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.

Falla intestinal. Artículo de revisión / Intestinal failure Review article

La falla intestinal (FI) se define como la disminución de la función del intestino por debajo de lo mínimo necesario para la absorción de los macronutrientes y / o agua y electrolitos, de tal manera que se requiere de la suplementación intravenosa (SIV) para mantener la salud y el crecimiento. Desde el punto de vista funcional se clasifica en tres tipos. FI tipo I: condición aguda, de corto duración y generalmente auto limitada, FI tipo II: estado agudo prolongado, a menudo en pacientes metabólicamente inestables, que requieren cuidado multidisciplinario y SIV durante períodos de una semana o meses, acompañada de complicaciones sépticas, metabólicas y nutricionales y FI tipo III: condición crónica, en pacientes metabólicamente estables, que requieren SIV durante meses o años. Su manejo requiere de terapia nutricional y en casos seleccionados cirugía autóloga de reconstrucción(AU)

Intestinal failure (FI) is defined as the decrease in intestinal function below the minimum necessary for the absorption of macronutrients and / or water and electrolytes, in such a way that intravenous supplementation (IVS) is required to maintain health and growth. From a functional point of view, it is classified into three types. FI type I: acute condition, of short duration and generally self-limited, FI type II: prolonged acute state, often in metabolically unstable patients, requiring multidisciplinary care and SIV for periods of a week or months, accompanied by septic, metabolic and nutrition and FI type III: chronic condition, in metabolically stable patients, who require SIV for months or years. Its management requires nutritional therapy and in selected cases autologous reconstruction surgery(AU)

Síndrome de Ehlers-Danlos hipermóvel: um relato de caso / Hypermobile Ehlers-Danlos syndrome: a case report

A síndrome de Ehlers-Danlos é estabelecida por distúrbios hereditários do tecido conjuntivo que tem como manifestações principais a hipermobilidade articular, a hiperextensibilidade da pele e a fragilidade de tecidos, como articulações, ligamentos, pele, vasos sanguíneos e órgãos internos. São reconhecidos 13 subtipos, de acordo com Classificação Internacional de 2017. Dentre estes, abordamos o hipermóvel, cujo diagnóstico é eminentemente clínico, com manifestações sistêmicas distintas. Esse artigo refere-se ao caso de uma paciente diagnosticada com síndrome de Ehlers-Danlos hipermóvel, tendo como intuito a atualização acerca dos novos critérios diagnósticos, assim como o diagnóstico precoce de tal raropatia.

Ehlers-Danlos syndrome is established through hereditary disorders of connective tissue, and has as its manifestations: joint hypermobility, skin hyperextensibility, and fragility of tissues such as joints, ligaments, skin, blood vessels, and internal organs. Thirteen subtypes have been recognized according to the 2017 International Classification. Among these, the hypermobile type, the diagnosis of which is eminently clinical, with distinct systemic manifestations, will be addressed. This article refers to the case of a patient diagnosed with hypermobile Ehlers-Danlos syndrome, with the objective of updating the new diagnostic criteria, as well as the early diagnosis of such a rare disease.

Intestinal perforation due to deep infiltrating endometriosis during pregnancy: case report / Rotura intestinal durante a gravidez devido a endometriose profunda infiltrativa: relato de caso

Abstract We report the case of a 33 year-old woman who complained of severe dysmenorrhea since menarche. From 2003 to 2009, she underwent 4 laparoscopies for the treatment of pain associated with endometriosis. After all four interventions, the pain recurred despite the use of gonadotropin-releasing hormone (GnRH) analogues and the insertion of a levonorgestrel intrauterine system (LNG-IUS). Finally, a colonoscopy performed in 2010 revealed rectosigmoid stenosis probably due to extrinsic compression. The patient was advised to get pregnant before treating the intestinal lesion. Spontaneous pregnancy occurred soon after LNG-IUS removal in 2011. In the 33rd week of pregnancy, the patient started to feel severe abdominal pain. No fever or sings of pelviperitonitis were present, but as the pain worsened, a cesarean section was performed, with the delivery of a premature healthy male, and an intestinal rupturewas identified. Severe peritoneal infection and sepsis ensued. A colostomy was performed, and the patient recovered after eight days in intensive care. Three months later, the colostomy was closed, and a new LNG-IUS was inserted. The patient then came to be treated by our multidisciplinary endometriosis team. The diagnostic evaluation revealed the presence of intestinal lesions with extrinsic compression of the rectum. She then underwent a laparoscopic excision of the endometriotic lesions, including an ovarian endometrioma, adhesiolysis and segmental colectomy in 2014. She is now fully recovered and planning a new pregnancy. A transvaginal ultrasound (TVUS) performed six months after surgery showed signs of pelvic adhesions, but no endometriotic lesions.

Resumo Relatamos o caso de uma mulher de 33 anos que apresentava de dismenorreia grave desde a menarca. Entre 2003 e 2009, a paciente foi submetida a quatro laparoscopias para o tratamento de dor associada à endometriose. A dor persistiu apos as 4 cirurgias apesar do uso de análogos do hormônio de liberação de gonadotropina (GnRH) e da inserção de um sistema intrauterino de levonorgestrel (SIU-LNG). Finalmente, uma colonoscopia realizada em 2010 revelou estenose rectosigmoide, provavelmente devido à compressão extrínseca. A paciente foi aconselhada a engravidar antes de tratar a lesão intestinal. A gravidez espontânea ocorreu logo após a remoção de LNGIUS em 2011. Na 33ª semana de gestação, a paciente começou a sentir dor abdominal intensa, sem febre ou sinais de peritonite. Como a dor piorou consideravelmente, a paciente foi submetida à cesariana com nascimento prematuro de um menino saudável. Durante a cesárea foi identificado rotura intestinal com peritonite grave e sepse. Uma colostomia foi realizada, e a paciente admitida no centro de terapia intensiva por 8 dais. A colostomia foi fechada e um novo SIU-LNG inserido. A paciente passou a ser tratada pela nossa equipe multidisciplinar de endometriose. A avaliação diagnóstica revelou a presença de lesões intestinais com compressão extrínseca do reto. Foi então submetida a uma excisão laparoscópica das lesões endometrióticas, incluindo umendometrioma ovariano, adesiólise e colectomia segmentar em 2014. Ela está agora totalmente recuperada e planeja nova gravidez. Uma ultrassonografia transvaginal (TVUS) realizada seis meses após a cirurgia revelou sinais de aderências pélvicas sem lesões de endometriose.

Evisceración vaginal tras tratamiento con radioterapia e histerectomía abdominal / Vaginal evisceration after treatment with radiotherapy and abdominal hysterectomy

La evisceración vaginal es una complicación muy rara. Es más frecuente en mujeres posmenopáusicas y con antecedente de cirugía vaginal, fundamentalmente histerectomía. También puede darse en mujeres premenopáusicas, vinculándose en estos casos a traumatismos, iatrogenia o introducción de cuerpos extraños. El íleon distal es el órgano más frecuentemente eviscerado, aunque el prolapso de epiplón, trompas de Falopio y apéndice también se han descrito. Presentamos el caso de una mujer de 43 años con evisceración transvaginal de epiplón a los seis meses de realizarse una histerectomía abdominal por recidiva de un cáncer escamoso de cérvix.

Vaginal evisceration is a very rare complication. It is more often in postmenopausal women with a history of vaginal surgery, mainly hysterectomy. It can also occur in premenopausal women, linking these cases to trauma, iatrogenic or foreign bodies. The distal ileum is most often gutted organ prolapse, although omentum, fallopian tubes and appendix are also described. We report a 43-year old transvaginal omental evisceration after six months of an abdominal hysterectomy for recurrent squamous cervical cancer.

Hernia del espacio de Petersen: complicación tardía del bypass gástrico laparoscópico / Petersen’s space hernia: late complication of laparoscopic gastric bypass

Introduction: Petersen's Space Hernia is a protrusion of intestinal loops through a defect between the alimentary loop and the transverse mesocolon that occur as a late complication of Gastric Bypass. Objective: To present our experience in the management of this entity, making emphasis on the difficulty of clinical diagnosis, the typical CT Scan findings and to suggest prevention and management strategies. Method: Case series study of patients with Petersen's Space Hernia after Laparoscopic Gastric Bypass. Clinical presentation, CT Scan findings and surgical results were analyzed. Results: 8 patients. Mean age 43 years. All presented al least 12 months after primary surgery, with unspecific abdominal pain. CT Scan most frequent findings were: Swirled mesentery, engorgement of mesentery vessels and the mushroom sign. Surgery was performed laparoscopically in the 8 patients. No bowel ischemia was found. In all cases, once reduced the protruded loops, complete closure of the defect with a running non absorbable suture was done. Conclusion: In patients with Gastric Bypass, presenting with abdominal pain, a high degree of suspicion must be kept about this entity. Clinical findings are unspecific and radiological study is crucial. When diagnosed on time bowel necrosis is avoided and the main surgical goal is to achieve a complete closure of the defect with non absorbable suture.

Introducción: La Hernia del Espacio de Petersen es una complicación tardía del bypass gástrico, que ocurre por la protrusión de asas intestinales a través del defecto que se genera entre el asa alimentaria y el mesocolon transverso. Objetivo: Presentar nuestra experiencia en el manejo de esta patología, haciendo énfasis en la dificultad del diagnóstico clínico, los hallazgos más típicos de la Tomografía Computada (TC) y sugerir estrategias de prevención y manejo. Método: Estudio de una serie de casos con diagnóstico de Hernia del Espacio de Petersen posterior a bypass gástrico. Se analizó la presentación clínica, los hallazgos imagenológicos e intraoperatorios y los resultados del tratamiento quirúrgico. Resultados: 8 pacientes. Todos se presentaron luego de 12 meses de la cirugía primaria y la manifestación fue dolor abdominal de carácter inespecífico. Los hallazgos más frecuentes de la TC fueron el "arremolinamiento" mesentérico, ingurgitación de los vasos mesentéricos y el "signo del hongo". La cirugía se realizó por vía laparoscópica en los 8 pacientes. No se evidenció isquemia intestinal. En todos los casos, una vez reducido el contenido herniado, se cerró el espacio con sutura continua de material no reabsorbible. No hubo complicaciones ni mortalidad. Conclusión: En los pacientes sometidos a bypass gástrico hay que mantener un alto grado de sospecha acerca de esta entidad. La clínica es inespecífica y el estudio imagenológico es fundamental. Pesquisado a tiempo se puede evitar la necrosis intestinal y el pilar fundamental del tratamiento es lograr un adecuado cierre del defecto con material no reabsorbible.

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.

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.

Tuberculosis intestinal secundaria: hallazgos morfológicos en un caso con desenlace fatal / Secondary intestinal tuberculosis: morphological findings in a fatal case

La tuberculosis gastrointestinal (TB GI) representa el 3-5 por ciento de todos los casos de TB extrapulmonar, reportándose que hasta el 20 por ciento de los sujetos con TB pulmonar presentan manifestaciones extra-pulmonares que incluyen enfermedades intra-abdominales, sin embargo, se desconoce la real incidencia del compromiso intestinal. La región ileocecal representa el sitio anatómico más frecuentemente afectado (85-90 por ciento), siendo actualmente la colonoscopía la herramienta diagnóstica de mayor utilidad. Se presentan los hallazgos morfológicos del examen post-mortem de una paciente en estudio por baja de peso y masa en región cecal. La necropsia realizada en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez Aravena de Temuco concluyó una TB pulmonar bilateral con compromiso secundario intestinal y linfonodal.

Gastrointestinal tuberculosis (TB GI) represents 3-5 percent of all cases of extrapulmonary TB, studies report that up to 20 percent of patients with pulmonary TB have extra-pulmonary manifestations. However, the real incidence of intestinal involvement is unknown. The ileocecal region is the anatomical site most frequently affected (85-90 percent), and colonoscopy is currently the most useful diagnostic tool. Post-mortem morphological elements of the examination of a patient with weight loss and cecal mass are presented. The necropsy performed at the Department of Pathology of the Hospital Hernán Henríquez of Temuco concluded a bilateral pulmonary TB with intestinal and lymph node involvement.

Correlation of DEFA1 Gene Copy Number Variation with Intestinal Involvement in Behcet's Disease

Copy number variation has been associated with various autoimmune diseases. We investigated the copy number (CN) of the DEFA1 gene encoding alpha-defensin-1 in samples from Korean individuals with Behcet's disease (BD) compared to healthy controls (HC). We recruited 55 BD patients and 35 HC. A duplex Taqman(R) real-time PCR assay was used to assess CN. Most samples (31.1%) had a CN of 5 with a mean CN of 5.4 +/- 0.2. There was no significant difference in the CN of the DEFA1 gene between BD patients and HC. A high DEFA1 gene CN was significantly associated with intestinal involvement in BD patients. Variable DEFA1 gene CNs were observed in both BD patients and HC and a high DEFA1 gene CN may be associated with susceptibility to intestinal involvement in BD.

Transanal small bowel evisceration following digital reduction of a chronically prolapsing rectum

Evisceration of the small bowel through a rectal perforation is rare. This is the case of a 66 year-old female presenting to the Accident and Emergency Department with transanal evisceration of her small bowel resulting from attempted digital reduction and subsequent tear of her chronically prolapsing rectum. Reduction of the prolapsed small bowel and primary repair of the rectal tear were carried out at laparotomy. The management of this case is discussed

First report of intestinal myiasis due to eristalis tenax in Iran

Eristalis tenax, belonging to order Diptera, family Syrphidae seldomly causes intestinal myiasis. Intestinal myiasis caused by E. tenax larvae is a rare manifestation found in both humans and other vertebrate animals. We report a 22-year-old woman presented with this myiasis. The larva in her stool sample was identified as E. tenax related to its typical morphology and authentic clues. Lack of specific control measures in the domestic water supply system was the most probable cause of this infestation

Curso de Reumatologia: aula 5: anti-inflamatórios não hormonais e alterações intestinais / Course of Rheumatology: class 5: nonsteroidal anti-inflammatory drugs and intestinal alterations

A enteropatia relacionada aos anti-inflamatórios não hormonais (ou não esteroides) é um processo gradual que envolve efeito tóxico direto à mucosa, lesão mitocondrial, quebra da integridade intercelular, recirculação êntero-hepática do anti-inflamatório e ativação neutrofílica pelo conteúdo intraluminal, inclusive por bactérias. A mediação pela cicloxigenase provavelmente é menos importante do que no trato gastrointestinal superior. Estudos com a nova modalidade endoscópica, como a que se utiliza de cápsula endoscópica, demonstram anormalidades relacionadas aos anti-inflamatórios não esteroides (AINEs), que incluem inflamação, erosões, fibrose, estenoses, lesões enantemáticas, erosões patequiais, perfurações e formação de membranas diafragmáticas no jejuno, íleo e colon.

Nonsteroidal anti-inflammatory drug enteropathy is a stepwise process involving direct mucosal toxity, mitochondrial damage, breakdown of intercellular integrity enterohepatic recirculation and neutrophil activation by liminal contents including bacteria. Unlike upper gastrointestinal toxity, cyclooxygenase-mediated mechanisms are probably less important. Newer imaging modalities such as capsule endoscopy studies demonstrate nonsteroidal anti-inflammatory drug-induced abonormalities that include inflammation, erosion, fibrosis, stricture, red spots, petechiae erosions, perforation, and formation of mucosal diaphragms in the jejunum, ileum and colon.

Gut prolapse into the perineum in a case of sexual assault.

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.

Comparison of the effects of lactated Ringer solution with and without hydroxyethyl starch fluid resuscitation on gut edema during severe splanchnic ischemia

The type of fluid used during resuscitation may have an important impact on tissue edema. We evaluated the impact of two different regimens of fluid resuscitation on hemodynamics and on lung and intestinal edema during splanchnic hypoperfusion in rabbits. The study included 16 female New Zealand rabbits (2.9 to 3.3 kg body weight, aged 8 to 12 months) with splanchnic ischemia induced by ligation of the superior mesenteric artery. The animals were randomized into two experimental groups: group I (N = 9) received 12 mL·kg-1·h-1 lactated Ringer solution and 20 mL/kg 6 percent hydroxyethyl starch solution; group II (N = 7) received 36 mL·kg-1·h-1 lactated Ringer solution and 20 mL/kg 0.9 percent saline. A segment from the ileum was isolated to be perfused. A tonometric catheter was placed in a second gut segment. Superior mesenteric artery (Q SMA) and aortic (Qaorta) flows were measured using ultrasonic flow probes. After 4 h of fluid resuscitation, tissue specimens were immediately removed for estimations of gut and lung edema. There were no differences in global and regional perfusion variables, lung wet-to-dry weight ratios and oxygenation indices between groups. Gut wet-to-dry weight ratio was significantly lower in the crystalloid/colloid-treated group (4.9 ± 1.5) than in the crystalloid-treated group (7.3 ± 2.4) (P < 0.05). In this model of intestinal ischemia, fluid resuscitation with crystalloids caused more gut edema than a combination of crystalloids and colloids.

Endometriosis profunda del tabique rectovaginal con compromiso intestinal: manejo quirúrgico con resección segmentaria de rectosigmoides / Deep infiltrating endometriosis of the rectovaginal space with intestinal commitment: surgical treatment

Presentamos 3 casos de endometriosis profunda del tabique rectovaginal con compromiso intestinal, en los cuales se realizó resección segmentaria del rectosigmoides para lograr la remoción completa de la enfermedad. Se analiza el cuadro clínico, manejo quirúrgico, complicaciones y seguimiento posterior. Revisamos la literatura a fin de establecer algunas pautas de manejo de esta entidad.

We reported 3 cases of deep endometriosis affecting the rectovaginal space with intestinal disease in which a rectosigmoides resection was required to achieve a complete surgical removal of disease. The clinical course, surgical management, complications and follow-up are analyzed. We review the literature to define some guidelines in the management of this entity.
