The method of ultrasound examination of the walls of the colon

 

The method can be used in medicine, namely in gastroenterology. Injected into the cavity of the body of 0.9% NaCl solution. Assessment of the condition of the colon performed intraoperatively contact ultrasonic method on the opposite side from the performances of the sensor. The method allows to increase the accuracy and reliability of the study. 1 Il.

The invention relates to medicine, namely to methods for diagnosing lesions of the wall of the colon.

The known method transabdominal ultrasound examination of the large intestine in normal and pathological conditions (Mitkov centuries, Medvedev, M. C. Clinical guidelines for ultrasonic diagnosis", T 4, M, Vidar, 1997, s.; Lemeshko H. A. "Clinical Medicine", 1989, 6, 133-136 C.; Hata j, Haruma K. , "Abdom. Imaging." 1994, v. 19, 5, p. 403-408), has several disadvantages: 1) it is impossible to clearly differentiate sections of the colon, the layers of the wall of a hollow organ on the entire thickness along the intestine; 2) difficult topographical localization of pathologically modified area; 3) the inability to study the gut wall around the circumference; 4) the inability of the required duration of exposure for a full assessment of the condition of the walls of the body.

The closest in technical essence I am. Wisniewski C. A., "Visualization in the clinic", 1995, 6, S. 30-32; Mitkov centuries, Medvedev, M. C. Clinical guidelines for ultrasonic diagnosis", t 4, M, Vidar, 1997, 388 C.). The use of this method in the study of the walls of the colon has several disadvantages: 1) when using a linear sensor on hollow organs focal distance outside the walls of the intestine; 2) does not provide clear visualisiert adjacent to the sensor wall of the intestine; 3) the use of gels between the sensor and the wall of the intestine gives a distorted image on the monitor screen and the emergence of reverberations and artifacts; 4) the use of gels used intraoperatively, does not meet the requirements of modern surgery.

The aim of the invention is objectively accurate visualization of the walls of the colon, allowing to evaluate its structure.

The goal is to reach those that assess the state of the walls of the colon performed intraoperatively contact ultrasonic method on the opposite side from the performances of the sensor.

The method is as follows: In a patient with decompensated chronic colonic stasis at the time of surgical treatment produce the large intestine, into the cavity through which p is Tim linear transducer with a frequency of 9.0 MHz, with a pre-worn sterile rubber balloon, hold intraoperative ultrasound examination of the walls of the colon.

The sensor is put directly on the wall of the colon, and assessing the condition of the wall body hold on its opposite side (see echogram wall of the sigmoid colon of a patient).

An example of a specific application: the Patient K. 12 years with decompensated form of colostasis taken to the operating room. The child is planned operation Soave (removal of the affected part of the colon) in three stages. On opening the abdominal cavity in the revision emit the changed portion of the colon. Then through the previously inserted catheter into the colon injected with 0.9% NaCl solution. Linear multifrequency sensor equipped with a sterile rubber balloon at a frequency of 9.0 MHz device "Loc 700" conduct a study of the walls of the colon. When this sensor directly mounted on the wall of the colon, and the assessment of the morphological structure of the authority is carried out on the opposite from the sensor side.

The application of this method was carried out on 5 operations in children over decompensated forms of colostasis. Complications in early and late postoperative periods not OBS which allows you to perform a qualitative and quantitative assessment of wall layers of the colon on the circumference throughout the colon;
- does not require the use of various types of gels;
- enables testing under sterile conditions;
- the focal length of the sensor corresponds to the opposite wall of the colon;
- provides the ability to conduct research with different tilt sensor (poleposition, polyproylene);
compression on the wall of the body is minimal;
study is conducted non-invasive and atraumatic for the patient.


Claims

The method of ultrasound examination of the walls of the colon, including the introduction into the cavity of the body of 0.9% NaCl solution, characterized in that the evaluation of the condition of the colon performed intraoperatively contact ultrasonic method on the opposite side from the performances of the sensor.

SUBSTANCE: method involves examining eyeball and retrobulbary space by means of ultrasonic scanner. Ultrasonic gray scale orbit scanning is applied in real-time mode to determine ultrasonic eye reposition. Positive ultrasonic eye reposition is determined and normal state is diagnosed when recording mobile unchanged shape and free oscillation orbit tissue movements. Changes in shape, contours and size of the eyeball and immobility of orbit tissues being recorded, negative ultrasonic reposition is determined and solid full-tissue neoplasms and structures are diagnosed to occur.

EFFECT: high objectivity of received data; accelerated examination; high accuracy of differential diagnosis.

SUBSTANCE: method involves measuring uniform ampoule-like enlargement area of nerve trunk smoothly transforming itself into hypoechogenic formation with smooth distinct outline of no longitudinal striation echo-structure in longitudinal projection and enlarged rounded hypoechogenic region with changed echo-structure without granularity in transverse projection observed in visualizing the nerve trunk enlargement in transverse scanning mode. Area of zone proximally located 3-4 cm far from lesion region. Asymmetry coefficient is determined as ratio of the values. The coefficient value being greater than 2.4, terminal neuroma is diagnosed witnessing complete nerve rupture. When visualizing the single side nerve boundary enlargement in both projections with hypoechogenic zone of disturbed echogenicity structure and retained nerve segment unchanged at this level under asymmetry coefficient value being less than 2.4, lateral neuroma is diagnosed to be the case witnessing partial nerve rupture. When finding zone of linear striation echo-structure in longitudinal scanning mode and showing echo-structure granularity in transverse scanning mode not greater than 1.7 times proximal zone area 2-6 months later after the operation, fascicle nerve structure recovery in suture vicinity is considered to take place. Ampoule-like enlarged, hypoechogenic formation having partially disturbed inhomogeneous heterogeneous structure 1.7 times greater than proximal zone area being found within this period, intensive nerve trunk connective tissue elements proliferation and intratrunk neuroma is proved to be the case.
