A Japanese man, who had undergone a subtotal esophagectomy reconstructed with a gastric tube through an antesternal route for esophageal carcinoma 16 years previously, was admitted to our hospital because of an abdominal incisional hernia. The abdominal incisional hernia was in his upper abdomen and was difficult to push back into the intraabdominal cavity by hand. The hernia was successfully repaired by operation. We thus conclude that an abdominal incisional hernia is a rare but important late-phase complication occurring after an esophagectomy reconstructed with either an antesternal or retrosternal route, and an operation should be the treatment of choice.
