Pancreatoduodenectomía de urgencia. Revisión de 2 casos clínicos

Introducción: La pancreatoduodenectomía de urgencia (PDDU) es una cirugía reservada para lesiones graves pancreatoduodenales secundarias a trauma, lesiones inflamatorias o posterior a procedimientos endoscópicos. Objetivo: Describir dos casos clínicos en los que se realizó PDDU. Casos Clínicos: Se reportan 2 casos clínicos en los cuales se requirió una PDD. En el primer caso secundario a úlcera duodenal perforada que comprometía más del 50% del lumen asociado a biliperitoneo y fistula duodenal sin control; y en el segundo, a consecuencia de un trauma por herida de bala con perforación duodenal, íleon distal y desgarro de 1,5 cm en cabeza de páncreas. Discusión: En la actualidad no existe un consenso sobre las indicaciones de PPDU, sin embargo esta compleja cirugía representa una opción de tratamiento en pacientes bien seleccionados, cuando la cirugía de control de daños y los intentos de controlar la necrosis y fistulas duodenales han fracasado. Conclusión: El tratamiento de una lesión pancreática y duodenal compleja puede requerir PDDU. Sin embargo, en pacientes inestables se debe considerar una cirugía en dos tiempos por un equipo de cirujanos experimentados.

Introduction: Emergency pancreaticoduodenectomy (UPDD) is a surgery reserved for severe pancreaticoduodenal injuries secondary to trauma, inflammatory injuries or after endoscopic procedures. Aim: To describe two clinical cases in which PDDU was performed. Clinical Cases: 2 clinical cases are reported in which a PDDU was required. The first case was secondary to a perforated duodenal ulcer that compromised more than 50% of the lumen associated with biliperitoneum uncontrolled duodenal fistula; in the second one, as a consequence of a gunshot wound trauma with duodenal perforation, distal ileum and a 1.5 cm tear in the head of pancreas. Discussion: Currently there is no consensus on the indications for UPDD, however this complex surgery represents a treatment option in well-selected patients, when damage control surgery and attempts to control necrosis and duodenal fistulas have failed. Conclusión: Treatment of a complex pancreatic and duodenal injury may require pancreatoduodenectomy. However, in unstable patients, a two-stage surgery should be considered by an experienced surgical team.

Pancreatic damage control: the pancreas is simple don't complicate it / El control de daños en el páncreas es simple. No complique las cosas

Abstract Pancreatic trauma is a rare but potentially lethal injury because often it is associated with other abdominal organ or vascular injuries. Usually, it has a late clinical presentation which in turn complicates the management and overall prognosis. Due to the overall low prevalence of pancreatic injuries, there has been a significant lack of consensus among trauma surgeons worldwide on how to appropriately and efficiently diagnose and manage them. The accurate diagnosis of these injuries is difficult due to its anatomical location and the fact that signs of pancreatic damage are usually of delayed presentation. The current surgical trend has been moving towards organ preservation in order to avoid complications secondary to exocrine and endocrine function loss and/or potential implicit post-operative complications including leaks and fistulas. The aim of this paper is to propose a management algorithm of patients with pancreatic injuries via an expert consensus. Most pancreatic injuries can be managed with a combination of hemostatic maneuvers, pancreatic packing, parenchymal wound suturing and closed surgical drainage. Distal pancreatectomies with the inevitable loss of significant amounts of healthy pancreatic tissue must be avoided. General principles of damage control surgery must be applied when necessary followed by definitive surgical management when and only when appropriate physiological stabilization has been achieved. It is our experience that viable un-injured pancreatic tissue should be left alone when possible in all types of pancreatic injuries accompanied by adequate closed surgical drainage with the aim of preserving primary organ function and decreasing short and long term morbidity.

Resumen El trauma pancreático es un tipo de trauma poco común potencialmente fatal que está asociado con lesiones de órganos abdominales o vasculares. Usualmente, los signos clínicos son tardíos aumentado el riesgo de complicaciones respecto al manejo y al pronóstico general. Debido a la baja prevalencia de la lesión del trauma, no existe consenso entre los cirujanos alrededor del mundo sobre cómo se debe diagnosticar y tratar adecuadamente este desafío quirúrgico. La precisión en el diagnóstico es difícil por la localización anatómica y las manifestaciones clínicas tardías. El abordaje quirúrgico ha ido cambiando de dirección hacia la preservación del órgano para evitar complicaciones secundarias asociada a la perdida de la función exocrina y endocrina, o de potenciales complicaciones postquirúrgicas incluyendo las dehiscencias y fistulas. El objetivo de este artículo es proponer un algoritmo de manejo del trauma pancreático a través de un consenso de expertos. Las lesiones del páncreas pueden ser manejadas con una combinación de maniobras hemostáticas, empaquetamiento pancreático, sutura de la herida y drenaje quirúrgico cerrado. La pancreatectomía distal con la perdida de tejido vital pancreático debe ser evitadas. Los principios generales de la cirugía de control de daños deben ser aplicados cuando sea necesario para un manejo quirúrgico definitivo cuando y solo cuando la estabilización fisiológica haya sido lograda. En nuestra experiencia, el tejido pancreático sano debe preservarse cuando el trauma se asocia de un manejo mediante un drenaje quirúrgico cerrado con el objetivo de preservar la función primaria del órgano y disminuir a corto y largo tiempo las morbilidades.

Pancreatitis aguda como complicación infrecuente de litotricia extracorpórea por ondas de choque. Comunicación de un caso / Acute pancreatitis as an unusual complication of extracorporeal shock wave lithotripsy. A case report / Pancreatite aguda como complicação pouco frequente de litotrícia extracorpórea por ondas de choque. Comunicação de um caso

Resumen: La litotricia extracorpórea por ondas de choque para el tratamiento de la urolitiasis es un tratamiento ampliamente aceptado, pero no exento de complicaciones. La pancreatitis aguda que se desencadena inmediatamente posterior a este procedimiento es infrecuente, pero puede ser una complicación grave que amenaza la vida del paciente. La aparición aguda de dolor abdominal y vómitos en las horas posteriores al procedimiento, deben hacer al médico tratante sospechar esta complicación. Presentamos el caso de un paciente joven que luego de someterse a una sesión de litotricia para el tratamiento de una litiasis renal derecha instaló una pancreatitis aguda que requirió ingreso a terapia intensiva y que se suma a los escasos informes de casos publicados en la literatura médica.

Summary: Extracorporeal shock wave lithotripsy to treat urolithiasis is a widely aceptable treatment, although it may involve complications. Acute pancreatitis immediately after the procedures is rather unusual, but it may result in a serious life-threatening complication for patients. The appearance of severe pain and vomits a few hours after the procedure should make physicians suspicious of this complication. The study presents the case of a young patient who developed acute pancreatitis after undergoing lithotripsy to treat lithiasis in the right kidney, requiring his admission to the intensive care unit. This will add up to the scarce reports published in the medical literature.

Resumo: A litotrícia extracorpórea por ondas de choque para o tratamento da urolitíase é um tratamento amplamente aceito, mas não isento de complicações. A pancreatite aguda que se desencadeia imediatamente depois deste procedimento não é frequente, porém pode ser uma complicação grave que ameaça a vida do paciente. O surgimento súbito de dor abdominal e vómitos nas horas seguintes ao procedimento devem induzir à suspeita desta complicação. Apresentamos o caso de um paciente jovem que depois de uma sessão de litotrícia para o tratamento de uma litíase renal direita apresentou uma pancreatite aguda com posterior admissão a terapia intensiva; este caso se agrega aos poucos publicados na literatura médica.

Drenaje endoscópico transgástrico de pseudoquiste pancreático en paciente pediátrico / Transgastric endoscopic drainage of pancreatic pseudocyst in a pediatric patient

Resumen Un pseudoquiste pancreático es una acumulación de líquido casi siempre estéril, rico en enzimas digestivas y jugo pancreático encapsulado en una pared de tejido fibroso y de granulación sin revestimiento epitelial, generalmente de forma ovalada o redondeada. Los pseudoquistes se pueden desarrollar por complicaciones en el páncreas que generan obstrucción o ruptura de un conducto pancreático. Se presenta el caso de un paciente masculino de 9 años con diagnóstico de pseudoquiste pancreático con crecimiento progresivo, debido a trauma abdominal cerrado. Se realizó un manejo multidisciplinario para determinar el tratamiento. Por las características del pseudoquiste, se definió realizar un drenaje endoscópico transgástrico. El procedimiento llevado a cabo es descrito en el presente texto. El paciente evolucionó satisfactoriamente.

Abstract A pancreatic pseudocyst is an accumulation of fluid that is almost always sterile and is rich in digestive enzymes and pancreatic juice that is encapsulated in a wall of fibrous tissue and granulation tissue without an epithelial lining. They are generally oval or rounded. Pseudocysts can develop from complications in the pancreas that lead to obstruction or rupture of a pancreatic duct. We present the case of a 9-year-old male patient diagnosed with a pancreatic pseudocyst with progressive growth due to closed abdominal trauma. Multidisciplinary management determined treatment. Due to the characteristics of the pseudocyst, transgastric endoscopic drainage was used, and the procedure was carried out as described herein. The patient evolved satisfactorily.

Trauma pancreático / Pancreatic trauma

El páncreas es un órgano intraabdominal en posición retroperitoneal, cuyo traumatismo es poco frecuente. La clasificación por grados ha ayudado a la práctica de tratamientos más eficaces y la disminución del número de complicaciones. Estas últimas aparecen como consecuencia del traumatismo o del tratamiento quirúrgico, el cual puede ser simple o implicar grandes resecciones. Se presenta el caso de un paciente sufrió un trauma abdominal cerrado de 3 días de evolución. Se realizaron exámenes diagnósticos y por la clínica y los complementarios se decidió realizar el tratamiento quirúrgico. El objetivo de este trabajo fue exponer los elementos clínicos, resultados de complementarios y hallazgos quirúrgicos en este paciente, así como incentivar la sospecha de esta afección en el traumatismo abdominal(AU)

Pancreas is an intra-abdominal organ in retroperitoneal location chow trauma is uncommon. Degree classification helps in more effective treatment practice and in decrease of complications appeared s consequence of traumas or the surgical treatment, which may be simple or involves large resections. The case of a patient with closed abdominal trauma of 3 days course. Diagnostic and clinic and complementary examinations were carried out being necessary surgical treatment. The aim of present paper was to expose the clinical elements, complementary results and surgical findings in this patient, as well as to motivate the suspicion of this affection in abdominal trauma(AU)

Preservação do baço na pancreatectomia distal por trauma / Distal pancreatectomy with splenic preservation in traumatic injuries of pancreas

OBJETIVOS: A esplenectomia simplifica a pancreatectomia distal no trauma mas tem o inconveniente de aumentar a vulnerabilidade do paciente às infecções. O objetivo é avaliar se a preservação do baço na referida cirurgia é exeqüível e segura. MÉTODOS: A preservação do baço foi feita em 52 pacientes (48 por cento) entre 108 submetidos à pancreatectomia distal. Quarenta e cinco (86,5 por cento) do sexo masculino e sete (13,5 por cento) do sexo feminino. Idade variou de seis a 42 anos com média de 22,1 anos. Trauma penetrante foi a causa da lesão em 35 (67 por cento) com 27 (77 por cento) por arma de fogo e oito (23 por cento) por arma branca. Contusão foi responsável pela lesão em 17 (33 por cento). RESULTADOS: Não houve óbito. Fístula pancreática ocorreu em seis (11,5 por cento) pacientes; coleção subfrênica em seis (11,5 por cento); pancreatite em dois (3,8 por cento); abcesso de parede em quatro (8 por cento); pneumonia em quatro (8 por cento). Quarenta pacientes tiveram lesões associadas. O ISS médio foi de 19,3. O baço apresentava lesão em 13 pacientes. Sete foram submetidos à esplenorrafia e seis à ressecção parcial. Em 51 pacientes o baço foi conservado com os vasos esplênicos. Em um caso foi feita a ligadura proximal e distal dos vasos esplênicos (técnica Warschaw). Permanência hospitalar média de 12 dias. CONCLUSÃO: A pacreatectomia distal com preservação do baço mostrou ser segura nos pacientes estáveis, mesmo na presença de lesões associadas. A ausência de óbitos e a participação de cirurgiões em fase de treinamento confirmam sua segurança.

OBJECTIVES: Splenectomy simplifies distal pancreatectomy in trauma but has the inconvenience of increasing vulnerability to infection. The objective of this study is to assess whether spleen preservation in the aforementioned surgical procedure is feasible and safe. METHODS: Spleen preservation was performed in 52 patients (48 percent) of 108 undergoing distal pancreatectomy. Forty-five (86.5 percent) were males and 7 (13,5 percent) were females. The mean age was 22.1 years, varying from 6 to 42 years. Penetrating trauma was the cause of injury in 35 cases (67 percent), 27 of which (77 percent) due to gunshot wounds and 8 (23 percent) due to stab wounds. Blunt trauma was the cause of injury in 17 cases (33 percent). RESULTS: There were no deaths. Pancreatic leaks occurred in 6 (11.5 percent) patients, fluid collection in the splenic fossa in 6 (11.5 percent), pancreatitis in 2 (3.8 percent), surgical wound abscesses in 4 (8 percent) and pneumonia in 4 (8 percent) patients. Forty patients had associated injuries. The average ISS was 19.3. The spleen was injured in 13 patients. Seven underwent splenorrhaphy and 6 required partial splenic resection. The spleen and splenic vessels were preserved in 51 patients. In one case, proximal and distal ligation of the splenic vessels (Warschaw technique) was performed. Hospital stay averaged 12 days. CONCLUSION: Distal pancreatectomy with spleen preservation was shown to be a safe procedure in stable patients, even with associated injuries. The absence of deaths and the co-participation of surgeons in training confirms the safety of this procedure.
