Análisis de nuestra experiencia en el diagnóstico y tratamiento de la hernia obturatriz en un hospital de tercer nivel / Analysis of our experience in the diagnosis and treatment of obturator hernia in a third level hospital

La patología herniaria supone un porcentaje importante de las intervenciones quirúrgicas urgentes. La hernia obturatriz es una entidad poco frecuente, presentándose generalmente como un cuadro de oclusión intestinal agudo en mujeres adultas. El objetivo del estudio es analizar la experiencia en un hospital de tercer nivel en el diagnóstico y tratamiento de la hernia obturatriz, así como detectar aquellos signos que permitan un diagnóstico precoz. La técnica de imagen de elección para su diagnóstico es la tomografía computarizada. Se trata de un estudio observacional prospectivo, en el que se incluyeron pacientes intervenidos de forma urgente por hernia obturatriz entre los años 2000 y 2016. Para el registro de la morbilidad postoperatoria se empleó la clasificación de Clavien-Dindo. Se identificaron doce pacientes con clínica de obstrucción intestinal secundaria a hernia obturatriz. Todos ellos fueron intervenidos de forma urgente, realizándose laparotomía media urgente en el 59%, laparotomía media infraumbilical en el 33% y abordaje por vía inguinal posterior en un solo paciente (8%). En ocho pacientes (67%) fue necesario realizar una resección intestinal por isquemia intestinal. La técnica quirúrgica empleada fue la reparación mediante malla de polipropileno en seis pacientes (50%), mediante tapón en dos (17%) y cierre con puntos sueltos en cuatro (33%). Cuatro de ellos presentaron complicaciones postoperatorias, registrando un único exitus secundario a perforación por sufrimiento intestinal. Es prioritario establecer un diagnóstico precoz y tratamiento quirúrgico urgente para reducir la morbimortalidad asociada a la hernia obturatriz

Hernia pathology accounts for a large percentage of urgent surgical interventions. Obturator hernia is rare, usually presenting as a picture of acute intestinal occlusion. The aim of the study is to analyze the experience in a third level hospital in the diagnosis and treatment of obturator hernia, as well as to detect those signs that allow an early diagnosis. This is a prospective observational study, which included patients operated on urgently for obturator hernia between 2000 and 2016. For the registration of postoperative morbidity, the Clavien-Dindo classification was used. We identified twelve patients with intestinal obstruction secondary to obturator hernia. All of them were operated on urgently. Urgent midline laparotomy was carried out on 59% of them, infraumbilical laparotomy on 33%, and a posterior inguinal approach was realized on only one patient (8%). In eight patients (67%) it was necessary to perform intestinal resection. Repair was performed by polypropylene mesh in six patients (50%), by plugging in two (17%) and closing with loose stitches in four patients (33%). Four of them presented postoperative complications, recording a single exitus secondary to perforation due to intestinal suffering. Obturator hernia is a rare entity that develops mostly as an occlusive condition in elderly women. The imaging technique of choice for diagnosis is computed tomography. Establishing an early diagnosis and urgent surgical treatment is a priority to reduce associated morbidity and mortality

Síndrome de Boerhaave secundario a vólvulo gástrico / Boerhaave’s syndrome secondary to gastric volvulus

El síndrome de Boerhaave es una ruptura espontánea del esófago, causada por un aumento de presión intraluminal que se produce en el contexto de una presión negativa intratorácica. Tiene un alto índice de morbimortalidad (14-40%), por lo que precisa un diagnóstico y tratamiento precoces. Debería incluirse en el diagnóstico diferencial del dolor epigástrico en un paciente que ha presentado vómitos. Las hernias de hiato paraesofágicas pueden complicarse con una volvulación gástrica. Esta, a su vez, puede producir necrosis tanto esofágica como gástrica que requiere un manejo quirúrgico precoz. Presentamos el caso de un paciente de 83 años que presentó una volvulación gástrica como complicación de una hernia de hiato, con vómitos asociados que desencadenaron un síndrome de Boerhaave. Se trata del segundo caso publicado en la literatura (AU)

Boerhaave’s syndrome is a spontaneous rupture of the oesophagus, caused by an increase of intraluminal pressure that is produced in the context of negative intrathoracic pressure. It has a high index of morbimortality (14-40%), which is why it requires early diagnosis and treatment. When a patient presents vomiting, the differential diagnosis should include epigastric pain. Para-esophageal hiatal hernias can be complicated by gastric volvulus. In its turn, this can produce both oesophageal and gastric necrosis requiring early surgical treatment. We describe the case of an 83-year-old patient who presented gastric volvulus with complications from a hiatal hernia with associated vomiting, which triggered Boerhaave’s syndrome. This is the second case published in the literatura (AU)

[Perforations following endoscopic retrograde cholangiopancreatography (ERCP)]. / Perforaciones post colangiopancreatografía endoscópica retrógrada (CPRE). Manejo quirúrgico.

Endoscopic retrograde cholangiopancreatography (ERCP) associated with sphincterotomy is a useful procedure that is widely used in cases of choledocholithiasis and bile duct obstruction. In spite of being a safe test, there is a risk of complications like pancreatitis, haemorrhaging or perforation. Post-ERCP duodenal perforation is a rare event but has serious consequences if it is not treated early. The lesion mechanism, the place and extension of the perforation, as well as the clinical picture and radiographic findings will guide patient management, which must be individualised and constantly reevaluated. Its mortality is closely related to diagnostic and therapeutic delay. In those cases where a conservative attitude is adopted, close vigilance will be maintained facing the possibility of a worsening of the clinical picture and a change in its management.

[Adult hepatoblastoma. A case report]. / Hepatoblastoma del adulto. Presentación de un caso.

Adult hepatoblastoma is a rare pathology. Its pathogeny is not well understood and prognosis is very bad. We pre-sent a case of adult hepatoblastoma treated in our centre. A 65 year-old male, without previous hepatopathy, who consulted due to right hypochondrial pain with a subacute evolution. The pathological diagnosis was adult epithelial hepatoblastoma, with free surgical margins. The patient recei-ved a second surgical intervention 5 months later due to early recurrence and died 10 months after the diagnosis due to a new massive recurrence. His definitive diagnosis is histological. Radical surgery is the only treatment that increases survival, but recurrence is frequent. There are no well-defined patterns of adjuvant chemotherapy nor is there any trans-plant experience.

Hepatoblastoma del adulto. Presentación de un caso / Adult hepatoblastoma. A case report

El hepatoblastoma del adulto es una patología inusual, de patogenia no bien conocida y de muy mal pronóstico. Presentamos un caso de hepatoblastoma del adulto tratado en nuestro centro. Varón de 65 años, sin hepatopatía previa, que consulta por dolor en hipocondrio derecho de evolución subaguda. El diagnóstico anatomopatológico fue hepatoblastoma epitelial del adulto, con bordes quirúrgicos libres. Fue reintervenido 5 meses después por recidiva precoz y falleció 10 meses después del diagnóstico por nueva recidiva masiva. Su diagnóstico definitivo es histológico. La cirugía radical ofrece el único tratamiento que aumente la supervivencia, pero frecuentemente recidiva. No existen pautas bien definidas de quimioterapia adyuvante, ni experiencia en trasplante (AU)

Methodological advances: using greenhouses to simulate climate change scenarios.

Human activities are increasing atmospheric CO2 concentration and temperature. Related to this global warming, periods of low water availability are also expected to increase. Thus, CO2 concentration, temperature and water availability are three of the main factors related to climate change that potentially may influence crops and ecosystems. In this report, we describe the use of growth chamber - greenhouses (GCG) and temperature gradient greenhouses (TGG) to simulate climate change scenarios and to investigate possible plant responses. In the GCG, CO2 concentration, temperature and water availability are set to act simultaneously, enabling comparison of a current situation with a future one. Other characteristics of the GCG are a relative large space of work, fine control of the relative humidity, plant fertirrigation and the possibility of light supplementation, within the photosynthetic active radiation (PAR) region and/or with ultraviolet-B (UV-B) light. In the TGG, the three above-mentioned factors can act independently or in interaction, enabling more mechanistic studies aimed to elucidate the limiting factor(s) responsible for a given plant response. Examples of experiments, including some aimed to study photosynthetic acclimation, a phenomenon that leads to decreased photosynthetic capacity under long-term exposures to elevated CO2, using GCG and TGG are reported.
