Background
The standard Heller myotomy (SM) for achalasia extends 1 to 2 cm on to the stomach. The authors perform an extended myotomy (EM) (>3 cm) with the goal of reducing postoperative dysphagia. This study examines the long-term efficacy and durability of EM compared with SM.
Methods
Patients with achalasia who underwent a laparoscopic Heller myotomy were identified from a prospective database that includes symptom evaluation and results of esophageal functional studies. From September 1994 to August 1998, the authors performed SM with Dor fundoplication, and from September 1998 through 2003, they performed EM with Toupet fundoplication. In 2001, they performed a telephone survey of all available patients. This was repeated in 2005 for the EM group. The survey included scales of symptom frequency (0 [never], 1 [once per month], 2 [once per week], 3 [once per day], 4 [more than once per day]) and severity (0 [no symptoms] to 10 [symptoms equal to preoperative state]) as well as the need to undergo postoperative intervention for dysphagia.
Results
For this study, 52 patients underwent SM with Dor fundoplication (median follow-up period, 46 ± 24 months), and 63 patients underwent EM with Toupet fundoplication (median follow-up period, 45 ± 17 months. Postoperative dysphagia severity was significantly better in the EM group (4.8 ± 2.3 vs 3.1 ± 2.6; p < 0.005). There was no significant difference in postoperative heartburn frequency, esophageal acid exposure, or lower esophageal sphincter pressure. In the SM group, 9 patients (17%) required reintervention for dysphagia: 14 endoscopic interventions for 5 patients (10%) and reoperation for 4 patients. Three patients (5%) in the EM group required reintervention for dysphagia: one endoscopic intervention each and no reoperations (p < 0.05). A total of 30 patients in the EM group were contacted in both 2001 (median follow-up period, 19 ± 11 months) and 2005 (median follow-up period, 63 ± 10 months). There was no significant change over time in dysphagia severity (2.6 ± 1.9 vs 3.7 ± 2.0; p = 0.19).
Conclusions
For the treatment of achalasia, EM with Toupet fundoplication provides excellent durable dysphagia relief that is superior to SM with Dor fundoplication.
