To determine predictive factors for postoperative dysphagia after laparoscopic myotomy for achalasia.
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.
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.
The severity of postoperative dysphagia is strongly associated with preoperative dysphagia. Preoperative symptomatology can significantly impact patient outcome.
确定贲门失弛缓症腹腔镜肌切开术后吞咽困难的预测因素。
采用逻辑回归分析来研究反应（术后吞咽困难，分为两个等级：无/轻度和中度/重度）与几个可能的预测因素之间的潜在关联。
8例患者出现重度或中度术后吞咽困难。逻辑回归分析显示，仅术前吞咽困难的严重程度（分为四个等级：轻度、中度、重度和流食）是术后吞咽困难的一个边缘显著（P = 0.0575）预测因素。
术后吞咽困难的严重程度与术前吞咽困难密切相关。术前症状可显著影响患者预后。
