RESUMO

Introducción: El traumatismo anorrectal es una causa poco frecuente de consulta al servicio de emergencias, con una incidencia del 1 al 3%. A menudo está asociado a lesiones potencialmente mortales, por esta razón, es fundamental conocer los principios de diagnóstico y tratamiento, así como los protocolos de atención inicial de los pacientes politraumatizados. Método: Reportamos el caso de un paciente masculino de 47 años con trauma anorrectal contuso con compromiso del esfínter anal interno y externo, tratado con reparación primaria del complejo esfinteriano con técnica de overlapping, rafia de la mucosa, submucosa y muscular del recto. A los 12 meses presenta buena evolución sin incontinencia anal. Conclusión: El tratamiento del trauma rectal, basado en el dogma de las 4 D (desbridamiento, derivación fecal, drenaje presacro, lavado distal) fue exitoso. La técnica de overlapping para la lesión esfinteriana fue simple y efectiva para la reconstrucción anatómica y funcional. (AU)

Introduction: Anorectal trauma is a rare cause of consultation to the Emergency Department, with an incidence of 1 to 3%. It is often associated with life-threatening injuries, so it is essential to know the principles of diagnosis and treatment, as well as the initial care protocols for the polytrau-matized patient. Methods: We present the case of a 47-year-old man with a blunt anorectal trauma involving the internal and external anal sphincter, treated with primary overlapping repair of the sphincter complex and suturing of the rectal wall. At 12 months the patient presents good outcome, without anal incontinence. Conclusion: The treatment of rectal trauma, based on the 4 D ́s dogma (debridement, fecal diversion, presacral drainage, distal rectal washout lavage) was successful. Repair of the overlapping sphincter injury was simple and effective for anatomical and functional reconstruction. (AU)

RESUMO

Introduction: After the diagnosis of neoplasm of the middle and distal rectum, patients are often submitted to oncological treatment by neoadjuvant therapy. At the end of this treatment, those patients who show complete clinical response can choose, together with their physician, to adopt the watch-and-wait strategy; although it implies lower morbidity for the patient, this strategy is dependent on strict adherence to treatment follow-up for the early identification of any future local injury. Materials and Methods: Survey of data from medical records and description, and discussion of case reports with a literature review in books and databases. Results: We report the case of a 73-year-old patient diagnosed with moderately differentiated adenocarcinoma of the middle rectum, Stage II (cT3bN0M0), who presented complete clinical response after undergoing treatment with neoadjuvant therapy. Together with the assistant team, the watch-and-wait strategy was chosen. During the follow-up, an endoscopic examination showed a vegetating at the proximal limit of the tumor scar. We chose to perform submucosal endoscopic dissection. The report of the anatomopathological examination evidenced a serrated adenoma with narrow margins free of neoplasia. Conclusion: Patient adherence to cancer treatment using the watch-and-wait strategy is essential for the early identification of new local lesions. After resection of the lesion identified in the tumor scar site as a neoplasm-free lesion, it is consistent to think that this lesion would be the origin of the neoplasm, given the adenomatous origin.

RESUMO

Rectal trauma is uncommon, but it is usually associated with injuries in adjacent pelvic or abdominal organs. Recent studies have changed the paradigm behind military rectal trauma management, showing better morbidity and mortality. However, damage control techniques in rectal trauma remain controversial. This article aims to present an algorithm for the treatment of rectal trauma in a patient with hemodynamic instability, according to damage control surgery principles. We propose to manage intraperitoneal rectal injuries in the same way as colon injuries. The treatment of extraperitoneal rectum injuries will depend on the percentage of the circumference involved. For injuries involving more than 25% of the circumference, a colostomy is indicated. While injuries involving less than 25% of the circumference can be managed through a conservative approach or primary repair. In rectal trauma, knowing when to do or not to do it makes the difference.

El trauma de recto es poco frecuente, pero generalmente se asocia a lesiones de órganos adyacentes en la región pélvica y abdominal. Estudios recientes han cambiado los paradigmas del manejo tradicional derivados del trauma militar, mostrando mejores resultados en la morbilidad y mortalidad. Sin embargo, las técnicas de control de daños en el trauma rectal aún son controvertidas. El objetivo de este articulo es proponer el algoritmo de manejo del paciente con trauma rectal e inestabilidad hemodinámica, según los principios de la cirugía de control de daños. Se propone que las lesiones del recto en su porción intraperitoneal sean manejadas de la misma manera que las lesiones del colon. Mientras que el manejo de las lesiones extraperitoneales del recto dependerá del compromiso de la circunferencia rectal. Si es mayor del 25% se recomienda realizar una colostomía. Si es menor, se propone optar por el manejo conservador o el reparo primario. Saber que hacer o que no hacer en el trauma de recto marca la diferencia.

RESUMO

Resumen Introducción: El cuerpo extraño rectal (CER) es un problema de difícil manejo para el cirujano general. La vía anal es la puerta de entrada más habitual seguido de la oral. La sospecha clínica es fundamental para el diagnóstico, pudiendo apoyarse de imágenes. El tratamiento es su extracción por vía transanal o por vía anterior. Objetivos: Caracterizar, describir y presentar el tratamiento de los pacientes con CER que consultaron en urgencia del Hospital el Pino (HEP) entre los años 2011 y 2016. Material y Método: Estudio serie de casos. Se realiza revisión de fichas clínicas de pacientes con CER en un periodo de 5 años en el Servicio de Urgencia del HEP. Se identificó a los pacientes tratados en box y a aquellos tratados en pabellón. Se caracterizó según variables demográficas, tratamiento, complicaciones y días de hospitalización. Resultados: Se identificaron 18 pacientes, 13 hombres y 5 mujeres de 45 años (± 36-51) y 34 años (± 23-64) respectivamente. En 1 de ellos fue posible extracción manual transanal en box sin anestesia y en 17 se requirió tratamiento en pabellón, donde 12 fue por vía transanal y 5 por abordaje abdominal. En ningún caso se identificó lesión intestinal. Evolución postoperatoria adecuada. Días de hospitalización promedio 1,8 días. Conclusión: Este es un problema infrecuente y de difícil manejo. Existe mayor frecuencia en hombres de edades media siendo la puerta de entrada la vía anal en todos los casos. En la mayoría se requirió extracción en pabellón bajo anestesia siendo el abordaje transanal el más utilizado y con buenos resultados.

Introduction: The rectal forcing body (RFB) is a problem which involves a difficult management for surgeons. Anal via is the most frequent entrance area, followed by the oral via. Clinical suspicion is fundamental for diagnosis and it is possible to support it using imaging. Treatment considers extraction through transanal or frontal via. Aim: To describe and present the treatment of patients with rectal foreing body in the Urgency Service of El Pino Hospital during years 2011 to 2016. Materials and Method: Case studies. Clinical records revision of patients with rectal foreing body in the Urgency Service of El Pino Hospital considering a 5-year period. Patients are identified as those treated in the box and in a surgical pavilion. Patients were classified according to demographic variables, received treatment, associated complications and hospitalization time. Results: 18 patients are identified, 13 men and 5 women, 45 (± 36-51) and 34 (± 23-64) years respectively. It was possible to manually extract via trans-anal at box, in one of these cases; 17 of them required treatment at surgical pavilion, where 12 were via trans-anal and 5 via abdominal. None of these cases had intestinal injury. Post-surgery evolution was adequate. Average hospitalization was 1.8 days. Conclusion: RFB is a non-frequent problem which requires high diagnose suspicious to be able to carry out proper treatments. It is more frequent in middle age men, with transanal input. In most cases, the extraction was done in surgical pavilion and required anesthesia and were done via trans anal with good results.

RESUMO

RESUMEN Introducción: El trauma de abdomen tiene alta incidencia y con frecuencia afecta el colon y el recto, se aboga por el tratamiento mediante sutura primaria. Objetivo: Identificar diferencias en las características clínico-quirúrgicas y resultados terapéuticos de pacientes con lesiones traumáticas de colon y recto, tratados con sutura primaria y técnicas derivativas. Método: Se realizó un estudio multicéntrico descriptivo ambispectivo para determinar características clínico-quirúrgicas y resultados terapéuticos en pacientes con lesiones traumáticas de colon y recto en los hospitales Carlos J. Finlay, Joaquín Albarrán, Calixto García y Enrique Cabrera de La Habana, en el periodo 2010-2015. El universo estuvo conformado por todos los pacientes intervenidos quirúrgicamente por trauma de colon y/o recto. Resultados: La colostomía fue el proceder más frecuente (53,1 por ciento). Los pacientes en edades medias de la vida (promedio: 43,5 años), sexo masculino (71,4 por ciento), evolución hasta el tratamiento quirúrgico menor de 12 horas (73,4 por ciento); causadas por empalamientos y otros (49 por ciento) y heridas con arma blanca (38,8 por ciento). La magnitud del daño de colon y recto fue baja, con mayor afectación de colon izquierdo. La frecuencia de complicaciones graves y mortalidad fue alta en la colostomía. Conclusiones: La sutura primaria muestra mejores resultados terapéuticos y debe ser la técnica de elección en las lesiones traumáticas de colon y recto intraperitoneal(AU)

ABSTRACT Introduction: Abdominal trauma presents high incidence and often affects the colon and rectum; primary suture is the preferred treatment. Objective: To identify differences between the clinical-surgical characteristics and the therapeutic outcomes in patients with traumatic lesions of the colon and rectum, treated with primary suture and derivative techniques. Method: A multicentric, descriptive and ambispective study was carried out to determine the clinical-surgical characteristics and the therapeutic outcomes in patients with traumatic colon and rectal lesions in Carlos J. Finlay, Joaquín Albarrán, Calixto García and Enrique Cabrera Hospitals in Havana, in the period from 2010 to 2015. The study population was made up of all patients surgically intervened for colon and/or rectal trauma. Results: The colostomy was the most frequent procedure (53.1 percent). Patients in middle ages of life (average: 43.5 years), male sex (71.4 percent), evolution to surgical treatment under 12 hours (73.4 percent); caused by impalement and others (49 percent) and cutting wounds (38.8 percent). The magnitude of colon and rectum damage was low, with greater involvement of the left colon. The frequency of serious complications and mortality was high in the colostomy. Conclusions: Primary suture shows better therapeutic results and should be the technique of choice in traumatic lesions of the intraperitoneal colon and rectum(AU)

RESUMO

Introducción: El trauma de abdomen tiene una incidencia que varía según las publicaciones, pero el colon y el recto son estructuras anatómicas generalmente comprometidas. Objetivo: Determinar las características clínico-quirúrgicas y los resultados terapéuticos en pacientes con lesiones traumáticas de colon y recto tratados con técnicas derivativas. Método: Se realizó un estudio descriptivo, retrospectivo y multicéntrico en hospitales clínico-quirúrgicos seleccionados de La Habana, desde 2010 hasta 2015. El universo estuvo conformado por todos los pacientes ingresados en las instituciones con trauma rectocolónico único o múltiple tratados quirúrgicamente por colostomía. Resultados: Los pacientes estudiados se caracterizaron por edades: jóvenes (menos de 30), sexo masculino (69,2 por ciento), evolución hasta el tratamiento quirúrgico mayor de 12 horas (46,2 por ciento); causadas por empalamientos y otros (53,8 por ciento) y heridas con arma blanca (23,1 por ciento). Se aplicaron principalmente las técnicas quirúrgicas de colostomía en asa y de Hartman. Tanto el tiempo quirúrgico como la estadía fueron prolongados. La frecuencia de complicaciones graves y la mortalidad fue alta. Los costos fueron elevados. Conclusiones: La colostomía aun es una alternativa quirúrgica viable, pero su selección debe estar basada en la evaluación individualizada de los casos y en los índices pronósticos(AU)

Introduction: Abdominal trauma has an incidence that varies, according to publications; but the colon and the rectum are generally compromised anatomical structures. Objective: To determine the clinical-surgical characteristics and the therapeutic results in patients with traumatic lesions of the colon and the rectum treated with derivative techniques. Method: A descriptive, retrospective and multicenter study was conducted in selected clinical-surgical hospitals in Havana, from 2010 to 2015. The total sample consisted of all patients admitted with single or multiple rectocolonic trauma and treated with colostomy. Results: The patients studied were characterized by age: young (less than 30), male (69.2 percent), evolution until surgical treatment over 12 hours (46.2 percent); caused by impalements and others (53.8 percent) and stab wounds (23.1 percent). The surgical techniques of loop colostomy and Hartman colostomy were applied, mainly. Both surgical time and stay were prolonged. The frequency of serious complications and mortality was high. The costs were high. Conclusions: Colostomy is still a viable surgical alternative, but its selection must be based on the individualized evaluation of the cases and the prognostic rates(AU)

RESUMO

Introducción: en la vida civil la tendencia actual en el tratamiento de las lesiones traumáticas de colon y recto es hacia el cierre primario, pero aún no existe consenso. Objetivo: identificar características y evolución de 36 pacientes con traumatismos de colon a los que se les practicó sutura primaria. Métodos: estudio descriptivo, de cohorte retrospectiva. Se estudiaron pacientes atendidos en hospitales docentes de la provincia de La Habana, desde noviembre de 2008 hasta enero de 2012, así como los factores relacionados con la ocurrencia de complicaciones y los costos. Los datos fueron tomados de la historia clínica y del informe operatorio, en cada hospital. La información fue procesada de forma automatizada (SPSS 15.0). Se utilizó análisis de distribución de frecuencias, y el test de homogeneidad para identificar las variables relacionadas con la ocurrencia de complicaciones. Resultados: la causa más frecuente de las lesiones fue el arma blanca (86,1 por ciento). Los factores relacionados con la ocurrencia de complicaciones fueron el agente causal y la severidad de las lesiones según la escala de Flint (p= 0,02 y p= 0,04). Los costos promedio por tiempo quirúrgico y estadía resultaron ser de: $ 1091,88 y $ 1250,82. Conclusiones: las principales complicaciones por empleo de sutura primaria en los hospitales docentes de La Habana fueron: infección del sitio quirúrgico y sangramiento postoperatorio, y los factores relacionados con ellas: el agente causal y la severidad de las lesiones. El empleo de la sutura primaria es una opción terapéutica que parece razonable y menos costosa que la colostomía(AU)

Introduction: In civilian life, the current trend in the treatment of colon and rectum traumatic lesions is for the primary closure, but there is still no consensus. Objective: to identify the characteristics and outcome of 36 patients with colon trauma colonist who underwent primary suture. Methods: A descriptive study of retrospective cohort was carried out; we studied patients treated in Havana Province teaching hospitals, from November 2008 to January 2012, as well as the factors related to the occurrence of complications and costs. Data were collected from the medical records and the operative report, in each of the hospitals. The information was processed in an automated system (SPSS 15,0). Analysis of frequency distribution and homogeneity test were used to identify variables related to the occurrence of complications. Results: The most frequent cause of injury was stab (86,1 percent). The factors related to the occurrence of complications and the severity of lesions were the causative agents, as measured by the Flint scale (p= 0,02 and p= 0,04). Average costs per surgical and stay time turned out to be: $ 1091,88 and $ 1250,82. Conclusions: The main complications from the use of primary suture in teaching hospitals of Havana are: surgical site infection and postoperative bleeding, and other factors related to them: the causative agent and the severity of lesions. The use of primary suture is a therapeutic option that seems to be reasonable and less expensive than the colostomy(AU)

RESUMO

Fecal management systems are widely used to prevent complications of fecal incontinence such as skin breakdown and pressure ulcers. However they are occasionally associated with complications such as bleeding and pressure necrosis of rectal mucosa. We present a patient with Clostridium difficile colitis with a prolonged hospital stay requiring the use of Flexi-Seal Fecal Management System who developed abdominal pain and distention with obstipation. Computed tomography of abdomen showed dilatation of small and large bowel loops with a transition point at rectosigmoid junction. Flexible sigmoidoscopy revealed the presence of a severe stricture at the rectosigmoid junction that was not amenable to endoscopic dilation. Surgical resection with an end-colostomy was performed to relieve the obstruction. To the best of our knowledge, this is the first reported case of a high-grade stricture due to use of bowel management system that needed bowel resection surgery. (AU)

Sistemas de manejo fecal são amplamente utilizados com o objetivo de evitar as complicações da incontinência fecal, além de avarias à pele e úlceras de decúbito. No entanto, ocasionalmente esses sistemas estão associados a complicações, como sangra- mento e necrose por pressão da mucosa retal. Apresentamos um paciente com colite por Clostridium difficile com prolongada permanência no hospital e que necessitou do uso doFlexi-Seal Fecal Management System; esse paciente veio a sofrer dores e distensão abdominal, juntamente com obstipação. A tomografia computadorizada do abdome revelou dilatação de alças de intestine delgado e grosso, com um ponto de transição na junção retossigmóidea. A sigmoidoscopia flexível revelou presença de grande constrição na junção retossigmóidea, que não permitia dilatação endoscópica. Realizamos ressecção cirúrgica com colostomia terminal, com o objetivo de aliviar a obstrução. Até onde vai nosso conhecimento, este é o primeiro caso relatado de constrição de alto grau causada pelo uso de um sistema de manejo intestinal necessitando de cirurgia de ressecção intestinal. (AU)

RESUMO

Background: Rectal prolapse is the protrusion of one or more layers of the rectum through the anal sphincter. Some of the possible causes are tenesmus, endoparasitism and large bowel inflammation. Natural orifice transluminal endoscopic surgery (NOTES) consists of advanced techniques to gain access to body cavities through natural openings without skin incision. Different access routes may be used. However, transrectal NOTES has not been often reported. This paper reports a case of rectal prolapse after transrectal NOTES in a porcine model. Case: A healthy, female domestic swine underwent experimental peritoneoscopy through transrectal route. The animal weighed 20 kg and was approximately 90 days old. Under general anesthesia, a pneumoperitoneum was created and, after this, the rectal lining was pulled out and incised so that the endoscope could be introduced into the abdominal cavity. Subsequently, the cavity was deflated and the rectal wall was sutured under direct viewing with single-layer extramucosal sutures closed with 3-0 polyglactin 910 and simple continuous pattern in the muscular region and submucosa. There was edema of the rectal lining with a slight protrusion and was reduced manually. There was prolapse recurrence and a pursestring suture was placed around the anus. The suture ruptured about 72 h after the endoscopic procedure and self-mutilation of the perineal...(AU)
