METHOD FOR INTRAOPERATIVE ASSESSMENT OF POSSIBILITY OF ATRAUMATIC TRANSRECTAL REMOVAL OF SURGICAL PREPARATION IN LAPAROSCOPIC RESECTIONS OF LEFT COLON FOR CANCER Russian patent published in 2024 - IPC A61B17/94 A61B5/107 A61M29/00 

FIELD: medicine.

SUBSTANCE: invention relates to colorectal surgery, oncology, and can be used in surgical treatment of left colon cancer. Intracorporeal measurement of the circumference of the future preparation is carried out in the most voluminous place with a centimeter tape. Anal dilator is inserted into the anal canal with a force of not more than 20 N. Pressure in the anal canal is measured and, while maintaining a constant pressure parameter for 30 seconds, circumference of anal canal is measured by circular marking of anal dilator. Obtained value is compared with the circumference of the removed preparation, and if the circumference of the anal canal is greater than or equal to the circumference of the removed preparation, the possibility of atraumatic transrectal removal of the surgical preparation is determined.

EFFECT: method makes it possible to perform safe radical and low-traumatic operation in patients with diagnosed left colon cancer based on intraoperative measurements, reducing the probability of anal sphincter injury and damage to the removed surgical preparation, reduces the rate of postoperative complications, reduces time of patient’s activation after surgery and time of staying in hospital.
