Outcomes promote reoperative Heller myotomy for symptoms of achalasia.

BACKGROUND: Heller myotomy is accepted as first-line therapy for achalasia, yet for a small number of patients, symptoms persist or recur after myotomy. This study was undertaken to report our results with reoperative laparoscopic Heller myotomy for recurrent symptoms of achalasia. METHODS: We have undertaken laparoscopic Heller myotomy in 275 patients and reoperative myotomy in 12 patients for recurrent dysphagia, of which three had their initial myotomy undertaken by us. For each, studies prior to reoperative Heller myotomy documented a nonrelaxing lower esophageal sphincter without stricture. Patients scored symptoms before and after reoperative myotomy. RESULTS: Before reoperative myotomy, 75% underwent dilation and 42% underwent Botox injection. Ten of twelve reoperative myotomies were undertaken and completed laparoscopically. Median follow-up is 24.1 months (29.0 months + 25.89). Symptom frequency and severity scores improved significantly after reoperative myotomy. Frequency of vomiting and frequency and severity of heartburn were improved after reoperative myotomy, but not to a significant extent. However, they were not particularly notable prior to surgery, compared to obstructive symptoms, such as dysphagia. Excellent or good outcomes were reported in 73%, and notably, 91% stated that they would have the operation again after having been through the process firsthand and knowing their outcomes. CONCLUSION: Patient outcomes promote the application of reoperative Heller myotomy for recurrent or persistent symptoms of achalasia following Heller myotomy.

BMI affects presenting symptoms of achalasia and outcome after Heller myotomy.

BACKGROUND: Obesity has reached epidemic proportions in the United States and worldwide. The impact of obesity on health is increasingly recognized; however, its impact on achalasia has not been established. METHODS: The present study was undertaken to determine the impact of body mass index (BMI) on the symptoms of achalasia and outcome after myotomy. In our institution, 262 patients have undergone laparoscopic Heller myotomy and scored their symptoms before and after myotomy on a Likert scale (frequency: 0 = never to 10 = every time I eat/always; severity 0 = not bothersome to 10 = very bothersome). Patients were stratified by BMI > or = 30 kg/m2 or BMI < 30 kg/m2, and preoperative symptom scores and postmyotomy outcomes were compared. RESULTS: Patients with BMI > or = 30 had higher symptom scores for frequency of choking and vomiting before myotomy (p < 0.05). All symptom scores improved significantly after myotomy, except heartburn frequency and severity for patients with BMI > or = 30. By regression analysis, increasing BMI tended to exacerbate the frequency of choking and vomiting before myotomy and the frequency of heartburn after myotomy. Among the patients with BMI > or = 30 kg/m2, 73% reported excellent or good outcomes compared to 91% for patients with BMI < 30 kg/m2 (p = 0.02, Fisher's exact test). However, 96% of patients with BMI > or = 30 kg/m2, as well as 93% of patients with BMI < 30 kg/m2 would still elect to have the operation if they were asked to make the decision over again. CONCLUSIONS: Although some preoperative symptoms are exacerbated by elevated BMI, all symptoms of achalasia are improved with myotomy, even when undertaken for obese patients.
