Advances in the study of postpancreatectomy acute pancreatitis / 中华外科杂志

Postpancreatectomy acute pancreatitis (PPAP) is an acute inflammation of the remnant pancreas in the early postoperative period caused by a variety of factors. With the progress of related research,PPAP has been confirmed as an independent risk factor for many severe complications such as postoperative pancreatic fistula. In some cases, it progresses to necrotizing PPAP, increasing the risk of mortality. Currently, the International Study Group for Pancreatic Surgery has standardized and graded PPAP as an independent complication, taking into account factors including serum amylase, radiological features, and clinical impact. This review summarizes how the concept of PPAP was proposed, as well as the latest progress in the research related to its etiology, prognosis, prevention, and treatment. However, given the large heterogeneity of relevant studies and the fact that they were mostly retrospective, in the future, it is necessary to place more emphasis on PPAP and elucidate the problems through more standardized studies to optimize strategies for the prevention and management of complications after pancreatic surgery.

Microangiopatía trombótica como complicación de una pancreatitis aguda / Thrombotic microangiopathy as a complication of acute pancreatitis / Microangiopatia trombótica como complicação da pancreatite aguda

La púrpura trombótica trombocitopénica (PTT) es una microangiopatía trombótica poco frecuente, que se caracteriza por anemia hemolítica y plaquetopenia, con una elevada morbimortalidad. Su forma más frecuente es la PTT inmune, también denominada adquirida, provocada por la deficiencia de la enzima disintegrin-like and metalloprotease with thrombospondin type 1 motif 13 (ADAMTS13) secundaria a la presencia en plasma de autoanticuerpos. Presentamos el caso de un paciente con diagnóstico de pancreatitis aguda (PA) complicada con PTT, asociación de presentación excepcional en la práctica clínica.

Summary: Thrombotic thrombocytopenic purpura is rather an unusual thrombotic microangiopathy characterized by hemolytic anemia and plateletopenia which results in high morbimortality rates. The most frequent form of this disease is immune thrombotic thrombocytopenic purpura, also known as acquired thrombotic thrombocytopenic purpura, which is caused by enzime deficiency disintegrin-like and metalloprotease with thrombospondin type 1 motif 13 (ADAMTS13) that is secondary to antibodies in plasma. The study presents the case of a patient with a diagnosis of acute pancreatitis with a rare complication of thrombotic thrombocytopenic purpura which is exceptional in the clinical practice.

A púrpura trombocitopênica trombótica (PTT) é uma microangiopatia trombótica rara, caracterizada por anemia hemolítica e trombocitopenia, com alta morbimortalidade. Sua forma mais comum é a TTP imune, também conhecida como adquirida, que é causada pela deficiência da enzima ADAMTS13 (em inglês A disintegrin-like and metalloprotease with thrombospondin type 1 motif no. 13) secundária à presença de autoanticorpos no plasma. Apresentamos o caso de um paciente com diagnóstico de pancreatite aguda (PA) complicada por PTT, associação com apresentação excepcional na prática clínica.

Crisis hipercalcémica como causa de pancreatitis aguda / Hypercalcemia as a cause of acute pancreatitis. Report of one case

Alimentação oral e gástrica na pancreatite aguda grave / Gastric and oral feeding in severe acute pancreatitis

ABSTRACT BACKGROUND: There is controversy about the initiation of gastric or oral feeding in patients with severe acute pancreatitis (SAP) because they could increase pancreatic stimulation and exacerbate symptoms and complications. OBJECTIVE: To describe the clinical characteristics and results of patients with SAP who underwent gastric tube or oral feeding versus parenteral or jejunal feeding. METHODS: A retrospective study was carried out on patients over 18 years old with SAP diagnostic, who had been treated in critical care units. We excluded patients coming from other hospitals and those with incomplete medical records. RESULTS: Thirty patients with SAP were included, fifty three percent of them tolerated the gastric tube or oral feeding, and most of them were females and older than patients who received parenteral or jejunal feeding. Other clinical characteristics and outcomes were similar in both groups. Conclusion: Gastric tube or oral feeding is no absolute contraindication for SAP.

RESUMO CONTEXTO Há controvérsias sobre o início da alimentação gástrica ou oral em pacientes com pancreatite aguda grave (PAG), pois elas podem aumentar a estimulação pancreática e exacerbar os sintomas e complicações. OBJETIVO Descrever as características clínicas e os resultados de pacientes com PAG submetidos à alimentação por sonda gástrica ou via oral versus alimentação parenteral ou jejunal. MÉTODOS Foi realizado um estudo retrospectivo em pacientes maiores de 18 anos com diagnóstico de PAG, atendidos em unidades de terapia intensiva. Excluímos pacientes procedentes de outros hospitais e aqueles com prontuário incompleto. RESULTADOS Trinta pacientes com PAG foram incluídos, 53% deles toleravam a sonda gástrica ou alimentação via oral, e a maioria era do sexo feminino e tinha mais idade do que os pacientes que receberam alimentação parenteral ou jejunal. Outras características clínicas e resultados foram semelhantes em ambos os grupos. CONCLUSÃO A sonda gástrica ou alimentação oral não é contra-indicação absoluta para PAG.

Pancreatitis aguda en pediatría como complicación de síndrome inflamatorio multisistémico asociado a COVID-19: un caso clínico / Acute pancreatitis in pediatrics as a complication of multi-systemic inflammatory syndrome associated with COVID-19: A case report

En abril de 2020, en informes provenientes del Reino Unido se notificó una presentación en niños similar a la enfermedad de Kawasaki incompleta o al síndrome de choque tóxico asociados con la enfermedad por el nuevo coronavirus (COVID-19). Desde entonces, ha habido informes de niños afectados de manera similar en otras partes del mundo. En la actualidad, la afección se ha denominado síndrome inflamatorio multisistémico asociado a COVID-19 en niños (SIM-C). Por otra parte, se notificaron casos de pancreatitis aguda, en su mayoría en pacientes adultos, en el contexto de la infección aguda por el coronavirus 2 causante del síndrome respiratorio agudo grave (SARS-COV-2), causada por efectos citopáticos directos o respuestas celulares indirectas sistémicas inflamatorias e inmunomediadas. Sin embargo, son escasas las notificaciones en las que se describe el cuadro de pancreatitis aguda durante el SIM-C. Se describe aquí la presentación clínica, el tratamiento y la evolución de una paciente de 9 años que presentó un cuadro de pancreatitis aguda en el contexto del SIM-C.

In April 2020, UK studies informed a condition in children similar to incomplete Kawasaki disease or toxic shock syndrome. From that time onwards, papers on children suffering from similar conditions have been published in different parts of the world. Today the disease is named multisystem inflammatory syndrome in children (MIS-C) associated with Covid-19. Acute pancreatitis was reported mainly in adult patients with acute SARS-COV-2 infection developing direct cytopathic effect or immune-mediated and systemic inflammatory indirect cellular responses. However, there are only a few studies, which describe the acute pancreatitis case during MIS-C period. The present article describes the clinical presentation, therapy and evolution of a 9 years-old female patient developing an acute pancreatitis case suffering from MIS-C

Pancreatitis aguda. Diagnóstico y enfrentamiento inicial en la práctica clínica / Acute pancreatitis. Diagnosis and initial approach in clinical practice

Acute pancreatitis is a prevalent disease, with variable clinical course: several patients recover quickly and uneventfully, while others require treatment in critical care units with long hospital stay and even with a considerable mortality. The patient's symptoms, laboratory tests and radiological images allow diagnosis without major difficulties. However, early identification of more severe cases can be difficult, and it determines the adequate selection of the hospitalization unit and the quick initiation of the appropriate therapy. In this paper we give some practical treatment guidelines for the everyday clinical practice: immediate severity stratification, fluid replacement and pain control. Early enteral nutrition, monitorization of severe cases in critical care units, adequate therapeutic but no prophylactic use of antibiotics assures the best treatment results. (AU)

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.

Preeclampsia as an inaugural manifestation of primary hyperparathyroidism: A case report / Pré-eclâmpsia como manifestação inaugural de hiperparatiroidismo primário: Um caso clínico

Abstract Primary hyperparathyroidism is an endocrine disorder characterized by hypercalcemia and elevated or inappropriately normal levels of parathyroid hormone. The diagnosis is based on a biochemical evaluation, and a neck ultrasound is the first choice during pregnancy to access the parathyroid glands. Manifestations during pregnancy are rare and can be present with life-threatening complications, so the diagnosis is challenging. The conservative treatment is limited, and there is not enough data about its safety and efficacy during pregnancy. Surgery is the only curative treatment, and a parathyroidectomy performed during the second or third trimesters is considered safe. Recently, some authors suggested an association between primary hyperparathyroidism and preeclampsia. We describe a case of preeclampsia with severe features at 27 weeks of gestational age. The severity of the preeclampsiamotivated an early termination of the pregnancy by cesarean section. During the postpartum period, the patient presented life-threatening complications, such as severe hypercalcemia and acute pancreatitis. An ultrasound exam found two parathyroid nodules, suggestive of parathyroid adenomas. The patient recovered after the pharmacological correction of the calcemia levels.

Resumo O hiperparatiroidismo primário é umdistúrbio endócrino caraterizado pela elevação do cálcio sérico associada a níveis de paratormona elevados ou inapropriadamente normais. O diagnóstico é baseado em análises bioquímicas, e, na gravidez, o exame de imagem de primeira linha é a ecografia cervical. É uma doença rara na gravidez, e pode se apresentar com complicações ameaçadoras de vida, pelo que o seu diagnóstico é desafiante. O tratamento médico disponível é limitado, havendo poucos dados relativos à sua eficácia e segurança na gravidez. A cirurgia é o único tratamento curativo, e pode ser realizada no segundo ou terceiro trimestres. Tem sido descrita uma relação entre hiperparatiroidismo primário e pré-eclâmpsia. Apresenta-se um caso de uma grávida de 27 semanas com pré-eclâmpsia com critérios de gravidade, o que obrigou ao término da gravidez por cesariana. Verificou-se agravamento clínico no período pós-parto, com aparecimento de complicações graves, tais como hipercalcemia grave e pancreatite aguda. Ecograficamente, constataram-se duas massas paratiróideias sugestivas de adenomas da paratiroide. A doente recebeu tratamento médico, e teve melhora apenas após a correção dos níveis de cálcio sérico.

Comparación entre uso y no uso de antibióticos profilácticos en pancreatitis aguda grave: ensayo clínico aleatorizado: reporte preliminar / Comparison between use and non-use of prophylactic antibiotics in severe acute pancreatitis: randomized clinical trial: preliminary report

Resumen Introducción: La pancreatitis aguda es una enfermedad frecuente en el país, con una tasa de mortalidad de 10%-30%. La administración profiláctica de antibióticos ha sido parte del tratamiento de pancreatitis aguda grave (PAG), por la teórica prevención de complicaciones infecciosas y reducción de mortalidad. Sin embargo, la evidencia científica disponible es controversial. Objetivo: Demostrar que los antibióticos profilácticos no disminuyen las complicaciones locales y/o sistémicas, requerimiento de Unidad de Paciente Crítico (UPC), ni mortalidad en PAG. Definimos PAG como APACHE II ≥ 8 o PCR ≥ 150 o falla multiorgánica. Material y Método: Ensayo clínico aleatorizado, con aleatorización simple mediante tabla electrónica (uso o no uso de antibióticos profilácticos) de pacientes con PAG. En el grupo que usó antibióticos profilácticos se utilizó ciprofloxacino y metronidazol por 7 días. El resto del manejo no tuvo variación. Resultados: n = 71, dos grupos aleatorizados; Grupo 1 (n = 35), sin uso de antibióticos profilácticos, y grupo 2 (n = 36) con uso de profilaxis antibiótica. 12 pacientes (16%) requirieron UPC; 6 pacientes del grupo 1, y 6 del grupo 2 (p = 0,957). Siete pacientes (9,8%) tuvieron algún tipo de complicación, 3 en el grupo 1 y 4 en el grupo 2 (p = 0,516). El promedio de estancia hospitalaria fue 18,2 ± 9,5 días en el grupo 1, y 22,6 ± 29.2 días en el grupo 2 (p = 0,495). Mortalidad: 1 paciente (1,41%) en el grupo 2 (p = 0,493). Conclusión: En este reporte preliminar, el uso de antibióticos profilácticos en PAG no mostró reducir las complicaciones, necesidad de cama en UPC, ni la mortalidad.

Introduction: Acute pancreatitis is a common disease in the country, with a mortality rate of 10%-30%. The prophylactic administration of antibiotics has been part of the treatment of severe acute pancreatitis (SAP), due to the theoretical prevention of infectious complications and mortality reduction. However, the available scientific evidence is controversial. Objective: To demonstrate that prophylactic antibiotics do not reduce local and/or systemic complications, critical patient unit (CPU) requirement, or mortality in SAP. We define SAP as APACHE II ≥ 8 or PCR ≥ 150° or multiorgan failure. Material and Method: Randomized clinical trial, with simple randomization by electronic table (use or non-use of prophylactic antibiotics) of patients with SAP. In the group that used prophylactic antibiotics, ciprofloxacin and metronidazole were used for 7 days. Results: n = 71, two randomized groups; Group 1 (n = 35), without the use of prophylactic antibiotics, and group 2 (n = 36) with the use of antibiotic prophylaxis. 12 patients (16%) required CPU; 6 patients from group 1, and 6 from group 2 (p = 0.957). Seven patients (9.8%) had some type of complication, 3 in group 1 and 4 in group 2 (p = 0.516). The average hospital stay was 18.2 ± 9.5 days in group 1, and 22.6 ± 29.2 days in group 2 (p = 0.495). Mortality: 1 patient (1.41%) in group 2 (p = 0.493). Conclusion: In this preliminary report, the use of prophylactic antibiotics in SAP was not shown to reduce complications, need for bed in CPU, or mortality.

Controversias en la terapia nutricional de la pancreatitis aguda grave / Controversies in nutrition therapy of severe acute pancreatitis

La clasificación de la severidad de la pancreatitis aguda ha cambiado con la actualización de Atlanta del 2012. Las recomendaciones de terapia nutricional en los casos de pancreatitis aguda grave no están sustentadas en estudios con alto nivel de evidencia, en los estudios se incluyen pacientes con los diferentes grados de severidad, se usa la clasificación de Atlanta 2002 para definir la pancreatitis aguda grave y, en la mayoría de los estudios experimentales, los controles son pacientes con nutrición parenteral. Se realiza una revisión narrativa de la evidencia actual publicada, analizando las características clínico epidemiológica de los pacientes y los resultados obtenidos. Así, se proponen características que deben ser consideradas en estudios futuros sobre el tema.

The classification of the severity of acute pancreatitis has changed with respect to the Atlanta update of 2012. The recommendations for nutritional therapy in cases of severe acute pancreatitis are not supported by high-level studies, as studies contain a mix of patients with different degrees of severity. The Atlanta 2002 classification is used to define severe acute pancreatitis and, in most of experimental studies, controls are patients with parenteral nutrition. A narrative review of the current published evidence is carried out analyzing the clinical and epidemiological characteristics of the patients in these results and characteristics to be included in future studies are proposed.

Pancreatitis aguda. Artículo de revisión / Acute Pancreatitis. Review Article

La pancreatitis aguda (PA) se define como un proceso inflamatorio agudo del páncreas el cual puede comprometer otros órganos y tejidos. El diagnóstico requiere al menos 2 de las siguientes características: dolor abdominal de moderada a fuerte intensidad, acompañado de náuseas y vómito; evidencia bioquímica de pancreatitis y/o evidencia por imágenes a través de tomografía axial computarizada dinámica (TACD) y/o la resonancia magnética (RM) del páncreas. Es la enfermedad gastrointestinal aguda más común que requiere ingreso hospitalario, siendo la evolución favorable en la mayoría de los casos (80%). Sin embargo, la pancreatitis necrotizante puede desarrollarse en hasta el 20% de los pacientes y se asocia con tasas significativas de insuficiencia orgánica temprana (38%). Los trastornos metabólicos y el ayuno comprometen el estado nutricional lo que podría agravar el curso de la enfermedad, por ello la vía de administración de la terapia nutricional ha demostrado tener un impacto en la evolución de los pacientes. Ahora existe una mejor definición de cuales pacientes con PA necesitan una terapia nutricional agresiva y cuales son aquellos que probablemente se beneficiarán de una nutrición enteral temprana(AU)

Acute pancreatitis (AP) is defined as an acute inflammatory process of the pancreas which can compromise other organs and tissues. The diagnosis requires at least 2 of the following characteristics: moderate to severe abdominal pain, accompanied by nausea and vomiting; biochemical evidence of pancreatitis and/or imaging evidence through dynamic computed axial tomography (TACD) and/or magnetic resonance imaging (MRI) of the pancreas. It is the most common acute gastrointestinal disease that requires hospital admission, with a favorable evolution in most cases (80%). However, necrotizing pancreatitis can develop in up to 20% of patients and is associated with significant rates of early organ failure (38%). Metabolic disorders and fasting compromise the nutritional status which could aggravate the course of the disease, therefore the route of administration of nutritional therapy has been shown to have an impact on the evolution of patients. There is now a better definition of which AP patients need aggressive nutritional therapy and which are likely to benefit from early enteral nutrition(AU)

Pancreatitis aguda: fisiopatología y manejo inicial / Acute pancreatitis: pathophysiology and initial management

Resumen La pancreatitis aguda es un trastorno intracelular del calcio en las células pancreáticas, el cual constituye la vía final común de múltiples estímulos etiopatogénicos y puede desencadenar cambios necroinflamatorios locales, efectos multisistémicos y compromiso en órganos distantes. Todo esto lleva a los pacientes a múltiples complicaciones por disfunción orgánica e infección. El diagnóstico adecuado y oportuno, el abordaje según severidad y la optimización de la terapia nutricional, así como una adecuada analgésica, reanimación hídroelectrolítica, detección de disfunción orgánica y de complicaciones locales e infecciosas, determinan el desenlace clínico de dicha patología. Se realizó una revisión narrativa incluyendo estudios clínicos, guías de manejo, protocolos y revisiones pertinentes, y se aporta un enfoque desde el punto de vista de medicina crítica para el abordaje inicial de esta patología.

Abstract Acute pancreatitis is an intracellular calcium disorder in pancreatic cells, which constitutes the final common pathway of multiple etiopathogenic stimuli and can trigger local necroinflammatory changes, multisystemic effects and compromise distant organs. All of this leads to multiple complications due to organ dysfunction and infection in patients. The adequate and opportune diagnosis, the approach according to severity and the optimization of the nutritional therapy; as well as an adequate analgesic, hydroelectrolytic resuscitation, the detection of organic dysfunction and of local and infectious complications, determine the clinical outcome of this pathology. A narrative review was carried out including clinical studies, management guidelines, protocols and reviews. An initial approach for this pathology, from the critical medicine point of view, is provided.

Osificación heterotópica de cadera asociada a pancreatitis aguda severa: reporte de un caso / Hip heterotopic ossification associated with severe acute pancreatitis: a case report

La osificación heterotópica (OH), es la formación anormal de hueso maduro dentro de tejidos blandos extra esqueléticos donde normalmente no existe tejido óseo. Varias formas de OH han sido descritas de acuerdo a su presentación clínica, localización y ocurrencia progresiva o aislada. Su presentación en pacientes sometidos a inmovilización prolongada en el contexto de coma farmacológicamente inducido, en ausencia de lesiones del sistema nervioso central, es poco habitual. Presentamos el caso de una paciente de 40 años, sexo femenino, sin antecedentes mórbidos, que presenta episodio de pancreatitis aguda grave, manejada en UCI. Producto de lo anterior, requiere coma farmacológicamente inducido por 3 meses y hospitalizaciones reiteradas y prolongadas durante los 10 meses siguientes. Durante 3 años desde la resolución de su cuadro inicial evoluciona con alteración progresiva de la marcha y rigidez de la extremidad inferior derecha, sin eventos traumáticos durante ese período. Se objetiva mediante radiografía y TAC foco de OH coxofemoral derecha. Se resuelve de forma quirúrgica y biopsia de pieza operatoria confirma el diagnóstico. La paciente logra buena recuperación posterior. NIVEL DE EVIDENCIA: IV

Heterotopic ossification (HO) is the abnormal formation of mature bone within extraskeletal soft tissues where bone does not exist. Various presentation of HO have been described according to the clinical settings and location of the lesions, and progressive or isolated occurrence. A rare form of presentation occurs in induced coma patients with long-term immobilization and without central nervous system injuries. We present the case of a 40 years old female patient, without previous morbidity, who develop a severe acute pancreatitis. The patient requires an intensive care unit management (ICU) and a 3-month pharmacology induced coma and reiterative and prolonged hospitalizations during the next 8 months. During 3 years after resolution of her base disease, patient develops a progressive step claudication and a hip rigidity in adduction and external rotation. A coxofemoral HO focus is confirmed by radiology and CT. A surgical treatment of HO was performed, and the initial diagnose confirmed by anatomic pathology after biopsy of the injury. Patient had a favorable outcome.

Pancreatitis y apendicitis aguda como complicación en una paciente con enfermedad mixta del tejido conectivo / Pancreatitis and acute appendicitis as a complication in a patient with mixed connective tissue disease

Introducción: la enfermedad mixta del tejido conectivo es una afección que incluye manifestaciones clínicas de diversas enfermedades reumáticas. Se caracteriza sobre todo por la presencia de afectación en todos los órganos y sistemas de órganos del cuerpo humano. Las complicaciones relacionadas con el aparato digestivo han sido señaladas como una de las que con mayor frecuencia se presentan. La pancreatitis y la apendicitis suelen presentarse de forma aislada, pero al presentarse al unísono complican más aún la evolución del paciente. Objetivo: dar a conocer los elementos clínicos, de laboratorio e imagenológicos que posibilitan llegar al diagnóstico de apendicitis y pancreatitis en una paciente con enfermedad mixta del tejido conectivo. Caso clínico: se presenta el caso de una paciente de 29 años de edad con diagnóstico de enfermedad mixta del tejido conectivo de 3 años de evolución que es remita al servicio de emergencia con elementos clínicos, de laboratorio e imagenológicos que permiten llegar al diagnóstico de una apendicitis y pancreatitis de presentación conjunta. Conclusiones: la enfermedad mixta del tejido conectivo es una enfermedad sistémica que cursa con una amplia variedad de manifestaciones clínicas y complicaciones. Los procesos agudos como la apendicitis y la pancreatitis suponen un peligro sobreañadido y un factor desencadenante de la actividad de la enfermedad(AU)

Introduction: mixed connective tissue disease is a condition that includes clinical manifestations of various rheumatic diseases. It is characterized above all by the presence of affectation in all organs and organ systems of the human body. Complications related to the digestive system have been identified as one of the most frequent. Pancreatitis and appendicitis usually occur in isolation, but when presented in unison, they complicate the evolution of the patient even more. Objective: to present the clinical, laboratory and imaging elements that make it possible to reach the diagnosis of appendicitis and pancreatitis in a patient with mixed connective tissue disease. Clinical case: the case of a 29-year-old patient with a diagnosis of mixed connective tissue disease of 3 years of evolution is presented, which is referred to the emergency service with clinical, laboratory and imaging elements that allow to reach the diagnosis of a appendicitis and pancreatitis of joint presentation. Conclusions: Mixed connective tissue disease is a systemic disease that presents with a wide variety of clinical manifestations and complications. Acute processes such as appendicitis and pancreatitis pose an added danger and a triggering factor in the activity of the disease(AU)

Intramural duodenal hematoma secondary to pancreatitis: case report and review of the literature

ABSTRACT CONTEXT: Spontaneous intramural duodenal hematoma is uncommon and is usually associated with coagulopathy, anticoagulant therapy and endoscopic procedures. The aim here was to describe a case of intramural duodenal hematoma caused by chronic exacerbation of pancreatitis. CASE REPORT: A 46-year-old male with chronic alcoholic pancreatitis was admitted to hospital due to abdominal pain, melena and low hemoglobin. An intramural duodenal hematoma with active bleeding was detected and selective angioembolization was warranted. The patient evolved with a perforated duodenum and underwent laparotomy with exclusion of the pylorus and Roux-en-Y gastrojejunostomy. He was discharged nine days later. CONCLUSION: Intramural duodenal hematoma is a rare complication of pancreatitis. Selective embolization is the preferred treatment for hemorrhagic complications of pancreatitis. However, the risk of visceral ischemia and perforation should be considered.
