The key to short-term enteral feeding in patients with gastroparesis is to deliver the nutrition beyond the pylorus. Endoscopic assisted methods allow the precise placement of the feeding tube to the small bowel. However, the main difficulty in association with these procedures is feeding-tube migration into the stomach during the withdrawal of the endoscope. We have developed an endoscopic method with a high success rate which prevents this problem. A reusable angiocatheter guidewire was threaded through the feeding tube, passing beyond the distal opening prior to the withdrawal of the scope. Counterpressure was applied to the feeding tube during the withdrawal of the endoscope. We have successfully placed feeding tubes in 22 out of 23 patients with no complications.
胃轻瘫患者短期肠内喂养的关键是将营养物质输送到幽门以外。内镜辅助方法可将喂养管精确放置到小肠。然而，这些操作的主要困难在于在内镜撤出过程中喂养管移入胃内。我们开发了一种成功率高的内镜方法来解决这个问题。在撤出内镜之前，将一根可重复使用的血管造影导管导丝穿过喂养管，使其超出远端开口。在内镜撤出过程中对喂养管施加反压。我们已成功为23例患者中的22例放置了喂养管，无并发症发生。
