Description

Device for endoscopic determination of the diameter of the anastomosis

The proposed utility model relates to medicine, namely to endoscopy and can be used when performing diagnostic studies in gastroenterological patients.

In endoscopy of the gastrointestinal tract, determining the size of the lumen of the studied internal organs is important. (Pantsirev Yu.M., Gallinger Yu.I. Operative endoscopy of the gastrointestinal tract. // Moscow. - 1984.-192 p.). Determination of the internal diameter of the cardia, pylorus, anastomosis is crucial for the diagnosis of pathology and the selection of rational treatment tactics.

Known devices for determining the exact size of the lumen of the gastrointestinal tract, based on x-ray research methods. Carrying out similar radiological methods for some motor evacuation dysfunctions do not allow obtaining true data on the true size of the lumen of the internal organs, are associated with significant radiation exposure and are very complex and rather laborious. And finally, with gastroenterological diseases, radiological methods imply further endoscopic examination, as a diagnostically more informative one (Guidelines for clinical endoscopy under the editorship of academician V.S. Savelyev, professor V.M.Buyanov, professor G.I. Lukomsky M. “Medicine 1985 , 543 p.).

Taking into account the optical properties of the video system (endoscope-video camera-monitor), depending on the distance from the endoscope to the object and the angle of view, the dimensions of the anatomical structures on the monitor are determined visually by measuring and comparing them with the size of the endoscopic instrument on the monitor screen (for example, with the size of the jaw biopsy w; ips or by the size of the injector, clips, etc.). Obviously, the subjective assessment of the compared sizes, optical distortions cannot

reflect the true dimensions of the anatomical structures.

Prototin is a bougie that is inserted through an endoscope and based on the known diameter of the anastomosis, the diameter of the anastomosis is determined (Guidelines for Clinical Endoscopy, edited by Academician V.S. Savelyev, Professor V.M.Buyanov, Professor G.I. Lukomsky M .: “Medicine 1985, p. 147). The use of bougie of known diameter is associated with inevitable trauma during narrowing of the lumen of the organ.

The technical result of the proposed utility model is to increase the accuracy of determination while reducing the morbidity of manipulations during endoscopic examinations.

In FIG. 1 shows the proposed device.

A device for determining the diameter of the anastomosis is a probe 1 equipped with an elastic balloon 2 in the shape of a ball.

The proposed device is used as follows: it is introduced into the biopsy channel 3 of the endoscope, while the balloon is installed in the lumen of the measured anastomosis. A graduated measuring device (a syringe connected to a pressure gauge) inflates the ball with a liquid of known density (we used water) under constant pressure until the ball is inflated with liquid (without it)

deformations, which is controlled visually during endoscopy) will not completely block the lumen of the anastomosis. The diameter of the anastomosis is calculated by the formula:, where Ddiameter, Y is the volume of the ball, n is the number "pi.

Using this device in 36 patients, we were able to determine the true dimensions of the internal dimers of the intestinal ankles without additional manipulations. The specified device also allows measurements in the lumen of the entire gastrointestinal tract, however, the presence of sphincter formations (cardiac, pyloric pulp) may, depending on

functional state (spasm, gaping) give different measurement results. The results of measuring the diameter of postoperative gastrointestinal anastomoses are always constant and exactly consistent with intraoperative and autopsy data. Clinical example. Patient K., 34 years old (medical history No. 98995), was admitted to the hospital with complaints of abdominal pain, vomiting, weight loss. A history of surgery is a resection of the stomach for peptic ulcer. Clinical and instrumental examination established the diagnosis - illness of the operated stomach, peptic ulcer anastomosis, stenosis of gastrogastroanastomosis. An endoscopy was performed, a probe equipped with a balloon-shaped balloon was carried out into the biopsy channel of the endoscope. The balloon is installed in the lumen of the measured anastomosis. A graduated measuring device (a syringe connected to a pressure gauge) inflated the ball with water under constant pressure (100 cm water) until the balloon inflated with liquid completely blocked the anastomotic lumen. The volume of fluid introduced into the balloon was 2.093 cm.

The diameter of the anastomosis is calculated by the formula: where D is the diameter, V is the volume of the ball, number "pi, and in this case we will be 1.0 cm. The patient is operated on, the stomach is resected with an anastomosis. The postoperative course is smooth. Discharged from the hospital on the 9th day after surgery with recovery. In autopsy material, the diameter of the resected anastomosis was 1.0 cm.
