Reconstruction for esophageal cancer after previous sleeve gastrectomy technical challenges in a case report.

Obesity is a major risk factor for cancer. While bariatric surgery reduces obesity-related risks, it may introduce challenges in surgical oncology. We report a case of esophageal carcinoma in a patient with a history of laparoscopic sleeve gastrectomy (LSG), successfully managed with a completely laparoscopic-thoracoscopic Ivor-Lewis esophagectomy using the remnant stomach for reconstruction. Despite LSG-related vascular alterations, collateral circulation appeared sufficient to support conduit perfusion, suggesting that this approach is feasible in selected patients.
