Postmyotomy dysphagia after laparoscopic surgery for achalasia.
OBJECTIVE
To determine predictive factors for postoperative dysphagia after laparoscopic myotomy for achalasia.


METHODS
Logistic regression was used to investigate the possible association between the response (postoperative dysphagia, with two levels: none/mild and moderate/severe) and several plausible predictive factors.


RESULTS
Eight patients experienced severe or moderate postoperative dysphagia. The logistic regression revealed that only the severity of preoperative dysphagia (with four levels: mild, moderate, severe, and liquid) was a marginally significant (P=0.0575) predictive factor for postoperative dysphagia.


CONCLUSIONS
The severity of postoperative dysphagia is strongly associated with preoperative dysphagia. Preoperative symptomatology can significantly impact patient outcome.
