New data on the surgical anatomy of the bile and pancreatic ducts
The anatomy of the bile and pancreatic ducts was studied in 140 corpses using anatomical dissection (100), a corrosion technique (20), and X-ray (20). The length of the bile duct was 67.15 ± 10.58 mm, and the length of its mouth — the large duodenal nipple — 18.00 ± 2.26 mm. The length of the large duodenal nipple refers to the length of the preduodenal part as 1: 3. The diameter of the bile duct was on average 7.64 ± 1.09 mm, and the diameter of its mouth was 3.79 ± 0.68 mm. The ratio of the diameter of the bile duct to the diameter of its mouth is normally in the range of 1.18-3.50. These coefficients must be taken into account when diagnosing stenosis of the large duodenal papilla and during operations on it.
