Morphology of the Hepatopancreatic Ampulla by the Injection-Radioscopy Method: Anatomical Study and Clinical Applications About 30 Cases

Objective: the purpose of our work was to study the configuration of the hepato-pancreatic junction and to review the literature. Material and method: It was a fundamental observational study for descriptive purposes. It was about 30 pieces of fresh pancreas taken from anatomical subjects during forensic autopsy. The average age was 39.43 years. The cephalo-isthmic configuration of the pancreatic ducts was studied by the injection-radioscopy method. The mode of constitution of the hepatopancreatic (AHP) was evaluated based on the Flati classification [1]. The parameters studied were morphological and morphometric. Results: in 18 cases (60%), there was a "Ya" type with an average length of 5.4mm of the AHP and an average diameter of 1.6mm. In 1 case (3.3%), we observed a "Yb" type with a length of 12mm of the AHP and a diameter of 1.9mm. In 2 cases (6.7%), the AHP had the shape of a "V" with an average length of 0.95mm of the AHP and an average diameter of 0.7mm. In 8 cases (26.7%), the AHP had the shape of a "U". In 1 case (3.3%), the AHP had the form of an "II". Conclusion: The anatomical study of the AHP in the population is interesting in the sense that it makes it possible to identify or estimate the groups at risk regarding the occurrence of certain pathologies of the bilio-pancreatic pathways.
