Preoperative manometry is not a predictor of postoperative dysphagia in chagasic achalasia

Background: Heller’s myotomy is probably the most performed operation for the treatment of achalasia. Although excellent and good results are usually achieved, some predictive factors for poor surgical outcome should be studied. Few papers have studied the correlation between preoperatory esophageal manometry and surgical outcome. Aim: This study examined a total of 28 patients with Chagas’ disease esophagopathy that submitted to an esophageal cardiomyotomy and anterolateral partial fundoplication (Heller–Pinotti procedure). Methods: Surgical outcomes were assessed subjectively based on the healing of dysphagia. Results: Excellent and good results (absent or sporadic dysphagia) were found in group A; moderate and poor results (mild or incapacitating dysphagia) were found in group B. Conclusion: Resting pressure of the upper and lower esophageal sphincter, and amplitude and propagation of peristalsis of the esophageal body did not correlate with surgical outcome suggesting that preoperative esophageal manometry is not a predictor of dysphagia after esophageal cardiomyotomy and fundoplication in chagasic patients.
