ABSTRACT

ABSTRACT BACKGROUND: Vesicourethral anastomotic stenosis (VUAS) following retropubic radical prostatectomy (RRP) significantly worsens quality of life. OBJECTIVES: To investigate the relationship between proliferative hypertrophic scar formation and VUAS, and predict more appropriate surgical intervention for preventing recurrent VUAS. DESIGN AND SETTING: Retrospective cross-sectional single-center study on data covering January 2009 to December 2019. METHODS: Among 573 male patients who underwent RRP due to prostate cancer, 80 with VUAS were included. They were divided into two groups according to VUAS treatment method: dilatation using Amplatz renal dilators (39 patients); or endoscopic bladder neck incision/resection (41 patients). The Vancouver scar scale (VSS) was used to evaluate the characteristics of scars that occurred for any reason before development of VUAS. RESULTS: Over a median follow-up of 72 months (range 12-105) after RRP, 17 patients (21.3%) had recurrence of VUAS. Although the treatment success rates were similar (79.5% versus 78.0%; P = 0.875), receiver operating characteristic (ROC) curve analysis indicated that dilatation using Amplatz dilators rather than endoscopic bladder neck incision/resection in patients with VSS scores 4, 5 and 6 may significantly reduce VUAS recurrence. A strong positive relationship was observed between VSS and total number of VUAS occurrences (r: 0.689; P < 0.001). VSS score (odds ratio, OR: 5.380; P < 0.001) and time until occurrence of VUAS (OR: 1.628; P = 0.008) were the most significant predictors for VUAS recurrence. CONCLUSIONS: VSS score can be used as a prediction tool for choosing more appropriate surgical intervention, for preventing recurrent VUAS.

ABSTRACT

La obstrucción de la salida gástrica es una afección infrecuente en la edad pediátrica. Tradicionalmente, la cirugía ha sido el modo de tratamiento estándar, pero está asociada a mayor morbimortalidad. El tratamiento endoscópico ha surgido como una alternativa al tratamiento convencional. Presentamos el caso de un paciente de 4 años con estenosis prepilórica secundaria a enfermedad ulceropéptica. El cuadro clínico empezó con vómitos y dolor abdominal de 2 meses de evolución. Frente a la falta de respuesta al tratamiento médico y a la dilatación endoscópica con balón, se realizaron incisiones radiadas con electrocauterio e inyecciones de esteroides. La terapéutica endoscópica con balón debería ser el primer gesto terapéutico en este tipo de estenosis refractarias al tratamiento médico


Gastric outlet obstruction is an uncommon condition in children. Traditionally, surgery has been the standard mode of treatment, but it is associated with higher morbidity and mortality. Endoscopic treatment has emerged as an alternative to conventional treatment. We present the case of a 4-year-old patient with refractory prepyloric stenosis secondary to peptic ulcer disease. The picture begins with vomiting and abdominal pain of 2 months of evolution. Pre-pyloric stenosis was confirmed. Faced with the lack of response to medical treatment and balloon dilation, radiated incisions were made with electrocautery and steroid injections. When medical treatment is not sufficient, endoscopic balloon therapy should be the first therapeutic gesture in this type of stenosis; given its refractoriness, we believe it is important to highlight the usefulness of endoscopic treatment, which could prevent surgery and associated morbidity and mortality.

ABSTRACT

Abstract Infantile scimitar syndrome (SS) is a rare congenital heart disease and has high mortality. Guidelines have not been established, but surgery is indicated in symptomatic patients. Despite the various surgical approaches, outcomes continue to be disappointing. We present our surgical experience with an infantile SS patient who had stenotic pulmonary veins contralateral to the hypoplastic lung with complicated anatomy. There are few cases with this complex pathology in the literature. Moreover, our patient was the first transplant-free survivor with this complexity in the literature.

ABSTRACT

Abstract Degenerative lumbar spinal stenosis is the most frequent cause of low back pain and/or sciatica in the elderly patient. Epidemiology, pathophysiology, clinical manifestations and testing are reviewed in a wide current bibliographic investigation. The importance of the relationship between clinical presentation and imaging study, especially magnetic resonance imaging (MRI), is emphasized. Prior to treatment indication, it is necessary to identify the precise location of pain, as well as the differential diagnosis between neurological and vascular lameness. Conservative treatment combining medications with various physical therapy techniques solves the problem in most cases, while therapeutic testing with injections, whether epidural, foraminal or facetary, is performed when pain does not subside with conservative treatment and before surgery is indicated. Injections usually perform better results in relieving sciatica symptoms and less in neurological lameness. Equine tail and/or root decompression associated or not with fusion is the gold standard when surgical intervention is required. Fusion after decompression is necessary in cases with segmental instability, such as degenerative spondylolisthesis. When canal stenosis occurs at multiple levels and is accompanied by axis deviation, whether coronal and/or sagittal, correction of axis deviations should be performed in addition to decompression and fusion, especially of the sagittal axis, in which a lumbar lordosis correction is required with techniques that correct the rectified lordosis to values close to the pelvic incidence.


Resumo A estenose degenerativa do canal vertebral lombar é a causa mais frequente de dor lombar e/ou ciática no paciente idoso; sua epidemiologia, fisiopatogenia, manifestações e testes clínicos são revistos em ampla investigação bibliográfica atual. A importância da relação entre a clínica e o estudo por imagens, principalmente a ressonância magnética (RM), é ressaltada. Antes da indicação do tratamento, é necessário identificar a localização precisa da dor, bem como o diagnóstico diferencial entre a claudicação neurogênica e a vascular. O tratamento conservador associando medicações com as diversas técnicas fisioterápicas resolve o problema na maioria dos casos, já o teste terapêutico com os bloqueios, seja epidural, foraminal ou facetário, é realizado quando as dores não cedem com o tratamento conservador e antes da indicação da cirurgia. Os bloqueios costumam dar melhores resultados no alívio dos sintomas de ciatalgia e menos no quadro de claudicação neurogênica. A descompressão da cauda equina e/ou radicular associada ou não à artrodese é o padrão ouro quando a intervenção cirúrgica é necessária. A artrodese após a descompressão é necessária nos casos com instabilidade segmentar, como na espondilolistese degenerativa. Quando a estenose de canal acontece em múltiplos níveis e vem acompanhada de desvio de eixo, seja coronal e/ou sagital, deve ser realizada, além das descompressões e artrodese, a correção dos desvios de eixo, principalmente o eixo sagital, quando a correção da lordose lombar se impõe com técnicas que corrigem a lordose retificada para valores próximos à incidência pélvica.

ABSTRACT

La endarterectomía carotídea es el procedimiento quirúrgico de elección para tratar la obstrucción y/o estenosis de la arteria carótida extracraneal y prevenir los eventos neurológicos. La aparición de síntomas depende de la gravedad y progresión de la lesión, del adecuado flujo colateral, de las características de la placa y de la presencia de otros factores de riesgo. Analizamos el resultado de la endarterectomía carotídea como procedimiento quirúrgico de elección para la estenosis carotídea, así como la presentación de un caso clínico de un adulto mayor con oclusión del 100% y la resolución completa de los síntomas posteriores al procedimiento quirúrgico (AU)


Endarterectomy of the carotid is the surgical procedure of choice to treat obstruction and/or stenosis of the extracranial carotid artery and prevent neurological events. The appearance of symptoms depends on the severity and progression of the lesion, the adequate collateral flow, the characteristics of the plaque and the presence of other risk factors. We analyze the result of carotid endarterectomy as the surgical procedure of choice for carotid stenosis as well as the presentation of a clinical case of an elderly adult patient with 100% occlusion and complete resolution of symptoms after the surgical procedure (AU)

ABSTRACT

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

ABSTRACT

BACKGROUND@#Drug-coated balloons (DCBs) have emerged as potential alternatives to drug-eluting stents in specific lesion subsets for de novo coronary lesions. Quantitative flow ratio (QFR) is a method based on the three-dimensional quantitative coronary angiography and contrast flow velocity during coronary angiography (CAG), obviating the need for an invasive fractional flow reserve procedural. This study aimed to assess the serial angiographic changes of de novo lesions post-DCB therapy and further explore the cut-off values of lesion and vessel QFR, which predict vessel restenosis (diameter stenosis [DS] ≥50%) at mid-term follow-up.@*METHODS@#The data of patients who underwent DCB therapy between January 2014 and December 2019 from the multicenter hospital were retrospectively collected for QFR analysis. From their QFR performances, which were analyzed by CAG images at follow-up, we divided them into two groups: group A, showing target vessel DS ≥50%, and group B, showing target vessel DS <50%. The median follow-up time was 287 days in group A and 227 days in group B. We compared the clinical characteristics, parameters during DCB therapy, and QFR performances, which were analyzed by CAG images between the two groups, in need to explore the cut-off value of lesion/vessel QFR which can predict vessel restenosis. Student's t test was used for the comparison of normally distributed continuous data, Mann-Whitney U test for the comparison of non-normally distributed continuous data, and receiver operating characteristic (ROC) curves for the evaluation of QFR performance which can predict vessel restenosis (DS ≥50%) at mid-term follow-up using the area under the curve (AUC).@*RESULTS@#A total of 112 patients with 112 target vessels were enrolled in this study. Group A had 41 patients, while group B had 71. Vessel QFR and lesion QFR were lower in group A than in group B post-DCB therapy, and the cut-off values of lesion QFR and vessel QFR in the ROC analysis to predict target vessel DS ≥50% post-DCB therapy were 0.905 (AUC, 0.741 [95% confidence interval, CI: 0.645, 0.837]; sensitivity, 0.817; specificity, 0.561; P < 0.001) and 0.890 (AUC, 0.796 [95% CI: 0.709, 0.882]; sensitivity, 0.746; specificity, 0.780; P < 0.001).@*CONCLUSIONS@#The cut-off values of lesion QFR and vessel QFR can assist in predicting the angiographic changes post-DCB therapy. When lesion/vessel QFR values are <0.905/0.890 post-DCB therapy, a higher risk of vessel restenosis is potentially predicted at follow-up.

ABSTRACT

Introducción: La estenosis de la vía biliar es una afección poco frecuente, pero con serias repercusiones en la morbilidad de los pacientes. La gran mayoría ocurre después de la cirugía hepatobiliar: la colecistectomía es la más común de estas cirugías. El reconocimiento temprano y el enfoque multidisciplinario adecuado es la piedra angular para lograr obtener resultados finales óptimos. Objetivo: Describir el tratamiento endoscópico de los pacientes con estenosis poscolescistectomía atendidos en el Instituto de Gastroenterología (Cuba). Métodos: Se realizó un estudio retrospectivo descriptivo de los pacientes con diagnóstico de estenosis biliar poscolescitectomía. Se determinaron variables sociodemográficas, clínicas y endoscópicas de interés. Resultados: Se estudiaron 16 pacientes. Predominaron las mujeres menores de 50 años. El 75 por ciento de los pacientes tenían antecedente de colecistectomía laparoscópica. Las estenosis biliares tipo I y III, según la clasificación de Bismuth, fueron las más usuales. El tratamiento endoscópico mediante colangiografía retrógrada endoscópica (CPRE) con colocación de múltiples prótesis plásticas fue la conducta terapéutica más empleada. Conclusiones: En las estenosis poscolescitectomía los procedimientos endoscópicos se han convertido en el tratamiento de elección, como un procedimiento menos invasivo, con baja morbilidad y mortalidad, con evidentes resultados comparables a los logrados con procedimientos quirúrgicos no endoscópicos(AU)


Introduction: Bile duct stenosis is an infrequent condition, but it seriously affects patient morbidity. The vast majority of cases occur after hepatobiliary surgery, cholecystectomy being the most common of such surgeries. Early recognition and an appropriate multidisciplinary approach are the cornerstones to achieve optimal final results. Objective: Describe the endoscopic treatment of patients with postcholecystectomy stenosis cared for at the Institute of Gastroenterology in Cuba. Methods: A retrospective descriptive study was conducted of the patients diagnosed with postcholecystectomy bile duct stenosis. Determination was made of sociodemographic, clinical and endoscopic variables of interest. Results: A total 16 patients were studied. There was a predominance of women aged under 50 years. 75 percent of the patients had a history of laparoscopic cholecystectomy. The most common bile duct stenoses were types I and III by Bismuth's classification. The most frequent therapeutic management was endoscopic treatment by endoscopic retrograde cholangiography (ERCP) with placement of multiple plastic prostheses. Conclusions: Endoscopic procedures have become the treatment of choice in postcholecystectomy stenosis. They are less invasive, their morbidity and mortality are low, and their results are comparable to those of non-endoscopic surgical procedures(AU)

ABSTRACT

ABSTRACT BACKGROUND Biliary complications remain one of the most important causes of morbidity and graft loss after liver transplant (LT). Endoscopic therapy of biliary complications has proven to be effective over time, leaving surgical treatment restricted to only very few cases. However, we cannot yet predict which patients will have the greatest potential to benefit from endoscopic treatment. OBJECTIVE On this premise we decide to conduct this study to evaluate the role and safety of single operator cholangioscopy (SOC) in the endoscopic treatment of post-LT biliary anastomotic strictures (AS). METHODS: Between March/2016 and June/2017, 20 consecutive patients referred for endoscopic treatment for biliary anastomotic stricture were included in this prospective observational cohort study. Inclusion criteria were age over 18 years old, and a deceased LT performed within at least 30 days. Exclusion criteria were non-anastomotic biliary stricture, biliary leakage, cast syndrome, any previous endoscopic therapy, pregnancy and inability to provide informed consent. All patients underwent SOC before endoscopic therapy with fully covered self-expandable metal stent (FCSEMS) and after stent removal. RESULTS: At pre-treatment SOC, stricture orifice and fibrotic changes could be visualized in all patients, vascular changes and surgical sutures in 60% and acute inflammatory changes in 30%. SOC was essential for guidewire placement in five cases. FCSEMS was successfully deployed in all patients. Stricture resolution rate was 44.4% (median stent indwelling 372 days). Stricture recurrence was 12.5% (median follow-up of 543 days). Adverse events were distal (66.6%) and proximal (5.5%) stent migration, stent occlusion (16.6%), severe abdominal pain (10%) and mild acute pancreatitis (10%). SOC was repeated after FCSEMS removal. Post-treatment SOC showed fibrotic changes in all but one patient; vascular and acute inflammatory changes were less frequent in comparison to index procedure. The disappearance of suture material was remarkable. None of the cholangioscopic findings were statistically correlated to treatment outcome or stricture recurrence. CONCLUSION: Endoscopic retrograde cholangiography with SOC is feasible in post-LT patients with AS. Cholangioscopic findings can be classified into fibrotic, vascular and acute inflammatory changes. Cholangioscopy may be helpful to assist guidewire passage, but Its overall role for changing management is post-LT patients was not demonstrated.


RESUMO CONTEXTO: As complicações biliares continuam sendo uma das principais causas de morbidade e perda do enxerto após o transplante hepático. O tratamento endoscópico das complicações biliares provou ser eficaz ao longo do tempo, deixando o tratamento cirúrgico restrito a casos de exceção. No entanto, ainda não podemos prever quais pacientes terão maior potencial de se beneficiar da terapia endoscópica. OBJETIVO: Nesta premissa, decidimos realizar este estudo para avaliar o papel e a segurança da colangioscopia peroral de operador único (CPO) no tratamento endoscópico das estenoses anastomóticas biliares (EA) pós-transplante hepático. MÉTODOS: Entre março de 2016 e junho de 2017, 20 pacientes consecutivos encaminhados para tratamento endoscópico da EA biliar foram incluídos neste estudo prospectivo de coorte observacional. Os critérios de inclusão foram idade superior a 18 anos e um transplante hepático de doador falecido realizado há pelo menos 30 dias. Pacientes com estenose biliar não anastomótica, fístula biliar, "cast" síndrome, qualquer terapia endoscópica prévia, gravidez e incapacidade de fornecer consentimento informado foram excluídos. Todos os pacientes foram submetidos à CPO antes da terapia endoscópica com prótese metálica autoexpansível totalmente coberta (PMAEC) e após a sua remoção. RESULTADOS: Na CPO realizada antes do tratamento endoscópico, o orifício de estenose e alterações fibróticas foram visualizadas em todos os pacientes, alterações vasculares e a presença de suturas cirúrgicas em 60%, enquanto alterações inflamatórias agudas em 30%. A CPO foi determinante para a transposição do fio-guia através da estenose em cinco casos. Uma PMAEC foi implantada com sucesso em todos os pacientes. A taxa de resolução da estenose foi de 44,4% (tempo médio de permanência de 372 dias). A recorrência da EA foi de 12,5% (acompanhamento médio de 543 dias). Os eventos adversos foram migração distal (66,6%) e proximal (5,5%) da prótese metálica, oclusão da PMAEC (16,6%), dor abdominal intensa (10%) e pancreatite aguda leve (10%). A CPO foi repetida após a remoção da PMAEC. A colangioscopia realizada após o tratamento endoscópico mostrou alterações fibróticas em todos, exceto em um paciente; alterações vasculares e inflamatórias agudas foram menos frequentes em comparação à CPO inicial. O desaparecimento do material de sutura, observado em todos os casos, foi notável. Nenhum dos achados colangioscópicos foram estatisticamente correlacionados ao resultado do tratamento ou à recorrência de estenose. CONCLUSÃO: A colangioscopia peroral é viável nos pacientes pós-transplante hepático com estenose biliar anastomótica. Os achados colangioscópicos podem ser classificados em alterações inflamatórias agudas, fibróticas e vasculares. A colangioscopia pode ser útil para auxiliar na passagem do fio-guia, mas seu papel geral na mudança de tratamento nos pacientes pós-transplante hepático não foi demonstrado.

ABSTRACT

La enfermedad aorto-ilíaca es una entidad que, por su localización y distribución, plantea un reto para el radiólogo intervencionista. Existen diferentes técnicas endovasculares que ofrecen una buena permeabilidad a mediano y largo plazos, a partir de una selección apropiada de los pacientes. Este artículo tuvo como objetivo caracterizar la técnica de kissing stent como una alternativa terapéutica más, mínimamente invasiva, en los pacientes con enfermedad aorto-ilíaca. En este sentido, se presenta el caso de una mujer de 60 años con claudicación intermitente de 3 meses de evolución, con cambios tróficos de la piel a predominio derecho, en quien se documentó una estenosis aorto-ilíaca bilateral según el Trans-Atlantic Inter-Society Consensus Working Group II tipo A. Se realizó angioplastia con balón y stent autoexpandibles de ambas ilíacas comunes mediante la técnica de kissing stent. En el seguimiento anual, la paciente toleró el ejercicio, y al examen físico, los pulsos periféricos estuvieron presentes. Además, el manejo endovascular de las lesiones estenótica aorto-ilíacas mediante la técnica de kissing stent resulta segura, menos cruenta y con buenos resultados a mediano plazo, que se debe sustentar en una selección apropiada de los pacientes(AU)


Aortoiliac disease is an entity that, due to its location and distribution, poses a challenge for the interventional radiologist. There are different endovascular techniques offering good permeability in the mid- and long terms, based on appropriate selection of patients. This article aimed at characterizing the kissing stent technique as another minimally-invasive therapeutic alternative in patients with aortoiliac disease. In this respect, the case is presented of a 60-year-old woman with intermittent claudication of three months of evolution, with trophic changes of the skin, predominantly on the right side, and in whom a bilateral aortoiliac disease was documented as type A according to the Trans-Atlantic Inter-Society Consensus Working Group II. Balloon angioplasty and self-expanding stenting of both common iliac arteries were performed using the kissing stent technique. At annual follow-up, the patient tolerated exercise; and, on physical examination, peripheral pulses were present. In addition, endovascular management of aortoiliac disease stenotic lesions using the kissing stent technique is safe, less invasive and present good outcomes in the midterm, which must be based on appropriate selection of patients(AU)

ABSTRACT

Objetivo: Avaliar a adesão das mulheres com câncer cervical às orientações de autocuidado relacionadas à braquiterapia. Método: Estudo longitudinal, realizado em um ambulatório de radioterapia na região centro-oeste, com mulheres com câncer cervical submetidas à braquiterapia. As participantes responderam ao questionário sobre adesão às orientações de autocuidado durante o tratamento. Resultados: Trinta mulheres com idade entre 22 e 76 anos participaram do estudo. Das 12 orientações, as pacientes reportaram adesão boa em seis(50%), moderada em quatro (33%), e baixa em duas (17%). Apenas sete (23%) das pacientes aderiram ao uso de dilatadores vaginais pós-braquiterapia para prevenção da estenose vaginal. Em média, as pacientes aderiram à nove das doze orientações recebidas. Conclusão: As pacientes apresentaram boa e moderada adesão para a maioria das orientações fornecidas. Sugere-se que intervenções educativas sejam implementadas para melhorar a comunicação visual e consequentemente melhorar a adesão às orientações de autocuidado em braquiterapia(AU)


Objective: to evaluate the adherence of women with cervical cancer to self-care guidelines related to brachytherapy. Method: Longitudinal study, performed in an outpatient radiotherapy clinic in the center-west region, with women with cervical cancer submitted to brachytherapy. Participants answered the questionnaire on adherence to self-care guidelines during treatment. Results: Thirty women between 22 and 76 years of age participated in the study. Of the 12 guidelines, patients reported good adherence to six (50%), moderate adherence to four (33%), and low adherence to two (17%). Only seven (23%) patients adhered to the use of postbrachytherapy vaginal dilators for prevention of vaginal stenosis. On average, the patients adhered to nine of the twelve guidelines received. Conclusion: The patients showed good and moderate adherence to most of the orientations provided. Educational interventions should be implemented to improve visual communication and consequently improve adherence to self-care guidelines in brachytherapy.(AU)

De las 12 directrices, las pacientes informaron de una buena adhesión en seis (50%), una adhesión moderada en cuatro (33%) y una baja adhesión en dos (17%). Sólo siete (23%) de las pacientes se adhirieron al uso de dilatadores vaginales después de la braquiterapia para la prevención de la estenosis vaginal. En promedio, las pacientes se adhirieron a nueve de las doce pautas recibidas. Conclusión: Las pacientes tuvieron una buena y moderada adhesión a la mayoría de las orientaciones proporcionadas. Se sugiere que se realicen intervenciones educativas para mejorar la comunicación visual y, por consiguiente, mejorar la adhesión a las directrices de autocuidado en la braquiterapia(AU)

ABSTRACT

ABSTRACT Purpose: To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit. Materials and methods: Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, deterioration of the upper tract, intraoperative blood loss and patient-reported quality of life (HRQOL). The modified Wallace 1 technique involved eversion of the ureteral plate and bowel mucosa edges, which were anastomosed together in running fashion, while the outher anastomotic wall was augmented with sero-serosal interrupted sutures. Results: The mean (SD) follow-up time was 26.1 (5.7) months in group I and 25.2 (4.8) months in group II, during which, anastomotic stricture was observed in 8 patients (12%) from the first and 2 patients (3%) from the second group (p < 0.05). The anastomotic leakage rate was significantly higher in first group (17% vs. 8.5%, p< 0.05), while patient-reported HRQOL outcomes were similar between groups after the 12 month follow-up period. Conclusions: By using a modified Wallace technique, we were able to significantly lower anastomotic stricture and anastomotic leakage rates, which are major issues in minimizing both short- and long-term postoperative complications.

ABSTRACT

Resumen: Presentamos la primera experiencia en Uruguay de una biopsia endobiliar con pinza por acceso percutáneo que realizáramos en una paciente con estenosis biliar hiliar de probable causa neoplásica. Hasta nuestro conocimiento, no existen reportes de esta técnica en Uruguay. La difusión de la disponibilidad de esta técnica en nuestro medio es de gran importancia, ya que permite al equipo médico tratante disponer de una nueva herramienta para el manejo diagnóstico de las estenosis biliares.


Abstract: The study presents the first experience in Uruguay of a forceps biopsy of biliary ducts via percutaneous catheterization performed in a patient with hilar biliary strictures probably caused by a tumor. As far as we know, no reports on this technique have been published in our country. It is important to spread the availability of this technique in our country since it provides the medical team with a new tool for the diagnostic handling of biliary strictures.


Resumo: Apresentamos a primeira experiência no Uruguai de uma biópsia endobiliária com pinça de acesso percutânea realizada em um paciente com estenose biliar hilar de provável causa neoplásica. Para nosso conhecimento, não há relatos dessa técnica no Uruguai. A difusão da disponibilidade dessa técnica em nosso ambiente é de grande importância, pois permite à equipe médica responsável o tratamento ter uma nova ferramenta para o manejo diagnóstico da estenose biliar.

ABSTRACT

Intussusception is a medical condition, in which a proximal part of the intestine folds into the distal intestine. Adult intussusceptions are rare and account for approximately 5% of all cases of intussusceptions. The anatomical leading points include tumors, diverticulums, polyps, and strictures in 80-90% of adult intussusceptions, and 65% of colon intussusceptions and 30% of small bowel intussusceptions originate from malignant tumors. Treatments for adult intussusception have not been established, but most cases require surgical treatment. The gastrointestinal tract is the most common extranodal site for non-Hodgkin lymphoma. The symptoms are mostly non-specific, but they rarely lead to complications, such as bleeding, perforation, and intussusception. Furthermore, few cases of primary gastrointestinal lymphomas causing intussusception have been reported. This paper reports a case of small bowel diffuse large B cell lymphoma that caused ileocolic intussusception in a 69-year-old woman with no medical history. She underwent a small bowel resection and received six cycles of adjuvant chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone. Since then, she has been in complete remission.

ABSTRACT

Coronary computed tomography angiography (CCTA) is a well-validated and noninvasive imaging modality for the assessment of coronary artery disease (CAD) in patients with stable ischemic heart disease and acute coronary syndromes (ACSs). CCTA not only delineates the anatomy of the heart and coronary arteries in detail, but also allows for intra- and extraluminal imaging of coronary arteries. Emerging technologies have promoted new CCTA applications, resulting in a comprehensive assessment of coronary plaques and their clinical significance. The application of computational fluid dynamics to CCTA resulted in a robust tool for noninvasive assessment of coronary blood flow hemodynamics and determination of hemodynamically significant stenosis. Detailed evaluation of plaque morphology and identification of high-risk plaque features by CCTA have been confirmed as predictors of future outcomes, identifying patients at risk for ACSs. With quantitative coronary plaque assessment, the progression of the CAD or the response to therapy could be monitored by CCTA. The aim of this article is to review the future directions of emerging applications in CCTA, such as computed tomography (CT)-fractional flow reserve, imaging of vulnerable plaque features, and quantitative plaque imaging. We will also briefly discuss novel methods appearing in the coronary imaging scenario, such as machine learning, radiomics, and spectral CT.
