Oesophageal intramural pseudodiverticulosis.

S Sabanathan, F D Salama, W E Morgan

|November 1, 1985

Summary

Oesophageal intramural pseudodiverticulosis involves small outpouchings in the esophagus, often causing dysphagia. Treatment focuses on underlying inflammation, as the pseudodiverticula rarely cause direct issues.

Background:

Oesophageal intramural pseudodiverticulosis (OIP) is a rare condition characterized by multiple flask-shaped outpouchings.
It predominantly affects individuals in their sixth and seventh decades, with a slight male predilection.

Observation:

Radiographic findings reveal small (1-4 mm) outpouchings with narrow necks connected to the esophageal lumen.
Pathological examination indicates these pseudodiverticula arise from dilated excretory ducts of submucous glands due to chronic inflammation.

Findings:

Dysphagia is the most common symptom, reported in 88% of cases.
Radiological narrowing of the esophagus was observed in 91% of patients, affecting various segments.

Implications:

The primary management strategy for OIP involves addressing the associated submucosal inflammation.
The pseudodiverticula themselves are typically asymptomatic and do not necessitate direct intervention.
