ABSTRACT
Background: The incidence and prevalence of Inflammatory Bowel Disease (IBD) has increased. Aim: To determine demographic and clinical characteristics of patients with IBD in a Chilean private hospital. Patients and Methods: Review of a prospective registry of patients with IBD, started on 2012. It includes clinical, imaging, endoscopical and pathological information of patients. Results: Data of 316 patients with IBD, aged 16 to 86 years (56% females), were analyzed. Ulcerative Colitis (UC), Crohn´s and non-classifiable IBD were diagnosed in 230, 77 and 9 patients, respectively. The disease was diagnosed in 82% of patients in the period between 2002 and 2012. There was a peak in the diagnosis of both UC and CD between 20 and 39 years of age, without gender differences. The disease switched from UC to CD in six patients. In four, there was a change in disease behavior. Thirty eight patients were treated with biological therapy. The median lapse between the diagnosis and the use of biological therapy was 1 year in patients diagnosed after 2007, compared with 5.5 years among those patients diagnosed before 2007 (p = 0.001). There was a trend towards a higher requirement of surgery until 2006. Subsequently there was a stabilization of the requirement, concomitant with the incorporation of biological therapy. Conclusions: An adequate registry of IBD patients is necessary to improve demographic and clinical characteristics. A national registry is needed to assess the epidemiological changes of IBD in Chile.

Introducción: En la actualidad hay consenso en la seguridad oncológica en la cirugía laparoscópica para el tratamiento del cáncer de colon, sin embargo, en el cáncer de recto (CR) los resultados a largo plazo, continúan siendo objeto de estudio. El objetivo de este trabajo es analizar la sobrevida a largo plazo en pacientes operados por adenocarcinoma de recto por vía laparoscópica. Material y Métodos: Desde la base de datos prospectiva de cirugía colorrectal laparoscópica se seleccionaron los pacientes operados por CR en el periodo entre octubre 2000 y diciembre 2009. Se excluyó a los pacientes con cáncer colorrectal hereditario. Se analizaron los datos de seguimiento los cuales son obtenidos mediante registros clínicos y datos del registro civil. Se realizó un análisis de sobrevida con el método de Kaplan-Meier. Resultados: En el periodo mencionado, 60 pacientes fueron operados por CR, 2 (3,4%) pacientes fallecieron en el postoperatorio temprano y fueron excluidos en el análisis de sobrevida, por tanto, 58 pacientes fueron incluidos en el seguimiento. El 41% eran sexo femenino y la edad promedio fue de 60 ± 11,6 años. Los tumores se encontraban localizados en el recto superior, medio e inferior en un 28%, 28% y 44% respectivamente. Las cirugías realizadas fueron resección abdominoperineal, resección anterior ultrabaja interesfintérica, resección anterior ultrabaja y resección anterior baja en un 8%, 28%, 5% y 59% de los pacientes, respectivamente. El 50% de los pacientes recibieron neoadyuvancia. Tras la estadificación postoperatoria 4% fueron clasificados estadio 0, 38% estadio I, 17% estadio II, 28% estadio III y 13% estadio IV. El recuento de linfonodos de la pieza operatoria fue de 12,3 en promedio. A un seguimiento de 42,6 meses (r: 17 a 103 meses) la sobrevida global estimada a 5 años es de 85%. Según estadios la sobrevida estimada a 5 años fue de 100% para el estadio 0 y I, 88% para el estadio II, 74% para el estadio III... (TRUNCADO)
Background: Currently there is a consensus in oncological safety for laparoscopic surgery for colon cancer; however, in rectal cancer long term outcomes are still a subject of debate. The aim is to analyze long term survival in patients who underwent laparoscopic surgery for rectal cancer. Material and Methods: From the prospective database of laparoscopic colorectal surgery, we selected patients operated on between October 2000 and December 2009. Patients with hereditary colorectal cancer were excluded. Follow-up data was obtained by medical records and national vital records. Survival was analyzed using the Kaplan-Meier method. Results: In this period, 60 patients were operated on for rectal cancer. Two died in the early postoperative period and were excluded from the analysis; therefore, 58 patients were included in follow-up. Forty-one percent were female and mean age was 60±11.6 years old. Tumors were localized in the upper, mid and lower rectum in 28%, 28% and 44%, respectively. Surgeries performed were abdominoperineal resection, ultra-low intersphincteric resection, ultralow anterior resection and low anterior resection in 8%, 28%, 5% and 59% of patients, respectively. Fifty percent received neoadjuvant treatment. After postoperative staging 4% were classified as stage 0,17% as stage I, 28% as stage II, 28% as stage III, and 13% as stage IV. At a mean 42.6 month follow-up (r: 17-103 months) estimated overall 5-year survival was 85%. When analyzed according to stage, estimated overall 5-year survival was 100% for stages 0 and I, 88% for stage II, 74% for stage III, and 57% for stage IV. Conclusion: Long term survival in patients undergoing laparoscopic surgery for rectal cancer is satisfactory and is within the values reported by international centers.
