ABSTRACT

Introducción: Los pacientes con cáncer de colon tienen un riesgo de obstrucción intestinal maligna (OIM). El objetivo del estudio fue determinar la prevalencia de la OIM en un grupo de pacientes con cáncer de colon en un centro de referencia regional público. Metodología: El presente estudio transversal se realizó en el Hospital General IESS Ceibos de Guayaquil -Ecuador de marzo 2017 a junio del 2020. Se incluyeron pacientes con cáncer de colon incidentes en el período de estudio. Las variables fueron edad, sexo, presencia de OIM. Se utiliza estadística descriptiva en frecuencias y porcentajes. Resultados: Se analizan 90 pacientes, 55 hombres (61.11%). La edad más prevalente fue el grupo de 61 a 70 años 27 casos (30%).La comorbilidad más prevalente fue la hipertensión arterial en el 36%. El tipo histológico predominante fue el adenocarcinoma de colon en el 94.44%. 61.11% tuvieron un tumor en el recto y 15.56% en la unión rectosigmoidea. La prevalencia de OIM fue de 55 casos 61.11% (IC95% 60.77-61.45%). En 15 casos (16.67%) fue obstrucción completa y 36 casos (40%) fue obstrucción parcial. La mortalidad fue de 52 casos (57.78%). La presencia del tumor en la unión rectosigmoidea OR=6.188 (IC95% 1.282-29.86) P=0.0232. Conclusión: La prevalencia de OIM es alta más del 61%. La presencia del tumor en la unión recto-sigmoidea fue un factor de riesgo para el desarrollo de OIM.


Introduction: Patients with colon cancer are at risk of malignant intestinal obstruction (MIO). The study aimed to determine the prevalence of MIO in a group of patients with colon cancer in a public regional reference center. Methodology: This cross-sectional study was carried out at the IESS Ceibos General Hospital in Guayaquil, Ecuador, from March 2017 to June 2020. Patients with incident colon cancer were included in the study period. The variables were age, sex, and the presence of MIO. Descriptive statistics are presented as frequencies and percentages. Results: Ninety patients were analyzed, 55 men (61.11%). The most prevalent age group was 61 to 70, with 27 cases (30%). The most prevalent comorbidity was arterial hypertension (36%). The predominant histological type was colon adenocarcinoma (94.44%). A total of 61.11% had a tumor in the rectum, and 15.56% had a tumor in the rectosigmoid junction. The prevalence of MIO was 55 cases, 61.11% (95% CI 60.77-61.45%). In 15 cases (16.67%), there was complete obstruction; in 36 cases (40%), there was partial obstruction. Mortality was 52 cases (57.78%). The presence of the tumor in the rectosigmoid junction OR=6.188 (95% CI 1.282-29.86) P=0.0232. Conclusion: The prevalence of MIO is high, at more than 61%. The presence of a tumor in the rec-tosigmoid junction was a risk factor for the development of MIO.

El estado vital por laparoscopía fue fallecido 12.5%, y abierta 28.8%, en relación a su enfermedad tumoral Conclusión: Las comorbilidades quirúrgicas y recuperación fueron menores por laparoscopía, pero la cirugía abierta mostro mejores resultados anatomopatológicos post quirúrgicos


Introduction:Laparoscopic surgery is a safe alternative for colon cancer treatment and allows all the advantages of a minimally invasive procedure. The objective of the present investigation was to measure the impact on morbidity of the open vs. closed surgical technique in colon cancer.Methodology: The study was carried out at the Solón Espinosa Ayala Hospital, in Quito-Ecuador, from March 2012 to March 2017, with a non-probabilistic sample, including elderly patients with colon cancer. Socio-demographic variables, histology, days of hospitalization, surgical bleeding, surgical time, hospital stay, surgical margins, resected lymph nodes, the start of the diet, % surgical conversion, surgical com-plication, recurrence, surgical morbidity, and surgical mortality are included. Univariate and bivariate de-scriptive statistics are used.Results: 85 cases are analyzed; 52 underwent open surgery, and 33 underwent laparoscopic surgery. The surgical conversion was 75% due to adhesions and 25% due to duodenal infiltration. The similar surgical time is 121 to 180 minutes 61%. Laparoscopic complications 2.3% and 9.4% open (pelvic col-lections and intestinal fistulas 2.4% vs 1.7%). Malnutrition was not related. Start of diet 2 to 4 days 83% laparoscopic and 67% open. Hospitalization from 4 to 8 days was laparoscopic 87% and open 78%. Blood loss less than 100cc was laparoscopic in 82% and opened in 60%. Lymph node resection (+13) in lapa-roscopy 69.6% and open 68.1%. The proximal margin of the surgical piece by laparoscopy is 5.1 to 10cm (43.5%), by open (55.3%), the tumor recurrenceof 56.2% and 52.3%. The mortality in laparoscopy surgery was 12.5%, and in open surgery was 28.8%.Conclusion: Laparoscopy's surgical comorbidities and recovery were lower, but open surgery showed better post-surgical pathological results

ABSTRACT

Introducción: La apendagitis epiploica es un proceso inflamatorio producido por daño estructural debido a torsión que genera zonas hemorrágicas o isquémicas, o bien por una inflamación circundante que afecta los apéndices y genera infarto o necrosis grasa. Objetivo: Describir las características clínico-imagenológicas de un paciente con diagnóstico de apendangitis epiploica en el curso de su infección por COVID-19. Caso clínico: Paciente blanco, masculino de 48 años, con diagnóstico de COVID-19, que comenzó con cuadro de dolor abdominal difuso de 8 días de evolución, que se intensificó en las últimas 24 horas a nivel de la fosa iliaca derecha, acompañado de fiebre, estado nauseabundo y toma del estado general. Se le realiza rayos X de abdomen simple encontrándose íleo regional y tomografía axial computarizada con doble contraste, se halló el signo del halo hiperdenso compatible con apendangitis epiploica. Se decide tratamiento conservador. Se tiene en cuenta la comorbilidad con la COVID-19. Se le realizó seguimiento clínico-imagenológico con evolución favorable con la terapéutica impuesta. Desarrollo: La apendagitis epiploica es una causa de dolor abdominal infrecuente, que puede simular un cuadro de abdomen agudo. La evolución de esta enfermedad puede ser autolimitada por lo que se recomienda el manejo conservador. Conclusiones: Con la presente investigación se exponen los hallazgos clínicos-imagenológicos de la apendagitis epiploica, entidad poco conocida, que puede imitar un abdomen agudo quirúrgico y conllevar a una innecesaria intervención quirúrgica(AU)


Introduction: Epiploic appendagitis is an inflammatory process caused by structural damage due to torsion that generates hemorrhagic or ischemic areas, or by surrounding inflammation that affects the appendages and generates infarction or fat necrosis. Objective: describe the clinical-imaging characteristics of a patient diagnosed with epiploic appendangitis in the course of his COVID-19 infection. Clinical case report: We report the case of a white, 48-year-old male patient, diagnosed with COVID-19, who began with an 8-day history of diffuse abdominal pain, which intensified in the last 24 hours at the level of the right iliac fossa, accompanied by fever, nauseous state and taking of the general state. Simple abdominal X-rays were performed, finding regional ileus and computed tomography with double contrast, a hyperdense halo sign compatible with epiploic appendangitis was found. Conservative treatment is decided. Comorbidity with COVID-19 is taken into account. Clinical-imaging follow-up was carried out with favorable evolution with the imposed therapy. Development: Epiploic appendagitis is an infrequent cause of abdominal pain, which can simulate an acute abdomen. The evolution of this disease can be self-limited, so conservative management is recommended. Conclusions: This research disclosures the clinical-imaging findings of epiploic appendagitis, a little-known entity that can mimic an acute surgical abdomen and lead to unnecessary surgical intervention(AU)

ABSTRACT

Resumen Introducción: La enfermedad diverticular (ED) es una patología prevalente. Su incidencia ha aumentado, sin embargo, no se cuenta con publicaciones nacionales al respecto. Objetivo: Realizar un análisis de los egresos hospitalarios, edad de presentación, cirugías y letalidad por ED a nivel nacional entre el año 2003 y 2013. Materiales y Método: Se diseñó un estudio en base a datos publicados por la dirección y estadística e información de salud (DEIS) de Chile, entre los años 2003 y 2013. Se calcularon tasas de egreso hospitalarios por año, tasa de ED ajustada por sexo, tasas de intervención quirúrgica y letalidad. Resultados: El total de egresos hospitalarios presentó un alza desde 2.023 hasta 4.172 casos. La tasa de egresos por ED, en el total de la población, presentó un alza de 20 a 33 pacientes por cada 100.000 habitantes. La tasa de egresos hospitalarios presentó un alza de 173 hasta 327 pacientes por cada 100.000 egresos. La edad de presentación disminuyó de 62 a 58 años promedio. En cuanto a las cirugías, disminuyeron de 25% a 17%. La letalidad, es mayor sobre los 60 años y en el subgrupo que requiere cirugía. Discusión: Los resultados concuerdan con la literatura, se presenta un alza de hospitalizaciones, menor edad, menor requerimientos quirúrgicos y mayor letalidad en grupos etarios más avanzados. Conclusión: La enfermedad diverticular es una patología en aumento, desde el punto de vista hospitalario esto se hace evidente ante el crecimiento sostenido de egresos en el período estudiado.


Introduction: Diverticular disease (DD) is a prevalent pathology with multiple clinical manifestations. Its worldwide incidence has increased, however, there are no national publications in this regard. Aim: The objective of this study is to carry out an analysis of hospital discharges, age of presentation, surgeries and fatality due to DD from national data collected between 2003 and 2013. Materials and Method: A study was designed based on data from the management website and statistics and health information (DEIS) for Chile between 2003 and 2013. Hospital discharge rates per year, DD rate adjusted for sex, rates of surgical intervention and fatality were calculated. Results: The total of hospital discharges showed an increase from 2.023 to 4.172 cases. The discharge rate for DD in the total population increased from 20 to 33 patients per 100.000 inhabitants. The hospital discharge rate increased from 173 to 327 patients per 100.000 discharges. The age of presentation decreased from an average 62 to 58 years. Regarding surgeries, they decreased from 25% to 17%. Regarding mortality, it is higher over 60 years and in the surgical versus non-surgical subgroup. Discussion: These results are consistent with the literature; there is an increase in hospitalizations, lower age, lower surgical requirements and higher mortality in more advanced age groups. Conclusión: Diverticular disease is an increasing disease in the inpatient setting over the 10-year period studied.

ABSTRACT

Resumen Objetivo: Describir resultados de la cirugía de sustitución esofágica con tubo gástrico invertido, vía ascenso retroesternal en dos hospitales pediátricos durante el período marzo 2015 a marzo 2018. Materiales y Método: Un estudio observacional, transversal, con recolección de datos retrospectivo, donde se incluyeron todos los expedientes de pacientes que presentaban patología del esófago por causa adquirida o congénita que fueron operados de sustitución esofágica con tubo gástrico invertido en dos hospitales pediátricos durante 3 años. Resultados: Encontramos 29 niños sometidos a sustitución esofágica, de los cuales 27 cumplieron criterios de inclusión. La edad comprendida entre 2 y 17 años. El 63% corresponde al sexo femenino. La causa más frecuente de sustitución esofágica es por estenosis esofágica por ingesta caustica (92,59%). El 70% presentó algún tipo de complicación luego de la cirugía. La fístula esofagocutánea es la complicación principal con 33,33%. La permanencia en la unidad de cuidados intensivos es menor de 24 horas en un 74% de los niños. Se inicia la vía oral en casi la mitad de casos entre los 10-12 días de posquirúrgico, la estancia hospitalaria es en promedio 18,5 días. La mortalidad es 3,7%. Conclusión: La sustitución esofágica por tubo gástrico invertido vía ascenso retroesternal, es una técnica comparable en resultados a la interposición de colón. Para los autores, el estómago es un órgano ideal para realizar la reconstrucción esofágica, y sus complicaciones son manejables.


Aim: To describe the results of esophageal replacement surgery with an inverted gastric tube via retrosternal ascent in two pediatric hospitals during the period March 2015 to March 2018. Materials and Method: an observational, cross-sectional study with retrospective data collection that included all the records of patients with esophageal discontinuity due to acquired or congenital causes who underwent esophageal replacement surgery with an inverted gastric tube in two pediatric hospitals for 3 years. Results: We found 29 children undergoing esophageal replacement, of which 27 met inclusion criteria. The age between 2 to 17 years. 63% corresponds to the female sex. The most frequent cause of esophageal replacement is esophageal stricture due to caustic ingestion (92.59%). 70% presented some type of complication after surgery. The esophagocutaneous fistula is the main complication with 33.33%. The stay in the intensive care unit is less than 24 hours in 74% of children. The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

ABSTRACT

Introducción. A nivel mundial los tumores gastrointestinales tienen un impacto importante en la mortalidad y se asocian a diferentes factores, entre ellos regionales y sociodemográficos. El objetivo de este estudio fue describir la variación en el tiempo del cáncer gastrointestinal en una población del centro occidente de Colombia, dada su alta incidencia y desenlace frecuentemente fatal.Métodos. Se realizó un estudio retrospectivo observacional con muestreo no probabilístico en un tiempo de seis años. Se seleccionaron pacientes diagnosticados con algún tipo de neoplasia del tracto digestivo, en un hospital de tercer nivel del centro occidente de Colombia. Resultados. Se evaluaron un total de 1152 pacientes. Los tumores del tracto digestivo superior (esófago, unión esófago-gástrica y estómago) fueron los más frecuentes (44 %), seguidos de los tumores del tracto digestivo medio e inferior (intestino delgado, colon, recto y ano; 31 %) y de los tumores hepato-bilio-pancreáticos (25 %). La edad media de presentación fue 64,6 años, con una mayor frecuencia en el sexo masculino (51,6 %). El adenocarcinoma fue el tipo histológico más común.Conclusión. Los resultados de este estudio muestran que los tumores gastrointestinales son una neoplasia frecuente en nuestro país, siendo los tumores gástricos los que se presentan con mayor prevalencia, seguidos de los tumores colorrectales y las neoplasias biliopancreáticas, las cuales se mantiene en el tiempo.


Introduction. Worldwide, gastrointestinal tumors have a significant impact on mortality and are associated with different factors, including regional and sociodemographics. The objective of this study was to describe the variation over time of gastrointestinal cancer in a population from Central-Western Colombia, given its high incidence and frequently fatal outcome. Methods. An observational retrospective study with non-probabilistic sampling was carried out over a period of six years. Patients diagnosed with some type of neoplasm of the digestive tract were selected in a tertiary care hospital in the Central-Western Colombia. Results. A total of 1152 patients were evaluated. Tumors of the upper digestive tract (esophagus, esophagogastric junction, and stomach) were the most frequent (44%), followed by tumors of the middle and lower digestive tract (small intestine, colon, rectum and anus; 31%), and hepatobiliary-pancreatic tumors (25%). The mean age of presentation was 64.6 years with a higher frequency in males (51.6%). Adenocarcinoma was the most common histological type.Conclusion. The results of this study show that gastrointestinal tumors are a frequent neoplasm in our country, with gastric tumors being the most prevalent, followed by colorectal tumors and biliopancreatic neoplasms, which are maintained over time.

ABSTRACT

Introducción. A nivel mundial el cáncer colorrectal es la tercera causa de malignidad y la segunda causa de mortalidad por cáncer. En Colombia, tiene una prevalencia de 8,3 % dentro de las patologías neoplásicas, ubicándolo en el tercer lugar, después del cáncer de próstata y de mama, lo que lo cataloga como un problema de salud pública, por lo que es de gran importancia mantener datos actualizados acerca de su perfil epidemiológico. Métodos. Se realizó un estudio transversal en pacientes con cáncer colorrectal atendidos en el Hospital Universitario del Caribe, Cartagena, Colombia, durante el periodo 2015-2019. Se analizaron las variables sociodemográficas, clínicas, patológicas e histológicas. Resultados. Se encontraron un total de 268 pacientes atendidos por cáncer colorrectal, con predominio femenino en el (54,5 %) de los casos, y edad promedio de 62 años; con comorbilidades en 48,8 % y sintomatología de dolor abdominal en 56,7 %. El adenocarcinoma se encontró en el 82,1 % de los casos y la intervención más realizada fue la hemicolectomía derecha. Conclusión. El perfil epidemiológico del cáncer colorrectal encontrado en este estudio concuerda con los hallazgos de la literatura médica mundial, comprometiendo especialmente mujeres en nuestra institución.


Introduction. Worldwide, colorectal cancer is the third leading cause of malignancy and the second leading cause of cancer mortality. In Colombia, it has a prevalence of 8.3% within neoplastic pathologies, placing it in third place, after prostate and breast cancer, which classifies it as a public health problem, making it of great importance to maintain up-to-date data on its epidemiological profile. Methods. A cross-sectional study was carried out in patients with colorectal cancer treated at the Hospital Universitario del Caribe, Cartagena, Colombia, during the period 2015-2019. Sociodemographic, clinical, pathological and histological variables were analyzed. Results. A total of 268 patients treated for colorectal cancer were found, with a female predominance of 54.5% and an average age of 62 years; comorbidities in 48.8%, and symptoms of abdominal pain in 56.7%. Adenocarcinoma was found in 82.1% of cases and the most performed intervention was right hemicolectomy. Conclusion. The epidemiological profile of colorectal cancer found in this study is consistent with the findings of the world medical literature, especially involving women in our institution.

ABSTRACT

Abstract Aim: To locate and characterize colorectal adenomas endoscopically and histologically in a cohort of patients undergoing colonoscopy in Medellín, Colombia. Materials and methods: Descriptive cross-sectional study. We included patients older than 18 years who underwent colonoscopy between February and July 2020 at a specialized center in Medellín, Colombia. We determined the incidence of adenomas, their location in different segments of the colon, their endoscopic and histological characteristics, and cases of colorectal cancer (CRC) and high-grade dysplasia (HGD). Results: 992 colonoscopies were performed, finding colorectal polyps in 266 patients, of which 208 had adenomas. We resected 461 polyps, of which 336 were adenomas (72 %). The histological type with the highest representation was tubular (78 %). The location of adenomas was 37 % in the right colon, 25 % in the transverse colon, and 38 % in the left colon. CRC cases were nine per 1,000 patients, including advanced carcinoma and carcinoma in situ (HGD). Conclusions: Given the incidence of adenomas in the right and transverse colon, rectosigmoidoscopy is discouraged as a screening study for CRC. Tubular adenomas, sessile in appearance and tiny, predominated in the population studied. We recommend screening in the population over 40 years of age and the search for precursor lesions as strategies to reduce morbidity and mortality rates due to CRC.


Resumen Objetivo: localización y caracterización endoscópica e histológica de los adenomas colorrectales en una cohorte de pacientes sometidos a colonoscopia en Medellín, Colombia. Materiales y métodos: estudio descriptivo de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se determinó la incidencia de adenomas, su localización en los diferentes segmentos del colon, sus características endoscópicas e histológicas, así como también los casos de cáncer colorrectal (CCR) y displasia de alto grado. Resultados: se realizaron 992 colonoscopias y se encontraron pólipos colorrectales en 266 pacientes, de los cuales 208 tenían adenomas. En total se resecaron 461 pólipos, de los cuales 336 fueron adenomas (72 %). El tipo histológico con mayor representación fue el tubular (78 %). La localización de adenomas fue del 37 % en el colon derecho, 25 % en el transverso y 38 % en el colon izquierdo. La cantidad de casos de CCR fue de 9 por 1000 pacientes, que incluyen carcinoma avanzado y carcinoma in situ (DAG). Conclusiones: dada la incidencia de adenomas en el colon derecho y transverso, no se recomienda la rectosigmoidoscopia como estudio de tamizaje para CCR. En la población estudiada fueron predominantes los adenomas tubulares, de aspecto sésil y tamaño diminuto. Se recomienda el tamizaje en la población mayor de 40 años y la búsqueda de lesiones precursoras como estrategias para disminuir las tasas de morbimortalidad por CCR.

ABSTRACT

Abstract This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.


Resumo Este estudo teve como objetivo analisar o papel de fatores temporais, geográficos e sociodemográficos na mortalidade por câncer de próstata, mama, colo do útero, cólon, pulmão e esôfago nas capitais brasileiras (2000-2015). Estudo ecológico utilizando informações brasileiras de mortalidade. Modelos de Poisson multinível foram usados ​​para estimar o risco ajustado de mortalidade por câncer. Os níveis de mortalidade foram maiores em homens para câncer de cólon, pulmão e esôfago. As taxas de mortalidade foram mais altas nos idosos. Nossos resultados mostraram risco aumentado de mortalidade por câncer de cólon em ambos os sexos de 2000 a 2015, o que também foi evidenciado para câncer de mama e de pulmão em mulheres. Em ambos os sexos, o maior risco de mortalidade para câncer de pulmão e esôfago foi observado nas capitais do Sul. As capitais do Centro-Oeste, Sul e Sudeste apresentaram o maior risco de mortalidade por câncer de cólon tanto para homens quanto para mulheres. A taxa de mortalidade por câncer de cólon aumentou para ambos os sexos, enquanto a mortalidade por câncer de mama e de pulmão aumentou apenas para as mulheres. A região Norte apresentou a menor taxa de mortalidade por câncer de mama, colo do útero, cólon e esôfago. As regiões Centro-Oeste e Nordeste apresentaram as maiores taxas de mortalidade por câncer de próstata.

ABSTRACT

Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer in the United States and it is found in 17% of patients thought to have complicated diverticular disease. However, primary adenocarcinoma rarely occur in the colostomy site and the risk of developing malignancy is similar to that of any other colonic segment. Polyps found in CRC screenings can be divided into the following types: hyperplastic polyps, polyps with no malignant potential, adenomatous polyps, polyps with malignant potential, and malignancies. Local complications of the colostomy can appear in the immediate, early, or late postoperative period, with an incidence ranging from 15 to 30%; neoplasia is even less common. (AU)

ABSTRACT

Introduction: The gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Even though it can be found in any location of the digestive tract, the colorectal GIST is rare. With this study, we aim to review the current knowledge regarding the prognosis and management of colorectal GIST. Methods: A literature search was conducted in PubMed, and 717 articles were collected. After analyzing these studies, 60 articles were selected to use in this review. Results: The mitotic index, as well as tumor size and location were identified as good discriminators of prognosis in various studies. Surgery remains the only curative therapy for potentially resectable tumors. However, even after surgical resection, some patients develop disease recurrence and metastasis, especially those with highrisk tumors. Therefore, surgical resection alone might be inadequate for the management of all colorectal GISTs. The discovery of GIST's molecular pathway led to a shift in its therapy, insofar as tyrosine kinase inhibitors became part of the treatment schemes for this tumor, revolutionizing the treatment's outcome and prognosis. Discussion/Conclusion: The controversy concerning colorectal GIST prognosis and treatment can be, in part, attributed to the limited number of studies in the literature. In this review, we gathered the most recent knowledge about the prognosis and management of GIST in this rare location and propose two algorithms for its approach. Lastly, we highlight the importance of an individualized approach in the setting of a multidisciplinary team. (AU)

ABSTRACT

Resumen Objetivo: Comparar tres abordajes quirúrgicos (abierto, laparoscópico y laparoscópico convertido) para el manejo de complicaciones posoperatorias en cirugía colorrectal electiva realizadas primariamente por vía laparoscópica. Materiales y Método: Este estudio de cohorte retrospectivo incluyó pacientes reoperados después de una cirugía colorrectal laparoscópica electiva, agrupándose según la vía de abordaje de reoperación: abierta (RVA), laparoscópica (RVL) y laparoscópica convertida (RVLC). Las variables estudiadas fueron: preoperatorias (edad, sexo, puntuación ASA, IMC, comorbilidades e historia quirúrgica); operatorias (causa de reoperación, latencia para reoperación, tiempo operatorio, cirugía realizada y causa de conversión); y posoperatorias (tránsito intestinal, días de hospitalización, días de UCI, complicaciones médicas, infección del sitio quirúrgico, evisceración, transfusión y mortalidad a los 30 días). Resultados: Sin diferencias significativas para las variables preoperatorias y operatorias. En cuanto a las variables posoperatorias, el grupo de reoperaciones por vía laparoscópica, tuvo menos días de hospitalización (p = 0,012), menos días de UCI (p = 0,001) y un tránsito intestinal más rápido para reaparición de gases, heces y retorno a dieta sólida (p = 0,008, p = 0,029, p = 0,030, respectivamente). No hubo diferencias significativas en la infección del sitio quirúrgico, la evisceración, las complicaciones médicas, la transfusión y la mortalidad. Discusión y Conclusión: Este estudio reveló una mejor evolución clínica posoperatoria en el grupo de reoperación laparoscópica, con menor estancia hospitalaria y en UCI, y reducción del íleo posoperatorio, sin aumento de la morbimortalidad. Por lo tanto, la reoperación laparoscópica en cirugía colorrectal podría ser el abordaje más adecuado en pacientes debidamente seleccionados.


Aim: To compare three approaches (laparoscopic, open, and conversion of laparoscopic approach) for the management of intra-abdominal surgical complications after elective laparoscopic colorectal surgery. Materials and Method: This was a retrospective cohort study including patients who required reoperation due to an intra-abdominal surgical complication after initial elective laparoscopic colorectal surgery. Patients were grouped according to the reoperation approach-laparoscopic reoperation, laparoscopic reoperation that required conversion to open surgery, and open reoperation. Pre-operative variables (age, gender, ASA score, BMI, comorbidities, and surgical history), operative variables (cause of reoperation, latency for reoperation, operative time, surgery performed, and cause of conversion), and post-operative variables (intestinal transit, hospital days, ICU days, medical complications, surgical site infection, evisceration, transfusion and 30-day mortality), were compared between groups. Results: There were no significant differences between groups among the pre-operative and operative variables. In terms of post-operative variables, the laparoscopic reoperation group, had fewer hospital days (p = 0.012), fewer ICU days (p = 0.001), and faster intestinal transit regarding gas, stool and return to solid diet (p = 0.008, p = 0.029 and p = 0.030, respectively). However, there were no significant differences in surgical site infection, evisceration, medical complications, transfusion, and mortality. Discussion and Conclusión: This study revealed better post-operative clinical course in the laparoscopic reoperation group, with shorter hospital and ICU stay, and reduced postoperative ileus, without increased morbidity or mortality. Laparoscopic reoperation for complications after elective laparoscopic colorectal surgery may therefore be the preferred approach.

ABSTRACT

Melastoma malabathricum (M. malabathricum) extracts have been reported to exert various pharmacological activities including antioxidants, anti-inflammatory and antiproliferative activities. The objective of the present study was to determine the anticarcinogenic activity of its methanol extract (MEMM) against the azoxymethane (AOM)-induced early colon carcinogenesis in rats. Rats were randomly assigned to five groups (n=6) namely normal control, negative control, and treatment (50, 250 or 500 mg/kg of MEMM) groups. Colon tissues were harvested for histopathological analysis and endogenous antioxidant system determination. MEMM was also subjected to HPLC analysis. Findings showed that MEMM significantly (p<0.05) reversed the AOM-induced carcinogenicity by: i) reducing the formation of aberrant crypt foci (ACF) in colon tissues, and; ii) enhancing the endogenous antioxidant activity (catalase, superoxide dismutase and glutathione peroxidase). Moreover, various phenolics has been identified in MEMM. In conclusion, MEMM exerts the in vivo anticarcinogenic activity via the activation of endogenous antioxidant system and synergistic action of phenolics.


Se ha informado que los extractos de Melastoma malabathricum (M. malabathricum) ejercen diversas actividades farmacológicas, incluidas actividades antioxidantes, antiinflamatorias y antiproliferativas. El objetivo del presente estudio fue determinar la actividad anticancerígena de su extracto de metanol (MEMM) contra la carcinogénesis de colon temprana inducida por azoximetano (AOM) en ratas. Las ratas se asignaron al azar a cinco grupos (n=6), a saber, los grupos de control normal, control negativo y tratamiento (50, 250 o 500 mg/kg de MEMM). Tejidos de colon fueron recolectados para análisis histopatológico y determinación del sistema antioxidante endógeno. MEMM también se sometió a análisis de HPLC. Los hallazgos mostraron que MEMM invirtió significativamente (p<0.05) la carcinogenicidad inducida por AOM al: i) reducir la formación de focos de criptas aberrantes (ACF) en los tejidos del colon, y; ii) potenciar la actividad antioxidante endógena (catalasa, superóxido dismutasa y glutatión peroxidasa). Además, se han identificado varios fenólicos en MEMM. En conclusión, MEMM ejerce la actividad anticancerígena in vivo mediante la activación del sistema antioxidante endógeno y la acción sinérgica de los fenólicos.

ABSTRACT

La preparación intestinal se ha utilizado en cirugía de colon y recto por una variedad de razones, se cree que un colon limpio facilita la manipulación del intestino, permite el paso y disparo de engrapadoras quirúrgicas y permite la colonoscopia intraoperatoria, si es necesario. Sin embargo, el aspecto más estudiado y debatido de la preparación intestinal es su papel en la reducción de la morbilidad quirúrgica, es decir, las infecciones del sitio quirúrgico (ISQ). La cirugía de colon y recto tiene una de las tasas más altas de ISQ reportadas para todos los tipos de cirugía electiva, con revisiones recientes que muestran tasas que varían del 5,4% al 23,2%, con una media ponderada del 11,4%. (1). La preparación mecánica del intestino (PMI) se usó como un medio para disminuir la concentración bacteriana intraluminal con la esperanza de reducir las tasas de infección. Eventualmente, se agregaron antibióticos no absorbibles a las preparaciones intestinales para reducir aún más el contenido bacteriano intestinal(AU)


Bowel preparation has been used in colon and rectal surgery for a variety of reasons. A clean colon is thought to facilitate bowel manipulation, enable passage and firing of surgical staplers, and allow for intraoperative colonoscopy, if needed. The most studied and debated aspect of bowel preparation, however, is its role in reducing surgical morbidity, namely surgical site infections(SSIs). Colon and rectal surgery has among the highest rates of SSIs reported for all types of elective surgery, with recent reviews demonstrating rates varying from 5.4% to 23.2%, with a weighted mean of 11.4%(AU)

ABSTRACT

Los Schwannomas son tumores derivados de las células de Schwann de las vainas de los nervios periféricos. Se pueden localizar en cualquier región anatómica que contenga tejido nervioso periférico, siendo más frecuentes en la región craneofacial y las extremidades. Los Schwannomas pancreáticos son entidades sumamente infrecuentes de las cuales solo se han descrito 68 casos a nivel mundial. En el presente trabajo se presenta el caso de un paciente con hallazgo incidental de tres tumores sincrónicos dentro de los cuales se encuentra un Schwannoma pancreático.Caso clínico : Paciente femenino de 66 años de edad con antecedente de diabetes mellitus tipo 1 y enfermedad diverticular pancolónica quien acude presentando cuadro clínico compatible con absceso lumbar izquierdo. Se realiza TC de abdomen y pelvis con doble contraste que evidencia extensa área de colección heterogénea en región retroperitoneal que diseca hacia región lumbar y glútea izquierda, además de la presencia de tumor hipodenso de bordes lobulados en mesogastrio. Se realiza colonoscopia que reporta lesión exofítica ulcerada en unión rectosigmoidea. El resto de paraclínicos y estudios de extensión se encontraban dentro de límites normales. Se decide resolución quirúrgica mediante drenaje percutáneo de absceso y laparotomía exploradora. Informe histopatológico: cistoadenoma seroso microquístico de cuerpo de páncreas, Schwannoma de cola de páncreas y adenocarcinoma moderadamente diferenciado de colon sigmoides.Conclusión : Los Schwannomas pancreáticos son entidades sumamente infrecuentes que pueden presentarse con una amplia variedad de manifestaciones clínicas, sin embargo, deben tenerse en cuenta como posible diagnóstico diferencial ante el hallazgo de un tumor pancreático(AU)


Schwannomas, also called Neurilemmomas or Neurinomas, are tumors derived from Schwann cells of the peripheral nerve sheaths. They can be located in any anatomical region that contains peripheral nervous tissue, being more frequent in the craniofacial region and the extremities. Pancreatic Schwannomas are extremely rare entities of which only 68 cases have been described worldwide. In the present study we present the case of a patient with an incidental finding of three synchronous tumors, including a pancreatic Schwannoma.Clinical case : A 66-year-old female patient with a history of type 1 diabetes mellitus and pancolonic diverticular disease who presented with symptoms compatible with left lumbar abscess. A double-contrast CT of the abdomen and pelvis was performed, which revealed a large area of heterogeneous collection in the retroperitoneal region that dissected towards the left lumbar and gluteal region, in addition to the presence of a hypodense tumor with lobulated borders in the mesogastrium. A colonoscopy was performed, which reported an ulcerated exophytic lesion at the rectosigmoid junction. The rest of the paraclinical and extension studies were within normal limits. Surgical resolution is decided by percutaneous abscess drainage and exploratory laparotomy. Histopathological report: microcystic serous cystadenoma of the body of the pancreas, Schwannoma of the pancreas tail, and moderately differentiated adenocarcinoma of the sigmoid colon.Conclusion : Pancreatic Schwannomas are extremely rare entities that can present with a wide variety of clinical manifestations, however, they should be taken into account as a possible differential diagnosis when a pancreatic tumor is found(AU)

ABSTRACT

OBJECTIVE@#To investigate the effect of Enterococcus faecium QH06 on TNBS-induced ulcerative colitis (UC) in rats and explore the mechanisms in light of intestinal flora and intestinal immunity.@*METHODS@#Thirty-six male Wistar rats were randomized equally into control group, UC model group, and E.faecium QH06 intervention group. The rats in the latter two groups were subjected to colonic enema with 5% TNBS/ethanol to induce UC, followed by treatment with intragastric administration of distilled water or E.faecium QH06 at the dose of 0.21 g/kg. After 14 days of treatment, the rats were examined for colon pathologies with HE staining. The mRNA and protein expression levels of IL-4, IL-10, IL-12, and IFN-γ in the colon tissues were detected using RT-qPCR and ELISA, and the expression of TLR2 protein was detected with immunohistochemistry and ELISA. Illumina Miseq platform was used for sequencing analysis of the intestinal flora of the rats with bioinformatics analysis. The correlations of the parameters of the intestinal flora with the expression levels of TLR2 and cytokines were analyzed.@*RESULTS@#The rats with TNBS- induced UC showed obvious weight loss (P < 0.01) and severe colon tissue injury with high pathological scores (P < 0.01). The protein expression levels of IFN-γ, IL-12, and TLR2 (P < 0.01) and the mRNA expression levels of IFN-γ, IL-12 and IL-10 (P < 0.05) were significantly increased in the colon tissues of the rats with UC. Illumina Miseq sequence analysis showed that in UC rats, the Shannon index (P < 0.05) ACE (P < 0.01)and Chao (P < 0.05) index for the diversity of intestinal flora both decreased with a significantly increased abundance of Enterobacteriaceae (P < 0.01) and a lowered abundance of Burkholderiaceae (P < 0.05). Compared with the UC rats, the rats treated with E. faecium QH06 showed obvious body weight gain (P < 0.05), lessened colon injuries, lowered pathological score of the colon tissue (P < 0.05), decreased protein expressions of IFN- γ, IL- 12, and TLR2 and mRNA expressions of IFN- γ and IL-12 (P < 0.01 or 0.05), and increased protein expressions of IL- 4 (P < 0.05). The Shannon index ACE (P < 0.05) and Chao (P < 0.05) index of intestinal microflora were significantly increased, the abundance of Enterobacteriaceae was lowered and that of Burkholderiaceae and Rikenellaceae was increased in E.faecium QH06- treated rats (P < 0.01 or 0.05). Correlation analysis showed that IFN-γ was positively correlated with the abundance of Enterobacteriaceae, and IFN-γ was negatively correlated with the abundance of Prevotellaceae, Desulfovibrionaceae, norank_o_Mollicutes_RF39 and Clostridiales_vadinBB60_group; TLR2 was negatively correlated with Clostridiales_vadinBB60_group, norank_o_Mollicutes_RF39 and Prevotellaceae.@*CONCLUSION@#E.faecium QH06 can alleviate TNBS-induced colonic mucosal injury in rats, and its effect is mediated possibly by increasing the abundance of SCFA-producing bacteria such as Prevotellaceae and inhibiting abnormal immune responses mediated by TLR2.

ABSTRACT

Ulcerative colitis (UC) is a chronic and recurrent inflammatory bowel disease (IBD) that has become a major gastroenterologic problem during recent decades. Numerous complicating factors are involved in UC development such as oxidative stress, inflammation, and microbiota disorder. These factors exacerbate damage to the intestinal mucosal barrier. Spirulina platensis is a commercial alga with various biological activity that is widely used as a functional ingredient in food and beverage products. However, there have been few studies on the treatment of UC using S. platensis aqueous extracts (SP), and the underlying mechanism of action of SP against UC has not yet been elucidated. Herein, we aimed to investigate the modulatory effect of SP on microbiota disorders in UC mice and clarify the underlying mechanisms by which SP alleviates damage to the intestinal mucosal barrier. Dextran sulfate sodium (DSS) was used to establish a normal human colonic epithelial cell (NCM460) injury model and UC animal model. The mitochondrial membrane potential assay 3-‍‍(4,5-dimethylthiazol-2-yl)-2,‍5-diphenyltetrazolium bromide (MTT) and staining with Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) and Hoechst 33258 were carried out to determine the effects of SP on the NCM460 cell injury model. Moreover, hematoxylin and eosin (H&E) staining, transmission electron microscopy (TEM), enzyme-linked immunosorbent assay (ELISA), quantitative real-time polymerase chain reaction (qPCR), western blot, and 16S ribosomal DNA (rDNA) sequencing were used to explore the effects and underlying mechanisms of action of SP on UC in C57BL/6 mice. In vitro studies showed that SP alleviated DSS-induced NCM460 cell injury. SP also significantly reduced the excessive generation of intracellular reactive oxygen species (ROS) and prevented mitochondrial membrane potential reduction after DSS challenge. In vivo studies indicated that SP administration could alleviate the severity of DSS-induced colonic mucosal damage compared with the control group. Inhibition of inflammation and oxidative stress was associated with increases in the activity of antioxidant enzymes and the expression of tight junction proteins (TJs) post-SP treatment. SP improved gut microbiota disorder mainly by increasing antioxidant enzyme activity and the expression of TJs in the colon. Our findings demonstrate that the protective effect of SP against UC is based on its inhibition of pro-inflammatory cytokine overproduction, inhibition of DSS-induced ROS production, and enhanced expression of antioxidant enzymes and TJs in the colonic mucosal barrier.

ABSTRACT

The present study investigated the effect of Euphorbiae Pekinensis Radix(EPR) on intestinal flora structure before and after vinegar processing and explored the detoxification mechanism of vinegar-processed EPR. In this study, the extraction efficiency of casbane diterpenes from EPR with different solvents was investigated, and the optimal solvent was selected to enrich these components. After 14 days of intragastric administration of total diterpene extract of EPR and vinegar-processed EPR, 16 S rDNA sequencing technology was used to detect the structural changes of intestinal flora. The flora related to the intestinal toxicity of EPR was screened out based on the results of intestinal pathological damage by correlation analysis. The results showed that Soxhlet extraction with chloroform as extraction solvent could enrich Casbane diterpenes in EPR. As revealed by 16 S rDNA sequencing results, EPR could significantly change the structure of intestinal flora, which could be reversed by vinegar-processing EPR. Some intestinal flora candidates might be related to detoxification of vinegar processing. The correlation analysis of intestinal flora candidates and indexes related to intestinal mucosal injury showed that compared with EPR, vinegar-processed EPR could down-regulate the abundance of some pathogenic bacteria such as Mucispirillum, Bilophila, and Ruminiclostridium, and up-regulated some probiotics such as Enterorhabdus, Ruminococcaceae_UCG-014, Barnesiella, and Candidatus. The intestinal toxicity caused by EPR may be related to the disturbance of intestinal flora, and vinegar-processed EPR can improve intestinal flora disorder by up-regulating the abundance of probiotics and down-regulating the abundance of pathogenic bacteria to remodel the intestinal mucosal barrier and reduce toxicity.
