Where to incise and/or divide the cystic duct.

The study concern was to establish the position of cystic duct incision/division in circumstances of laparoscopic cholecystectomy. Seventy consecutive human cadavers were dissected. Corrosion casting (50) and post-mortem cholangiography (20) were employed. Cystic duct length was 34.6 mm, and in 88.6% cases its length was 1-5 cm. Mean cystic duct diameters next to the gallbladder neck, within the valve and 5 mm proximal to the junction with the common hepatic duct were 1.95, 0.42 and 1.85 mm, respectively. Lateral cysto-hepatic junction was identified in 78.6%, spiral in 10% and parallel in 10%. In 90% cases the cysto-hepatic junction is within 4 cm of the hepatic duct junction. One case (1.43%) of cystic duct entering the right hepatic duct was identified. The valve of Heisteri consisted of three spiral turns in 73% of the cases with a range from 0 to 5. In 3/70 specimens the spiral valve did not exist.
