Determinants and impact of splanchnic vein thrombosis in acute pancreatitis.

BACKGROUND: Splanchnic vein thrombosis (SVT) is a well-recognised though little-studied complication in acute pancreatitis (AP). SVT risk factors, its clinical consequences and the role of anticoagulation (AC) therapy is scarce. AIMS: To evaluate the incidence and natural history of SVT in AP. METHODS: Post hoc analysis of a prospective multicentre cohort study involving 23 hospitals in Spain. AP complications were identified by computer tomography, and patients with SVT were re-evaluated after two years. RESULTS: A total of 1655 patients with AP were included. The overall incidence of SVT was 3.6%. SVT was significantly associated with male gender, younger age and alcoholic aetiology. Every local complication increased SVT incidence, and this risk rose gradually with larger extension and infection of necrosis. These patients had a longer hospital stay and underwent a greater number of invasive treatments, regardless of AP severity. Forty-six patients with SVT were followed up. SVT resolution rate was 54.5% in the AC group and 30.8% in the non-AC group with lower thrombotic complications in the SVT resolution group (83.3% vs 22.7%; p<0.001). No AC-related adverse events occurred. CONCLUSION: This study identifies the risk factors and negative clinical impact of SVT in AP. Our results justify future trials to demonstrate the role of AC in this clinical scenario.

Factors associated with mortality in patients with infected pancreatic necrosis: the "surgery effect".

Severe acute pancreatitis complicated by infection is associated with high mortality. Invasive treatment is indicated in the presence of infected (suspected) pancreatic and/or peripancreatic necrosis (IPN) in the absence of response to intensive medical support. Step-up approach (SUA) has been demonstrated to lower complication rate compared to upfront open surgery. However, this approach has not been associated with lower mortality, and no factors have been studied that could help to identify the high risk patients. In this study, we aimed to analyse those factors associated with mortality following the invasive treatment of IPN, focusing on the role of surgical necrosectomy. A retrospective and observational study based on a multicentre prospective database was conducted. The database was coordinated by the Hospital General Universitario de Alicante, Spain and the Spanish Association of Pancreatology. Demographics, clinical data, and laboratory and imaging findings were collected. Atlanta 2012 criteria were considered to classify acute necrotizing pancreatitis and for the definition of IPN. Step-up approach was used in all centres with the intention of avoiding surgery whenever possible. Surgical necrosectomy was performed by open approach. From January 2013 to October 2014, a total of 1655 patients with the diagnosis of acute pancreatitis were included in our database. 1081 were recruited for the final analysis. Out of them, 205 (19%) were classified into acute necrotizing pancreatitis. 77 (8.3%) patients underwent invasive treatment of INP and were included in our study. Overall mortality was 29.9%. Upfront endoscopic or percutaneous drainage was performed in 60 (77.9%) patients and mortality was 26.6%. Out of 60, 22 (36.6%) patients subsequently received rescue surgery; mortality in rescue surgery group was 18.3%. Upfront surgery was carried out in 17 (22.1%) patients; mortality in this group was 41%. At univariate analysis, surgical necrosectomy, extrapancreatic infection, immunosuppression and de-novo haemodialysis were associated with mortality. At multivariate analysis, only surgical necrosectomy was significantly associated with mortality (p = 0.002 OR 3.89). Surgical approach for IPN is associated with high mortality rate. However, these data should be interpreted with caution, since we are not able to assess whether this occurs due to the need of surgery as the only resort when the other approaches are not feasible or fail.

El sobrecrecimiento bacteriano de intestino delgado es una entidad frecuente tras gastrectomía, pero con escasa relevancia en el estado nutricional / Small intestinal bacterial overgrowth is common after gastrectomy but with little impact on nutritional status

Antecedentes: La evidencia disponible que evalúa el impacto de la presencia de sobrecrecimiento bacteriano de intestino delgado (SIBO) después de una gastrectomía es escasa. Objetivos: Evaluar la frecuencia de SIBO tras gastrectomía y su asociación con malnutrición. Describir las líneas antibióticas necesarias para su corrección y si mejora el estado nutricional. Material y métodos: Estudio de cohortes prospectivo en el ámbito de la Agencia Sanitaria Costa del Sol desde 2012 hasta 2015. Se realizó test del aliento en hidrógeno y en metano espirado con sobrecarga oral de glucosa. Recogida de variables demográficas y valoración nutricional, basal y al mes del tratamiento eficaz del SIBO. Se evaluaron las pautas antibióticas y el número de tratamientos. Resultados: Se analizaron 60 pacientes gastrectomizados, 58,3%varones. Se realizó un subanálisis de la curva a los 45min para minimizar los posibles falsos positivos con una frecuencia de SIBO del 61,6%. En presencia de SIBO, se observó una tendencia no significativa a presentar un menor IMC. Tras el tratamiento con rifaximina, el SIBO permaneció positivo en el 94,6% y tras metronidazol, en el 85,7%. El multifracaso de la terapia antibiótica fue de 67,6%. No hay cambios estadísticamente significativos en parámetros nutricionales después del tratamiento. Conclusiones: El SIBO está presente en el 61,6% de los pacientes gastrectomizados, sin que se demuestre asociación con el deterioro nutricional. Rifaximina y metronidazol son escasamente efectivos en la erradicación del SIBO. Cuando este se consigue, el efecto sobre la malnutrición es escaso, pudiendo correlacionarse con otros factores

Background: Available evidence assessing the impact of small intestinal bacterial overgrowth (SIBO) following gastrectomy is limited. Objectives: To evaluate the prevalence of SIBO after gastrectomy and its association with malnutrition. To describe the antibiotic treatment required to correct it and if nutritional status improves. Material and methods: A prospective cohort study was performed at the Agencia Sanitaria Costa del Sol (Costa del Sol Health Agency) from 2012 to 2015. A hydrogen-methane breath test with oral glucose overload was performed. Demographic variables and nutritional parameters were collected at baseline and one month after effective treatment of SIBO. The antibiotic regimens and the number of treatment lines used were assessed. Results: Sixty gastrectomy patients were analysed, 58.3% of which were male. A sub-analysis of the curve was performed at 45min to minimise possible false positives, and SIBO was identified in 61.6% of cases. SIBO patients tended to have a lower BMI, although this trend was not statistically significant. After treatment with rifaximin, 94.6% of patients were still positive for SIBO, which fell to 85.7% after metronidazole. The rate of total antibiotic treatment failure was 67.6%. No statistically significant changes were found in nutritional parameters after treatment. Conclusions: SIBO was identified in 61.6% of patients after gastrectomy. No correlation was found with any malnutrition parameter. Rifaximin and metronidazole were found to be largely ineffective in eradicating SIBO. When treatment was effective, the impact on malnutrition was negligible and may have been associated with other factors

Determinants of Severity in Acute Pancreatitis: A Nation-wide Multicenter Prospective Cohort Study.

OBJECTIVE: The aim of this study was to compare and validate the different classifications of severity in acute pancreatitis (AP) and to investigate which characteristics of the disease are associated with worse outcomes. SUMMARY OF BACKGROUND DATA: AP is a heterogeneous disease, ranging from uneventful cases to patients with considerable morbidity and high mortality rates. Severity classifications based on legitimate determinants of severity are important to correctly describe the course of disease. METHODS: A prospective multicenter cohort study involving patients with AP from 23 hospitals in Spain. The Atlanta Classification (AC), Revised Atlanta Classification (RAC), and Determinant-based Classification (DBC) were compared. Binary logistic multivariate analysis was performed to investigate independent determinants of severity. RESULTS: A total of 1655 patients were included; 70 patients (4.2%) died. RAC and DBC were equally superior to AC for describing the clinical course of AP. Although any kind of organ failure was associated with increased morbidity and mortality, persistent organ failure (POF) was the most significant determinant of severity. All local complications were associated with worse outcomes. Infected pancreatic necrosis correlated with high morbidity, but in the presence of POF, it was not associated to higher mortality when compared with sterile necrotizing pancreatitis. Exacerbation of previous comorbidity was associated with increased morbidity and mortality. CONCLUSION: The RAC and DBC both signify an advance in the description and differentiation of AP patients. Herein, we describe the complications of the disease independently associated to morbidity and mortality. Our findings are valuable not only when designing future studies on AP but also for the improvement of current classifications.

Soporte nutricional en el paciente con cirrosis hepática / Nutritional support in patients with liver cirrhosis

Dadas las múltiples funciones sintéticas, reguladoras y destoxificadoras del hígado, cuando la disfunción hepatocelular es importante una de las características que la acompaña es la presencia de malnutrición. La malnutrición es muy frecuente en la cirrosis hepática, incluso en fases relativamente tempranas de la enfermedad. Independientemente de la etiología de la cirrosis, un pobre estado nutricional se asocia a un mal pronóstico, por tanto, una intervención precoz en la reposición del déficit de nutrientes puede prolongar la esperanza de vida, mejorar la calidad de vida, disminuir las complicaciones y preparar al paciente para un trasplante más exitoso. En el presente trabajo se revisan los conocimientos actuales en el diagnóstico y manejo de la malnutrición en pacientes cirróticos. Prestamos especial atención al concepto de colación después de la cena (late evening snack) y analizamos las características, composición y probables beneficios en el curso de la enfermedad (AU)

Given the liver’s multiple synthetic, regulatory and detoxifying functions, one of the characteristics accompanying severe hepatocellular dysfunction is the presence of malnutrition. This disorder is highly frequent in liver cirrhosis, even in the relatively early stages of the disease. Independently of the cause of the cirrhosis, poor nutritional status is associated with a worse prognosis and therefore early intervention to correct nutrient deficiency can prolonglife expectancy, improve quality of life, reduce complications and increase the probability of successful transplantation. The present article reviews current knowledge of the diagnosis and management of malnutrition in patients with cirrhosis. Special attention is paid to the concept of the late evening snack and its characteristics, composition and probable benefits in the course of the disease (AU)

Metástasis pancreática única de carcinoma renal / Solitary pancreatic metastasis from renal carcinoma

Presentamos el caso de un varón de 60 años, con antecedentes de nefrectomía radical izquierda por carcinoma renal, en grado nuclear II de Fuhrman, 8 años atrás. Por traumatismo abdominal cerrado se solicitó una TC abdominal en la que se observó una lesión sólida, hipervascular en la cabeza pancreática de 4cm de diámetro. Con la sospecha diagnóstica de metástasis pancreática de carcinoma renal se realizó duodenopancreatectomía cefálica con preservación pilórica. El estudio anatomopatológico confirmó la presunción diagnóstica. A los 23 meses de seguimiento el paciente está libre de enfermedad (AU)

We present the case of a 60-year-old man with a history of left radical nephrectomy due to Fuhrman nuclear grade II renal carcinoma 8 years previously. Abdominal computed tomography was performed due to a closed abdominal injury, revealing a solid, 4-cm hypervascular mass in the head of the pancreas. The suspected diagnosis was pancreatic metastasis from renal carcinoma. Cephalic duodenopancreatectomy was performed. The diagnosis was confirmed by histopathological analysis. At 23 months of follow-up, the patient remains disease free (AU)

Causa poco frecuente de úlcera gástrica / A rare cause of gastric ulcer

Las lesiones del tracto gastrointestinal inducidas por fármacos son cada vez más frecuentes, pero en general poco reconocidas. Aunque hay un número elevado de fármacos que se asocian con efectos adversos gastrointestinales, hay limitados patrones característicos de los mismos. La gastritis aguda isquémica es una entidad poco común que rara vez se distingue de otras formas de isquemia intestinal. Presentamos el caso de una mujer de 69 años que en el contexto de una reagudización de su anemia, encontramos una lesión gástrica poco común (AU)

Drug-induced gastrointestinal tract lesions are becoming more frequent but are generally little known. Although a large number of drugs have gastrointestinal adverse effects, there are few characteristic patterns. Acute ischemic gastritis is an uncommon entity that is rarely distinguished from other forms of intestinal ischemia. We report the case of a 69-year-old woman who was diagnosed with an unusual gastric lesion in the context of an acute exacerbation of her anemia (AU)

[Primary esophageal melanoma]. / Melanoma esofagico primario.

Primary Esophageal Melanoma (PEM) is an extremely rare neoplasm, with less than 270 cases described. Although clinical presentation is similar to any other esophageal neoplasm, MEP's behavior is more aggressive and fatal in most cases. We report two new cases of MEP diagnosed through endoscopy and anatomical-pathological analysis of collected biopsies. Both samples were positive for HMB-45 and S100, so the presence of primary melanoma in other location was ruled out. The form of presentation as left miosis with no eyelid ptosis or enophthalmos should be highlighted in the first case, which was described by this early manifestation. Unfortunately, the neoplasm could not be excised when diagnosed because the thoracic artery was found to be affected through echoendoscopy. In the second case, in spite of the fact that the neoplastic extension was only local, and neoplasm was subject to transhiatal esophagectomy, the patient had multiple post-surgical complications and died nineteen days after the surgical procedure. Furthermore, bibliographic review is applied to diagnosis, treatment options, and prognosis of this exceptional neoplasm.

Melanoma esofágico primario / Primary esophageal melanoma

El melanoma esofágico primario (MEP) es una neoplasia extremadamente rara, con menos de 270 casos descritos. Aunque la presentación clínica es similar a cualquier otra neoplasia esofágica, su comportamiento es más agresivo y fatal en la mayoría de los casos. Presentamos dos nuevos casos de MEP diagnosticados mediante endoscopia y estudio anatomopatológico de las biopsias obtenidas, siendo en ambos casos las muestras positivas para HMB-45 y S100, descartando así mismo la presencia de melanoma primario en otra localización. En el primer caso merece destacar la forma de presentación como miosis izquierda sin ptosis palpebral ni enoftalmos, siendo el primer caso descrito con esta manifestación inicial, lamentablemente al momento del diagnóstico fue irresecable, demostrando así mismo por ecoendoscopia afectación de la aorta torácica. El segundo caso a pesar de ser una neoplasia sin extensión locorregional y sometido a esofaguectomía transhiatal presentó múltiples complicaciones postoperatorias falleciendo al decimo noveno día de la intervención. Así mismo se hace una revisión bibliográfica sobre diagnóstico, opciones de tratamiento y pronóstico de esta excepcional neoplasia.

[Incidence and clinico-epidemiological aspects of ulcerative colitis in the area of the Hospital Costa del Sol]. / Incidencia y aspectos clinicoepidemiológicos de la colitis ulcerosa en el área de influencia del Hospital Costa del Sol.

INTRODUCTION: The incidence of inflammatory bowel disease, and of ulcerative colitis in particular, varies widely according to geographical area and has been reported to have increased in the last few years, although some of the differences observed may be due to the methodology employed. OBJECTIVES: To determine the incidence of ulcerative colitis in our area and to compare it with that described in other areas of Spain and Europe, as well as to describe certain clinico-epidemiological aspects of this disease. MATERIAL AND METHODS: A descriptive, prospective, population-based study was performed from 2000-2001 in patients diagnosed with ulcerative colitis in the catchment area of the Hospital Costa del Sol, with a population of 210,384 inhabitants. The crude incidence rate was adjusted by the direct method, using the European standard population (EU-25, 2000) as the reference population; 95% confidence intervals were calculated. RESULTS: Forty-three patients (23 men [53.5%] and 20 women [46.5%], with a mean age of 35.23 years [SD=15.42]) were included. Thirty-three percent were residents of the Hospital Costa del Sol's catchment area and were included in the calculation of incidence. The crude incidence was 7.84 and the incidence adjusted by age and sex to the European population was 7.26 per 100,000 inhabitants/year. CONCLUSIONS: The incidence of ulcerative colitis in the area of the Hospital Costa del Sol is higher than that found in other studies performed in the autonomous community of Andalusia as well as that observed in some studies performed in the north of the Peninsula.

[Distinct clinical presentations of a single medical entity: eosinophilic enteritis]. / Diferentes formas de presentación de una misma entidad clínica: gastroenteritis eosinofílica.

Eosinophilic enteritis is a rare disease characterized by eosinophilic infiltration of different wall layers of the gastrointestinal tract, from the esophagus to the rectum, by eosinophilic cells. The most frequently affected structures are the stomach and small intestine. The pathogenesis of eosinophilic enteritis is not well understood and is often related to a personal or familial history of atopy. Clinical symptoms depend on the affected layers. Thus malabsorptive syndrome, intestinal strictures or ascites depend on a mucosal, muscular or serosa layer infiltration, respectively. We present three cases of eosinophilic gastroenteritis with distinct clinical presentations.

Diferentes formas de presentación de una misma entidad clínica: gastroenteritis eosinofílica / Distinct clinical presentations of a single medical entity: eosinophilic enteritis

La enteritis eosinofílica es una rara enfermedad caracterizada por la infiltración de cualquier tramo del tracto gastrointestinal, desde el esófago hasta el recto, por células eosinófilas, aunque el estómago y el intestino delgado son las estructuras más frecuentemente afectadas. Su etiopatogenia se desconoce, y en muchas ocasiones se relaciona con antecedentes personales o familiares de atopia. Las manifestaciones clínicas varían en función de las capas afectadas; así, la presentación como síndrome de malabsorción digestiva, estenosis intestinal o ascitis dependerá de si la eosinofilia predomina en la mucosa, muscular o serosa, respectivamente. Se presentan 3 casos clínicos con diferentes formas de presentación de gastroenteritis eosinofílica
