Abstract (sommario):
Introduction Pancreatic trauma is notably less frequent than injuries affecting other solid organs, such as the liver or spleen. Despite their infrequency, pancreatic injuries can pose significant risks, with mortality rates ranging from 5 to 30% and morbidity rates reaching 50%. Managing such injuries remains contentious because of the anatomical complexity, lesion extent, and close proximity to neighboring organs. Methods Our study aimed to delineate the clinical and biological characteristics of pancreatic trauma and specify diagnostic and therapeutic modalities. This study was conducted retrospectively from 2010 to 2021 at Mahmoud El Matri Hospital’s General Surgery Department in Ariana, TUNISIA, and included five cases of blunt and open pancreatic trauma. Results Although rare, pancreatic injuries can lead to serious consequences, prompting the development of a diverse array of therapeutic options. Pancreatic trauma presents a complex clinical challenge, necessitating a comprehensive approach that considers various factors, such as injury severity, anatomical location, and patient condition. Advanced imaging techniques, including computed tomography (CT) scanning, Wirsung-MRI, and ERCP, aid in the accurate diagnosis and assessment of canal involvement. Conservative management was considered for cases with limited canal rupture, whereas endoscopic treatments showed promise for hemodynamically stable cases. Surgical interventions, such as duodenopancreatectomy, are reserved for exceptional cases with severe injuries. Conclusion Pancreatic trauma requires a comprehensive approach that considers factors such as injury severity, anatomical location, and patient condition. Ongoing research and collaboration are vital for refining pancreatic trauma management and proposing guidelines for facilitating decision-making.

Abstract (sommario):
Background: Diverticula are commonly observed in the duodenum. Duodenal diverticulum (DD) usually does not give symptoms throughout life and is diagnosed by coincidence. However, it may present with different symptoms in patients. Objective: This study aims to evaluate the prevalence of DD and juxtapapillary duodenal diverticulum (JDD) and its association with other possible pathologies and to determine its clinical impact by using Computed Tomography (CT). Methods: This retrospective observational study, which was taken consecutively between the years of 2013-2020, was evaluated in the Radiology Department. The total number of cases was 4850 (male-2440; female-2410). CT images were evaluated by two experienced radiologists at the workstation. DD and JDD prevalence and clinical findings in the hospital registry system were examined. Results: The age of the patients included in the study ranged from 17 to 92 years (mean age 46.94±16.42). In patients with DD (female-130; male-101), mean age was 62.24 ± 12.69 (21-92). The prevalence of DD was 4.76% (n=231). The prevalence of JDD was 4.02% (n=195) and increased with age (p<0.01). The average diameter of the JDD was measured as 23.29±8.22 (9.5-55.3) mm. A significant positive correlation was found between age and DD diameter (p=0.039). DDs were found most commonly 84.42% (n=195) in the second segment of the duodenum as JDD. In patients with JDD, the mean diameter of choledochus and wirsung canal were 6.7 ± 2.4 (3-15.3) mm and 0.31 ± 0.1 (0.1-6.5) mm respectively. The choledochal diameter was correlated with the JDD size (p = 0.004). Cholelithiasis (n=56), choledocholithiasis (n=20), cholecystitis (n=52), diverticulitis (n=15), duodenitis (n=37), pancreatitis (n=5) and hiatal hernia (n=60) with JDD were observed. Periampullary carcinoma was detected in one patient. Conclusion: Our study shows that cholelithiasis, choledocholithiasis, cholecystitis, diverticulitis, duodenitis, pancreatitis may be associated with JDD. Therefore, in contrast-enhanced abdominal CT scans taken for various reasons, investigation of the presence and characteristics of JDD and detection of pathologies that may be associated with JDD are important for patients to benefit from early diagnosis and treatment opportunities and to take precautions against possible complications.

Abstract (sommario):
Pancreatic traumas are rare, but particularly serious. Its management involves diagnostic and therapeutic difficulties. The mechanism of injury generally corresponds to crush injuries or direct trauma during public road accidents. They most often occur during polytrauma and the associated lesions then determine the prognosis and treatment methods. In stable patients, an imaging assessment using CT, magnetic resonance imaging, or even endoscopic retrograde pancreatography determines the type and topography of pancreatic lesions and specifies the damage of the main pancreatic duct, which accounts for the seriousness of the pancreatic trauma. The treatment of pancreatic trauma essentially depends on the integrity or not of the Wirsung duct. Treatment can be solely medical, but above all surgical and endoscopic when canal is damaged. There is report of 4 patient observations who were treated in the surgical emergency department at Annaba Algeria University Hospital during the year 2023 for isolated trauma of the pancreas. There are diagnostic circumstances and description of therapeutic conduct and the surgical consequences.

Abstract (sommario):
Cette thèse aborde la problématique de l'amélioration de la CholangioPancréatographie Rétrograde par voie Endoscopique (CPRE), en proposant une méthode avancée de segmentation et de reconstruction 3D des voies biliaires. Les techniques actuelles de la CPRE présentent des limites importantes, notamment en raison de la difficulté de la visualisation des voies biliaires à partir des images 2D, ce qui peut entraîner des erreurs de planification et des complications durant les interventions. La reconstruction 3D des voies biliaires, à partir des images de cholangio-IRM, apparaît comme une solution prometteuse pour surmonter ces difficultés. La thèse propose une nouvelle approche de segmentation automatique BDU-Net, à base du réseau U-Net, spécifiquement adaptée aux caractéristiques des images de cholangio-IRM. Les performances du BDU-Net ont été comparées avec celles de réseaux de segmentation de références, tels que V-Net et U-Net++, en utilisant des métriques quantitatives comme le score de Dice et la distance de Hausdorff, ainsi qu'une évaluation qualitative réalisée par des experts. Les résultats montrent une amélioration de la précision des reconstructions 3D grâce à BDU-Net. Cette thèse explore également l'impact des différentes méthodes de prétraitement des images de cholangio-IRM, incluant l'utilisation du recadrage dynamique, pour améliorer la qualité de segmentation. Ce prétraitement permet de mieux visualiser les structures biliaires, et d'améliorer la reconstruction 3D des voies biliaires, particulièrement dans les cas complexes. En plus des contributions en segmentation, cette thèse propose un plugin, nommé CPRE Pro, développé pour la plateforme 3DSlicer. Cet outil permet d'intégrer les reconstructions 3D dans le workflow clinique, facilitant la planification de la CPRE. Grâce à une interface intuitive, les cliniciens peuvent interagir avec les images de cholangio-IRM, effectuer des segmentations automatiques et visualiser l'anatomie biliaire en 3D
This thesis addresses the challenge of improving Endoscopic Retrograde Cholangiopancreatography (ERCP) by proposing an advanced method for 3D reconstruction of bile ducts. Current ERCP techniques face significant limitations, mainly due to the difficulty of visualizing bile ducts using 2D images, which can lead to planning errors and complications during interventions. The use of 3D reconstruction of bile ducts from MR cholangiography (MRCP) images presents a promising solution to overcome these challenges. The thesis introduces a novel approach for automatic segmentation called BDU-Net, based on the U-Net architecture and specifically tailored to MRCP images. The performance of BDU-Net was compared with other reference segmentation models, such as V-Net and U-Net++, using quantitative metrics like the Dice score and Hausdorff distance, as well as a qualitative assessment by experts. The results show a significant improvement in the accuracy of 3D reconstructions with BDU-Net. Additionally, the thesis explores the impact of various preprocessing methods for MRCP images, including dynamic cropping, to enhance the segmentation quality. This preprocessing step improves the visualization of bile duct structures and enhances 3D reconstruction, especially in complex cases. Beyond segmentation contributions, the thesis also presents a plugin called CPRE Pro, developed for the 3DSlicer platform. This tool integrates 3D reconstructions into the clinical workflow, facilitating ERCP planning. With an intuitive interface, clinicians can interact with MRCP images, perform automatic segmentations, and visualize bile duct anatomy in 3D, thus improving clinical decision-making and intervention planning
