Technique of resection of esophageal adenocarcinoma after Roux-en-Y gastric bypass and literature review of esophagogastric tumors after bariatric procedures.

BACKGROUND: The number of bariatric procedures has continued to increase worldwide. However, experience with tumors arising in the esophagus or stomach after gastric bypass is lacking. We report our technique for curative resection of esophageal adenocarcinoma in a patient who had undergone previous gastric bypass and review the reported data on esophagogastric tumors after bariatric surgery.
METHODS: We have described the operative details of esophagectomy after gastric bypass and reviewed the published data regarding type of bariatric surgery, gender predilection, presentation, symptom duration, cancer stage, and prognosis of patients with esophagogastric tumors occurring after bariatric surgery.
RESULTS: Only 22 esophagogastric tumors have been reported so far after bariatric surgery. The majority of them are locally advanced or metastatic at presentation.
CONCLUSION: Esophagogastric tumors after bariatric surgery are uncommon. This operative technique pays particular attention to the altered anatomy, dissection of the gastric pouch, and preservation of the blood supply to the excluded stomach. This technique can also be applied to manage tumors arising in the gastric pouch after previous gastric bypass. Close collaboration with the bariatric surgeon during surgery is essential to achieve a successful oncologic outcome in this subset of patients.
