We read with interest the article by Schuitenmaker et al1 that evaluated oesophageal pneumatic dilation (PD) for persistent dysphagia after antireflux surgery (ARS).
The authors concluded that PD is not more effective than sham procedure in patients with persistent dysphagia after laparoscopic fundoplication.
The therapeutic target of PD is the esogastric junction (EGJ) and its effect is theoretically explained by mechanical forces applied on an EGJ obstacle, being either cardial muscular in achalasia or extrinsic valve after antireflux fundoplication. But most of the patients included in the study (76%) did not have an EGJ outflow obstruction (EGJOO).
The realisation of an antireflux valve can lead to the development of inefficient oesophageal motility in nearly 20% of cases2 and the study of Schuitenmake et al reinforces the idea that post-ARS dysphagia is not necessarily related …
