TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The prevalence of morbid obesity in the United States has been steadily increasing, and there is an established relationship between obesity and the risk of developing certain cancers. Patients who have undergone prior gastric bypass (GB) and present with newly diagnosed esophageal cancer represent a new and challenging cohort for surgical resection of their disease. We present our case series of consecutive patients with previous GB who underwent minimally invasive esophagectomy (MIE).', 'Retrospective review of consecutive patients with a history of GB who underwent a MIE for esophageal cancer between July 2010 and August 2012.', 'Five patients were identified with a mean age of 57 years. Mean follow-up was 9.1 months. Four patients had undergone laparoscopic GB, and 1 patient had an open GB. Two patients received neoadjuvant chemoradiation therapy for locally advanced disease. Minimally invasive procedures were thoracoscopic/laparoscopic esophagectomy with cervical anastomosis in 4 patients and colonic interposition in 1 patient. Mean operative time was 6 hours and 52 minutes. Median length of stay was 7 days. There was no mortality. Postoperative complications occurred in 3 patients and included pneumonia/respiratory failure, recurrent laryngeal nerve injury, and pyloric stenosis. All patients are alive and disease free at last follow-up.'] Is minimally invasive esophagectomy safe in patients with previous gastric bypass?
