useful for enteral feeding and bowel decompression. PTEG is creating via the cervical esophagus
therefore this is useful especially with massive ascites (including malignant ascites), gastric cancer,
post gastrectomy state. Of course this is one of useful procedure of palliative treatment for the patient

usefulness (how improve the patients’ nasopharyngeal discomfort) and safety for the malignant bowel
obstruction and defined it improved the patients’ nasopharyngeal discomfort without severe
