ABSTRACT Background Non specific colitis is defined as inflammatory condition of the colon that when examined microscopically lacks any characteristic features of any specific form of colitis and is commonly seen in reports of colonoscopy biopsies. There are many factors that cause it like obesity and H pylori. Aim of the study To determine the association of obesity and H pylori as contributory factors to this disease. Patients and methods This is a case-controlled study was carried out in Al-Kindy College of Medicine from January 2017 to June 2018. Sixty individuals were included; forty of them had non specific colitis. The rest were healthy control group. Demographic information's were taken like age and sex. Anthropometric measurement like weight in kilograms (kg), height in meters (m), waist circumference in centimeters (cm), and body mass index was done. H pylori IgG was done to both groups. Results Study results indicated that this disease was more common with increasing age, there is a significant difference (p = 0.002) between patients (48.12 ± 1.50) and control group (41.00 ± 1.10) regarding age. BMI of the patients is significantly higher in patients group (29.21 ± 0.41; p = 0.000) than the control (22.23 ± 0.41). Patients with non specific colitis showed significant (p = 0.000) increased in H pylori infection 33 (82.5%) compared with control group 2 (10%). Conclusions Obesity and infection withH pylori may predispose to non specific colitis.

RESUMO Introdução Colite inespecífica é uma condição inflamatória do cólon que microscopicamente não apresenta características de qualquer forma específica de colite; é comumente observada em relatórios patológicos de biópsias de colonoscopia. Vários fatores podem causar colite inespecífica, dentre os quais obesidade e infecção por H. pylori. Objetivo do estudo Determinar o possível papel da obesidade e H. pylori como fatores contribuintes para esta doença. Pacientes e Métodos Este foi um estudo caso-controle, realizado na Al-Kindy College of Medicine entre janeiro de 2017 e junho de 2018. Um total de 60 indivíduos foram incluídos, 40 dos quais apresentavam colite inespecífica. Os demais foram incluídos no grupo de controles saudáveis. Foram coletadas informações demográficas, como idade e sexo. Medidas antropométricas, como peso (kg), altura (m), circunferência da cintura (cm) e índice de massa corporal, também foram coletadas. Nos dois grupos, foi feita serologia para H. pylori (IgG) Resultados Os presentes resultados indicaram que esta doença era mais comum entre pacientes de idade mais avançada; observou-se uma diferença significativa p = 0,002 entre os pacientes 48,12 ± 1,50 e o grupo controle 41,00 ± 1,10 quanto à idade. O IMC foi significativamente maior no grupo de pacientes 29,21 ± 0,41; p = 0,000 do que no grupo controle 22,23 ± 0,41. A infecção por H. pylori foi significamente mais frequentemente observada no grupo de pacientes (33; 82,5%) em comparação ao grupo controle (2; 10%; p = 0,000. Conclusões A obesidade e a infecção por H. pylori podem predispor à colite inespecífica.

ABSTRACT Chagasic megacolon is the second most frequent cause of manifestation of the digestive forms of Chagas disease (trypanosoma cruzi parasitosis), characterized by progressive pseudo-occlusive symptoms or chronic constipation, caused by an alteration in the functioning of the colonic wall musculature. In Venezuela, cases of chagasic disease reported in the past are referred to chagasic heart disease, this being the first documented case of chagasic megacolon. We broach herein a case of chagasic megacolon in which early diagnosis and prompt surgical treatment led to a successful outcome.

RESUMO O megacólon chagásico é a segunda causa mais frequente de manifestação das formas digestivas da doença de Chagas (parasitose do Trypanosoma cruzi), caracterizado por sintomas pseudo-oclusivos progressivos ou constipação crônica, causado por uma alteração no funcionamento da musculatura da parede do cólon. Na Venezuela, os casos da doença chagásica relatados no passado são referidos como doença cardíaca chagásica, sendo este o primeiro caso documentado de megacólon chagásico. Neste artigo, abordamos um caso de megacólon chagásico no qual o diagnóstico precoce e o tratamento cirúrgico imediato levaram a um resultado bem-sucedido.

OBJECTIVE: Stoma prolapse is an intussusception of the bowel through a mature stoma. It can be caused by increased intra-abdominal pressure, excessively mobile bowel mesentery and/or a large opening in the abdominal wall at the time of stoma formation. It occurs predominantly in loop stomas, and correction methods include conservative modalities, such as local reduction to the prolapsed bowel, or surgical treatment. The purpose of this study was to describe our experience with the treatment of colostomy prolapse using a novel mesh strip technique. METHODS: Between February 2009 and March 2018, ten consecutive male patients underwent correction of colostomy prolapse under local anesthesia by peristomal placement of a polypropylene mesh strip. Operation time, short- and long-term complications, and recurrence rates were recorded and analyzed. RESULTS: No postoperative complications, morbidity or mortality were observed. The median length of the prolapse ranged from 6-20 cm, and the median operative time was 30 minutes. The median duration of follow-up was 25 months (range, 12-89 months). No relapse, mesh strip extrusion, local infection or granuloma formation were found. CONCLUSION: A simple, fast, and low-cost operation under local anesthesia using a mesh strip is a valuable option to treat colostomy prolapse.

ABSTRACT Background: Intestinal diversions have revolutionized the treatment of morbid obesity due to its viability and sustained response. However, experimental studies suggest, after these derivations, a higher risk of colon cancer. Aim: To analyze the histological and immunohistological changes that the jejunojejunal shunt can produce in the jejunum, ileum and ascending colon. Method: Twenty-four male Wistar rats were randomly divided into two groups, control (n=12) and experiment (n=12) and subdivided into groups of four. Nine weeks after the jejunojejunal shunt, segmental resection of the excluded jejunum, terminal ileum and ascending colon was performed. Histological analysis focused on the thickness of the mucosa, height of the villi, depth of the crypts and immunohistochemistry in the expression of Ki-67 and p53. Results: Significant differences were found between the experiment and control groups in relation to the thickness of the mucosa in the jejunum (p=0.011), in the ileum (p<0.001) and in the colon (p=0.027). There was also a significant difference in relation to the height of the villus in the ileum (p<0.001) and the depth of the crypts in the jejunum (p0.001). The results indicated that there is a significant difference between the groups regarding the expression of Ki-67 in the colon (p<0.001). No significant differences were found between the groups regarding the expression of Ki-67 in the jejunum and ileum. In the P53 evaluation, negative nuclear staining was found in all cases. Conclusion: The jejunojejunal deviation performed in the Roux-in-Y gastrojejunal bypass, predispose epithelial proliferative effects, causing an increase in the thickness of the mucosa, height of the villi and depth of the crypts of the jejunum, ileum and ascending colon.

RESUMO Racional: As derivações intestinais revolucionaram o tratamento da obesidade mórbida pela sua viabilidade e resposta sustentada. Porém, estudos experimentais sugerem, após estas derivações, risco maior de câncer de cólon. Objetivo: Analisar as alterações histológicas e imunoistológicas que a derivação jejunojejunal possa produzir no jejuno, íleo e cólon ascendente. Método: Foram utilizados 24 ratos Wistar machos randomicamente divididos em dois grupos, controle (n=12) e experimento (n=12) e subdivididos em grupos de quatro. Nove semanas após a derivação jejunojejunal procedeu-se a ressecção segmentar do jejuno excluso, íleo terminal e cólon ascendente. Análise histológica focou na espessura da mucosa, altura dos vilos, profundidade das criptas e a imunoistoquímica na expressão do Ki-67 e p53. Resultados: Foram encontradas diferenças significativas entre os grupos experimento e controle em relação à espessura da mucosa no jejuno (p=0,011), no íleo (p<0,001) e no cólon (p=0,027). Também houve diferença significativa em relação à altura dos vilos no íleo (p<0,001) e profundidade das criptas no jejuno (p<0,001). Os resultados indicaram que existe diferença significativa entre os grupos em relação à expressão do Ki-67 no cólon (p<0,001). Não foram encontradas diferenças significativas entre os grupos em relação à expressão do Ki-67 no jejuno e no íleo. Na avaliação do P53, foi encontrada coloração nuclear negativa em todos os casos. Conclusão: O desvio realizado na derivação gastrojejunal em Y-de-Roux, predispõem efeitos proliferativos epiteliais, causando aumento da espessura da mucosa, altura dos vilos e profundidade das criptas do jejuno, íleo e cólon ascendente.

Introducción. Los protocolos de recuperación mejorada después de cirugía se han diseñado como una innovación en salud tras demostrarse que la mejora en los dispositivos médicos y la depuración de técnicas alcanzaron la meseta en disminución de complicaciones. Con estas estrategias de la medicina perioperatoria, en cirugía colorrectal se reducen la morbilidad y estancia hospitalaria. El objetivo del estudio fue evaluar si la tasa de adherencia al programa de recuperación mejorada después de la cirugía (ERAS) está asociada con los resultados quirúrgicos. Métodos. Estudio multicéntrico, observacional, retrospectivo de cohorte (2015-2019), en cinco hospitales latinoamericanos certificados por la sociedad ERAS. Se calculó la incidencia de complicaciones quirúrgicas durante el posquirúrgico inmediato (30 días) y la duración de la estancia hospitalaria. Se utilizaron análisis bivariado y regresión logística multivariada para evaluar los factores asociados con la tasa de complicaciones. Resultados. Fueron incluidos en el estudio 648 pacientes en cinco hospitales ERAS, con edad promedio de 61 años y mayor porcentaje de hombres (51 %). El cumplimiento global al protocolo ERAS fue de 75 % y la estancia promedio de 6,2 días (mediana: 4 días). Se tuvo un cumplimiento óptimo del protocolo ERAS (igual o mayor al 80 %) en 23,6 % de los pacientes. Se documentó fuga de la anastomosis en 4 %, complicaciones infecciosas en 8,4 %, íleo en 5,7 %, reingreso en 10,2 % y mortalidad de 1,1 %. El análisis multivariado mostró que los niveles de adherencia óptima al protocolo ERAS reducen significativamente la aparición de complicaciones como fuga de la anastomosis (OR 0,08; IC95% 0,01-0,48; p=0,005) y complicaciones infecciosas (OR 0,17; IC95%0,03-0,76; p=0,046).Discusión. Los resultados sugieren que un cumplimiento del programa ERAS mayor al 80 % se asocia a menor frecuencia de complicaciones en pacientes con cirugía electiva colorrectal

Introduction. Enhanced Recovery After Surgery (ERAS) protocol has been designed as an innovation in health after demonstrating that the improvement in medical devices and the refinement of techniques reached the plateau in reducing complications. With these strategies of perioperative medicine, in colorectal surgery morbidity and hospital stay are reduced. The aim of the study was to evaluate whether the rate of adherence to the ERAS protocol is associated with surgical outcomes.Methods. Multicenter, observational, retrospective cohort study (2015-2019), in five Latin American hospitals certified by the ERAS Society. The incidence of surgical complications during the immediate postoperative period (30 days) and length of hospital stay were calculated. Bivariate analyzes and multivariate logistic regression were used to assess factors associated with complication rates.Results. 648 patients were included in the study in five ERAS hospitals, with an average age of 61 years and a higher percentage of men (51%). Overall compliance with the ERAS protocol was 75% and the average stay was 6.2 days (median: 4 days). There was optimal compliance with the ERAS protocol (equal to or greater than 80%) in 23.6% of the patients. Anastomotic leak was documented in 4%, infectious complications in 8.4%, ileus in 5.7%, readmission in 10.2%, and mortality in 1.1%. Multivariate analysis showed that optimal adherence levels to the ERAS protocol significantly reduce the appearance of complications such as anastomotic leakage (OR 0.08; 95%CI 0.01-0.48; p=0.005) and infectious complications (OR 0.17; 95%CI 0.03-0.76; p=0.046).Discussion. The results suggest that compliance with the ERAS program greater than 80% is associated with a lower frequency of complications in patients with elective colorectal surgery

Introducción. El cáncer de colon es una de las principales causas de morbimortalidad a nivel mundial. En Colombia se presentan cerca de 145,600 casos nuevos al año. Cada vez son más los reportes de este tipo de patologías intervenidas por vía laparoscópica, aunque son pocos en Colombia. El objetivo de este artículo es mostrar el abordaje de esta patología mediante un procedimiento mínimamente invasivo: la colectomía derecha por vía laparoscópica, el cual es poco utilizado en el país. Caso clínico. Paciente de 86 años que consulta por pérdida de peso, adinamia y dolor abdominal en flanco derecho. Presenta además anemia ferropénica y sangre oculta en materia fecal. Las endoscopias digestivas muestran lesión ulcerada vegetante de aspecto neoplásico a nivel del ciego. La biopsia revela adenocarcinoma infiltrante moderadamente diferenciado con áreas de necrosis. Se realiza una colectomía derecha por técnica laparoscópica. Se hace seguimiento con neoadyuvancia por parte de Oncología Clínica. Discusión. El adenocarcinoma es uno de los cánceres primarios más comunes en el colon. La resección quirúrgica es una excelente alternativa para el manejo y tratamiento de estos tumores. En Colombia, la mayoría de estas resecciones se realizan por vía abierta. La resección por vía laparoscópica es un método que demuestra similar eficacia, ofreciendo una disminución en la respuesta inflamatoria, con mejor control del dolor y limitaciones funcionales. Conclusiones. La colectomía por vía laparoscópica para resección de tumores de colon es un método seguro, eficaz y reproducible. Sin embargo, exige tecnología de alto costo y debe ser realizada por un grupo quirúrgico con habilidad y experiencia en sutura manual laparoscópica.

Introduction. Colon cancer is one of the main causes of morbimortality in the world. Colombia counts near 145,600 new cases per year. The reports of laparoscopic intervention in this pathology are growing, but in Colombia there is little recent work on the matter. The aim of this article is to show how this pathology can be addressed through a minimally invasive procedure, laparoscopic right colectomy, which is not frequently used in the country. Clinical case. An 86-year-old patient consults due to weight loss, adynamia and abdominal pain on right side. Iron-deficiency anemia and hidden blood in feces was reported. The digestive endoscopies show the presence of a vegetant and ulcerated lesion of neoplastic appearance in the cecum. A biopsy revealed a moderately differentiated, invasive adenocarcinoma with areas of necrosis. A laparoscopic right colectomy is conducted. Definitive report of moderately differentiated and ulcerated, invasive, mucinous adenocarcinoma, with lesion up to the serous membrane. Follow up is conducted with neoadjuvant therapy by the Clinical Oncology service. Discussion. Adenocarcinoma is one of the most common primary cancers in the colon. Surgical still an excellent alternative for the management of this kind of tumor. In Colombia, the majority of these resections are carried out by open surgery. However, laparoscopic resection is a method that offers similar outcomes to the traditional procedure, while providing a reduction in the inflammatory response, with better pain control and control of functional limitations. Conclusions. Laparoscopic colectomy for the resection of colonic tumors is a safe, effective and reproducible method. However, it requires high-cost technology and it must be conducted by a surgical team skilled and experienced in manual laparoscopic suturing.Cómo citar: López-Gómez LE, Dominguez ­ Alvarado GA, D ́vera Camargo D, Lozano-Eslava LA, Martínez-Rojas PA.

Introdução. O câncer de cólon é uma das principais causas de morbimortalidade em todo o mundo. Na Colômbia, há uma incidência aproximada de 145,600 casos novos por ano. Na Colômbia existam poucos trabalhos recentes sobre este tipo de procedimentos. O objetivo deste artigo é mostrar a abordagem de o adenocarcinoma de cólon, através de um procedimento minimamente invasivo: a colectomia direita pela via laparoscópica, pouco utilizada no país. Caso clínico. Paciente de 86 anos que apresenta perda de peso, adinamia e dor abdominal no flanco direito, anemia ferropriva e sangue oculto nas fezes. As endoscopias digestivas evidenciam a presença de uma lesão ulcerada vegetante com aparência neoplásica no nível do ceco. A biópsia revelou adenocarcinoma infiltrante moderadamente diferenciado com áreas de necrose. As imagens de extensão mostram um efeito de massa intraluminal ao nível do ceco com adenomegalia pericecal. Realizou-se uma colectomia direita laparoscópica. Relato definitivo de adenocarcinoma mucinoso infiltrante moderadamente diferenciado e ulcerado, com comprometimento da serosa. O serviço de Oncologia Clínica fez o acompanhamento neoadjuvante. Discussão. O adenocarcinoma é um dos cânceres primários mais comuns no cólon. A ressecção cirúrgica continua sendo uma excelente alternativa para a gestão e tratamento deste tipo de tumores. Na Colômbia, a maioria dessas ressecções é realizada pela via aberta. A ressecção pela via laparoscópica é um método que oferece ressecções semelhantes às do procedimento tradicional, apresentando diminuição da resposta inflamatória, com melhor controle da dor e das limitações funcionais. Conclusão. A colectomia pela via laparoscópica para ressecção de tumores de cólon é um método seguro, eficaz e reprodutível. No entanto, requer tecnologia de alto custo e deve ser realizada por um grupo cirúrgico com habilidade e experiência em sutura manual laparoscópica.

INTRODUCCIÓN: La enfermedad diverticular de colon sigmoides representa la principal causa de fistulización del colon a órganos vecinos. OBJETIVO: Describir variables clínicas y terapia quirúrgica de esta entidad. MATERIALES Y MÉTODO: Revisión retrospectiva de los casos de fístulas colónicas de origen diverticular (FCD) operados en forma electiva en un centro terciario. RESULTADOS: En un periodo de 30 años se realizó cirugía resectiva por una FCD en 49 pacientes. Los órganos más afectados fueron la vejiga en 33 casos (68%) y la vagina en 6 (12%). La cirugía efectuada fue la sigmoidectomía en 48 casos (5 con una ileostomía de protección) y una operación de Hartmann. La vía de abordaje fue laparoscópica en 4 pacientes y la morbilidad global de la serie fue 20%, sin mortalidad. Con un seguimiento promedio de 87 meses (extremos 16-178) no hubo casos de recidiva de la fístula. CONCLUSIONES: La FCD representa el 26% de los casos intervenidos por una enfermedad diverticular de colon sigmoides, lo que probablemente refleja un diagnóstico tardío. La fístula colovesical (FCV) es la fístula más común por esta causa y en la mitad de los casos tienen una presentación silenciosa. Las fístulas colovaginales ocurren en mujeres histerectomizadas. La cirugía resectiva del colon en pacientes con riesgo normal es la cirugía estándar con buenos resultados a corto y largo plazo. La cirugía laparoscópica es factible y segura especialmente en los casos de FCV.

BACKGROUND: Fistula formation is a well-known complication of diverticular disease (FCD). AIM: Determine the clinical presentation and surgical management of this kind of fistulas. MATERIALS AND METHODS: Retrospective revision of all consecutive scheduled cases operated on in a terciary public centre in a thirty-years period. RESULTS: Forty-nine patients with a segmental resection of sigmoid colon were analized. Colovesical fistulas were the most common type (n = 33), followed by colovaginal (n = 6). Resection with anastomosis was performed in 48 cases and Hartmann type operation in one. Laparoscopic procedure was made in 4 cases without conversion. Complication rate was 20% and two patients were reoperated on, without mortality in this series. Follow up showed no case of recurrence. CONCLUSIONS: FDC represent 26% of cases operated on in our series. Colovesical fistula is the most common type, followed by colovaginal fistula in histerectomized women. Resection and primary anastomosis should be the treatment of choice in average risk patients with acceptable morbidity and good long-term results. Laparoscopic approach is safe, specifically in patients with colovesical fistulas.

INTRODUCCIÓN: En la endometriosis el compromiso intestinal afecta hasta al 12% de las pacientes, comprometiendo al recto y a la unión rectosigmoidea en el 90% de los casos. OBJETIVO: Describir la experiencia del equipo de Coloproctología y Ginecología de Clínica Alemana de Santiago en el tratamiento quirúrgico de la endometriosis pélvica profunda con compromiso colorrectal. MATERIAL Y MÉTODOS: Estudio retrospectivo a partir de la base de datos de pacientes con endometriosis tratados entre enero del año 2015 y abril de 2018. Los criterios de inclusión fueron pacientes con clínica de endometriosis pélvica profunda, que tuviesen compromiso colorrectal y hayan sido tratados con shaving rectal, resección discoide o resección segmentaria. Se revisaron fichas clínicas electrónicas, protocolos operatorios y biopsias definitivas. RESULTADOS: Se reclutaron 25 pacientes con una mediana de edad de 35 años. El síntoma principal de consulta fue dismenorrea y el síntoma digestivo más frecuente fue disquecia. En 8 pacientes se realizó un shaving rectal, en 7 una sigmoidectomía, en 9 una resección discoide y en 1 paciente una tiflectomía. La complicación posoperatoria reportada fue la hemorragia digestiva baja en 4 pacientes (Clavien-Dindo I y IIIa). Con una mediana de seguimiento de 13 meses, a la fecha 3 pacientes se les ha diagnosticado algún tipo de recidiva. CONCLUSIÓN: Es importante que la cirugía a realizar, garantice una morbilidad y recurrencia baja. Los resultados en nuestro centro son alentadores, lo que nos hace creer que el tratamiento quirúrgico podría ser una buena alternativa en la endometriosis pélvica profunda con compromiso colorrectal.

INTRODUCTION: In endometriosis, intestinal involvement affects up to 12% of patients, compromising the rectum and the rectosigmoid junction in 90% of cases. AIM: Describe the experience of the Coloproctolgy and Gynecology Team of the Clínica Alemana de Santiago in the surgical treatment of deep pelvic endometriosis with colorectal involvement. MATERIAL AND METHODS: Retrospective study based on the database of patients with endometriosis treated between January 2015 and April 2018. The inclusion criteria were patients with deep pelvic endometriosis clinic, who had colorectal involvement and who had been treated with rectal shaving, discoid resection or segmental resection. Electronic clinical records, operative protocols and definitive biopsies were reviewed. RESULTS: Twenty-five patients with a median age of 35 years were recruited. The main symptom of consultation was dysmenorrhoea and the most frequent digestive symptom was dyschezia. In 8 patients a rectal shaving was performed, in 7 a sigmoidectomy, in 9 a discoid resection and in 1 patient a tiflectomy. The only reported post-operative complication was low gastrointestinal bleeding in 4 of the 25 patients (Clavien-Dindo I and IIIa). A median follow-up of 13 months was achieved, to date 3 patients have been diagnosed with some type of recurrence. CONCLUSION: It is important that the surgery to be performed guarantees low morbidity and recurrence. The results in our center are encouraging, which makes us believe that surgical treatment could be a good alternative in deep pelvic endometriosis with colorectal involvement.

ABSTRACT BACKGROUND: Despite advances in surgical approaches, emergency colorectal surgery has high mortality and morbidity. OBJECTIVE: We aimed to create a simple and distinctive scoring system, for predicting mortality among patients undergoing emergency colorectal surgery. DESIGN AND SETTING: Prediction model development study based on retrospective data-gathering. METHODS: Patients who underwent emergency colorectal surgery between March 2014 and December 2016 at a single tertiary-level referral center were included in our study. Patient demographics, comorbidities, type of surgery, etiology and laboratory and radiological findings were collected retrospectively and analyzed. A new clinical score (named the Numune emergency colorectal resection score) was constructed from the last logistic regression model, in which one point was assigned for the presence of each predictive factor. RESULTS: 138 patients underwent emergency colorectal surgery. These comprised 64 males (46.4%) and 74 females (53.6%), with a mean age of 64 years. Multivariate analysis revealed that blood urea nitrogen level > 65 mg/dl (odds ratio, OR: 8.03; 95% confidence interval, CI: 2.16-15.77), albumin level < 0.7 ­mg/­dl (OR: 4.43; 95% CI: 1.96-14.39) and American Society of Anesthesiologists score ≥ 3 (OR: 3.47; 95% CI: 0.81-9.18) were associated with postoperative complications. The Numune score was graded from I to III. The risk of mortality was found to be 63.2% in the group with grade III, which accounted for 35.2% of the subjects. There were 37 postoperative deaths. CONCLUSIONS: Surgeons need scoring systems, especially to predict postoperative mortality. We propose the Numune emergency colorectal resection score for emergency surgical procedures as a practical, usable and effective system for predicting postoperative morbidity.

ABSTRACT Introduction: Colorectal carcinoma is commonest cancer of gastrointestinal tract. It is represent third cancer in man worldwide beyond lung and prostate cancers. It is fourth cancer in woman beyond breast, lung and uterus cancers. Deaths from colorectal cancer are more in compare with other GIT cancers. Objective: The aim is prove epidemiological and clinical data of colorectal cancer. Method: Our study conducted in Misan Province, Iraq. The data collected from 2013 to 2016. Seventy one patients that found have colorectal cancer. Gender, age, residency, site of cancer, family history, past history, year of onset, smoking history, alcohol intake, presentation, staging and histopathology pattern are get.

RESUMO Introdução: O carcinoma colorretal é o câncer mais comum do trato gastrointestinal. É o terceiro tipo de câncer mais observado no sexo masculino mundialmente, atrás dos cânceres de pulmão e próstata. É o quarto câncer mais observado no sexo feminino, atrás dos cânceres de mama, pulmão e útero. As mortes por câncer colorretal são mais comuns comparadas a outros cânceres do TGI. Objetivo: O objetivo do estudo é comprovar dados epidemiológicos e clínicos do câncer colorretal. Métodos: Nosso estudo foi conduzido na província de Misan, no Iraque. Os dados foram coletados de 2013 a 2016. Setenta e um pacientes apresentaram câncer colorretal. Sexo, idade, local de residência, local do câncer, história familiar, história pregressa, ano de início, história de tabagismo, etilismo, apresentação, estadiamento e padrão histopatológico foram obtidos. Resultados: A prevalência de carcinoma de cólon e reto é de 3,75%. A faixa etária mais afetada foi de 51 a 60 anos, com 30,99%. O gênero e o local de residência dos pacientes não afetam a porcentagem de ocorrência do câncer. Obesidade, antecedentes familiares, tabagismo e consumo de álcool são fatores de risco. 42,25% dos pacientes tinha história familiar de câncer. Conclusão: O local mais comum de carcinoma colorretal é o cólon esquerdo, com 61,97%. Houve aumento na detecção de novos casos de carcinoma colorretal de 2013 a 2016. Os estágios avançados de câncer mais comuns foram IIIA, IIIB, IIIC e IV em 12,67%, 16,90%, 19,72% e 15,49% dos casos. O padrão histopatológico comum é o adenocarcinoma diferenciado, em 53,52% dos casos.

ABSTRACT Objective: Ulcerative colitis usually affects the rectum and potentially can involve the whole colon. Noninvasive methods such as fecal calprotectin measurement may be considered as a reliable and inexpensive approach in assessing disease severity or treatment change strategy. Methods: In this retrospective cross-sectional study, records of 56 ulcerative colitis patients who hospitalized with exacerbation between May 2016 and April 2017 were assessed based on IBD Data Bank Software in Gastrointestinal and Liver Diseases and Research Center (GLDRC), Guilan province, Iran between. A questionnaire of demographic characteristics, clinical findings and fecal calprotectin level was completed. Montreal classification severity of ulcerative colitis and Mayo disease activity index were scored. Data were analyzed for descriptive and analytical analysis. Results: Fecal calprotectin was significantly different in terms of disease severity based on both Mayo score (p = 0.007) and Montreal classification (p = 0.001). In patients with mild symptoms, no increase in fecal calprotectin was observed, but in patients with moderate and severe elevations in fecal calprotectin levels was significant. Also, C-Reactive Protein surge was related to disease severity (p = 0.02). Furthermore, regression comparison among high-chance patients based on fecal calprotectin was significantly related to higher Erythrocyte Sedimentation Rate levels and smoking, p = 0.01 and p = 0.05, respectively. Conclusion: It seems fecal calprotectin levels are related to the disease severity. Non-invasive methods, such as fecal calprotectin assay, may seem to be an alternative to aggressive, costly and time-consuming methods, such as colonoscopy and biopsy, to reduce the suffering of patients and ultimately help improve the patients' life quality.

RESUMO Objetivo: A colite ulcerativa geralmente afeta o reto, podendo acometer todo o cólon. Métodos não invasivos, como a dosagem de calprotectina fecal, podem ser uma abordagem confiável e barata para a avaliação da gravidade da doença ou da estratégia de mudança de tratamento. Métodos: Neste estudo transversal retrospectivo, os registros de 56 pacientes com colite ulcerativa que foram hospitalizados devido a exacerbação entre maio de 2016 e abril de 2017 foram avaliados usando o software IBD Data Bank no Centro de Pesquisa e Doenças Gastrointestinais e Hepáticas (GLDRC), na província de Guilan, Irã. Foi aplicado um questionário de características demográficas, achados clínicos e nível de calprotectina fecal. Foram usados o escore de Mayo de atividade da doença e a classificação de Montreal da gravidade da colite ulcerativa. Os dados foram analisados de forma descritiva e analítica. Resultados: A calprotectina fecal apresentou diferença significativa em termos de gravidade da doença com base no escore de Mayo (p = 0,007) e na classificação de Montreal (p = 0,001). Em pacientes com sintomas leves, nenhum aumento na calprotectina fecal foi observado. Entretanto, em pacientes com sintomas moderados e severos, o aumento nos níveis de calprotectina fecal foi significativo. Além disso, o aumento nos níveis de proteína C reativa foi associado à gravidade da doença (p = 0,02). A análise da regressão entre pacientes considerados de alto risco com base na calprotectina fecal indicou uma associação significativa com níveis elevados da taxa de sedimentação de eritrócitos e tabagismo (p = 0,01 e p = 0,05, respectivamente). Conclusão: Os níveis de calprotectina fecal parecem estar relacionados com a gravidade da doença. Métodos não invasivos, como o estudo de calprotectina fecal, podem ser uma alternativa a métodos agressivos, caros e demorados, tais como colonoscopia e biópsia, reduzindo o sofrimento e ajudando a melhorar a qualidade de vida dos pacientes.

ABSTRACT Globally, colorectal cancer is the third leading cause of cancer death among men and the second among women, corresponding to about 10% of all cancers. The Brazilian Ministry of Health and National Cancer Institute recommend the screening of colorectal cancer for people over 50 years-old with Fecal Occult Blood Test. Endoscopy is limited to patients with positive screening results. The aim of this study is to evaluate the incidence of malignant or premalignant lesions diagnosed by endoscopy in patients with positive or negative Fecal Occult Blood Test and assess the efficacy of Fecal Occult Blood Test to predict the finding of a malignant colorectal lesion. We carried out a cross-sectional study among patients with a Fecal Occult Blood Test result that were submitted to colonoscopy, in the same hospital, from March 2016 to July 2017. Sensitivity, specificity, positive and negative predictive value of Fecal Occult Blood Test compared to colonoscopy neoplastic findings was calculated. The total of 92 patients were enrolled, 52 (56.5%) were female, Fecal Occult Blood Test was positive in 42.4% of them and in 41 (44.6%) the colonoscopy showed abnormal findings. Polyps were the most frequent alteration, found in 20 patients (21.7%). Among the patients with polyps, 15 (16.3%) had neoplastic and 5 (5.4%) presented non-neoplastic polyps. The Fecal Occult Blood Test sensitivity for detection of neoplastic polyps was 66.7%, specificity 62.3%, positive predictive value 11% and negative predictive value was 94.2%. Considering the need for a screening method, Fecal Occult Blood Test showed to be an effective and reliable screening test that can be applied in public health programs to detect and prevent colorectal cancer.

RESUMO Globalmente, o carcinoma colorretal é a terceira principal causa de morte por neoplasia entre homens e a segunda entre mulheres, correspondendo a 10% de todas as neoplasias. O Ministério da Saúde Brasileiro e o Instituto Nacional do Câncer recomendam a triagem do câncer colorretal para indivíduos acima de 50 anos, utilizando a Pesquisa de Sangue Oculto nas fezes. A endoscopia é reservada para aqueles com Pesquisa de Sangue Oculto nas fezes positiva. O objetivo deste estudo é avaliar a incidência de lesões malignas/pré-malignas diagnósticas na colonoscopia e correlacionar com os resultados prévios da Pesquisa de Sangue Oculto e verificar a eficácia da Pesquisa de Sangue Oculto para predizer uma lesão colorretal maligna. Realizamos um estudo transversal em pacientes que apresentavam resultados positivos ou negativos de Pesquisa de Sangue Oculto nas fezes e foram submetidos à colonoscopia, na mesma instituição, entre março de 2016 e julho de 2017. Dos 92 participantes; 52 (56,5%) eram do sexo feminino, a Pesquisa de Sangue Oculto nas fezes foi positiva em 42,4%; e em 41 (44,6%) a colonoscopia mostrou alterações. Em 20 pacientes (21,7%) havia pólipos; 15 (16,3%) eram neoplásicos e 5 (5,4%) não neoplásicos. A sensibilidade da Pesquisa de Sangue Oculto nas fezes para detecção de pólipos neoplásicos foi 66,7%; a especificidade 62,3%; o valor preditivo positivo 11% e o valor preditivo negativo 94,2%. Considerando a necessidade de um método de triagem, a Pesquisa de Sangue Oculto nas fezes mostrou ser um exame de triagem eficaz e confiável para ser aplicado em programas de saúde pública com o objetivo de detectar e prevenir o carcinoma colorretal.

ABSTRACT Background: Chagasic colopathy is the second most common digestive manifestation, and constipation is the main symptom. The absence of the Rectoanal Inhibitory Reflex plays an important role in constipation and anal manometry is crucial for appropriate evaluation. Purpose: Evaluate anal manometry findings (mainly Rectoanal Inhibitory Reflex) in Chagasic patients with chronic constipation, with and without megacolon and correlate these findings with clinical and demographic data. Methods: Cross-sectional study of patients with chronic constipation who underwent Chagasic serologic test, barium enema, and anal manometry. The absence of Rectoanal Inhibitory Reflex was evaluated using the mid-P Exact Test. Results: 64 Patients were included: 23 Chagasic patients with megacolon/megarectum (G1), 21 Chagasic patients without megacolon/megarectum (G2) and 20 non-Chagasic patients without megacolon/megarectum (G3). Chagasic patients with megacolon had a higher incidence of fecaloma (39%) compared to the other two groups (9.5% and 10% for G2 and G3, respectively, p = 0.03). Rectal capacity on manometry was statically higher for G1 patients. Rectoanal Inhibitory Reflex was absent in 91.3% of patients in G1, 47.29% in G2 and present in all patients in G3. There was a significant difference in the absence of the Rectoanal Inhibitory Reflex when comparing the groups (G1 vs. G2: p = 0.002, G1 vs. G3: p < 0.001, G2 vs. G3: p < 0.001). Conclusion: The absence of RAIR confirms the diagnosis of Chagasic colopathy and endorses surgical treatment whenever clinical treatment fails. The presence of the RAIR in patients with positive serology for Chagas disease without megacolon/megarectum might not be due chagasic colopathy and other causes should be considered.

RESUMO Fundamento: A colopatia chagásica é a segunda manifestação digestiva mais comum e a constipação é o principal sintoma. A ausência do Reflexo Inibitório Retoanal desempenha um papel importante na constipação e a manometria anal é crucial para avaliação adequada. Objetivo: Avaliar os achados da manometria anal (principalmente o Reflexo Inibitório Retoanal) em pacientes chagásicos com constipação crônica, com e sem megacólon, e correlacionar esses achados com dados clínicos e demográficos.Métodos: Estudo transversal de pacientes com constipação crônica submetidos ao teste sorológico para doença de chagas, enema de bário e manometria anal. A ausência de Reflexo Inibitório Retoanal foi avaliada por meio do Teste Exato de Ponto Médio. Resultados: Foram incluídos 64 pacientes: 23 chagásicos com megacólon/megarreto (G1), 21 chagásicos sem megacólon/megarreto (G2) e 20 não chagásicos sem megacólon/megarreto (G3). Os pacientes chagásicos com megacólon apresentaram maior incidência de fecaloma (39%) em comparação aos outros dois grupos (9,5% e 10% para G2 e G3, respectivamente, p = 0,03). A capacidade retal na manometria foi estatisticamente maior nos pacientes do G1. O Reflexo Inibitório Retoanal estava ausente em 91,3% dos pacientes do G1, em 47,29% no G2 e presente em todos os pacientes do G3. Houve diferença significativa na ausência do Reflexo Inibitório Retoanal quando comparados os grupos (G1 vs. G2: p = 0,002, G1 vs. G3: p < 0,001, G2 vs. G3: p < 0,001). Conclusão: A ausência de RIRA confirma o diagnóstico de colopatia chagásica e endossa o tratamento cirúrgico sempre que o tratamento clínico falhar. A presença de RIRA em pacientes com sorologia positiva para doença de Chagas, sem megacólon/megarreto, pode não ser devida à colopatia chagásica e outras causas devem ser consideradas.

ABSTRACT Routine adoption of laparoscopy in clinical practice and Medical Residency has not been widely evaluated in Brazil so far. Aim: To take an overview on the adoption and limitations concerning the use of laparoscopic techniques among Brazilian colorectal surgeons. Methods: A questionnaire was sent to 1870 SBCP filiated members, containing personal and professional data such as sex, age, length and local of practice, SBCP filliation, number of procedures, treatment of cancer and laparoscopy limitations. Results: 418 members (22.4%) sent their response (80% men and 20% women). 110 members (26.3%) affirmed they don't perform any laparoscopic procedure, while 308 (73.7%) have already adopted laparoscopy as a routine. An average number of 7.6 laparoscopic colorectal procedures were declared to be performed per month (1 to 40 procedures). Laparoscopic adoption rates were favourably influenced by young age members (46% vs. 28%) and affiliation to University hospitals (p = 0.01). Conversely, surgeons from private clinic showed a greater tendency of no adoption. Among the 308 responders, 106 (34.4%) have already surpassed more than 100 laparoscopic cases, and 167 (54.2%) reported an experience of more than 50 operated patients. The group of surgeons not using minimally invasive techniques incriminated lack of training (73.6%) and laparoscopic instruments availability (27.3%) as the main reasons for no adoption. Conclusions: Adoption rate of laparoscopic techniques to treat colorectal diseases is still low (at least 17%). Future efforts should focus on providing supervised training, proctorship during the initial experience and help instrumental acquisition in centers willing to change their routine and perspectives.

RESUMO Durante as últimas décadas, a incorporação de técnicas minimamente invasivas no tratamento de doenças colorretais testemunhou um progresso lento e firme, principalmente após o reconhecimento da segurança oncológica e melhor evolução. A adoção rotineira na prática clínica e na Residência Médica no Brasil ainda não amplamente avaliada até agora. Objetivos: O presente estudo visou avaliar a adoção e as limitações relativas ao uso de técnicas laparoscópicas entre cirurgiões colorretais brasileiros. Métodos: um questionário foi enviado a 1870 membros filiados à Sociedade Brasileira de Coloproctologia (SBCP) em 2006. As questões foram enviadas por email, incluindo dados pessoais (sexo, idade) e profissionais (tempo e local de prática, filiação à SBCP, número mensal de procedimentos laparoscópicos, tratamento de câncer e limitações para realizar laparoscopia na rotina. Resultados: Entre os 1870 membros, 418 (22.4%) mandaram sua resposta, com uma maior participaçãoo de homens (80%) em comparação às mulheres (20%). A idade média foi de 43 (28-80) anos. A distribuição entre membros titulares e não titulares foi semelhantes (48% vs. 52%). As atividades profissionais foram desenvolvidas em clínica privada (84%), hospitais privados (73%), hospitais públicos (50%) e hospitais universitários (53%). Entre os que responderam (418), 110 (26.3%) não realizavam procedimentos laparoscópicos, enquanto 308 (73.7%) já haviam adotado o acesso laparoscópico rotineiramente na prática clínica. Um número médio de 7.6 procedimentos colorretais laparoscópicos são realizados por mês (1-40). Cerca de 13% dos cirurgiões iniciaram sua experiência laparoscópica diretamente com procedimentos colorretais, enquanto a maioria (87%) começaram por outros procedimentos no trato digestivo. A adoção da laparoscopia foi positivamente influenciada pela idade jovem dos membros (46% vs. 28%) e pela filiação a hospitais universitários (p = 0,01). Inversamente, cirurgiões trabalhando na prática privada demonstraram uma menor tendência em adotar o método. A maioria dos cirurgiões (93%) que adoraram a laparoscopia afirmou incluir pacientes com câncer colorretal em suas indicações operatórias. Entre os que responderam 106 (34,4%) já realizaram mais de 100 procedimentos laparoscópicos, e 167 (54,2%) reportaram experiência maior que 50 casos. Dentre aqueles que não adotaram técnicas minimamente invasivas, a falta de treinamento (73,6%) ou a indisponibilidade de instrumental laparoscópico (27,3%) foram incriminadas como os principais fatores limitantes. Conclusões: o índice de adoção de técnicas laparoscópicas no tratamento de doenças intestinais ainda é baixo (pelo menos 17%) entre cirurgiões colorretais brasileiros. Esforços futuros de nossa Sociedade Médica devem focar na provisão de treinamento supervisionado, na criação de oportunidades para preceptoria durante a experiência inicial e na obtenção de instrumental em centros que queiram mudar sua rotina e perspectivas.

BACKGROUND/AIMS: Statins have been postulated to lower the risk of colorectal neoplasia. No studies have examined any possible chemopreventive effect of statins in patients with inflammatory bowel disease (IBD) undergoing colorectal cancer (CRC) surveillance. This study examined the association of statin exposure with dysplasia and CRC in patients with IBD undergoing dysplasia surveillance colonoscopies. METHODS: A cohort of patients with IBD undergoing colonoscopic surveillance for dysplasia and CRC at a single academic medical center were studied. The inclusion criteria were IBD involving the colon for 8 years (or any colitis duration if associated with primary sclerosing cholangitis [PSC]) and at least two colonoscopic surveillance exams. The exclusion criteria were CRC or high-grade dysplasia (HGD) prior to or at enrollment, prior colectomy, or limited ( < 30%) colonic disease. The primary outcome was the frequency of dysplasia and/or CRC in statin-exposed versus nonexposed patients. RESULTS: A total of 642 patients met the inclusion criteria (57 statin-exposed and 585 nonexposed). The statin-exposed group had a longer IBD duration, longer follow-up period, and more colonoscopies but lower inflammatory scores, less frequent PSC and less use of thiopurines and biologics. There were no differences in low-grade dysplasia, HGD, or CRC development during the follow-up period between the statin-exposed and nonexposed groups (21.1%, 5.3%, 1.8% vs 19.2%, 2.9%, 2.9%, respectively). Propensity score analysis did not alter the overall findings. CONCLUSIONS: In IBD patients undergoing surveillance colonoscopies, statin use was not associated with reduced dysplasia or CRC rates. The role of statins as chemopreventive agents in IBD remains controversial.

RESUMEN Fundamento: La enfermedad inflamatoria intestinal comprende la colitis ulcerativa idiopática y la enfermedad de Crohn. En la patogenia intervienen factores genéticos y ambientales como la alteración de las bacterias luminales y el aumento de la permeabilidad intestinal, factores que alteran la inmunidad intestinal, causas estas de lesión gastrointestinal. Objetivo: Analizar la influencia de la dieta en la microbiota intestinal en la enfermedad inflamatoria intestinal, así como concientizar a los profesionales de la salud en la importancia de la terapia a partir de la dieta, como pilar esencial en el control de esta enfermedad digestiva crónica. Metodología: Se realizó una búsqueda en bases de datos como: Scielo, Pubmed/Medline, Ebsco, Clinical Key, Springer, Web of Science, Infomed, se incluyeron revistas, libros, repositorios de tesis, sitios web de especialidades. Desarrollo: En los pacientes con enfermedad inflamatoria intestinal existe una disbiosis que contribuye potencialmente a una respuesta inmune proinflamatoria. Conclusiones: El equilibrio entre el huésped y su microbiota intestinal es esencial para el desarrollo inmunológico óptimo; la modificación de la dieta y la flora bacteriana intestinal son dianas potenciales en el tratamiento y prevención de la misma.

ABSTRACT Background: Inflammatory bowel disease includes idiopathic ulcerative colitis and Crohn's disease. In the pathogenesis are present genetic and environmental factors such as alteration of luminal bacteria and increased intestinal permeability, factors that alter the intestinal immunity, these causes of gastrointestinal injury. Objective: To analyze the influence of diet on intestinal microbiota in inflammatory bowel disease, as well as to increase awareness among health professionals about the importance of diet-based therapy as an essential pillar in the control of this chronic digestive disease. Methodology: A search was made in databases such as: Scielo, Pubmed / Medline, Ebsco, Clinical Key, Springer, Web of Science, Infomed, magazines, books, thesis repositories, and specialty websites. Development: In patients with inflammatory bowel disease there is a dysbiosis that potentially contributes to a proinflammatory immune response. Conclusions: The balance between the host and its intestinal microbiota is essential for the optimal immunological development; the modification of the diet and the intestinal bacterial flora are potential targets in the treatment and prevention of it.
