Laparoscopic transhiatal esophagectomy for esophageal adenocarcinoma identified at laparoscopic Roux-en-Y gastric bypass

• Preoperative endoscopy is indicated bariatric patients with history of gastroesophageal reflux.
• Laparoscopic transhiatal esophagectomy can be safely performed in patient with history of Roux-en-Y gastric bypass.
• The gastric remnant provides a good conduit for reconstruction following esophagectomy in patients with a previous Roux-en-Y gastric bypass.

IntroductionMore than one third of Americans are obese. Obesity is a risk factor for gastroesophageal reflux disease (GERD) and esophageal adenocarcinoma (EA). The only durable treatment for morbid obesity and its comorbid conditions is bariatric surgery. There is no consensus among bariatric surgeons, however, regarding the role of preoperative screening upper endoscopy in bariatric surgery.Presentation of caseTwo cases of incidental EA were identified by completion EGD following laparoscopic Roux-en-Y gastric bypass (LRYGB). EGD was done for anastomotic surveillance and provocative leak testing. Esophageal masses were identified and biopsies demonstrated adenocarcinoma. In both cases a laparoscopic transhiatal esophagectomy (LTHE) was completed using the gastric remnant as conduit; the biliopancreatic limb was divided proximal to the jejunojejunostomy and anastomosed to the proximal roux limb to complete the reconstruction.DiscussionObesity is a risk factor for GERD and EA. The role of EGD prior to bariatric surgery is unclear. Studies have demonstrated routine EGD prior to bariatric surgery may diagnose foregut pathology; however, few of the findings alter the planned treatment. The cost effectiveness of this strategy is questionable. There are reports of EA developing after bariatric surgery; however, we found no previous case reports of EA identified at LRYGB.ConclusionOur institution has opted for selective preoperative endoscopy in patients with preoperative gastrointestinal symptoms. In post gastric bypass patients LTHE can be performed with good results.
