Reconstruction of the esophagus of patients with middle thoracic esophageal carcinoma using the remnant stomach following Billroth II gastrectomy.

It seems impossible to reconstruct the esophagus of patients with middle thoracic esophageal carcinoma with a history of distal gastrectomy using the remnant stomach. Although surgeons have made multiple efforts to reconstruct the esophagus using the remnant stomach, it can only be successfully used in cases of lower thoracic esophageal cancer. Additionally, the surgery is more complex than traditional esophagogastrostomy due to challenges including mobilization of the remnant stomach with the spleen and transposition of the pancreatic tail into the left hemithorax. Our operation proved that the remnant stomach, which we named as the completely mobilized remnant stomach after dissection of the feeding vessels, remained viable. We successfully integrated the completely mobilized remnant stomach in the reconstruction of the lower thoracic esophageal tract and then integrated it in Ivor Lewis esophagogastrostomy. We describe this new alternative surgical technique for the treatment of middle thoracic esophageal carcinoma in patients with a history of distal gastrectomy in this study. Clinical data of 23 patients from 2008 to 2019 were retrospectively analyzed. All patients underwent the Ivor Lewis procedure. All remaining vessels of the remnant stomach were dissected at their origins, and Roux-en-Y reconstruction or Braun anastomosis was performed. After esophagectomy during right thoracotomy, anastomosis of the remnant stomach and esophagus was performed. Two-field lymph node dissections were performed. There was no case of necrosis of the remnant stomach or of perioperative death. Serious complications included anastomotic leak in three cases, afferent-efferent loop syndrome in one, and anastomotic stricture in two. Application of the completely mobilized remnant stomach in Ivor Lewis esophagogastrostomy is feasible, and the surgical procedure is similar to that of normal esophagogastrostomy.
