Laparoscopic Heller myotomy with Dor fundoplication for achalasia: long-term outcomes and effect on chest pain.
The aim of the present study was to evaluate the long-term outcomes of laparoscopic Heller myotomy with Dor fundoplication (LHD) and its effect on chest pain. Between June 1995 and August 2009, a total of 35 patients with achalasia underwent an LHD. The symptom scores were calculated by combining the frequency and the severity. Pre- and postoperative evaluations included symptom score, radiology, manometry, and 24-hour pH manometry. Median total symptom score was significantly lower than the preoperative score (19 vs 4, P < 0.001) at a median follow-up of 94 months. Among the 35 patients, 18 (51%) had chest pain. The frequency of chest pain was similar for the pre- and postoperative scores, but the severity tended to be less. Median esophageal diameter (5.4 cm vs 3.5 cm, P < 0.001) and lower esophageal sphincter pressure (41 mmHg vs 8.9 mmHg, P < 0.001) were significantly reduced after surgery. Median age, duration of symptoms, esophageal diameter, and lower esophageal sphincter pressure were similar between patients with and without chest pain prior to surgery. No significant differences were observed between the two groups in terms of amplitude, duration, and frequency of contractions from the findings of postoperative 24-hour esophageal manometry. Chest pain resolved in three patients (17%) and improved in seven patients (39%) after surgery. LHD can durably relieve achalasic symptoms of both dysphagia and regurgitation, and it can be considered the surgical procedure of choice. However, achalasic chest pain does not always seem to be related with patient characteristics and manometric findings.
