FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to abdominal surgery and gastroenterology, and can be used to predict the risk of recurrent ulcer bleeding. The shock index (SI), the number of erythrocytes, total protein, urea, localization of the ulcer and the type of hemostasis according to Forrest are determined. Each sign is evaluated in points. SI 1.0 or more is scored as 1 point. The number of erythrocytes less than 3.0*10¹² is estimated as 1 point; a total protein of 58 g/l or less is scored as 4 points; urea more than 8 mmol/l is estimated as 4 points. The localization of the ulcer along the lesser curvature of the stomach is estimated as 2 points. Localization on the back wall of the duodenal bulb - as 3 points. The condition of the bottom of the Forrest 2A ulcer is estimated as 2 points. The condition of the bottom of the ulcer Forrest 2C or 3 - as minus 3 points. Carry out the summation of points, while additionally determine the number of platelets and activated partial thromboplastin time (APTT). The number of platelets less than 150*109 is estimated as 2 points; APTT 40 seconds or more is estimated as 2 points. After that, with a sum of 9 to 19 points, a high risk of recurrent bleeding is predicted. With a sum of -3 to 8 points, a low risk of recurrent bleeding is predicted.

EFFECT: method provides the possibility of improving the accuracy of the forecast by taking into account the factors of the hemostasis system.
