Objective: Reports of long-term outcomes for laparoscopic Heller myotomy (LHM) are scarce. In this work, outcomes of LHM for achalasia in patients who underwent surgery more than 10 years prior were investigated.
Methods: A cohort of patients treated with LHM and partial fundoplication for achalasia between 1993 and 1996 was followed for long-term outcomes, which were compared to baseline data at presentation.
Results: Thirty-two consecutive patients were identified, and follow-up information was obtained for 20 patients (62.5%). Mean follow-up was 11.2 years (range 10.3 to 12.3 years). Three patients (9.4%) were deceased (mean of 40 months postoperation). Of the 17 living patients, dysphagia was rated as severe in one (5.9%), mild to moderate in eight (47.1%), and absent in eight (47.1%). This was a significant improvement from preoperative scores in which dysphagia was rated as severe in 42.9%, mild to moderate in 57.1%, and absent in 0% (p < 0.05). In addition, 10-year dysphagia scores were unchanged from those at short-term follow-up (mean 27 months, p = 0.84). Other symptoms of heartburn, chest pain, voice symptoms, cough, and asthma were reported in fewer than 30% of patients at 10 years. Esophageal dilation following surgery was required in three patients, and two patients required repeat operations (esophagectomy in one patient, hiatal hernia in one patient). Satisfaction with the operation was reported by 16 patients (94.1%) at 10 years.
Conclusions: Most patients who underwent LHM with partial fundoplication reported satisfaction 10 years after the operation. A small number of patients required additional intervention. Dysphagia scores at 10 years were not different from those collected at short-term follow-up. Our data suggest that the efficacy of LHM is sustained at 10-year follow-up.
