Killian-Jamieson Diverticulum: Cervical Oesophageal Diverticulum

Area of Science:

• Gastroenterology
• Otolaryngology
• Radiology

Background:

• Killian-Jamieson diverticulum is a rare congenital outpouching of the proximal cervical esophagus.
• It arises from the lateral esophageal wall, distinct from the more common Zenker's diverticulum.
• Understanding its anatomical origin is crucial for differential diagnosis.

Observation:

• This report details a case of a symptomatic Killian-Jamieson diverticulum.
• The patient presented with symptoms necessitating investigation.
• Clinical presentation and diagnostic imaging were key to identifying the condition.

Findings:

• Killian-Jamieson diverticulum originates between the cricopharyngeus and esophageal longitudinal muscle fibers.
• Radiological findings differentiate it from Zenker's diverticulum, which arises posteriorly.
• The case underscores the importance of recognizing subtle anatomical differences.

Implications:

• Accurate differentiation between Killian-Jamieson and Zenker's diverticulum is vital for appropriate management.
• This distinction impacts surgical or endoscopic treatment strategies.
• Enhanced awareness of Killian-Jamieson diverticulum improves diagnostic accuracy in esophageal outpouching cases.
