ABSTRACT

A castração em fêmeas pode ser feita pela ovariectomia (retirada dos ovários), ou ovariohisterectomia (retirada dos ovários e do útero). Essa última técnica é a mais recomendada em cães e gatos, devido à prevenção de afecções que podem ocorrer posteriormente no útero. Dentre essas complicações pode-se encontrar sangramento por ligadura mal feita em coto, hidroureter, hidronefrose, piometra de coto, formação de tratos sinusais, aderência, obstrução crônica, incontinência urinária, retenção abdominal de compressas cirúrgicas, transcecção de parte do ureter e ovário remanescente. Em cadelas castradas, a causa mais comum da formação de tratos sinusais é a presença de reação tecidual ao redor do fio de sutura. O presente estudo teve como objetivo relatar um caso de uma cadela sem raça definida, 8,7 kg, seis anos, que deu entrada no Hospital Veterinário de Uberaba, MG com queixa principal a presença de ferida no flanco direito sendo tratada há nove meses, porém sem sucesso. Já haviam feito uso de vários antibióticos sistêmicos e antinflamatorios esteroidais e não esteroidais. Diante do caso observado, foram realizados exames laboratoriais e de imagem. Perante o resultado do exame de imagem, a principal suspeita foi a formação de trato sinusal com comunicação com a cavidade abdominal devido a uma reação ao fio de algodão utilizado na ovariohisterectomia.(AU)


Female animals can be castrated by ovariectomy (removal of the ovaries), or ovariohysterectomy (removal of the ovaries and uterus). The latter is the most recommended in dogs and cats due to the prevention of conditions that may subsequently occur in the uterus. Among these complications, one can find bleeding by poor ligation in the stump, hydroureter, hydronephrosis, stump pyometra, formation of sinus tracts, adherence, chronic obstruction, urinary incontinence, abdominal retention of surgical compresses, transection of part of the ureter and remaining ovary. In castrated bitches, the most common cause of the formation of sinus tracts is the presence of tissue reaction around the suture thread. This study aimed at reporting a case of a mixed breed, six-year-old dog, 8.7 kg that was admitted to the Veterinary Hospital of Uberaba with the main complaint of the presence of a wound on the right flank being unsuccessfully treated for nine months. Several systemic antibiotics and steroidal and non-steroidal anti-inflammatory drugs had already been used. In view of the observed case, laboratory and imaging exams were performed. In view of the result of the imaging examination, the main suspicion was the formation of a sinus tract with communication to the abdominal cavity due to a reaction to the cotton thread used in the ovariohysterectomy.(AU)


La castración en hembras se puede realizar mediante ovariectomía (extirpación de los ovarios) u ovario histerectomía (extirpación de los ovarios y del útero). Esa última técnica es la más recomendada en perros y gatos, debido a la prevención de afecciones que pueden presentarse posteriormente en el útero. Entre estas complicaciones se puede encontrar hemorragias por ligadura mal realizada en muñón, hidruréter, hidronefrosis, piometra de muñón, formación de tractos sinusales, adherencia, obstrucción crónica, incontinencia urinaria, retención abdominal de compresas quirúrgicas, transección de parte del uréter y ovario remanente. En las perras castradas, la causa más común de formación de trayectos sinusales es la presencia de reacción tisular alrededor del hilo de sutura. El presente estudio tuvo como objetivo reportar el caso de una perra sin raza definida, de 8,7 kg, de seis años de edad, que ingresó en el Hospital Veterinario de Uberaba, MG con el principal síntoma de presencia de una herida en el flanco derecho siendo tratada durante nueve meses, pero sin éxito. Ya habían usado varios antibióticos sistémicos y medicamentos antiinflamatorios esteroides y no esteroides. A la vista del caso observado, se realizaron exámenes de laboratorio y de imagen. A la vista del resultado del examen de imagen, la principal sospecha fue la formación de un tracto sinusal con comunicación con la cavidad abdominal debido a una reacción al hilo de algodón utilizado en el ovario histerectomía.(AU)

ABSTRACT

Antecedentes: la fístula de ano es un problema crónico para los pacientes. Causa angustia debido al mal olor y la suciedad con infecciones y secreciones recurrentes. La recurrencia y la lesión del esfínter anal fueron las complicaciones más críticas después de la cirugía. La colocación de un setón suelto y grueso fue la operación quirúrgica más prometedora. Reducir el tiempo de colocación del setón para disminuir el sufrimiento de los pacientes por la suciedad y múltiples apósitos. Pacientes y métodos: estudio retrospectivo. Cien pacientes con fístula anal alta tratados quirúrgicamente en la ciudad médica de Al-Sader y en la clínica privada diaria de Al-Najaf, ciudad de Najaf, Irak, desde febrero de 2018 hasta marzo de 2019. Se han tomado imágenes de fistulografía y resonancia magnética de todos los pacientes. Después de eso, se realiza una fistulectomía con sutura de setón suelta y gruesa durante tres meses. Los pacientes con persistencia del trayecto de trayecto fistuloso fueron sometidos a una segunda cirugía y una tercera operación hasta su completa curación. Resultados: Cien pacientes con fístula de tipo alto en ano con 96 varones (96%) y mujeres 4 (4%). La tasa de curación completa entre los pacientes masculinos después de la primera operación fue de 90 (93%), mientras que las mujeres mostraron una tasa de curación completa de 4 (100%) después de la primera operación. Tres de los pacientes varones restantes con un tracto de fístula alto persistente mostraron una curación completa después de la segunda operación, mientras que en 3 (3%) la tasa de curación completa fue del 100% después de la tercera operación. Conclusión: Un setón suelto y grueso colocado en un tracto de fístula de tipo alto durante tres meses brinda una excelente protección al esfínter anal externo con una tasa de recurrencia menor y una curación rápida.


Background: Fistula in ano is a chronic problem for the patients. It causes distressing because of foul odour and soiling with recurrent infection and discharge. Recurrence and anal sphincter injury were the most critical complications following surgery. Loose, thick seton placement was the most promising surgical operation. To reduce the time of seton placement, therefore, decreasing the suffering of patients from soiling and multiple dressing. Patients and Methods: A retrospective study. One hundred patients with high type fistula in ano treated surgically in Al-Sader Medical city and Al-Najaf daily private clinic, Najaf city, Iraq from Feb 2018 to March 2019. Fistulography and magnetic resonance imaging have taken from all patients. After that, fistulectomy with loose, thick seton suture placed for three months. Patients with the persistence of high fistula tract underwent a second surgery and third operation until complete healing. Results: One hundred patients with high type fistula in ano with male 96 (96%) and female patients were 4 (4%). The rate of complete healing among male patients after the first operation was 90 (93%), while female patients showed a 4(100%) rate of complete healing after the first operation. Three of the remaining male patients with persistently high fistula tract showed complete healing after the second operation, whereas 3 (3%) the rate of complete healing was 100% after the third operation. Conclusion: A Loose, thick seton placed in high type fistula tract for three months provides excellent protection to the external anal sphincter with less recurrence rate and rapid healing

ABSTRACT

El onfalocele o exónfalos se definen como un defecto congénito de la pared abdominal, que consiste en la herniación de las vísceras abdominales a través del anillo umbilical. Esta entidad rara vez se asocia a la comunicación del divertículo de Meckel con el saco del onfalocele. Teniendo en cuenta la escasa prevalencia de dicha entidad, compartimos el reporte de caso de un paciente recién nacido, con diagnóstico de onfalocele menor, en quien se sospechaba ruptura del saco, sin embargo, de manera intraoperatoria se encontró que la aparente ruptura del saco, correspondía a la comunicación con un divertículo de Meckel. El caso además se asoció con hallazgos ecocardiográficos de tetralogía de Fallot


Omphalocele or exomphalos are defined as a congenital defect of the abdominal wall, which consists of the herniation of the abdominal viscera through the umbilical ring. This entity is rarely associated with the communication of Meckel's diverticulum with the omphalocele sac. Considering the low prevalence of this entity, we report the case of a newborn with a diagnosis of minor omphalocele, in whom rupture of the sac was suspected; however, intraoperatively it was found that the apparent rupture of the sac corresponded to a communication with a Meckel's diverticulum. The case was also associated with echocardiographic findings of tetralogy of Fallot

ABSTRACT

Abstract Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (FGF-2) have the ability to increase vascular proliferation and permeability. The aim of this study was to quantify the release of two diffusible angiogenic growth factors (VEGF and FGF-2) after rapid maxillary expansion (RME). Thirty animals were randomly assigned to two groups. Control group (5 rats - intact suture) and Experimental groups (25 rats with RME) which were evaluated in different periods of treatment. Five animals were euthanized in different periods of healing at 0, 1, 2, 3, 5 and 7 days after RME. RT-PCR was used to evaluate the gene expression of angiogenic growth factors released on different periods of study. Data were submitted to statistical analysis using ANOVA followed by Tukey test and significance was assumed at a=0.05. RT-PCR showed that mRNAs of VEGF and FGF-2 were expressed in intact palatal suture tissue. mRNAs of VEGF and FGF-2 was upregulated in early periods (24 h) after RME (p<0.001 and p<0.01, respectively). The molecular levels of VEGF never returned to its original baseline values, and FGF-2 expression decreased up to day 5 (p<0.001) and suddenly increased at day 7, returning to its original level. RME increased VEGF secretion, but decreased FGF-2 secretion when compared to intact tissue. The results showed that these angiogenic growth factors are released and regulated in the palatal suture tissue after RME and could make an important contribution to the knowledge of overall reparative response of the suture tissue during the bone remodeling process.


Resumo Fator de crescimento endothelial (VEGF) e fator de crescimento de fibroblasto (FGF-2) tem a capacidade de aumentar a proliferação e permeabilidade vascular. O objetivo deste estudo foi quantificar a liberação dos dois fatores de crescimento (VEGF e FGF-2) após expansão rápida da maxilla (ERM). Trinta animais foram divididos aleatoriamente em dois grupos. Grupo Controle (5 ratos - sutura intacta) e grupos Experimentais (25 ratos submetidos a ERM) que foram avaliados em períodos diferentes de tratamento. Cinco animais foram eutanaziados em diferentes períodos de avaliação aos 0, 2, 3, 5 e 7 dias após ERM. RT-PCR foi usado para avaliar a expressão gênica dos fatores de crescimento liberados nos diferentes períodos de estudo. Os dados foram submetidos à análise estatística usando ANOVA seguido do pós-teste de Tukey com nível de significância de a=0.05. RT-PCR mostrou que os RNAm de VEGF e FGF-2 estavam expressos na sutura palatina mediana intacta. Os RNAm de VEGF e FGF-2 foram estimulados nos períodos iniciais (24h) após ERM (p<0.001 e p<0.01, respectivamente). Os nívies moleculares de VEGF nunca retornaram aos valores originais, e a expressão de FGF-2 reduziu até o dia 5 (p<0.001) e de repente aumentou até o dia 7, retornando aos níveis originais. ERM aumentou a secreção de VEGF, mas diminuiu a secreção de FGF-2 quando comparado ao tecido intacto. Os resultados mostraram que estes fatores de crescimento são liberados e regulados na sutura palatina mediana após ERM e podem ser de importante contribuição para o entendimento da resposta reparadora geral do tecido da sutura durante o processo de remodelação óssea.

ABSTRACT

OBJECTIVE@#To compare and analyze the mechanical differences between single-row suture anchor fixation for repairing rotator cuff injuries and double-row suture bridges for repairing rotator cuff injuries from a biomechanical perspective.@*METHODS@#The CT scan data of healthy adult shoulder joint were imported into Mimics, Geomagics and Hypermesh to carry out reverse reconstruction of two repair models, material assignment and mesh division, and the tearing of supraspinatus muscle was designed. After treatments, the load and boundary conditions were applied to the shoulder joint in ABAQUS software. The shoulder joint was fixed with four working conditions including flexion 15 °, flexion 30 °, internal rotation 15 ° and internal rotation 30 ° after anchor fixationand repair. The stress changes of the upper rotator cuff muscle and the anchor with thread were compared under these four conditions.@*RESULTS@#Under the two flexion conditions, the stress of the supraspinatus in the double row suture bridge fixation model was 8.3% and 12% less than that in the single-row suture anchor fixation, respectively. Under the two internal rotation conditions, the stress of supraspinatus in the double row suture bridge fixation model was 47% and 48% less than that in the single row fixation repair model, respectively.@*CONCLUSION@#The "load sharing" effect between the two rows of four anchors makes the stress distribution more dispersed, increases the contact area between the supraspinatus muscle and the humerus, reduces the stress of the anchor, avoids the serious stress concentration phenomenon, and explains the advantages of the fixation method of the double row suture bridge from the biomechanical angle.

ABSTRACT

BACKGROUND@#Multiple techniques are commonly used for posterior cruciate ligament (PCL) reconstruction. However, the optimum method regarding the fixation of PCL reconstruction after PCL tears remains debatable. The purpose of this study was to compare the biomechanical properties among three different tibial fixation procedures for transtibial single-bundle PCL reconstruction.@*METHODS@#Thirty-six porcine tibias and porcine extensor tendons were randomized into three fixation study groups: the interference screw fixation (IS) group, the transtibial tubercle fixation (TTF) group, and TTF + IS group (n = 12 in each group). The structural properties of the three fixation groups were tested under cyclic loading and load-to-failure. The slippage after the cyclic loading test and the stiffness and ultimate failure load after load-to-failure testing were recorded.@*RESULTS@#After 1000 cycles of cyclic testing, no significant difference was observed in graft slippage among the three groups. For load-to-failure testing, the TTF + IS group showed a higher ultimate failure load than the TTF group and the IS group (876.34 ± 58.78 N vs. 660.92 ± 77.74 N [P < 0.001] vs. 556.49 ± 65.33 N [P < 0.001]). The stiffness in the TTF group was significantly lower than that in the IS group and the TTF + IS group (92.77 ± 20.16 N/mm in the TTF group vs. 120.27 ± 15.66 N/m in the IS group [P = 0.001] and 131.79 ± 17.95 N/mm in the TTF + IS group [P < 0.001]). No significant difference in the mean stiffness was found between the IS group and the TTF + IS group (P = 0.127).@*CONCLUSIONS@#In this biomechanical study, supplementary fixation with transtibial tubercle sutures increased the ultimate failure load during load-to-failure testing for PCL reconstruction.

ABSTRACT

Shoulder arthroscopic as a conventional method usually is applied to repair rotator cuff tears. In clinical, plenty single-row, double-row and transosseous tunnels suture technique are performed, but the ideal suture technique for rotator cuff repair is not found. Compared with single-row, double-row has better strength in biomechanics property. As the two best suture technique among the single-row, massive cuff stitch and modified Mason-Allen suture have the strongest biomechanics property. Clinical trials indicate that double-row could improve healing rates, but there are no significant difference in clinical outcome functional scores. Transosseous tunnel techniques possess a better bio-mechanic property, which could improve regional micro-environment and induce tendon-bone healing. Transosseous tunnel techniques are better for small to media size rotator cuff tears and osteoporosis patient. The author suggest that optimal rotator cuff repair technique should performed according to skill of performer and individual of patient by analysing bio-mechanic properties, clinical outcome, operative complexity and patient situation. The technique should follow simple opertaion, rapid, less trauma, stable fixation and utility to perform.

ABSTRACT

OBJECTIVES: In the present study, a novel single knot tenorrhaphy was developed by combining the modified Kessler flexor tendon suture (MK) with the loop lock technique. METHODS: A total of 48 porcine flexor digitorum profundus tendons were collected and randomly divided into six groups. The tendons were transversely cut and then repaired using six different techniques, the MK method, double knot Kessler-loop lock flexor tendon suture (DK), and single knot Kessler-loop lock flexor tendon suture (SK), each in combination with the epitendinous suture (P), and the same three techniques without P. Furthermore, by performing the load-to-failure tests, the biomechanical properties and the time taken to complete a repair, for each tenorrhaphy, were assessed. RESULTS: Compared to the MK+P method, DK+P was more improved, thereby enhancing the ultimate tensile strength. The SK+P method, which required fewer knots than DK+P, was easier to perform. Moreover, the SK+P repair increased the force at a 2-mm gap formation, while requiring lesser knots than DK+P. CONCLUSION: As opposed to the traditional MK+P method, the SK+P method was improved and exhibited better biomechanical properties, which may facilitate early mobilization after the repair.

ABSTRACT

Objective: Wisdom teeth were the most common teeth affected among the rest of the teeth, these teeth need accurate evaluation and diagnosis, surgical removal of impacted wisdom needs time for incision, bone removal and suture, so the use of any instrument helps to reduce this time is essential. The objectives of this study were to estimate the time needed for the suture of oral flaps post-surgical removal of the lower wisdom teeth by using Negus knot pusher and compare it with the time used for stitching in conventional manual holding single stitching. Material and Methods: Data had been collected from thirty patients through history, clinical examination and radiographic assessment, followed by classical surgical removal performed on the same principles for all patients, at the suture level patients divided arbitrarily into two groups, control group 15 patients and 15 patients Negus pusher group, using Negus knot pusher, which is usually used to hold the stitch and stop bleeding post tonsillectomy operations by ligation, time elapsed for suturing with knot tying is calculated for both groups. Results: Among the 30 patients incorporated in the clinical study, control group mean was (1 minutes and 11 seconds and 70 milliseconds) while for the pusher group was (1 minutes and 32 seconds and 57 milliseconds), the comparison by means of T-test was not significant with the (0.424) value. Conclusion: the Negus pusher instrument can be used for the knotting stiches post wisdom teeth removal as an auxiliary tool and the time can be shortened by the use of a modified handling technique and more satisfaction for patients.

Objetivo: Os terceiros molares são os dentes mais afetados entre o resto dos dentes e necessitam de avaliação e diagnóstico precisos. A exodontia desses elementos impactados requer tempo para incisão, remoção óssea e sutura, portanto, é essencial o uso de instrumentos que ajudem a reduzir o tempo de procedimento. Os objetivos do presente estudo foram estimar o tempo necessário para a sutura de retalhos orais após a exodontia de terceiros molares inferiores utilizando o instrumental Empurrador de nó Negus (Negus Knot pusher) e compará-lo com o tempo necessário para a realização de sutura única convencional. Material e Métodos: Os dados foram coletados de 30 pacientes através da história, exame clínico e avaliação radiográfica, seguidos pela remoção cirúrgica clássica realizada através do mesmo princípio para todos os pacientes. Considerando o nível da sutura, os pacientes foram divididos arbitrariamente em dois grupos, grupo controle (n=15) e grupo Empurrador de nó Negus (n=15), o qual é geralmente utilizado para segurar o ponto e estancar o sangramento após cirurgia de tonsilectomia por ligadura. O tempo decorrido para sutura foi calculado para ambos os grupos. Resultados: Entre os 30 pacientes incluídos no estudo, a média do grupo controle foi de 1 minuto e 11 segundos e 70 milissegundos, enquanto para o grupo Empurrador de nó Negus foi de 1 minuto e 32 segundos e 57 milissegundos. A comparação intergrupo por meio do teste T não foi estatisticamente significativa (p=0,424). Conclusão: O instrumental Empurrador de nó Negus pode ser usado para sutura após a extração de terceiros molares como ferramenta auxiliar e o tempo pode ser reduzido pelo uso de uma técnica de manuseio modificada. Ademais, pode estar associado a maior satisfação dos pacientes. (AU)

ABSTRACT

Resumo Objetivo: Desenvolver um modelo treinamento utilizando tomates para aquisição de habilidades microcirúrgicas oftalmológicas. Métodos: Duas espécies de tomates (Tomate longa vida e cereja) foram utilizados, sendo utilizados tomates verdolengos e maduros. Delimitou-se com marcador permanente um círculo de raio de 0,5cm. Sob magnificação de um sistema de vídeo, foi realizado a separação da casca, tentando evitar lesionar a fruta. Após a dissecção, foi realizado a rafia da região removida com fio de mononáilon 10-0. Resultados: Os modelos utilizados mostraram-se viáveis para a realização do treinamento de dissecção microcirúrgica independente da espécie. O custo médio de cada simulador foi de menos de R$2,00. O tempo médio de dissecção foi de 10,40 ±1,84 minutos no tomate maduro e 15,20 ±2,25 minutos no verdolengos. Apenas nos tomates verdolengos foi possível realizar a rafia. Conclusão: O modelo de treinamento desenvolvido mostrou-se adequado para o treinamento inicial de várias habilidades oftalmológicas. Além disso, apresenta um baixo custo e fácil aquisição e confecção.


Abstract Objectives: Develop a training model using tomatoes to acquire ophthalmic microsurgical skills. Methods: Two species of immature and mature tomatoes (long life and cherry tomato) were used. A 0.5cm radius circle was delimited with a permanent marker. Under a magnification by a video system, the peel was separated, trying to avoid damaging the fruit. After dissection, it was performed the raffia of the peel with 10-0 mononylon thread. Results: The models used proved to be viable for training in microsurgical dissection, regardless of the species. The average cost of each simulator was less than U$ 1.00. The average dissection time was 10.40 ± 1.84 minutes for ripe tomatoes and 15.20 ± 2.25 minutes for greens. Only in immature tomatoes was it possible to make the raffia. Conclusion: The training model developed proved to be suitable for the initial training of many ophthalmic skills. In addition, it has a low cost and is easy to purchase and manufacture.

ABSTRACT

ABSTRACT Introduction: Transverse preputial island flap urethroplasty (TPIFU) is one of the most frequently performed technique for single-stage repair in proximal hypospadias. It was reported that the subepithelial urethroplasty would obviously decrease urethrocutaneous fistula (UF) complication after proximal TIP. But in the process of TPIFU, it had not been reported yet. Objective: We reviewed our experience to evaluate and compare the effect of continuous eversion suture (CES) versus continuous inversion subepithelial suture (CIS) on complication rates in the TPIFU. Material and methods: A retrospective review of all patients operated with CES and CIS in our institution between January 2017 and Jun 2017 was performed. Results: A total of 161 patients were enrolled in the research. Patients were followed up for 12~17 months. Total success rate was 73.9% (119/161). No statistically difference was found between the two groups with regard to age of patients (P=0.097), catheter size (P=0.52), time of catheterization (P=0.47), length of neourethra (P=0.20), non-urethral comorbidity (P=0.44) and post-operative infection (P=1.0). The overall postoperative complications had no statistically difference between the two groups (P=0.067). There were no statistically significant differences in the incidence of urethra-cutaneous fistula (UF) (OR=0.07, 95% CI: -0.24~0.037, P=0.22), urethral diverticulum (UD) (OR=0.026, 95% CI: -0.16~-0.056, P=0.323), urethral stricture (US) (OR=0.081, 95% CI: -0.15~0.15, P=1.0) and breakdown of urethral repair (BU) (OR=0.02, 95% CI: -0.118~-0.044, P=1.0). Discussion: The comparison of two group's postoperative complications was feasible because there were no statistically differences among perioperative variables. It seemed as if continuous inversion subepithelial suture would promote healing. However, it indicated that the overall success rate and the incidences of UF, UD, US and BU complications had no statistically difference between groups. It might be accounted for the subtle differences of techniques changing the process of establishing prime and side branches vascularization. Conclusions: The CIS technique had no significantly different effect on the four complications rates when compared with CES in TPIFU. Thus, CES and CIS could be randomly adopted in TPIFU as personal preference.

ABSTRACT

SUMMARY: Severe muscle injuries are common in accidents and have a delayed recovery of muscle integrity. In these cases, muscle suture surgery is the standard treatment. However, Platelet Rich Plasma (PRP), has been widely used in orthopedic injuries due to its growth factors. Thus, the objective of the study will be to analyze the association of suture and PRP techniques in the collagen and tenacity of the injured muscle. Were used seventy rats, divided into five groups: control (C), injury control (CI), injury and suture (IS), injury and PRP (IP), injury, suture, and PRP (ISP). Were sectioned approximately 50 % of the width and 100 % of the thickness of the gastrocnemius muscle. The homologous PRP was applied 24h after the injury. On the 7th day after the injury, the animals were euthanized and their muscles subjected to mechanical testing to measure tenacity or collagen analysis to calculate the ratio between type I and III collagen. The results show a significant decrease (p <0.05) in the values of the relationship between collagens in all injured groups (CI, IS, IP, ISP) compared to group C. In injured groups, the tenacity was significantly (p <0.05) reduced compared to the control group, with no observed difference between treatments and injured groups. The amount of collagen in the injured area has increased, but it did not affect the tenacity of the muscles, which was reduced.


RESUMEN: Las lesiones musculares graves son comunes durante los accidentes y la integridad del músculo está sujeta a una larga recuperación. En esos casos la cirugía, para la sutura del músculo, es el tratamiento común, no obstante el plasma rico en plaquetas (PRP) ha sido utilizado recientemente en lesiones ortopédicas, debido a sus factores del crecimiento. El objetivo del estudio fue analizar la asociación de las técnicas de sutura y PRP en la histología y tenacidad de músculo lesionado. Fueron utilizadas 70 ratas distribuidas en cinco grupos: control (C), control lesión (CL), lesión y sutura (LS), lesión y PRP (LPRP), lesión, sutura y PRP (LSPRP). Aproximadamente en la lesión, el 50 % de la longitud y el 100 % del espesor del músculo gastrocnemio fueron seccionados. El PRP homólogo fue aplicado 24 horas después de la lesión. En el 7º día después de la lesión los animales fueron eutanasiados y las muestras fueran sometidas al ensayo mecánico para la medición de la tenacidad y análisis del colágeno, para realizar el cálculo de la relación entre los colágenos I y III. Los resultados demostraron una reducción significativa (p<0,05) en los valores de la relación entre los colágenos en todos los grupos lesionados en relación al grupo C. La tenacidad fue (p<0,05) reducida significativamente en los grupos lesionados en relación al grupo control, sin diferencia entre los tratados. En la lesión muscular hubo disminución de los valores de colágeno, aunque en los tratamientos se observó elevación de la cantidad de colágeno en la área lesionada, esta no tuvo efecto en la tenacidad de los músculos que fue disminuida en la lesión.

ABSTRACT

Introducción. Múltiples técnicas han sido descriptas para la reconstitutición de la función del pulgar quemado, aunque sin relación costo-beneficio. El colgajo en cometa, descripto por Foucher en 1979, aporta cobertura cutánea, sensibilidad y permite mejoría funcional. El objetivo de este trabajo es presentar nuestra experiencia y resultados utilizando el kite flap. Materiales y métodos. Se realiza un estudio restrospectivo, descriptivo, de 4 casos de secuelas de quemaduras en pulgar de la mano atendidas en el Servicio de Cirugía Plástica y Reparadora del Hospital de Quemados de la Ciudad de Buenos Aires en un periodo comprendido desde el año 2016 al 2019. Se realizan colgajos en cometa en isla o tunelizados y posterior rehabilitación kinésica. El seguimiento mínimo de la serie es de 3 meses y se toman registros fotográficos pre-, intra- y posoperatorios. Las variables analizadas incluyen: sufrimiento de colgajos, dehiscencia, congestión venosa, prendimiento de injertos en zona dadora, reintervenciones y mejoría en la función de abducción del pulgar y pinza de la mano. Resultados. Se realizaron 3 colgajos en cometa tunelizados y 1 en isla. La totalidad se presentaron vitales aunque con congestión venosa en las primeras 72 hs. No se registraron complicaciones y no fueron necesarias reintervenciones. La mejoría en la función de pinza y de abducción del pulgar fue objetivable mediante la observación y referida por los pacientes y/o familiares según correspondiera. Conclusiones. Creemos que el colgajo en cometa es la mejor opción de tratamiento para las secuelas de quemadura en pulgar por aportar adecuada cobertura cutánea, ser técnicamente sencillo y poder hallar el pedículo en el 100% de la población. La congestión venosa es la regla, aunque también la supervivencia, siendo la morbilidad de la zona dadora mínima y la mejoría en la función de pinza y abducción del pulgar francamente objetivable.


Introduction. Multiple techniques have been described for repair the burned thumb function, although without cost-benefit ratio. The kite flap described by Foucher in 1979, provides skin coverage, sensitivity and allows functional improvement. The goal of this study it to present our experience and results obtained using the kite flap Materials and methods. A retrospective, descriptive study of 4 cases of burned hand's thumb treated in the Plastic Surgery Unit of the Hospital de Quemados on Buenos Aires in a three year's period from 2016 to 2019. Island or tunneled's kite flaps and subsequent kinesic rehabilitation are performed. The minimum follow-up of the series is 3 months and fotographic records pre, intra and postoperative are taken. The variables analyzed include: suffering from flaps, dehiscence, venous congestion, grafting losts on the donor zone, reinterventions and improvement in the function of thumb abduction and hand clamp . Results. 3 tunelled kite flaps and 1 on island were made. All of them were vital, although with venous congestion in the first 72 hours. No complications were recorded and no reinterventions were necessary. The improvement in hand clamp function and thumb abduction was marked through observation and when it posible, referred by patients. Conclusions. We believe that kite flap is the best option of treatment for sequelae of burns affecting hand's thumb for providing adequate skin coverage, being technically simple and being able to find the pedicle at 100% of the population. Venous congestion is the rule, although survival is also. Donor zone´s morbidity is minimal and the improvement in thumb function is clear

ABSTRACT

Objetivou-se, com este estudo, avaliar o processo de cicatrização da musculatura reto-abdominal em coelhos submetidos à laparorrafia, utilizando-se o fio de sutura à base de quitosana, comparando-o aos fios de categute cromado e poliglactina 910. Foram utilizados 24 coelhos adultos, divididos aleatoriamente em quatro grupos: quitosana e categute 15 dias (QC-15dias), quitosana e categute 30 dias (QC-30 dias), quitosana e poliglactina 910 15 dias (QP-15 dias) e quitosana e poliglactina 910 30 dias (QP-30 dias). Cada grupo foi composto por seis coelhos, nos quais foram realizadas duas incisões, uma do lado direito e outra do lado esquerdo e, posteriormente, a laparorrafia, com o fio de quitosana de um lado e o categute cromado ou poliglactina 910 do outro. Realizou-se análise clínico-cirúrgica, histológica e avaliação de achados de necropsia, além de testes de citotoxicidade e de mecânica no fio de quitosana. Ele apresentou baixa resistência mecânica e citotóxica. O fio de quitosana não proporcionou uma cicatrização satisfatória em coelhos, pois desencadeou uma resposta inflamatória acentuada.(AU)


The objective of this study was to evaluate the healing process of the recto-abdominal muscles in rabbits submitted to laparorrhaphy using chitosan-based suture yarn, comparing it to chrome catgut and polyglactin 910 yarns. Twenty-four adult rabbits were divided in to four random groups: chitosan and polyglactin 910 15 days (QP-15 days) and chitosan and polyglactin 910 30 days (QC-30 days), chitosan and polyglactin 910 15 days (QP-15 days) QP-30 days). Each group consisted of six rabbits, in which two incisions were made, one on the right side and one on the left side, and later the laparorraphy with the chitosan yarn on one side and chromed catgut or polyglactin 910 on the other. Clinical-surgical, histological and necropsy findings were evaluated, as well as cytotoxicity and mechanical tests on the chitosan wire. It presented low mechanical and cytotoxic resistance. Chitosan thread did not provide satisfactory healing in rabbits, as it triggered a marked inflammatory response.(AU)
