Abstract

Introduction

Dilatation of the MPD is associated with number of significant pancreatic pathologies. To identify the dilated MPD, it is of great importance to study the demographic data of the normal size of the MPD in a given population.

 

Objective

To assess the diameter of MPD in normal subjects.

 

Methodology

Prospective descriptive study was carried out at Colombo South Teaching Hospital from March 2016 to May 2016. All CECT abdomen and pelvis examinations performed during this period with clinical, biochemical and radiological evidence of normal pancreas were included. CT measurements of the MPD diameter were obtained by two individuals independently on the subjects who underwent abdominal CECT scans (16 section MDCT, 1-5mm increments, and dual phase) and each measurement was obtained in venous phase images for three times and mean value was taken.

 

Results

There were 190 men and 132 women with age ranging from 20–88 years (mean 53.6). MPD was adequately visualized only in 72% (n=231) of subjects. The mean diameter of the MPD in the head, body and tail were 2.9, 2.2 and 1.6 mm respectively. There is no statistical significant difference observed in MPD diameter between two sexes and the two age groups of <40 and >40 years (p>0.05).

 

Conclusion

The diameter values of MPD in our study are comparable to that of foreign population groups. However there was no correlation between MPD diameter with the age or sex in the study which was different to the published data which showed higher proportion of MPD diameter with increasing age and female gender.
