Hemorragia digestiva alta como forma de presentación de hematoma retroperitoneal espontáneo gigante secundario a anticoagulación en una mujer con reordenación del gen JAK2 / Spontaneous retroperitoneal hematoma in a patient under anticoagulant agents presenting as upper gastrointestinal bleeding

Presentamos el caso de una mujer de 44 años de edad con antecedentes de abortos de repetición y síndrome de Budd-Chiari secundario a una mielofibrosis primaria en tratamiento anticoagulante. Consulta por melenas y astenia, presentando anemización progresiva. En una gastroscopia inicial se aprecia una compresión extrínseca a nivel supraampular de segunda porción duodenal, con una úlcera asociada en cara posterior de bulbo y primera rodilla. Posteriormente se diagnostica mediante una tomografía computarizada de un hematoma retroperitoneal espontáneo secundario a anticoagulación. Se trata con drenaje percutáneo y retirada de anticoagulación con buena respuesta inicial. No obstante, presenta complicaciones trombóticas (trombosis subclavia y yugular) y se reintroducen los anticoagulantes con dosis en el límite bajo del rango terapéutico (AU)

We present the case of a 44-year-old woman with past history of repeated miscarriage and Budd-Chiari syndrome secondary to primary myelofibrosis. Because of this she was under treatment with oral anticoagulant agents. The patient was admitted in hospital as she presented with gastrointestinal bleeding (melena), asthenia and progressive anemia. In an initial upper endoscopy an extrinsic duodenal compression associated with an ulcer on the posterior face of the first portion of duodenum and upper duodenal knee was observed. In the following days a huge spontaneous retroperitoneal hematoma due to anticoagulation was diagnosed by computed tomography. This was treated with a percutaneous drainage and withdrawal of the antithrombotic drugs. The evolution of the patient was initially satisfactory but she suffered subclavian and jugular vein thrombosis, and reintroduction of anticoagulant agents at the lowest therapeutic doses was required (AU)

Utilidad de la 18-fluorodeoxiglucosa en la tomografía por emisión de positrones-tomografía computarizada (PET-TC) preoperatoria en el diagnóstico precoz del cáncer de páncreas exocrino: estudio en 139 casos resecados / Utility of 18 fludeoxyglucose in preoperative positon-emission tomography-computed tomography (PET-CT) in the early diagnosis of exocrine pancreatic cancer: A study of 139 resected cases

INTRODUCCIÓN: El único tratamiento curativo del cáncer de páncreas (CP) es la exéresis quirúrgica, pero debido a su presentación clínica tardía solo el 15-25% de los pacientes son candidatos a resección curativa. El objetivo de este trabajo, prospectivo y unicéntrico, es determinar la utilidad de la PET-TC preoperatoria en el diagnóstico precoz del CP, en su estadificación y en la detección de estadios precursores de la enfermedad en una serie de 139 pacientes sometidos a intervención quirúrgica con «intención curativa» y con el diagnóstico histológico de adenocarcinoma ductal. MÉTODOS: Hemos estudiado las características histopatológicas del CP y de las diferentes lesiones panIN en las piezas quirúrgicas de 139 pacientes sometidos a resección pancreática durante el periodo 2010-2014, comparando estos resultados con los datos preoperatorios de una tomografía computarizada multidetector con contraste trifásico (TCMD) y una PET-TC en la que la captación de glucosa fue determinada por el SUV, considerando malignidad por encima de 2,5. RESULTADOS: En nuestra serie, la sensibilidad de la PET-TC para el diagnóstico tumoral fue del 77,7% (108 de los 139 casos) versus el 75,5% (105 de los 139 casos) para la TCMD. Cuando combinamos este valor máximo del SUV tumoral con el SUV máximo de tejido pancreático normal de cada paciente, la sensibilidad diagnóstica de la PET-TC para el CP asciende al 94,9% (132 de los 139 casos). CONCLUSIÓN: Una combinación de los estudios del PET-TC en el tejido tumoral y no tumoral de cada paciente puede ser una herramienta diagnóstica muy útil no solo para el diagnóstico preoperatorio del CP, sino también para las lesiones panIN

INTRODUCTION: In pancreatic ductal adenocarcinoma (PDA), surgical resection is the only curative treatment, but due to its late clinical presentation only 15-25% patients are candidates for curative resection. The aim of this prospective, single-center study is to determine the diagnostic utility of preoperative PET-CT for early detection of PDA and early panIN lesions. METHODS: We studied the histopathological features of PDA and different panIN lesions in 139 surgical samples from patients undergoing pancreatic resection (from 2010-2014), comparing these results with preoperative PET-CT and MDCT study. For tumor diagnosis in PET-CT maximum standard SUV 2.5 was used. Pancreatic baseline SUVmax is the maximum uptake of the radiotracer 18-2FDG on the ROI curve determined for the area of the normal pancreas after pathological reassessment with areas not affected by tumours or preneoplastic lesions. Tumour Uptake Index is the ratio between the tumour SUVmax and pancreatic baseline SUVmax. RESULTS: Using an standard maximum SUV value of 2.5, PET-CT sensitivity was 77.7% (108 of the 139 cases) against 75.5% (105 of the 139 cases) of MDCT. But when we combined this value with maximum SUV of normal pancreatic tissue from each patient, PET-CT sensitivity improved its value to 94.9%. CONCLUSION: A combination of studies of PET-CT in tumor and non-tumor tissue of each patient might be a very useful diagnostic tool not only for preoperative diagnosis of PDA, but also for early panIN lesions

Factores pronósticos de los tumores neuroendocrinos de páncreas resecados. Experiencia en 95 pacientes / Prognostic factors in resected pancreatic neuroendocrine tumours: Experience in 95 patients

INTRODUCCIÓN: El objetivo de este estudio fue analizar los factores pronósticos que influyen en la supervivencia y en la recidiva en una serie de pacientes diagnosticados de tumores neuroendocrinos de páncreas (TNEP) y tratados mediante resección quirúrgica. MÉTODOS: Serie retrospectiva de 95 pacientes intervenidos y resecados de TNEP. Las variables estudiadas son: edad, sexo, forma de presentación (esporádica/familiar), funcionalidad, tipo de tumor, localización, cirugía realizada, tamaño tumoral, multifocalidad, tasa de curación y de recidiva. Se ha utilizado la nueva clasificación de la OMS en 2010. RESULTADOS: De los 95 pacientes, 45 eran varones y 50 mujeres, con una edad media de 47,6 años. Presentación esporádica en 66 pacientes (69,8%) y familiar en los 29 restantes (30,2%), asociados a síndrome MEN 1. El 59% (56 pacientes) eran no funcionantes y el 41% restante funcionantes. Los TNEP funcionantes incluían 20 insulinomas, 16 gastrinomas y 3 glucagonomas. La técnica quirúrgica más utilizada (42 pacientes) fue la pancreatectomía corporocaudal. Según la clasificación de la OMS (2010), 59 pacientes presentaban un TNEP G1, 24 un TNEP G2 y los 12 pacientes restantes un carcinoma pobremente diferenciado. La supervivencia a los 5 años en los tumores bien diferenciados ha sido del 100%, independientemente de la funcionalidad. Los TNE esporádicos suelen ser unifocales (p < 0,001) y se asocian a metástasis hepáticas. El seguimiento medio ha sido de 85,3 meses, con una tasa de supervivencia del 65,8% y de recidiva del 24%. CONCLUSIONES: En nuestra experiencia, la clasificación de la OMS (2010) es un factor pronóstico independiente en la supervivencia de los TNEP

INTRODUCTION: The aim of this study was to analyze prognostic factors for survival and recurrence in patients with resected pancreatic neuroendocrine tumors (PNT). METHODS: Medical records of 95 patients with resected PNT were retrospectively reviewed. The variables studied were: age, sex, form of presentation (sporadic/familial tumors), functionality, type of tumor, localization, type of surgery, tumor size, multifocal tumors and recurrent rate. The new WHO classification (2010) was used. RESULTS: There were 45 men and 50 women. Mean age was 46.8 years. Regarding the mode of presentation, it was sporadic in 66 patients (69.8%) and 29 cases were familial neuroendocrine tumors (30.2%) in association with MEN 1 syndrome. The 59% of patients suffered from non-functional tumors and 41% were functional: 20 insulinoma, 16 gastrinoma, and 3 glucagonoma. Distal pancreatectomy was the most common surgical procedure, followed by tumor enucleation in 19 patients. According to the WHO classification, 59 patients had a PNT G1, 24 PNT G2 and 12 with a poorly-differentiated carcinoma, respectively. The 5-year survival in well-differentiated tumors was 100%, regardless of the functionality. Sporadic PNT are more commonly unifocal (P<0.001), associating liver metastasis. Survival and recurrence rates after a mean follow-up of 85.3 months were 65.8 and 24%, respectively. CONCLUSIONS: In our experience, WHO classification was an independent prognostic factor in PNT survival

Pancreatitis del surco versus adenocarcinoma de páncreas: a propósito de 8 casos / Groove pancreatitis vs. pancreatic adenocarcinoma: A review of 8 cases

INTRODUCCIÓN: La pancreatitis del surco (PS) es una entidad poco frecuente que clínica y radiológicamente puede simular un carcinoma del área periampular. El objetivo de este trabajo es presentar una serie de 8 pacientes que fueron intervenidos quirúrgicamente con el diagnóstico preoperatorio de masa en cabeza pancreática, con un diagnóstico anatomopatológico definitivo de PS. Metodos: En nuestra serie, 6 eran hombres y 2 mujeres y tenían una edad media de 51,9 años. Previamente a la cirugía, todos los pacientes presentaban dolor abdominal en epigastrio que requería analgesia a altas dosis. En la analítica preoperatoria, el CEA y el Ca 19.9 fueron normales en todos los pacientes. Los estudios de imagen mostraron lesiones sólidas intrapancreáticas en 6 de los 8 pacientes, y en los 2 restantes una masa mamelonada de 5 y 6 cm, respectivamente, que estenosaba la luz duodenal. La ecoendoscopia fue negativa para células neoplásicas en todos los pacientes. RESULTADOS: La evolución durante el postoperatorio inmediato fue satisfactoria, sin complicaciones. En nuestra serie, no ha fallecido ningún paciente. La evolución a largo plazo, en 7 de los 8 pacientes, ha sido excelente, con desaparición del dolor abdominal y mejoría del estado nutricional. El caso restante ha tenido frecuentes episodios de pancreatitis aguda recidivante y, a los 60 meses, ha presentado un seudoquiste que ha precisado una quistoyeyunostomía en Y de Roux. CONCLUSIONES: La PS debe incluirse en el diagnóstico diferencial de lesiones pancreáticas, que pueden incluir carcinoma del área periampular y otras causas de pancreatitis crónica

INTRODUCTION: Groove pancreatitis (PS) is an uncommon clinical situation and radiologically it can mimic carcinoma of the periampullary area. The aim of this paper is to study a series of 8 patients who underwent surgery with preoperative diagnosis of pancreatic head mass and subsequent pathological diagnosis of PS. METHODS: In our series, 6 were men and 2 women, with an average age of 51,9 years. Before surgery, all patients had epigastric abdominal pain requiring analgesia at high doses. The preoperative analytical CEA and Ca 19.9 were normal in all patients. Imaging studies showed intrapancreatic solid lesions in 6 of the 8 patients, and in the remaining 2 one papillary mass of 5 and 6 cm, respectively, that caused stenosis in the duodenal luz. EUS neoplastic cells were negative in all patients. RESULTS: The immediate postoperative evolution was satisfactory, there are no complications. In our series, no patients have died. The long-term follow-up, in 7 of the 8 patients, has been excellent with disappearance of abdominal pain and improvement of nutritional status. The remaining patient had frequent recurrent episodes of acute pancreatitis, and at 60 months, presented a pseudocyst that has required a Roux-en-Y cystojejunostomy. CONCLUSIONS: PS must be included in the differential diagnosis of pancreatic lesions, which may include carcinoma of the periampullary area and other causes of chronic pancreatitis

Spontaneous retroperitoneal hematoma in a patient under anticoagulant agents presenting as upper gastrointestinal bleeding.

We present the case of a 44-year-old woman with past history of repeated miscarriage and Budd-Chiari syndrome secondary to primary myelofibrosis. Because of this she was under treatment with oral anticoagulant agents. The patient was admitted in hospital as she presented with gastrointestinal bleeding (melena), asthenia and progressive anemia. In an initial upper endoscopy an extrinsic duodenal compression associated with an ulcer on the posterior face of the first portion of duodenum and upper duodenal knee was observed. In the following days a huge spontaneous retroperitoneal hematoma due to anticoagulation was diagnosed by computed tomography. This was treated with a percutaneous drainage and withdrawal of the antithrombotic drugs. The evolution of the patient was initially satisfactory but she suffered subclavian and jugular vein thrombosis, and reintroduction of anticoagulant agents at the lowest therapeutic doses was required.

Una nueva técnica quirúrgica para la hepatectomía derecha extendida: torniquete en la cisura umbilical y oclusión portal derecha (ALTPS). Caso clínico / A new surgical technique for extended right hepatectomy: Tourniquet in the umbilical fissure and right portal vein occlusion (ALTPS). Clinical case

Associating liver partition and portal vein ligation for staged (ALPPS) para las resecciones hepáticas en 2 tiempos, consigue la hipertrofia del volumen funcional residual (VFR) en 7 días, al ocluir las colaterales intrahepáticas entre ambos lóbulos. En marzo de 2012 publicamos una nueva técnica quirúrgica, asociando la colocación de un torniquete en la línea de Cantlie con ligadura portal derecha (Associating liver tourniquet and right portal vein occlusion for staging hepatectomy [ALTPS]). Ahora presentamos la técnica ALTPS en la cisura umbilical para hipertrofiar los segmentos II - III , realizada en un varón de 51 años con recidiva de hipernefroma renal derecho que invade todo el lóbulo derecho y la vena cava inferior. El VFR preoperatorio fue de 380 ml (20% del total) y aumentó un 150% a los 7 días (a 953 ml; 31% del total). En el segundo tiempo se realizó trisectorectomía derecha con resección de la vena cava inferior retrohepática, siendo sustituida por un injerto de goretex anillado de 2 cm de diámetro (AU)

ALPPS (associating liver partition and portal vein ligation for staged hepatectomy), in 2-stage liver resections, achieves hypertrophy of the functional liver remnant (FLR) in 7 days, and the objective of this technique is the occlusion of the intrahepatic collaterals. In March 2012 we published a new surgical technique associating the insertion of a tourniquet in Cantlie’ line and right portal vein ligation (ALTPS: Associating liver tourniquet and right portal vein occlusion for staged hepatectomy). In this paper we present this ALTPS technique placing the tourniquet in the umbilical fissure to obtain hypertrophy of segments II - III . It was performed in a 51 year-old patient with a recurrent right renal hypernephroma which involved all the anatomic right lobe and inferior vena cava. Preoperative FLR was 380 ml (20% of the total volume) increasing 150% at 7 days (to 953 ml, 31% of the total). In the second step, we performed a right trisectionectomy and retrohepatic inferior vena cava resection, replacing it by a 2 cm-ring goretex graft (AU)

Una nueva estrategia quirúrgica para metástasis hepáticas bilobares múltiples: oclusión portal derecha y torniquete en la línea de sección parenquimatosa / A new surgical strategy for multiple multiple bilobular liver metastases: right portal occlusion and torniquet in the parenchyma section line

Recientemente, han publicado la oclusión portal derecha más split in situ como un nuevo método para hipertrofiar en 7 días el volumen residual (VR) tras las resecciones hepáticas en dos tiempos. Es una técnica compleja, fundamentada en ocluir las colaterales intrahepáticas entre ambos lóbulos. Presentamos una técnica original para hipertrofiar el VR ocluyendo la vena porta derecha y las colaterales intrahepáticas: mujer de 35 años con un tumor estromal intestinal y 14 metástasis bilobares, siendo el VR estimado del 24%. Una vez extirpadas las lesiones del lóbulo izquierdo, ocluimos la porta derecha y aplicamos un torniquete en la línea de Cantlie mediante maniobra de hanging. Al 7.° día hipertrofió el VR un 57% y al 8.° día se realizó una hepatectomía derecha. Nuestra técnica es eficaz y sencilla de realizar y, de corroborarse en futuros estudios, esta técnica sería de elección en las resecciones hepáticas en 2 tiempos (AU)

Right portal vein occlusion plus «in situ split» has recently been reported as a new method to hypertrophy the functional remnant volume (FRV) in 7 days after two-stage liver resection. It is a complex procedure associated with the occlusion of the intrahepatic collaterals between both lobes. We present an original technique for hypertrophying the FRV by occluding the right portal vein and the intrahepatic collaterals: a case is presented of a 35-year-old woman with an intestinal stromal tumour, 14 bilobar metastases and an estimated 24% FRV. Once the lesions were removed from the left lobe, we performed a right portal vein transection and applied a tourniquet on the Cantlie line, using the hanging manoeuvre. A 57% hypertrophy of the FRV was achieved by day 7, and the right hepatectomy was performed on day 8. Our technique is effective and simple to perform and if corroborated in future studies, this technique would be of choice in 2-stage liver resection (AU)

A retrospective study comparing 2 series of cases in different (1997-1984 vs. 2001-2008)

Introducción Presentamos una serie de 146 casos de traumatismos hepáticos (TH) atendidos en nuestro hospital en un periodo de 8 años (2001-2008), comparándola con una serie previa de 92 casos (1977-1984).Material y método En la serie actual, la edad media fue de 29,6 años, predominando los hombres. Los traumatismos cerrados predominan sobre los penetrantes, siendo la causa más frecuente los accidentes de tráfico. Resultados Para valorar el grado de lesión hepática utilizamos la clasificación de la American Association for the Surgery of Trauma (AAST). El 79,5% de los enfermos presentaron lesiones asociadas abdominales y/o extraabdominales, siendo las más frecuentes los traumatismo torácicos vs. las fracturas óseas en la serie anterior. La lesión intraabdominal asociada más frecuente fue la esplénica en ambas series. La técnica diagnóstica más utilizada, en la serie actual, fue TAC abdominal. En la serie anterior, las exploraciones más utilizadas fueron la punción simple y la punción-lavado peritoneal (PLP). En 98 casos se llevó a cabo un tratamiento no operatorio y en 48 restantes se indicó cirugía. En la serie previa, se intervino al 97,8% de los pacientes. En la serie actual, en los 15 pacientes con lesiones hepáticas severas se realizaron 5 hepatectomías derechas, 2 segmentectomías, 6 packing de compresas y los 2 restantes fueron exitus intraoperatorios por avulsión hepática. La mortalidad global fue del 3,4%, siendo del 1% en el grupo TNO y del 8,3% en los pacientes intervenidos. En la serie previa, la mortalidad global fue del 29,3%.ConclusionesEl factor esencial para utilizar el tratamiento no operatorio (TNO) es controlar la estabilidad hemodinámica del paciente dejando el tratamiento quirúrgico a los pacientes hemodinámicamente inestables (AU)

Introduction: We present a series of 146 cases of hepatic trauma (HT) treated in our hospital over a period of 8 yearsm (2001-2008), and comparing it with a previous series of 92 cases(1977-1984).Material and method: The mean age in the current series was 28.6 years and the majority were male. The closed traumas were mainly penetrating, with the most frequent cause being road traffic accidents. Results: The American Association for the Surgery of Trauma (AAST) classification was used to evaluate the grade of the hepatic injury. Associated abdominal and /or extra-abdominal injuries were seen in 79.5% of the patients, with the most frequent being chest trauma, compared to bone fractures in the previous series. The most common associated intraabdominalinjury was the spleen in both series. The most used diagnostic technique in the current series was abdominal CT. Simple peritoneal puncture and lavage (PLP) were the most used examinations used in the previous series. Non-surgical treatment (NST) was given in 98 cases and the surgery was indicated in the remaining 48. In the previous series,97.8% of patients were operated on. In the current series, on the 15 patients with severe liverinjuries, 5 right hepatectomies, 2 segmentectomies and 6 packing compressions were performed, with the remaining two dying during surgery due to hepatic avulsion. The overall mortality was 3.4%, being 1% in the NST group and 8.3% in the surgical patients. In the previous series, the overall mortality was 29.3%.Conclusions: The key factor for using NST is to control haemodynamic stability, leavingsurgical treatment for haemodynamically unstable patients (AU)
