Home enteral nutrition (HEN) refers to patients receiving enteral nutrition support therapy in a home environment. It is easily accepted by patients and their families because it saves hospital beds, reduces hospitalization costs, keeps patients together with their families, and helps improve patients’ quality of life. Percutaneous endoscopic placement of a gastrostomy / jejunostomy tube (Percutaneous endoscopic gastrostomy / jejunostomy PEG/J) is considered to be the preferred route for HEN because of its simplicity and low impact on patient appearance and comfort. From January 2004 to March 2007, a total of 36 patients underwent HEN via PEG/J with good results, which are reported below. From January 2004 to March 2007, 36 patients underwent HEN via PEG/J, including 21 males and 15 females, aged 22-81 (61.5±21.4) years, including 6 cases of radiation enteritis, 6 cases of inflammatory bowel disease, 5 cases of acute pancreatitis, 5 cases of cerebral infarction, 4 cases of gastrointestinal tumors, 4 cases of esophageal cancer, 2 cases of short bowel syndrome, 2 cases of nasopharyngeal cancer, 2 cases of esophagotracheal fistula. Nine of them had a history of abdominal surgery. PEG/J was administered during hospitalization, and all patients were discharged for HEN after the underlying disease was stabilized. 36 patients were treated with some commercial nutritional preparations plus homemade homogenate, and all had an energy level of about 1500 Kcal/day without re-hospitalization during the period. 2. Instrument materials GIF-XQ240 electronic gastroscope (Olympus, Japan), FG-42NR foreign body clamp (Olympus, Japan), percutaneous endoscopy-guided gastrostomy device (Fresenius Kabi, Germany and Nutricia, Netherlands), percutaneous endoscopy-guided small intestine stoma device (Fresenius Kabi, Germany and Nutricia, Netherlands), and percutaneous endoscopy-guided small intestine stoma device (Fresenius Kabi, Germany and Nutricia, Netherlands). Kabi, Germany and Nutricia, The Netherlands). 3. Placement method (1), PEG method: The classic drag-out method (Ponsky-Gauderer Technique) is used. Preoperatively, fasting, sedation and pain relief are given, and the gastroscope is entered into the gastric cavity and the stomach is inflated by gas injection. The skin of the upper abdomen is disinfected by the assistant, and the brightest spot in the left upper abdomen is identified by light pressure with the finger. The PEG tube is fixed to the wire, and the wire is pulled outside the abdominal skin incision so that the PEG tube enters the stomach through the oral cavity and is pulled out of the stomach cavity through the abdominal wall puncture; the PEG tube is pulled tightly so that the internal spacer presses the stomach wall against the abdominal wall to prevent bleeding, and then the PEG tube is fixed with a card outside the abdominal wall. (2), PEJ method: indirect method of percutaneous endoscopic jejunostomy, the whole process is completed in two steps: firstly, PEG is completed, then a jejunal nutrition tube is placed through the PEG tube, and with the assistance of gastroscopy, the catheter is grasped with foreign body clamp and the jejunal tube is gradually delivered into the upper jejunal segment. 4.The main observation indexes were weight, body mass index (BMI), plasma protein measurement and quality of life score ( Karnofsky behavioral status grading score KPS) in 36 patients at the time of PEG/J operation, complications, discharge and 2 months after performing HEN. 5. Statistical analysis All data were expressed as mean±standard deviation (mean±SD), and SPSS 12.0 statistical software was used for analysis and processing. Paired t-test was used to analyze the differences of patients’ indexes before and after HEN, with P<0.05 indicating significant differences and P<0.01 indicating highly significant differences. II. Results. 1. Operation: The average time of PEG operation (insertion of gastroscope, placement of catheter, and withdrawal of gastroscope) was (6.4±2.1) min, and the average time of PEJ was (15.7±4.2) min. The success rate of technical operation was 100%. Complications: There were no complications related to tube placement, and the incidence of complications after tube placement was 5.6% (2/36), which were 1 case of J-tube displacement and 1 case of J-tube blockage. 1 case of J-tube displacement was reinserted into the jejunostomy tube under endoscopic guidance, and 1 case of J-tube blockage was unblocked after repeated flushing with a guide wire and 5% sodium bicarbonate solution, and then soaked for 24 h. 3. Changes in nutritional status Changes in plasma protein: After 2 months of HEN, the patients' total plasma protein averaged 68.66 g/L, an increase of 8.11 g/L compared with that before support.
