Bleeding duodenal diverticula managed With surgical resection: A case report

@#The duodenum is the most common extra-colonic site of diverticulum. If present, it rarely manifests with symptoms or complications. A case is discussed involving a 78-year-old female who presented with massive upper gastrointestinal bleeding from duodenal diverticula. Due to hemodynamic instability, she eventually underwent duodenal resection, with a side-to-side duodenojejunostomy as a means of restoring intestinal continuity. The postoperative course was unremarkable. The patient was able to feed enterally and had no recurrence of bleeding.

Safety and efficacy of arteriovenous fistula angioplasties performed by nephrologists: report from a Brazilian interventional nephrology center / Segurança e eficácia de angioplastias de fístulas arteriovenosas realizadas por nefrologistas: relato de um centro de nefrologia intervencionista brasileiro

ABSTRACT Introduction: Arteriovenous fistulas (AVF) are the first choice vascular access for hemodialysis. However, they present a high incidence of venous stenosis leading to thrombosis. Although training in interventional nephrology may improve accessibility for treatment of venous stenosis, there is limited data on the safety and efficacy of this approach performed by trained nephrologists in low-income and developing countries. Methods: This study presents the retrospective results of AVF angioplasties performed by trained nephrologists in a Brazilian outpatient interventional nephrology center. The primary outcome was technical success rate (completion of the procedure with angioplasty of all stenoses) and secondary outcomes were complication rates and overall AVF patency. Findings: Two hundred fifty-six angioplasties were performed in 160 AVF. The technical success rate was 88.77% and the main cause of technical failure was venous occlusion (10%). The incidence of complications was 13.67%, with only one patient needing hospitalization and four accesses lost due to the presence of hematomas and/or thrombosis. Grade 1 hematomas were the most frequent complication (8.2%). The overall patency found was 88.2 and 80.9% at 180 and 360 days after the procedure, respectively. Conclusion: Our findings suggest that AVF angioplasty performed by trained nephrologists has acceptable success rates and patency, with a low incidence of major complications as well as a low need for hospitalization.

RESUMO Introdução: As fístulas arteriovenosas (FAV) são a primeira escolha de acesso vascular para hemodiálise. No entanto, elas apresentam uma alta incidência de estenoses venosas levando à trombose. Embora o treinamento em nefrologia intervencionista possa melhorar a acessibilidade para o tratamento das estenoses venosas, há dados limitados sobre a segurança e a eficácia desta abordagem realizada por nefrologistas treinados em países em desenvolvimento e de baixa renda. Métodos: Este estudo apresenta os resultados retrospectivos de angioplastias de FAV realizadas por nefrologistas treinados em um centro ambulatorial brasileiro de nefrologia intervencionista. O desfecho primário foi a taxa de sucesso técnico (conclusão do procedimento com angioplastia de todas as estenoses) e os desfechos secundários foram taxas de complicação e a patência geral das FAV. Achados: Duzentas e cinquenta e seis angioplastias foram realizadas em 160 FAV. A taxa de sucesso técnico foi de 88,77% e a principal causa de falha técnica foi a oclusão venosa (10%). A incidência de complicações foi de 13,67%, com apenas um paciente necessitando de internação e quatro acessos perdidos devido à presença de hematomas e/ou trombose. Hematomas de grau 1 foram a complicação mais frequente (8,2%). A patência geral encontrada foi de 88,2 e 80,9% a 180 e 360 dias após o procedimento, respectivamente. Conclusão: Nossos achados sugerem que a angioplastia de FAV realizada por nefrologistas treinados tem taxas de sucesso e patência aceitáveis, com uma baixa incidência de complicações maiores, bem como uma baixa necessidade de hospitalização.

Impacto del confinamiento por la pandemia COVID-19 en el dolor musculoesquelético y la calidad de vida / Impact of COVID-19 pandemic confinement on musculoskeletal pain and quality of life

Resumen: Introducción: En Marzo de 2020 se estableció el confinamiento en España debido a la pandemia por COVID-19. El objetivo de este estudio es determinar su impacto en el dolor y la calidad de vida de personas con dolor osteomuscular. Material y métodos: Estudio prospectivo que incluyó 490 personas agrupadas en: 140 personas sin dolor (grupo 1), 140 personas con dolor osteomuscular, pero sin patología diagnosticada (grupo 2), 140 pacientes con patología musculoesquelética (grupo 3) y 70 pacientes en lista de espera quirúrgica (LEQ) por patología musculoesquelética (grupo 4). Se recogieron datos sobre el dolor, la actividad física y la calidad de vida (EuroQol-5D) al inicio del confinamiento y un año después. Resultados: La edad media fue de 53 ± 17.5 años (18-88) y 51.3% fueron mujeres. Las personas en LEQ refirieron un dolor significativamente mayor que el resto de grupos (p < 0.001) con una puntuación en la escala visual analógica del dolor de 6.3 ± 1.9. Los grupos 3 y 4 sufrieron un aumento significativo de su dolor desde 2020 hasta 2021 (p < 0.001), mientras que en el grupo 2 disminuyó (p < 0.001). El consumo de analgésicos creció de 2020 a 2021 (39.9% versus 44.3%, p = 0.007); 70.2% sufrió un empeoramiento en alguna de las dimensiones del EuroQol-5D, siendo el grupo en LEQ el más afectado (p < 0.001). Conclusiones: El confinamiento ha producido en pacientes con patología musculoesquelética un empeoramiento del dolor y de calidad de vida mayor que en el resto de personas, especialmente en aquéllas en espera de cirugía, traduciéndose en un aumento del consumo de analgésicos.

Abstract: Introduction: In March 2020, lockdown was established in Spain because of the COVID-19 pandemic. The aim of this study is to assess its impact on pain and quality of life in patients with musculoskeletal pain. Material and methods: Prospective study including 490 individuals grouped in: 140 people without pain, 140 people with musculoskeletal pain but without any related pathology diagnosed, 140 patients diagnosed for a musculoskeletal condition and 70 patients in surgical waiting list (SWL) for a musculoskeletal condition. Data regarding pain, physical activity and quality of life (EuroQol-5D) was collected at the beginning of lockdown and one year after (March 2021). Results: Mean age was 53 ± 17.5 years old (18-88) and 51.3% were women. Patients in SWL referred significantly more pain than the rest of groups (p < 0.001), with a score in the visual analogue scale of 6.3 ± 1.9. Groups 3 and 4 suffered a significant increase of their pain from 2020 to 2021 (p < 0.001), while decreasing in group 2 (p < 0.001). Analgesics intake grew from 2020 to 2021 (39.9% versus 44.3%, p = 0.007). 70.2% experienced a worsening of at least one dimension of EuroQol-5D over last year, with patients in SWL being the most affected (p < 0.001). Conclusion: Lockdown has caused in patients with musculoskeletal conditions a greater aggravation of pain and deterioration of quality of life than in the general population, especially in patients in SWL, translating in an increase in analgesics intake.

Simulación Mediante Elemento Finito de Sistemas Intramedulares Telescópicos para Rehabilitación de Pacientes con Osteogénesis Imperfecta / Simulation by Finite Element Method of Intramedullary Telescopic Systems for Rehabilitation of Patients with Osteogenesis Imperfecta

Resumen En el trabajo se plantea el análisis de diferentes geometrías para un dispositivo intramedular, las cuales ayudan a reducir y evitar la migración, deformación y rotura del implante en tejido óseo afectado con Osteogénesis Imperfecta (OI). Se realizaron diseños en CAD de diferentes prototipos, donde se analizan las propiedades mecánicas en el alma del dispositivo, así como en las roscas distal y proximal de los implantes macho y hembra. Asimismo, se obtuvieron modelos 3D de huesos de un infante afectado con OI para realizar simulaciones mediante elemento finito de la interacción entre el hueso y el dispositivo intramedular. Los resultados muestran que los prototipos propuestos disminuyen la deformación del dispositivo, así como el aumento en la rigidez de la relación hueso-prótesis. Asimismo, las roscas generaron un menor esfuerzo en la unión con el hueso, lo que prevé un menor daño al tejido óseo. El trabajo se limitó al análisis numérico del rediseño de implantes telescópicos intramedulares para afectados con OI. Concluyendo que la geometría semicircular 3/4 de caña, otorga un óptimo resultado en las pruebas realizadas, al tiempo que las roscas ACME proveen una mejor sujeción en las epífisis distal y proximal de los huesos largos.

Abstract In this work we propose the analysis of different geometries for an intramedullary device, which help to reduce and avoid the migration, deformation and rupture of the implant in bone tissue affected with Osteogenesis Imperfecta (OI). Designs of different prototypes were made in CAD, where the mechanical properties in the device's soul are analyzed, as well as in the distal and proximal threads of the male and female implants. Likewise, 3D bone models of an affected infant with OI were obtained to perform finite element simulations of the interaction between the bone and the intramedullary device. The results show that the prototypes proposed decrease the strain of the device, as well as the increase in the stiffnes of the bone-prosthesis relationship. Also, the threads generated less stress in the union with the bone, which provides less damage to the bone tissue. The work was limited to the numerical analysis of the redesign of intramedullary telescopic implants for patients with OI. Concluding that the semicircular geometry 3/4 of cane, gives an optimal result in the tests carried out, while the ACME threads provide a better subjection in the distal and proximal epiphyses of the long bones.

Solitary fibrous tumor of the kidney: a report of two cases / Tumor fibroso solitário do rim: relato de dois casos

ABSTRACT Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm, composed of monotonous spindle cells, intermingled with collagen fibers. Kidney location is sporadic, with few reports in literature. We present two cases of 40- and 48-year-old males, one with incidental detection of a peripheral mass; another with hilar lesion perceived following investigation of hematuria. Both revealed a spindle-cell proliferation, without mitosis and necrosis. Immunohistochemical studies: positivity for CD34, CD99 and B-cell lymphoma 2 (Bcl-2). No sign of disease were evident nine and five months after surgery, respectively. SFT is mostly benign, but can show malignant behavior. Morphologic and immunohistochemical characteristics are essential for diagnosis.

Invasive bladder urothelial carcinoma, plasmacytoid variant: case report / Carcinoma urotelial invasor de bexiga, variante plasmocitoide: relato de caso

ABSTRACT Invasive bladder urothelial carcinoma, plasmacytoid variant is a rare entity with scarce cases reported in the literature. We report a case of a 79 years old male, subjected to transurethral resection of bladder tumor, which histological examination revealed a pT1 high-grade urothelial carcinoma. Subsequently, he underwent radical cystoprostatectomy, which showed urothelial carcinoma with lack of cohesion, plasmacytoid variant, positive for citokeratin 7 (CK7), citokeratin 20 (CK20) and trans-acting T-cell-specific transcription factor (GATA-3), and negative for E-cadherin and CD138. It is important to recognize the plasmacytoid variant of the invasive urothelial carcinoma, since it avoids a potential misdiagnosis of metastatic cancer.

RESUMO Carcinoma urotelial invasor da bexiga, variante plasmocitoide, é uma entidade rara, com poucos casos descritos na literatura. Relatamos o caso de um homem, 79 anos, submetido à resseção transvesical de tumor da bexiga, cuja histologia revelou carcinoma urotelial de alto grau pT1. Posteriormente, foi submetido à cistoprostatectomia radical, que mostrou carcinoma urotelial invasor, descoeso, de tipo plasmacitoide, positivo para citoqueratina 7 (CK7), citoqueratina 20 (CK20) e fator de transcrição de ação"trans" específico de células T (GATA-3) e negativo para E-caderina e CD138. É importante reconhecer a variante plasmocitoide do carcinoma urotelial invasor, uma vez que se evita potencial diagnóstico errado de doença metastática.

Persistent disorders of mineral metabolism after one year of kidney transplantation / Alterações do metabolismo mineral e ósseo após um ano de transplante renal

Abstract Introduction: The persistence of mineral metabolism disorders after renal transplant (RT) appears to possess a negative impact over graft and patient's survival. Objectives: To evaluate the parameters of mineral metabolism and the persistence of hyperparathyroidism (HPT) in transplanted patients for a 12-month period after the procedure. Methods: Retrospective analysis of 41 transplants (18 women- 44%, mean age of 39 ± 15 years) performed in a University Hospital, evaluating changes of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) and the prevalence of persistent HPT. The patients were divided into two groups accordingly to PTH levels prior to Tx: Group 1 with PTH ≤ 300 pg/mL (n = 21) and Group 2 with PTH > 300 pg/mL (n = 20). The persistency of HPT after transplant was defined as PTH ≥ 100 pg/mL. The evolution of biochemical parameters and the persistency of HPT were analyzed in each group after 1 year of transplant. Results: After a one-year of follow up, 5% of the patients presented hypophosphatemia (p < 2.7 mg/dL), 24% hypercalcemia (Ca > 10.2 mg/dL) and 48% persistency of HPT (PTH ≥ 100 pg/mL). There was a positive correlation between the PTH pre and post Tx (r = 0.42/p = 0.006) and a negative correlation between PTH and Ca pre-Tx (r = -0.45/p = 0.002). However, there was no significant difference among groups 1 and 2 regarding PTH levels pre and post Tx. Conclusion: The findings in this article suggest that mineral metabolism alterations and the persistency of HPT may occur after one year of renal Tx, mainly in patients which present high PTH levels prior toTx.

Resumo Introdução: A persistência de distúrbios do metabolismo mineral ósseo após o transplante renal (Tx) parece possuir um impacto negativo sobre a sobrevida do enxerto e do paciente. Objetivos: avaliar os parâmetros do metabolismo mineral e a persistência de hiperparatiroidismo (pHPT) 12 meses após o Tx. Métodos: Análise retrospectiva de 41 transplantes (18 mulheres- 44%, idade de 39 ± 15 anos) realizados em um Hospital Universitário, avaliando cálcio (Ca), fósforo (P), hormônio da paratireóide (PTH) e a prevalência de pHPT. Pacientes foram divididos em dois grupos de acordo com os níveis de PTH pré Tx: Grupo 1: PTH ≤ 300 pg/ml (n = 21) e Grupo 2: PTH > 300 pg/ml (n = 20). pHPT foi definida como PTH ≥ 100pg/mL após o Tx. A evolução dos parâmetros bioquímicos e a pHPT foram analisadas após 1 ano de Tx. Resultados: após um ano, 5% dos pacientes apresentaram hipofosfatemia (p < 2,7mg/dL), 24% hipercalcemia (Ca > 10,2 mg/dL) e 48% persistência de HPT (PTH ≥ 100 pg/mL ). Houve correlação positiva entre PTH pré e pós Tx (r = 0,42/p = 0,006) e correlação negativa entre PTH e Ca pré-Tx (r = -0,45/p = 0,002). Entretanto, não houve diferença significativa entre os grupos 1 e 2 em relação aos níveis de PTH pré e pós-Tx. Conclusão: Os resultados sugerem que alterações do metabolismo mineral e a pHPT podem ocorrer após um ano do Tx, principalmente em pacientes com níveis elevados de PTH pré-Tx.

Flora fúngica no ambiente da Unidade de Terapia Intensiva Pediátrica e Neonatal em hospital terciário / Environmental fungal flora in Pediatric and Neonatal Intensive Care Units at a tertiary hospital

OBJETIVO: As infecções nosocomiais são responsáveis por morbidade e mortalidade significativas no período neonatal. Considerando-se a preocupação com a qualidade do ar de áreas críticas como Unidades de Terapia Intensiva (UTI), foi realizado um levantamento da flora fúngica das UTI Pediátrica e Neonatal do Hospital das Clínicas Samuel Libânio, Pouso Alegre (MG), com a finalidade de identificar a presença de fungos potencialmente patogênicos e oportunistas. MÉTODOS: Foram realizadas 30 coletas, que incluíram leitos, incubadoras, janelas, aparelhos de ar condicionado, telefone, estetoscópios, portas e maçanetas. Placas de Agar Sabouraud Dextrose com o material das coletas foram incubadas em temperatura ambiente por 15 dias. A identificação foi baseada nas características macroscópicas no exame direto e em microcultivos. RESULTADOS: Fungos potencialmente patogênicos e toxigênicos foram isolados. A análise quantitativa das colônias revelou a presença de 11 gêneros. Verificou-se que mais de 40 por cento das colônias correspondem ao gênero Penicillium spp, seguido por Cladosporium spp e Chrysosporium spp. CONCLUSÕES: Os fungos encontrados podem apresentar grande potencial de patogenicidade, principalmente em imunodeprimidos. É importante adotar medidas de controle ambiental, como assepsia dos equipamentos, controle da presença de visitantes, lavagem das mãos pelos funcionários e troca de filtros de ar condicionado.

OBJECTIVE: Nosocomial infections lead to significant morbidity and mortality in the neonatal period. Considering the concern regarding air quality in critical hospital areas, such as Intensive Care Units (ICU), this study aims to identify the presence of potentially pathological fungi in the Pediatric and Neonatal Intensive Care Unit of the Samuel Libânio Hospital in Pouso Alegre, Minas Gerais, Brazil. METHODS: Thirty samples were collected in the following areas: surface of beds, incubators, windows, air conditioning, telephones, stethoscopes, doors and door knobs. Petri dishes of Sabouraud Dextrose Agar with the collected samples were incubated at air temperature for 15 days. The identification was based on macroscopic and microscopic characteristics and subcultures. RESULTS: Potentially pathological and toxigenic fungi were isolated in the studied areas. The quantitative analysis revealed the presence of 11 genera: 40 percent of the colonies were Penicillium spp., followed by Cladosporium spp. and Chrysosporium spp. CONCLUSIONS: The fungi found may present a great pathogenic potential, mainly in immunocompromised patients. It is important to adopt some measures in order to reduce nosocomial infection in ICU, such as the strict control regarding equipment cleansing, control of visitors, hand washing and periodic cleansing and renewal of air conditioning filters.

Perfil de pacientes diabéticos em diálise / Profile of diabetic patients in dialysis

Introdução: Atualmente, diabetes mellitus (DM) representa a principal causa mundial de doença renal crônica. No Brasil, aproximadamente 25% dos pacientes em diálise são diabéticos. Objetivo: Este estudo visa a determinar as características clínicas e sociais dos pacientes diabéticos em diálise na cidade de Curitiba, Brasil. Materiais e Métodos: Estudo transversal realizado no período de março a agosto de 2006 na nossa instituição. Foram identificados 97 pacientes diabéticos (46% mulheres; média de 9,4 anos). As informações clínicas e socioeconômicas dos pacientes com idade de ± 58 anos foram obtidas por meio de questionário e revisão de prontuário. Resultados: Hipertensão arterial sistêmica (HAS) foi relatada por 75% dos pacientes e o tabagismo, em 25% das respostas. Renda familiar e nível de escolaridade baixos foram verificados em 85% dos pacientes (1 a 5 salários mínimos/mês). O diagnóstico de DM foi realizado por médico clínico geral em 86% dos casos, e o intervalo entre o diagnóstico de DM e a referência para o nefrologista foi maior que 10 anos (80%). Observou-se também que 48% e 70% dos pacientes em diálise já tinham avaliação prévia, por um endocrinologista e oftalmologista, respectivamente. Entretanto, somente 9% e 35% ainda mantêm acompanhamento regular com esses profissionais. Finalmente, 65% dos pacientes nunca receberam informações sobre cuidados do pé diabético. Conclusão: Diabéticos em diálise apresentam baixa escolaridade e maior prevalência de HAS. Além disso, o treinamento e acompanhamento de uma equipe multidisciplinar poderiam melhorar os cuidados dos pacientes diabéticos em diálise.

Introduction: Currently, diabetes mellitus (DM) represents the main cause of chronic disease worldwide. In Brazil, approximately 25% of dialysis patients are diabetic. Objective: This study was performed to determine the clinical and social characteristics in diabetic dialysis patients in the city of Curitiba, Brazil. Material and Methods: A cross-sectional study was carried out in our institution between March and August 2006. Ninety-seven diabetic (46% female: mean age 58 ± 9.4) patients were identified. Clinical and socialeconomic information was assessed through a questionnaire and by files review. Results: Systemic hypertension (High Blood Pressure HBP) was reported by 75% of patients, and smoking habit was present in 25% of the answers. Low income and low schooling were verified in 85% of the patients (between 1 and 5 minimal wage/month). Moreover, the DM diagnosis was performed by a general physician in 86% of the cases, and the interval between DM diagnosis and referral to the nephrologist was more than 10 years (80%). It has also been observed that 48% and 70% of the patients during dialysis had a previous evaluation by endocrinologist and ophthalmologist, respectively. However, only 9% and 35% of them are still being followed by these professionals regularly. Finally, 65% of the patients never received any information about diabetic foot care. Conclusion: Diabetic patients on dialysis have low income and schooling, with an increased prevalence of HBP. Moreover, management and training of a multiprofessional team could lead to an improvement in diabetes care in diabetic patients on regular dialysis.

Impacto del margen nodal en la sobrevida de pacientes con cáncer colónico en estadío local y locorregional / Nodal margin impact on the survival of patients with colonic cancer in local and loregional stage

Objetivo: Analizar la sobrevida específica libre de enfermedad según la extensión de la disección ganglionar en pacientes intervenidos con intención curativa por cáncer de colon. Pacientes y Métodos: Entre enero de 2001 y diciembre de 2006 se realizaron 189 cirugías programadas por cáncer de colon con intención curativa en el Sector de Coloproctología del Hospital Santojanni. 141 pacientes conforman el grupo que se analiza en este trabajo. En todos los casos un miembro del Equipo de Coloproctología participó como cirujano o asistente. Las piezas quirúrgicas fueron analizadas por el mismo anatomopatólogo junto a su equipo. La evolución postoperatoria alejada de los pacientes incluidos en el estudio se determinó por consulta personal y/o telefónica. Los datos fueron recolectados en fichas específicas diseñadas para la finalidad del trabajo. Resultados: El promedio de ganglios aislados por pieza fue de 9,7 con un rango de 0-25. La sobrevida libre de enfermedad de los pacientes en estadío I/II con resecciones con 12 ó más ganglios aislados en la pieza demostró ser significativamente superior al grupo con menos de 12 (p = 0,005). La sobrevida libre de enfermedad de los pacientes en estadío III con 1-3 ganglios comprometidos fue significativamente mayor que el grupo con 4 o más (p = 0,047). Conclusiones: Una mayor extensión de disección nodal se relacionaría con un incremento en la sobrevida específica por enfermedad en pacientes intervenidos por cáncer de colon estadío I/II.

Objective: To determine the impact of nodal margin on the specific free disease survival of patients operated of colon cancer with curative intentions. Patients and Methods: From January 2001 to December 2006, 189 patients were surgically treated of colon cancer in our institution. 141 patients were included in our study. In all the cases a colorectal surgeon of our staff participates in the procedure. The surgical specimens were analyzed by the same pathologist in all the cases. Long term outcome of the patients was assessed by personal interview or phone interview. The data was recorded in a specific form designed for the study. Results: The average of lymph nodes harvested by specimen was 9, 7 (range: 0-25). Specific free disease survival in patients' stage I/II with more than 12 nodes harvested was statistically superior respect the same group with less than 12 nodes (p = 0,005). Specific free disease survival in patients stage III with 3 or less positive lymph no des was statistically superior respect the same group with 4 o more positive lymph nodes (p = 0,047). Conclusions: A major nodal margin extension is associated with an improvement in the specific disease free survival in patients operated of colon cancer in stage I/II.

Pacientes y Métodos: Entre Enero de 2001 y Diciembre de 2006 se realizaron 189 cirugías electivas por cáncer de colon en el Sector de Coloproctología de nuestro hospital; 141 pacientes se analizan en este trabajo, 54 por ciento de sexo masculino, con una edad promedio de 67,2 (28-87) años. Las variables estudiadas fueron edad, sexo, localización, grado de diferenciación celular, penetración tumoral, carácter mucinoso, crecimiento y estadío tumoral. Dichos factores se compararon entre pacientes con ganglios metastásicos y sin metástasis ganglionares. La técnica quirúrgica se realizó según las normativas actuales. Las piezas fueron analizadas por el mismo equipo de anatomopatólogos. Resultados: Los pacientes con metástasis ganglionares representaron el 42,5 por ciento (60). La asociación de distintas variables con la presencia de metástasis ganglionares fue significativa para la presencia de componente mucinoso (p=0,002), bajo grado de diferenciación celular (p=0,000) y mayor penetración tumoral (p=0,0004). El análisis de regresión mostró para los tumores mucinosos OR=3.7 (IC 95 per cent: 1,53-8,9), con mayor profundidad de penetración OR=4.69 (IC 95 per cent: 1,9-11) y bajo grado de diferenciación OR=8.18 (IC 95 per cent: 2,8-23,3). Conclusión: La presencia de componente mucinoso, bajo grado de diferenciación celular y la mayor penetración tumoral demostraron ser factores de riesgo asociados a la presencia de ganglios positivos en la pieza.

Objective: To analyze the association between clinic and pathologic variables with the presence of positive lymph nodes in patients operated of colon cancer. Patients and Methods: From January 2001 to December 2006, 189 elective surgeries for colon cancer were done at our institution; 141 patients were analyzed in this study, 54 per cent males, average age was 67,2 (28-87) years. The variables included were age, sex, localization, cytologic degree, tumor penetration, mucinous component, type of growth and tumor stage. Those variables were compared between patients with lymph nodes metastases and without it. Surgery procedure was accorded to actual guidelines. Tumour specimens were studied by the same group of pathologiest. Results: Patients with lymph nodes metastases represents 42,5 per cent (60). The variables association with the presence of positive lymph nodes in the specimen showed statistic significance for mucinous component (p=0,002), low cytologic differentiation (p=0,000) and deepest wall penetration (p=0,0004). Unilogistic regression demonstrated an OR=3.7 (IC 95 per cent: 1,53-8,9) for mucinous tumours, OR=4.69 (IC 95 per cent: 1,9-11) for deepest wall penetration and OR=8.18 (IC 95 per cent: 2,8-23,3) for low cytologic degree of differentiation. Conclusion: The presence of extensive mucinous component, low cytologic degree of differentiation and deepest wall penetration represents risk factors for positive lymph nodes in the tumour specimen.

Tratamiento de hemorroides sintomáticas grado III y IV mediante macroligadura elástica como práctica de consultorio / Office treatment of advanced symptomatic hemorrhoidal disease using macro banding technique

Introducción: La enfermedad hemorroidal es frecuente en nuestro medio. Existen diversos métodos para controlar sus síntomas, incluyendo la colocación de bandas elásticas que se reserva para hemorroides grado II y III poco voluminosas sangrantes. En hemorroides grado III-IV la resolución suele ser quirúrgica requiriendo anestesia, internación y habitualmente poco confortable para el paciente. Objetivo: Determinar la factibilidad del tratamiento ambulatorio de hemorroides grado III y IV mediante la aplicación de macroligaduras elásticas. Pacientes y Métodos: Entre Febrero y Junio de 2008 se evaluaron 82 pacientes tratados en consultorio mediante macroligadura de hemorroides sintomáticas avanzadas. El procedimiento se realizó en consultorio, bajo anestesia local, hasta 3 bandas en forma simultánea y los controles a las 72 horas, 7º, 14º, y 21º días. Resultados: Se trataron dos y tres paquetes en el 50 y 17 por ciento de casos. La tolerancia al procedimiento fue buena en el 83 por ciento. El tiempo promedio fue 12.7 minutos. 34 por ciento refirió dolor leve en las 72 horas asociado a hipertonía esfinteriana (p<0.000) y paquetes mayores o iguales a 2 cm3 (p=0.04). 25.6 por ciento de los pacientes refirieron sangrado escaso en las primeras 72 horas. No se registraron complicaciones sépticas. El tiempo promedio de reinserción laboral fue 2,24 (r= 0.5-6) días. Conclusiones: El tratamiento ambulatorio de la enfermedad hemorroidal avanzada mediante macroligadura elástica en consultorio es seguro, confortable y permite una rápida reinserción laboral.

Background: Hemorrhoidal disease is very frequent. For the control of symptoms, diverse methods have been developed including hemorrhoids banding in grade II-III not voluminous and with bleeding as principal symptom. Usually, in advanced (grade III and IV) disease surgical resolution is necessary, with the need of anesthesia, hospitalization, and not much comfortable for the patient. Aim: To determinate the feasibility of office ambulatory macro banding in the treatment of advanced hemorrhoidal disease (grade III-IV). Patients and methods: Eighty two patients treated with macro banding for advanced hemorrhoidal disease were evaluated between February and June from 2008. The procedure was done in the office, under local anesthesia, with simultaneous banding if necessary and with controls at 72 hours, 7º, 14º and 21º day post procedure. Results: Two and three banding was done in 50 and 17 per cent respectively. Eighty three percent referred good tolerance for the procedure. Mean time of the procedure was 12.7 minutes. In 34 per cent of patients light pain sensation was referred in the first 72 hours associated with esphinteric hypertonic (p <0.000) and the treatment of hemorrhoids bigger than 2cm3 (p 0.04). In 25.6 per cent of patients minimal bleeding was observed in to the first 72 hours. No septic complications were observed. Mean time for labor return was 2.24 (range: 0.5-6) days. Conclusion: Office ambulatory treatment of advanced hemorrhoidal disease using macro banding technique is safe, comfortable and allows a faster recover for working.
