during the healing process.

Post-Operative Care

Pain Management: Your veterinarian will provide pain medication to keep your dog comfortable after surgery. It is important to administer these medications as directed.

Rest and Activity Restriction: Dogs should be kept calm and quiet for the first 24-48 hours after surgery. Avoid strenuous activity or excessive head movement, as this can put pressure on the incision.

Elizabethan Collar: An Elizabethan collar (cone) will be placed around your dog's neck to prevent them from scratching or rubbing their eyes, which can interfere with the healing process.

Eye Drops and Ointments: Your veterinarian will prescribe eye drops or ointments to be applied to the affected eye several times a day. These medications help reduce inflammation, prevent infection, and promote healing.

Sutures: The surgical incision will typically be closed with dissolvable sutures that will break down and fall out on their own within 10-14 days. If non-dissolving sutures are used, they will need to be removed by your veterinarian at a later date.

Follow-Up Appointments: Regular follow-up appointments will be scheduled with your veterinarian to monitor the healing process and ensure the new drainage pathway is functioning properly. During these appointments, your veterinarian may flush the lacrimal sac to remove any debris or check for any signs of infection.

Possible Complications

As with any surgical procedure, there are potential risks and complications associated with DCR surgery. These complications can include:
Bleeding
Infection
Scarring
Failure of the new drainage pathway to function properly
Delayed wound healing

Conclusion

Canine DCR surgery is a safe and effective procedure for treating obstructions in the nasolacrimal system. By carefully following the pre- and post-operative care instructions provided by your veterinarian, you can help ensure a successful outcome and a comfortable recovery for your dog.
