RESUMO

After bariatric surgery one of the most common complications is dysphagia. The etiology of this disease has not been fully elucidated but it is known that it may be due to structural changes due to surgery. This case describes a 65-year-old female with early and severe onset of dysphagia following laparoscopic sleeve gastrectomy. The patient's final diagnosis was postobesity surgery esophageal dysfunction and laparoscopic proximal gastrectomy with esophagojejunal Roux-en-Y anastomosis was performed. Physicians should be aware of this condition in order to offer early diagnosis and treatment.

RESUMEN Después de una cirugía bariátrica una de las complicaciones más comunes es la disfagia. La etiología de esta enfermedad no ha sido completamente dilucidada, pero se sabe que puede deberse a cambios estructurales debidos a la cirugía. En este reporte se describe el caso de una mujer de 65 años con disfagia severa de aparición temprana después de una en manga gástrica laparoscópica. El diagnóstico final del paciente fue de una disfunción esofágica posterior a una cirugía de obesidad y se planteó como manejo una gastrectomía proximal laparoscópica con anastomosis esofagoyeyunal en Y de Roux. Hay que tener en cuenta las complicaciones a corto y largo plazo que se pueden presentar luego de cirugías de obesidad para poder realizar un diagnóstico temprano y poder ofrecer un tratamiento adecuado.

RESUMO

A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic "bird-beak" termination. A Heller myotomy plus fundoplication and endoscopic balloon dilatation were conducted four months previously. Nevertheless, the symptoms persisted and the last high-resolution manometry study still showed achalasia type II. The patient underwent a peroral endoscopic esophageal myotomy (POEM). POEM is a feasible and safe procedure for experienced and properly-equipped health care delivery centers and could be used as a rescue treatment in refractory achalasia. We present the youngest patient with achalasia in our region who had a successful response to rescue POEM.

Un paciente varón de 15 años, con el diagnóstico de acalasia realizado 4 años antes, acudió a evaluación por presentar disfagia, regurgitación, pérdida de peso y dolor restroesternal. El esofagograma baritado evidenció una dilatación severa del esófago y la terminación clásica en "pico de pájaro". El paciente había sido sometido a una miotomía de Heller más fundoplicatura y posteriormente a una dilatación esofágica con balón 4 meses atrás. Sin embargo, los síntomas persistían y la última manometría de alta resolución reveló acalasia tipo II. Finalmente, se realizó una miotomía endoscópica por vía oral (POEM); el cual es un procedimiento seguro y accesible en centros experimentados y debidamente equipados, pudiendo ser una adecuada opción de tratamiento en casos de acalasia refractaria. Presentamos el caso del paciente más joven en nuestra región con acalasia con una respuesta exitosa a un POEM de rescate.

RESUMO

The whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is one of the most important agricultural pests and virus vectors worldwide. Bemisia tabaci is considered a complex of cryptic species with at least 44 species. Among them, the species Middle East-Asia Minor 1 (MEAM1, formerly B biotype) and Mediterranean (MED, formerly Q biotype) are the most important, and they have attained global status. In Brazil, MEAM1 was first reported in the 1990s and is currently the predominant species in the country, meanwhile, MED was recently reported in the South and Southeast regions and was found to be mainly associated with ornamental plants. Currently, an increasing problem in the management of whitefly infestations in greenhouses associated with bell pepper was observed in São Paulo State, Brazil. The whiteflies were collected and identified based on a microsatellite locus (primer pair BEM23F and BEM23R) and the mitochondrial cytochrome oxidase I gene followed by restriction fragment length polymorphism analysis and sequencing. We observed that MED was the predominant species collected on bell pepper, but it was also found on tomato, cucumber, eggplant, and weeds grown in greenhouses. In open field, we found MED on tomatoes, bell peppers, and eggplants. In addition, MED was identified in Goiás State in association with ornamental plants. The begomovirus Tomato severe rugose virus and the crinivirus Tomato chlorosis virus was detected on bell pepper and tomato, respectively. Only MED specimens were found associated with the virus-infected plants. Moreover, we also investigated the endosymbionts present in the MED whiteflies. The collected populations of B. tabaci MED harbored a diversity of secondary endosymbionts, with Hamiltonella (H) found predominantly in 89 specimens of the 129 tested. These results represent a new concern for Brazilian agriculture, especially for the management of the newly introduced whitefly MED species, which must be implemented to limit the spreading and establishment of this pest in different crops in this country.

RESUMO

El síndrome de Larsen (OMIM 150250) fue descripto por primera vez en 1950 como una entidad caracterizada por rasgos faciales distintos y dislocaciones de múltiples articulaciones, paladar hendido, pérdida de audición y anomalías en la columna vertebral. Se estima que la prevalencia del síndrome de Larsen es uno por cada cien mil nacidos vivos.El manejo de múltiples luxaciones de las grandes articulaciones a menudo resulta difícil, particularmente si un paciente tiene una luxación completa de la rodilla. Tratamos a un niño con una luxación recurrente en forma habitual femorotibial completa. Según nuestro conocimiento, no hemos encontrado en la literatura ningún trabajo que describa el tratamiento de esta rara patología en un paciente que luxe completamente la tibia anteriormente sobre el fémur de manera habitual


Larsen syndrome (OMIM 150250) was first described in 1950 as an entity characterized by distinct facial features and dislocations of the multiple large joint, and cleft palate, hearing loss, and spinal abnormalities. The prevalence of Larsen syndrome is estimated to be one in hundred thousand live births. Management of multiple large-joint dislocations often proves difficult with a tendency toward recurrence, particularly if a patient has complete dislocation of the knee. We treated a boy with a clinical habitual recurrence femorotibial luxation. We have not found in the literature any paper in our knowledge that describes the treatment of this rare pathology of a patient who completely dislocate the tibia anteriorly on the femur in the usual way

RESUMO

BACKGROUND: In recent years there has been an increase in the use of self-expanding metallic stents (SEMS) in patients with unresectable malignant stenosis of the bile duct. However, in Peru there are no reports on the safety and efficacy of this procedure. OBJECTIVE: To evaluate the safety and efficacy of the use of SEMS in the palliative management of malignant stenosis of the bile duct. MATERIALS AND METHODS: Retrospective cohort. All patients referred for placement of biliary SEMS as part of a palliative treatment between January 2016 and August 2018 were included. Rates of successful placement of SEMS, adequate palliation of the obstruction, and complications associated with the procedure were obtained. The patency of the prosthesis was evaluated during follow-up. Survival was determined after placement of the prosthesis. RESULTS: We included 32 patients with indication of palliative management due to an unresectable malignant stenosis of the bile duct. Pancreatic cancer (56.25%) followed by cholangiocarcinoma (31.25%) were the most frequent etiologies. A successful first-time placement rate of 96.97% was achieved. Adequate palliation of biliary obstruction was achieved in 100% of patients (p<0.05). Two SEMStc migrated during follow-up (6.25%) being managed with the placement of a new SEMSuc. CONCLUSIONS: The placement of SEMS is a safe and effective therapeutic strategy in the palliative management of patients with malignant obstruction of the biliary tract.

RESUMO

Antecedentes: En los últimos años se ha producido un incremento del uso de prótesis metálicas autoexpandibles (SEMS) en pacientes con estenosis malignas irresecables de la vía biliar. Sin embargo, en Perú no se cuentan con reportes sobre la seguridad y eficacia de este procedimiento. Objetivo: Evaluar la seguridad y eficacia del uso de las SEMS en el manejo paliativo de las estenosis malignas de la vía biliar. Materiales y métodos: Cohorte retrospectiva. Se incluyeron a todos los pacientes referidos para colocación de SEMS biliar como parte de un tratamiento paliativo entre enero del 2016 y agosto del 2018. Se obtuvieron las tasas de colocación exitosa de las SEMS, de paliación adecuada de la obstrucción y de complicaciones asociadas al procedimiento. Se evaluó la patencia de la prótesis durante el seguimiento. Se determinó la supervivencia luego de la colocación de la prótesis. Resultados: Se incluyeron 32 pacientes con indicación de manejo paliativo debido a una estenosis maligna irresecable de la vía biliar. El cáncer de páncreas (56,25%) seguido del colangiocarcinoma (31,25%) fueron las etiologías más frecuentes. Se alcanzó una tasa de colocación exitosa en primera intención de 96,97%. La paliación adecuada de la obstrucción biliar se alcanzó en el 100% de los pacientes (p<0,05). Dos SEMStc migraron durante el seguimiento (6,25%) siendo manejados con la colocación de una nueva SEMSnc. Conclusiones: La colocación de SEMS constituye una estrategia segura, con alta tasa de éxito terapéutico en el manejo paliativo de los pacientes con obstrucción maligna de la vía biliar.

RESUMO

Hyperplastic polyps are the most frequent benign epithelial gastric polyps. Although they are considered nonneoplastic, some cases have been reported with focal adenocarcinoma. We present the case of a 59-year-old woman with a sessile lesion of 15 mm on the distal gastric body associated with an extensive atrophic gastritis. Magnifying endoscopy with Fuji Intelligent Color Enhancement (FICE) revealed an irregular microsurface pattern at the apex, suggesting malignancy. A mucosectomy was performed. The histopathology revealed that the base corresponded to a hyperplastic polyp, where a tubular adenoma with high-grade dysplasia was established, with focal well-differentiated intramucosal tubular adenocarcinoma.

RESUMO

INTRODUCTION: The incidental detection of rectal neuroendocrine tumors (NET) has increased but there is no proper consensus about treatment. OBJECTIVE: Evaluate the efficacy and safety of endoscopic treatment for rectal NET less than 20 mm, with emphasis in "standardized treatment". MATERIAL AND METHODS: From January 2012 to April 2016, we included patients with rectal NET less than 20 mm resected by conventional EMR, EMR-B and ESD. We considered as "standardized treatment" the one that has precise indication and technical rigor (EMR-B for lesions ≤ 10 mm and ESD for lesions between 11 and 20 mm). We evaluate complete resection rates and incidence of complications. RESULTS: 23 patients with 23 rectal NET were included. The mean age was 52.96 ± 12.44 years. The mean tumor diameter was 8.8 ± 3.4 mm. The complete resection rates by conventional EMR, EMR-Band ESD were 50 (3/6), 92.8 (13/14) and 100% (3/3), respectively; while by standardized and conventional treatment were 100 (14/14) and 55.5% (5/9), respectively. Complications occurred in 4 cases (17.4%), bleeding in 2 and perforation in 2, all of them solved by endoscopy. CONCLUSIONS: Endoscopic treatment by EMR-B and ESD is efficacious and safe for rectal NET ≤ 20 mm. Standardized treatment improve the efficacy of endoscopic treatment.

RESUMO

Introducción: La detección incidental de tumores neuroendocrinos (TNE) rectales se ha incrementado, pero todavía no hay consenso apropiado para su tratamiento. Objetivo: Evaluar la eficacia y seguridad del tratamiento endoscópico de los TNE rectales menores de 20 mm, con énfasis en el "tratamiento estandarizado". Material y métodos: De enero del 2012 a abril del 2016, se incluyeron pacientes con TNE rectales menores de 20 mm que se resecaron mediante mucosectomía convencional (RME), mucosectomía asistida con endoligadura (RME-L) y disección submucosa endoscópica (DSE). Se consideró como "tratamiento estandarizado" aquel con indicación precisa y rigurosidad técnica (RME-L para lesiones ≤ 10 mm y DSE para lesiones entre 11 y 20 mm). Se evaluaron las tasas de resección completa, así como la incidencia de complicaciones. Resultados: 23 pacientes con 23 TNE rectales fueron incluidos. La edad promedio fue 52,96 ± 12,44 años. El tamaño promedio fue de 8,8 ± 3,4mm. Las tasas de resección completa con RME, RME-L y DSE fueron 50 (3/6), 92,8 (13/14) y 100% (3/3), respectivamente; mientras que con el tratamiento estandarizado y convencional fueron 100 (14/14) y 55,5% (5/9), respectivamente. Las complicaciones ocurrieron en 4 casos (17,4%), sangrado en 2 y perforación en 2, todos resueltos por endoscopía. Conclusiones: El tratamiento endoscópico mediante RME-L y DSE es eficaz y seguro para la resección de TNE rectales menores de 20 mm. El tratamiento estandarizado potencializa la eficacia de la terapia endoscópica.

RESUMO

Introducción: Los pacientes con pólipos colorrectales no pediculados grandes (PCNP-G) han sido tradicionalmente tratados quirúrgicamente. Los avances en la endoscopía terapéutica permiten que la resección endoscópica de estas lesiones pueda ser considerada como una alternativa a la cirugía. Objetivo: Evaluar la eficacia y seguridad de la resección endoscópica en pacientes con PCNP-G. Materiales y métodos: Cohorte prospectiva multicéntrica. Se incluyeron a todos los pacientes referidos para resección endoscópica de PCNP-G entre enero del 2012 y diciembre del 2015, seguidos hasta agosto del 2016. Se obtuvieron las tasas de resecciones exitosas, de recurrencia y de complicaciones. Se analizaron los factores predictivos asociados a resección no exitosa y a recurrencia. Resultados: Se incluyeron 107 pacientes con 115 PCNP-G. La tasa de resección exitosa fue de 92%. Las complicaciones más comunes fueron el sangrado (8,7%) y la perforación (2,6%). La tasa de recurrencia fue de 7%, todas tratadas endoscópicamente con éxito. Los factores predictivos de resección no exitosa fueron una medida >50 mm de la lesión resecada y la presencia de fibrosis; y el único factor predictivo de recurrencia fue una medida >50 mm del pólipo resecado. Conclusiones: La resección endoscópica de los PCNP-G es altamente eficaz y segura


Introduction: Patients with large non-pedunculated colorectal polyps (L-NPCP) have been traditionally treated with surgery. Advances in therapeutic endoscopy allow endoscopic resection of these lesions and can be considered as an alternative to surgery. Objective: To evaluate the efficacy and safety of endoscopic resection in patients with L-NPCP. Methods: A prospective multicentric cohort. All patients referred for endoscopic resection with L-NPCP between January 2012 and December 2015, followed until August 2016, were included. Rates of successful resection, recurrence and complications were obtained. Predictive factors associated with unsuccessful resection and recurrence were analyzed. Results: 115 L-NPCP in 107 patients were included. The rate of successful resection was 92%. The most common complications were bleeding (8.7%) and perforation (2.6%). The recurrence rate was 7%, all successfully treated with a new endoscopic session. Predictors of unsuccessful resection were a measure >50 mm of the lesion and the presence of fibrosis; and the only predictor of recurrence was a size of the polyp resected >50 mm. Conclusions: Endoscopic resection of L-NPCP is very efficacious and safe

RESUMO

INTRODUCTION: Endoscopic resection is the first option treatment of early gastric cancer with invasion to mucosa or superficial submucosa, because the risk of nodal metastasis is negligible. Then the prediction of tumor invasion is cardinal. OBJECTIVES: Determine the accuracy of endoscopic prediction for tumor invasion depth in early gastric neoplasia and define endoscopic characteristics associated with massive submucosal invasion. MATERIALS AND METHODS: Prospective sudy of diagnostic test validation. We included patients with early gastric neoplasias that were endoscopically or surgically resected from January 2012 to May 2016. Every lesion was looked for the presence of these features: margin elevation, central elevation, irregular surface, enlarged folds, size > 30mm and rigidity. The invasion prediction was categorized in: M-Sm1 when none feature was present, Sm2 when 2 or more features were present, and indeterminated when only one feature was present. We compared endoscopic prediction to pathological staging and determined diagnostic accuracy. RESULTS: The global accuracy for endoscopic prediction was 98.2%. Sensitivity, specificity, positive and negative predictive values for M-Sm1 prediction were 97.6, 100, 100 y 92.8%, and for Sm2 prediction were 100, 97.6, 92.8 y 97.6%, respectively. Rigidity, irregular Surface, margin elevation and enlarged folds were associated with Sm2 invasion. CONCLUSIONS: Endoscopic prediction of tumor invasion depth in early gastric neoplasia is very accurate. The main endoscopic feature associated with Sm2 invasion is rigidity.

RESUMO

BACKGROUND: In Peru, there are still no local studies designed for evaluating the performance of clinical guidelines designed to stratify patients according to probability of choledocholithiasis. OBJECTIVES: To evaluate the performance of predictive criteria proposed by the American Society for Gastrointestinal Endoscopy (ASGE) in diagnosis of choledocholithiasis. MATERIALS AND METHODS: A retrospective cohort study conducted in a hospital in Lima (Rebagliati hospital). Were included all patients with suspected choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP) between July 2014 and June 2015. Predictors of choledocholithiasis proposed by the ASGE and the diagnostic performance of the risk categories were evaluated. RESULTS: 118 patients met the inclusion criteria. In multivariate analysis, only age >55 years (OR: 3.07 [95: 1.14-8.31], p = 0.027) and the finding of stones in the common bile duct by abdominal ultrasound (OR: 1.68 [95% CI: 1.09-2.59], p = 0.018) were associated with the presence of choledocholithiasis on ERCP. The performance of the high and intermediate risk categories were 75.82% and 70.37% respectively. The performance of the high-risk category improved to 85.90% using a second set of biochemical markers. CONCLUSIONS: The performance of the predictors and risk categories proposed by the ASGE in diagnosis of choledocholithiasis is acceptable in our hospital, according to the proposed standards; however, it must be further improved to prevent the use of diagnostic ERCP.

RESUMO

Antecedentes: En el Perú no se cuenta con ningún estudio que evalúe el rendimiento de la guía clínica actual orientada a estratificar a los pacientes según probabilidad de presentar coledocolitiasis. Objetivos: Evaluar el rendimiento de los criterios predictivos propuestos por la Sociedad Americana de Endoscopía Gastrointestinal (ASGE) en el diagnóstico de coledocolitiasis. Materiales y métodos: Cohorte retrospectiva realizada en el hospital Rebagliati. Se incluyeron a todos los pacientes con sospecha de coledocolitiasis que contaron con una colangiopancreatografía retrógrada endoscópica (CPRE) entre julio del 2014 y junio del 2015. Se evaluaron los predictores de coledocolitiasis propuestos por la ASGE y el rendimiento diagnóstico de las categorías de riesgo. Resultados: Se incluyeron 118 pacientes que cumplieron con los criterios de inclusión. En el análisis multivariado sólo la edad >55 años (OR:3,07, [IC 95: 1,14-8,31], p=0,027) y el hallazgo de litiasis en la vía biliar común mediante ecografía (OR: 1,68 [IC 95%: 1,09-2,59], p=0,018) se asociaron a la existencia de coledocolitiasis en la CPRE. Los rendimientos de las categorías de riesgo elevado y de riesgo intermedio fueron de 75,82% y 70,37% respectivamente. El rendimiento de la categoría de riesgo elevado mejoró a 85,90% utilizando un segundo set de pruebas de laboratorio control. Conclusiones: El rendimiento de los predictores y las categorías de riesgo propuestos por la ASGE en el diagnóstico de coledocolitiasis es aceptable en nuestro hospital, acorde con los estándares propuestos; sin embargo, creemos que aún debe mejorar para evitar el uso de CPREs diagnósticas.


Background: In Peru, there are still no local studies designed for evaluating the performance of clinical guidelines designed to stratify patients according to probability of choledocholithiasis. Objectives: To evaluate the performance of predictive criteria proposed by the American Society for Gastrointestinal Endoscopy (ASGE) in diagnosis of choledocholithiasis. Materials and methods: A retrospective cohort study conducted in a hospital in Lima (Rebagliati hospital). Were included all patients with suspected choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP) between July 2014 and June 2015. Predictors of choledocholithiasis proposed by the ASGE and the diagnostic performance of the risk categories were evaluated. Results: 118 patients met the inclusion criteria. In multivariate analysis, only age >55 years (OR: 3.07 [95: 1.14-8.31], p = 0.027) and the finding of stones in the common bile duct by abdominal ultrasound (OR: 1.68 [95% CI: 1.09-2.59], p = 0.018) were associated with the presence of choledocholithiasis on ERCP. The performance of the high and intermediate risk categories were 75.82% and 70.37% respectively. The performance of the high-risk category improved to 85.90% using a second set of biochemical markers. Conclusions: The performance of the predictors and risk categories proposed by the ASGE in diagnosis of choledocholithiasis is acceptable in our hospital, according to the proposed standards; however, it must be further improved to prevent the use of diagnostic ERCP.

RESUMO

Introduction: Endoscopic resection is the first option treatment of early gastric cancer with invasion to mucosa or superficial submucosa, because the risk of nodal metastasis is negligible. Then the prediction of tumor invasion is cardinal. Objectives: Determine the accuracy of endoscopic prediction for tumor invasion depth in early gastric neoplasia and define endoscopic characteristics associated with massive submucosal invasion. Materials and methods: Prospective sudy of diagnostic test validation. We included patients with early gastric neoplasias that were endoscopically or surgically resected from January 2012 to May 2016. Every lesion was looked for the presence of these features: margin elevation, central elevation, irregular surface, enlarged folds, size > 30mm and rigidity. The invasion prediction was categorized in: M-Sm1 when none feature was present, Sm2 when 2 or more features were present, and indeterminated when only one feature was present. We compared endoscopic prediction to pathological staging and determined diagnostic accuracy. Results: The global accuracy for endoscopic prediction was 98.2%. Sensitivity, specificity, positive and negative predictive values for M-Sm1 prediction were 97.6, 100, 100 y 92.8%, and for Sm2 prediction were 100, 97.6, 92.8 y 97.6%, respectively. Rigidity, irregular Surface, margin elevation and enlarged folds were associated with Sm2 invasion. Conclusions: Endoscopic prediction of tumor invasion depth in early gastric neoplasia is very accurate. The main endoscopic feature associated with Sm2 invasion is rigidity.


Introducción: La resección endoscópica constituye el tratamiento de elección del cáncer gástrico temprano con invasión a la mucosa o submucosa superficial, pues tiene riesgo casi nulo de metástasis ganglionar. Por tanto, la predicción de invasión tumorales cardinal. Objetivos: Determinar la precisión de la predicción de invasión tumoral de neoplasia gástrica temprana por endoscopía convencional y definir características endoscópicas asociadas a invasión submucosa masiva. Material y métodos: Estudio prospectivo de validación de una prueba diagnóstica. Se incluyeron todos los pacientes con neoplasias gástricas tempranas que fueron resecadas endoscópica o quirúrgicamente de enero 2012 a mayo 2016. En cada lesión se definió la presencia de las siguientes características: Elevación de márgenes, elevación central, irregularidad de la superficie, engrosamiento de pliegues, tamaño >30 mm y rigidez. La predicción de invasión se categorizó en: M-Sm1 cuando no tenía ninguna característica, Sm2 cuando tenía 2 o más características, e indeterminada cuando sólo tenía una característica. Se comparó la predicción endoscópica con el estadiaje patológico de los especímenes y se determinó su precisión diagnóstica. Resultados: La precisión global de la predicción endoscópica fue de 98,2%. La sensibilidad, especificidad, VPP y VPN para la predicción M-Sm1 fue 97,6, 100, 100 y 92,8%, y para la predicción Sm2 fue 100, 97,6, 92,8 y 97,6%, respectivamente. La rigidez, irregularidad en la superficie, elevación de los márgenes y engrosamiento de pliegues, se asociaron significativamente con invasión Sm2. Conclusiones: La predicción endoscópica de invasión tumoral en neoplasia gástrica temprana es muy precisa. La principal característica endoscópica asociada a invasión Sm2 es la rigidez.

RESUMO

INTRODUCTION: Patients with large non-pedunculated colorectal polyps (L-NPCP) have been traditionally treated with surgery. Advances in therapeutic endoscopy allow endoscopic resection of these lesions and can be considered as an alternative to surgery. OBJECTIVE: To evaluate the efficacy and safety of endoscopic resection in patients with L-NPCP. METHODS: A prospective multicentric cohort. All patients referred for endoscopic resection with L-NPCP between January 2012 and December 2015, followed until August 2016, were included. Rates of successful resection, recurrence and complications were obtained. Predictive factors associated with unsuccessful resection and recurrence were analyzed. RESULTS: 115 L-NPCP in 107 patients were included. The rate of successful resection was 92%. The most common complications were bleeding (8.7%) and perforation (2.6%). The recurrence rate was 7%, all successfully treated with a new endoscopic session. Predictors of unsuccessful resection were a measure >50 mm of the lesion and the presence of fibrosis; and the only predictor of recurrence was a size of the polyp resected >50 mm. CONCLUSIONS: Endoscopic resection of L-NPCP is very efficacious and safe.

RESUMO

Objetivo: Describir la experiencia clínica con la técnica de dilatación de la esfinterotomía papilar con balones de gran diámetro en pacientes con coledocolitiasis de difícil extracción. Materiales y métodos: Estudio retrospectivo, diseño descriptivo. Serie de Casos. Se analizaron las historias clínicas de 18 pacientes que fueron sometidos a colangiopancreatografía retrograda endoscópica (CPRE) más dilatación papilar con balón de gran diámetro (DPBGD) por presentar coledocolitiasis de gran tamaño (≥15 mm), desproporción de diámetro entre cálculo y colédoco distal y/o papila yuxtadiverticular. Se emplearon balones dilatadores CRETM entre 12 y 20mm de diámetro. Se consignaron datos como éxito del procedimiento, uso de litotricia; así como complicaciones durante el procedimiento. Resultados: La edad promedio fue 66,1 años. Hubo predominio del género femenino (66,7%). El tamaño promedio de los cálculos en vía biliar fue de 16,7 mm. Las indicaciones de DPBGD fueron: coledocolitiasis gigante (12 pacientes, 66,7%), discordancia entre el diámetro del cálculo y el colédoco distal (6 pacientes, 33,3%). El diámetro de los balones de dilatación más frecuentemente empleados fueron: 15 mm (8 pacientes, 44,4%), 18 mm (5 pacientes, 27,8%), 12 mm (3 pacientes, 16,7%) y 20 mm (2 pacientes, 11,1%). Se consiguió la extracción completa de los cálculos en 15 pacientes (83,3%). Se precisó litotricia en 4 pacientes (22,2%). Hubo 3 pacientes en los que la extracción con balón fue frustra, realizándose manejo quirúrgico. Se reportó 1 caso de pancreatitis aguda leve (5,5%). Conclusiones: Los resultados demuestran que la dilatación con balón es una alternativa segura y eficaz en el manejo de los cálculos en vía biliar de difícil extracción


Objective: The aim of this study was to report the initial experience of the combined use of biliary sphincterotomy plus balloon dilatation of the papilla for management of large stones. Materials and methods: Design: Retrospective, descriptive. This study included 18 patients in whom a hydrostatic dilatation of the papilla with large balloons was performed between June 2012 and April 2014. Patients had multiple large stones, tapered distal common bile duct, previous sphincterotomy, or peri/ intradiverticular papilla. CRE™ dilatation balloons with diameters ranging from 12 to 20 mm were used. Data were recorded as successful procedure, use of lithotripsy and complications during the procedure. Results: The average age was 66.1 years. There was a predominance of the female gender (66.7%). The average size of the bile duct stones was 16.7 mm. The main indications were: giant choledocholithiasis (12 patients, 66.7%) and tapered distal common bile duct (6 patients, 33.3%). The dilatation balloons diameter used were: 15 mm (8 patients, 44.4%), 18 mm (5 patients, 27.8%), 12 mm (3 patients, 16.7%) and 20 mm (2 patients, 11.1%). Complete stone clearance was achieved in 15 patients (83.3%). Lithotripsy was performed in 4 patients (22.2%). There were 3 patients in whom the removal with balloon was unsuccessful, performed surgical management. It was reported 1 case of mild acute pancreatitis (5.5%). Conclusions: The results show that endoscopic papillary large balloon dilation after sphincterotomy is a safe and effective technique for treatment of difficult bile duct stones

RESUMO

Introduction of a novel influenza virus into the human population leads to the occurrence of pandemic events, such as the one caused by pandemic influenza A (H1N1) 2009 virus. The severity of infections caused by this virus in young adults was greater than that observed in patients with seasonal influenza. Fatal cases have been associated with an abnormal innate, proinflammatory immune response. A critical role for natural killer cells during the initial responses to influenza infections has been suggested. In this study, we assessed the association of killer-cell immunoglobulin-like receptors (KIRs) with disease severity by comparing KIR gene content in patients with mild and severe pandemic influenza virus infections to a control group. We found that activator (KIR3DS1 and KIR2DS5) and inhibitory (KIR2DL5) genes, encoded in group B haplotypes containing the cB01, cB03 and tB01 motifs, are associated with severe pandemic influenza A (H1N1) 2009 infections. Better understanding of how genetic variability contributes to influenza virus pathogenesis may help to the development of immune intervention strategies aiming at controlling the severity of disease.
