Summary

Zenker's diverticulum pathophysiology remains debated, with theories on muscle incoordination and cricopharyngeal issues. Myotomy and diverticulopexy offer the best treatment outcomes for this pharyngoesophageal disorder.

Area of Science:

  • Gastroenterology
  • Otolaryngology
  • Surgical Pathophysiology

Background:

  • Pharyngoesophageal (Zenker's) diverticulum etiology has been debated for over 200 years.
  • Multiple theories exist regarding the pathophysiology, including muscular incoordination, spasm, cricopharyngeal achalasia, gastroesophageal reflux, and neuromuscular abnormalities.
  • Understanding the exact cause is crucial for effective management strategies.

Purpose of the Study:

  • To provide a comprehensive overview of Zenker's diverticulum.
  • To review historical and current literature on the pathophysiology, clinical manifestations, diagnosis, and treatment options.
  • To clarify the ongoing debate surrounding the disorder's genesis.

Main Methods:

  • Systematic review of historical and current world literature.

  • Compilation and analysis of data on Zenker's diverticulum.
  • Synthesis of information on etiological theories, clinical presentation, diagnostic methods, and treatment modalities.

    • Main Results:

    • The exact etiology of Zenker's diverticulum is still not definitively established.
    • Various intrinsic and extrinsic factors have been proposed, but consensus remains elusive.
    • Myotomy and diverticulopexy are identified as yielding the most favorable treatment results.

    Conclusions:

    • Further research is needed to fully elucidate the pathophysiology of Zenker's diverticulum.
    • Despite ongoing debate, current treatment options like myotomy and diverticulopexy provide effective management.
    • This review consolidates existing knowledge to guide future understanding and clinical practice.
