Manejo quirúrgico de pseudoquiste pancreático gigante: caso clínico / Surgical management of giant pancreatic pseudocyst: case report

Resumen Introducción: Los pseudoquistes pancreáticos (PQP) corresponden al 80% de las lesiones quísticas del páncreas. Se debe descartar un tumor quístico, que representan el 10% al 15% de los quistes del páncreas y 1% de los tumores malignos por lo que es fundamental el estudio y diagnóstico diferencial. El término pseudoquiste pancreático gigante se usa tradicionalmente cuando el tamaño es mayor de 10 cm. Hay pocos casos de PQP gigantes en la literatura nacional. Objetivo: Reportar caso clínico con PQP gigante, analizar el diagnóstico diferencial y las opciones terapéuticas. Materiales y Método: Paciente con distensión abdominal progresiva, pérdida de peso y anorexia, posepisodio de pancreatitis aguda. Tomografía computarizada abdominal y resonancia magnética confirman lesión quística gigante intraabdominal. El paciente fue tratado con una cistoyeyunostomía pancreática abierta en Y de Roux. El análisis del contenido aspirado durante la cirugía sugiere PQP. Para la discusión se revisa la literatura más relevante. Resultados: Excelente resultado clínico postoperatorio, el estudio histopatológico de la pared del quiste confirmó el diagnóstico de pseudoquiste pancreático. Al año de seguimiento, el paciente permanece asintomático. Discusión: El estudio preoperatorio es crucial para determinar el diagnóstico diferencial y descartar lesiones neoplásicas o parasitarias quísticas. Los PSQ gigantes reportados son poco frecuentes y su manejo quirúrgico dependerá fundamentalmente de su tamaño, de las relaciones anatómicas y de la experiencia del equipo tratante.

Introduction: Pancreatic pseudocysts (PQP) correspond to 80% of cystic lesions of the pancreas. A cystic tumor must be ruled out, which represents 10% to 15% of pancreatic cysts and 1% of malignant tumors, so the study and differential diagnosis is essential. The term giant pancreatic pseudocyst is traditionally used when the size is greater than 10 cm. There are few cases of giant PQP in the national literature. Objective: To report a clinical case with giant PQP, to analyze the differential diagnosis and therapeutic options. Materials and Method: Patient with progressive abdominal distension, weight loss and anorexia post episode of acute pancreatitis. Abdominal computed tomography and magnetic resonance imaging confirm a giant intra-abdominal cystic lesion. The patient was treated with an open Roux-en-Y pancreatic cysto-jejunostomy. Analysis of the content aspirated during surgery suggests PQP. The most relevant literature is reviewed for discussion. Results: Excellent postoperative clinical results, the histopathological study of the cyst wall, confirmed the diagnosis of pancreatic pseudocyst. At one year of follow-up, the patient remains asymptomatic. Discussion: The preoperative study is crucial to determine the differential diagnosis and rule out neoplastic or cystic parasitic lesions. Reported giant PSQs are rare and their surgical management will depend fundamentally on their size, anatomical relationships, and the experience of the treating team.

Efficacy and safety of endoscopic ultrasound-guided drainage of pancreatic pseudocysts using double-pigtail plastic stents: A single tertiary center experience

OBJECTIVES: Pancreatic pseudocysts (PPC) are fluid collections with a well-defined wall that persist for more than 4 weeks inside or around the pancreas as a result of pancreatic inflammation and/or a ductal lesion. PPC have been successfully treated with endoscopic ultrasound (EUS)-guided drainage using different stents. This study aimed to evaluate the safety and efficacy of EUS-guided drainage of PPC using double-pigtail plastic stents in a tertiary hospital. METHODS: Patients with PPC referred for EUS-guided drainage between May 2015 and December 2019 were included in this case series. The primary endpoint was to evaluate the efficacy (clinical success) and safety (adverse events and mortality) of EUS-guided drainage of PPC. Secondary endpoints included technical success and pseudocyst recurrence. RESULTS: Eleven patients (mean age, 44.5±18.98 years) were included in this study. The etiologies for PPC were acute biliary pancreatitis, chronic alcoholic pancreatitis, and blunt abdominal trauma. The mean pseudocyst size was 9.4±2.69 cm. The clinical success rate was 91% (10/11). Adverse events occurred in three of 11 patients (27%). There were no cases of mortality. The technical success rate was 100%. Pseudocyst recurrence was identified in one of 11 patients (9%) at 12 weeks after successful clinical drainage and complete pseudocyst resolution. CONCLUSION: EUS-guided transmural drainage of PPC using double-pigtail plastic stents is safe and effective with high technical and clinical success rates.

Los tumores pseudopapilares del páncreas son tumores de origen pancreático poco frecuentes y de etiología desconocida. Comprenden entre el 0.2 y 2.7% de los carcinomas de páncreas. Hasta 2015 hay 900 casos reportados en la literatura, siendo una minoría en etapa diseminada. Son tumores voluminosos, de bajo potencial maligno, que se presentan con mayor frecuencia en mujeres jóvenes entre 18 y 35 años. Generalmente son asintomáticos o manifiestan clínicamente síntomas inespecíficos como dolor abdominal o presencia de masa abdominal. Anatómicamente se localizan con mayor frecuencia en la cola del páncreas, seguidos por la cabeza y el cuerpo. El tratamiento de elección es la resección quirúrgica. El rol de la quimioterapia en la enfermedad irresecable o avanzada no está claramente definido. Son tumores de excelente pronóstico, con sobrevida a 5 años de casi 100%.Se presentan cuatro casos clínicos y se hace una revisión de la literatura.

Pseudopapillary tumors of the pancreas are tumors of pancreatic origin with a low frequency and an unknown etiology. They account for 0.2 - 2.7 % of all pancreatic carcinomas. Up to 2015 there were approximately 900 well documented cases with only a small minority of them in a metastatic stage. This tumors could reach large proportions and they occur predominantly in young women between 18 and 35 years of age. Most of patients are asymptomatic or have non specific symptoms including abdominal pain or palpable abdominal mass. The most common localization is the tail of the pancreas, followed by the head and the body. Complete resection is the treatment of choice. It is not clearly stablished the rol of chemotherapy in metastatic disease. There are tumors with a favorable prognosis, with an overall 5 year survival rate about 95%. Herein, we report four clinical cases and a literatura review.

Ansa pancreática: desafio no diagnóstico etiológico em paciente jovem com pancreatite grave / Ansa pancreatica: etiological diagnosis challenge in a young patient with severe pancreatitis

A ansa pancreática é uma variação anatômica rara dos ductos pancreáticos. Consiste numa comunicação entre o ducto pancreático principal (Wirsung) e o ducto pancreático acessório (Santorini). Recentemente, estudos têm demonstrado estar essa variação anatômica implicada como fator predisponente e significativamente associada a episódios recorrentes de pancreatite aguda. A pancreatite é uma entidade clínica pouco frequente na infância. Diferente dos adultos, as causas mais comuns incluem infecções virais, por ascaris, medicamentosas, traumas e anomalias estruturais. O objetivo deste estudo foi relatar um caso de pancreatite aguda grave não alcoólica e não biliar, em um paciente jovem de 15 anos, em cuja propedêutica imagenológica evidenciou-se alça, comunicando com os ductos pancreáticos ventral e dorsal, compatível com ansa pancreática.

Ansa pancreatica is a rare anatomical variation of the pancreatic ducts. It consists of communication between the main pancreatic duct (Wirsung) and the accessory pancreatic duct (Santorini). Recently, studies have shown that this anatomical variation is implicated as a predisposing factor and significantly associated with recurrent episodes of acute pancreatitis. Pancreatitis is a rare clinical entity in childhood. Different from that in the adults, the most common causes include viral and ascaris infections, drugs, traumas, and structural abnormalities. The objective of this study was to report a case of a severe non-alcoholic and non-biliary acute pancreatitis in a 15-year-old patient, whose propedeutic imaging showed a loop communicating with the ventral and dorsal pancreatic ducts, consistent with ansa pancreatica.

Pseudocisto pancreático simulando lesão cística neoplásica de cabeça de pâncreas: relato de caso / Pancreatic pseudocyst simulating neoplastic pancreatic head injury: case report

Introdução: os cistos pancreáticos são diagnosticados, em sua maioria, como achados acidentais em pacientes submetidos à exame físico de rotina ou exame radiológico abdominal. As lesões neoplásicas representam 10-15% de todas as lesões pancreáticas. Relato de caso: Relatamos o caso de um paciente com 41 anos de idade apresentando pseudocisto de cabeça de pâncreas com diagnóstico pré-operatório sugestivo de neoplasia sólido-cística. Conclusão: O manejo das neoplasias císticas de pâncreas apresenta-se como um desafio. Os exames de imagem tiveram um papel essencial no diagnóstico diferencial. A ressecção cirúrgica continua sendo padrão ouro para pacientes sintomáticos e com elevada probabilidade de malignidade.

Introduction: cystic lesions of the pancreas are mostly diagnosed as accidental findings in patients undergoing routine physical examination or abdominal radiological examination. Neoplastic pancreatic cysts represent 10-15% of all pancreatic lesions. Case report: We report the case of a 41-year-old patient with a pancreatic head pseudocyst with a preoperative diagnosis suggestive of solid-cystic neoplasm. Conclusion: The management of cystic pancreatic neoplasms is a challenge. Imaging exams played an essential role in the differential diagnosis. Surgical resection remains the gold standard for symptomatic patients with high probability of malignancy.

Infrecuente complicación de páncreas ectópico: obstrucción intestinal por pseudoquiste pancreático en píloro / Infrequent complication of heterotopic pancreas: intestinal obstruction by pancreatic pseudocyst in pylorus

Resumen: Presentamos un caso un hombre de 53 años con antecedentes de reflujo gastroesofágico y pirosis con varias visitas al servicio de urgencias por vómitos, con antecedentes de consumo crónico de alcohol. La TC sin y con contraste endovenoso mostró a nivel del píloro una lesion ovoidea de paredes gruesas con captación similar al tejido pancreático, con un gran componente quístico bien delimitado que condiciona una obstrucción intestinal. La ecografía confirma la presencia de una lesión quística con ecos móviles en su interior. Tras la realización de antrectomía, el estudio histológico revela un pseudoquiste pancreático sobre páncreas ectópico, siendo esta presentación muy infrecuente, con pocos casos descritos hasta la fecha. Conclusión: Los hallazgos clínico-radiológicos con TC y US de páncreas ectópico pueden orientar el diagnóstico, aunque no son concluyentes. El diagnóstico definitivo se realiza mediante estudio histológico.

Abstract: A 53 year-old male with a past history of chronic alcohol intake, presents with an intestinal obstruction. A CT scan shows an ovoid tumor in pylorus with a great cystic component, thick wall and delimited rim, causing gastric retention. Its walls have similar enhancing pattern as the pancreatic tissue. Ultrasound revealed the presence of a cystic tumor with mobile echoes inside. After antrectomy the histological study reports pancreatic pseudocyst hosted in ectopic pancreas. This is an unusual presentation and only a few cases have been reported. Conclusion: The clinical and radiographic findings of ectopic pancreas are non-specific. Definitive diagnostic requires histological study.

Tratamiento del pseudoquiste pancreático / Treatment of pancreatic pseudocyst

El pseudoquiste pancreático corresponde a una complicación alejada de la pancreatitis aguda. En nuestro medio son más frecuentes las de etiología biliar. El pseudoquiste se manifiesta en el 10% de estos pacientes. Presentamos el caso de un paciente con un pseudoquiste pancreático resuelto según abordaje endoscópico. Mediante este caso clínico destacamos el abordaje endoscópico de esta patología como un método seguro para el tratamiento de tal complicación.

Pancreatic psudocyst is a late complication of acute pancreatitis. In our environment, cholelithiasis is the most common cause of pancreatitis, and pancreatic pseudocyst occurs in 10% of these patients. We report the case of a patient with a pancreatic psudocyst treated with endoscopic drainage. We highlight that the endoscopic approach is a safe method to treat this complication.

Intervencionismo endoscópico en la pancreatitis crónica / Endoscopic Intervention in Chronic Pancreatitis

Resumen La pancreatitis crónica es un trastorno irreversible y progresivo del páncreas caracterizado por inflamación, fibrosis y cicatrización. Las funciones exocrinas y endocrinas se pierden, lo que a menudo conduce al dolor crónico. La etiología es multifactorial, aunque el alcoholismo es el factor de riesgo más importante en los adultos. Si se sospecha pancreatitis crónica, la tomografía computarizada con contraste es la mejor modalidad de diagnóstico por imágenes. Aunque los narcóticos y los antidepresivos proporcionan el mayor alivio del dolor, más de la mitad de los pacientes eventualmente requiere una intervención por endoscopia o cirugía. La colangiopancreatografía retrógrada endoscópica es una alternativa eficaz para una variedad de terapias en el tratamiento de enfermedades benignas y malignas del páncreas. En los últimos 50 años, la endoterapia ha evolucionado hasta convertirse en la terapia de primera línea en la mayoría de las enfermedades inflamatorias agudas y crónicas del páncreas. A medida que avanza este campo, es importante que los gastroenterólogos mantengan un conocimiento adecuado de la indicación del procedimiento, mantengan el volumen de procedimiento suficiente para manejar la endoterapia pancreática compleja y comprendan enfoques alternativos a las enfermedades pancreáticas, incluidos el tratamiento médico, la terapia guiada por ecografía endoscópica, el manejo de las estenosis sintomáticas y cálculos, las intervenciones sobre el plexo celíaco y el drenaje de los pseudoquistes pancreáticos.

Abstract Chronic pancreatitis is an irreversible and progressive disorder of the pancreas characterized by inflammation, fibrosis and scarring. Exocrine and endocrine functions are lost often leading to chronic pain. Its etiology is multifactorial, although alcoholism is the most important risk factor in adults. If chronic pancreatitis is suspected, computed tomography with contrast is the best imaging modality. Although narcotics and antidepressants provide the greatest pain relief, more than half of all patients eventually require intervention by endoscopy or surgery. Endoscopic retrograde cholangiopancreatography (ERCP) is an effective alternative for a variety of therapies for treating benign and malignant diseases of the pancreas. In the last 50 years, endoscopic treatment has evolved to become the first-line therapy for most acute and chronic inflammatory diseases of the pancreas. As this field progresses, it has become important for gastroenterologists to keep their knowledge of indications for this procedure up-to-date and to perform a sufficient volume of procedures to allow them to manage complex pancreatic endoscopic therapy. Keeping up-to-date should include an understanding of alternative approaches to pancreatic diseases including medical treatment, therapy guided by endoscopic ultrasound, management of symptomatic stenoses and stones, interventions on the celiac plexus, and drainage of pancreatic pseudocysts.

A pancreatic hemorrhagic pseudocyst with pseudoaneurysm and the role of doppler ultrasonography: a case report

SUMMARY Hemorrhagic pseudocysts with pseudoaneurysms are a rare and fatal complication of chronic pancreatitis due to the erosion of pancreatic to peripancreatic arteries. The timing of the rupture cannot be accurately predicted, but prompt diagnosis and management are essential to prevent further bleeding. We describe the case of a 68-year-old man who presented acute epigastric pain and anemia and had a history of chronic pancreatitis with a pseudocyst. A biliary and pancreas MRI showed an enlarged size of a known pancreatic pseudocyst with internal high signal intensity material. Color-Doppler ultrasonography showed pulsating signals in the pseudocyst, and our final diagnosis was a pseudoaneurysm in the pancreatic hemorrhagic pseudocyst. The pseudoaneurysm was successfully treated with coil embolization of the feeding artery. We report this case of a rare complication of chronic pancreatitis to show that color-Doppler ultrasound is a non-invasive and effective diagnostic tool for pseudoaneurysm, which enables early detection and prompt treatment without the need for invasive diagnostic modalities.

Seguridad y eficacia del drenaje guiado por endosonografía de colecciones pancreáticas usando prótesis plásticas y metálicas tipo LAMS / Safety and efficacy of EUS-guided drainage of pancreatic fluid collections using plastic and lumen apposing metal stents (LAMS)

Background: Pancreatic fluid collections (PFC) are associated with severe acute pancreatitis. After maturation (after 4 weeks) they are classified as pancreatic pseudocyst (PP) and walled-off necrosis (WON). Endoscopic management is associated with lower morbidity and mortality compared with surgery. Aim: To describe the experience of EUS-guided drainage PFC drainage using plastic stent (PS) or metal stent (lumen apposing metal stents, or "LAMS"). Methods: Retrospective, observational study, between 2016-2019. Results: 17 patients in total. 8 cases were symptomatic PP and 9 were WON. Age 12-72 years. 12 cases in men. Indications: abdominal pain 5 cases and infection 11. The 8 cases of PFC were drained successfully using PS, without adverse effects. Regarding WON drainage, 3 cases were managed with PS and 6 with LAMS. In 5 cases, complementary endoscopic necrosectomy was required. A patient with LAMS required complementary surgical cleaning ("step-up") to treat collections far from the LAMS. Complications: one case of PS presented pigment occlusion with superinfection and another case presented migration to the stomach. Regarding LAMS, one case presented self-limited bleeding, another case presented obstruction of the stent with infection, which was managed endoscopically and with antibiotics. Conclusion: The endoscopic management of PFC is effective and safe, with plastic and metal stent (LAMS). The choice of type of stent depends on the characteristics of PFC (liquid vs solid), center experience and costs.

Introducción: Las colecciones pancreáticas (CP) se asocian a pancreatitis agudas graves. Luego de su maduración (después de las 4 semanas) se clasifican en pseudoquistes (PQ) y necrosis encapsulada (NE). El manejo endoscópico se asocia a menor morbimortalidad comparado con el quirúrgico. Objetivo: Describir la experiencia del drenaje de CP mediante el uso de prótesis plásticas (PP) o metálicas (lumen apposing metal stents, o "LAMS") mediante endosonografía. Método: Estudio retrospectivo, observacional, entre 2016-2018. Resultados: 17 pacientes en total. Ocho casos fueron PQ sintomáticos y 9 NE. Edad 12-72 años (12 casos en hombres). Indicaciones: dolor abdominal 5 casos e infección 11. Los 8 casos de PQ fueron drenados exitosamente con PP, sin efectos adversos. En relación con el drenaje de NE, 3 casos fueron manejados con PP y 6 con LAMS. En 5 casos se requirió necrosectomía endoscópica complementaria. Un paciente con LAMS requirió aseo quirúrgico complementario por colecciones alejadas al LAMS. En relación con las complicaciones, un caso de PP presentó oclusión del pigtail con sobreinfección y otro presentó migración al estómago. Respecto a LAMS, un caso presentó sangrado autolimitado y otro caso obstrucción de la prótesis con sobreinfección, que fue manejada endoscópicamente y con antibióticos. Conclusión: El manejo endoscópico de las CP es efectiva y segura, tanto con prótesis plásticas como metálicas (LAMS). La elección de la prótesis depende de las características de la lesión (líquido vs sólido), experiencia del centro y costos.

Multiple Congenital Pancreatic Cysts in a Neonate

Congenital pancreatic cysts are rare in newborn babies, and this makes prenatal diagnosis difficult. Diagnosis can be delayed for a few months after birth until the infant presents with an abdominal mass, abdominal distension, or vomiting due to gastric outlet obstruction. Excision of the cyst is the treatment of choice. A congenital pancreatic cyst should be considered if the fetus has an abdominal cyst without a definite origin. A prompt diagnosis is crucial to prevent fatal complications such as cholangitis, pancreatitis, cyst rupture, and peritonitis. We report a case of neonate with multiple congenital pancreatic cysts suspected prenatally to be stomach diverticulum or duplication cysts of the intestine.

Abdominal pain without bruising or sign of trauma: pancreatic injuries in children is difficult to predict

Pancreatic injuries due to trauma in children are rare. An early diagnosis is difficult as the signs and symptoms are insidious, but delays in diagnosis can lead to significant complications. We report a case of a child who visited the emergency department with aggravating abdominal pain. The physicians first diagnosed the abdominal pain as being caused by a disease in the emergency department, but the patient was subsequently diagnosed with pancreatic injury. Clinicians should be aware of a possible trauma in children who complain of vague abdominal pain even in the absence of corresponding history.

Comparison of Clinical Outcomes between Plastic Stent and Novel Lumen-apposing Metal Stent for Endoscopic Ultrasound-Guided Drainage of Peripancreatic Fluid Collections

BACKGROUND/AIMS: Endoscopic ultrasound (EUS)-guided transmural drainage for peripancreatic fluid collections (PFCs) has gained wide acceptance as a nonsurgical intervention. Although a lumen-apposing metal stent (LAMS) was recently introduced, there are few data comparing the clinical outcomes between LAMS and plastic stent (PS) drainage. METHODS: Endoscopy databases of all patients who had undergone EUS-guided drainage for PFCs were searched and the clinical outcomes of EUS-guided drainage according to stent-type used were compared. RESULTS: A total of 27 patients (median age, 56 years) with PFCs underwent EUS-guided transmural drainage between January 2011 and December 2017. Of these, 17 underwent PS placement and 10 underwent LAMS placement. There was no significant difference in the technical success rate between the 2 groups (94.1% vs. 100%, p=1.0). Procedure time was shorter in the LAMS group compared to that in the PS group (10.6±2.5 min vs. 21.4±9.5 min, p=0.002). Among subjects with clinical success, recurrence of PFC after stent removal occurred in 5 of 12 patients with PS and 4 of 10 with LAMS, without statistical difference (41.7% vs. 40.0%, p=1.0). CONCLUSIONS: Although our study showed similar clinical outcomes for LAMS and PS, further prospective trials are required to validate the superiority of LAMS.

The Genomic Landscape and Its Clinical Implications in Hepatocellular Carcinoma

The pathogenesis of hepatocellular carcinoma (HCC) is a complex process. During the last decade, advances in genomic technologies enabled delineation of the genomic landscape of HCC, resulting in the identification of the common underlying molecular alterations. The tumor microenvironment, regulated by inflammatory cells, including cancer cells, stromal tissues, and the surrounding extracellular matrix, has been extensively studied using molecular data. The integration of molecular, immunological, histopathological, and clinical findings has provided clues to uncover predictive biomarkers to enhance responses to novel therapies. Herein, we provide an overview of the current HCC genomic landscape, previously identified gene signatures that are used routinely to predict prognosis, and an immune-specific class of HCC. Since biomarker-driven treatment is still an unmet need in HCC management, translation of these discoveries into clinical practice will lead to personalized therapies and improve patient care, especially in the era of targeted and immunotherapies.
