Purpose: Although endoscopic staple-assisted esophagodiverticulostomy (ESED) has become the initial treatment of choice for most patients with Zenker's diverticulum (ZD), anatomical restraints prevent its use in all cases. We describe an endoscopic approach for treating ZD using the harmonic scalpel, which can be used in certain cases where diverticulum anatomy precludes ESED.
Materials And Methods: Medical records of 7 consecutive patients who underwent endoscopic repair of ZD using the harmonic scalpel (Harmonic Ace, Ethicon Endo-Surgery, Inc, Cincinnati, OH) were reviewed. Data collected included demographics, symptoms, surgical details, complications, and postoperative outcomes. Main outcome measures were time to resumption of oral diet, symptom resolution, and complications.
Results: All patients (N = 7) who underwent endoscopic repair of ZD using the harmonic scalpel resumed an oral diet at initial follow-up visit after surgery (mean, 7 days; range, 4-9 days) and rated their symptoms as being completely resolved at subsequent follow-up (mean, 4 months; range, 1.5-8 months). There were no complications.
Conclusions: Endoscopic repair of ZD using the ultrasonic cutting shears is a safe and efficacious procedure that allows for endoscopic treatment in certain cases that cannot be treated by ESED. Further study is warranted in larger series to determine efficacy and safety compared with established endoscopic techniques.
