ABSTRACT

The hemodynamic characteristics of venous reflux are associated with infertility in patients with varicocele; however, an effective method for quantifying the structural distribution of the reflux is lacking. This study aimed to predict surgical outcomes using a new software for venous reflux quantification. This was a retrospective cohort study of a consecutive series of 105 patients (age range: 22-44 years) between July 2017 and September 2019. Venous reflux of the varicocele was obtained using the Valsalva maneuver during scrotal Doppler ultrasonography before microsurgical varicocelectomy. Using this software, the colored reflux signals were segmented, and the gray scale of the color pixels representing the reflux velocity was comprehensively quantified into the mean reflux velocity of the green layer (MRVG) and the reflux velocity standard deviation of the green layer (RVSDG). Spontaneous pregnancy and changes from baseline in the semen parameters were assessed during a 12-month follow-up period. Data were analyzed using logistic regression analysis. An association of the high MRVG group with impaired progressive motility (odds ratio [OR] = 2.868, 95% confidence interval [CI]: 1.133-7.265) and impaired sperm concentration (OR = 2.943, 95% CI: 1.196-7.239) was found during multivariate analysis. High MRVG (OR = 2.680, 95% CI: 1.086-6.614) and high RVSDG (OR = 2.508, 95% CI: 1.030-6.111) were found to be independent predictors of failure to achieve pregnancy following microsurgical repair. In summary, intense venous reflux is an independent predictor of impaired progressive motility, sperm concentration, and pregnancy outcomes after microsurgical varicocelectomy.

ABSTRACT

El estudio de las venas tiroideas no ha recibido una investigación tan exhaustiva como lo tuvieron las arterias tiroideas y los nervios laríngeos en relación a la cirugía tiroidea.De los tres pedículos venosos de la glándula tiroides, el medio, de lejos es el menos estudiado. La vena tiroidea media es inconstante y es el primer elemento vascular de la glándula tiroides que debe ser seccionado antes de luxar el lóbulo hacia medial para evaluar sus relaciones posteriores. Su lesión puede provocar sangrado intraoperatorio dificultando secundariamente la identificación del nervio laríngeo inferior y las glándulas paratiroides, próximas a la misma. Se realizó un estudio descriptivo de corte transversal evaluando la pesencia, número, simetría y asociación de la vena tiroidea media con variables tales como edad y sexo del paciente, así como la hiperfuncionalidad de la glándula tiroides y la presencia del tubérculo de Zuckerkandl en 100 tiroidectomías totales llevadas a cabo en el Instituto Nacional del Cáncer y en el Servicio de Otorrinolaringología del Hospital Central del Instituto de Previsión Social del Paraguay. La prevalencia global de vena tiroidea media fue del 74 %. En el lóbulo derecho, la vena se presentó en el 60 %, mientras que en el lóbulo izquierdo en el 53 %. En el 38 % se encontró la vena en ambos lóbulos. En 4 pacientes se localizaron venas tiroideas medias dobles, en una de ellas fue bilateral. El mayor porcentaje de las venas tiroideas medias se originó en el tercio medio del lóbulo, el 72 % en el lado derecho y el 70% en el izquierdo. No se encontró asociación entre la presencia de la vena tiroidea media y la edad, sexo, estado de hiperfunción glandular, así como tampoco con la presencia del tubérculo de Zuckerkandl.


The study of the thyroid veins has not received an investigation as extensive as the thyroid arteries and laryngeal nerves did in relation to thyroid surgery. Of the three veins pedicles of the gland the middle is far the least studied. This vein is inconstant and is the first vascular element of the gland that must be sectioned before the medial lobe is dislocated to evaluate ist posterior relationships. His injury can cause intraoperative bleeding, making it difficult to identify the inferior laryngeal nerve and the parathyroid glands, proximal to it. A descriptive crossseccional study was carried aot evaluating the presence, number, symmetricity and association of the middle thyroid vein with variables such as age and sex of the patient, as well as the hyperfunctionality of the gland and the presence of the Zuckerkandl tubercle in 100 total thyroidectomies undergoing at the National Cancer Institute and the ENT Service of the Social Security Institute´s Central Hospital. The overall prevalence of the middle thyroid vein was 74%. In the right lobe the vein appeared in 60% while in the left lobe in 53 %. Double middle thyroid vein was found in 4 patients, in one of them it was bilateral. The highest percentage of the middle thyroid veins originated in the middle third of the lobe, 72 % on the right and 70% on the left side. No association was found between the presence of the vain and age and sex, the state of glandular hyperfunstion, as well as the presence of Zuckerkandl tubercle.

ABSTRACT

El linfedema es la acumulación de fluido rico en proteínas en el intersticio, secundario a anomalías en el sistema de transporte linfático. En países desarrollados se relaciona más frecuentemente al tratamiento quirúrgico del cáncer. El diagnóstico clínico y a través de técnicas de imágenes es fundamental para evaluar el estado funcional del sistema linfático. Los objetivos principales en el manejo del linfedema son limitar la morbilidad del paciente, mejorar la funcionalidad y la calidad de vida. El tratamiento quirúrgico es una alternativa cuando las medidas conservadoras ya no son suficientes. Existen procedimientos que buscan prevenir el desarrollo del linfedema y técnicas que incluye procedimientos fisiológicos (reconstructivos) y resectivos que se utilizan cuando el linfedema ya está establecido. El éxito depende de una buena elección de los pacientes y la realización de un tratamiento individualizado. A continuación se presenta una revisión en cuanto a las últimas estrategias diagnósticas y actualización en las técnicas quirúrgicas con énfasis en el tratamiento microquirúrgico.


Lymphedema is the accumulation of protein-rich fluid in the interstitium, secondary to abnormalities in the lymphatic transport system. In developed countries it is more often related to surgical treatment of cancer. The clinical diagnosis and through imaging techniques is fundamental to evaluate the functional status of the lymphatic system. The main objectives in managing lymphedema are to limit patient morbidity, improve functionality and quality of life. Surgical treatment is an option when conservative measures are no longer sufficient. There are procedures that seek to prevent the development of lymphedema, and techniques that include physiological (reconstructive) and resective procedures that are used when lymphedema is already established. Success depends on a good selection of patients and the completion of an individualized treatment. The following is a review article of the latest diagnostic strategies and update in surgical techniques with emphasis on microsurgical treatment.

ABSTRACT

When a vein segment is grafted into arterial circulation, biomechanical forces stimulate modification of its structure. This morphological adaptive response is progressive during a medium or long term and occludes the vessel lumen, leading to a graft failure. The objective of this study was to characterize the early morphological response of the vascular wall in a terminal-terminal vascular vein graft model in Wistar rats. A segment of the femoral vein was placed in the femoral circulation. An end to end microsurgical graft anastomosis technique was implemented and standardized in twenty rats. The samples were processed with histological technique to analyze the overall structure with hematoxylin and eosin, the composition of the vessel wall with Masson trichrome technique, the proliferating and smooth muscle cells were detected with immunohistochemistry (anti-PCNA, anti-actin and anti CD68) and the induction of apoptosis with TUNEL technique. The times periods studied were 1, 3 and 5 days postoperative. There is progressive increase of cell proliferation and intensity of the density detected by PCNA with its peak at postoperative day 3. Apoptosis was not evident in any of the postoperative days. Smooth muscle had no significant change in any of the time periods studied. Macrophage and leukocyte migration was evident since the first postoperative day with infiltration into the media by the 5th day. This study characterizes the morphological aspects in the early arterialization of the vascular wall in a vein graft process. These results contribute to a better understanding of the morphopathological mechanism involved in vein graft failure.


Cuando un segmento venoso es injertado dentro de la circulación arterial, se generan fuerzas biomecánicas que estimulan modificaciones en su estructura. Esta respuesta morfológica adaptativa es progresiva a mediano y largo plazo y termina por ocluir la luz del vaso, conduciendo a la falla del injerto. El objetivo de este estudio fue caracterizar la respuesta morfológica adaptativa temprana de la pared vascular en un modelo de injerto vascular venoso termino-terminal en ratas Wistar. Un segmento de la vena femoral se coloco en la circulación arterial femoral. Una anastomosis del injerto microquirúrgica termino-terminal fue implementada y estandarizada en veinte ratas. Las muestras se procesaron con la técnica histológica para analizar su estructura general con la tinción de hematoxilina y eosina, la composición de la pared vascular con la técnica de tricromico de Masson , la proliferación y las células de musculo liso fueron detectadas mediante técnicas inmunohistoquimicas (anti PCNA, anti-actina y anti CD68) y la inducción de la apoptosis mediante la técnica de TUNEL. Los tiempos de estudio fueron al día 1, 3 y 5 postoperatorios. Hay un incremento progresivo en la proliferación celular y la intensidad de la densidad detectado mediante PCNA con un pico en el día 3 postoperatorio. La apoptosis no fue evidente en ninguno de los días postoperatorios. Las células de musculo liso no tuvieron un cambio significativo en ninguno de tiempos de estudio. La migración de macrófagos y leucocitos fue evidente desde el primer día postoperatorio con infiltración a la túnica media al 5to día. Conclusiones. Este estudio caracteriza los aspectos morfológicos en el proceso de arterialización temprana de la pared vascular en un injerto venoso. Estos resultados contribuyen al mejor entendimiento de los mecanismos morfopatológicos envueltos en la falla del injerto venoso.

ABSTRACT

Purpose: To study the effect of high grade varicocele treatment in infertile patients. Materials and Methods: Seventy-five patients were selected by the following criteria: infertility persisting for more than 1 year; abnormal semen parameters; no other infertility-related disease; no obvious causes of infertility in the subject’s partner; basal eco-color Doppler ultrasound demonstrating continuous reflux in the spermatic vein. All patients considered for the study had at least a six months period from the diagnosis to the surgery due to waiting list, choice of the patient or time needed to complete diagnostic evaluation of the couple. The surgical procedure was performed through an inguinal approach. All enrolled patients were counseled to have unprotected intercourse during the ovulation period in order to maximize the probability of pregnancy within the 6-month preoperative period. The achievement of pregnancy and semen parameters were recorded during the preoperative and postoperative period. Results: Two of the seventy-five patients were excluded because of persistent varicocele after surgery. The preoperative pregnancy rate was 1.3% (1 couple). The postoperative pregnancy rate was 42.5%. The stratification of pregnancies by semester showed a significantly higher rate in the first postoperative period (p = 0.0012). Mean time to conception was 13.5 months. Mean preoperative sperm count was 17.6x10 6 /mL compared to 19.7x10 6 /mL in the postoperative period (p < 0.0001). Mean percentage of progressive sperm motility was 13.7%, compared to 17.6% in the postoperative period (p < 0.0001). Mean percentage of normal sperm morphology was 7.6%, compared to 15.2% postoperatively (p < 0.0001). Conclusion: Surgical treatment of high grade varicocele proved to effectively treat associated infertility by improving seminal parameters and pregnancy rate in our patient cohort. .

ABSTRACT

RACIONAL: Na esquistossomose mansônica na forma hepatoesplênica ocorre fibrose hepática difusa que associada à congestão venosa do sistema porta resulta em hepatoesplenomegalia. Pode produzir hemorragia digestiva alta por rotura das varizes de esôfago e do estômago ou lesões pépticas da mucosa gastroduodenal. OBJETIVO: Estudar os efeitos da esplenectomia e ligadura da veia gástrica esquerda sobre a hemodinâmica portohepática. MÉTODO: Vinte e três portadores de esquistossomose mansônica na forma hepatoesplênica foram estudados prospectivamente, antes e cerca de duas semanas após a operação, através de estudos angiográficos dos diâmetros da artéria hepática comum e própria, artéria esplênica, artéria mesentérica superior, veia porta, veia mesentérica superior e veia gástrica esquerda. Foram aferidas as pressões da veia cava inferior, venosa central, da veia hepática livre, da veia hepática ocluída e sinusoidal. RESULTADOS: A ligadura da veia gástrica esquerda determinou acréscimo significante nas seguintes variáveis: diâmetros da artéria hepática comum e própria; diâmetro da veia mesentérica superior; o acréscimo não foi significante nas seguintes medidas: pressão venosa central e diâmetro da artéria mesentérica superior. Ela promoveu decréscimo não significante nas variáveis: pressão da veia cava inferior; pressão da veia hepática livre; pressão da veia hepática ocluída; pressão sinusoidal; diâmetro da veia porta. CONCLUSÃO: A ligadura da veia gástrica esquerda, na maioria dos casos, não determina alterações hemodinâmicas significantes do sistema porta capazes de quebrar o equilíbrio hemodinâmico funcional, que caracteriza a esquistossomose mansônica na forma hepatoesplênica.


BACKGROUND: In hepatosplenic schistosomiasis occurs diffuse hepatic fibrosis associated with venous congestion of the portal system resulting in hepatosplenomegaly. It can produce digestive hemorrhage caused by rupture of esophageal and stomach varices or peptic gastroduodenal mucosal lesions. AIM: To study the effects of splenectomy and ligature of the left gastric vein on portohepatic hemodynamics. METHOD: Twenty-three patients with hepatosplenic schistosomiasis mansoni were studied before and about two weeks after operation through angiographic diameter of the common and proper hepatic artery, splenic artery, superior mesenteric artery, portal vein, superior mesenteric vein and left gastric vein. The pressures of the inferior vena cava and central venous pressure, free hepatic vein, the hepatic sinusoidal and occluded vein were measured. RESULTS: The splenectomy and ligature of the left gastric vein determined low morbidity and null mortality. It determined significant addition to the following variables: diameters of the common and proper hepatic artery; diameter of the superior mesenteric vein. It determined non significant increase on the following measurements: right atrial pressure and diameter of the superior mesenteric artery. It determined non significant decrease to the following variables: inferior vena cava pressure; free hepatic vein pressure; occluded hepatic vein pressure; sinusoidal pressure, diameter of the portal vein. CONCLUSION: Splenectomy and ligature of the left gastric vein do not determine portal hemodynamic changes capable of breaking the functional hemodinamic balance that characterizes the hepatosplenic mansoni schistosomiasis.

ABSTRACT

RACIONAL: A esquistossomose mansônica afeta 200 milhões de pessoas em 70 países do mundo. Estima-se que 10% dos infectados evoluirão para a forma hepatoesplênica e, destes, 30% progredirão para hipertensão portal e varizes esofagogástricas, cuja expressão será através de hemorragia digestiva com mortalidade relevante no primeiro episódio hemorrágico. Múltiplas técnicas cirúrgicas foram desenvolvidas para prevenir o ressangramento. OBJETIVO: Avaliar o perfil evolutivo das varizes esofágicas após esplenectomia + ligadura da veia gástrica esquerda associada à escleroterapia endoscópica na hipertensão portal esquistossomótica. MÉTODO: Estudo prospectivo, observacional, de pacientes esquistossomóticos com antecedentes de hemorragia digestiva alta, submetidos à esplenectomia + ligadura da veia gástrica esquerda e escleroterapia. As variáveis estudadas foram perfil evolutivo das varizes esofágicas antes e após a operação e índice de recidiva hemorrágica. RESULTADOS: Amostra foi constituída por 30 pacientes distribuídos, quanto ao gênero, em 15 doentes para cada sexo. A idade variou de 19 a 74 anos (mediana=43 anos). Houve redução do grau, calibre e red spots em todos os pacientes (p<0,05). A erradicação das varizes com escleroterapia foi alcançada em 86,7% e exclusivamente com a operação em 15,4% dos pacientes.O tempo de seguimento médio foi de 28 meses, variando de dois a 76 meses. Foram realizadas de uma a sete sessões de escleroterapia e média de três por paciente para erradicar as varizes. Quatro pacientes (13,3%) não completaram o seguimento. A recidiva hemorrágica foi de 16,7%. CONCLUSÃO: Houve redução do grau, calibre e dos red spots das varizes esofágicas em todos os pacientes.


BACKGROUND: The schistosomiasis affects 200 million people in 70 countries worldwide. It is estimated that 10% of those infected will develop hepatosplenic status and of these, 30% will progress to portal hypertension and esophagogastric varices, whose expression is through gastrointestinal bleeding with significant mortality in the first bleeding episode. Multiple surgical techniques have been developed to prevent re-bleeding. AIM: To evaluate the evolutional profile of esophageal varices after splenectomy + ligation of the left gastric vein associated with endoscopic sclerotherapy in schistosomal portal hypertension. METHODS: Prospective and observational study including schistosomiasis patients with previous history of upper digestive hemorrhage and underwent to splenectomy + ligation of the left gastric vein and sclerotherapy. The variables were: evolutional profile of esophageal varices before and after surgery and re-bleeding rate. RESULTS: The sample included 30 patients, 15 patients for each gender. The age ranged from 19 to 74 years (median = 43 years). There was a reduction in the degree, caliber and red spots in all patients (p< 0.05). The eradication of varices with sclerotherapy was achieved in 86.7% and with surgery alone in 15.4%. The mean follow-up was 28 months, ranging from two to 76 months. Were carried from one to seven sessions of sclerotherapy and the average was three per patient to eradicate varices. Four (13.3%) did not complete the follow-up. The re-bleeding rate was 16.7%. CONCLUSION: There was a reduction of the degree, caliber and red spots of esophageal varices in all patients.

ABSTRACT

OBJETIVO: Avaliar se o tratamento das malformações vasculares venosas congênitas realizado com o emprego da tecnologia laser oferece clareamento ou desaparecimento das lesões com elevado grau de satisfação informado pelos pacientes e observado pelo médico. MÉTODOS: O estudo retrospectivo reuniu 26 pacientes, portadores de malformação vascular venosa, dos quais 73,07 por cento eram do sexo feminino e que foram tratados com o aparelho PhotoDerm®. O tratamento das malformações vasculares necessitou uma média de 6,43 sessões, com intervalos de seis a oito semanas. Os pacientes incluídos neste estudo apresentavam pele tipo II (57,40 por cento) e tipo III (42,30 por cento), conforme classificação de Fitzpatric. A idade média variou de 14 a 61 anos, com média de 36,70 anos. Os dados foram obtidos através do preenchimento de protocolo informado pelo paciente. RESULTADOS: Foi informado elevado grau de satisfação (96,16 por cento) e apenas um caso (3,84 por cento) parcialmente satisfeito, considerando o clareamento ou desaparecimento das lesões. Houve desaparecimento das lesões avaliado pelo profissional médico em 80,76 por cento dos casos e em 19,24 por cento apenas clareamento. CONCLUSÃO: O tratamento das malformações vasculares venosas com o Photo-Derm® é seguro e eficiente tendo proporcionado elevado grau de satisfação dos pacientes assim como bons resultados em relação ao desaparecimento das lesões.


OBJECTIVE: To evaluate whether treatment of venous congenital vascular malformations with the use of laser technology provides lightening or disappearance of lesions with a high degree of satisfaction reported by patients and observed by the physician. METHODS: A retrospective study gathered 26 patients suffering from vascular malformation, of which 73.07 percent were female and were treated with the PhotoDerm® device. The treatment of vascular malformations needed an average of 6.43 sessions, with intervals of six to eight weeks. Patients included in this study had skin type II (57.40 percent) and type III (42.30 percent), according to the Fitzpatric's classification. The mean age ranged from 14 to 61 years, averaging 36.70 years. Data were obtained through the completion of an informed protocol by the patient. RESULTS: High satisfaction rates were reported (96.16 percent) and only one case (3.84 percent) was partially satisfied when considering lightening or disappearance of lesions. When evaluated by medical professionals, lesions disappeared in 80.76 percent and became lighter in 19.24 percent. CONCLUSION: The treatment of venous vascular malformations with Photo-Derm® is safe and effective as it offered a high degree of patient satisfaction and good results in the disappearance of the lesions.

ABSTRACT

La cirugía venosa del pene para tratamiento de la disfunción eréctil (D.E.) se hizo muy popular en la década de los '80, pero los pobres resultados a largo plazo hicieron que fuera dejada de lado; resultados mejorados asociados a criterios estrictos de selección han permitido un renovado interés por esta alternativa terapéutica de la D.E. Presentamos nuestra experiencia con la técnica de pericavernoplastía con cinta de Dacron descrita por Rossi: tres de los nueve pacientes operados presentaban erecciones útiles al control a los doce meses (33 por ciento); probablemente este bajo resultado fue más relacionada con la selección de los pacientes que con falla en la técnica quirúrgica. Creemos que puede ser una alternativa válida para servicios de salud sin acceso a prótesis de pene.


Penile venous surgery was very popular in the ’80 ies, but unsatisfactory long-term results reduced this indication for the therapy of erectile dysfunction. Better selection criteria have been associated to an increased success rate and renewed interest in venous surgery. We made an experience with the Rossi’s pericavernoplasty technique: only 33% of the patients in our group reported a good erection in the longterm follow up at 12 months. This low rate is probably more related to a poor selection of the patients than a failure of the surgical technique. We consider this could be a good option for health services with no access for penile prosthesis.

ABSTRACT

PURPOSE: To measure the levels of NO production by monocytes in patients with the hepatosplenic form of schistosomiasis mansoni who underwent splenectomy, ligature of the left gastric vein and auto implantation of spleen tissue in the major omentum. METHODS: Four groups of volunteers were enrolled in the investigation: G1 - 12 patients with S. mansoni infection in its hepatosplenic form without any kind of treatment (SMH); G2 - 13 SMH patients who underwent medical treatment and portal hypertension decompression splenectomy and ligature of the left gastric vein (SMH/SLGV); G3 - 19 patients similar to the later group, but additionally received auto implantation of spleen morsels in the major omentum (SMH/SLGV/AI); and G4 - 15 individuals with no S. mansoni infection coming from the same geographical area and presenting similar socio economical status (CG). Nitrite production by monocytes was determined by a standard Griess reaction adapted to microplates. The results were presented by mean ± SD for each group. Significant differences in NO production by monocytes were determined by Tukey-Kramer multicomparisons test. Probability values of 0.05 were considered significant. RESULTS: Patients from G1 (SMH) showed lower level of NO production by monocytes (5.28 ± 1.28µmol/ml). Patients from G2 (SMH/SLGV) showed similar results (6.67 ± 0.44µmol/ml - q = 2.681 p > 0.05). Individuals of G4 (CG) showed higher level of NO production by monocytes (8.19 ± 2.74µmol/ml). Patients from G3 (SMH/SGLV/AI) showed similar NO production by PBMC as compared to individuals of G4 (CG) - (7.41 ± 1.65µmol/ml - q = 1.615 p > 0.05). The volunteers from G4 (CG) and G3 (SMH/SLGV/AI) showed significantly greater levels of NO production by monocytes as compared to those from G1 (SMH) - (q = 5.837 p < 0.01, and q = 4.285 p < 0.05). CONCLUSION: Collectively, the results point to a restoration of NO normal production by monocytes in SH...


OBJETIVO: Mensurar os níveis de produção de ON por monócitos do sangue periférico (MSP) em portadores de esquistossomose na forma hepatoesplênica que tinham se submetido a esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico no omento maior. MÉTODOS: Quatro grupos de voluntários foram envolvidos na investigação: G1 - 12 portadores de esquistossomose hepatoesplênica sem nenhuma forma de tratamento (EHE); G2 - 13 portadores de EHE que receberam tratamento clínico e se submeteram cirurgia para descompressão do sistema porta esplenectomia e ligadura da veia gástrica esquerda (EHE/ELGE); G3 - 19 pacientes similares ao do último grupo, mas que receberam também auto-implante de fragmentos de tecido esplênico no omento maior (EHE/ELGE/AI); e G4 - 15 indivíduos sem infecção pelo S. mansoni advindos da mesma área geográfica e apresentando as mesmas condições sócio-econômicas (GC). A produção de ON pelos MSP foi determinada pela reação padrão de Griess, adaptada para poços em microplaca. Os resultados foram expressos por suas médias ± DP para cada grupo. Diferenças significantes nas medias de produção de ON pelos MSP foram determinadas pelo teste de comparações múltiplas de Tukey-Kramer. Foram aceito os limites de significância de p < 0,05. RESULTADOS: Os pacientes portadores de EHE não tratados (G1) evidenciaram os níveis mais baixos de produção de ON pelos MSP (5,28 ± 1,28µmol/ml). Os pacientes do G2 (EHE/ELGE) evidenciaram resultados similares (6,67 ± 0,44µmol/ml - q = 2,681 p > 0.05). Os indivíduos do G4 (GC) evidenciaram os mais altos níveis de produção de ON pelos MSP (8,19 ± 2,74µmol/ml). Os pacientes do G3 (EHE/ELGE/AI) evidenciaram produção de ON produzido pelos MSP similares aos indivíduos do - G4 (GC) (7.41 ± 1.65µmol/ml - q = 1.615 p > 0.05). Os voluntários do G4 (GC) e os do G3 (EHE/ELGE/AI) evidenciaram de forma significante maiores níveis de produção de ON pelos MS...

ABSTRACT

PURPOSE: Hemorrhoids are a matter of concern due to a painful outcome. We describe a simple, easy and reliable experimental model to produce hemorrhoids in monkeys. METHODS: 14 monkeys (Cebus apella) were used. After general anesthesia, hemorrhoids were induced by ligation of the inferior hemorrhoidal vein, which is very alike to humans. The vein was located through a perianal incision, dissected and ligated with a 3-0 vicryl. The skin was sutured with a 4-0 catgut thread. Animals were kept in appropriate cages and evaluated daily. RESULTS: Nine days later there were hemorrhoidal piles in the anus in fifty percent (50 percent) of the animals. Outcome was unremarkable. There was no bleeding and all animals showed no signs of pain or suffering. CONCLUSION: This is an affordable and reliable experimental model to induce hemorrhoids for experimental studies.


OBJETIVO: Hemorróidas são objeto de preocupação devido à evolução dolorosa no pós-operatório. Descrevemos aqui um modelo experimental simples e confiável de indução de hemorróidas em macacos. MÉTODOS: 14 macacos-prego (Cebus apella) foram empregados. Após anestesia geral induziu-se a formação de hemorróidas pela ligadura da veia hemorroidária inferior, que é muito parecida com a de humanos. A veia foi localizada através de uma incisão perianal, dissecada e ligada com fio de vicryl 3-0. A pele foi suturada com fio de categute 4-0. Os animais foram mantidos em jaulas apropriadas e avaliados diariamente. RESULTADOS: Nove dias após o procedimento havia mamilos hemorroidários em cinqüenta por cento (50 por cento) dos animais. Não houve intercorrências no pós-operatório. Não houve sangramento ou sinais de dor ou de sofrimento. CONCLUSÃO: Este é um modelo viável e confiável para induzir hemorróidas para estudos experimentais.

ABSTRACT

The creation of successful vascular anastomoses is of primary importance in many surgical fields. Numerous attempts to automate this process have been made. These techniques have slowly gained acceptance, but their use is still limited. This report details feasibility testing of a new prototype stapler that automates the rollover sleeve technique for venous vascular anastomoses. Male and female mongrel dogs (n=7) (25-32 kg) were used. A segment of the right (n=5) or left (n=2) iliac vein was harvested for interposition grafts after the contra lateral side was transected. In each dog, two end-to-end venous anastomoses at the interposition grafts were performed. The standard anastomosis employed continuous mattress sutures. The experimental anastomosis was performed with a new prototype surgical stapler. The stapled anastomosis was proximal and the sutured was distal. In all experiments, it was possible to perform the experimental anastomosis with the stapler. Complications included two small leaks, one due to misfiring of a single pin in one experimental site. These leaks required suture reinforcement. One dog died of hemorrhage due to a slipped suture at the vein harvest site. One vein had thrombus seen at the sutured site although no technical abnormalities at either of the anastomoses could be found. After two weeks, grafts were inspected grossly and histologically. Healing appeared normal. There was a trend for less inflammatory cells infiltrating stapled sites; however, this was not statistically significant. The experiments demonstrate that this device can automate the rollover sleeve technique for venous anastomoses.

ABSTRACT

OBJETIVO: Avaliar o efeito da esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico no omento maior, na CHP de jovens portadores de esquistossomose hepatoesplênica, que tinham se submetido a esse procedimento entre 9 e 18 anos. MÉTODOS: Quatorze pacientes com média de idade de 19,1±3,1 anos, foram incluídos no grupo pós-operatório (GI), com seguimento de 1 a 9 anos. O grupo pós-operatório (GII) consistiu de nove pacientes, média de idade de 14,0 ± 3,1 anos. Colonoscopia completa foi realizada em todos os pacientes. Pesquisaram-se lesões da CHP. RESULTADOS: Telangiectasia (GI 100 por cento vs GII 100 por cento), aumento da vascularização (GI 57,1 por cento vs GII 100 por cento), hiperemia difusa ou focal (GI 14,3 por cento vs GII 66.7 por cento), angiodisplasia (GI 7,1 por cento vs GII 33,3 por cento), e varizes retais (GI 0 por cento vs GII 55,6 por cento) foram os achados mais freqüentes. Comparando o grupo pós-operatório versus pré-operatório - c2 = 8,155 p = 0,004. CONCLUSAO: Esplenectomia e ligadura da veia gástrica esquerda tendem a reduzir as alterações vasculares da CHP em portadores de esquistossomose hepatoesplênica.

ABSTRACT

La ligadura quirurgica de las venas perforantes incompetentes de las extremidades, ha sido planteada como un método eficaz en el tratamiento de la insuficiencia Venosa crónica complicada. Este tratamiento sin embargo está asociado a complicaciones significativas de la herida. Este trabajo trata de evaluar nuestra experiencia inicial con la ligadura y división endoscópica subfacial de las venas perforantes. Desde octubre de 1995 hasta abril de 1997, son evaluadas 18 intervenciones en 14 pacientes que sufrían insuficiencia venosa crónica severa (Grado 5-6) de las extremidades inferiores, muchos de ellos (50 por ciento) habían sido operados anteriormente del mismo problema con métodos tradicionales y presentaron úlceras recurrentes. Se utilizó el equipo standard de laparoscopía de 0 grados con insuflación de CO2. En 10/18 casos fue necesario complementar con exéresis de várices superficiales. Una medida de 3 perforantes por pierna fueron satisfactoriamente cauterizadas o sexxionadas entre clips. Se demuestra que la ligadura o división endoscópica subfacial de venas perforantes es una técnica segura, que muestra resultados tempranos satisfactorios y que tiene la virtud de evitar incisiones en áreas de lipodermatoesclerosis o ulceración.

ABSTRACT

Fueron intervenidos quirúrgicamente 53 pacientes por lesiones vasculares en los últimos 6 años. Hubo 50 procedimientos en lesiones arteriales, 8 en daños venosos, 1 reimplante de miembro superior y 1 en un paciente con apertura de múltiples F.A.V. en un Sd de Klippel Trenaunay a quién se le había practicado una operación alternativa en otro país. El segmento corporal más afectado fue el miembro inferior en 27 casos en donde la arteria más dañada fue la femoral común. Las injurias venosas acompañaban generalmente a las arteriales, excepto en cuello donde fueron lesiones vasculares únicas. Las etiologías lesionales predominantes fueron el traumatismo en 17 casos y la agresión con arma de fuego en 15. El tipo de reparación quirúrgica más usada fue la exploración y la arteriorrafia. Se debieron efectuar 2 amputaciones secundarias de miembros inferiores, y una de miembro superior en un reimplante no exitoso. Las complicaciones se presentaron en el 7,6 por ciento de los casos, 1 hematoma de herida operatoria, 1 paciente con linforrea inguinal persistente y 2 infecciones en herida operatoria abdominal. La mortalidad de la serie fue del 9,2 por ciento
