Gastrostomy tract metastasis presenting as a large abdominal wall mass following percutaneous endoscopic gastrostomy for esophageal squamous cell carcinoma: a case report.

Percutaneous endoscopic gastrostomy (PEG) is a standard method for providing enteral access in patients with obstructive aerodigestive cancer. However, gastrostomy tract metastasis is a rare but devastating complication in patient with aerodigestive cancers who have undergone PEG tube placement. Due to its rarity, the standard therapeutic approach remains undefined. We report the case of an 83-year-old male who developed gastrostomy tract metastasis following pull-type PEG tube placement, presenting as a large abdominal wall mass detected during surveillance following definite chemoradiation for locally advanced thoracic esophageal squamous cell carcinoma. The patient underwent en bloc resection of the abdominal wall mass along with the PEG tube. The abdominal wall defect was closed using an inter-layer polyglactin mesh repair, followed by delayed split-thickness skin grafting.
