Overview
Surgery is the most definitive therapy for the Zenker's diverticulum (ZD). If small and asymptomatic, no treatment is necessary. Larger, symptomatic cases of Zenker's diverticulum have been traditionally treated by neck surgery to resect the diverticulum and incise the cricopharyngeus muscle. However, in recent times non-surgical endoscopic techniques have gained more importance, and the currently preferred treatment is the endoscopic stapling i.e. closing of the diverticulum via a stapler inserted through a tube in the mouth. This may be performed through a fiberoptic endoscope. Other non-surgical treatment modalities exist, such as endoscopic laser, which recent evidence suggests it less effective than stapling.
Surgery
- If small and asymptomatic, no treatment is necessary.
- Larger, symptomatic cases of Zenker's diverticulum have been traditionally treated by neck surgery to resect the diverticulum and incise the cricopharyngeus muscle.
- However, in recent times non-surgical endoscopic techniques have gained more importance as they allow for much faster recovery, and the currently preferred treatment is endoscopic stapling[1][2] (i.e. closing of the diverticulum via a stapler inserted through a tube in the mouth).
- This may be performed through a fibreoptic endoscope[3].
- Other non-surgical treatment modalities are endoscopic laser, recent evidence suggesting that it is less effective than stapling.[4]
- Various surgeries performed for the ZD are as follows:
- Rigid endoscopic diverticulotomy
- Flexible endoscopic diverticulotomy
Rigid Endoscopic Diverticulotomy
-Four types of procedures are performed using rigid scope
1.Endoscopic electrocautery[5][6]
- This is suitable for smaller lesions and is performed via an endoscope.
- A double-lipped esophagoscope is used and the wall between the diverticulum and esophageal wall is exposed.
- The hypopharyngeal bar is divided with diathermy or laser.
- Shorter duration of anaesthesia.
- More rapid resumption of oral intake.
- Shorter hospital stay.
- Quicker recovery.
Complications
- Sub-cutaneous emphysema
- Mediastinitis
- Aspiration from the pouch
2.Endoscopic CO2 Laser Technique[7][8]
- This technique offers high energy and high focused beam.
- Very minimal tissue trauma.
- It also provides a better visualization of the diverticular bridge and easier control of the operation.
Complications
3.Endoscopic Stapling[9]
- This cuts and seal the edge of the wound simultaneously,
- Low incidence of perforation and bleeding.
- Thermal damage to the recurrent laryngeal nerve can be prevented with this procedure.
4.Endoscopic Harmonic Scalpel
Flexible Endoscopic Diverticulotomy
- The procedure is done with an extended neck under sedation, general anesthesia is not required.
- The septum between the diverticulum and esophageal lumen can be visualized by the hood, endoscopic cap, and overtube and stabilized without overextension of the neck.
- The knifes used for the incision are as follows
- Needle-knife
- Hook-knife
- Argon plasma coagulation
- Monopolar forceps
Complications of the Endoscopic procedures[10]
- Emphysema (Mediastinal/Cervical)
- Esophageal perforation
- Dental Injury
- Bleeding
- Mediastinitis
- Leak
- Recurrent laryngeal nerve injury
- Infection
