Prevalence Of Patency Of Accessory Pancreatic Duct At Minor Papilla In South Indian Population: A Cadaveric Study

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.

Cadaveric Study of The Anatomical Variations of The Accessory Pancreatic Duct.

Background: The accessory pancreatic duct enters the duodenum at the minor duodenal papilla, developmentally draining the dorsal pancreatic bud; however, it is smaller and less constant than the main pancreatic duct and undergoes varying degrees of atrophy at the duodenal end. Objective: The objective of this study was to see the variations in course, opening and communication pattern of the accessory pancreatic duct in different age-groups in a Bangladeshi population. Methods: This crosssectional, descriptive study was done was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from August 2005 to December 2006, based on collection and dissection of 75 postmortem male human pancreas. The collected samples were divided into seven age groups: 10-19 years, 20-29 years,30-39 years, 40-49 years, 50-59 years),60-69 years and(eˆ70 years. However, 65 samples were taken for final observation. Results: The accessory pancreatic duct was found in 27.69% specimens. Straight course was found in 50% specimen, while spindle course in 27.78% and cudgel course in 22.22% specimens were observed. In only 4 (6.15%) specimens, the accessory pancreatic duct communicates with the common bile duct, while in 11 (16.93%) specimens, the accessory pancreatic duct communicates with the main pancreatic duct. 12 (66.67%) accessory pancreatic ducts opened into the minor duodenal papilla, while 5 (27.78%) into the major duodenal papilla and 1 (5.55%) into the 3rd duodenal papilla. Conclusion: Several variations were observed in accessory pancreatic duct pattern in terms of their course, opening and communications. However, no significant differences were evident in any parameter among the age groups. Here, females were excluded due to less availability of the female cadaveric pancreas during study period.

A cadaveric study of distance between the terminations of the hepato- pancreatic and accessory pancreatic ducts in the duodenal mucosa.

Objective: The present paper is about the study of distance between minor and major duodenal papillae which was carried out on 30 cadaveric specimens of human duodeno-pancreas. With introduction of ERCP, the pattern of pancreatic ductal system visualization has attained popularity. Without the knowledge of the normal pattern of the duct system and its variations, a radiologist can’t interpret an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) picture. So it becomes important to study the anatomy of pancreatic ducts, their relation to each other, to common bile duct and to duodenum in the available human cadavers. To visualise and to see distance between minor and major duodenal papillae is necessary for the endoscopist who aims to perform the dilation, stenting, or papillotomy of the minor papilla. ERCP is proved to be “first line” therapeutic tool in the management of surgical, medical and pathological disorders involving the biliary tree and pancreatic duct. Methods: The study was conducted in thirty (20 male and 10 female) cadavers. Major and minor duodenal papillae were visualized through eosin dye installation in both common bile duct and the accessory pancreatic duct. The measurement of distance between the duodenal papillae was done in cm. Results: In the present work, the distance measured between the major and minor duodenal papilla was on an average 1.93+0.61 cm. in females and in males it was 2.05+0.31 cm. Conclusion: The length of the duct shows sexual dimorphism; the length being more in males than females.

A case of bleeding from the accessory pancreatic duct associated with aneurysmal dilatation of pancreaticoduodenal artery / 대한내과학회지

Gastrointestinal bleeding through the pancreatic duct especially from the minor papilla through the accessory duct is a very rare event. It has rarely been demonstrated to be associated with pancreatic pseudocyst, arteriovenous malformation, pancreas divisum, and duodenal duplication cyst. We have experienced a 51-year old man having sudden onset melena. He had been recovered from a recent myocardial infarction and was on the aspirin treatment. Upper gastrointestinal endoscopic examination revealed bleeding through minor papilla from the accessory duct but no bleeding was observed through the ampulla of Vater. Angiogram demonstrated two sites of aneurysmal dilatation of pancreaticoduodenal artery and these were obliterated by selective embolization. Thereafter the bleeding was controlled and patient was recovered.

A Case of Intraductal Papillary Mucinous Tumor Arising from the Accessory Pancreatic Duct / 대한소화기내시경학회지

Mucin-producing tumors of the pancreas were first reported by Ohhashi and Takagi in 1980. Since then, many cases of intraductal papillary mucinous tumor (IPMT) of the pancreas, which is almost homonymous to mucin-producing tumors of the pancreas, have been reported. IPMTs are generally regarded as tumors with a favorable prognosis. Some IPMTs have invasiveness and this is always associated with a poor prognosis. Most IPMTs arise from the main pancreatic duct and IPMTs arising from the accessory pancreatic duct are relatively rare. Only 6 cases have been reported in the literature so far. Our patient was a 43-year old man who was admitted to the hospital due to recurrent pancreatitis. An endoscopic retrograde pancreatography revealed a patulous minor papilla orifice extruding mucin and a cystic lesion in a branch of the accessory duct. A pancreaticoduodenectomy was performed and a pathologic examination of the resected specimen showed intraductal papaillary mucinous neoplasm, low grade malignancy, in the accessory pancreatic duct and its branch. We herein report this interesting case with a review of the literature.
