ABSTRACT
Introduction: Without the knowledge of the normal pattern of the duct system and its variations, a radiologistcan’t interpret an Endoscopic Retrograde Cholangiopancreatography (ERCP) picture. So it becomes important tostudy the anatomy of pancreatic ducts, their relation to each other, to common bile duct and to duodenum in theavailable human cadavers. The present paper is about the study of distance between minor and major duodenalpapilla from pylorus which was carried out on 96 cadaveric specimens of human duodeno-pancreas. To visualiseand to see distance between minor and major duodenal papillae is necessary for the endoscopist who aims toperform the dilation, stenting, or papillotomy of the minor papilla.Materials and Methods: The study was conducted in 96 (64 male and 32 female) cadavers. Major and minorduodenal papillae were visualized through eosin dye installation in both common bile duct and the accessorypancreatic duct. The measurement of distance between the duodenal papillae and to pylorus was done in cm.Results: In the present work, the mean ± SD of the Distance between pylorus to MAP is 8.05 ± 1.71 cm, pylorus toMIP is 6.19 ± 1.49 cm, the major to minor duodenal papilla was on an average 2.02 ± 0.40 cm, these distanceswere more in males as compared to females. But the size of Orifice of MAP in specimens is 7.25 ± 1.25 mm morein females as compared to males.Conclusion: The length of the duct shows sexual dimorphism; the length being more in males than females.
ABSTRACT
The accessory pancreatic duct is the smaller and less constant pancreatic duct in comparison with the mainpancreatic duct. We investigated the patency of the accessory pancreatic duct and its role in pancreaticpathophysiology. The present study was carried out in the department of Anatomy and forensic medicine, ACSRGovt. medical college, Nellore, Andhra Pradesh, India and in the department of Anatomy, RIMS, Ongole, AndhraPradesh, India. With 96 human cadavers (64 males and 32 females) with 30 to 80 years age group have beenstudied after obtained of ethical committee permission. The dissection method was followed to obtain specimenof pancreas along with C-loop of duodenum, papillae were identified ad dye was injected into APD to see itspatency at MIP. 93.75% specimens present MIP. The prevalence of patency of APD at MIP in population understudy was 38.89%; this is more in males was 43.33%, when compared to the females was 30% but this differencewas not significant statistically. It observed that out of 35 patent APD cases, 33 cases had inter papillarydistance either 2cm or more than 2cm. I t indicates 94.29% of patent APD cases had inter-papillary distancee”2cm. So there is strong relationship between APD patency and inter papillary distance in population understudy. The means inter-papillary distance in patent APD cases was 2.29 ± 0.2cm and non-patent APD cases was1.85 ± 0.25 cm. This difference was statistically significant.
