Background: The endoscopic nasojejunal (NJ) placement plays a pivotal role in the nutritional support of critically ill patients. However, the conventional endoscopy-guided tube insertion method presents issues of excessive procedural duration. We have enhanced the traditional endoscopy-guided catheter placement method, enabling a faster and more convenient catheter insertion.
Methods: We improved the traditional endoscopically guided technique by incorporating an extra silk thread knot at the 25 cm mark on the jejunal segment of the NJ tube to assist endoscopists in accurate tube placement. We conducted the improved NJ tube placement on critically ill patients in need of enteral nutrition (EN). Laboratory data were retrospectively collected before and after the 7-day period of NJ tube placement and EN treatment to evaluate the effectiveness and safety of the improved method.
Results: A total of 88 critically ill patients, with an average age of 59.6±15.5 years, and a male ratio of 86.4%, who underwent the improved NJ tube placement method were enrolled into analysis finally, achieving a 100% success rate of NJ tube insertion. The average time for tube insertion was 5.9±2.2 min, with a mean insertion depth of 108.8±12.5 cm. The EN tolerance score was 0.79±0.98. Following 7 days of EN therapy, the patients showed significant improvement in serum albumin levels compared to baseline (36.42 vs. 33.66 g/L, P<0.001).
Conclusions: The improved endoscopically guided NJ tube placement technique is a rapid and safe procedure with excellent patient tolerance. It significantly improves the nutritional status of critically ill patients and facilitates the administration of EN, which requires further validation through randomized controlled trials.
