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.

Familial chylomicronemia syndrome-induced acute necrotizing pancreatitis during pregnancy

Abstract Acute pancreatitis is a rare condition in pregnancy, associated with a high mortality rate. Hypertriglyceridemia represents its second most common cause.We present the case of a 38-year-old woman in the 24th week of gestation with a history of hypertriglyceridemia and recurrent episodes of pancreatitis. She was admitted to our hospital with acute pancreatitis due to severe hypertriglyceridemia. She was stabilized and treated with fibrates. Despite her favorable clinical course, she developed a second episode of acute pancreatitis complicated by multi-organ dysfunction and pancreatic necrosis, requiring a necrosectomy. The pregnancy was ended by cesarean section, after which three plasmapheresis sessions were performed. She is currently asymptomatic with stable triglyceride levels. Acute pancreatitis due to hypertriglyceridemia represents a diagnostic and therapeutic challenge in pregnant women, associated with serious maternal and fetal complications. When primary hypertriglyceridemia is suspected, such as familial chylomicronemia syndrome, the most important objective is preventing the onset of pancreatitis.

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.

Acute Pancreatitis Complicated by Sheehan's Syndrome: A Case Report and Literature Review / 中国医学科学杂志(英文版)

A 44-year-old woman was transferred to the ICU of the First Affiliated Hospital of Jinan University for 2 days of persistent epigastric pain and 7 hours of unconsciousness. Her admission diagnosis was severe acute necrotizing pancreatitis (hypertriglyceridemia type) with multiple organ dysfunctions. The results of CT revealed a small area of necrotizing pancreatitis, which was not consistent with the severe clinical manifestations. Considering lack of hair and history of postpartum hemorrhage, hormone examination was carried out. According to the results of the examination, she was further diagnosed as Sheehan's syndrome and pituitary crisis. After hormone replacement therapy, her condition improved rapidly.

Minimally invasive endoscopic treatment of necrotizing pancreatitis: A case report with images and review of the literature / Tratamento endoscópico minimamente invasivo: relato de caso e revisão da literatura

Summary Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.

Resumo Pancreatite necrosante com coleções pode ocorrer como complicação da pancreatite aguda.

Neste artigo, mostramos um caso grave de necrose pancreática com ótima resolução clínica após drenagem endoscópica.

Pancreatic Necrosis and Gas in the Retroperitoneum: Treatment with Antibiotics Alone

OBJECTIVE: To present our experience in the management of patients with infected pancreatic necrosis without drainage. METHODS: The records of patients with pancreatic necrosis admitted to our facility from 2011 to 2015 were retrospectively reviewed. RESULTS: We identified 61 patients with pancreatic necrosis. Six patients with pancreatic necrosis and gas in the retroperitoneum were treated exclusively with clinical support without any type of drainage. Only 2 patients had an APACHE II score >8. The first computed tomography scan revealed the presence of gas in 5 patients. The Balthazar computed tomography severity index score was >9 in 5 of the 6 patients. All patients were treated with antibiotics for at least 3 weeks. Blood cultures were positive in only 2 patients. Parenteral nutrition was not used in these patients. The length of hospital stay exceeded three weeks for 5 patients; 3 patients had to be readmitted. A cholecystectomy was performed after necrosis was completely resolved; pancreatitis recurred in 2 patients before the operation. No patients died. CONCLUSIONS: In selected patients, infected pancreatic necrosis (gas in the retroperitoneum) can be treated without percutaneous drainage or any additional surgical intervention. Intervention procedures should be performed for patients who exhibit clinical and laboratory deterioration.
