ABSTRACT

Because of tumor compression,blockage,and anti-tumor treatment,patients with head and neck cancer or esophagus cancer often have many adverse reactions,such as dysphagia,loss of appetite,taste disappeared and so on,leading to malnutrition and weight loss,which requires nutritional support treatment.Percutaneous endoscopic gastrostomy(PEG) is a simple technology widely used in clinic which has less complications can improve patients'nutritional status and quality of life.However,the phenomenon of fistula metastasis is easy to be neglected due to lower incidence.the pathogenesis of fistula metastasis is unclear.The occurrence of complications can be reduced by preoperative radiotherapy and chemotherapy,overtubes,povidone iodine and a good fistula care.Surgery,interstitial brachytherapy and radiofrequency ablation therapy may be effective.This article will review the pathogenesis,prevention and prognosis of tumor metastasis after percutaneous endoscopic gastrostomy.
