ABSTRACT

La prematiridad fue aumentando la supervivencia desde hace varios años, y eso produce, sobre todo, una preocupación en los prematuros nacidos antes de las 28 semanas de gestación. El tiempo del clampeo del cordón umbilical puede generar diversos trastornos, principalmente, cuando se realiza temprano (10-15 segundos). Ya desde hace 20 años, a través de varias investigaciones, se pudieron demostrar los notorios beneficios del clampeo demorado del cordón (de 2 a 3 minutos). Esta práctica fue instalada en la asistencia obstétrica y neonatal por las recomendaciones de sociedades científicas y de las revisiones sistemáticas, que señalaron las sólidas evidencias que apoyaban esta conducta para prematuros. En esta revisión, se describen los artículos más relevantes en los últimos años, que sustentan notoriamente la aplicación del clampeo demorado del cordón versus el clampeo temprano. Asimismo, esta práctica genera una disminución de los trastornos graves en prematuros.


For several years now, the survival of preterm infants has been increasing, which has shifted our concern to preterm infants born before 28 weeks of gestation in particular. The timing of umbilical cord clamping may lead to several disorders, especially when done early (10-15 seconds). In the last two decades, several investigations have shown the considerable benefits of delayed cord clamping (2-3 minutes). Delayed cord clamping has been practiced in obstetrics and neonatal care based on the recommendations made by scientific societies and in systematic reviews, which have provided solid evidence to support this practice in preterm infants. This review describes the most relevant articles from the last years, which strongly support the use of delayed cord clamping versus early cord clamping. In addition, this practice reduces the rate of severe disorders in preterm infants.

ABSTRACT

Hemorragia pós-parto é a maior causa de histerectomia periparto. Esta revisão descreve e ilustra as técnicas de ligaduras vasculares utilizadas no tratamento cirúrgico da hemorragia pós-parto. São apresentados os detalhes técnicos da ligadura das artérias uterinas, da ligadura das conexões útero-ovarianas, da ligadura tríplice de Tsirulnikov, das ligaduras sequenciais de AbdRabbo e de Morel e da ligadura das artérias ilíacas internas. Também são revistos os fatores que dificultam o sucesso dessas técnicas. As ligaduras vasculares são estratégias eficientes para o controle hemorrágico durante cesarianas e devem integrar o conjunto de técnicas que preservam o útero no tratamento da hemorragia pós-parto.(AU)


Postpartum hemorrhage is the major cause of peripartum hysterectomy. This review describes and illustrates the techniques of vascular ligations used in the surgical treatment of postpartum hemorrhage. The technical details of the uterine arteries ligation, of the ligation of the utero-ovarian connections, of the Tsirulnikov triple ligation, of the AbdRabbo and Morel sequential ligations and of the internal iliac arteries ligation are presented. The factors that hinder the success of these techniques also are reviewed. Vascular ligations are efficient strategies for hemorrhagic control during cesarean sections and should integrate the set of techniques that preserve the uterus in the treatment of postpartum hemorrhage.(AU)

ABSTRACT

RESUMEN El riesgo de insuficiencia hepática posoperatoria es la limitante de mayor importancia para el trata miento de pacientes con tumores hepáticos malignos primarios o secundarios. Entre las diferentes técnicas para incrementar la resecabilidad de tumores hepáticos se desarrolló una estrategia para pa cientes con tumores previamente considerados como irresecables, técnica conocida como ALPPS (as sociating liver partition with portal vein ligation for staged hepatectomy). Informamos acerca de una cirugía ALPPS en terapia reversa en un hombre referido a nuestro centro con diagnóstico sincrónico de cáncer rectal con metástasis hepáticas múltiples consideradas irresecable al momento del diagnóstico.


ABSTRACT The risk for postoperative liver failure is the most important limitation for the treatment of patients with primary or secondary liver cancer. Among the different strategies used to increase resectability in liver tumors, a technique known as ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) was developed for patients with tumors previously considered unresectable. We report the case of a male patient referred to our center with a diagnosis of synchronous multiple liver metastases of colorectal cancer considered unresectable who underwent ALPPS using liver-first reverse approach.

ABSTRACT

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.


RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

ABSTRACT

A Hemorragia Pós-parto é a maior causa mundial de histerectomia periparto. Sua abordagem terapêutica deve ser efetuada por uma sucessão de procedimentos farmacológicos e cirúrgicos antes de se recorrer à histerectomia. O acretismo placentário se apresenta como a etiologia de hemorragia pós-parto que mais dificulta a preservação uterina. Sua incidência se relaciona estritamente com a elevação contemporânea das taxas de cesárea, com os demais procedimentos cirúrgicos no útero e com a implantação segmentar da placenta. Com isso, objetiva-se relatar um caso de placenta prévia central e increta tratado por meio de excisão miometrial segmentar com reconstrução da parede uterina durante cesariana. A abordagem cirúrgica foi instituída seguindo os passos de localização per-operatória da placenta, realização de histerotomia corporal alta transversa, extração fetal, confirmação clínica do incretismo placentário, manutenção da placenta in situ, ligadura bilateral dos ramos ascendentes das artérias uterinas, ressecção de todo o segmento uterino anterior invadido por cotilédones placentários, reconstrução da parede uterina, histerorrafia, salpingotripsia bilateral, revisão da cavidade abdominal e laparorrafia. A técnica cirúrgica adotada foi eficiente na obtenção do controle hemorrágico durante a cesariana e não foi associada a complicações per ou pós-operatórias.


Postpartum Hemorrhage is the largest worldwide cause of peripartum hysterectomy. Its therapeutic approach must be performed by a succession of pharmacological and surgical procedures prior to hysterectomy. Placental accreta presents as the etiology of postpartum haemorrhage that makes uterine preservation more difficult. Its incidence is strictly related to the contemporary elevation of cesarean rates, other surgical procedures in the uterus and segmentar implantation of the placenta. We aim to report a case of central and increta placenta treated through segmental myometrial excision with reconstruction of the uterine wall during cesarean section. The surgical approach was instituted following the perioperative localization of the placenta, transverse corporal hysterotomy, fetal extraction, clinical confirmation of placental invasive aspects, maintenance of the placenta in situ, bilateral ligation of the uterine artery ascending branches, resection of the all anterior uterine segment invaded by placental cotyledons, reconstruction of the uterine wall, hysterorrhaphy, bilateral salpingotripsy, revision of the abdominal cavity and laparorrhaphy. The surgical technique adopted was efficient in obtaining hemorrhagic control during cesarean section and was not associated with per or postoperative complications.

ABSTRACT

Resumen: La ligadura de una rama de la vena porta constituye un procedimiento con buenos resultados para evitar la falla hepática posoperatoria en caso de hepatectomías extremas al provocar la hipertrofia del hígado contralateral. Sin embargo, la repermeabilización de ésta ha sido demostrada por la presencia de anastomosis porto portales intrahepáticas, pudiendo determinar una disminución de la hipertrofia esperada o necesaria. Como objetivo documentamos un caso clínico de repermeabilización intrahepática de la vena porta, evento no deseado de la hepatectomía en dos tiempos para el tratamiento de metástasis hepáticas bilobares de origen colorrectal y describimos alternativas para evitar o tratar dicha repermeabilización.


Summary: Left or right portal vein ligation to prevent post-operative liver failure in the case of extreme hepatectomy constitutes a procedure with a good prognosis, as it causes contralateral liver hypertrophy. However, its revascularization has been proved by intrahepatic porto-portal anastomoses, which could result in a reduction of the expected or required hypertrophy. The study aims to record a clinical case of intrahepatic revascularization of the portal vein, an unwanted event of the two-stage hepatectomy to treat bilobar hepatic metastasis of colorectal origin, and describe alternatives to avoid or treat such revascularization.


Resumo: A ligadura de um ramo da veia porta é um procedimento com bons resultados para evitar a insuficiência hepática pós-operatória em hepatectomias extremas por causar hipertrofia do fígado contralateral. No entanto, sua repermeabilização tem sido demonstrada pela presença de anastomose porto-portal intra-hepática, que pode determinar diminuição da hipertrofia esperada ou necessária. Como objetivo, documentamos um caso clínico de repermeabilização da veia porta intra-hepática, um evento indesejado de hepatectomia em dois estágios para o tratamento de metástases hepáticas bilobares de origem colorretal, e descrevemos alternativas para evitar ou tratar essa repermeabilização.

ABSTRACT

Introducción: Las varices esofágicas son canales vasculares que unen la circulación venosa portal y la sistémica. Se forman como consecuencia de la hipertensión portal, predominantemente en la submucosa del tercio inferior del esófago. Objetivo: Caracterizar a pacientes con rotura de varices esofágicas según principales variables clinicoepidemiológicas y terapéutico-endoscópicas. Métodos: Se realizó un estudio observacional, descriptivo y longitudinal de 20 pacientes con hemorragia digestiva alta por rotura de varices esofágicas, los cuales recibieron tratamiento endoscópico con bandas elásticas en el Servicio de Gastroenterología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de noviembre de 2016 a febrero de 2018. En el análisis estadístico se utilizó el porcentaje como medida de resumen y se aplicó la prueba de independencia de la Χ2 para identificar alguna asociación significativa entre variables. Resultados: Existió un predominio del sexo masculino (80,0 %) y del grupo etario de 51 a 60 años (40,0 %). La mayoría de los afectados presentó cirrosis hepática (60,0 %) como causa de la hipertensión portal y hematemesis (50,0 %) como forma de hemorragia digestiva alta; asimismo, el gran tamaño de las varices fue el principal factor de riesgo asociado a la rotura (70,0 %) y, luego de practicado el tratamiento endoscópico, no se produjo resangrado en la casi totalidad de los pacientes (95,0 %). Conclusiones: La aplicación de este procedimiento terapéutico resultó ser satisfactoria y no provocó complicación alguna.


Introduction: The esophageal varicose veins are vascular channels that unite the portal venous and systemic circulation. They are formed as consequence of the portal hypertension, predominantly in the submucosa of the inferior section of the esophagus. Objective: To characterize patients with break of esophageal varicose veins according to main clinical epidemiological and therapeutic-endoscopic variables. Methods: An observational, descriptive and longitudinal study of 20 patients with upper digestive bleeding due to break of esophageal varicose veins was carried out, they received endoscopic treatment with banding in the Gastroenterology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from November, 2016 to February, 2018. In the statistical analysis the percentage was used as summary measure and the chi-square test was applied to identify the existence of some significant association among variables. Results: There was a prevalence of the male sex (80.0 %) and the 51 to 60 age group (40.0 %). Most of the patients presented liver cirrhosis (60.0 %) as cause of the portal hypertension and hematemesis (50.0 %) as form of upper digestive bleeding; also, the great size of the esophageal varicose veins was the main risk factor associated with the break (70.0 %) and, after the implementation of the endoscopic treatment, there was no second bleeding in almost all the patients (95.0 %). Conclusions: The application of this therapeutic procedure was satisfactory and it didn't cause any complication.

ABSTRACT

La hemorragia diverticular es la causa más frecuente de hemorragia digestiva baja. La hemorragia es abrupta, indolora, abundante. La mayoría de los divertículos que sangran se localizan en el lado derecho, este sangrado se autolimita hasta en un 80% de los casos. Cuando no se autolimita su manejo puede llegar a ser complejo. El manejo de estos sangrados, pueden variar desde conservador, endoscópico, arteriografía más embolización y el quirúrgico. Entre las alternativas de manejo endoscópico, tenemos la terapia de inyección, la térmica, hemoclips, ligadura con banda. El presente caso es de un paciente con hemorragia diverticular en el que se realizó terapia endoscopica combinada, infiltración de adrenalina, aplicación indirecta de hemoclips y aplicación tópica de ácido tranexámico que es un antifibrinolítico.


Diverticular bleeding is the most common cause of lower GI bleeding. The bleeding is most often abrupt, painless and abundant. Most of the bleeding diverticula are located on the right side of the colon, this bleeding is self-limited in up to 80% of cases. When it is not, it could turn into a difficult situation to manage. The management of these bleeds can vary from conservative to an endoscopic, arteriography plus embolization and surgical. Among the endoscopic management alternatives, we have injection therapy, thermal therapy, hemoclips, band ligation. The present case is about a patient with diverticular bleeding who underwent combined endoscopic therapy, adrenaline infiltration, indirect application of hemoclips, and topical application of tranexamic acid, which is an antifibrinolytic.

ABSTRACT

Abstract Patent ductus arteriosus (PDA) is a clinical condition mostly found in premature newborns. Among several medical, surgical and interventional treatment options, extrapleural ligation through a left minithoracotomy is recognized as a safe, efficient and less expensive technique. In fact, it requires short surgical times, grants good exposure of the duct and nearby structures (e.g., thoracic duct, left recurrent laryngeal nerve), and avoids pleural space opening and subsequent pulmonary complications in preterm patients. This approach seems ideal due to its lower costs, especially in developing countries with a high birth rate and limited resources.

ABSTRACT

Resumen Las fístulas anorrectales complejas son un desafío para el coloproctólogo. Son una patología frecuente que afecta la calidad de vida de los pacientes. La patogénesis aún no está clara, estarían involucradas citoquinas y el proceso de transición de epitelio a mesénquima. El gold standard para su estudio es la resonancia nuclear magnética, su uso por sí mismo disminuye la recurrencia. El objetivo del tratamiento es lograr la curación sin afectar la función del esfínter evitando las recidivas. Existen múltiples técnicas, siendo la de mayor aceptación la ligadura interesfinteriana del trayecto fistuloso, con tasa de curación sobre el 70%, con mínimo impacto en continencia. Esta revisión incluye otras técnicas como el colgajo endorrectal de avance, uso de sellante, permacol, células madres, Anal fistula plug, Video asisted anal fistula treatment, Over the scope clip y fistula laser closure.


Complex anal fistula are a challenge for colorectal surgeons. It is a common pathology in population. Pathogenesis is still unclear, it would be involved citokines and the process of epitelial to eesenchymal transition. The gold standard for study is MRI, its use reduces recurrences. The goal of treatment is heal the fistula without damaging the function of the sphincter and avoid recurrences. There are multiple techniques, the most accepted is ligation of intersphincteric fistula tract with cure rate over 70%, with minimal impact in continence. This review includes other techniques like rectal advancement flap, fibrin glue, permacol, stem cells, anal fistula plug, video asisted anal fistula treatment, over the scope clip and fistula laser closure.

ABSTRACT

Abstract The aim of this study was to evaluate the effect of acute sepsis in the periodontal ligament, alveolar and furcation bone in absence of periodontitis induction through histological and immunohistochemical analyses. A septic rat model was established by cecal ligation and puncture (CLP). Twelve rats were randomly divided into CLP (n=6) and Sham (n=6) groups. The animals were euthanized at 24 h and hemimandibles were submitted to histomorfometric (bone matrix, collagenous fibers, fibroblasts, osteocytes, inflammatory cells, and blood vessels) and immunohistochemical (BMP-2/4, RANKL and osteocalcin) evaluation in alveolar bone, furcation bone and periodontal ligament. Our results demonstrated that histomorphometric parameters were similar in alveolar bone, furcation bone and periodontal ligament of Sham and CLP rats. Regarding to immunohistochemical analyses, the number of BMP-2/4 and RANKL immunolabeled cells was also similar in both groups. Furthermore, it was detected a reduction in the osteocalcin immunolabeled cells in periodontal ligaments of CLP compared to Sham rats (p=0.0014). In conclusion, the acute sepsis induction resulted in reduced number of osteocalcin labelled cells in periodontal ligament region. Moreover, no significant histological differences were observed in the periodontium of rats under acute sepsis. Considering the role of osteocalcin in bone remodeling, the study contributes to revealing the importance of careful periodontal evaluation in the presence of sepsis.


Resumo O objetivo deste estudo foi avaliar o efeito da sepse aguda no ligamento periodontal, osso alveolar e osso da furca por meio de análise histológica e imunohistoquímica. O modelo de sepse em ratos foi estabelecido pelo procedimento de ligação e perfuração do ceco (CLP). Doze ratos foram divididos de forma randomizada em ratos sépticos (n=6) e controle - grupo Sham (n=6). Os animais foram eutanasiados após 24 horas e suas hemimandíbulas foram submetidas aos procedimentos histotécnicos para análise histomorfométricos (matriz óssea, fibras colágenas, fibroblastos, osteócitos, células inflamatórias e vasos sanguíneos) e imunohistoquímicos (BMP-2/4, RANKL e osteocalcina) no osso alveolar, osso de furca e ligamento periodontal. Nossos resultados demonstraram que os parâmetros histomorfométricos foram similares no osso alveolar, osso de furca e ligamento periodontal dos animais do grupo sepse e do grupo Sham. Em relação à análise por imunohistoquímica, o número de células imunomarcadas para BMP-2/4 e RANKL também foi similar em ambos os grupos. Entretanto, houve redução (p=0.0014) no número de células imunomarcadas para osteocalcina no ligamento periodontal de ratos sépticos em relação ao grupo Sham. Como conclusão, o estabelecimento de sepse aguda resultou em um número reduzido de células imunomarcadas para osteocalcina na região do ligamento periodontal (p=0,0014). Além disso, não foram observadas diferenças histológicas significativas no periodonto de ratos na presença de sepse aguda. Considerando o papel da osteocalcina na remodelação óssea, este estudo contribui para revelar a importância da avaliação periodontal cuidadosa na presença de sepse.

ABSTRACT

@#Arteriovenous malformations (AVM) are vascular disorders with a mixture of arterial, venous and small capillary-like channels with fistulous connections. Uterine arteriovenous malformations are rare cause of abnormal uterine bleeding with only a few reported cases. They may arise from pregnancy, miscarriage, previous cesarean section or other uterine surgery and gestational trophoblastic disease. Diagnosis can be made through angiography or doppler ultrasonography. Traditionally, uterine AVMs are treated with hysterectomy but with the advances in technology, minimally invasive conservative approaches such as radiologic arterial embolization or laparoscopic uterine artery ligation have become available. We present a case of a 29-year-old, G2P1 (1011) who had a three- month history of heavy, intermittent vaginal bleeding from uterine arteriovenous malformation after a miscarriage. Laparoscopic bilateral uterine artery occlusion, offered a minimally invasive treatment with high symptomatic effectiveness.

ABSTRACT

To establish an improved animal model of sepsis induced by cecal ligation and puncture(CLP). Ninety-six male Sprague-Dawley rats were randomly divided into sham operation group(=24),intubation group(=24),CLP group(=24),and CLP+intubation group(=24).The mortality rate,abdominal cavity condition,pathological changes and pathological scores of heart,lungs,liver,and kidneys of rats in each group were observed after modeling.Blood samples were obtained from the inferior vena cava for measuring the whole blood cells(WBC)and platelets(PLT)counts and analyzing serum interleukin(IL)-6,tumor necrosis factor(TNF)-α,serum troponin T(cTnT),creatine kinase-MB(CK-MB),alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),creatinine(CREA),and blood urea nitrogen(BUN)levels.Blood gas analysis of the aorta was also performed. The mortality rates 24 h after modeling were 0 in sham operation group and intubation group,20.8% in CLP group,and 54.2% in CLP+intubation group.Pathologically,swelling and inflammatory cell infiltration in the heart,lungs,liver,and kidneys were seen in the CLP+intubation group,inflammatory cell infiltration in a single organ was seen in most rats in the CLP group,and no obvious swelling and infiltration of inflammatory cells was observed in the sham-operation group and intubation group.The myocardial histopathology score,lung tissue injury pathology score,and kidney tissue injury pathology score in both the sham-operation group and the intubation group were significantly lower than those in the CLP group and the CLP+intubation group(all =0.000).TNF-α,PaO,CK-MB,cTnT,AST,TBIL,BUN,and CREA were significantly different between sham-operation group and intubation group/CLP group/CLP+intubation group and between intubation group and CLP group/CLP+intubation group(all =0.000).The pH level was significantly different between sham operation group and intubation group/CLP group,between intubation group and CLP group/CLP+intubate group(all =0.000). Although both CLP and CLP+intubation can well mimic the pathophysiological mechanism of sepsis in rats,multiple organ dysfunction occurs in the latter.Thus,CLP+intubation can establish animal models of multiple organ dysfunction caused by sepsis induced by clinically effective abdominal infection.

ABSTRACT

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can speed up the regeneration of future liver remnant (FLR) in short period of time, and offer a chance for surgical resection for patients without sufficient FLR. However, ALPPS still remains controversy due to its high perioperative morbidity and mortality, as well as the uncertain long-term oncological benefits. How to solve these problems is the key to ensure the safety of surgery.This article focus on the indication selection, liver function reserve evaluation and timing to perform the second stage surgery, surgical mode evolution and comparison with portal venous embolization/portal venous ligation+two-stage hepatectomy.

ABSTRACT

ABSTRACT Background: Transanal haemorrhoidal dearterialization with mucopexy (THD-M) is a valuable option for treating patients with haemorrhoidal disease. However, there is still controversy with regard to its efficacy for more advanced grades. Aim: To evaluate the effectiveness of THD-M technique for treating hemorrhoidal disease and to compare the immediate and late results in different grades. Method: Seven hundred and five consecutive patients with Goligher's grade II, III or IV symptomatic haemorrhoids underwent surgical treatment using the THD-M method in five participating centres. Six well-trained and experienced surgeons operated on the patients. Average follow-up was 21 months (12-48). Results: Intraoperative complications were observed in 1.1% of cases, including four cases of haematoma, two of laceration of the mucosa, and two of bleeding. All of these were controlled by means of haemostatic suturing. In relation to postoperative complications, the most common of these were as follows: transitory tenesmus (21.4%); pain (7.2%); mucosal or haemorrhoidal prolapse (6.4%); residual skin tag (5.6%); faecal impaction (3.2%); haemorrhoidal thrombosis (2.8%); bleeding (2.1%); anal fissure (0.7%); and anal abscess (0.3%). Most of the complications were treated conservatively, and only 7.5% (53/705) required some type of surgical approach. There was no mortality or any severe complications. The recurrence of prolapse and bleeding was greater in patients with grade IV haemorrhoidal disease than in those with grade III and II (26.54% and 7.96% vs. 2.31% and 0.92% vs. 2.5% and 1.25%), respectively. Conclusion: The THD-M method is safe and effective for haemorrhoidal disease grades II and III with low rates of surgical complications. However, for grade IV hemorrhoids, it is associated with higher recurrence of prolapse and bleeding. So, THD-M method should not be considered as an effective option for the treatment of grade IV hemorrhoids.


RESUMO Racional: A desarterialização hemorroidária transanal associada à mucopexia (THD-M) tem sido indicada como alternativa à hemorroidectomia convencional para o tratamento da doença hemorroidária nos seus variados graus. No entanto, ainda hoje existe controvérsia com relação a sua eficácia para os graus mais avançados. Objetivo: Avaliar a eficácia da técnica THD-M para tratamento doença hemorroidária e comparar os resultados imediatos e tardios nos diferentes graus. Método: Entre julho de 2010 e setembro de 2015, 705 pacientes consecutivos com hemorroidas sintomáticas de graus II, III e IV foram submetidos ao tratamento cirúrgico pelo método THD-M e acompanhados por um período médio de 21 meses (12-48). As operações foram realizadas por seis cirurgiões com experiência em cirurgia colorretal, em três estados brasileiros. Resultados: Complicações intraoperatórias foram observadas em 1,1% dos casos, incluindo quatro casos de hematoma, dois de laceração da mucosa e dois de sangramento. Todos foram controlados com sutura hemostática. As complicações pós-operatórias mais comuns foram: tenesmo transitório (21,4%); dor (7,2%); prolapso mucoso ou hemorroidário (6,4%); plicoma residual (5,6%); impactação fecal (3,2%); trombose hemorroidária (2,8%); sangramento (2,1%); fissura anal (0,7%) e abscesso anal (0,3%). Não houve casos de complicações severas ou mortalidade perioperatória. A recorrência do prolapso e sangramento foi maior na doença hemorroidária grau IV do que nos graus III e II (26.54% e 7.96% vs. 2.31% e 0.92% vs. 2.5% e 1.25%; p<0,001), respectivamente. Conclusão: O método THD-M é seguro e efetivo no tratamento da doença hemorroidária nos graus II e III com baixo índice de complicações. No entanto, para a doença hemorroidária de grau IV essa técnica está relacionada com maior índice de recorrência e complicações tardias, não devendo ser considerada opção eficiente neste estágio de doença.

ABSTRACT

Introducción: Entre los tratamientos alternativos de las hemorroides se destaca por ser costo-eficientes las ligaduras elásticas convencionales. Las macroligaduras elásticas se hayan en difusión por similares resultados que las bandas elasticas convencionales. La literatura es aun escasa. El objetivo fue analizar los resultados, morbilidad y recidiva a corto y mediano plazo de hemorroides tratadas con macroligaduras. Diseño: Estudio observacional analítico prospectivo. Pacientes: 188 pacientes (110 varones y 78 mujeres). Periodo: 2011-2014. Lugar: Institución privada universitaria. Métodos: Inclusión: pacientes tratados con hemorroides internas sintomáticas. Exclusión: enfermedad anoperineal asociada, tratamiento previo, inmunocompromiso o anticoagulación. Se registraron resultados, complicaciones y recidiva. La técnica empleada fue la descripta por Reis Neto. El Seguimiento fue a 10, 30 días y 6 y 12 meses y 5 años. Resultados: Todos fueron tratados con internación de corta estadía. La edad fue 49,5 años (23-76). Los síntomas fueron prolapso 96, sangrado 44 y ambos 48. Se realizó sólo una sesión en 178 casos (94,6%). Se trataron 2 paquetes en 122 y 3 en 66. El dolor moderado fue en 5 casos y prolongado en 2. El sangrado leve y tenesmo se presentó en la mayoría de los pacientes, pero desapareció en la primera semana. Se registró sangrado inmediato moderado en 5% sin sangrado severo inmediato. Otras complicaciones inmediatas: 2 trombosis y 3 congestión/edema local. En 1 paciente ocurrió un sangrado que requirió de internación sin necesidad de cirugía en forma alejada. Sólo en 3 casos se realizó resección local de plicomas previos. En 139 casos se realizó como único procedimiento. La recidiva fue 6 casos. (2 al primer año y 4 a los 5 años), 5 se trataron con nueva macroligadura y 1 con cirugía. No se registró ninguna complicacion severa, infecciosa o única relacionada al procedimiento. El seguimiento a 1 año fue del 100% y a 5 años del 96%. Discusión y conclusiones: El tratamiento con macroligaduras para el prolapso hemorroidario presentó con baja morbilidad sin complicaciones severas. Los resultados son reproducibles entre diferentes autores. Son el tratamiento ideal para las hemorroides grado III con poco componente externo. (AU)


Introduction: Alternative therapies for internal hemorrhoid plexus are several procedures with specific indications for each grade of hemorrhoid. Due to some major advantages, rubber band ligation has become probably in the most popular between colorectal surgeons. The high-macro rubber band ligation appears to be as the first choice but literature is few. Objective: To analyze results, morbidity and recurrence of internal hemorrhoid disease treated with high-macro rubber band ligation. Design: Observational non-randomized prospective analysis. Patients: 188 patients (110 male). Period: 2011-2014. Setting: Private Institution. Methods: Patients with symptomatic internal hemorrhoid disease (grade II-III-IV). Results, Immediate and late complications and 5 years recurrence were registered. Technique used was the original description by Reis Neto. Patients with immunosuppression, additional perianal disease, previous treatment and anticoagulation were excluded. Results: There was only one session in 178 cases. Two banding were placed in 122 and 3 in 66. Symptoms were prolapse in 96, bleeding in 44 and both in 48. 139 patients were treated as only procedure. Tenesmus and light hemorrhage occurred in most cases. Moderate or late pain was registered in 7 cases, and immediate moderate bleeding in 5%. There was no severe immediate bleeding. Immediate morbidity was 2 thrombosis and 3 anal congestion. There was one moderate late bleeding at day 28 and required admission. Recurrence occurred in six cases, 5 were ligated again and 1 was treated by conventional surgery. There was none severed or unique complication or infection associated. Discussion and conclusion: Macrorubber band presented low morbidity and there are no severe complications at 5 years follow-up. Recurrence of prolapse is low and could be treated by a new session with equal morbidity. Results are equivalent and reproducible by different authors. This procedure might be the ideal treatment for hemorrhoid prolapse. (AU)

ABSTRACT

Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepatic artery, Group III- isolated selective ligation of the portal vein and Group IV- combined ligation of portal vein and hepatic artery. Before procedure and five days after a 3D CT Scan was performed to analyze the hypertrophy, weight and function of the remnant liver. Results: The largest regeneration rate and increase of weight in the hypertrophied lobe was detected in group IV, the first with an average of 3.99 (p=0.006) and the last varying from 6.10g to 9.64g (p=0.01). However, total liver weight and the R1 ratio (Hypertrophied Lobe Weight/Total Liver Weight) was higher in group III (P<0.001) when compared with groups I, II and IV and showed no difference between them. The immunohistochemical examination with PCNA also found higher percentages with statistical significance differences in rats of groups III and IV. It was possible to confirm a strong correlation between hypertrophied lobe weight and its imaging volumetric study. Liver function tests only showed a significant difference in serum gamma-glutamyltransferase and phosphorous. Conclusion: There is a largest liver regeneration after combined ligation of portal vein and hepatic artery and this evidence may improve the knowledge of surgical treatment of liver injuries, with a translational impact in anima nobile.

ABSTRACT

Resumen Los espirales de embolización (coils o microcoils) son los agentes más comúnmente usados, con un éxito técnico reportado en aproximadamente el 81-100 % de los casos. Los espirales o coils se encuentran disponibles en una amplia variedad de configuraciones y tamaños, lo que permite acomodarse a vasos de distintos calibres; además, por su buena radiopacidad, tienen la ventaja de ser liberados con precisión. Los espirales o coils son el análogo de una ligadura arterial quirúrgica, debido a que producen una oclusión mecánica por su posicionamiento en el lumen vascular, lo que disminuye el flujo sanguíneo, y sus fibras sintéticas tienen un efecto trombogénico adicional. Caso: presentamos cuatro casos del Hospital Universitario Fundación Santa Fe de pacientes con várices gástricas tratadas satisfactoriamente con embolización transcatéter con coils, los cuales tuvieron un buen resultado técnico; además presentamos una revisión de la literatura.


Abstract Coils and microcoils, the most commonly used embolization agents, have reported technical success rates ranging from 81% to 100% of cases. The spirals or coils are available in a wide variety of configurations and sizes which fit into vessels of different calibers. They have good radiopacity allowing for accurate release. Coils are the analogue of a surgical arterial ligation, because they produce mechanical occlusion due to their positioning in the vascular lumen. This decreases blood flow while their synthetic fibers have an additional thrombogenic effect. Case: We present four cases of coil embolization treatment of gastric varicose veins at our institution. All procedures were successful and had good technical results. We also present a review of the literature.

ABSTRACT

Objective: The aim of this study was to investigate loose brackets in relation to various related factors in orthodontic patients who had completed orthodontic treatment. Material and Methods: In this retrospective study, 738 medical records of patients who had undergone comprehensive orthodontic treatment and matched specific inclusion criteria were selected. Paired t-tests and ANOVA, along with the Mann-Whitney test and Kruskal­Wallis analyses were performed to compare the means of variables between selected subgroups. Results: Loose brackets were found most frequently on premolars, followed by incisors and then canines (p<0.01). Male and young patients were found to have a higher incidence of loose brackets compared to female and adult patients (p=0.044 and p<0.01, respectively). The highest correlation coefficient value was found between treatment duration and total number of loose brackets (0.393), which was statistically significant. Conclusions: The frequency of total number of loose brackets increased with younger age group. Premolar teeth were found to be the most commonly affected teeth, followed by incisors and canines. Mandibular teeth presented more loose brackets than maxillary.


Objetivo: Fue investigar brackets sueltos en relación con varios factores relacionados en pacientes ortodónticos que habían completado el tratamiento de ortodoncia. Material y Métodos: En este estudio retrospectivo, se seleccionaron 738 registros médicos de pacientes que se habían sometido a un tratamiento ortodóntico integral y criterios de inclusión específicos coincidentes. Se realizaron pruebas t pareadas y ANOVA, junto con la prueba de Mann-Whitney y los análisis de Kruskal-Wallis para comparar las medias de las variables entre los subgrupos seleccionados. Resultados: Se encontraron corchetes sueltos con mayor frecuencia en los premolares, seguidos de incisivos y luego caninos (p<0.01). Se encontró que los pacientes masculinos y jóvenes tenían una mayor incidencia de corchetes sueltos en comparación con los pacientes femeninos y adultos (p=0.044 y p<0.01, respectivamente). El valor del coeficiente de correlación más alto se encontró entre la duración del tratamiento y el número total de corchetes sueltos (0.393), que fue estadísticamente significativo. Conclusiones: La frecuencia del número total de corchetes sueltos aumentó con el grupo de edad más joven. Los dientes premolares fueron los dientes más afectados, seguidos de los incisivos y los caninos. Los dientes mandibulares presentan más brackets sueltos que los maxilares.
