To study the colonic motility, along with X-ray method, until recently widely used and ballonokimografichesky method, which complements the first in many respects.To perform duodenokineziografii in its simplest form it is used duodenal probe, which is soldered to the thin vinyl chloride tube, the distal end of which does not reach up to 1-2 cm olive.The end of the tube opens into the lumen of the thin-walled rubber balloon surrounding the duodenal tube for 5-6 cm. The edges of the can is fixed to the probe.
patient in a sitting position or lying on its right side on an empty stomach swallows duodenal probe.After the appearance of the probe under X-ray control screen bile produced olive finding places.When the probe enters the duodenum, it is set in a downward or horizontal bottom part of the colon.A peripheral hole vinyl chloride pipe, which is included in the lumen of a rubber balloon, are introduced 10 ml of air through a system of pipes and end it joins the Marey capsule.With ink on paper fixed on ky
probe periodically determined hydrostatic pressure in the duodenum;moreover, in the gut through various stimuli are administered: physiological saline, 3% hydrochloric acid solution, 33% magnesium sulfate solution.
Some authors registration bowel contractions produced by a strain gauge and recorder, the float system, inductive sensor and the other more modern methods.
RP Makos allocates duodenokineziogramme 2 types of waves: small, reproducing the rhythm and depth of intestinal contractions, and large - associated with muscle tone fluctuations.
EI Samson and NK Migovan noted that when duodenokineziografii they were able to detect such subtle movement disorders duodenal ulcer, as a change in her tone and the presence of different amplitudes of the waves, which, when X-rays did not show up.
OL Kolosov, EV Grishkevich et al.believe that the method of investigation of duodenal motility by using duodenokineziografii is a very sensitive and reliable, with which it is possible to take into account not only the force of muscle contraction, but the tone of the intestine and its reflex activity.VI Sokolov et al.using duodenokineziografii in patients with various diseases pancreatoduodenal areas identified various types of dysmotility of the duodenum.
Patients with duodenal ulcer, cholecystitis, pancreatitis and gastritis with dysmotility of the duodenum were observed both normal and elevated or reduced contraction of the intestinal wall.Enhanced contractile activity of the intestine was characteristic of the acute stage of the process, and reduced - indicative of chronic course and easing bowel tone.Among the patients of these groups can also be noted that in the presence of normal or even elevated rate cuts force gradually weakened and there are times when it is barely noticeable.
Comparing the data of X-ray studies and duodenokineziogramm, we can note their compliance.However, on the basis of duodenogrammy can give a more accurate assessment of the strength of the contractile ability of the gut wall and its back-up capability.
On the basis of our study we can say that in the presence of clinical and radiographic evidence of dysmotility of the duodenum by duodenokineziogrammy can specify the degree of the violation and the possibility of redundant colon.Integrated use of these methods of research allows you to make a right choice of the method of therapeutic effect on motor disorders duodenal ulcers, and in the operation - to take into account this condition.
