| [ Summary ] |
Malignant obstruction of the upper gastrointestinal tract causes disorder of nutrient ingestion and passage. Because these symptoms cause loss of body weight, adverse events of treatment, and worse prognoses, nutrition therapy is important for these patients. Percutaneous endoscopic gastrostomy (PEG) can be performed if a small diameter endoscope can pass through the stenotic region. Avoidance of hemorrhage, perforation, and implantation of the tumor into the abdominal wall should be considerations when performing PEG on head and neck cancer or esophageal cancer patients with stenotic regions. Gastrostomy is also performed to produce decompression for malignant obstruction of the upper gastrointestinal tract. If general condition is allowed to be performed, PEG may improve quality of life (QOL) of patients with malignant obstruction in the upper gastrointestinal tract. |
