Figure 1: Pseudorelaxation as a consequence of oesophageal shortening after a swallow in a patient with type II achalasia.

The dotted lines on the high-resolution manometry (HRM) plot depict the path of the lower oesophageal sphincter, taking it above the span of the eSleeve (a 'virtual sleeve' placed at the oesophogastric junction) and thereby simulating relaxation (tracing panel).
