Non-surgical jejunostomy, including endoscopic and iconographic guided jejunostomy is an important method for enteral nutrition access establishment, which is especially beneficial to the patients with gastrectomy, high risk of aspiration or gastric dysmotility. “Chinese experts consensus on nutritional access of cancer patients (2018)”, which was released by the the Nutritional Access Group of Chinese Society for Oncological Nutrition and Supportive Care, suggested several recommendations on nonsurgical jejunostomy. Here we provide further related information for the recommendations , including the technical characteristics of percutaneous endoscopic gastrojejunostomy and direct percutaneous endoscopic jejunostomy, the advanced modification on localization techniques of tube placement and puncturing site selection, the updated evidences on clinical application of sonographic/ radiologic jejunostomy and combined techniques. We also previewed related literatures and interpret  the optional strategy of percutaneous endoscopic gastrojejunostomy or direct percutaneous endoscopic jejunostomy in patients who are unsuitable for percutaneous gastrostomy, the technological difficulties and  resolutions in direct percutaneous endoscopic jejunostomy, the technical progress and clinical significance of radiologic application in non-surgical jejunostomy, and the positive role of single-balloon enteroscopy or double-balloon enteroscopy in improving the success rate of direct percutaneous endoscopic jejunostomy.
