Duodenal catheterization is the procedure of inserting a tube through the nose or through the mouth into the duodenum to collect samples, feed by bringing food down to the duodenum when the stomach has problems such as tumors causing incomplete stricture. pyloric orifice or as part of the manipulation of other procedures. To ensure accuracy, duodenal catheterization is usually performed under C-ARM guidance.

1. What is C-ARM-guided duodenal catheterization?

Duodenal catheterization is the procedure of inserting a tube through the nose or through the mouth into the duodenum to collect samples for testing and feeding, this can also be part of the manipulation of other procedures. Placing a duodenal catheter is simple, but requires experience and ingenuity of the performer. For accurate duodenal catheterization, this procedure is usually performed under the guidance of a fluorescent screen (C-ARM).
C-ARM is an X-ray based imaging device that enhances images in the operating room. The device has a C-arm shape, so it is named C-ARM. This is a non-invasive device that provides high resolution X-ray images to help doctors monitor the progress of the surgical procedure and make appropriate decisions, ensuring safety during and after surgery.

2. In which cases is C-ARM-guided duodenal catheterization indicated?

Catheter placement under C-ARM guidelines is indicated in the following cases:
Take a sample of bile or pancreatic juice for testing. Inject the dewormer into the duodenum. Feeding through a duodenal tube. Water injection in Multislice Computer Tomography (MSCT) of the small intestine. This technique is contraindicated in patients with pyloric stenosis or duodenal ulcer.

3. Procedure for performing duodenal catheterization under the guidance of C-ARM . fluorescent screen

3.1. Preparing for the procedure, including 01 doctor and 01 support nurse. In terms of facilities, need a C-ARM machine and a duodenal catheter (using a contrast-barred first part of the duodenal catheter).
Regarding patient preparation, before the procedure, the doctor will examine and instruct the patient to fast for 4-6 hours before the procedure.

3.2. Steps to perform duodenal catheterization under C-ARM guidance. . Observe the image from the C-ARM machine to see if the tip of the catheter has entered the antrum or not. If the catheter has not entered the antrum, the doctor may have the patient stand up and walk for a while, then check again. If the catheter has entered the antrum, proceed to insert the tube through the pyloric orifice into the duodenum. Locate the tube placement through images from the C-ARM machine. If the catheter has entered the duodenum, proceed to fix the catheter on the skin. If a duodenal catheter is placed for monitoring or feeding purposes, the catheter will be left in place for some time. If a duodenal catheter is part of another procedure, the catheter will be removed after the procedure is complete.
3.3. Possible complications when inserting a duodenal catheter When inserting a duodenal catheter, the possible complications are:
Misplaced catheterization into the trachea Bleeding: usually occurs on the background of the lining of the gastrointestinal tract. previous injury due to ulceration or cancer. To limit these complications, during the procedure, the doctor should carefully monitor the guided images from the C-ARM enhanced fluorescent screen. At the same time, carefully monitor the patient during and after the procedure.
