Zenker`s Diverticulum and CP Dysfunction
Zenker’s Diverticulum and CP Dysfunction Fact and Fiction Joshua S. Schindler, MD Assistant Professor Department of Otolaryngology ASHA 2011 San Diego November 18, 2010 Zenker’s Diverticulum: Zenker’s Diverticulum Zenker’s Diverticulum Esophagus Sac Myth 1: All posterior cervical diverticula are Zenker’s diverticula Killian-Jamieson Diverticulum • Originate below the CP muscle • Often project laterally • May account for 4/9 diverticula • Implications for treatment? – RLN – Recurrence Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Killian-Jamieson Diverticulum Sac Esophagus Forestier’s Syndrome • Dysphagia • Cervical Osteophytes (DISH) • Esophageal Diverticula – Traction Diffuse Idiopathic Skeletal Hypertrophy Post-traumatic Diverticulum Post-traumatic Diverticulum Management of Zenker’s Diverticula Diverticulotomy: External Approaches 1877 – 1st Attempted Drainage (Nicoladoni) 1884 – 1st Attempted Excision (Niehaus) 1886 – 1st Successful Excision (Wheeler) 1892 – Diverticulectomy with 1 Closure (Kocher) 1896 – Endoluminal Inversion of the Sac (Girard) 1917 – Diverticulopexy (Hill) 1936 – CP Myotomy with Diverticulotomy (Aubin) o Emil Theodor Kocher Myth 2: Recent technological advances have allowed endoscopic treatment of Zenker’s diverticula Diverticulotomy: Endoscopic Approaches 1917 – 1st Endoscopic Diathermy (Mosher) Harris P. Mosher Diverticulotomy: Endoscopic Approaches 1917 – 1st Endoscopic Diathermy (Mosher) 1960 – Endoscopic Diathermy (Dohlman) Gosta Dohlman Endoscopic Diverticulotomy Dohlman Esophagoscope Diverticulotomy: Endoscopic Approaches 1917 – 1st Endoscopic Diathermy (Mosher) 1960 – Endoscopic Diathermy (Dohlman) 1981 – Endoscopic CO2 Laser (van Overbeek) Geza Jako Endoscopic Diverticulotomy Challenges: – Dohlman procedure • Prone to recurrence • Occasional mediastinitis/death • Occasional stenosis – Laser Diverticulotomy • Variable success rates • Variable (some high) recurrence rates • Occasional fistula • Rare mediastinitis/death • Often multiple procedures Dohlman Esophagoscope Diverticulotomy: Endoscopic Approaches 1917 – 1st Endoscopic Diathermy (Mosher) 1960 – Endoscopic Diathermy (Dohlman) 1981 – Endoscopic CO2 Laser (van Overbeek) 1992 – Endoscopic KTP Laser (Kuhn) 1993 – Endoscopic GIA Stapler (Collard & MartinHisrch) USS EndoGIA 30 Stapler Staple-assisted (SA) Diverticulotomy Advantages: – Minimally invasive – Technically simple – Safe – Easy to repeat – Fast – Outpatient Staple-assisted (SA) Diverticulotomy Limitations: – Massive exposure – Dental injuries – Fails with small diverticula Kastenbauer-Wollenberg Diverticuloscope SA Diverticulotomy Limitations EndoGIA Stapler Limitations 27 mm 10 mm SA Diverticulotomy Limitations 28 mm Diverticulum SA Diverticulotomy Limitations 28 mm Diverticulum SA Diverticulotomy Limitations 28 mm Diverticulum SA Diverticulotomy Limitations 17 mm Diverticulum Minimal Length About 2-2.5 cm for Staple-assisted Diverticulotomy EndoGIA Stapler Modification Removal of Stapler Tip 27 mm 10 mm SA Diverticulotomy Limitations EndoStitch Technique for Staple Purchase SA Diverticulotomy Limitations EndoStitch Technique for Staple Purchase SA Diverticulotomy Limitations EndoStitch Technique for Staple Purchase Myth 3: If you make a hole in the pharynx and esophagus and don’t close it the patient will get mediastinitis and die Laser-assisted (LA) Diverticulotomy 1.8 cm Sub 2 cm Zenker’s Diverticulum Laser-assisted (LA) Diverticulotomy Laser-assisted (LA) Diverticulotomy Initial Cut Laser-assisted (LA) Diverticulotomy Laser-assisted (LA) Diverticulotomy Complete Division of Cricopharyngeus Laser-assisted (LA) Diverticulotomy Exposure of Esophageal Serosa LA Cricopharyngeal Myotomy Revision Following SA Diverticulotomy LA Cricopharyngeal Myotomy Revision Following SA Diverticulotomy Endoscopic Diverticulotomy OHSU Experience 2006-2010 70 Patients – 66 Endoscopic Procedures (94%) • 16 Stapler-assisted (24%) – 0 major complications – 1 dental injury • 50 Laser-assisted (76%) – 0 major complications – 3 SQ emphysema – 1 dental injury Myth 4: Cricopharyngeal dysfunction without Zenker’s diverticulum can only be treated via open approach Cricopharyngeal Dysfunction Cricopharyngeal Bar Cricopharyngeal Dysfunction Cricopharyngeal Dysfunction Cricopharyngeal Botox Injection Cricopharyngeal Dysfunction LA Cricopharyngeal Myotomy Cricopharyngeal Dysfunction Myth 5: Massive diverticula require an open approach to successfully manage them Massive Zenker’s Diverticulum Massive Zenker’s Diverticulum Massive Zenker’s Diverticulum Myth 6: All patients with Zenker’s diverticulum will swallow better following treatment of the Zenker’s diverticulum Paraesophageal Hernia Esophageal Dysmotility Esophageal Dysmotility Esophageal Dysmotility Esophageal Dysmotility Esophageal Dysmotility Thank You Mt.
