Primary EGJ outflow obstruction has an unclear clinical significance. A substantial part of patients has unrelated symptoms, spontaneous symptom relief, or no stasis. Treated patients showed a beneficial response to botox injections. A small proportion develops achalasia at follow-up.

With HRM, the presence or absence and size of a hiatal hernia can be assessed with greater sensitivity than with endoscopy or radiography alone.

In these patients with incidental colonic focal activity undergoing PET/CT (the largest series published to date), malignancies had significantly higher SUVmax values than all other types of lesions. However, SUVmax could not distinguish between benign lesions and adenomas. In conclusion, all incidental findings in the colon should be further evaluated and lesions with SUVmax ≥11.4 should be evaluated without delay.
