Mediastinoscopy-assisted Transhiatal Esophagectomy (MATHE) in End-stage Achalasia and Gastric Bypass: Technique and Early Results.

Introduction: Approximately 5% of patients who have undergone prior Heller myotomy and Roux en Y gastric bypass progress to end-stage achalasia (ESA). Surgical options for ESA are often limited to esophagectomy for management of severe dysphagia or life-threatening aspiration episodes. Mediastinoscopy-assisted transhiatal esophagectomy (MATHE) by a small left neck incision combined with an abdominal incision, without using a transthoracic approach, has been reported to reduce pulmonary complications. We herein present the first report of MATHE in 2 consecutive patients with ESA and gastric bypass.

Materials And Methods: Between August 2017 and September 2020, 2 patients who had undergone Heller myotomy and Roux en Y gastric bypass underwent MATHE for ESA. Transhiatal esophagectomy with mediastinoscopy-assisted dissection was performed. The remnant stomach was used as the conduit in both cases. The embedded Supplemental Digital Content 1 (http://links.lww.com/SLE/A269) reports our novel technique.

Results: Both cases were completed laparoscopically without conversion to laparotomy or thoracotomy. Median length of hospital stay was 9 days (range, 6 to 11 d). Postoperatively, 1 patient developed a cervical anastomotic leak, which healed with conservative management. No other major complications were observed.

Conclusions: MATHE can be safely performed in patients with a history of gastric bypass and ESA without requiring thoracoscopic mobilization of the esophagus. Further studies are required to validate reproducibility of our technique as an alternative to using a thoracic incision.
