What is duodenal sounding

Duodenal sounding is used to diagnose and treat liver diseases, as well as bile ducts. The purpose of the procedure is to obtain the contents of duodenum (duodenum - duodenum) for investigation. It consists primarily of the secretion of the pancreas together with bile.

With the help of this study, a conclusion is also made about the operability and condition of the following internal organs:

• duodenum,
• Gall bladder ,
• Bile ducts,
• pancreas,
• liver.

In some cases, the pathologies of the above organs are revealed.

Duodenal sounding is performed for therapeutic purposes. In this case, the appropriate medications are administered through a special duodenal probe.

Duodenal probe

It is a sterile thin rubber tube, 1.5 meters long with a lumen diameter of 2.3 millimeters. At the end of the tube, the tube contains a metal olive with holes hollowed inside.

Duodenal sounding. Preparation, process

• The patient must be prepared psychologically, convincing him of the complete safety of the manipulations.
• Duodenal probing to the patient is carried out in a special room on an empty stomach. On the eve of the patient taking the subcutaneous or inside the solution of atropine, the dinner should be light, excluding products that provoke gas formation. This is black bread, potatoes, milk.
• The patient should rinse the mouth with an antiseptic solution.
• On the duodenal probe, the distance from the teeth to the navel of the patient in the standing position is noted.
• Olive, which can be lubricated with glycerin, is put in the mouth of the patient.
• It is pushed through the root of the tongue and the patient, relaxing and breathing deeply, produces swallowing movements.
• Thus, the probe is gradually swallowed up to the passage of the olive into the duodenum. Usually it goes there for one to two hours.
• The patient is placed on the right side, and with the help of the inserted probe, a portion "A" of the duodenal contents is pumped out into the pre-prepared tube. It is mixed with the bile juice of duodenum. The color of the liquid is usually light yellow.
• A special stimulant is injected through the duodenal probe and a "B" portion is given in a short time (5-10 minutes). It is a concentrated dark, olive bile from the gallbladder. If the contents can not be taken within a quarter of an hour, the stimulus is reintroduced.
• After complete emptying of the gallbladder, a clear liquid is obtained, which is a mixture of intestinal juice and hepatic bile - a portion of "C".

All bile portions can not always be obtained even in completely healthy people, because of the absence of a reflex when introducing an irritant. However, in some cases, duodenal sounding can be used in a five-phase method involving 5 phases of bile secretion.

Duodenal sounding chromatic

• Approximately twenty hours before the procedure of sounding, the patient is given a gelatin capsule of methylene blue. This is done two hours later (but not earlier) after a light dinner.
• In the morning, traditional duodenal sounding is performed. In this case, the bile is colored blue. This is because methylene blue is discolored when passing through into the hepatic bile through the blood. When entering the gallbladder, its color is restored again, staining the bile.

With this method, it is possible to accurately determine the number of gall bladder, as well as a number of other studies. This method of diagnosing the biliary tract is very effective.

Probably, also for the purpose of treating parasitosis, the introduction of antibiotics through the probe, when duodenal sounding is performed. The parasites are directly affected by the corresponding drugs.

In children, the technique and procedure for sounding are the same, taking into account age specificity.
