    Abstract:
    PURPOSE: The purpose of this study was to compare demographics, symptoms, prior interventions, operation, and outcomes of patients who underwent Heller myotomy for esophageal motility disorders and epiphrenic diverticulectomy with Heller myotomy. METHODS: We identified all patients who underwent Heller myotomy for esophageal motility disorders with and without esophageal diverticulectomy over an 80-month period. Primary data points included patient demographics, presenting symptoms, prior intervention, high-resolution manometry, surgery performed with rate of laparoscopic, conversion to open, and open procedures; postoperative complications, and symptom resolution. RESULTS: Over the study period, 308 Heller esophagomyotomy operations were performed on 301 patients. Of these, 277 cases were without epiphrenic diverticula and 31 included diverticula. One patient with an asymptomatic epiphrenic diverticulum did not undergo surgery was included, for a total of 32 diverticula patients. Six patients in the non-diverticula group and 1 in the diverticula group required a second operation for recurrent symptoms or residual diverticulum. The diverticula group was significantly older, had different manometry findings, required more open operations, and had longer length of stay. The diverticula group had a lower frequency of patients with prior interventions, but similar postoperative leaks, higher overall postoperative complications, and no difference in reported symptomatic improvement. CONCLUSIONS: Esophageal diverticula patients have a unique profile compare to patients with non-diverticula motility disorders. Operations are more complex, with increased complication rate and a longer length of stay. In spite of this, there is no statistically significant difference in symptomatic outcomes between the groups.
