A CASE OF PYOTHORAX AND CHYLOTHORAX FOLLOWING ENDOSCOPIC SUBMUCOSAL DISSECTION FOR GASTRIC TUBE CANCER

Abstract

A 73-year-old male underwent subtotal esophagectomy and posterior mediastinal gastric tube reconstruction for esophageal cancer. Six years after surgery, he underwent endoscopic submucosal dissection (ESD) for early-stage gastric tube cancer. There were no signs of perforation or any other coincidental complication ; however, fever and right pleural effusion developed the following day, indicating the possibility of mediastinitis or pleuritis. Although his condition improved with fasting and antibiotic medication, fever recurred 3 weeks after the ESD, and he had to be re-hospitalized. Right pyothorax was observed, and chest drainage revealed chylous fluid. The patient recovered with conservative treatment after drainage, and he was discharged 1.5 months later. This is the first case report of pyothorax and chylothorax after ESD for gastric tube cancer.
