RESUMEN
Introduction: Preoperative T staging of rectal cancer is essential for an adequate treatment strategy. Endoscopic ultrasonography (EUS) is one of the available modalities. The reported accuracy of this technique for T staging is variable. This inconsistency might be due to neoadyuvancy, and its downstaging properties. Aim: Determine the accuracy of rectal EUS for T staging of middle and lower rectal tumors in patients not treated with neoadyuvant chemo-radiotherapy. Materials and Methods: Clinical records of all consecutive patients evaluated by rectal EUS between years 2001-2009 in the Catholic University Clinical Hospital were accessed. Of 2.120 patients, 294 had the exam performed for middle or lower rectal cancer. Those who did not receive neoadyuvant chemo-radiation and whose histopathology was available were analyzed. Result: Data was obtained for 69 patients. The overall accuracy of EUS for T staging was 85 percent. For T1 tumors, the sensibility, specificity and accuracy were 82 percent, 96 percent and 94 percent respectively. For T2 tumors the sensibility, specificity and accuracy were 72 percent, 83 percent and 78 respectively. For T3 tumors the sensibility, specificity and accuracy were 82 percent, 83 percent and 83 percent respectively. Conclusion: Rectal EUS continues to be a valuable staging procedure for tumor depth invasion, with an overall accuracy of 85 percent.
Introducción: La estadificación tumoral (T) preoperatoria es esencial para el tratamiento del cáncer de recto. La endosonografía rectal (ER) es una de las modalidades disponibles. La exactitud de esta técnica para la estadificación tumoral es variable en la literatura, y se sospecha que esta inconsistencia se debe a la neoadyuvancia, por el descenso de estadio que esta produce. Objetivo: Analizar la exactitud de la endosonografía rectal para la estadificación tumoral en pacientes con cáncer de recto medio o inferior que no hayan recibido neoadyuvancia. Material y Método: Se estudió a los pacientes sometidos a endosonografía rectal entre los años 2001-2009 en el Hospital Clínico de la Pontificia Universidad Católica de Chile. De un total de 2.120 pacientes, 294 fueron evaluados por cáncer de recto en tercio medio o inferior. Se analizó el examen de aquellos que no recibieron quimio-radioterapia preoperatoria y se encontraba disponible la anatomía patológica para su comparación. Resultados: Se obtuvo información de 69 pacientes. La exactitud global del examen para la determinación del T fue 85 por ciento. Para la determinación de T1 los valores de sensibilidad, especificidad y exactitud fueron 82 por ciento, 96 por ciento y 94 por ciento respectivamente. Para T2 los valores de sensibilidad, especificad y exactitud fueron 72 por ciento, 83 por ciento y 78 por ciento respectivamente. Para T3 los valores de sensibilidad, especificidad y exactitud fueron 82 por ciento, 83 por ciento y 83 por ciento respectivamente. Conclusión: La endosonografía rectal sigue siendo un valioso examen para la determinación de la profundidad de invasión tumoral en cáncer de recto con una exactitud global de 85 por ciento.

Background: The usual surgical management of acute diverticulitis is Hartmann operation that is associated with high rates of complications and mortality. Recently, less invasive procedures, that avoid ostomies have been proposed as treatment, Alm: To analyze the results of laparoscopic peritoneal lavage in patients with acute diverticulitis. Material and Methods: Prospective analysis of seven patients age 25 to 61 years (four males) admitted for a first episode of acute diverticulitis classified as Hinchey II or III, in whom a percutaneous drainage of collections was not possible. All were subjected to a laparoscopic peritoneal lavage and debridement. Results: The mean body mass index of patients was 30.3 kg/m². Operative time was 55 +/- 28 min and there was no need for ostomies or conversion to open surgery. Two patients had complications. One required a percutaneous drainage of a collection and other required an open surgical procedure for peritoneal lavage. Patients stayed with nil per os for 2 +/- 1 days, required antimicrobials for 14 +/- 4 days and stayed in the hospital for 8 +/- 4 days. Conclusions: Laparoscopic peritoneal lavage is a good alternative surgical procedure for the treatment of acute diverticulitis.
Introducción: Tradicionalmente, el manejo quirúrgico de la diverticulitis aguda complicada (DAC) ha sido la operación de Hartmann. Sin embargo, ésta presenta tasas de morbilidad de 59 por ciento y mortalidad hasta de 12 por ciento. Han aparecido algunos procedimientos no resectivos con algunas ventajas operatorias y que evitarían la confección de una ostomía. Objetivo: Analizar resultados quirúrgicos de una serie de pacientes con DAC sometidos a lavado peritoneal sin resección por vía laparoscópica (LPL). Pacientes y Métodos: Serie de registro prospectiva de siete pacientes, que ingresaron con diagnóstico de DAC Hinchey II en que no fue posible el drenaje percutáneo de las colecciones y pacientes categorizados como Hinchey III, operados entre octubre de 2008 y noviembre de 2010. Resultados: Cuatro pacientes eran de sexo masculino. La edad media fue de 49 años, con un IMC de 30,3 kg/m². Todos los pacientes ingresaron con su primer episodio de DA. El tiempo operatorio fue de 55 +/- 28 minutos. No hubo necesidad de ostomía ni conversión. Dos pacientes presentaron complicaciones que requirieron de nuevos procedimientos durante su estadía. El tiempo de reposo digestivo fue de 2 +/- 1 días y la duración del esquema antibiótico fue de 14 +/- 4 días. La estadía hospitalaria fue de 8 +/- 4 días. Conclusiones: El LPL representa una alternativa al manejo quirúrgico tradicional. Las ventajas teóricas son bajas tasas de morbimortalidad, estadía hospitalaria más corta y sin la eventual necesidad teórica de una ostomía. Esta técnica requiere ser validada en el contexto de un estudio aleatorizado con claridad en criterios de inclusión y exclusión.

The development of laparoscopic colorectal surgery began 20 years ago; however it took several years before gaining its acceptance by the international surgical community. The first report in Chile was published in 1995. However, were necessary many years, until the middle of this decade, to know the first prospective series experiences. Out of these reports, no reliable data exist regarding the development of laparoscopic colorectal surgery in Chile, related to the number of centers performing laparoscopic colorectal surgery or the number of procedures performed. For record these data, a standardized questionnaire was send to colorectal chairmans of all hospitals that had reported to be developing laparoscopic colorectal surgery in our country. Ten of 15 hospitals responded to the survey. Most of the procedures performed were hemicolectomies, principally for cancer and diverticular disease. The average conversion rate was 7 percent and hospital stay was 5 days. Morbidity and mortality rates were 12 percent and 0.4 percent respectively. In the last year was seen an increase in the number of laparoscopic procedures in relation to the previous period. In conclusion, laparoscopic colorectal surgery is a recent technique in Chile, which is being implemented progressively, with good overall results.
El desarrollo de la cirugía laparoscópica colorrectal (CLCR) se inició en la década de los 90, sin embargo, pasaron varios años antes de lograr su aceptación por la comunidad quirúrgica internacional. En Chile, los primeros relatos en congresos datan del año 1995 y las primeras experiencias de series prospectivas fueron publicadas 10 años más tarde. Fuera de estos reportes, no existe información fidedigna en relación al desarrollo de la cirugía laparoscópica colorrectal en Chile, relacionados con el número de centros que la realizan, la formación actual de los cirujanos colorrectales en esta técnica ni en cuanto al número de procedimientos realizados. Para conocer estos datos se envió una encuesta estandarizada a los jefes de equipo de los centros que habían comunicado estar desarrollando la CLCR en nuestro país. Diez de 15 centros respondieron la encuesta. La mayor parte de los procedimientos corresponden a hemicolectomías, siendo las principales indicaciones el cáncer y la enfermedad diverticular. La tasa de conversión promedio fue de 7 por ciento y la estadía hospitalaria de 5 días. La morbilidad y mortalidad fue de 12 por ciento y 0,4 por ciento respectivamente. En el último año se ha visto un aumento del número de procedimientos laparoscópicos en relación al período previo. En conclusión, La CLCR es una técnica de reciente incorporación en Chile, que está siendo implementada en forma progresiva, con buenos resultados globales.

Background: During the perioperative period an adequate intravascular volume must be maintained. Current recommendations overestimate perioperative volume requirements. Aim: To compare perioperative volume administration using standard monitoring methods or guided by left ventricular filling parameters. Material and Methods: Twenty-four patients subjected to colon resection were randomized to monitoring by electrocardiography, blood and central venous pressure, or by transesophageal echocardiography. In the latter, volume administration was adjusted to maintain basal values of left ventricular end diastolic volume and cardiac index. Results: Patients with the standard monitoring system and transesophageal echocardiographic monitoring received 21.1±12 and 6.3 ± 2 ml/kg/h of fluids during the perioperative period, respectively (p < 0.01). Conclusions: The use of transesophageal echocardiography significantly reduced the perioperative fluid administration.

Background: Conversion to open surgery of laparoscopic procedures is not in essence a complication, but invalidates the benefits of laparoscopy. Aim: To identify the predictive factors for conversion in laparoscopic colorectal surgery. Material and Methods: Revision of medical records of all patients with colorectal disease operated using a laparoscopic approach, from 1998 to 2010. Gender, age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), previous abdominal surgery, elective/urgency procedure, benign/malignant disease, type of resection and surgeon experience were recorded. A logistic regression model was done to determine which variables were predictive for conversion to open surgery. Results: The medical records of 582 patients aged 57 +/- 17 years (45 percent men) were analyzed. The rate of conversion to open surgery was 7.1 percent. The logistic regression model selected as predictors of conversion a BMI over 25 kg/m² (odds ratio (OR) 4.9, 95 percent confidence intervals (CI) 2.4 to 9.9), cancer surgery (OR 2.1, 95 percent CI 1.1 to 4.3) and male sex (OR 2.30, 95 percent CI 1.14 to 4.65). The receiver operating curve (ROC) of the model had an are under the curve of 0.766 with 95 percent CI of 0.69 to 0.84). Conclusions: A BMI over 25 kg/m², male sex and the resection of a malignant tumor were predictive factors for conversion to open surgery.
Objetivo: Identificar los factores de riesgo para la conversión en la cirugía laparoscópica colorrectal. Material y Método: Se revisó la base de datos prospectiva de cirugía laparoscópica colorrectal, desde 1998 a 2010. Se analizaron las variables: sexo, edad, ASA, IMC, presencia de cirugía abdominal previa, procedimiento electivo/urgencia, patología benigna/maligna, tipo de resección y experiencia del cirujano. Se realizó un análisis uni y multivariado. Para determinar las variables predictivas de conversión, la totalidad de estas fueron incluidas en un modelo de regresión logística. Resultados: De un total de 621 pacientes consecutivos, la serie se compuso de 582 pacientes (hombres: 45 por ciento, edad promedio: 56,3 años) Tasa de conversión 7,1 por ciento. El modelo de regresión logística seleccionó tres variables como predictivas de conversión: IMC > 25 kg/m² (OR 4,88; IC95 por ciento 2,40-9,92), cirugía por cáncer (OR 2,12; IC95 por ciento 1,11-4,29) y sexo masculino (OR 2,30; IC95 por ciento 1,14-4,65). No fueron predictivas de conversión: edad, comorbilidades, experiencia del cirujano, tipo de procedimiento, ni cirugía previa. La calibración del modelo fue satisfactoria, al igual que su capacidad de discriminación (ABC ROC = 0,766). Conclusiones: En este estudio el IMC sobre 25 kg/m², el sexo masculino y las resecciones por cáncer son factores predictivos independientes de conversión. Este modelo predictivo mostró una calibración satisfactoria, asociada a una capacidad de discriminación acertada para el evento en estudio.

Among patients with short bowel syndrome, surgical small intestine lengthening techniques are employed to increase the absorptive surface. Among these, serial transverse enteroplasty involves transecting the bowel transversally, preserving the blood supply of the small intestine and creating a longer segment of bowel. We report a 51-year-old woman with a short bowel syndrome and multiple hospital admissions for complications. She was subjected to a serial transverse enteroplasty, increasing small intestinal length from 140 to 180 cm. During the postoperative period, she presented intra abdominal blood collections and a septic episode with bacterial endocarditis. One month after the operation, total parenteral nutrition was discontinued and nutritional and fluid balances were achieved using exclusively the oral route. During the ambulatory follow up, the patient continues with exclusive oral feeding and five bowel movements per day.

Ulcerative colitis (UC) is a chronic inflammatory disease of unknown etiology that affects a variable length of the colon, starting from the rectum. When the disease is confined to the rectum is called ulcerative proctitis (UP). Several studies have unsuccessfully attempted to determine the factors that determine the extent of involvement. The goals of therapy in UP are to induce and maintain remission of symptoms and disease. Topical treatment with 5-aminosalicylates (5-ASA) is the treatment of choice to induce remission. In the maintenance phase, long-term follow up studies suggest that treatment with 5-ASA is better than placebo, to maintain the disease inactive. For those patients that do not respond to treatment with topical 5-ASA or have a moderate to severe disease, there are additional therapies such as oral 5-ASA, topical or systemic corticosteroids, immunomodulators, biological therapies (Infliximab) and cyclosporine. Surgery is seldom needed.

In the era of HIV infection there is a resurgence of syphilis. Without a doubt it is still a diagnostic dilemma in various clinical situations such as anorectal syphilis in HIV patients. When a patient HIV-positive presents with a rectal tumor, syphilis must be considered in the differential diagnosis. We present a case report of an HIV positive patient who consulted due to rectal tenesmus associated to rectal bleeding, being diagnosed a rectal tumor and treated secondary to primary syphilis.
En la era de la infección por VIH, ha habido un resurgimiento de enfermedades en franca disminución en el mundo occidental como sífilis. Sin lugar a dudas siguen siendo un dilema diagnóstico algunas manifestaciones clínicas como sífilis rectal en pacientes portadores de VIH. Frente a un tumor rectal en un paciente VIH se debe tener en cuenta en el diagnóstico diferencial a esta patología. Presentamos un caso de un paciente portador de VIH que consultó por tenesmo rectal asociado a rectorragia, siendo diagnosticado un tumor rectal secundario a sífilis primaria.

BACKGROUND: Total colectomy with ileorectal anastomosis (IRA) is an alternative to the ileoanal pouch for the surgical treatment of ulcerative colitis in a selected group of patients. This technique leaves rectal mucosa liable to develop persistent proctitis, dysplasia and cancer. AIM: To describe short and long-term results of IRA and to assess the presence of dysplasia. MATERIAL AND METHODS: Descriptive study of patients treated with IRA. The data were obtained from the clinical records, and the present status was evaluated with an interview. A proctoscopy and biopsy was offered free of cost to the contacted patients. RESULTS: Between 1978 and 2005, 26 patients were operated. One patient presented an anastomotic leakage that was treated with a loop ileostomy. There was no operative mortality. Twenty-three patients were followed for a period of 1 to 23 years. Three patients evolved as Crohn 's disease and two of them needed a proctectomy. Three patients died of non-related diseases. In the remaining 17, the average evacuation rate was 3.7/24 h and all were continent. None developed a rectal cancer Only two patients had their planned annual endoscopic surveillance. In 2 of the 11 patients who accepted endoscopy and biopsy, a low-grade dysplasia was found. CONCLUSIONS: IRA has low morbidity and acceptable functional results in this selected group of patients. No patient presents high-grade dysplasia or cancer; however, the adherence to the endoscopic follow-up is poor.

Introducción: El abordaje laparoscópico en el tratamiento de la inercia colónica (IC) es una técnica que ha demostrado ser una excelente alternativa al abordaje clásico. Objetivo: Presentar la experiencia de la IC y los resultados funcionales obtenidos a mediano plazo luego de una colectomía total con ileorecto anastomosis (CT+IRA) por vía laparóscopica. Material y Método: Se analizaron todos los pacientes operados con diagnóstico de IC a los que se les realizó una CT+IRA vía laparóscopica, en el período 2002 al 2007. Todos poseían un completo estudio para constipación (Historia clínica, manometría ano-rectal, enema baritado, defecografía, estudio radiológico del tránsito colónico y de intestino delgado). Se analizaron las variables preoperatorios y quirúrgicas. Se realizó un seguimiento telefónico evaluando el puntaje según la escala de Wexner para constipación e incontinencia, la recomendación de la cirugía a terceros y satisfacción con el procedimiento (Escala de 1 a 10). Análisis estadístico: Test T de Student. Resultados: En el período mencionado se intervinieron 20 pacientes, todos de sexo femenino. La edad promedio fue de 41,5 años (i: 18-52). El tiempo operatorio fue de 248 minutos (i: 170-360). Hubo una conversión (5 por ciento) por dificultad anatómica. El tiempo medio hasta la expulsión de gases y la realimentación fue al 2º (i: 1-4) y 3º (i: 2-6) día respectivamente. La mediana de estadía postoperatoria fue de 7 días. Se complicaron 7 pacientes (35 por ciento) (3 íleo postoperatorios, 1 trombosis portal, 1 rectorragia, 1 colección peri anastomotica y 1 hemoperitoneo). Hubo una relaparotomía por trombosis portal, una punción percutánea por colección perianastomotica y una relaparoscopía por hemoperitoneo. No hubo mortalidad postoperatoria. Seguimiento a una mediana de 25 meses (i: 1-60); puntaje de Wexner para constipación en el preoperatorio fue 22,3 (i: 19-29) y al control postoperatorio 1,8 (i: 0-6) (p < 0,01).

Background: Total colectomy with Neo-recto anastomosis has the best results in the treatment of colonic inertia but it is a complex procedure. Laparoscopic approach is a less invasive alternative. Aim: To report the results of laparoscopic total colectomy with Neo rectal anastomosis for the treatment of colonic inertia. Material and Methods: Review of medical records of patients with colonic inertia subjected to a laparoscopic total colectomy with Neo rectal anastomosis. All had a complete preoperative study for constipation. A telephone follow up was performed asking for constipation, fecal incontinence and if they would recommend the procedure to other patients. Results: Twenty female patients aged 18 to 52 years were operated. Mean operative time was 248 minutes. In 5 percent of patients, conversion to open surgery was required. The lapse for gas expulsion and resumption of oral feeding was two and three days after surgery, respectively. Mean hospital stay was seven days. Seven patients (35 percent) has complications (a postoperative ileus in three, a portal vein thrombosis in one, hematochezia in one and hemoperitoneum that required a new laparoscopy in one). The Wexler score for constipation was 22.3 (range 19-29) in the preoperative period and decreased to 1.8 (range 0-6) in the telephone follow up. The mean level of satisfaction was 8 (range 2-10) and only one patient would not recommend the procedure to other patients. Conclusions: Laparoscopic total colectomy for colonic inertia has a 35 percent rate of complications in immediate postoperative period and good functional results in the long term follow up.

BACKGROUND: The ileo anal-pouch-anastomosis (IPAA) is the treatment of choice for patients with ulcerative colitis (UC). AIM: To analyze the surgical outcomes, long term evolution and functional results of IPAA. MATERIAL AND METHODS: All patients subjected to an IPAA, from 1984 to 2006 were identified from a prospectively constructed inflammatory bowel disease database. Surgical variables, postoperative complications and functional evaluation, using Oresland score were analyzed. Chi square, Fischer exact test, T Student, Mann Whitney and binary logistic regression were included in the statistical analysis. RESULTS: In the study period 107 patients, aged 14 to 62 years (61 females), subjected to an IPAA, were identified in this period. All patients, except 4, had a J pouch. All were protected with a loop ileostomy. Thirteen patients (12.1%) had specific postoperative complications: pelvic collections in five (4.6%), wound infection in four (3.7%), fistula of the anastomosis in two (1.8%), hemoperitoneum and pouch necrosis in one each. Three (2.7%) patients were reoperated. There was no post-operative (30 days) mortality. A complete follow-up was obtained in 106 of 107 patients: four evolved as Crohn disease; four lost their pouch and two died for other causes. One patient required an ileostomy due to a vaginal fistula. Seventy two patients were followed more than 36 months after ileostomy closure and 92% have a satisfactory intestinal function. In the univariate analysis, poorest intestinal function was related to age of diagnosis of UC and presence of chronic pouchitis. In the multivariate analyses age of diagnosis was associated with poor function. CONCLUSIONS: IPAA has a low rate of complications. The long term intestinal function is satisfactory in most patients. A poorer intestinal function was observed in older patients and those with chronic pouchitis).

Introducción: Aproximadamente el 50 por ciento de los pacientes con Enfermedad de Crohn (EC) necesitarán de un tratamiento quirúrgico en algún momento de su evolución. La resección ileocecal (RIC) es una de las operaciones más frecuentes en pacientes con EC. Objetivo: Identificar las indicaciones quirúrgicas y determinar el porcentaje de recurrencia de la enfermedad a largo plazo de los pacientes sometidos a RIC por EC. Material y método: Se incluyeron todos los pacientes sometidos consecutivamente a RIC entre Enero 1970 y Diciembre 2006 y se analizaron características demográficas, indicación operatoria, variables intraoperatorias, complicaciones y, en el seguimiento, la recurrencia de la enfermedad. Resultados: 28 pacientes fueron operados en el periodo mencionado. 17 mujeres (60,7 por ciento), edad promedio del diagnóstico de EC: 34,8 años (i: 14-60) y de la RIC: 43,3 años (i: 16-68). Seis pacientes habían sido operados previamente por EC (3 sobre el periné y 3 resecciones parciales de intestino, no RIC). Una o más de las siguientes condiciones contribuyeron a la indicación quirúrgica: Obstrucción intestinal intermitente en 21 pacientes, refractariedad a tratamiento médico en 10, fístula enteral en 2 y hemorragia digestiva baja en 2. Nueve pacientes (32,1 por ciento) tuvieron una o más complicaciones postoperatorias, 3 (10 por ciento) de los cuales fueron reintervenidos (2 por filtración de la anastomosis, uno por hemoperitoneo). La mediana de estadía postoperatoria fue 9 días. No hubo mortalidad operatoria. En el seguimiento a largo plazo, 3 pacientes desarrollaron Íleo mecánico por bridas. Todos ellos resueltos quirúrgicamente. Cuatro pacientes (14 por ciento) fueron reintervenidos por recidiva de la EC con tiempo medio desde la RIC de 63 meses. La sobrevida a 5 años fue de 96 por ciento. Conclusión: La RIC por EC, se indica principalmente por obstrucción intestinal debida a estenosis. La estenosis en la recidiva de la enfermedad es baja.
Background: Approximately 50 percent of patients with Crohn's disease (CD) will need a surgical treatment in the long term course of the disease. The ileocaecal resection (ICR) is the most common operations in patients with CD. Aim: To identify the surgical indications and to determine the rate of recurrence in late follow up of the patients who underwent ICR for CD. Material and method: Consecutive inclusion of patients submitted to ICR between 1970 and 2006. Demographic characteristics, surgical indications, intraoperative findings, postoperative complications and recurrence of the disease were analyzed. Results: 28 patients had an ICR inthisperiod. Average age at diagnosis of CD 34.8 years (r: 14-60), ICR 43.3 years (r: 16-68). 60.7 percent female gender. Six patients were previously operated for CD (3 over perine and 3 partial resection of small bowel, no ICR). One or more of the following clinical conditions were considered surgical indications: Intermittent intestinal obstruction in 21 patients, failure of medical treatment in 10, enteral fistulae 2 and lower intestinal bleeding 2. Nine patients (32.1 percent) had one or more postoperative complications. 3 (10 percent) of them were re-operated (2 for leakage and fistulae, one for hemoperitoneum). The median postoperative stay was 9 days. There was no postoperative mortality (30 days). In the long term follow up, 3 (10 percent) patients developed intestinal obstruction due to adhesions. All of them needed an operation. Four patients (14 percent) were reoperated for CD with a mean time of 63 months since the ICR. Two of them for stenosis of ileocolic anastomosis and two for perianal abscess and fistulae. The 5 year survival was 96 percent. Conclusion: Stenosis and intestinal obstruction of the terminal ileum is the main indication for ICR.

Background: The ileo anal-pouch-anastomosis (IPAA) is the treatment of choice for patients with ulcerative colitis (UC). Aim To analyze the surgical outcomes, long term evolution and functional results of IPAA. Material and methods: All patients subjected to an IPAA, from 1984 to 2006 were identified from a prospectively constructed inflammatory bowel disease database. Surgical variables, postoperative complications and functional evaluation, using Oresland score were analyzed. Chi square, Fischer exact test, T Student, Mann Whitney and binary logistic regression were included in the statistical analysis. Results: In the study period 107 patients, aged 14 to 62 years (61 females), subjected to an IPAA, were identified in this period. All patients, except 4, had a J pouch. All were protected with a loop ileostomy Thirteen patients (12.1 percent) had specific postoperative complications: pelvic collections in five (4.6 percent), wound infection in four (3.7 percent), fistula of the anastomosis in two (1.8 percent), hemoperitoneum and pouch necrosis in one each. Three (2.7 percent) patients were reoperated. There was no post-operative (30 days) mortality. A complete follow-up was obtained in 106 of 107 patients: four evolved as Crohn disease; four lost their pouch and two died for other causes. One patient required an ileostomy due to a vaginal fistula. Seventy two patients were followed more than 36 months after ileostomy closure and 92 percent have a satisfactory intestinal function. In the univariate analysis, poorest intestinal function was related to age of diagnosis of UC and presence of chronic pouchitis. In the multivariate analyses age of diagnosis was associated with poor function. Conclusions: IPAA has a low rate of complications. The long term intestinal function is satisfactory in most patients. A poorer intestinal function was observed in older patients and those with chronic pouchitis).
