BACKGROUND: First described 70 years ago, intraoperative cholangiography is an effective method of study of the biliary tract. There are several ways of its realization. AIM: To add a new technique of cholangiography in relation to the classical one using only two radiographs for static and dynamic interpretation. METHODS: Cholangiography is made with two X-rays, the first with overpressure and the second three minutes later, in emptying time. It was performed on 39 patients with gallstones undergoing cholecystectomy by laparotomy. The evaluation of the radiographs was based on a radiographic classification created by the authors, varying in degrees in the overpressure from 0 to 3 and emptying of 1 to 3. RESULTS: The complete or almost complete filling of the biliary tree was found in 66.7% of patients in the phase of overpressure. In the emptying phase, 59% of patients had 1/3 or less contrast on biliary tree. There was a need to add additional radiographs in 5% of patients after seven minutes, with complete emptying. CONCLUSION: The proposed technique proved feasible, simple, fast and effective.
