Normal pancreatic duct morphology in a north Indian population.

Ninety three normal pancreatograms from a North Indian population were studied. The pancreatic duct (PD) was L-shaped in 47%, oblique in 5% and sigmoid in 11%. The mean length (SD) of PD was 18.2 (3.0) cm, being longer in males but not varying with age. The mean maximum diameters of PD in head, body and tail were 3.7 (0.8), 2.7 (0.6) and 1.7 (0.4) mm respectively. These did not vary with sex. The PD diameters showed a statistically significant increase with age but this variation does not appear to be of much practical importance.
