Presented at the Forty-fifth Annual Meeting of The Society of Thoracic Surgeons, San Francisco, CA, Jan 26–28, 2009.

Background: Esophagectomy is indicated occasionally for the treatment of patients with refractory gastroesophageal reflux disease (GERD) or recurrent hiatus hernia. The purpose of this study was to evaluate the impact of previous gastroesophageal operations on outcomes after esophagectomy for recurrent GERD or hiatus hernia.

Methods: Using a prospectively accumulated database, a retrospective review was performed to identify patients undergoing esophagectomy for complicated GERD or hiatus hernia. Mortality, perioperative and functional outcomes, and need for reoperation were evaluated, assessing esophagectomy patients who had undergone prior operations for GERD or hiatus hernia.

Results: Of 258 patients with GERD or hiatus hernia undergoing esophagectomy, 104 had undergone a previous operation, with a median interval to esophagectomy of 28 months. Transhiatal resection was accomplished in fewer patients undergoing reoperation (87 of 104 versus 151 of 154; p < 0.005). A gastric conduit was used as an esophageal replacement in fewer patients with previous operation(s) (89 of 104 versus 150 of 154; p < 0.005). Esophagectomy patients with a history of prior gastroesophageal surgery, as compared with those without, sustained more blood loss and were more likely to require reoperation, and fewer reported good to excellent swallowing function (p < 0.05). There was no difference in the occurrence of anastomotic leak.

Conclusions: Esophagectomy in patients who have undergone prior operations for either GERD or hiatus hernia can be accomplished without thoracotomy and with satisfactory intermediate-term quality of life. Such patients should be evaluated and prepared for the use of alternative conduits should the remobilized stomach prove to be an unsatisfactory esophageal substitute at the time of esophagectomy.
