Thoracic Esophageal Diverticula: A 15-Year Experience of Minimally Invasive Surgical Management.

Abstract

Thoracic esophageal diverticula are uncommon, and controversies exist regarding their management. The objective of this study was to evaluate the outcomes of a relatively large cohort of patients with thoracic esophageal diverticula treated with minimally invasive surgical techniques. We conducted a retrospective review of patients who underwent minimally invasive surgical treatment for symptomatic esophageal diverticula during a 15-year period. The primary end point was 30-day mortality. In addition, we evaluated the morbidity, improvement in dysphagia (score: 1, best to 5, worst), and quality of life (Gastroesophageal Reflux Disease-Health-Related Quality of Life score: 0, best to 50, most symptoms). Fifty-seven patients underwent minimally invasive surgical treatment of symptomatic thoracic esophageal diverticula. The most common symptom was dysphagia (45 of 57; 79%). A motility disorder or distal mechanical obstruction was identified in 49 patients (86%). Approaches used included video-assisted thoracoscopic surgery (n = 33), laparoscopy (n = 18), and combined video-assisted thoracoscopic surgery and laparoscopy (n = 6). The most common procedure performed was diverticulectomy and myotomy (47 of 57 patients; 82.5%). The 30-day mortality was 0%. There were 4 patients (7%) with postoperative leaks requiring reoperation. During follow-up, the median dysphagia score improved from 3 to 1 (p < 0.001). The median Gastroesophageal Reflux Disease-Health-Related Quality of Life score after surgery was 5 (excellent). A minimally invasive surgical approach for the management of thoracic esophageal diverticula is safe and effective during intermediate-term follow-up when performed by surgeons experienced in esophageal surgery and minimally invasive techniques. Further follow-up is required to assess the durability of these results. The optimal approach and procedures performed should be determined on an individualized basis after a thorough investigation.
