[Importance of urgent histological investigation in surgical treatment of biliopancreatoduodenal zone carcinoma].

Urgent intraoperative investigation allows a surgeon, depending on the morphological conclusion, to conduct individual surgical intervention in the form of anastomosis with penetration into the tissue of the pancreas. The method decreases the rate of surgical complications, improves immediate results of patient treatment and reduces postoperative lethality. This proves the importance of morphology in the surgical treatment of tumours in the zone concerned.
