ABSTRACT

INTRODUCCIÓN: La dehiscencia anastomótica (DA) es una complicación severa en cirugía colorrectal con una incidencia que oscila entre 2 y 19%. La literatura internacional muestra numerosos estudios sobre la identificación de factores de riesgo (FR), mientras que en la nacional existen solo dos series que analizan esta complicación. OBJETIVO: Realizar una caracterización descriptiva de resultados institucionales y establecer la tasa de DA, sus factores de riesgo asociados y la mortalidad. MATERIALES Y MÉTODO: Serie de casos no concurrente, cuya muestra son pacientes consecutivos intervenidos de patología colorrectal con anastomosis primaria con o sin ostoma derivativo entre los años 2004 y 2016. Se realiza modelo de regresión logística univariable y multivariable. RESULTADOS: Se obtuvieron 748 pacientes, 50,5% mujeres, media de edad fue 56,2. Las indicaciones quirúrgicas más frecuentes fueron cáncer colorrectal en 381 (50,9%) pacientes y enfermedad diverticular en 163 (21,8%). La DA fue de 5,6% (42/748) y la mortalidad fue de 2% (15/748), siendo de 1% para los electivos (7/681). En el análisis univariado encontramos que los FR que tuvieron significancia estadística fueron la albúmina (p < 0,001), altura anastomosis (p < 0,001), transfusión (p < 0,001), localización (colon derecho > izquierdo) (p = 0,011), mientras que en el análisis multivariado fueron la albúmina (p = 0,002) con un OR 3,64 (IC 95% 1,58-8,35) y transfusión (p = 0,015) con un OR 7,15 (IC 95% 1,46-34,91). CONCLUSIÓN: Nuestra serie es la más grande reportada en Chile, con resultados similares a estudios internacionales y nacionales. Establecemos que la hipoalbuminemia y la presencia de transfusiones intraoperatorias se asocian a alta tasa de DA.


INTRODUCTION: Anastomotic leakage (AL) is a severe complication in colorectal surgery, its incidence ranges from 2 to 19%. In international literature, we found numerous studies on the identification of risk factors (RF), while in the national there are only two series that analyze this complication. AIM: Perform a descriptive characterization of institutional results and establish the AL rate, its associated risk factors and mortality. MATERIALS AND METHOD: Non-concurrent series of cases, whose sample is consecutive patients operated for colorectal pathology with primary anastomosis with or without a derivative ostoma between 2004 and 2016. Univariate and multivariable logistic regression model was performed. RESULTS: There were 748 patients, 50.5% women, mean age was 56.2. The most frequent surgical indications were colorectal cancer in 381 (50.9%) patients and diverticular disease in 163 (21.8%). The AL was 5.6% (42/748) and the mortality was 2% (15/748), being 1% for the electives (7/681). In the univariate analysis, we found that the RF that had statistical significance were albumin (p < 0.001), anastomosis height (p < 0.001), transfusion (p < 0.001), location (right colon > left) (p = 0.011), while that in the multivariate analysis were albumin (p = 0.002) with an OR 3.64 (IC 95% 1.58-8.35) and transfusion (p = 0.015) with an OR 7.15 (IC 95% 1.46-34.91). CONLUSION: Our series is the largest reported in Chile, with similar results to international and national studies. We establish that hypoalbuminemia and the presence of intraoperative transfusions are associated with a high rate of AL.

ABSTRACT

Abstract Purpose: To evaluate the most frequent surgical techniques of high-risk colorectal anastomoses in rats. Methods: Wistar rats were enrolled in three different models comprising inflammatory (TNBS enema), vascular (portal vein occlusion) or obstructive (a non-ischemic constricting ring) mechanisms associated with colonic anastomosis that had accomplished after these former lesions. Histological analyses (Hematoxylin and eosin and Picrosirius red) were performed. Results: All anastomoses techniques were associated with risk factors and had complications, mainly anastomotic leakage. In Study 1, the use of a pharmacological agent, trinitrobenzene sulfonic acid (TNBS) mimicked an inflammatory bowel disease such as Crohn's disease with 50% of anastomosis leakage, the higher percentage among all models tested. In Study 2, after portal ischemia followed by reperfusion it was observed a dense neutrophil infiltrate in the midst of necrotic tissue and fibrin at the anastomotic site and 5 days after the anastomosis, no collagen was produced. In Study 3, 5 days after the mechanical obstruction some denuded areas of epithelium with marked oedema of mucosa and submucosa were seen, at the anastomotic site and anastomosis group showed some reduction of collagen density when compared with Control/Sham group. Conclusion: All the experimental surgical techniques tested in rats were associated with high-risk colorectal anastomoses and were useful to study colonic anastomotic healing and intestinal leakage.

ABSTRACT

Abstract Purpose: To investigate the possible effects of argan oil on the healing of colorectal anastomoses. Methods: I n Group 1 (sham), laparotomy was performed and the colon was mobilized. In the control (Group 2) and argan oil (Group 3) groups, colonic resection and anastomosis were applied. To the control and sham groups, 2 mL of 0.9% NaCl was administred rectally, and in the argan oil group, 2 mL/day argan oil was applied rectally for 7 days. Results: The mean bursting pressures of the argan oil and sham groups were significantly higher than the values in the control group. A significant difference was determined between the tissue hydroxyproline and prolidase levels of control group and other groups. Histopathologically, argan oil showed significant beneficial effects on colonic wound healing. In the argan oil and sham groups, the tissue malondialdehyde and fluorescent oxidation product levels were found to be lower and total sulfhydryl levels were higher than the control group. Conclusions: The rectally administered argan oil was observed to have significantly ameliorated wound healing parameters and exerted a significant antioxidant effect. This is the first study in the literature about the beneficial effects of argan oil on colorectal anastomoses.

ABSTRACT

Abstract Purpose: To compare platelet rich plasma (PRP) and fibrin glue about the effect of anastomotic healing. Methods: Thirty six Wistar-Albino male rats diveded into 3 groups according to control(Group1), PRP (Group 2) and fibrin glue(Tisseel VH) (Group 3). The colon was transected with scissor and subsequently an end to end anastomosis was performed using continuous one layer 6/0 vicryl sutures. Postoperative 7th day effect of anastomotic healing measuring with tissue hydroxyproline(TH) level and anastomotic bursting pressure(ABP); moreover comparison of cytokine (IL-6 and IL-10) and procalcitonin levels on 1st,3rd and 7th days. Results: There was no statistically significant difference of the ABP and hydroxyproline levels between PRP and fibrin glue on the 7th day. There was no statistically significant difference between levels of proinflammatory cytokine (IL-6) (P=0.41), anti-inflammatory cytokine (IL-10) (P=0.35), and procalcitonin levels (P=0.63) on 1, 3 and 7 days. Conclusion: Fibrin glue and platelet rich plasma are shown to be effective in healing intestinal anastomoses without superior to each other.

ABSTRACT

Introducción: La hemicolectomía derecha con anastomosis ileocólica es una cirugía frecuentemente realizada para la que existen muchas formas de realizarla. Objetivo: Evaluar cuál es la mejor anastomosis ilecólica en términos de morbimortalidad y realizar una evaluación comparativa de la evolución clínica posoperatoria según el tipo de configuración anastomótica. Pacientes y Método: Estudio observacional analítico, con criterios de inclusión y exclusión definidos. Las variables a estudiar las dividimos en dos grupos, las relacionadas a la técnica quirúrgica y su configuración anastomótica, y las variables relacionadas con resultados de la intervención quirúrgica, creando una tabla de contingencia en que se cruzan los datos. Análisis de datos con STATA 13.0. Resultados: 216 pacientes con anastomosis ileocólica, destacando significancia estadística al cruzar: A) reoperación y tipo de sutura (p = 0,044), con un OR 3,4 (IC 95% 0,94-18,6), siendo de mayor riesgo la mecánica; B) mortalidad y urgencia (p = 0,001) con un OR 7,76 (IC 95% 1,56-49,29), siendo de mayor riesgo la cirugía de urgencia. Las anastomosis isoperistálticas possen eliminación de gases (p < 0,001), tránsito intestinal (p = 0,009) e ingesta de sólidos (p = 0,005) más precoz. Hay expulsión de gases antes en el abordaje laparoscópico, sutura manual, configuración término lateral e isoperistáltica de la anastomosis y cirugía electiva. Conclusión: Existe gran variabilidad de técnicas para realizar la anastomosis ileocólica. La anastomosis manual muestra menor probabilidad de necesitar una reintervención quirúrgica, la cirugía electiva tiene menor mortalidad que la realizada de urgencia. Sugerimos realizarla vía laparoscópica, con sutura manual, término lateral, isoperistáltica y de forma electiva, por tener una recuperación más corta.


Introduction: Right hemicolectomy with ileocolic anastomosis is a frequent surgery with many ways to perform it. Objective: To evaluate which is the best ileocolic anastomosis in terms of morbidity and mortality and to make a comparative evaluation of the postoperative clinical evolution according to the type of anastomosis. Patients and Method: Analytical observational study, with defined inclusion and exclusion criteria. The variables to be studied are divided into two groups, those related to the surgical technique and its anastomotic configuration, and the variables related to the results of the surgical intervention, creating a contingency table that crosses the data. Data analysis with STATA 13.0. Results: 216 patients with ileocolic anastomosis, highlighting statistical significance when crossing: A) reoperation and type of suture (p = 0.044), with UN or 3.4 (95% CI 0.94 to 18.6), being of greater risk the mechanics; B) mortality and urgency (p = 0.001) with an OR 7.76 (95% CI 1.56-49.29), with emergency surgery being of greater risk. Isoperistaltic anastomosis with gas elimination (p < 0.001), intestinal transit (p = 0.009) and solid intake (p = 0.005) earlier. There is earlier expulsion of gases in the laparoscopic approach, manual suture, end-to-side and isoperistaltic of the anastomosis and elective surgery. Conclusion: There is great variability of techniques to perform the ileocolic anastomosis. Manual anastomosis is less likely to require surgical reoperation, elective surgery has a lower mortality than that of emergency surgery. We suggest performing it laparoscopically, with manual suture, lateral term, isoperistaltic and electively, for having a shorter recovery.

ABSTRACT

Introducción: La filtración anastomótica (FA) en cirugía colorrectal aumenta la morbimortalidad. La identificación de factores de riesgo y la creación de un modelo predictivo ayudaría en la decisión de crear un ostoma desfuncionalizante, hecho que, actualmente, recae en el criterio del cirujano. Dekker creó el Colon Leakage Score (CLS) estableciendo criterios objetivos. Objetivo: Establecer el CLS en pacientes intervenidos por cáncer de colon izquierdo y recto en Clínica INDISA, estableciendo valores de corte locales, su sensibilidad y especificidad. Pacientes y Método: Corresponde a un estudio de pruebas diagnósticas, cuya intervención es la aplicación del CLS comparándolo con la presencia de filtración anastomótica (gold standard), definida por criterios clínicos y radiológicos. Se utilizó análisis de curvas ROC, índice de Youden y regresión logística. Resultados: De 180 pacientes, hubo FA en 12 (6,6%). La media de CLS en quienes hubo FA fue de 11,5 y en quienes no hubo FA de 6,9 (p = 0,0001). El área bajo la curva para predicción de FA con el CLS fue de 0,829 (IC 95% 0,69-0,96), con un valor de corte de 11, sensibilidad de 67% y especificidad de 89%. En el análisis de regresión logística, el OR para la predicción de FA utilizando el CLS fue de 1,48 (IC 95% 1,22-1,79 p < 0,001). Conclusión: El CLS es una herramienta que permite predecir el riesgo de FA en pacientes intervenidos por cáncer de colon izquierdo y recto. Ante un valor mayor o igual a 11 se debería crear un ostoma protector, generando un cambio en la práctica clínica.


Introduction: Anastomotic filtration increases morbidity and mortality in colorrectal surgery. Identification of risk factors and creation of a predictive model would help the decision of creating a defunctionalizing ostoma, that currently is taken by the surgeon. Dekker created de Colon Leakege Score (CLS) with objective criteria. Objective: Establish CLS in patients that underwent left colon and rectum surgery with cancer diagnosis in Clinica INDISA, define the local cutting value, it's specificity and sensibility. Patients and Methods: Corresponds to a diagnostic test's study, that intervention is CLS application, comparing with the presence of anastomotic filtration (gold standard), defined by clinical and radiologic criteria. For the analysis, ROC curves, Youden's index and logistic regression. Results: From 180 patients, anastomotic filtration was present in 12 (6.6%). Average CLS score in patients with anastomotic filtration was 11.5 and in those without anastomotic filtration was 6.9 (p = 0.0001). Area under the curve for anastomotic filtration prediction using CLS was 0.829 (CI 95% 0.69-0.96) with a cutting value of 11, 67% of sensibility and 89% of specificity. Logistic regression analysis, OR for anastomotic filtration prediction using CLS was 1.48 (CI 95% 1.22-1.79 p < 0.001). Conclusion: CLS is a tool that permits predicting anastomotic filtration risk in patients that underwent left colon and rectum surgery. With a CLS value equal or more than 11, we should create a protective ostoma, generating a clinical practice local change.

ABSTRACT

O objetivo do presente estudo foi avaliar a hemogasometria venosa de equinos com lesões isquêmicas induzidas experimentalmente no cólon menor. Foram utilizados oito equinos sadios, com idades entre cinco e oito anos, sem raça definida. Os animais foram submetidos à celiotomia e a quatro horas de obstrução intraluminal do cólon menor. Foram realizadas coletas de amostras de sangue imediatamente antes da indução anestésica (T0), no momento em que a anestesia foi estabilizada (T1), quatro horas após a obstrução intraluminal (T4), e, durante o pós-cirúrgico, as coletas foram realizadas em intervalos de 12 horas até completar 72 horas (T16, T28, T40, T52, T64 e T76). Notou-se em T4 alcalose metabólica, com compensação respiratória por meio da hipoventilação. Esse quadro de alcalose foi brando e transitório, retornando os valores normais para a espécie em T16, com 12 horas de desobstrução intestinal.(AU)


The objective of this study was to evaluate the blood gas analysis of venous blood of horses with experimentally induced ischemic lesions on the lower colon. Eight healthy horses were used, with ages between five and eight years, mixed breed. The animals were subjected to celiotomy and four hours of lower colonic intraluminal obstruction. The harvests were made with the blood samples immediately before induction of anesthesia (T0), when the anesthesia was stabilized (T1), 4 hours after the intraluminal obstruction (T4) and during postsurgical times were performed at intervals of 12 hours to complete 72 hours (T16, T28, T40, T52, T64 and T76). The occurrence of metabolic alkalosis on T4 with respiratory compensation by hypoventilation was noted, this alkalosis period was bland and transient, returning the normal values for the specie on T16, 12 hours after the intestinal obstruction.(AU)

ABSTRACT

Abstract Purpose: To investigate if fluorescein fluorescent test can predict dehiscence in a model of ischemic colonic anastomosis in rats. Methods: This experimental controlled trial randomly assigned 55 rats to four groups. Anastomoses were performed in non-ischemic colon segments (control group) and in ischemic colon segments measuring 1, 2 or 3 cm long (groups 1, 2 and 3, respectively). Fluorescein was injected and the tissues were examined under ultraviolet light. Seven days later, a second-look surgery was performed to check for the presence or absence of anastomosis dehiscence. Results: Twenty-four rats presented anastomotic dehiscence during the second-look surgery. Reticular and nonfluorescent patterns were significantly associated with the occurrence of anastomotic dehiscence. Fluorescein fluorescence had a sensitivity of 95.8%, specificity of 89.2%, positive predictive value of 88.4%, negative predictive value of 96.2%, and accuracy of 92.3% to predict anastomotic dehiscence. Conclusion: Fluorescein fluorescent test can accurately predict leak in a model of ischemic colonic anastomosis in rats.

ABSTRACT

Background: Ulcerative colitis [UC] patients failing medical management require colectomy


Methods: Literature search in MEDLINE , CINAHL and Embase, targeting studies reporting the outcomes of colorectal procedures [from 2002 to 2016 with total and subtotal colectomy postoperative complications in adults with ulcerative colitis as an endpoint. Texts and authoritative Web sites were also reviewed then identification of papers according to the inclusion and exclusion criteria and data extraction were performed by two independent researchers


Results: Following data extraction and synthesis, we identified 24 articles for review. Reporting outcomes from procedures conducted from 2002-2016. Most frequent short-term complications: infectious complications and ileus [mean incidence 21% and 19%], while most frequent long-term complications: pouchitis, fecal incontinence and small bowel obstruction [mean incidence 31%, 22% and 18%]. Post-operative early complications [

Conclusion: Although Colectomy remains an appropriate therapeutic strategy for specific groups of patients- it is not the optimal cure for UC. Clinicians need to fully understand the various postoperative complications and comorbidities that are highly prevalent with over a third of patients expected to experience long-term or late arising post-operative complications. Thus, while surgical procedures are recommended as an appropriate therapeutic strategy for a specific group of patients, the post-operative complications associated with these surgical procedures should not be underestimated

ABSTRACT

Objetivo: Valorar en el intraoperatorio en tiempo real, el flujo sanguíneo de los cabos anastomóticos y la anastomosis. El objetivo final de este trabajo busca que este sea el inicio de un estudio prospectivo, con el fin de auditar las anastomosis colónicas de forma intraoperatoria buscando así disminuir el número de fallas de suturas. Material y método: Se realizó un estudio prospectivo, observacional y descriptivo, desarrollado en el Hospital de Clínicas en el período comprendido entre enero de 2014 y julio 2015. Se incluyeron en el mismo pacientes sometidos a resección de colon y reconstrucción primaria del tránsito intestinal de coordinación. El indocianina verde (ICG) se empleó como colorante vital fluorescente para la valoración in situ de la anastomosis colónica. La presencia de falla de sutura en el postoperatorio en relación con la perfusión anastomótica objetivada con ICG constituye un parámetro de importancia en nuestro estudio. Resultados: En lo referente a la perfusión de la anastomosis, destacamos que en el primer caso la misma fue sensiblemente inferior en el cabo colónico, en tanto que en los 2 casos restantes la vascularización de los cabos fue óptima. Conclusiones: La técnica con ICG constituye una herramienta apropiada para poder auditar la calidad de las anastomosis intestinales realizadas de coordinación. Se trata de una técnica segura, aplicable en nuestro medio. Siendo un predictor de falla de sutura, permite un descenso de la morbimortalidad postoperatoria por esta causa.


Aim: Rate intraoperatively in real time, blood flow and ends anastomotic and anastomosis. The ultimate goal of this work seeks to make this the beginning of a prospective study in order to audit the colonic anastomosis intraoperatively and seeking to reduce the number of sutures failure. Material and method: A prospective, observational and descriptive study, to be held in the Clinics Hospital in the period between January 2014 and July 2015. They were included in the same patients undergoing resection of colon and intestinal transit reconstruction on primary coordination. Indocyanine green (ICG) was used as a fluorescent vital dye for in situ evaluation of colonic anastomosis. The presence of failure postoperative suture relative to the anastomotic objectified perfusion with ICG, is an important parameter in our study.Results:Regarding the perfusion of the anastomosis, in the first case it was significantly lower than in the colonic out. While in the remaining two cases the vascularization of the ends was optimal. Conclusions: The technique with indocyanine green is an appropriate tool to audit the quality of intestinal anastomoses performed coordination.

ABSTRACT

INTRODUÇÃO: Há um grande empenho na busca por soluções reconstrutivas para as áreas de perda cutânea ou muscular que exijam cobertura ou preenchimento cavitário estável. O retalho anterolateral da coxa, descrito na China por Song et al. (1984), é considerado por muitos como o retalho ideal nas grandes reconstruções. OBJETIVO: Relatar a aplicabilidade do retalho anterolateral da coxa como recurso versátil nas reconstruções da parede abdominal. MÉTODOS: Dois pacientes foram selecionados para serem submetidos à ressecção tumoral de cólon direito com invasão da parede abdominal pela equipe de cirurgia oncológica em conjunto com a equipe de cirurgia plástica, que foi a responsável pela reconstrução da parede abdominal. Em ambos os casos, utilizou-se o retalho anterolateral da coxa pediculado, que foi transposto para o defeito após a ressecção parcial da parede abdominal no mesmo tempo cirúrgico. Entre as vísceras abdominais e o retalho, foi fixada tela de PROCEEDTM para reforço da parede abdominal. Resultados: Ambos os pacientes tiveram boa evolução pós-operatória e encontram-se em acompanhamento, sem sinais de recidiva tumoral e com boa qualidade de vida. CONCLUSÃO: O retalho anterolateral da coxa mostrou-se recurso útil dentro do arsenal terapêutico reconstrutivo da parede abdominal devido a grandes ressecções tumorais em oncologia.


INTRODUCTION: There is a strong commitment in pursuing reconstructive solutions for areas of skin or muscular loss that require covering or stable cavity filling. The anterolateral thigh flap, described in China by Song et al. (1984), is considered by many as the optimal flap in large reconstructions. OBJECTIVE: To report the applicability of the anterolateral thigh flap, as a versatile resource in reconstructions of the abdominal wall. METHODS: Two patients were submitted to tumoral resection of the right colon with invasion of the abdominal wall by a team of oncologic surgeons in conjunction with the plastic surgery team that was responsible for the reconstruction of the abdominal wall. In both cases, the pedicled anterolateral thigh flap was used, which was transposed to the defect after partial resection of the abdominal wall at the same surgical time. A PROCEEDTM surgical mesh was fixed between the abdominal viscera and the flap to reinforce the abdominal wall. RESULTS: Both patients had good postoperative evolution and are in follow-up, with no signs of tumor recurrence and with a good quality of life. CONCLUSION: The anterolateral thigh flap is a useful resource for the reconstruction of the abdominal wall due to large tumor resections in oncology.

ABSTRACT

PURPOSE: To investigate the effects of medical ozone theraphy on the colon anastomosis of peritonitis model in rats. METHODS: Eighteen rats were randomly assigned into three equal groups; control, cecal punctuation and colon anastomosis and ozone theraphy. Sepsis was performed with a cecal punctuation in groups 2 and 3. The medical ozone theraphy was administered intraperitonealy for three weeks in group 3 while the other rats received saline injection. At the twenty second day serum were obtained for TNF-α and IL-1β, the colonic burst pressures were measured and colonic tissue samples were obtained for MDA and MPO levels. Histolopatological examination was evaluated with H&E stain, and Ki-67, IL-1β and the VEGF immunostaining densities were also compared. RESULTS: Intraperitoneal ozone administration reversed TNF-α, IL-1β, MDA and MPO levels and the colonic burst pressures. There was also a significant difference at immunostaining densities of histopathological examination. CONCLUSION: Medical ozone therapy may contribute to tissue healing by affecting the proliferation and the vascularization thus has benefits on colonic anastomosis at peritonitis in rats.

ABSTRACT

Abstract OBJECTIVE To identify the occurrence of surgical site infection (SSI) and its risk factors in patients undergoing colon surgery in a tertiary hospital located in the countryside of the state of São Paulo. METHOD Retrospective cohort study, with collection of information contained in the medical records of patients undergoing colon surgery in the period between January 2010 and December 2013. The studied variables were the possible risk factors related to the patient, to demographic characteristics and the surgical procedure. RESULTS In total, were evaluated 155 patients with an overall SSI incidence of 16.7%. A statistically significant association was found both in the univariate as in the multivariate analysis between the SSI and the following variables: male gender, Charlson index and mechanical bowel preparation. CONCLUSION The understanding of health professionals about the factors that influence the incidence of SSI in colon surgery may contribute to the quality of care provided to surgical patients, from effective actions to minimize the risk of infections.

ABSTRACT

Background : The use of long-chain polyunsaturated fatty acids has been studied in the context of healing and tissue regeneration mainly due to its anti-inflammatory, immunoregulatory and antioncogenic properties. Previous studies have demonstrated beneficial effects with the use of enteral immunonutrition containing various farmaconutrients such as L-arginine, omega-3, trace elements, but the individual action of each component in the healing of colonic anastomosis remains unclear. Aim : To evaluate the influence of preoperative supplementation with omega-3 fatty acids on the healing of colonic anastomoses of well-nourished rats. Methods : Forty Wistar adult male rats, weighing 234.4±22.3 g were used. The animals were divided into two groups: the control group received for seven days olive oil rich in omega-9 oil through an orogastric tube, while the study group received isocaloric and isovolumetric omega-3 emulsion at a dose of 100 mg/kg/day, also for seven days. Both groups were submitted to two colotomies followed by anastomosis, in the right and left colon, respectively. Parameters evaluated included changes in body weight, anastomotic complications and mortality, as well as maximum tensile strength by using a tensiometer and collagen densitometry at the anastomotic site. Results : There were no differences in body weight or mortality and morbidity between groups. The value of the maximum tensile strength of the control group was 1.9±0.3 N and the study group 1.7±0.2, p=0.357. There was, however, a larger amount of type I collagen deposition in the study group (p=0.0126). The collagen maturation índex was 1.74±0.71 in the control group and 1.67±0.5 in the study group; p=0,719). Conclusions : Preoperative supplementation of omega-3 fatty acid in rats is associated with increased collagen deposition of type I fibers in colonic anastomoses on the 5th postoperative day. No differences were observed in the tensile strength or collagen maturation index.


Racional : O uso de ácidos graxos poliinsaturados de cadeia longa tem sido estudado no contexto de cicatrização e regeneração do tecido, principalmente devido a suas propriedades imunorreguladoras, antioncogênicas e anti-inflamatórias. Estudos anteriores demonstraram efeitos benéficos com o uso de imunonutrição enteral contendo vários farmaconutrientes (L-arginina, ômega-3, oligoelementos), mas a ação individual de cada componente na cicatrização de anastomose colônica permanece incerto. Objetivo : Avaliar a influência da suplementação no pré-operatório com ácidos graxos ômega-3 na cicatrização de anastomoses colônicas de ratos eutróficos. Método : Quarenta ratos Wistar, machos adultos, pesando 234,4±22,3 g foram divididos em dois grupos: grupo controle recebeu a suplementação de azeite de oliva (rico em ômega-9) por gavagem por sete dias e o grupo estudo recebeu ômega-3 em forma de emulsão isocalórica e isovolumétrica, também por gavagem, na dose de 100 mg/kg/dia por sete dias no pré-operatório. Ambos os grupos foram submetidos à duas colotomias seguidas de anastomose colônica, em cólon direito e cólon esquerdo, respectivamente. Foram avaliados a evolução do peso dos animais, morbimortalidade e realizados testes tensiométrico e de densitometria do colágeno dos corpos de prova. Resultados : Não houve diferenças na evolução do peso e na morbimortalidade entre os grupos. O valor da força de tração máxima do grupo controle foi de 1,9±0,3N e no grupo estudo de 1,7±0,2, p=0,357. Houve, no entanto, maior quantidade de colágeno tipo I (p=0,0126) na anastomose no grupo estudo. O índice de maturação do colágeno foi cálculado para os grupos (1,74±0,71 - grupo controle; 1,67±0,5 - grupo estudo, p=0,719). Conclusões : A suplementação pré-operatória com ácido graxo ômega-3 está associada ao aumento da deposição de colágeno do tipo I em anastomoses de cólon em ratos no 5º dia do pós-operatório, mas não exerce influência na resistência tênsil de colorrafia ou no índice de maturação do colágeno.

ABSTRACT

PURPOSE : To evaluate the effects of metoclopramide on metalloproteinases (MMP) and interleukins (IL) gene expression in colonic anastomoses in rats. METHODS : Eighty rats were divided into two groups for euthanasia on the 3rd or 7th postoperative day (POD), then into two subgroups for sepsis induction or not, and then into subgroups to receive either metoclopramide or saline solution. Left colonic anastomosis were performed and then analyzed. RESULTS : On the 3rd POD, metoclopramide was associated with increased expression of MMP-1a, MMP-13, and TNF-α. On the 7th POD, the transcripts of all MMPs, TNF-α, IL-1β, IFN-γ, and IL-10 of the treated animals became negatively modulated. In the presence of sepsis, metoclopramide did not change MMPs and decreased IL-6, IL-1β, IFN-γ and IL-10 gene expression on the 3rd POD. On the 7th POD, increased expression of all MMPs, IFN-γ and IL-10 and negative modulated TNF-α and IL-6 gene expression. CONCLUSION : Administration of metoclopramide increased metalloproteinases and interleukins gene expression on the 3rd postoperative day and negatively modulated them on the 7th POD. In the presence of abdominal sepsis, metoclopramide did not change MMPs and decreased ILs gene expression on the 3rd POD. On the 7th POD, the drug increased expression of all MMPs.

ABSTRACT

Introducción: al comparar la poca difusión de las resecciones de colon y recto laparoscópicas con respecto a otros procederes como las coleciscistectomías, funduplicaturas, cardiomiotomías, vemos que se debe fundamentalmente a tres inconvenientes: incremento de los costos directos, complejidad técnica y dudas en cuanto a respetarse los criterios oncológicos en el caso específico del cáncer colorectal. La complejidad técnica que entraña esta cirugía determina una larga curva de aprendizaje y un elevado índice de conversión al compararlo con otros procederes. En 1995 se comenzó a realizar en el Centro Nacional de Cirugía Endoscópica las resecciones laparoscópicas de colon y recto. Objetivo: analizar los factores que se relacionan con el índice de conversión en las resecciones laparoscópicas de colon y recto. Métodos: se realizó un análisis de 660 resecciones de colon y recto llevadas a cabo en el Centro Nacional de Cirugía de mínimo acceso entre los años 1996 y 2012. Se muestran las intervenciones realizadas, tiempo quirúrgico, morbilidad, índice de conversión y las causas que lo motivaron. Resultados: el índice de conversión descendió de 16 por ciento en las primeras 50 cirugías a 4 por ciento en las ultimas 50. La morbilidad global resultó un 16 por ciento y se incrementó a un 33,3 por ciento en los casos convertidos a cirugía abierta, al igual que la mortalidad (2 por ciento / 5,4 por ciento). Conclusiones: la conversión debe ser decidida tempranamente con vistas a disminuir la morbilidad. La adecuada selección de pacientes y la experiencia del equipo quirúrgico son inversamente proporcionales al índice de conversión(AU)


Introduction: Little diffusion of the use of laparoscoipic colon and rectal resections compared to that of other surgical procedures such as cholecystectomy, funduplicature and cardiomyotomy is basically due to three disadvantages: increase of direct costs, technical complexity, and existing doubts on the oncologic criteria to be respected for in the specific case of colorectal cancer. The technical complexity of this surgery implies much training and high conversion index when comparing it with other surgical procedures. The National Center of Endoscopic Surgery began to perform laparoscopic colon and rectal surgery in 1995. Objective: To analyze the factors that relate with the conversion index in the laparoscopic colon and rectal resections. Methods:Analysis of 660 colon and rectal resections performed at the National Center of Minimal Access Surgery from 1996 through 2012. Performed operations, surgical time, morbidity, conversion index and causes were all presented in this paper. Results: The conversion index decreased from 16 percent in the first 50 surgeries to 4 percent in the last 50. Global morbidity rate was 16 percent but increased to 33.3 percent in cases converted to open surgery as it happened in mortality (2 percent to 5.4 percent). Conclusions: The decision on conversion to open surgery must be early taken with a view to decreasing morbidity rates. Adequate selection of patients and experience of the surgical team are inversely proportionate to the conversion index(AU)

ABSTRACT

PURPOSE: To evaluate the influence of glutamine and obstructive jaundice on left colon healing in rats. METHODS: Sixteen male rats were allocated across four groups: LG - Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct ligation until euthanasia. L - Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. No glutamine supplementation. M - Common bile duct manipulation followed by colotomy and bowel suture on postoperative day 7. No glutamine supplementation. MG - Common bile duct manipulation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct manipulation until euthanasia. On the day of euthanasia, bursting pressure of the sutured bowel segment was measured and samples were collected for histopathological analysis. RESULTS: There were no differences in bursting pressure among groups : LG vs. M (110 ± 28 vs. 173 ± 12; p = 0.08). Groups L and MG were not different from group M (156 ± 12 and 118 ± 22. Glutamine supplementation was associated with less edema, polymorphonuclear lymphocyte infiltration, bacterial colonies, and abscess formation, as well as with increased collagen formation. CONCLUSION: Obstructive jaundice had no negative effect and glutamine supplementation had no positive effect on colonic scar strength in rats. .

ABSTRACT

El tratamiento de las lesiones traumátcas del colon ha experimentado cambios importantes durante los últmos años, que nos han permitdo ofrecermejores opciones al manejo de éste tpo de trauma y por consiguiente un mejor “confort” para el paciente que, en el pasado, tenía que soportar losefectos indeseables de una cirugía derivatva como la colostomía, y luego someterse a una segunda intervención para su tratamiento defnitvo contodos los riesgos que esto conlleva. Aún existen controversias que están relacionadas con el tempo de evolución principalmente en cuanto al tratamientoprimario retrasado, presencia de shock, lesiones asociadas y grado de contaminación que podrían estar relacionadas con incremento en latasa de morbilidad y mortalidad. Hemos hecho una revisión crítca de la literatura relacionada con estos tópicos que nos ofrecen un mejor panoramade las mejores opciones de tratamiento utlizando una mejor evidencia y en consecuencia ofrecer recomendación adecuada debido a que aún existeincertdumbre acerca de su seguridad.


During recent years, colon injury treatment has experimented important changes that allow us to ofer beter optons for treatng this trauma andconsequently a beter “comfort” for the patents who, in the past, had to deal with the undesirable efects of a derivatve surgery like colostomy, andthen had a second interventon for their defnitve treatment with all the risks that it takes. There are stll controversies related with evoluton tme,mainly concerned the delayed primary treatment, shock presence, associated injuries and contaminaton grade, that could be related with increase ofmorbidity and mortality rates. A critcal literature review related with those topics has been done, that ofers a beter scene of the top treatment choicesusing beter evidence and consequently, ofers an appropriate recommendaton, because there is stll uncertainty about its safety.

ABSTRACT

PURPOSE: We evaluated the hypothesis that induced perioperative hypothermia (32 ± 1ºC) affects the redox balance in the tissue of colonic anastomosis in rats by modifying biochemical enzymatic and non-enzymatic markers related to oxidative stress. METHODS: Forty-eight male Wistar rats were randomly divided into eight experimental groups of six animals each and underwent laparotomy, sigmoid section and immediate anastomosis. Four groups were operated under normothermia (36 ± 1ºC), and the other four under hypothermia (32 ± 1ºC). The animals were reoperated on days 3, 7 and 14 postoperatively, and two groups underwent SHAM at 3 days. From the scar tissue samples, the activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) was evaluated, and the levels of non-enzymatic markers of oxidative stress, such as reduced glutathione (GSH) and lipid peroxidation, were measured by the thiobarbituric acid reactive substances (TBARS) assay. The means were compared between groups corresponding to each day of sampling and euthanasia. RESULTS: The hypothermic groups showed a significant reduction on the activity of SOD on day 7 postoperatively, on the activity of CAT on days 7 and 14 postoperatively and on the levels of GSH on day 7 postoperatively. The level of lipid peroxidation was increased in the hypothermia group on day 7 postoperatively and decreased on day 14 compared with the normothermic groups. CONCLUSION: Perioperative hypothermia reduced the activity of the antioxidant enzymes catalase and superoxide dismutase, glutathione levels and increased lipid peroxidation in the scar tissue of colonic anastomoses in rats. .
