Description
Summary:Background Relieving esophagogastric junction (EGJ) obstruction has been the focus of treatment for achalasia cardia. The recovery of peristalsis has been an elusive goal. Studies analyzing post-intervention peristaltic recovery have several limitations such as the use of conventional manometry or lack of standard definitions of peristalsis. Accordingly, we undertook this study to analyze frequency and pattern of peristaltic recovery following treatment for achalasia cardia on high-resolution manometry (HRM) and standard Chicago definition of peristalsis. Methods Pre and post-intervention HRM records of 71 treatment-naive patients diagnosed as achalasia cardia were retrospectively analyzed. Records with pre and post-intervention HRM on different systems (e.g. solid state and water perfusion) and those with inadequate information were excluded. All HRMs were interpreted as per Chicago classification version 3.0. After pneumatic dilation (PD) or laparoscopic Heller’s myotomy (LHM), pseudorecovery of peristalsis was defined as any contraction at least 3 cm in length along 20 mmHg isobaric contour with a distal latency of less than 4.5 seconds. True recovery and premature contractions were defined by standard Chicago classification v3.0 criteria. Results Change in diagnosis was observed in 38 of 71 (53.5%) patients after intervention. While pseudo-peristaltic recovery occurred in 11 of 71 (15.5%) patients, only three (4.2%) had a true recovery. Another nine (12.7%) patients showed new premature contractions. Conclusion True peristaltic recovery is uncommon in achalasia cardia following intervention, particularly PD. Pseudo-peristaltic recovery is more common. Further research is warranted on this issue.
