Management of perianal fistula in inflammatory bowel disease: identification of prognostic factors associated with surgery.

PURPOSE: As one of the clinical manifestations of inflammatory bowel disease (IBD), perianal fistula disease (PFD) can potentially impact the patient quality of life. The management of PFD employs a multidisciplinary approach which includes antibiotics, biological therapies, immunomodulators, and surgery. We analyzed the outcome and prognostic factors of anal fistula surgery in IBD patients. METHODS: We conducted a retrospective study of IBD patients undergoing elective surgery for anal fistula between January 2015 and December 2018 at our University Department of Surgery. We collated demographic factors, disease activity, imaging (MRI and endoanal ultrasound), surgical interventions, and medical treatment assessing the rate of fistula closure and fecal incontinence, 2 months and 1 year after surgery. RESULTS: Thirty-five IBD patients with anal fistula underwent surgery (28 Crohn's disease, four ulcerative colitis, and three indeterminate colitis). Twenty-seven patients presented with complex fistulas and eight with simple fistulas with 10 patients undergoing single-stage surgery. In 25 patients, a two-stage surgical approach was planned and performed (draining seton plus medical treatment and then second-stage surgery with curative intent). At 1 year of follow-up, the fistula healing rate was 50% for single-stage surgery and 60% for two-stage surgery (P = 0.09). Overall, 19.2% of patients developed postoperative fecal incontinence. A time interval greater than 12 months between surgeries is a favorable prognostic factor for fistula healing with the two-stage approach (P = 0.002). CONCLUSIONS: In our retrospective study, two-stage surgery in IBD patients presenting with complex perianal fistulous disease results in a better medium-term outcome with a longer time interval between surgeries.

Review of duodenal perforations after endoscopic retrograde cholangiopancreatography in Hospital Puerta de Hierro from 1999 to 2014.

INTRODUCTION: endoscopic retrograde cholangiopancreatography (ERCP) remains the gold standard in biliary and pancreatic pathology. Although the procedure has a significant morbidity and mortality rate. Algorithms are needed for the management and treatment of the associated complications. OBJECTIVE: to review the post-ERCP perforations treated in the Department of General Surgery of the Hospital Puerta de Hierro from 1999 to 2014. The results were evaluated according to the types of perforation and treatment. METHODS AND RESULTS: this is a descriptive and observational study of all post-ERCP perforations reported and treated by the Department of General Surgery of the Hospital Puerta de Hierro from 1999 to 2014. The following data were collected: indication for the test and findings, type of perforation, time and method of diagnosis, time to surgery and the technique used; the subsequent complications as well as the evolution and time of admission were registered. Results were evaluated according to the type of perforation (Stapfer classification) and the treatment performed. Thirty-six perforations were reported (21 type I, eight type II, two type III and five type IV), with an associated incidence of less than 1%. The diagnosis was immediate (in the first 24 hours) in 67% of cases; type I was the most frequent: 28 of 36 patients (77.7%) required surgery. The majority underwent a cholecystectomy followed by suture, intraoperative cholangiography, bile duct exploration and drainage whenever possible. Four patients died with type I perforations; two were intervened and two were managed conservatively. The most frequent complication was a collection/fistula which occurred in 21.42% of patients who underwent surgery. CONCLUSIONS: periduodenal perforations secondary to ERCP treatment should be oriented according to the clinical and radiological findings. In our experience, type I perforations require immediate surgical intervention, whereas type II and III perforations can be managed conservatively in some cases when there are no complications such as associated abdominal collections, peritoneal irritation and/or sepsis. Type IV perforations respond to conservative management.

Changes in the etiology, incidence and prognosis of acute lower respiratory track infections in human immunodeficiency virus patients.

AIM: To describe the incidence, the changes in the etiology and the prognosis of lower respiratory tract infection (LRTI) in HIV infected patients, presenting by the first time to the Emergency Department (ED), during years 2000-2010. STUDY DESIGN: Prospective collection of data. METHODS: Data were collected on the first visit of HIV-infected patients at our ED due to a LRTI, (defined according to the criteria of the European Respiratory Society), between 1/1/2000 and 31/12/2010. A series of epidemiological and laboratory variables as well as the need for admission to the intensive care unit (ICU). LRTI etiology were also collected. The influence ofthe mentioned variables on 30-day mortality were analyzed. RESULTS: One hundred thirty one patients were included. LRTI represented 27% of visits to the ED by HIV-infected patients. Mean age was 39±9 years. 72% of patients were males. 18% required admission to the ICU. The most frequent LRTI was pneumonia by P. jiroveci in 35 cases, bacterial penumonia in 27 and pulmonary tuberculosis in 20. LRTI incidence gradually reduced significantly over time from 6.13 × 1000 patients/year in year 2000 to 0.23 × 1000 patients/year in 2010 (p<0.05). Overall mortality was 14%. Logistic regression analysis showed that admission to ICU (p<0.004) and viral load (p<0.029) were independent variables predicting mortality. CONCLUSION: LRTI is a pathology with a decreasing incidence, probably related to the widespread utilization increased of HAART regimens. lts etiology has also been changing, but with a non negligible mortality, mostly when ICU admission was required.

Efficacy of amoxicillin/clavulanic acid after surgical drainage of perianal abscess in the prevention of the development of anal fistula (PERIQxA study): study protocol for a multicenter randomized, double-blind clinical trial.

BACKGROUND: Anorectal fistula, which is a relatively common pathology, is the chronic manifestation of the acute perirectal process that forms an anal abscess. The development of a fistula after incision and drainage of an anal abscess is seen in approximately 26-37%. Its treatment is a relevant topic, and the role of the use of antibiotic therapy in its prevention remains controversial, after the publication of several studies with contradictory results and several methodological limitations. Our hypothesis is that the combination of amoxicillin and clavulanic acid will reduce the incidence of anal fistula. METHOD: The aim of this study is to evaluate the efficacy of antibiotherapy after surgical drainage of perianal abscess in the development of perianal fistula. The PERIQxA study is a multicenter, randomized, double-blind controlled trial. The study has been designed to include 286 adult patients who will be randomly (1:1) assigned to either the experimental (amoxicillin/clavulanic acid 875/125 mg TDS for 7 days) or the control arm (placebo). The primary outcome measure is the percentage of patients that develop perianal fistula after surgery and during follow-up (6 months). DISCUSSION: This clinical trial is designed to evaluate the efficacy and safety of amoxicillin/clavulanic in the prevention of perianal fistula. The results of this study are expected to contribute to stablish the potential role of antibiotherapy in the therapeutics for anal abscess. TRIAL REGISTRATION: EudraCT Number: 2021-003376-14.

[de la evidencia y algoritmo adaptado Immunonutrition in fast-track surgical patients - Evidence review and adapted algorithm]. / Inmunonutrición del paciente quirúrgico en los procedimientos fast-track: revisión de la evidencia y algoritmo adaptado.

INTRODUCTION: Surgical stress predisposes patients to have immune dysfunction and an increased risk of infection. Malnourished surgical patients have higher postoperative morbidity and mortality rates, higher readmission rates, and higher hospital costs. The use of an immunomodulatory formula is associated in the ESPEN guidelines with a reduction in wound healing problems, suture failure, and infectious and global complications. Several authors have suggested that, since most clinical trials evaluating the efficacy of immunonutrition have been carried out in a traditional perioperative setting, it would be interesting to investigate its efficacy in a more controlled setting, such as in the ERAS (Enhanced Recovery after Surgery) protocol. The objective of this work was: a) to define the role that immunonutrition should play in ERAS protocols based on the best scientific evidence available; b) to analyze the difficulties that continue to exist in real-life clinical practice to screen the nutritional risk of patients; c) to make a proposal of algorithms adapted to the characteristics of our environment regarding the screening, assessment, and nutritional treatment of surgical patients in fast-track surgery.

INTRODUCCIÓN: El estrés quirúrgico predispone a los pacientes a la disfunción inmune y a un mayor riesgo de infección. Los pacientes quirúrgicos desnutridos presentan una mayor morbimortalidad posoperatoria, mayores tasas de reingreso y costes hospitalarios más elevados. En las guías de la ESPEN se asocia el uso de una fórmula inmunomoduladora a una reducción significativa de los problemas de la cicatrización de heridas, de los fallos de la sutura y de las complicaciones infecciosas y globales. Varios autores han sugerido que, dado que la mayoría de los ensayos clínicos que evalúan la eficacia de la inmunonutrición se han realizado en un entorno perioperatorio tradicional, sería interesante investigar su eficacia en un entorno más controlado, como en el protocolo ERAS (Enhanced Recovery after Surgery). El objetivo de este trabajo es: a) definir el papel que debe jugar la inmunonutrición en los protocolos ERAS sobre la base de la mejor evidencia científica; b) analizar las dificultades que siguen existiendo en la práctica clínica real para realizar el cribado del riesgo nutricional del paciente; c) proponer unos algoritmos adaptados a las características de nuestro entorno sobre el cribado, la valoración y el tratamiento nutricional del paciente quirúrgico en modalidad fast-track.

Revisión de las perforaciones duodenales tras colangiopancreatografía retrógrada endoscópica en el Hospital Puerta de Hierro de 1999 a 2014 / Review of duodenal perforations after endoscopic retrograde cholangiopancreatography in Hospital Puerta de Hierro from 1999 to 2014

Introducción: la colangiopancreatografía retrógrada endoscópica (CPRE) sigue siendo la prueba de elección para el diagnóstico y el tratamiento de la patología biliar y pancreática, pero cuenta con una tasa de morbimortalidad no desdeñable, por lo que se proponen algoritmos para el manejo y tratamiento de sus complicaciones. Objetivo: revisar las perforaciones post-CPRE tratadas en el Servicio de Cirugía General del Hospital Puerta de Hierro de 1999 a 2014, evaluando los resultados en función del tipo de perforación y el tratamiento. Métodos y resultados: se ha realizado un estudio descriptivo y observacional de todas las perforaciones post-CPRE comunicadas y tratadas por el Servicio de Cirugía General del Hospital Puerta de Hierro de 1999 a 2014, en relación a la indicación de la prueba y hallazgos, el tipo de perforación (clasificación de Stapfer), el tiempo hasta el diagnóstico y el método de diagnóstico, el tiempo hasta la intervención y la técnica empleada, las complicaciones posteriores, así como la evolución y el tiempo de ingreso. Los resultados se han evaluado en función del tipo de perforación (Stapfer) y del tipo de tratamiento realizado. Se comunicaron 36 perforaciones (21 de tipo I, ocho de tipo II, dos de tipo III y cinco de tipo IV), lo que supone una incidencia menor del 1%. El diagnóstico fue inmediato (en las primeras 24 horas) en el 67% de los casos, siendo las de tipo I las más frecuentes. Se intervino a 28 de los 36 pacientes (77,7%), realizándose en la mayoría una colecistectomía seguida, siempre que fue posible, de sutura, colangiografía intraoperatoria y exploración de la vía biliar y drenaje. Fallecieron cuatro pacientes (dos intervenidos y dos manejados de manera conservadora), todos con perforaciones de tipo I. La complicación más frecuente fue la colección/fístula, que apareció en el 21,42% de los pacientes intervenidos. Conclusiones: el tratamiento de las perforaciones periduodenales secundarias a CPRE debe orientarse en función de los hallazgos clínicos y radiológicos. Según nuestra experiencia, las perforaciones de tipo I requieren una intervención quirúrgica inmediata, mientras que las perforaciones tipo II y III permiten, en algunos casos, un manejo conservador, siempre ante la ausencia de complicaciones como colecciones abdominales asociadas y/o signos de sepsis o de irritación peritoneal. Las perforaciones tipo IV responden bien al manejo conservador

OBJETIVO: Describir la incidencia, la etiología y el pronóstico de la infección de las vías respiratorias bajas (IVRB) en los pacientes VIH, que acudieron a un Servicio de Urgencias (SU), durante el período del 2000-2010. DISEÑO: del estudio Estudio prospectivo de 10 años de evolución. MÉTODOS: Se recogió únicamente el primer episodio del paciente que acude al SU por IRVB (definida según laEuropean Respiratory Society). Se analizaron una serie de variables epidemiológicas y de laboratorio, así como la necesidad de ingreso en una unidad de cuidados intensivos (UCI). Se estudió la etiología de la IRVB y la incidencia. Finalmente se analizaron la influencia de las variables con la mortalidad a 30 días. Resultados Se incluyeron un total de 131 pacientes. La edad media fue de 39 ± 9 años. El 72% de los pacientes eran varones y el 18% de los pacientes requirieron ingreso en la UCI. La IRVB más frecuente fue la neumonía por P. jirovecci, seguida de la neumonía bacteriana en 27 y la tuberculosis pulmonar en 20. La incidencia de IRVB se ha ido reduciendo gradualmente de forma significativa, 6,13 × 1.000 pacientes/año en 2000 a 0,23 × 1.000 pacientes/año en 2010 (p < 0,05). El análisis de regresión logística mostró que la única variable que predijo mortalidad fue el ingreso en UCI (p < 0,05; OR: 73,01). CONCLUSIÓN: La IRVB es una enfermedad cuya incidencia y etiología han ido disminuyendo y cambiando respectivamente, probablemente en relación con la utilización generalizada del TAR. Sin embargo, todavía presenta una mortalidad nada despreciable, que es mayor cuando el paciente requiere ingreso en la UCI
