Clinical and paraclinical characteristics in pediatric patients with acute recurrent and chronic pancreatitis: a cohort in Mexico / Características clínicas y paraclínicas en pacientes pediátricos con pancreatitis aguda recurrente y crónica: una cohorte en México

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.

The value and significance of gene sequencing in the diagnosis of pediatric pancreatitis / 中国小儿急救医学

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.

Pancreatitis biliar recurrente asociada a vesícula biliar de localización anómala y comunicación interauricular / Recurrent biliary pancreatitis associated with analyzed biliar localization vesicle And interauricular communication

Mujer de 32 años que ingresa al servicio de medicina con cuadro clínico de pancreatitis biliar recurrente y colelitiasis sintomática. La ecografia abdominal y la Colangioresonancia mostró vesícula biliar en posición no habitual (posterior) y anomalía del árbol biliar. Incidentalmente se evidencia la presencia de una comunicación interauricular asociada a signos compatibles con hipertensión pulmonar. No hemos encontrado en la literatura asociación entre la presencia de esta anormalidad de la vesícula biliar y la presencia de comunicación auricular u otras cardiopatías congénitas.

A 32-year-old woman admitted to the medical service with a clinical picture of recurrent biliary pancreatitis and symptomatic cholelithiasis. Abdominal ultrasound and cholangioresonance showed a gallbladder in an unusual position (posterior) and an anomaly of the biliary tree. Incidentally, the presence of an atrial septal defect associated with signs compatible with pulmonary hypertension is evident. We have not found in the literature an association between the presence of this gallbladder abnormality and the presence of atrial or other congenital heart disease.

Intra-ampullary Adenocarcinoma Presenting as Recurrent Pancreatitis / 대한췌담도학회지

Advances in imaging modalities have provided useful information in diagnosing ampullary lesions such as adenoma and adenocarcinoma. Endoscopic retrograde cholangiopancreaticography (ERCP) have a role in the diagnosis of unexposed intra-ampullarylesion. We report an interesting case of adenocarinoma of the ampulla of Vater presenting as idiopathic recurrent pancreatitis. A 56 years old woman was referred due to idiopathic recurrent pancreatitis for 2 years. She presented abdominal pain and upper abdominal tenderness. Magnetic resonance cholangiopancreaticography (MRCP) revealed minimal bile and pancreatic ductal dilatation without obstruction. Subsequent ERCP revealed a small polypoid lesion which was exposed after endoscopic sphincterotomy. Endoscopic biopsy showed papillary adenoma with low grade dysplasia. Additional endoscopic papillectomy was performed. Endoscopic biopsy done 3 months later showed papillary adenoma with high grade dysplasia. Pylorus preserving pancreatoduodenectomy was done and final pathology was well differentiated adenocarcinoma. The patient was recovered well but received adjuvant chemotherapy due to metastatic lymph nodes.

A Case of Branch Duct Intraductal Papillary Mucinous Neoplasm Mimicking Pseudocysts Complicated by Recurrent Pancreatitis / 대한췌담도학회지

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.

Pancreatitis recurrente por disquinesia hipertónica del esfínter de oddi: tratamiento endoscópico y seguimiento a largo plazo en un caso clínico / Recurrent pancreatitis caused by oddi sphincter’s hypertonic dyskinesia: case report of endoscopic treatment and long-term follow-up

It is frequently difficult to determine the exact cause of recurrent acute pancreatitis (RAP), which can be life threatening in several cases. Not detected biliary microlithiasis is the most frequent etiology, buthypertonic dyskinesis of Oddi’s sphincter also can cause RAP. Non-invasive diagnosis of this functional disorder is difficult, endoscopic manometry of Oddi’s sphincter allows measuring pressure in the choledochus,in the pancreatic duct and specifically in the sphincter region. Once hypertonic dyskinesis is demonstrated, the treatment option is the partial or total ablation of the sphincter, via endoscopic or surgical methods. This intervention results in an improvement or complete resolution in about 70 percent of the patients, preventing new bouts of acute pancreatitis and eventual progression to chronic disease. In this paper, we describe the history of one of our patients, who consulted more than ten years after cholecystectomy for recurrent abdominal pain and presented three episodes of acute pancreatitis. Endoscopic manometry of Oddi’s sphincter was performed in 1997, with the detection of very high pressure in biliary and pancreatic segments of the sphincter, demonstrating hypertonic dyskinesis involving both segments. A dual endoscopic sphincterotomy was performed, followed by marked reduction in the pressure of biliopancreatic ducts and Oddi’s sphincter and in abolition of choledocho-duodenal and pancreatic-duodenal gradient. She was asymptomatic till 2002, later on, she required endoscopic pneumatic dilatation of the sphincterotomy. She had no more acute pancreatitis episodes and CT scan in 2014 showed a normal pancreas.

Con frecuencia resulta difícil determinar la etiología de la pancreatitis aguda recurrente (PAR), que puede amenazar hasta la vida del paciente. Aparte de la patología litiásica biliar no diagnosticada, la disquinesia hipertónica del esfínter de Oddi (EO) causa con cierta frecuencia PAR. Su diagnóstico no invasivo es difícil, la manometría del esfínter de Oddi permite medir los valores de la presión en la vía biliar, en el conducto pancreático y en la región del esfínter. Una vez que la disquinesia hipertónica se demuestra, su tratamiento es la ablación parcial o total del esfínter, con método endoscópico o quirúrgico, con resolución del cuadro clínico en aproximadamente 70 por ciento de los pacientes, logrando evitar los nuevos brotes de pancreatitis aguda (PA) y la eventual progresión hacia pancreatitis crónica. En este trabajo describimos la historia de una paciente colecistectomizada, quien después de varios años de dolor abdominal recurrente, presentó tres brotes de PA. Manometría de EO fue realizada en 1997, detectando presiones muy elevadas, comprobando disquinesia hipertónica de los segmentos biliar y pancreático del esfínter. Se realizó esfinterotomía endoscópica doble, seguida por gran disminución de los valores de presión, abolición del gradiente colédoco-duodenal y pancreático-duodenal. Estuvo asintomática hasta el 2002, y posteriormente requirió dilatación neumática de los orificios de esfinterotomías. No ha tenido más recaídas de pancreatitis, la tomografía computada de control en noviembre de 2014 mostró un páncreas normal.

Evaluation of previous abdominal pain episodes in women with biliary pancreatitis: possible higher incidence of recurrent attacks.

Background and aim: Recurrent biliary pancreatitis is described as episodes of new abdominal pain after diagnosis of pancreatitis. Few studies have analyzed the abdominal pain before the diagnosis of acute pancreatitis. Our study aimed to analyze factors associated with previous abdominal pain episodes in patients with biliary pancreatitis, and elucidate its possible pancreatic origin. Methods: Data from direct interrogation and medical records was analyzed from 48 hospitalized female patients with diagnosis of acute biliary pancreatitis. Results: Mean age of our patients was 31.6 years (SD+13.9). Forty one (85.4%) patients gave history of at least one previous abdominal pain episode. During the episode 37 (90.2%) patients received H2 receptor antagonist or proton pump inhibitors as treatment; 26 (63.4%) had epigastric pain; 23(56.1%) gave association with cholecystokinetic food; 21 (51.2%) complained of nausea and/or vomiting; 23 (56.1%) had jaundice, acholia and/or dark urine; and 20 (48.9%) patients had microlithiasis and/or biliary sludge. Conclusions: Previous abdominal pain episodes had similar characteristics to a pancreatic episode in a high percentage of our patients. These characteristics suggest that these episodes are often undiagnosed pancreatic attacks.

Disfunción del esfínter de Oddi y pancreatitis idiopática / Sphincter of Oddi dysfunction (SOD) and idiopatic pancreatitis

The sphincter of Oddi dysfunction is a little known entity that typically occurs in post-cholecystectomy patients with abdominal pain with biliary or pancreatic characteristics. It represents an important cause of idiopathic recurrent acute pancreatitis. Most of the patients referred for sphincter of Oddi dysfunction study have another disease which explain the symptoms, so a careful history and appropriate physical examination often can identify the true source of the pain. The most used grading score is the Milwaukee classification, based on clinical, laboratory, imaging and cholangiographic findings. In the last decade, new and more applicable criteria have been developed, such as Rome III criteria, which do not require functional tests considered complex and not available in non-specialized centers. The sphincter of Oddimanometry is considered the gold standard for the diagnosis of this entity, allowing for the determination of which patients will benefit from endoscopic therapy (sphincterotomy). There are some noninvasive diagnostic tests that have failed to show strong correlation to displace the sphincter of Oddi. The treatment of this condition is mainly based on endoscopic sphincterotomy, with variable success rates depending on the type of dysfunction. This article presents a review of the most important aspects related to the sphincter of Oddi and its relationship with idiopathic recurrent pancreatitis.

La disfunción del esfínter de Oddi es una entidad poco conocida, que típicamente se presenta en pacientes post-colecistectomía con dolor abdominal de tipo “biliar” o “pancreático”. Representa unaimportante causa de pancreatitis aguda recurrente idiopática. La mayoría de los pacientes derivados para estudio de disfunción del esfínter de Oddi corresponden a otra causa o enfermedad que explica los síntomas, por lo que una cuidadosa historia clínica y un adecuado examen físico, a menudo permiten identificar el verdadero origen del cuadro doloroso. La clasificación más utilizada es la de Milwaukee basada en parámetros clínicos, de laboratorio, imagenológicos y colangiográficos. En la última década, se han elaborado criterios de mayor aplicabilidad clínica como los criterios de Roma III, que no requieren de test funcionales considerados complejos y poco disponibles en centros no especializados. La manometría del esfínter de Oddi es considerado el gold standard en el diagnóstico de esta entidad, permitiendo además, establecer quiénes se beneficiarán con la terapia endoscópica (esfinterotomía). Se han desarrollado una serie de otros métodos diagnósticos no invasivos, que no han logrado demostrar una correlación suficientemente sólida para desplazar a la manometría. El tratamiento de esta condición se basa principalmente en la esfinterotomía endoscópica, con una tasa de éxito variable dependiendo del tipo de disfunción. En el presente artículo se revisarán los aspectos más importantes relacionados con la disfunción del esfínter de Oddi y su relación con pancreatitis recurrente idiopática.

A case of pancreatic intraepithelial neoplasm (PanIN-III) manifesting as recurrent pancreatitis / 대한내과학회지

Acute recurrent pancreatitis has a variety of etiologies. We experienced a case of a tumor-forming pancreatitis in a 49 year old Korean woman who also had pancreatic intraepithelial neoplasm III (PanIN-III), and this manifested just like recurrent pancreatitis. She had a history of recurrent pancreatitis. She was found to have an early stage of pancreatic cancer via computed tomography and magnetic resonance cholangiopancreatography. EUS guided fine needle aspiration (FNA) showed only many acinar cells of the pancreas. But due to the possibility of her having pancreatic carcinoma, she underwent distal pancreatectomy and splenectomy with lymph node dissection. Pathologically, the tumor of the pancreatic body showed secondary changes with focal fibrosis from the localized chronic pancreatitis. PanIN-III was observed in the pancreatic duct within the tumor, and there were no cancerous findings in the 13 dissected lymph nodes.

A Case of Juxtapapillary Duodenal Duplication Cyst Manifested by Recurrent Pancreatitis / 대한소화기내시경학회지

Duodenal duplication cyst is an uncommon congenital anomaly that is usually encountered during infancy or in early childhood. The clinical manifestation is that of duodenal obstruction or, less commonly, obstructive jaundice, acute pancreatitis, or gastrointestinal bleeding. Here, we report a case of duodenal duplication cyst on the juxtapapillary region in a 19-year-old woman with an unusual clinical manifestation of recurrent pancreatitis and peculiar endoscopic finding of the cyst.

A Case of Acute Recurrent Pancreatitis Whose Etiology was Diagnosed by Endoscopic Ultrasonography / 대한소화기내시경학회지

Acute recurrent pancreatitis results most commonly from gallstone disease. Although transabdominal ultrasound is a common procedure for evaluating biliary tract, it may not be effective in minilithiasis. We here report a case of acute recurrent pancreatitis, in which endoscopic ultrasonography revealed minilithiasis in the gallbladder with a review of the literature. A 57-year-old woman had suffered from idiopathic recurrent pancreatitis four times for the past 4 months. While transabdominal ultrasonography and abdominal computerized tomography revealed no evidence of bliary stones, but EUS exhibited minilithiasis in the gallbladder. After laparoscopic cholecystectomy, no further events of pancreatitis happened.

Primary Malignant Lymphoma of the Ampulla of Vater / 대한소화기내시경학회지

The vast majority of ampullary tumors are epithelial in nature and are either adenoma or adenocarcinoma. Rarely lymphoma or mucinous and squamous elements may be found. Primary lymphoma of pancreaticobiliary region are exceedingly rare, and mostly nodal. Recently, we have experienced a 29-year-old woman with primary malignant lymphoma of the ampulla of Vater with recurrent acute pancreatitis and jaundice. On duodenoscopy, bulging ampulla with normal overlying duodenal mucosa was observed. Endoscopic sphincterotomy was done and tumor inside the ampulla was exposed. ERCP showed high grade biliary and pancreatic ductal strictures extending from the papillary orifice, with upstream ductal dilatation, respectively. With endoscopic biopsy alone, the tumor was confirmed as B-cell lymphoma histologically.
