Utility of enteral nutrition via percutaneous transhepatic cholangiography drainage catheterization in late-stage malignant obstructive jaundice.

Objective: The purpose of this study was to explore the clinical benefits of establishing an enteral nutrition (EN) pathway via percutaneous transhepatic cholangiography drainage (PTCD) catheterization in patients with late-stage malignant obstructive jaundice (MOJ).Methods: We selected 30 patients diagnosed as having late-stage MOJ with malnutrition. A dual-lumen biliary-enteral nutrition tube was placed via PTCD along with a biliary stent implantation. Postoperative EN was provided, and we observed the time taken for tube placement, its success rate, complications, and therapeutic efficacy.Results: Tube placement was successful in all 30 patients with an average procedural time of 5.7 ± 1.4 min with no tube placement complications. Compared to preoperative measures, there was a significant improvement in postoperative jaundice reduction and nutritional indicators one month after the procedure (p < 0.05). Post-placement complications included tube perileakage in 5 cases, entero-biliary reflux in 4 cases, tube blockage in 6 cases, tube displacement in 4 cases, accidental tube removal in 3 cases, and tube replacement due to degradation in 8 cases, with tube retention time ranging from 42 to 314 days, averaging 124.7 ± 37.5 days. All patients achieved the parameters for effective home-based enteral nutrition with a noticeable improvement in their quality of life.Conclusion: In this study, we found that the technique of establishing an EN pathway via PTCD catheterization was minimally invasive, safe, and effective; the tube was easy to maintain; and patient compliance was high. It is, thus, suitable for long-term tube retention in patients with late-stage MOJ.

[Design and application of a new type of biliary-intestinal nutrient tube].

The establishment of a nutritional pathway is the premise and basis of nutritional therapy for patients with malignant tumor. The nasogastric tube, nasoenteric tube, and percutaneous endoscopic gastric/jejunostomy are commonly used clinical pathways for enteral nutrition (EN) therapy. However, these EN pathways are often difficult to establish in patients with malignant obstructive jaundice (MOJ) with pyloric or duodenum primary obstruction. For this reason, a new type biliary-intestinal nutrient tube placed through percutaneous transhepatic cholangiography drainage (PTCD) pathway was designed by the medical staff of hepatobiliary surgery department of Yinchuan First People's Hospital, and National Utility Model Patent of China were obtained (ZL 2020 2 0283951.5, ZL 2020 2 0288938.9). The new biliary-intestinal nutrient tube has two types: double-lumen tube and single-lumen tube, which consists of tube head, tube body, tail ring and developing ring. The double lumen tube realizes bile internal drainage and EN simultaneously through the double lumen structure of the tube body. The single-lumen tube is used for nutrient infusion after bile duct metal stent implantation, which is not limited by the type of nutrient solution. The tail ring of the two types of nutrient tube is placed in the upper jejunum to reduce retrograde infection and unexpected extubation. Compared with the prior art, the utility model has the advantages of simple structure, reasonable design, safe and effective placement through PTCD pathway, and opens up a new EN path for MOJ patients.
