Proctitis y enfermedad perianal de causa infecciosa: una mirada más allá de la enfermedad inflamatoria intestinal / Infectious proctitis and perianal disease: a gaze beyond inflammatory bowel disease

Resumen La proctitis infecciosa secundaria a una enfermedad de transmisión sexual ha aumentado en incidencia y deben ser consideradas especial-mente en varones homosexuales o bisexuales con síntomas rectales. Presentamos un paciente con una proctitis y enfermedad perianal por Chlamydia trachomatis que podría haber sido diagnosticado con otra enfermedad ano-rectal como es la enfermedad inflamatoria intestinal, si la historia clínica no hubiese sido considerada. Un alto nivel de sospecha es necesario para evitar un diagnóstico incorrecto, retrasar el tratamiento antimicrobiano y el desarrollo de complicaciones.

Abstract Infectious proctitis by sexually transmitted diseases are increasing in incidence and should be considered in homosexual patients with rectal symptoms. In this case, we show a patient with proctitis and perianal disease caused by Chlamydia trachomatis that could be diagnosed as another anorectal disease such as inflammatory bowel disease if the clinical history is not taken into account. A high level of suspicion is crucial, in order to avoid an incorrect diagnosis, delayed antibiotic therapy and the development of complications.

Risk factors associated with progression to intestinal complications of Crohn disease / 中华医学杂志(英文版)

Background@#Crohn disease is a chronic bowel disease that causes serious complications. Prevalence of Crohn disease is increasing. Studies have shown that the behavior of the disease is not stable and severe complications secondary to behavior change over time have been shown. In this study, we aimed to evaluate the prognostic risk factors associated with phenotypic change in Crohn disease in a Turkish patient cohort.@*Methods@#Patients followed up from March 1986 to August 2011 were evaluated for demographic and clinical characteristics to determine possible risk factors and initial clinical phenotype of the disease based on the Montreal classification. The cumulative probabilities of developing stricturing or penetrating intestinal complications were estimated using the Kaplan-Meier analysis. Univariate and multivariate Cox-proportional hazard models were used to assess associations between baseline clinical characteristics and intestinal complications.@*Results@#Three hundred and thirty patients (mean age, 30.6 ± 11.1 years; 148 female) were included in the study. Mean follow-up duration was 7.4 ± 5.3 years (range: 1.0-25.0 years). At baseline 273 patients had inflammatory-type disease, 57 patients experienced stricturing/penetrating intestinal complications before or at the time of diagnosis. The cumulative probability of developing complicated disease was 37.4% at 5 years, 54.3% at 10 years, 78.8% at 25 years. Independent predictors associated with progression to intestinal complications were current smoking, perianal disease, extra-intestinal manifestations, and location of disease.@*Conclusions@#Location of disease is the most powerful indicator for the development of stenosis and penetrating complications in inflammatory-type disease. Patients with ileal involvement should be considered for more aggressive immunosuppressive therapy.

Clinical Characteristics and Incidence of Perianal Diseases in Patients With Ulcerative Colitis

PURPOSE: While perianal disease (PAD) is a characteristic of patients with Crohn disease, it has been overlooked in patients with ulcerative colitis (UC). Thus, our study aimed to analyze the incidence and the clinical features of PAD in patients with UC. METHODS: We reviewed the data on 944 patients with an initial diagnosis of UC from October 2003 to October 2015. PAD was categorized as hemorrhoids, anal fissures, abscesses, and fistulae after anoscopic examination by experienced proctologists. Data on patients’ demographics, incidence and types of PAD, medications, surgical therapies, and clinical course were analyzed. RESULTS: The median follow-up period was 58 months (range, 12–142 months). Of the 944 UC patients, the cumulative incidence rates of PAD were 8.1% and 16.0% at 5 and 10 years, respectively. The incidence rates of bleeding hemorrhoids, anal fissures, abscesses, and fistulae at 10 years were 6.7%, 5.3%, 2.6%, and 3.4%, respectively. The cumulative incidence rates of perianal sepsis (abscess or fistula) were 2.2% and 4.5% at 5 and 10 years, respectively. In the multivariate analyses, male sex (risk ratio [RR], 4.6; 95% confidence interval [CI], 1.7–12.5) and extensive disease (RR, 4.2; 95% CI, 1.6–10.9) were significantly associated with the development of perianal sepsis. CONCLUSION: Although the clinical course of PAD in patients with UC is not serious, in clinical practice, PAD is not rare in such patients. Therefore, careful examination and appropriate management for PAD is needed if the quality of life for patients with UC is to be improved.

Enfermedad de Crohn fistulizante: manejo actual y su aplicabilidad en la realidad nacional / Fistulizing Crohn’s disease, current management and its applicability in the national reality

The development of fistulas during the evolution of Crohn’s Disease represents a severe situation that affects quality of life and requires a multidisciplinary care approach that involving gastroenterologists, surgeons and radiologists. Fistulizing Crohn’s disease can be divided in perianal and not perianal disease. Perianal disease can also be divided in simple or complicated disease depending on the fistula’s characteristics that will guide the clinical and therapeutic approach. Fistulizing not perianal disease can be internal when it communicates the bowel with other organs (colovesical, rectovaginal or enteroenteric fistulas), and external when it communicates the bowel with the abdominal wall (enterocutaneous fistula), either as a spontaneous or post-surgical phenomenon. Given the variety of fistula presentation, it is necessary to give an individualized approach, taking into account the fistula’s route, the inflammatory bowel activity, the presence of abscesses, and the nutritional status of the patient. This review is focused on the current management of fistulizing Crohn’s disease in our country.

El desarrollo de fistulas durante la evolución de la enfermedad de Crohn es una situación grave que condiciona una peor calidad de vida, así como mayor complejidad en el enfrentamiento, debiendo involucrar la colaboración multidisciplinar entre gastroenterólogos, cirujanos y radiólogos. La enfermedad fistulizante se divide en aquella que afecta la zona perianal (enfermedad perianal) y en aquella que no afecta la zona perianal. La enfermedad perianal a la vez se dividirá en simple o compleja dependiendo de las características de las fistulas, lo cual condiciona variaciones en el enfrentamiento y tratamiento. La enfermedad fistulizante no perianal se divide en interna cuando comunica al intestino con otros órganos (fistulas entero-vesicales, entero-vaginales, entero-entérico) y externas cuando se comunica al intestino con la pared abdominal (fistulas entero-cutáneas) tanto de forma espontánea como postquirúrgica. Debido a la gran diversidad de presentación de las fistulas es necesario individualizar cada grupo de trayectos fistulosos, valorar la asociación a actividad inflamatoria luminal, descartar la presencia de abscesos y valorar el estado nutricional de los pacientes para definir el manejo integral adecuado. Este artículo se centra en el manejo actual de la enfermedad de Crohn fistulizante en nuestro país.
