ABSTRACT
Abstract Background: Acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) are infrequent clinical entities in pediatric patients, as less than 8% of the literature mentions this population. This study aimed to describe the clinical and paraclinical profile, and the etiology related to patients with ARP and CP attended at a tertiary-level healthcare institute in Mexico. Methods: We conducted a retrospective study from medical records of patients with ARP and CP attended between 2010 and 2020, analyzing the clinical characteristics, imaging studies, and the etiology associated with each patient. Results: We analyzed 25 patients: 17 were diagnosed with ARP, and eight with CP. The main etiology identified was an anatomical alteration of the pancreatic duct (32%); pancreas divisum was the most prevalent condition. In 48% of the population, the etiology was not identified. The group with CP was higher in frequency for calcifications and dilation of the pancreatic duct (p < 0.005) compared to the ARP group. Conclusions: The main etiology for ARP and CP was an anatomical alteration of the pancreatic duct; however, in almost half of the cases, no established cause was identified. Although comparing our results with those offered by large cohorts such as the INSPPIRE group can be complex, we found relevant similarities. Currently, the data obtained from this first descriptive study are the foundation for future research in the field of Mexican pediatric pancreatology.
Resumen Introducción: La pancreatitis aguda recurrente (PAR) y crónica (PC) son entidades poco frecuentes en la edad pediátrica; sin embargo, menos del 8% de la literatura hace referencia a esta población. El objetivo de este estudio fue describir el perfil clínico, paraclínico y etiologías vinculadas en los pacientes con PAR y PC atendidos en una institución de tercer nivel de atención en México. Métodos: Se realizó un estudio retrospectivo de los expedientes de los pacientes con PAR y PC atendidos entre 2010 a 2020, analizando las características clínicas, estudios de imagen y etiologías asociadas en cada uno de los pacientes. Resultados: Se analizaron 25 pacientes, 17 con diagnóstico de PAR y ocho con PC. La principal etiología identificada correspondió a las alteraciones anatómicas del conducto pancreático (32%); el páncreas divisum fue la entidad más prevalente. En el 48% de la población no se pudo identificar una etiología. El grupo con PC presentó mayor frecuencia de calcificaciones y dilatación ductal pancreática (p < 0.005) en comparación al grupo de PAR. Conclusiones: La principal etiología de PAR y PC identificada en nuestro estudio corresponde a las alteraciones anatómicas del conducto pancreático; sin embargo, en casi la mitad de los casos, no se tiene una causa establecida. Aunque es complicado comparar nuestros resultados con los ofrecidos por las grandes cohortes del grupo INSPPIRE, sí encontramos similitudes relevantes. Los datos obtenidos en este primer estudio descriptivo son la base para futuras investigaciones en el ámbito de la pancreatología pediátrica mexicana.
ABSTRACT
Genetics has become one of the most important factors in the etiology of pediatric pancreatitis with advances in technology and clinical studies.Variations in these genes may increase the risk of acute recurrent and chronic pancreatitis in children, accelerate progression to endocrine and exocrine pancreatic insufficiency, and increase the risk of pancreatic cancer in adulthood.This review summarized the clinical research on the relationship between gene variations and pancreatitis, elaborated on the mechanisms, risks, and clinical phenotypes of pancreatitis caused by different gene variations, and analyzed the significance of related gene sequencing in children with pancreatitis.It aims to help pediatricians know the indications of gene sequencing in pediatric pancreatitis and do much better in relevant diagnosis, prognosis evaluation, and genetic counseling.
ABSTRACT
Pancreatitis is one of the common diseases of digestive system in children, especially acute recurrent pancreatitis(ARP)and chronic pancreatitis(CP)which can seriously affect the life quality of children and increase the burden of the family.With the application of gene detection technology in recent years, the awareness of etiology and risk factors on ARP and CP is inhenced.And also the application of endoscopic retrograde cholangiopancreatography(ERCP)offers hope for patients′ treatment.Therefore, this article will review the risk factors, clinical manifestation, auxiliary examination, diagnosis and treatment of ARP and CP to make patients obtain better assessment and reasonable treatment.
ABSTRACT
Branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) are characterized by cystic dilation of secondary ducts clearly communicating with a normal-sized main pancreatic duct and seem to have a less aggressive clinical course than those arising from the main duct. BD-IPMNs are related to pancreatitis but the causal relationship is unclear. We report a case of a 62-year-old woman initially thought to have pseudocysts complicated by idiopathic recurrent pancreatitis but was finally diagnosed with BD-IPMN leading to recurrent acute pancreatitis attacks. The patient had six episodes of acute pancreatitis over 5 years. An abdominal computed tomography scan revealed two cystic lesions of 2.0 and 1.5 cm in the pancreatic body, which appeared at the second episode of acute pancreatitis. Each pancreatitis episode improved with conservative treatment, but the cystic lesions increased in size to 2.5 and 3.5 cm during the late follow-up period. A distal pancreatectomy was performed under the diagnosis of recurrent pancreatitis caused by BD-IPMN. The pathological findings revealed BD-IPMN with moderate dysplasia. We herein present a case of BD-IPMN mimicking pancreatic pseudocysts with a review of the literature.
