ABSTRACT

Resumen Objetivo La dehiscencia anastomótica (DA) en cirugía colorrectal es una de las complicaciones más devastadoras. El empleo de la angiografía de fluorescencia con verde de indocianina, se ha introducido en este campo como una herramienta prometedora para reducir la incidencia de DA. El objetivo de este estudio es valorar en nuestro medio, los resultados de la introducción de esta técnica en cuanto a prevención de DA. Materiales y Método: Se llevó a cabo un estudio prospectivo, incluyendo 59 pacientes sometidos a cirugía colorrectal resectiva a los que se les realizó una evaluación mediante angiografía con verde de indocianina intraoperatoria de la vascularización anastomótica. Resultados: Tras la aplicación de la técnica, se modificó el punto de sección en 9 pacientes (15,25%); en los cuales no se registró ninguna DA. La tasa de complicaciones global fue de 35,59% (n = 21) objetivando 3 dehiscencias anastomóticas en la serie. Conclusión: Esta técnica se perfila como una estrategia adicional en la prevención de la aparición de DA. Serán necesarios estudios randomizados con inclusión de mayor número de pacientes para obtener resultados concluyentes.


Aim: Anastomotic leakage (AL) following colorectal surgery is one of the most devastating complication. The use of indocyanine green fluorescence angiography has been developed as a promising tool to reduce the incidence of AL. The aim of this study is to evaluate the impact of this technique on the prevention of AL. Materials and Method: A prospective study was carried out, including 59 patients undergoing resective colorectal surgery. It was performed intraoperatively indocyanine green angiography evaluation of the anastomotic perfusión in all of then. Results: The section point was modified in 9 patients (15.25%); in which no AL was registered. The overall complication rate was 35.59% (n = 21), founding 3 anastomotic dehiscences in the serie. Conclusion: In conclusion, in our experience this technique is an additional strategy in the prevention of the AL. Randomized control trial including more patients will be necessary to obtain conclusive results.

ABSTRACT

Abstract Objective: To describe a new technique of sternal closure, modified from the conventional figure-of-eight approach, which can provide a secure closure and prevent sternal complications. Methods: The modified technique is based on the intercalation of the caudal portion of each steel wire passed along the sternum. This is a retrospective analysis of patients operated with this modified technique at our institution between January 2014 and December 2016. Results: One hundred and forty-three patients underwent sternal closure with the modified technique. In-hospital mortality rate was 1.4% (n=2). No sternal instability was observed at 30 days postoperatively. Two patients developed mediastinitis that required extraction of the wires. Conclusion: Short-term results have shown that the modified sternal closure technique can be used safely and effectively, with complications rates being consistent with worldwide experience.

ABSTRACT

Abstract Purpose: To compare the use of new cyanoacrylate surgical adhesive associated with macroporous tapes in cutaneous synthesis. Methods: Male Wistar rats with a longitudinal incision of 4cm were used on the back, divided into four groups: GI used octyl-cyanoacrylate (Dermabond®), GII used N-2-butylcyanoacrylate, GIII used octyl-cyanoacrylate and macroporous tape and GIV used N-2-butyl cyanoacrylate and macroporous tape. On the fourteenth day, the rats were submitted to euthanasia, were divided in two parts, and a layer of skin subcutaneous tissue through an area of operative healing was removed. One part was submitted to the study of rupture strength with the use of tensiometer, and in the other part histological examination was performed. Results: No force test was similar between groups I and II, being different from groups III and IV (P <0.001), which were identical to each other (P> 0.05). The units were compared among the studied groups, and they were different with the use of macroporous tapes (P> 0.05). Conclusions: The purpose of macroporous tapes is associated with CA adhesives in cutaneous tissues that provide more resistant scars. The use of a combination of macroporous tapes leads to complete re-epithelialization, without provoking foreign body reaction, has hemostatic properties and does not cause an absorptive reaction.

ABSTRACT

Abstract Purpose To evaluate the effect of fibrin glue on staple-line leak after sleeve gastrectomy. Methods Fourteen adult wistar rats 300 gr were randomized into two groups: Control group (n=7) and study group (n=7). All the rats underwent sleeve gastrectomy using lineer stapler. In the study group, fibrin glue was used to reinforce the staple-line. The rats were sacrificed 7 days after surgery. The stomach was resected, submerged in saline and exposed to excess pressure to obtain a burst pressure value. The gastric staple line was evaluated histopathologically according to the Ehrlich Hunt scale. The results of the two groups were compared. Results The mean Ehrlich-Hunt scores for inflammation, fibroblastic activity and neo-angiogenesis were similar between the groups (p>0.05). Collagen deposition was significantly higher in study group (3.42±0.53) when compared with control group (2.57±0.78) (p=0.035). The mean burst pressure was 137.8±8.5 mmHg for control group and 135.0±8.1 mmHg for study group (p=0.536). Conclusion Reinforcement of the staple-line with fibrin glue has no effect on the burst pressure after sleeve gastrectomy. More studies are needed to evaluate the precautions against leak after sleeve gastrectomy.

ABSTRACT

Introdução: Existem vários estudos sobre a utilização do pequi (Caryocar brasiliense) no processo cicatricial; contudo, em poucos trabalhos desenvolvidos, avaliou-se resistência dos tecidos à tensão pós-tratamento. Objetivo: Analisar a tensão cicatricial em incisões cutâneas de ratos, após terapia com Caryocar brasiliense. Método: Vinte ratos Wistar, divididos em dois grupos (placebo/tratado), sofreram incisão cutânea no dorso. O grupo tratado recebeu doses diárias de óleo de Caryocar brasiliense, e o placebo aplicação de óleo mineral. Após sacrifício, em sete e quatorze dias pós-cirurgia, amostras de pele foram submetidas à análise tênsil-histológica. Resultados: Observou-se diferença significante intergrupos na força máxima de tração, assim como uma elevação da síntese de colágeno na área das lesões no grupo tratado com óleo Caryocar brasiliense. Conclusão: A terapia com óleo de Caryocar brasiliense aumenta a resistência tênsil da pele, melhorando a resposta reparacional, reduzindo riscos de deiscência e complicações pós-cirúrgicas.


Introduction: There are several studies on the use of Caryocar brasiliense in the scarring process; however, few studies have evaluated posttreatment skin tissue resistance to tension. Objective: To analyze the scar tension in skin incisions of rats after therapy Caryocar brasiliense. Method: Twenty Wistar rats were divided into two groups (placebo / rough) and suffered skin incision in dorso. The treatment group received daily dose of Caryocar brasiliense oil and the placebo group with application of mineral oil. After sacrifice, in seven fourteen days after surgery, skin samples were subjected to tensile-histological analysis. Results: There was a significant intergroup difference in the maximum strength of traction, as well as an increase in collagen synthesis in the area of lesions in the treated group. Conclusion: Treatment with oil from Caryocar brasiliense increases the tensile strength of the skin, improving the healing response and reducing the risks of dehiscence and postoperative complications.

ABSTRACT

OBJETIVO: Analisar os casos de rotura uterina e deiscência de cicatriz uterina ocorridos em uma maternidade de baixo risco e apontar possibilidades de aprimoramento na abordagem dessas complicações. MÉTODOS: Foi realizado um estudo descritivo em uma maternidade de baixo risco com 30 leitos, que presta assistência às usuárias do sistema público de saúde. A investigação foi realizada por meio de busca dos casos em livros de registros de sala de parto e posterior leitura dos prontuários para coleta dos dados. As informações foram inseridas em formulário previamente elaborado para este estudo. Foram incluídos os casos de rotura uterina e deiscência de cicatriz uterina diagnosticados no período de 1998 a 2012, avaliados incidência, aspectos relacionados aos fatores de risco e diagnóstico, associação com o uso de misoprostol e ocitocina e desfechos observados. RESULTADOS: No período mencionado foram registrados 39.206 partos nessa instituição. A cesárea foi a conduta adotada em 10 mil partos, o que equivale a uma taxa de 25,5%. Foram identificados 12 casos de rotura uterina e 16 de deiscência de cicatriz uterina. Os resultados mais relevantes foram a alta mortalidade perinatal associada à rotura uterina e o insucesso no diagnóstico da complicação. Não foi possível demonstrar associações com o uso de misoprostol ou ocitocina. CONCLUSÃO: Os desfechos adversos da rotura uterina podem ser minimizados se esforços forem direcionados para melhorar o desempenho diagnóstico das equipes assistentes. .


PURPOSE: To evaluate the cases of uterine rupture and dehiscence of the uterine scar at a low-risk maternity and to point out possibilities for an improved approach to these complications. METHODS: A descriptive study was conducted at a 30-bed low-risk maternity hospital that provides care to users of the public health system. The investigation was carried out by searching for cases in the delivery room registry book and later reading the medical records in order to obtain the data. The information was inserted on a form previously elaborated for this study. Cases of uterine rupure and dehiscence of the uterine scar diagnosed from 1998 to 2012 were included, with the determination of incidence, aspects related to risk factors and diagnosis, association with the use of misoprostol and oxytocin, and the outcomes observed. RESULTS: A total of 39,206 deliveries were performed in this maternity during the study period, with 12 cases of uterine rupture and 16 cases of dehiscence of uterine scar being observed. The most relevant results were a high perinatal mortality associated with uterine rupture and the unsuccessful diagnosis of this complications. It was not possible to demonstrate an association with the use of misoprostol or oxytocin. CONCLUSION: The adverse outcomes of uterine rupture could be minimized if efforts were directed at improving the diagnostic performance of the assisting teams. .

ABSTRACT

Apesar dos avanços tecnológicos, pacientes submetidos ao ato anestésico-cirúrgico ainda têm complicações nas feridas operatórias. Essas feridas são classificadas como agudas e realizadas de modo a reduzir os riscos de complicações. Têm tendência à regressão espontânea e completa em um prazo esperado. No entanto, podem se tornar complexas e crônicas quando apresentam complicações no processo de cicatrização. Neste estudo tem-se como objetivos caracterizar os pacientes com ferida cirúrgica abdominal e pélvica tratados no setor de Estomaterapia de um serviço ambulatorial de um hospital em Belo Horizonte e comparar os fatores identificados nos pacientes com os citados na literatura como predisponentes às complicações na ferida cirúrgica. Trata-se de um estudo retrospectivo-descritivo, realizado no ambulatório com amostra de 22 pacientes portadores de ferida cirúrgica abdominal ou pélvica complexa. Houve predomínio de mulheres, idade variando de 22 a 79 anos, com sobrepeso ou obesidade. Todos os pacientes apresentaram deiscência na ferida cirúrgica com infecção associada em 63,6%, mais da metade das lesões apresentou área superior a 20 cm2 e a profundidade variou de 0,1 cm a 6,8 cm. A maioria recebeu alta com a ferida curada, em média, após três meses e dez dias de tratamento. Como descrito na literatura, os resultados obtidos confirmaram que o sobrepeso e a obesidade são fatores que contribuem para o desenvolvimento de infecção. Destaque-se, também, que a infecção e a deiscência foram os principais fatores que caracterizaram a ferida cirúrgica complexa.


Despite technological advances, patients submitted to surgical anesthesia procedures still suffer from surgical wound complications. These wounds are classified as acute and are made so as to reduce the risk of complications. They tend to retreat spontaneously and completely within an estimated time. However, they can become complex and chronic when there are complications in the healing process. The objectives of this study were to characterize patients with an abdominal and pelvic surgical wound treated in the Stomal Therapy Division in an ambulatory care department of a Belo Horizonte hospital and to compare the factors identified in patients predisposed to complications in the surgical wound with those reported in the medical literature. This is a retrospective, descriptive study taken at the ambulatory care with a sample of 22 patients presenting a complex abdominal or pelvic surgical wound. These were mainly women between 22and 79 years old, overweight or obese. The patients had surgical wound dehiscence associated with infection in 63.6%. More than a half of the lesions displayed an area greater than 20 cm2 and the wound depth ranged from 0.1 cm to 6.8cm. Most patients were discharged with the wound healed in about 3 months and 10 days of treatment. The results confirmed what is described in the medical literature, that is, overweight and obesity contribute to the developmentof infection. Infection and dehiscence were identified as the complex surgical wound main complication.


Aún a pesar de los avances tecnológicos pacientes sometidos a procedimientos anestésico-quirúrgicos suelen enfrentar complicaciones de heridas operatorias. Tales heridas están clasificadas como agudas y se realizan de modo a disminuirel riesgo de complicaciones. Tienen la tendencia a la regresión espontánea y completa dentro de un período esperado. Sin embargo, pueden transformarse en complejas y crónicas cuando hay complicaciones en el proceso de cicatrización. El objetivo del presente estudio fue de caracterizar a los pacientes con herida quirúrgica abdominal y pélvica tratados en el sector Estomaterapia de un servicio ambulatorial y comparar los factores identificados en los pacientes con aquéllos citados en la literatura como con predisposición a complicaciones de herida quirúrgica. Se trata de un estudio retrospectivo descriptivo realizado en ambulatorio con una muestra de 22 pacientes con heridas quirúrgico abdominal o pélvica complejas. Hubo predominio principalmente en mujeres con edades entre 22 y 79 años, con sobrepeso u obesidad. Todos los pacientes presentaron dehiscencia de herida quirúrgica asociada a infección en el 63,6%, más dela mitad de las lesiones mostró una superficie superior a los 20 cm2 con profundidad entre 0,1 cm y 6,8 cm. La mayoría fue dada de alta con la herida curada, en promedio, después de 3 meses y 10 días de tratamiento. Como descritos en la literatura, los resultados confirmaron que el sobrepeso y la obesidad son factores que contribuyen al desarrollo de la infección. También se observa que la infección y la dehiscencia son los principales factores que caracterizan la herida quirúrgica compleja.

ABSTRACT

PURPOSE: To evaluate the effects of metoclopramide on abdominal wall healing in rats in the presence of sepsis. METHODS: 40 rats divided into two groups of twenty animals, subdivided into two subgroups of 10 animals each: group (E) - treated with metoclopramide, and saline-treated control group. The two groups were divided into subgroups of 10 to be killed on the 3rd day (n = 10) or day 7 (n = 10) after surgery. Sepsis was induced by cecal ligation and puncture. We performed also the section and anastomosis in left colon. The synthesis of the abdominal wall was made with 3-0 silk thread. We measured the breaking strength of the abdominal wall and made the histopathological evaluation. RESULTS: on 3rd day postoperative, the average breaking strength in the E group was 0.83 ± 0.66 and in group C was 0.35 ± 0.46 (p = 0.010). On the seventh day, the breaking strength in group E was11.44 ± 5.07, in group C 11.66 ± 7.38 (p = 1.000). The E7 group showed lower inflammatory infiltration, foreign body reaction, fibrin than control. CONCLUSION: animals treated with metoclopramide had a higher resistance of the abdominal wall on the 3rd postoperative day.


OBJETIVO: Avaliar os efeitos da metoclopramide na cicatrização da parede abdominal de ratos na vigência de sepse. METHODS: 40 ratos divididos em dois grupos de 20 animais, subdivididos em dois subgrupos de 10 animais cada: grupo (E) - tratado com metoclopramida, e o grupo controle tratado com solução fisiologica. Os dois grupos foram divididos em subgrupos de de 10 para serem mortos no dia 3 (n = 10) ou o dia 7 (n = 10) após a cirurgia. A sepse foi induzida por ligadura e perfuração cecal. Foi realizada também a secção e anastomose em cólon esquerdo. A síntese da parede abdominal foi feita com fio de seda 3-0. Mediu-se a força de ruptura da parede abdominal e foi feita uma avaliação histopatológica. RESULTADOS: No dia 3 pós-operatório, a força média de ruptura no grupo E foi de 0,83 ± 0,66 e no grupo C foi de 0,35 ± 0,46 (p = 0,010). No sétimo dia, a força de ruptura no grupo E foi 11.44 ± 5,07; no grupo C, 11,66 ± 7,38 (p = 1,000). O grupo E7 apresentou menor infiltração inflamatória e reação de corpo estranho do que o controle de fibrina. CONCLUSÃO: Animais tratados com metoclopramida apresentaram uma maior resistência da parede abdominal no 3º dia pós-operatório.

ABSTRACT

Purpose: Urethrocutaneous fistula and neourethral dehiscence are frequently seen complications of hypospadias surgery requiring reoperation. In this study we report the experience of one surgeon with dartos flap coverage in primary hypospadias, reoperative hypospadias and urethrocutaneous fistulas repair. Methods: A total of 23 patients underwent hypospadias and urethrocutaneous fistulas repair from January 2006 to May 2009. Fourteen patients were operated on for primary hypospadias repair at our institution and 9 patients were admitted for hypospadias complications such as failed hypospadias repair and urethrocutaneous fistula. In all the patients, the dartos flap was dissected and transposed to cover the neourethra. Operative results were recorded. Results: The primary surgical procedure was a one-stage repair in 61 percent (n = 14); tubularised incised plate (TIP) urethroplasty in 43 percent (n = 6) and a Mathieu procedure in 57 percent (n = 8). Urethrocutaneous fistulas complicating the previous initial hypospadias repair were anterior in 33 percent (n = 2), middle in 33 percent (n = 2) and proximal in 33 percent (n = 2). Repair of the fistula was successful on the first attempt in all patients. The reason for redo surgery in 3 patients was complete dehiscence and the patients had distal shaft hypospadias. COconclusion: Dartos flap coverage of the neourethra seems to be an effective method of reducing the fistulous complication rate following primary and secondary hypospadias repair.


Objetivo: Fístulas uretrocutâneas e deiscências são complicações frequentes na cirurgia das hipospádias necessitando reoperações. Este estudo é baseado na experiência pessoal de um cirurgião utilizando um retalho pediculado do músculo dartos para cobertura da neouretra na correção primária de hipospádias, reoperações de hipospádias e correção de fístulas uretrocutâneas. Métodos: Vinte e três pacientes foram operados sendo 14 submetidos a cirurgia primária de hipospádia e 9 a reoperações por insucesso da correção primária ou por fístulas uretrocutâneas. Em todos os pacientes, um retalho pediculado do músculo dartos foi mobilizado e utilizado para recobrir a neouretra. Resultados: Para a cirurgia primária da hipospádia foi utilizada técnica de correção em um só tempo (n=14): uretroplastia tubularizada com incisão da placa (TIP) em 43 por cento (n=6) e técnica de Mathieu em 57 por cento (n=8). As fístulas uretrocutâneas resultantes de correções primárias anteriores eram de localização anterior em 33 por cento (n=2), média em 33 por cento (n=2) e proximal em 33 por cento (n=2). A correção das fístulas uretrocutâneas resultou em sucesso em todos os pacientes. Três pacientes necessitaram de reoperação por deiscência completa e em todos a hipospádia era distal. Conclusões: O emprego do retalho pediculado do músculo dartos para recobrir a neouretra é um método eficaz que reduz a incidência de fístulas em cirurgias primárias e nas reoperações de hipospádias.

ABSTRACT

OBJETIVO: Comparar a resistência cicatricial de anastomoses jejunais em ratos, submetidos à administração de vitamina C e de hidrocortisona, em distintos períodos pós-operatórios. MÉTODOS: Foram estudados 40 ratos Wistar, submetidos à secção e subsequente anastomose término-terminal de segmento jejunal, a 10 cm da flexura duodenojejunal. Os animais foram distribuídos em quatro grupos (n=10): Grupo I - controle; Grupo II - administração de vitamina C oral 100 mg/kg; Grupo III - administração de hidrocortisona intraperitoneal 10 mg/kg; Grupo IV - administração de vitamina C mais hidrocortisona nas doses e vias de administração acima. Avaliaram-se as pressões de ruptura anastomótica no 5º e 21º dias do pós-operatório. RESULTADOS: Os ratos que receberam vitamina C isolada ou associada a hidrocortisona tenderam a ter pressão de ruptura maior do que os demais grupos, tanto no 5º quanto no 21º dia pós-operatório. CONCLUSÃO: A vitamina C contribui para aumentar a resistência das anastomoses jejunais dos ratos durante os primeiros cinco dias do pós-operatório. A resistência das anastomoses jejunais murinas foi pouco influenciada pela administração de corticóide intraperitoneal.


OBJECTIVE: The effects of vitamin C and hidrocortisone on anastomotic healing process are controversial. The objective of the present paper was to compare the jejunal anastomotic tension in different postoperative periods. METHODS: 40 male rats weighing 200 to 400 grams were submitted to laparotomy. The jejunum was transversally cut 10 cm from the duodenojejunal flexure, and subsequently anastomosed. The rats were divided into four groups (n=10). Group I - control, Group II - oral administration of vitamin C (100 mg/kg), Group III - intraperitoneal administration of hidrocortisone (10 mg/kg), and Group IV - administration of vitamin C and hidrocortisone at the above mentioned doses. The anastomotic resistance was determined by using bursting pressure test on the 5th and 21st postoperative days. RESULTS: The resistances of the groups with vitamin C, isolated or associated to hidrocortisone trend to be higher in both postoperative periods. However, the administration of intraperitoneal steroid did not change the resistance of murine jejunal anastomosis. CONCLUSION: The results of the present study suggest that vitamin C enhances the resistance of jejunal anastomosis in the rat.

ABSTRACT

The study was conducted to compare the efficacy and safety of topical application of purified extract of human placenta (placentrex gel) versus povidone iodine for its wound healing potential after orthopaedic surgeries. In this open, comparative, randomised study, 79 patients above 18 years of age undergoing elective clean and uncontaminated orthopaedic surgery (open fracture reduction, spine surgery and debridement of wound) were enrolled in the study after obtaining written informed consent. Enrolled patients were randomised as per the PC generated randomisation chart (Rando 1.2, 2004) to receive either topical application of human placenta purified extract (PE) on the surgical wound or topical application of povidone iodine (PI) ointment on the surgical wound. Both preparations were applied topically on the surgical wound after the surgery, on days 3, 7 and on day 10, if required. Assessment of surgical wound was done after recovery from anaesthesia and on days 3, 7 and 10 based upon wound healing, physicians' global assessment of response to therapy (PGART) scale, pain and adverse effects. All 79 patients (40 PE and 39 PI) completed the study on day 10 as per the study protocol. Healing of the wound was observed in all patients. The number of patients reporting pain on days 3, 7 and 10 were similar in both PE and PI treatment (p, 0.527) groups. Wound induration was observed in 6 patients (15.00%) of PE and 15 (38.46%) of PI on day 7 (p, 0.041). None of the patients reported any side/adverse events during the study period. Purified placental extract and povidone iodine have comparative wound healing effects.

ABSTRACT

Episiotomy is a perineal incision which is the commonest surgical incision in midwifery field. This wound like others need to be cared. Nowadays, using alternative and complementary methods like essential oils which are named aromatherapy have been established as a deserving stance. Essential oils such as lavender compounded of many substances like terponents, mono terponents and linalool which are antimicrobial and pain killer. It seems this substance is very suitable for washing of wounds .So, this research carried out compare the essential oils of lavender in comparison to povidon iodine in repairing of episiotomy. This studying is randomized control trial which is carried out in 120 women. allocated in Povidon Iodine and lavender essential oil groups. At first lavender essential oil 1.5% [Stoeches acae] was prepared by Barij Essence Pharmaceutical Company in distillation method with Olive oil carrier. After child bearing to the educated women about episiotomy care, was proposed to wash wound in sitzbath by Povidon Iodine in one group and with lavender essential oil in another group. After 5th day incision was assessed. The data were analyzed by SPSS soft ware, t-test and X[2]. Data showed that the redness in 5th day reduced significantly [P<0.05]. But, rate of edema increased significantly in lavender group [P<0.001]. There is not difference between two groups for infection, pain, dehiscence. It seems that lavender essential oil is an appropriate alternative instead of Povidon Iodine, because it reduced redness and it doesn't increase infection and dehiscence

ABSTRACT

Objetivo: Comparar la fuerza tensil de heridas cerradas mediante una sutura monofilamento no reabsorbible (nylon 5-0) y un polímero adhesivo (2-octylcianoacrilato). Material y Método: Estudio experimental. En incisiones de piel, utilizando conejos de la misma raza, se han realizado dos grupos de diez conejos, con dos incisiones cada uno, cerradas con 2-octycianoacrilato y con nylon 5-0 como control. Se ha valorado la fuerza tensil mediante un tensiómetro, en 2 tiempos: al 7° día (grupo I) y al 10° día (grupo II) post cirugía, y se ha tomado una muestra para análisis histológico. Los cálculos estadísticos se hicieron a través de prueba T-Student, y un p < 0,05 se tomó como significación estadística. Resultados: El valor medio de la fuerza tensil en el grupo I fue de 9,65 + 2,72 Newtons para las incisiones cerradas con 2-octylcianoacrilato y 9,28 + 3,28 Newtons para las cerradas con nylon 5-0, no existiendo diferencia estadísticamente significativa (P = 0,801). En el grupo II el valor medio de la fuerza tensil fue 10,98 +4,80 Newtons para las incisiones cerradas con 2-octylcianoacrilato, y 9,08 + 3,58 Newtons para las cerradas con nylon 5-0, no existiendo diferencia estadísticamente significativa (p = 0,357). El estudio histológico mostró mayor inflamación, celularidad, fibrosis y proliferación vascular en incisiones cerradas con nylon 5-0. Conclusiones: La sutura de piel realizada con el polímero adhesivo 2-octylcianoacrilato es tan resistente a la tracción como la realizada con la sutura monofilamento no reabsorbible nylon 5-0 y presenta menor reacción inflamatoria local al estudio histológico.


Background: Cyanoacrylate can be used for incision closure with better esthetical results, less pain and lower incidence of infections. However, it could have a lower resistance to tension. Aim: To compare tensile strength of wounds closed with a non reabsorbable monofilament suture and octylcyanoacrylate. Material and Methods: Two skin incisions were done in the dorsal area of 20 rabbits. One incision was closed with nylon 5-0 with stitches every 0.5 cm and the other was closed with 2 layers of octylcyanoacrylate. Groups of nine rabbits were killed at seven and ten days after the procedure. A skin rectangle of the wound area was removed and the tensile force of the suture was measured with a specially devised instrument. A histological study of the incision was also done. Results: At seven days, tensile strength of sutures closed with cyanoacrylate and nylon were 9.65 + 2.72 and 9.28 + 2.38 Newtons, respectively, p=NS. At ten days, the figures were 10.98 + 4.8 and 9.08 + 3.58 Newtons respectively, p=NS. The histological study showed more inflammation, cellularity, fibrosis and vascular proliferation in sutures closed with nylon. Conclusions: No differences in tensile strength of sutures closed with cyanoacrylate or nylon were observed in this animal model. Sutures closed with nylon had a higher inflammatory reaction.

ABSTRACT

Las dehiscencias y fístulas de las anastomosis del esófago con segmentos pediculados del tubo digestivo son complicaciones frecuentes en la cirugía del esófago. En diversas estadísticas recientes, nacionales y extranjeras, se ha registrado una incidencia de hasta el 40 por ciento. Este hecho, unido a las ventajas reportadas en la utilización de los adhesivos sintéticos del tipo del tisuacril, hace interesante realizar un estudio clínico para extender el uso del producto al reforzamiento de las suturas en la anastomosis del esófago con otros segmentos del tubo digestivo, con el fin de prevenir las dehiscencias. Se realizó un ensayo clínico de fase II, prospectivo, controlado, aleatorizado, multicéntrico, a simple ciegas, que se extendió desde enero de 1998 hasta febrero de 2005. En él se incluyeron pacientes que ingresaron en los hospitales ®Calixto García¼ y ®Miguel Enríquez¼ con el diagnóstico de enfermedades esofágicas. Se logró la introducción en el país de una nueva aplicación para el adhesivo tisular tisuacril y se demostró que la utilización del producto es una opción significativamente más ventajosa que el procedimiento convencional sólo con sutura, ya que se obtuvo una eficacia del 93 por ciento en el grupo experimental respecto al 64 por ciento en el grupo control. Uno y otro grupo eran homogéneos respecto a las variables de control. El tratamiento con tisuacril disminuyó la frecuencia de aparición de fístulas esofágicas y no se reportaron eventos adversos en relación con la aplicación del producto(AU)


The dehiscencias and water-pipes of the anastomosis of the esophagus with segments pediculados of the alimentary canal are frequent complications in the surgery of the esophagus. In diverse statistical recent, national and foreign, he/she has registered an incidence of until 40 percent. This fact, together to the advantages reported in the use of the synthetic adhesives of the type of the tisuacril, makes interesting to carry out a clinical study to extend the use from the product to the reinforcement of the sutures in the anastomosis of the esophagus with other segments of the alimentary canal, with the purpose of preventing the dehiscencias. He/she was carried out a clinical rehearsal of phase II, prospective, controlled, randomized, multicéntrico, to simple blind that extended from January of 1998 until February of 2005. In him they were included patient that entered in the hospitals ®Calixto García¼ and ®Miguel Enríquez¼ with the diagnosis of illnesses esofágicas. The introduction was achieved in the country of a new application for the adhesive tisular tisuacril and it was demonstrated that the use of the product is a significantly more advantageous option that the conventional procedure only with suture, since an effectiveness of 93 percent was obtained in the experimental group regarding 64 percent in the group control. One and another group were homogeneous regarding the control variables. The treatment with tisuacril diminished the frequency of appearance of water-pipes esofágicas and adverse events were not reported in connection with the application of the product(AU)

ABSTRACT

OBJETIVO: Avaliar a associação entre o tipo dos exercícios fisioterápicos com a incidência de complicações pós-operatórias em mulheres submetidas à mastectomia radical ou quadrantectomia com linfadenectomia axilar. MÉTODOS: Ensaio clínico randomizado com 60 mulheres. O grupo direcionado fez exercícios seguindo um protocolo preestabelecido de 19 exercícios (n=30) e o grupo livre fez exercícios sem seqüência e número de repetições preestabelecidos (n=30). Realizou-se uma avaliação inicial da paciente na fase pré-operatória e reavaliações nos 14º, 28º e 42º dias pós-operatório, analisando-se como volume total de secreção drenada, tempo total de permanência do dreno, incidência de seroma e de deiscência da ferida cirúrgica e circunferência do membro superior ipsolateral. RESULTADOS: O grupo direcionado permaneceu, em média, 12,17 ± 2,96 dias com o dreno, enquanto o grupo livre 11,96 ± 2,32 dias, não havendo diferença significativa entre os grupos. A quantidade de secreção drenada durante a permanência do dreno também se mostrou semelhante entre os grupos, sendo em média de 1308,71 ± 562,6 ml no grupo direcionado e 1391,62 ± 644,65ml no grupo de exercícios livres. As incidências de seroma e de deiscência da ferida cirúrgica não se mostraram influenciadas pelo tipo de exercício em nenhum dos momentos avaliados. No grupo direcionado, 7,4 por cento e 3,4 por cento das mulheres apresentaram seroma nos 28º e 42º dias, respectivamente, enquanto 3,6 por cento e 3,6 por cento do grupo livre, respectivamente, nos mesmos momentos de avaliação. A incidência de deiscência da ferida cirúrgica também foi semelhante nos dois grupos, sendo que no grupo direcionado foi de 20 por cento no 14º dia, 31 por cento no 28º dia e 10,3 por cento no 42º dia de pós-operatório. No grupo livre a incidência foi de 23,3 por cento no 14º dia, 33,3 por cento no 28º dia e 22,2 por cento no 42º dia de pós-operatório. A circunferência do membro superior no grupo direcionado não apresentou diferença significativa em nenhum dos momentos avaliados. CONCLUSAO: As complicações não se apresentaram influenciadas pela forma de aplicação dos exercícios.

ABSTRACT

RACIONAL: Dados da literatura sugerem que, possivelmente, a lavagem intraluminar de segmentos do tubo digestivo com povidona-iodine antes da execução de uma anastomose poderia favorecer a cicatrização dessas anastomoses e prevenir a formação de aderências perianastomóticas, podendo ser útil se empregada em pacientes submetidos cirurgias do trato digestivo. OBJETIVO: Avaliar a eficácia da lavagem das bordas entéricas com povidona-iodine a 5 por cento sobre a cicatrização do cólon direito de ratos. MATERIAL E MÉTODOS: Estudaram-se 20 ratos Wistar divididos nos seguintes grupos: A (n = 10), limpeza das bordas da ferida colônica com solução salina a 0,9 por cento; B (n = 10), limpeza das bordas da ferida colônica com solução de povidona-iodine a 5 por cento. Os animais foram submetidos a laparotomia, secção de 75 por cento da circunferência do cólon, preservando 25 por cento da borda mesentérica e tratamento das bordas a serem anastomosadas segundo o grupo descrito acima. Após a realização das anastomoses, os animais foram observados durante 7 dias e, no 7º dia pós-operatório, mortos. Foram coletadas amostras de sangue para dosagem da albumina sérica e feita análise macroscópica das anastomoses, observando-se presença de fístula, aderências e dilatação acima da anastomose. O segmento contendo a anastomose colônica foi retirado com 3 cm de cólon intacto em torno da anastomose e feita medida da pressão de ruptura. RESULTADOS: Não se observou presença de fístula em nenhum animal dos grupos estudados. Não houve diferença significativa em relação à presença de estenose da anastomose, aderências ou no valor da pressão de ruptura quando comparados os dois grupos. CONCLUSÃO: O emprego da povidona-iodine não resultou em aumento da resistência tênsil das anastomoses do cólon direito de ratos.

ABSTRACT

In this study we assessed the usefulness, healing, as well as the integration to lung tissue of glutaraldehyde preserved at 0.5 bovine pericardium GPBP and lyophilized (GPBPL), after reinforced resection of lung tissue in dogs by thoracotomy or thoracoscopy. MATERIAL AND METHODS: GPBP and GPBPL were prepared and used to reinforce the suture line of lung resection in 30 mongrel dogs: Group I (n = 6): The GPBP were fixed on the lung with 4-0 polypropylene by thoracotomy. Group II (n = 6): The resection and fixed of the GPBP were performed with an linear stapler by thoracotomy. Group III (n = 6): The resection and fixed of the GPBPL were performed with an linear stapler by thoracotomy. Group IV (n = 6): The resection and fixed of the GPBP strips were performed with a linear stapler by thoracoscopy. Group V: The resection and fixed of the GPBPL strips were performed with a linear stapler by thoracoscopy. Clinico-radiological evaluation was done until euthanasia of all animals at week 8 postop. Progressive insufflation up to 40 cm H2O of airway pressure was done to evaluated resistance of the heal in the suture line reinforced. Macroscopic, and microscopic examination of the GPBP, GPBPL and lung were evaluated. RESULTS: All animals survived the surgical procedure and study time (8 weeks). No airleaks were evident at any time during the study including the insufflation test. Macroscopic examination of the GPBP and GPBPL showed good adaptation to the lung tissue. Microscopically all animals presented good healing with deposition of fibrotic tissue layer on the GPBP and GPBPL. CONCLUSION: GPBP and GPBPL are an adequate materials to reinforce lung staple line, when resection of lung tissue was performed in dogs by thoracotomy or thoracoscopy.

ABSTRACT

AIMS: To evaluate the role of subcutaneous tissue closure in relation to wound disruption after abdominal hysterectomy in obese patients. MATERIAL AND METHODS: In a prospective study at a tertiary referral centre in Mumbai, India, 60 obese patients with subcutaneous fat more than 2.5 cms were included in the study. In 30 patients, subcutaneous tissue was closed using synthetic suture (dexon) while in 30 control patients subcutaneous tissue was not closed. Average weight in the study and control groups were 69 -/+ 9.2 kg and 63.3 -/+ 11.2 kg respectively. RESULTS: The wound disruption occurred in 5 patients in non-closure group as compared to only one in the closure group. Incidence of seroma, haematoma formation and other wound complications were higher in the non-closure group. CONCLUSIONS: Closure of the subcutaneous tissue after abdominal hysterectomy of women with at least 2.5 cms of subcutaneous tissue lowers the overall rate of complications leading to disruption of the incision.

ABSTRACT

A deiscência da anastomose colorretal continua sendo um grande desafio para os cirurgiöes, pois, além da morbidade que causa, é responsável por um terço dos óbitos nas ressecçöes anteriores do reto. As causas das deiscências säo múltiplas, com destaque para as de ordem técnica, o que explica a grande variedade de incidência registrada por diferentes cirurgiöes. Independente disso, as deiscências säo mais comuns nas anastomoses baixas, no paciente idoso e quando há infecçäo local. Näo fossem esses tipos de falhas, as referidas intervençöes seriam mais seguras. A profilaxia da deiscência exige habilidade técnica especial e um senso de percepçäo capaz de antecipar o fato, virtudes inerentes ao cirurgiäo experiente e bem treinado para esse tipo de operaçäo. Sobre isso McArdle e Hole disseram: "...as conclusöes säo claras. Alguns cirurgiöes fazem aquém do ideal; uns säo menos competentes tecnicamente; outros supervisionam mal os que estäo em treinamento, sob suas responsabilidade. Esses fatores podem comprometer a sobrevida. Os resultados do nosso estudo subsidiam a opiniäo de que essas operaçöes deveriam ser feitas, exclusivamente, por cirurgiöes que desenvolvem especial interesse em cirurgia colorretal". Finalmente, o desenvolvimento dos grampeadores, circulares e retos flexíveis causou grande impacto nas intervençöes no intestino grosso, proporcionando, em situaçäo difícil, a confecçäo segura de anastomoses. As falhas mecânicas säo raras e a deiscência, geralmente, é devida ao erro do operador ou a fatores intrínsecos nem sempre perceptíveis e controláveis
