METHOD FOR SETTING INTRASURGICAL LAPAROSCOPIC ULTRASONIC DIAGNOSIS OF LARGE INTESTINE CANCER GENERALIZATION Russian patent published in 2004 - IPC

FIELD: medicine. SUBSTANCE: method involves diagnosing metastasis at scanning frequency from 5 to 7.5 MHz. Sterile multi-frequency convex laparoscopic scanning transducer is introduced into abdominal cavity via single-use trocar set into the trocar opening produced for carrying out surgical intervention. Diagnosis of metastasis into the liver and remote and regional lymph nodes is set and their shape, size and structure is determined. Ultrasonic large intestine tumor revision is carried out in a series of longitudinal and oblique scanning cross-sections with tumor length, its structure, intestine wall infiltration depth and tumor process propagation into surrounding tissues and adjacent organs being determined. Ultrasonic transducer introduction place is selected depending on surgical intervention type studied organ localization. The tumor being localized in the right half of colon, transducer is introduced into trocar above the umbilicus when liver is investigated, it is introduced into trocar in superior left iliac area, when diagnosing para-aortic zone and iliac area. The tumor being localized in the left of colon, transducer is introduced into trocar above the umbilicus or into trocar in superior right iliac area when liver is investigated, the transducer is introduced into superior right iliac area when diagnosing para-aortic zone and iliac area. The tumor being localized in the rectum, the transducer is introduced into trocar in superior right iliac area when liver is investigated, it is introduced into trocar in inferior or superior when diagnosing para-aortic zone. The transducer is introduced into inferior right or left iliac area when diagnosing iliac areas. The transducer is introduced into inferior right iliac area when carrying out tumor revision. EFFECT: high accuracy of intrasurgical diagnosis. 4 cl
