ABSTRACT

Resumen Introducción: la hiperplasia nodular linfoide del colon se define como > 10 nódulos linfoides visibles en colonoscopia. No existen estudios de su validez al compararlo con la histopatología. Objetivos: determinar la validez del hallazgo de nódulos en colonoscopia para el diagnóstico de hiperplasia nodular linfoide. Material y métodos: estudio prospectivo de prueba diagnóstica. Se incluyeron colonoscopias realizadas consecutivamente de 2014 al 2018 con equipos Olympus PCFQ150AI y GIFXP150N con obtención de biopsias. El criterio endoscópico fue la presencia de > 10 nódulos de 2 a 10 mm y el criterio histológico fue hiperplasia de folículos linfoides y mantos de linfocitos en lámina propia o submucosa. Los datos se analizaron en Epidat3.1. Se obtuvo la sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y negativo (VPN), y coeficientes de probabilidad positivo (LR+) y negativo (LR-) con sus intervalos de confianza. Resultados: se incluyeron 327 colonoscopias, la mediana de edad fue de 84 meses. La principal indicación para la colonoscopia fue sangrado digestivo bajo (38,8%). El hallazgo de nódulos se encontró en el 21% y el sitio de mayor frecuencia fue el colon total (46%), mientras que por histopatología se encontró hiperplasia nodular linfoide en el 38%. El hallazgo de nódulos obtuvo una S de 32% (intervalo de confianza [IC] del 95%: 24-140), E de 84% (IC 95%: 79-89), VPP de 56% (IC 95%: 44-68), VPN de 67% (IC 95%: 61-72), LR+ de 2,04 (IC 95%: 1,4-3) y LR- de 0,8 (IC 95%: 0,8-0,9). Conclusiones: la validez diagnóstica del hallazgo de nódulos en colonoscopia para hiperplasia nodular linfoide es pobre, por lo que la toma de biopsia debe recomendarse siempre.


Abstract Introduction: Nodular lymphoid hyperplasia of the colon is characterized by the presence of >10 lymphoid nodules visible in colonoscopy. There are no studies that confirm their validity when compared with histopathology. Objective: To determine the validity of nodules detected at colonoscopy for the diagnosis of nodular lymphoid hyperplasia in children. Materials and methods: Prospective study of diagnostic test accuracy. Colonoscopies performed consecutively from 2014 to 2018 using Olympus PCFQ150AI and GIFXP150N biopsy machines were included. The endoscopic criterion was the presence of >10 nodules from 2 to 10mm of diameter, while the histological criterion was presence of follicular lymphoid hyperplasia and lymphocyte mantles in lamina propia or submucosa. Data were analyzed in Epidat3.1. Sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-) were obtained with their corresponding confidence intervals. Results: 327 colonoscopies were included; the median age was 84 months. The main indication for colonoscopy was lower gastrointestinal bleeding (38.8%). Nodules were found in 21% of the patients, predominantly throughout the whole colon (46%), whereas histopathology found nodular lymphoid hyperplasia in 38%. SE for the finding of nodules was 32% (95% confidence interval [CI]: 24-140), SP was 84% (95% CI: 79-89), PPV was 56% (95% CI: 44-68), NPV was 67% (95% CI: 61-72), LR+ was 2.04 (95% CI: 1.4-3) and LR- was 0.8 (95% CI: 0.8-0.9). Conclusions: The validity of the presence of nodules on colonoscopy for the diagnosis of nodular lymphoid hyperplasia is poor, so biopsy should always be performed.

ABSTRACT

Resumen La malacoplaquia es una enfermedad inflamatoria rara, granulomatosa y crónica, caracterizada por infiltrados agregados de histiocitos conocidos como inclusiones de Michaelis-Gutmann. El sistema urinario es el sitio afectado más común, seguido del tracto gastrointestinal. El pronóstico de la enfermedad depende de la extensión, la localización y la salud subyacente del paciente. Caso: se describe un caso clínico de un paciente masculino de 15 años de edad, sin antecedentes de salud de importancia, que inicialmente presenta la enfermedad a partir de los 7 años con hematoquecia y dolor abdominal de leve intensidad que mejoraba después de la defecación. Se realizó una colonoscopia en la que se visualizaron lesiones pseudopolipoideas en el colon sigmoide, las cuales fueron biopsiadas y reportaron pólipos inflamatorios con focos de agudización, numerosos histiocitos (cuerpos de Michaelis-Gutmann) y cambios reactivos del epitelio que diagnosticaron malacoplaquia. Conclusión: la malacoplaquia es una enfermedad muy rara en personas jóvenes sin enfermedad subyacente. Su prevalencia es desconocida, pero se han descrito más de 700 casos. Puede darse en todas las edades, con edad media al diagnóstico de 50 años. Los casos pediátricos son raros. Existe una mayor incidencia en hombres y no tiene predilección por la raza. El 60% a 80% de los casos afecta al tracto urinario (vejiga, riñones y uretra); el 15%, al tracto digestivo (colon izquierdo, sigma, recto y estómago); y en menor porcentaje, otras zonas menos frecuentes como piel, pulmones y sistema nervioso central. El pronóstico de la enfermedad es generalmente bueno. Presentamos un caso de un joven sano de 15 años de edad sin enfermedad asociada evidente, que ilustra la rareza de esta presentación y la necesidad de un alto nivel de sospecha clínica para diagnosticar la enfermedad.


Abstract Malacoplakia is a rare, granulomatous, chronic inflammatory disease characterized by foamy histiocytic infiltrations known as Michaelis-Gutmann inclusions. The urinary system is the most commonly affected site, followed by the gastrointestinal tract. The prognosis of the disease depends on the extent, location, and underlying health status of the patient. This is the clinical case of a 15-year-old male patient with no significant health history. At age 7, the patient presented with hematochezia and mild abdominal pain that improved after defecation. A colonoscopy was performed, finding pseudopolypoid lesions in the sigmoid colon. Biopsy samples were taken, and the report showed inflammatory polyps with exacerbation foci, numerous histiocytes (Michaelis-Gutmann bodies), and reactive epithelial changes that lead to diagnose malacoplakia. Conclusion: Malacoplakia is a very rare disease in young people with no underlying disease. Its prevalence is unknown, but more than 700 cases have been reported. It can occur at all ages, with a mean age at diagnosis of 50 years. Pediatric cases are rare. There is a higher incidence in men, and it has no racial predilection. Between 60% and 80% of cases involve the urinary tract (bladder, kidneys, and urethra); 15% involve the digestive tract (left colon, sigmoid colon, rectum, and stomach); and, to a lesser extent, other areas such as skin, lungs, and central nervous system may be affected. The prognosis of the disease is usually good. This is the case of a healthy 15-year-old male with no apparent associated disease that illustrates the rarity of this presentation and the need for a high level of clinical suspicion to diagnose the disease.

ABSTRACT

Abstract Introduction Colorectal cancer is the second most common type of cancer and the third leading cause ofmortality due to cancers. Anastomosis leak after proctectomy is a dangerous complication that must be managed carefully. The aim of the present study was to assess the procedure of resection and pull-through of the new rectum after anastomosis leak in patients after proctectomy. Methods and Materials This was a cross-sectional study. Patients who visited the Firoozgar Hospital between 2015 and 2018 for rectal cancer surgery and had anastomosis leak entered the study. All patients underwent resection of the residue of rectum and pull-through of colon. Results In the present study, out of the 110 cases who underwent proctectomy, 12 patients with postoperative anastomosis leak were reported. Five (41.7%) were male and 7 (58.3%) were female. Themean age of the patients was 41.5 ± 4.3 years (33-51). Resection of the new rectum and pull-through anastomosis were performed for these 12 patients. No major intraoperative complication occurred. Postoperative course was uneventful in all patients. Discussion Resection of residue of rectum and pull-through in patients with anastomosis leak can be done after rectal cancer surgery. This method is superior to abdominopelvic resection in many aspects, especially regarding accessibility to the new rectum by rectal exam or endosonography to assess recurrence or a relative continence after closure of ostomy.


Resumo Introdução O câncer colorretal é o segundo tipo de câncer mais comum, e a terceira principal causa de mortalidade por câncer. O vazamento da anastomose após a proctectomia é uma complicação perigosa, que deve ser tratada com cuidado. O objetivo do presente estudo foi avaliar o procedimento de ressecção e abaixamento do novo reto após vazamento de anastomose em pacientes submetidos à proctectomia. Métodos e Materiais Este foi um estudo transversal que incluiu pacientes que compareceram ao Firoozgar Hospital entre 2015 e 2018 submetidos a cirurgia de câncer retal e com vazamento de anastomose. Todos os pacientes foram submetidos a ressecção do resíduo do reto e abaixamento do cólon. Resultados No presente estudo, dos 110 casos submetidos a proctectomia, 12 pacientes tiveram vazamento de anastomose pós-operatório: 5 (41,7%) do sexo masculino e 7 (58,3%) do sexo feminino. A idade média dos pacientes foi de 41,5 ± 4,3 anos (gama: 33 a 51 anos). A ressecção do reto novo e a anastomose por abaixamento foram realizadas nesses 12 pacientes. Nenhuma complicação intraoperatória mais grave ocorreu. No pós-operatório, não houve intercorrências em nenhum dos pacientes. Discussão A ressecção de resíduo retal e o abaixamento em pacientes com vazamento de anastomose pode ser feita após cirurgia de câncer retal. Este método é superior à ressecção abdominopélvica em muitos aspectos, especialmente quanto à acessibilidade ao novo reto por exame retal ou endossonografia para avaliar a recorrência ou uma continência relativa após o fechamento da ostomia.

ABSTRACT

Background Intestinal duplications are rare congenital developmental anomalies with an incidence of 0.005-0.025% of births. They are usually identified before 2 years of age and commonly affect the foregut or mid-/hindgut. However, it is very uncommon for these anomalies, to arise in the colon or present during adulthood. Case presentation Herein, we present a case of a 28-year-old woman with a long-standing history of constipation, tenesmus, and rectal prolapse. Colonoscopy results were normal. An abdominal computed tomography (CT) revealed a diffusely mildly dilated redundant colon, which was prominently stool-filled. The gastrografin enema showed ahaustral mucosal appearance of the sigmoid and descending colon with findings suggestive of tricompartmental pelvic floor prolapse, moderate-size anterior rectocele, and grade 2 sigmoidocele. A laparoscopic exploration was performed, revealing a tubular duplicated colon at the sigmoid level. A sigmoid resection rectopexy was performed. Pathologic examination supported the diagnosis. At 1-month follow-up, the patient was doing well without constipation or rectal prolapse. Conclusions Tubular colonic duplications are very rare in adults but should be considered in the differential diagnosis of chronic constipation refractory to medical therapy. Due to the non-specific manifestations of this entity, it is rather challenging to make an accurate diagnosis pre-operatively. Surgery remains the mainstay of treatment. Some reports suggest that carcinomas are more prone to develop in colonic/rectal duplications than in other GI tract duplications.

ABSTRACT

Dendrobium officinale is a sacred product for nourishing Yin and has a clear "thick gastrointestinal" effect. Modern pharmacological studies had found that it could improve gastrointestinal function. This study observed the improvement effect of D. officinale on constipation model mice with Yin deficiency caused by warm-drying medicine. It provided experimental basis for the treatment of Yin deficiency constipation. The male and female ICR mice were randomly divided into normal group, model group, D. officinale high, medium and low dose groups(0.6, 0.4, 0.2 g·kg~(-1)), and phenolphthalein tablets group. The model mice of Yin deficiency constipation were established by gavage with warm-drying medicine. The overall state and body temperature of the mice were observed and recorded. The number of feces, feces weight, fecal moisture content and intestinal propulsion were measured. The morphological damage of colon tissue was observed by hematoxylin-eosin(HE) staining. The expression of inducible nitric oxide synthase(iNOS) in the colon was detected by Western blot and immunohistochemical method. The expression of iNOS mRNA in the colon was detected by Real-time fluorescence quantitative PCR, and the serum cyclic guanosine phosphate(cGMP) level was detected the enzyme-linked immunosorbent assay(ELISA). The results showed that D. candidum could reduce the body temperature of mice with Yin deficiency constipation, increase the number of feces, wet feces, dry feces and intestinal propulsion ability, reduce the expression of iNOS protein and mRNA in the colon, and reduce the content of cGMP in the serum. It showed that D. candidum could improve the symptoms of Yin deficiency constipation mice caused by warm-drying medicine, and the mechanism may be related to reducing the expression of iNOS in the colon and increasing intestinal motility.

ABSTRACT

This paper was to investigate the effect of Huanglian Jiedu Decoction(HLJD) on ulcerative colitis(UC) in mice, and determine the effective components in plasma, and virtually screen its therapeutic target, and predict its mechanism. Sixty Balb/c mice were randomly divided into blank group, model group, mesalazine treatment group(0.3 g·kg~(-1)), and HLJD treatment groups(24.66, 12.33, 6.17 g·kg~(-1)). Excepted for the blank group, all the mice in HLJD and mesalazine treatment groups were gavage administration. All mice freely drank 2.5% DSS solution for seven days to induce UC. The disease activity index(DAI) was detected each day. At the end of the experiment, HE staining was used to observe the pathological changes in colon. The content of IL-1β, IL-6 and TNF-α in colon were determined by ELISA. The effective components in plasma were determined by UPLC-Q-TOF-MS. The reverse docking in PharmMapper was used to screen the component targets. The disease targets of UC were collected by searching TTD, OMIM and GeneCards databases. The intersection of the component targets and disease targets was selected as the therapeutic targets. Then the therapeutic targets were imported into the STRING for GO and KEGG enrichment analysis. Discovery Studio was used to simulate the docking between the components and the targets. RESULTS:: showed that the DAI in the model group increased significantly(P<0.05), and the number of inflammatory cells and infiltration degree increased significantly compared with the blank group. The DAI in HLJD treatment group was significantly reduced(P<0.05), and the number and infiltration degree of inflammatory cells were reduced compared with the model group. The ELISA results showed that the levels of IL-1β, IL-6 and TNF-α were increased significantly in the model group(P<0.01) compared with the blank group, and significantly down regulated in the HLJD treatment group(P<0.05) compared with the model group. After UPLC-Q-TOF-MS analyse, ten components were identified. The network pharmacology analysis showed that the action targets were significantly enriched in 129 of biological processes, such as response to organic substance, chemical and oxygen-containing compound, etc., as well as 16 of signal pathways, such as IL-17, TNF and hepatitis B signal pathways, were enriched too. The results of molecular docking showed that limonin, palmatine and berberine could bind to CASP3 and MMP9 by hydrogen bond. In conclusion, HLJD could alleviate the colonic mucosal inflammatory infiltration and mucosal damage in UC mice. The mechanism may be related to the anti-inflammatory effect on UC mice by reducing the levels of IL-1β, IL-6 and TNF-α in colon through limonin, palmatine and berberine regulating IL-17 signal pathway and TNF signal pathway via CASP3 and MMP9 meditated.

ABSTRACT

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


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

ABSTRACT

RESUMEN Antecedentes: la fístula anastomótica (FA) es una de las complicaciones más severas de la cirugía colo rrectal. Su desarrollo obedece a múltiples factores dependientes del paciente y la técnica operatoria; entre estos últimos podemos mencionar la vascularización de los cabos como uno de los principales. La angiografía fluorescente (AF) permite la evaluación de ese factor en tiempo real durante la cirugía. Objetivo: describir la experiencia en el uso de la AF durante la cirugía colorrectal en un Hospital Uni versitario de la ciudad de Buenos Aires, registrar el cambio de conducta quirúrgica inducido por el uso de la AF y la incidencia de FA. Material y métodos: entre enero de 2016 y junio de 2018 se incluyeron 37 pacientes sometidos a resecciones colónicas programadas y con evaluación de la perfusión con AF. Resultados: la AF pudo realizarse en todos los pacientes con un tiempo operatorio extra de 3 a 9 mi nutos, registrando un cambio de conducta en 4 (10,81%) pacientes. Se registraron 2 (5,41%) fístulas anastomóticas. Conclusiones: la AF con verde de indocianina durante la cirugía colorrectal fue factible, sumó mínima complejidad y tiempo a la operación tradicional, y permitió cambiar la conducta en la sección intestinal en el 11% de los casos, con baja tasa de fístulas anastomóticas.


ABSTRACT Background: Anastomotic leak (AL) is one of the most feared complication of colorectal surgery. Its development is dependent of patient and surgery factors. Of these, bowel perfusion is one of the most important. Fluorescent angiography (FA) allows the identification in real time of the bowel perfusion. Objective: to describe the experience in the use of FA during colorectal surgery in a University Hospital setting in Buenos Aires, to register the change in surgical plan according to the FA findings and record the incidence of AL. Material y methods: Between January 2016 and June 2018, 37 patients with scheduled colorectal resections and FA bowel perfusion assessment were included. Results: Perfusion assessment with FA was possible in all cases with an extra operative time of 3 to 9 minutes, a change in surgical plan was registered in 4 cases (10.81%) and 2 AL were recorded (5.41%). Conclusions: FA during colorectal surgery is feasible, with minimum extra operative time and results in a change in surgical plan in 11% of the cases, and low rate of anastomotic fistula.

ABSTRACT

Abstract Introduction: Minimally invasive colectomy has been performed for some years for many patients worldwide without much complications compared to the open approach. In this study we explained our experience regarding a modification in laparoscopic total colectomy and removing the specimen with Natural Orifice Specimen Extraction (NOSE) through rectum using a plastic cover for the first time. Methods and material: This was an experimental study on a new technique of total colectomy with a small modification. Total colectomy was performed based on 7 port laparoscopic approach. Rectum was sparred. Colon was then taken out through the anal canal using a plastic cover. Results: Thirteen patients underwent laparoscopic total colectomy by removal of the specimen through rectum. Mean age of patients was 42.23 ± 8.15 years. Mean duration of operation was 130 ± 32.4 min. All patients had an uneventful postoperative hospitalization. Discussion: Laparoscopic total colectomy has been proven to have superior benefits than the open approach. In NOSE technique, colon is removed from the anal canal without any complication or consuming much time. This technique might have less pain and removes the complications associated with an incision on the skin to remove the specimen. Also, due to low price of a usual plastic cover, it can be used instead of other techniques to remove the specimen through the rectum.


Resumo Introdução: A colectomia minimamente invasiva vem sendo realizada há alguns anos em muitos pacientes no mundo inteiro, apresentando menos intercorrências do que a abordagem aberta. Neste estudo, os autores relatam sua experiência com uma modificação da colectomia total laparoscópica e extração de espécime em orifício natural (NOSE) pelo reto, usando uma cobertura plástica pela primeira vez. Métodos e materiais: Este foi um estudo experimental sobre uma nova técnica de colectomia total com uma pequena modificação. A colectomia total foi realizada com base na abordagem laparoscópica de sete portas. O reto foi poupado. O cólon foi então retirado pelo canal anal usando uma cobertura plástica. Resultados: Treze pacientes foram submetidos a colectomia total laparoscópica por remoção do espécime pelo reto. A idade média dos pacientes foi de 42,23 ± 8,15 anos. A duração média da operação foi de 130 ± 32,4 minutos. Para todos os pacientes, a internação pós-operatória transcorreu sem intercorrências. Discussão: Foi comprovado que a colectomia total laparoscópica apresenta benefícios superiores à abordagem aberta. Na técnica NOSE, o cólon é removido mais rapidamente do canal anal, sem nenhuma intercorrência. Essa técnica pode causar menos dor e remove as complicações associadas a uma incisão na pele para remover o espécime. Além disso, devido ao baixo preço de uma cobertura plástica comum, ela pode ser usada no lugar de outras técnicas para remover o espécime pelo reto.

ABSTRACT

Resumen La diverticulosis es una entidad que predomina en países occidentales. Su prevalencia aumenta con la edad, presentándose en aproximadamente el 80% de la población mayor de 85 años. Los divertículos colónicos adquiridos son herniaciones saculares de la mucosa y submucosa (pseudodivertículos) y predominan en sigma, en países occidentales; los congénitos poseen las tres capas parietales (divertículos verdaderos) y predominan en colon derecho, en países asiáticos. Aproximadamente un 10%-25% de dichos pacientes con diverticulosis presentarán a lo largo de su vida un cuadro de diverticulitis aguda, representando una de las causas más frecuentes de abdomen agudo (3,8%). Clínicamente, se expresa por dolor abdominal en fosa ilíaca izquierda (excepción en dolicosigma/divertículos congénitos derechos) y pueden presentar complicaciones como flemones, abscesos, pileflebitis, peritonitis, con consiguiente riesgo de vida. La tomografía computada (TC) permite el diagnóstico oportuno, identificación de complicaciones y planificación terapéutica. A dicho fin se establecieron diferentes clasificaciones y modificaciones, siendo la más reconocida la propuesta por Hinchey (modificada por Wasvary y col., Kaiser y col.) y otras estableciendo correlaciones con el tratamiento, como la propuesta por Sartelli y col. El objetivo del presente estudio es realizar una revisión iconográfica de esta última (Sartelli y col.) y evaluar sus implicancias terapéuticas.


Abstract Diverticular disease is an entity with high prevalence in western countries that increases with age, and affects approximately 80% of the population over 85 years of age. Acquired colonic diverticula are saccular mucosal and submucosal herniation (pseudodiverticles) and predominate in sigma, in western countries; the congenital ones possess the three parietal layers (true diverticula) and predominate in right side colon, in Asian countries. Approximately 10%-25% of patients with colonic diverticulosis, in their lifetime will present an episode of acute diverticulitis, which represents one of the most frequent causes of acute abdominal pain (3.8%). Clinically it express by abdominal pain in the left iliac fossa (exception in dolicosigma / right congenital diverticula) and may present complications such as phlegmon, abscesses, pylephlebitis, peritonitis, life threatening conditions. Computed tomography (CT) allows timely diagnosis, identification of complications and therapeutic planning. To this end, several classifications have been used, from which Hinchey's is the most renown (modified by Wasvary et al, Kaiser et al.), and other ones establish therapeutic correlation such as the one proposed by Sartelli et al. The objective of the present study is to make an iconographic review of this last one (Sartelli et al.) and to evaluate its therapeutic implications.

ABSTRACT

O aumento da incidência de câncer na população brasileira alerta para a necessidade de implantação de medidas de rastreamento baseadas na busca ativa de novos casos. Neste sentido, o presente trabalho avaliou o impacto de um programa itinerante de rastreamento dos cânceres de mama, colo de útero, próstata e pele realizado pelo Serviço Social da Indústria (Sesi) no período de 1 ano, em 22 municípios do estado do Paraná. O estudo é descritivo, com banco de dados secundários e abordagem quantitativa, referente ao programa Cuide-se Mais do Sesi Paraná. Através de uma unidade móvel, foram realizadas análises da superfície da pele, coleta de Papanicolau em mulheres de 25 a 69 anos, mamografia em mulheres com idade entre 40 e 69 anos e dosagem de Antígeno Prostático Específico (PSA) em homens de 45 a 69 anos de 22 municípios do Paraná. Foram atendidos 4679 trabalhadores paranaenses em 202 empresas, realizadas 4120 palestras de orientações e 1346 oficinas de prevenção. As lesões avaliadas em pele suspeitas para câncer corresponderam a 3,4% do total de 3054 exames. Foram realizadas 873 mamografias, e encaminhados 11 casos de lesões suspeitas no exame de Papanicolau de um total de 2073 coletas. O PSA esteve alterado em 8 homens de um total de 1308 exames. A instalação da unidade móvel dentro da empresa quebra duas barreiras de impedimento dos trabalhadores realizarem seus exames preventivos: a sociocultural e a institucional. Desta forma, programas e ações de rastreamento do câncer podem contribuir para o diagnóstico precoce desta patologia, especialmente na população em idade economicamente produtiva.(AU)


The increased incidence of cancer in the Brazilian population urges the need of implementing screening measures based on the active search for new cases. In this sense, the present work presents the results of the Take More Care disease-screening program. With a mobile unit, analyzes of the skin surface, Pap smear collection in women aged 25 to 69 years, mammography in women aged 40 to 69 years and specific prostatic antigen (SPA) in men aged 45 to 69 were performed in 22 municipalities of Paraná state. 4679 workers from Paraná were attended in 202 companies, 4120 orientation lectures and 1346 prevention workshops were given. Suspected skin lesions for skin cancer corresponded to 3.4% from 3054 skin assessment tests. 873 mammograms were performed, and 11 cases of suspected lesions were referred to the Pap smear, from 2073 collections. The SPA was altered in 8 men, in a total of 1308 tests performed. The installation of the mobile unit inside the company breaks two barriers preventing workers from carrying out their preventive exams: the sociocultural and the institutional. Thus, cancer screening programs and actions can contribute to the early diagnosis of this pathology, especially in the population of economically productive age.(AU)

ABSTRACT

Se presentó un paciente de sexo masculino de 71 años de edad que consultó por un cuadro compatible con abdomen agudo médico de comienzo brusco. Refirió antecedentes de diabetes mellitus tipo 2, obesidad, dislipemia e hipertensión arterial. Al examen físico se encontró: afebril, presión arterial (PA) 128/75 mmHg; a la palpación del abdomen se halló un abdomen globoso, blando, depresible, doloroso en ambas fosas iliacas, signo de Mc Burney negativo, sin signos de re-acción peritoneal, catarsis y diuresis conservadas. Se solicitó una tomografía computada (TC) abdominal con con-traste oral y endovenoso (EV). La TC informó, a nivel del sigma sobre el borde antimesentérico, una imagen nodular de densi-dad grasa con halo hiperintenso y alteración tomodensitometría de la grasa adyacente, además de imágenes diverticulares no complicadas. Con el cuadro clínico del paciente y los hallazgos tomográficos se arribó al diagnóstico de apendagitis epiploica. Se inició tratamiento conservador con abordaje nutricional.

ABSTRACT

RESUMEN Las infecciones del sitio quirúrgico constituyen un problema de calidad de los cuidados a la salud, las cuales son potencialmente prevenibles mediante la aplicación de guías de prevención basadas en evidencias. Se pretendedescribir la evolución histórica de las prácticas de uso profiláctico de antibióticos en cirugía de colon desde el siglo pasado. Se analizó literatura publicada en las últimas cinco décadas en MEDLINE, Infomed y otras fuentes secundarias. Se destaca la evolución del uso combinado de antimicrobianos (aminoglucósidos, penicilina, cefalosporinas y nitroimidazoles) asociados a la preparación enérgica del colon en la década de los 70 del pasado siglo. Numerosos antimicrobianos y prácticas han sido ensayados para demostrar que el uso de antibióticos para el control de las bacterias aerobias y anaerobias, administrados por vía oral e intravenosa, logra la prevención de hasta el 75 por ciento de las infecciones del sitio quirúrgico en cirugía de colon. Las evidencias científicas orientan hacia la necesidad del uso de profilaxis antibióticos orales más intravenosas asociados a la preparación mecánica del colon(AU)


ABSTRACT Surgical site infections are a concern with respect to quality of health care. Surgical site infections are potentially preventable through the application of evidence-based prevention guidelines. The aim is to describe the historical evolution of practicing prophylactic use of antibiotics in colon surgery since the last century. We analyzed the literature published in the last five decades in MEDLINE, Infomed and other secondary sources. The evolution is highlighted of the combined use of antimicrobials (aminoglycosides, penicillin, cephalosporins, and nitroimidazoles) associated with the vigorous preparation of the colon in the 1970s of the last century. Numerous antimicrobials and practices have been tested to demonstrate that the use of antibiotics to control aerobic and anaerobic bacteria, administered orally and intravenously, achieves the prevention of up to 75 percent of surgical site infections in colon surgery. Scientific evidence points to the need for the use of more intravenous oral antibiotic prophylaxis associated with mechanical preparation of the colon(AU)

ABSTRACT

PURPOSE: Hyperthermic intraperitoneal chemotherapy (HIPEC) is a novel treatment option for peritoneal surface malignancies. Due to cytotoxic effects of chemotherapeutic agents, anastomosis healing can be impaired and lead to leakage rates higher than conventional intestinal surgery. In this experimental study, we aimed to investigate the effects of platelet-rich plasma (PRP) on colonic anastomosis in rats that received HIPEC with oxaliplatin.METHODS: Thirty rats were divided into 3 groups. Group 1 was determined as control group and hyperthermic saline perfusion was performed after colon anastomosis. In group 2, colon anastomosis then hyperthermic oxaliplatin perfusion was performed. In the last group, the colonic anastomosis was enhanced by PRP gel and then hyperthermic oxaliplatin perfusion was performed. All the rats were reoperated on postoperative day 7 and anastomotic bursting pressure values were recorded. Tissue samples were taken for hydroxyproline assay and histopathological examination.RESULTS: Control group had higher anastomotic bursting pressure value than group 2 and group 3 (P < 0.001). There were significant differences in anastomotic bursting pressure between groups 2 and 3 (P < 0.001). Group 2 had significantly lower hydroxyproline levels than group 3 and control group (P < 0.001). Histopathological examination revealed that PRP application reduced inflammatory response.CONCLUSION: PRP application on colonic anastomosis improves anastomotic healing and can reduce anastomosis related complications and stoma creation; though further clinical studies are needed.

ABSTRACT

PURPOSE: As robotic surgery is increasingly performed in patients with colorectal diseases, understanding proper port placement for robotic colorectal surgery is necessary. This review summarizes current port placement during robotic surgery for colorectal diseases and provides future perspective on port placements.METHODS: PubMed were searched from January 2009 to December 2018 using a combination of the search terms “robotic” [MeSH], “colon” [MeSH], “rectum” [MeSH], “colorectal” [MeSH], and “colorectal surgery” [MeSH]. Studies related to port placement were identified and included in the current study if they used the da Vinci S, Si, or Xi robotic system and if they described port placement.RESULTS: This review included 77 studies including a total of 3,145 operations. Fifty studies described port placement for left-sided and mesorectal excision; 17, 3, and 7 studies assessed port placement for right-sided colectomy, rectopexy, transanal surgery, respectively; and one study assessed surgery with reduced port placement. Recent literatures show that the single-docking technique included mobilization of the second and third robotic arms for the different parts without movement of patient cart and similar to previous dual or triple-docking technique. Besides, use of the da Vinci Xi system allowed a more simplified port configuration.CONCLUSION: Robot-assisted colorectal surgery can be efficiently achieved with successful port placement without movement of patient cart dependent on the type of surgery and the robotic system.

ABSTRACT

BACKGROUND/AIMS: Ulcerative colitis (UC) is a type of inflammatory bowel disease that mainly involves the colon. Thus far, glucocorticoids and amino-salicylate have been the main treatment.METHODS: To assess drugs with fewer side effects, this study evaluated the effects of sodium cromoglycate (SCG) on acetic acid-induced UC in rats. The treatment groups included SCG receivers (50 and 100 mg/kg, intra-orally) and sulfasalazine (SSZ) receivers (100 mg/kg, intra-orally). The colonic mucosal injury was assessed by clinical, macroscopic, and histopathological examinations.RESULTS: In the treatment groups with 50 and 100 mg/kg of SCG, the clinical activity score decreased to 2.67±0.18 and 1.73±0.21 (p<0.05), respectively, compared to the UC control group (3.21±0.31), and were higher than that of the group given the standard treatment of 100 mg/kg SSZ (1.10±0.09). The treatment groups with 50 and 100 mg/kg of SCG showed a lower clinical gross lesion score than the UC control group (2.91±0.28 and 2.10±0.43, vs. 4.49±0.61, p<0.05) and were higher than the standard group (0.95±0.18). Treatment with SCG (100 mg/kg) decreased the macroscopic scores significantly compared to the UC control group (p<0.05) on the 8th day.CONCLUSIONS: SCG (100mg/kg) decreased significantly the clinical activity score, gross lesion, and percentage-affected area compared to the UC controls on the 8th day.

ABSTRACT

Intussusception is a medical condition, in which a proximal part of the intestine folds into the distal intestine. Adult intussusceptions are rare and account for approximately 5% of all cases of intussusceptions. The anatomical leading points include tumors, diverticulums, polyps, and strictures in 80-90% of adult intussusceptions, and 65% of colon intussusceptions and 30% of small bowel intussusceptions originate from malignant tumors. Treatments for adult intussusception have not been established, but most cases require surgical treatment. The gastrointestinal tract is the most common extranodal site for non-Hodgkin lymphoma. The symptoms are mostly non-specific, but they rarely lead to complications, such as bleeding, perforation, and intussusception. Furthermore, few cases of primary gastrointestinal lymphomas causing intussusception have been reported. This paper reports a case of small bowel diffuse large B cell lymphoma that caused ileocolic intussusception in a 69-year-old woman with no medical history. She underwent a small bowel resection and received six cycles of adjuvant chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone. Since then, she has been in complete remission.
