Evisceración vaginal espontánea en paciente con antecedente de histerectomía: reporte de caso y revisión de la literatura / Spontaneous vaginal evisceration in woman with prior pelvic surgery: case report and literature review

Reportar un caso de evisceración vaginal espontánea en paciente con antecedentes quirúrgicos de histerectomía vaginal y hacer una revisión de la literatura sobre los principales factores de riesgo asociados a la presentación de este evento. Se presenta el caso de una paciente de 74 años multípara de 12 partos vaginales con antecedente ginecológico de histerectomía vaginal en 2012, en el año 2014 una sacroespinocolpopexia con colocación de cinta transobturadora más colporrafia anterior, en 2018 presenta cuadro con asas intestinales protruyendo con signos de isquemia a través de defecto en cúpula vaginal, se realiza resección de intestino delgado y anastomosis termino-terminal, con posterior cierre de defecto por vía abdominal. Se realizó una búsqueda en las bases de datos PubMed, Scielo, Google Scholar y Science Direct para artículos publicados en inglés y español, de los últimos 22 años. Se identificaron 16 títulos que cumplieron con los criterios de selección, los resultados de la revisión muestran factores de riesgo comunes. La evisceración vaginal por dehiscencia de la cúpula vaginal es una patología poco prevalente, el abordaje mínimamente invasivo, que ha aumentado en los últimos años, ha conllevado un aumento de la incidencia, siendo la histerectomía por laparoscopia el de mayor riesgo.

To report a case of spontaneous vaginal evisceration in a patient with a surgical history of vaginal hysterectomy, and to review the literature on the main risk factors associated with the presentation of this event. We present the case of a 74-year-old multiparous patient with 12 vaginal deliveries with a gynecological history of vaginal hysterectomy in 2012, in 2014 a sacrospinocolpopexy with placement of transobturator tape plus anterior colporrhaphy, in 2018 she presented with intestinal loops protruding with signs of ischemia through a defect in the vaginal vault, resection of the small intestine and end-to-end anastomosis were performed, with subsequent closure of the defect through the abdomen. A search was made in the PubMed, Scielo, Google Scholar and Science Direct databases for articles published in English and Spanish, from the last 22 years. 16 titles that met the selection criteria were identified; the results of the review show common risk factors. Vaginal evisceration due to dehiscence of the vaginal vault is a rare pathology, the minimally invasive approach, which has increased in recent years, has led to an increase in incidence, with laparoscopic hysterectomy being of greater risk.

Resección intestinal por endometriosis severa, diagnóstico y tratamiento luego de la introducción de la Unidad de Endometriosis: revisión de 18 años en el Hospital Clínico de la Universidad de Chile / Bowel resection for severe endometriosis, diagnosis and treatment after the introduction of Endometriosis Unit: 18 years review, Clinical Hospital of the University of Chile

INTRODUCCIÓN: La endometriosis intestinal afecta en gran medida la calidad de vida de una mujer joven y habitualmente requiere un tratamiento quirúrgico con resección intestinal. Esta cirugía es técnicamente compleja por las adherencias firmes del intestino a la vagina, el útero y los ovarios. OBJETIVO: Describir y analizar los resultados quirúrgicos e histopatológicos de las resecciones intestinales por endometriosis grave durante los últimos 18 años en el Hospital Clínico de la Universidad de Chile, en relación con la introducción de la unidad multidisciplinaria de endometriosis, a partir del año 2011, y las experiencias publicadas en la literatura chilena y extranjera. MÉTODO: Trabajo retrospectivo realizado en un hospital terciario desde el año 2001 hasta el año 2019. Las pacientes se asignaron a dos grupos según el período de cirugía: grupo 2001-2010 y grupo 2011-2019, luego de la introducción de la unidad de endometriosis. Se recopilaron todas las pacientes a las que se realizó una resección intestinal (discoidal o segmentaria) por endometriosis, por laparotomía o laparoscopía. Los datos distribuidos normalmente se presentan como promedio ± DE y los datos no paramétricos como mediana (rango). Las comparaciones demográficas de variables continuas se hicieron con la prueba t de Student y las de las variables categóricas con las pruebas de ji al cuadrado o de Fisher. La significación estadística se estableció en p < 0,05. RESULTADOS: Se recopilaron 52 casos. El 94,2% de las cirugías fueron electivas. El 5,8% fueron de urgencia por obstrucción intestinal (todas entre 2001 y 2010). Un 75% de las cirugías fueron laparoscópicas. Se realizó resección segmentaria en el 67,3%, resección discoidal simple en el 28,8%, resección discoidal doble en el 1,9% y resección segmentaria y una discoidal en el 1,9%. La histopatología demostró compromiso de la lesión hasta la mucosa intestinal en un 7,7%. Hubo franca disminución del dolor en el seguimiento de las pacientes. El 24% de las pacientes con deseo de embarazo y endometriosis intestinal lograron un parto de término mediante fecundación in vitro o espontáneamente. Hubo cuatro complicaciones posoperatorias, tres de ellas de categoría II según la clasificación de Clavien-Dindo y una de categoría IV A con reintervención a las 72 horas. Al comparar ambos periodos, en 2001-2010 los exámenes diagnósticos utilizados fueron ecografía transvaginal (0%), enema baritado (60%), tomografía computarizada de abdomen y pelvis (45%) y resonancia magnética pelviana (20%), mientras que en 2011-2019 fueron ecografía transvaginal (100%), enema baritado (3%), tomografía computarizada (3%) y resonancia magnética pelviana (66%). En 2001-2010, las lesiones fueron más más infiltrativas (mayor compromiso mucoso y submucoso) (75 vs. 16% de las resecciones intestinales; p < 0,05), estenóticas (cirugías de urgencia por obstrucción), con mayor porcentaje de resecciones segmentarias (100 vs. 46,9%; p < 0,05) y más días de hospitalización (5,8 ± 2,3 vs. 4,1 ± 0,9 días) que en 2011-2019. CONCLUSIONES: A nuestro entender, esta es la serie más grande publicada en Chile de resecciones intestinales por endometriosis. Estos hallazgos demuestran cómo la introducción de la unidad multidisciplinaria de endometriosis permite un diagnóstico precoz y un tratamiento quirúrgico eficaz y oportuno, tal como se decribe en la literatura.

INTRODUCTION: Bowel endometriosis severely affects a young woman's quality of life and often requires surgical treatment with bowel resection. This surgery is technically complex due to the tight adhesions of the intestine to the vagina, uterus, and ovaries. The objective of this work is to describe and analyze the surgical and histopathological results of intestinal resections for severe endometriosis during the last 18 years at the Clinical Hospital University of Chile, in relation to the implementation of the multidisciplinary endometriosis unit, based on the year 2011 and the experiences published in Chilean and foreign literature. METHOD: Retrospective work carried out in a tertiary hospital from 2001 to 2019. The patients were assigned to two groups according to the surgery period: group 2001-2010 and group 2011-2019, after endometriosis unit formation. All patients who underwent bowel resection (discoidal or segmental) for endometriosis by laparotomy or laparoscopy were collected. Normally distributed data are presented as mean ± SD and nonparametric data as median (range). Demographic comparisons of continuous variables are compared using Student's t test and categorical variables using chi squared or Fisher's test. Statistical significance was established at p < 0.05. RESULTS: 52 cases were collected. 94.2% of the surgeries were elective. 5.8% were urgent due to intestinal obstruction (all between 2001 and 2010). 75% of the surgeries were laparoscopic. Segmental resection 67.3%, simple discoidal resection 28.8%, double discoidal resection 1.9% and segmental resection and a discoidal resection 1.9%. Histopathology showed involvement of the lesion up to the intestinal mucosa in 7.7%. A marked decrease in pain in the follow-up of the patients. 24% of the patients with a desire for pregnancy and intestinal endometriosis achieved a full-term delivery by IVF or spontaneously. There were four postoperative complications, three of them category II according to the Clavien-Dindo classification, and one category IV A complication with reoperation at 72 h. When comparing both periods, between 2001-2010 the diagnostic tests used were: transvaginal ultrasound (ECO TV) (0%), barium enema (BE) (60%), abdomen pelvis CT (45%) and pelvic resonance (MRI) (20%). Between 2011 and 2019 ECO TV (100%), EB (3%), TAC (3%) RM (66%). In the period 2001 to 2010, the lesions were more infiltrative (greater mucosal and submucosal involvement) (75% vs 16% of intestinal resections (P <0.05)), stenotic (urgent surgery for obstruction), with a higher percentage of resections segmental (100% vs 46.9% (P <0.05) and more days of hospitalization (5.8 ± 2.3 SD vs 4.1 ± 0.9 SD) than in the period from 2011 to 2019. CONCLUSIONS: To our knowledge, this is the largest series published in Chile of intestinal resections for endometriosis. These findings demonstrate how the introduction of the multidisciplinary endometriosis unit allows early diagnosis and effective and timely surgical treatment as described in the literature.

Cirugía colorrectal en tiempos de COVID-19: guías de recomendación del Hospital Británico de Buenos Aires / Colorectal surgery in times of COVID-19: recommendation guides of the British Hospital of Buenos Aires

Se trató de redactar una guía para la práctica segura de la especialidad en tiempos de COVID-19. Se realizó una búsqueda de las publicaciones recientes disponibles en Pub-Med y en otros buscadores, se utilizó la experiencia de expertos a través de diferentes conferencias o comunicados de sociedades científicas. Esta pandemia nos ha obligado a aprender de una manera vertiginosa el manejo de una nueva enfermedad, donde especialistas en cirugía comenzamos a hablar de terminología clínica, virológica, entre otras completamente nueva y desconocida para la mayoría de nosotros. Tuvimos que adaptar nuestra práctica habitual a nuevos estándares, cometiendo diferentes errores en el manejo inicial, provocados por la falta de información previa. La guía trata de abarcar los tópicos considerados más relevantes en este momento, como son el manejo del consultorio, recomendaciones de que patologías se recomienda operar y cuáles no. Recomendaciones de tratamientos alternativos al quirúrgico mientras dura la pandemia. Métodos de diagnósticos utilizados para evaluar infección en pacientes que se someterán a una cirugía, etc. Se agregaron links y apéndices para aquellos que deseen ampliar algún tema en particular, esto evita que la guía sea más extensa y pierda su practicidad con la que fue pensada. Esperamos esta guía sirva para facilitar la compresión de esta nueva enfermedad y su manejo para cualquier cirujano que necesite asistir a pacientes con patología colorrectal. Seguramente al finalizar estas líneas habrá nueva evidencia que deberá ser adaptada e incorporada a la presentada actualmente.

An attempt was made to write a guide for the safe practice of the specialty in times of COVID-19. A search of recent publication available in Pub-Med and other platforms was performed. Experts' opinions and experiences were taken into account from various conferences or communications of scientific societies. This pandemic has forced us to learn the management of a new disease in a sudden way. Surgical specialists began to learn clinical and virologic terminology, among other new concepts previously ignored by most of us. We were forced to adapt our usual practice to new standards, making different mistakes in the initial handling, caused by the lack of prior information.The present guide tries to cover the topics considered most relevant at this time, such as outpatients ́ management, recommendations of which patients we should operate on and which procedures should be postponed. Recommendations for alternative treatments to surgery while the pandemic lasts. Diagnostic methods used to assess infection in patients who will undergo surgery, etc. Links and appendices have been added for those who wish to expand on a particular topic, this prevents the guide from being too extensive and losing the practicality with which it was intended. We hope this guide will facilitate the understanding of this new disease and its management for any surgeon who needs to assist patients with colorectal pathology. By the time we would have finished these lines there will be new evidence that must be adapted and incorporated into those currently presented.

Manejo quirúrgico de la endometriosis colorrectal: monografía destacada del curso de la SACP 2019 / Surgical Management of Colorectal Endometriosis: featured monograph from the 2019 SACP Course

La endometriosis es una de las patologías ginecológicas benignas más frecuente, ocurre en un 7-10% de las mujeres en edad reproductiva y es causal de dolores crónicos e infertilidad. Se trata de una población joven y sana por lo demás. La sospecha diagnóstica de esta entidad debe ser alta y su manejo multidisciplinario.La endometriosis colorrectal representa una variable altamente incapacitante y es aquí donde se plantea la necesidad de un tratamiento más agresivo para su resolución. Frente a esto nos preguntamos, ¿qué rol tiene la cirugía?, ¿cuáles serían sus ventajas y desventajas?, ¿por qué deberíamos elegirla como método terapéutico?.La presente monografía fue inspirada en todas las pacientes que nos plantearon esta controversia. Que motivaron interconsultas, ateneos, búsqueda de bibliografía. Que generaron discusiones, dudas e incertidumbres y nos hicieron salir del rol de cirujanos al que estamos habituados y nos enseñaron a acompañar, cuando no pudimos curar

Surgical treatment of intestinal endometriosis: outcomes of three different techniques / Tratamento cirúrgico de endometriose intestinal: resultados de três técnicas operatórias

Abstract Objective To outline the demographic and clinical characteristics of patients with deep intestinal endometriosis submitted to surgical treatment at a tertiary referral center with a multidisciplinary team, and correlate those characteristics with the surgical procedures performed and operative complications. Methods A prospective cohort from February 2012 to November 2016 of 32 women with deep intestinal endometriosis operations. The variables analyzed were: age; obesity; preoperative symptoms (dysmenorrhea, dyspareunia, acyclic pain, dyschezia, infertility, urinary symptoms, constipation and intestinal bleeding); previous surgery for endometriosis; Enzian classification; size of the intestinal lesion; and surgical complications. Results Themean age was 37.75 (±5.72) years. A total of 7 patients (22%) had a prior history of endometriosis. The mean of the largest diameter of the intestinal lesions identified intraoperatively was of 28.12 mm (±14.29 mm). In the Enzian classification, there was a predominance of lesions of the rectum and sigmoid, comprising 30 cases (94%). There were no statistically significant associations between the predictor variables and the outcome complications, even after the multiple logistic regression analysis. Regarding the size of the lesion, there was also no significant correlation with the outcome complications (p = 0.18; 95% confidence interval [95%CI]:0.94-1.44); however, there was a positive association between grade 3 of the Enzia classification and the more extensive surgical techniques: segmental intestinal resection and rectosigmoidectomy, with a prevalence risk of 4.4 (p < 0.001; 95%CI:1.60-12.09). Conclusion The studied sample consisted of highly symptomatic women. A high prevalence of deep infiltrative endometriosis lesions was found located in the rectum and sigmoid region, and their size correlated directly with the extent of the surgical resection performed.

Resumo Objetivo Delinear as características das pacientes portadoras de endometriose profunda intestinal submetidas a tratamento cirúrgico em centro de referência com equipe multidisciplinar, e correlacionar tais achados com a extensão de doença e com os procedimentos cirúrgicos realizados. Métodos Tratamento cirúrgico no período de fevereiro de 2012 a novembro de 2016 em 32 mulheres portadoras de endometriose profunda intestinal. Variáveis analisadas: idade; obesidade; queixas pré-operatórias: dismenorreia, dispareunia, dor acíclica, disquezia, sangramento uterino anormal, infertilidade, sintomas urinários, constipação, e sangramento intestinal; cirurgia prévia para tratamento de endometriose profunda; classificação de Enzian; técnica cirúrgica aplicada; tamanho da lesão intestinal; e complicações operatórias. Resultados A média de idade foi de 37,75 (±5,72) anos. Um total de 7 (22%) pacientes tinha histórico de abordagem prévia da endometriose. A média do maior diâmetro das lesões intestinais foi de 28,12 mm (±14,29 mm). Na classificação de Enzian, houve predomínio das lesões da região de reto ou retossigmoide no compartimento posterior, num total de 30 casos (94%). Não foi observada associação estatística significativa entre as variáveis preditivas e o desfecho da complicação, mesmo após análise de regressão logística múltipla. Quanto ao tamanho da lesão, também não houve correlação significativa com o desfecho complicação (p = 0,18; intervalo de confiança de 95% [IC95%]: 0,94-1,44). No entanto, Houve associação positiva entre o grau 3 da classificação de Enzian e a técnica cirúrgicamais extensa: ressecção intestinal segmentar e retossigmoidectomia, com risco de prevalência de 4,4 (p = 0,00003; IC95%: 1,60-12,09). Conclusão A amostra populacional estudada foi constituída de mulheres muito sintomáticas. Foi encontrada prevalência alta de lesões de endometriose infiltrativa profunda localizadas em região de retossigmoide, e seu tamanho correlacionou-se diretamente com a extensão da ressecção cirúrgica realizada.

Escalas de predicción en el pronóstico del paciente con hemorragia digestiva alta no varicosa / Predicting scales for prognosis of patients with non-variceal upper gastrointestinal bleeding

La hemorragia digestiva alta no varicosa constituye una importante causa de morbilidad y mortalidad en el mundo. Para su manejo se ha impuesto la necesidad de usar escalas pronósticas para definir la conducta a seguir con un empleo óptimo de los recursos médicos, de manera tal que se garantice una asistencia de calidad al paciente. El objetivo del trabajo es realizar un resumen de los aspectos positivos y negativos de las escalas, relacionar los parámetros que contemplan y las posibilidades de su aplicación en Cuba. Se efectuó una búsqueda en los registros bibliográficos existentes de las bases de datos de PUBMED y EBSCO. Se utilizaron las palabras claves, en idiomas español e inglés: hemorragia digestiva alta no varicosa y escalas pronósticas. Se realizó una revisión de los diferentes modelos; se relacionaron a los autores principales de las escalas; se dividieron en preendoscópicas y endoscópicas y se caracterizaron las más utilizadas. La información recogida permitió obtener una visión general, al mostrar las diferentes variantes existentes y clasificar al paciente según el riesgo que presenta, de acuerdo con los índices pronósticos obtenidos después de la aplicación de la escala. Se concluye que las escalas pronósticas permiten evaluar la necesidad de intervención urgente, la probabilidad de sangrado, la necesidad de cirugía o la mortalidad aguda en la toma de decisiones médicas y su uso está en correspondencia con las particularidades de cada contexto.

The non-variceal upper gastrointestinal bleeding is a major cause of morbidity and mortality worldwide. The need for prognostic scales to define the course of action regarding the optimal use of medical resources has imposed, so that patient care quality is guaranteed. The aim of this paper is to go over the positive and negative aspects of the scales, to relate the parameters included and the possibilities of its application in Cuba. A search was conducted on existing bibliographic records in PubMed and EBSCO databases. Keywords in Spanish and English were used, such as non-variceal upper gastrointestinal bleeding, and prognostic scales. A review of different models was performed; the principal authors of the scales were related; scales were divided into pre-endoscopic and endoscopic and the most used were characterized. The information collected allowed for an overview, showing the various existing variants and classify patients according to risks, according to forecasts indices obtained after the scale application. It is concluded that the prognostic scales to assess the need for urgent intervention, the bleeding likelihood, surgery or acute mortality in medical decision making and their use is in line with each context particularities.

A Rare Case of Bowel Gangrene in Pregnancy : A Surgical and Obstetric Catastrophe.

An unusual case of bowel gangrene involving jejunum upto the middescending colon leading to septicaemic shock, presented as a case of placental abruption with IUD with shock. Case Report : The 25 year old primigravida patient with 34 weeks of gestation was referred from peripheral obstetrician to SVNGMC, in a state of shock with clinical features suggestive of concealed type of placental abruption with IUD. In view of placental abruption with shock, emergency caesarean section was performed. Per Operative Findings: Foul smelling peritoneal fluid, IUD. Baby with placental separation with RP clot and gangrenous bowel from jejunum to middescending colon. As such long segment of bowel was involved; surgeon decided resection and end to end anastomosis was not possible. Propable diagnosis like superior mesenteric artery thrombosis/ Embolism was made. pt was put on low dose inj. Heparin and later managed in Surgical I.C.U. & succumbed on day 3 postop. Conclusion: Hypercoagulable state normally found in pregnant women which is believed to result in superior mesenteric vessel thrombosis and then intestinal ischaemia. It is extremely important not to miss any complaint like pain in abdomen and other G.I. complaints that may have any surgical or medical pathology associated with pregnancy.

Tratamiento laparoscópico resectivo por endometriosis severa con compromiso colorrectal: factibilidad y seguridad / Laparoscopic resective treatment for severe endometriosis with colorectal involvement: feasibility and safety

Introducción: La endometriosis intestinal es una forma severa de esta entidad, afectando hasta un 12% de estas pacientes. Su tratamiento quirúrgico resulta difícil debido a la distorsión anatómica que genera, más aún cuando el abordaje es el laparoscópico. Objetivo: Analizar la factibilidad y seguridad terapéutica de las resecciones colorrectales laparoscópicas por endometriosis severa. Diseño: Observacional retrospectivo de una base de datos prospectiva. Material y métodos: Pacientes operadas con diagnóstico de endometriosis con compromiso colorrectal a las cuales se les realizó una resección intestinal entre enero de 2003 y septiembre de 2013. Resultados: De 1343 casos operados, 17 pacientes fueron intervenidas por endometriosis severa con compromiso colorrectal. Edad media 35 años (rango 23 - 47), IMC medio 22 kg/m2 (rango 18 – 35).El segmento frecuentemente afectado fue el recto (52%) y la unión rectosigmoidea (30%).En 9 pacientes se realizó una resección anterior baja, 4 de ellas requirieron ostomía derivativa; 5 pacientes recibieron una Resección anterior alta y 3 pacientes una hemicolectomía derecha. Tiempo operatorio medio 187 min (rango 60 - 360) y el sangrado operatorio medio 90cc (rango 20 - 500). Índice de conversión 11%. No se registraron complicaciones intraoperatorias. Estadía hospitalaria media 4 días (rango 2 - 10).Morbilidad global 23%.Se observaron complicaciones postoperatorias mayores en 1 caso (dehiscencia anastomótica) y menores en 3 casos (retención urinaria). No se registró readmisión hospitalaria y la mortalidad fue nula. Conclusiones: El tratamiento laparoscópico de la endometriosis intestinal severa es una opción factible y segura. En centros entrenados, puede ser adoptada como primera opción en el manejo de la endometriosis pelviana con severo compromiso colorrectal.

Background: Deep infiltrating endometriosis with bowel involvement is an aggressive form of endometriosis with an incidence up to 12%.It´s surgical management represents a challenge because of the distortion of the anatomy this entity produces, even more so when the approach is laparoscopical. The aim of this study was to evaluate the feasibility and security of colorectal laparoscopic resections for bowel endometriosis. Materials and methods: All patients presenting to the Department of Colorectal Surgery with bowel endometriosis from January 2003 to September 2013 were identified from a prospective database and retrospectively analyzed. Results: From 1343 colorectal laparoscopic procedures, 17 patients received surgery because of bowel endometriosis. Median age 35 years (range 23 to 47) and median BMI 22 kg/m2 (range 18 to 35). The most affected segments included Rectum 52% and the Rectosigmoid junction 30%. Resections included 9 low anterior resections (4 of them required fecal diversion), 5 High anterior resections and 3 Right Hemicolectomies. Median operating time was 187 minutes (range 60 to 360). Conversion rate 11%. Median length of stay was 4 days (range 2 to 10). There were none intraoperative complications. Global morbidity rate was 23%. Postoperative major complications occurred in 5.8%: one patient presented an anastomotic leak. There were 3 minor complications consistent of urinary retentions. There were no readmissions and mortality rate was nule. Conclusions: Laparoscopic surgery of bowel endometriosis is a feasible and safe therapeutic option. In trained centers, it can be adopted as the first option in the management of deep infiltrating pelvic endometriosis with bowel involvement.

Comparison of Single Layer Versus Double Layer Continuous Anastomotic Technique for Small Bowel Resection and Anastomosis.

Small intestinal resection and anastomosis is an important surgical procedure. Aims and Objectives : To study efficacy and safety of single layer intestinal anastomosis using non absorbable suture material against conventional double layer anastomosis. Single layer anastomosis will decrease surgery time and minimize incorporation of foreign body [sutures]. Materials and Methods : Present study carried out in Pravara rural hospital, Loni. It is a prospective study of 50 patients who underwent elective and emergency resection and anastomosis of small intestine from May 2004 to Oct 2006. Observations : Majority of patients were in the age group of 40-50 yrs and children. Intestinal obstruction with gangrene was the most common indication for anastomosis. Significant difference was found in recovery and complications between two methods after applying Z-test. Discussion : Forty seven patients required resection and anastomosis and 3 patients operated for ileostomy closure. Single layer anastomosis has superior results as compared to double layer anastomosis of small intestine. Conclusion : Arithmetical means of these endpoints suggest that single layer method offers same or better results than double layer method.

Tumor miofibroblástico inflamatorio (pseudotumor inflamatorio) ocasionando abdomen agudo / Inflammatory myofibroblastic tumor as a cause of acute abdomen

Background: Inflammatory myofibroblastic tumor (IMT) is a rare disease, usually benign, although with possible progression to malignancy. The clinical features depend on its location. If the resection is completed, surgery is curative, but recurrence is possible. The diagnosis is always histopathological. Case report: We report a 20 years old female admitted for a progressive abdominal pain lasting 24 hours. The patient was subjected to an appendectomy but in the postoperative period she continued with nausea and vomiting. The patient was operated again, finding a small bowel tumor with multiple adhesions, occluding the intestinal lumen and a Meckel diverticulum. The pathological study of the tumor reported the presence of an inflammatory myofibroblastic tumor. The patient had an uneventful postoperative outcome.

Introducción: El tumor miofibroblástico inflamatorio (TMI) es una enfermedad poco frecuente, en general benigna, aunque con posible evolución a malignidad. Las características clínicas dependen del lugar en el que esté ubicado. La cirugía es curativa siempre y cuando la resección sea total; aunque no se excluye la posibilidad de recidivas. El diagnóstico siempre es histopatológico. Dadas sus características clínicas y sitios de presentación se ha denominado de distintas formas e incluso sigue siendo motivo de estudio a fin de entender completamente su fisiopatología. Caso clínico: Presentamos un caso de esta rara entidad con un cuadro clínico de un abdomen agudo.

Cistadenoma mucinoso del apéndice cecal como causa de gangrena intestinal / Appendiceal mucocele causing large bowel gangrene

Introduction: Appendiceal mucocele are lesions located in the cecum, which are found in 0.2 to 0.3 percent of appendectomies and correspond to 8-10 percent of all appendiceal tumors. Clinical case: We report a 83 years old female consulting for abdominal pain lasting 24 hours. On physical examination, signs of peritoneal irritation were found. The patient was operated, finding an appendiceal tumor that was coiled up in the mesentery with large bowel gangrene. An intestinal resection, terminal ileostomy, appendectomy and surgical lavage were performed. The pathological study of the surgical piece reported a mucinous cystadenoma.

Introducción: Los tumores del Apéndice Cecal corresponden al 0,5 por ciento de las neoplasias gastrointestinales y se encuentran entre el 0,8 por ciento y el 1 por ciento de las apendicectomías. El término Mucocele Apendicular (AM), se refiere a un grupo de lesiones localizados a nivel del ciego cuyo rango de incidencia está entre el 0,2 por ciento y el 0,3 por ciento de todas las apendicectomías, y entre el 8-10 por ciento de todos los tumores apendiculares. Las presentaciones clínicas más frecuentes son: cuadro clínico de apendicitis aguda, como hallazgo incidental como en el caso de esta paciente, o como masa abdominal en fosa ilíaca derecha. Caso clínico: Se presenta un caso de Cistade-noma Mucinoso Apendicular (CAM) encontrado como hallazgo incidental en un abdomen agudo quirúrgico con la particularidad de presentarse con una necrosis intestinal.

Complicated diverticular disease: the changing paradigm for treatment / Doença diverticular complicada: alterando o padrão de tratamento

The term "complicated" diverticulitis is reserved for inflamed diverticular disease complicated by bleeding, abscess, peritonitis, fistula or bowel obstruction. Hemorrhage is best treated by angioembolization (interventional radiology). Treatment of infected diverticulitis has evolved enormously thanks to: 1) laparoscopic colonic resection followed or not (Hartmann's procedure) by restoration of intestinal continuity, 2) simple laparoscopic lavage (for peritonitis +/- resection). Diverticulitis (inflammation) may be treated with antibiotics alone, anti-inflammatory drugs, combined with bed rest and hygienic measures. Diverticular abscesses (Hinchey Grades I, II) may be initially treated by antibiotics alone and/or percutaneous drainage, depending on the size of the abscess. Generalized purulent peritonitis (Hinchey III) may be treated by the classic Hartmann procedure, or exteriorization of the perforation as a stoma, primary resection with or without anastomosis, with or without diversion, and last, simple laparoscopic lavage, usually even without drainage. Feculent peritonitis (Hinchey IV), a traditional indication for Hartmann's procedure, may also benefit from primary resection followed by anastomosis, with or without diversion, and even laparoscopic lavage. Acute obstruction (nearby inflammation, or adhesions, pseudotumoral formation, chronic strictures) and fistula are most often treated by resection, ideally laparoscopic. Minimal invasive therapeutic algorithms that, combined with less strict indications for radical surgery before a definite recurrence pattern is established, has definitely lead to fewer resections and/or stomas, reducing their attendant morbidity and mortality, improved post-interventional quality of life, and less costly therapeutic policies.

O termo diverticulite "complicada" é reservado para a doença diverticular complicada por sangramento, abscesso, peritonite, fístula ou obstrução intestinal. A hemorragia é melhor tratada por angioembolização (radiologia intervencionista). O tratamento de diverticulite infectada evoluiu enormemente graças a: 1) ressecção laparoscópica do cólon seguida ou não (procedimento de Hartmann) pelo restabelecimento de continuidade intestinal, 2) lavado laparoscópico simples (peritonite + / - ressecção). A diverticulite (inflamação) pode ser tratada somente com antibióticos, anti-inflamatórios, combinados com repouso e medidas de higiene. O abscesso diverticular (Hinchey graus I, II) pode ser inicialmente tratado somente com antibióticos e / ou drenagem percutânea, dependendo do tamanho do abcesso. A peritonite purulenta generalizada (Hinchey III) pode ser tratada pelo clássico procedimento Hartmann, pela exteriorização da perfuração, como se fosse um estoma, pela ressecção primária com ou sem anastomose, com ou sem desvio do trânsito e, por último, a simples lavagem laparoscópica, geralmente, sem drenagem. A peritonite por fezes (Hinchey IV), uma indicação para o tradicional procedimento de Hartmann, também pode se beneficiar da ressecção primária seguida de anastomose, com ou sem desvio e lavagem laparoscópica. A obstrução aguda (inflamação local, ou aderências, formação pseudotumoral, estenoses crônicas) e fístula são, na maioria das vezes, tratadas por ressecção, preferencialmente, laparoscópica. Algoritmos terapêuticos pouco invasivos combinadas com indicações menos rigorosas para a o emprego da cirurgia radical antes de um padrão definido de recorrência, estão estabelecidos, ocasionando um número menor de ressecções e / ou estomas, reduzindo a morbidade e a mortalidade, melhorando a qualidade de vida após a intervenção, e geram uma tratamento menos dispendioso.

Predictores de riesgo de mortalidad en cirugía colorrectal de urgencia / Predictors of mortality in emergency colorectal surgery

Antecedentes: La manera de evaluar los resultados de la cirugía colorrectal efectuada en condiciones de urgencia es un aspecto controvertido. La mayoría de los grupos utilizan para este análisis la medición de los índices de morbilidad y mortalidad postoperatoria. Varios sistemas de puntuación o scores son utilizados para tal fin. Los resultados obtenidos son dispares por lo cual ninguno de ellos tiene consenso para su utilización. Objetivos: Identificar los factores de riesgo que influyen en la mortalidad post operatoria en pacientes con patología colorrectal resecados en condiciones de urgencia. Evaluar estadísticamente su capacidad predictiva de mortalidad. Lugar de realización: Institución Privada Polivalente de alta complejidad. Diseño: Estudio observacional, retrospectivo, en lote de atención consecutiva. Población: Pacientes con patología colorrectal resecados en condición de urgencia. Método: Análisis uni y multivariado de trece variables. Confección de una formula para predecir óbito y validación de la misma. Resultados: El ingreso del paciente por patologia isquémica, los valores del score ASA = o > a IV y de urea = o > a 80 mg %, son factores predictores de óbito en pacientes sometidos a cirugía de urgencia por patología colorrectal. A partir de los datos del modelo predictivo final se construyó la siguiente fórmula de predicción de óbito: (1/1 + exp ­(-2.2+2.9 X1+1.8 X2+1.7 X3)). Los valores de cribaje de la fórmula de predictibilidad de óbito fueron los siguientes: Sensibilidad 37% (lC 95% 19.3-57.7%). Especificidad 94.2% (lC 95% 84-98.8%). Valor predictivo positivo 76.9% (IC 95% 46.1-95.1%). Valor predictivo negativo 74.2% (lC 95% 62-84.3%). Razón de verosimilitud positiva 6.4 (lC 95% 1.92 -21.3). Razón de verosimilitud negativa 0.66 (IC 95% 0.49-0.89). Área bajo la curva (AUC) = 0.656 (lC 95% 0.54-0.76).

Background: The way to evaluate the results of rectocolonic surgery in emergency conditions is a controversial aspect at present. The majority of the groups use for this analysis the measurement of the indices of morbidity and postoperative mortality. Several systems of score of scores are used for such aim. The obtained results are different, insufficient and uncertain, thus no of has a unanimous consensus for its use. Objectives: Identify which are the risk factors that influence in mortality in patients underwent to emergency colorectal surgery. Evaluate the capacity to predict mortality of those significative statistics factor. Place: High complexity private institution. Design: Consecutive, observational and retrospective. Patients: Patients underwent to emergency dry out colorectal surgery. Method: Analysis uni and multivariable of thirteen variables, preparation of a formula to predict death and its validation. Results: Ischemic disease, ASA score = or > IV and plasmatic urea = or > 80 mg% are predictors factor of death in patients undergo to emergency colorectal surgery. A prediction of death formula was done using the information of final predict model: (1/1 + exp - (-2.2+2.9 X 1+ 1.8 X2+1.7 X3)). The results of this formula were: Sensibility: 37% (lC 95% 19.3-57.7%). Specificity: 94.2% (lC 95% 84-98.8%). Positive Predictive Value: 76.9% (IC 95% 46.1-95.1%). Negative Predictive Value: 74.2% (lC 95% 62-84.3%). Positive Probability Reason: 6.4 (lC 95% 1.92 -21.3). Negative Probability Reason: 0.66 (IC 95% 0.49-0.89). Area under a Curve (AUC) = 0.656 (lC 95% 0.54-0.76).

A six-year-old female victim of sexual assault, with grade IV perineal injury with massive intestinal prolapse out of the perineum, is reported to highlight the severity of injury during sexual assaults.

Duplicación intestinal: diagnóstico y tratamiento de una condición inusual / Intestinal duplieation: diagnosis and treatment of an unusual condition

We report a 2.5 years old male presenting with abdominal pain, nausea and vomiting lasting 30 days. A CAT scan showed an intestinal duplication cyst. The patient was operated and a cystic lesion of 6 cm diameter was fond and excised along with five cm of terminal ileum. Intestinal transit was reconstituted with a terminal anastomosis between ileum and colon.

Reportamos el caso clínico de un paciente de 2 años y 6 meses de edad que fue intervenido quirúrgicamente por una duplicación intestinal del ileon terminal. Discutimos la presentación clínica, estudio radiológico, procedimiento quirúrgico y resultados del tratamiento. Revisamos la literatura actual pertinente haciendo énfasis en el diagnóstico y tratamiento de estas malformaciones por el potencial de malignidad que presentan en la vida adulta.
