Colgajo de Martius como tratamiento de una fístula rectovaginal recidivada: revisión de la técnica quirúrgica a propósito de un caso clínico / Martius Flap for recurrent Rectovaginal Fístula: clinical Case and surgical approach

Resumen Introducción: La fístula rectovaginal es una patología quirúrgica compleja de tratar. El trauma perineal obstétrico y las enfermedades inflamatorias intestinales, especialmente la Enfermedad de Crohn son las causas más frecuentes. La reparación quirúrgica con un Colgajo de Martius en manos experimentadas ha mostrado buenos resultados con mínima morbilidad en pacientes seleccionados. Material y Método: Presentamos un caso clínico de una paciente que cursó con una fístula rectovaginal posparto tardía, la cual tuvo una recurrencia precoz, luego de intentar tratamiento quirúrgico consistente en un colgajo de avance, siendo necesaria la desfuncionalización del tránsito con una colostomía en asa. Posteriormente se realizó un Colgajo de Martius con resultado exitoso. Resultados: Evolución satisfactoria. Cursó con dehiscencia de la herida perineal la cual requirió solo curaciones ambulatorias. Luego de 8 meses posterior a la confección del Colgajo de Martius, se realizó el cierre de colostomía. A los 30 meses poscolgajo, la paciente se encuentra en buenas condiciones, sin evidencia de recidiva y tránsito intestinal normal. Conclusión: En este caso clínico, el colgajo de Martius fue una alternativa segura y efectiva en el tratamiento de una fístula rectovaginal recidivada.

Introduction: The rectovaginal fistula is a complex surgical pathology to treat. Obstetric perineal trauma and inflammatory bowel diseases, especially Crohn's disease, are the most frequent causes. Surgical repair with a Martius flap in experienced hands has shown good results with minimal morbidity in selected patients. Material and Methods: We present a clinical case of a patient who had a late postpartum rectovaginal fistula, which recurred early after attempting surgical treatment consisting of an advancement flap, requiring defunctionalization of the transit with a loop colostomy. Subsequently, a Martius flap was performed with a successful result. Results: Satisfactory evolution. The patient presented a dehiscence of the perineal wound which required only ambulatory dressings. At 8 months from the Martius flap was made, the colostomy was closed. At 30 months post-flap, the patient is in good condition, with no evidence of recurrence and normal intestinal transit. Conclusión: In this clinical case, the Martius flap was a safe and effective alternative in the treatment of a recurrent rectovaginal fistula.

Chinese experts consensus on diagnosis and treatment of rectovaginal fistula (2022 edition) / 中华胃肠外科杂志

Rectovaginal fistula (RVF) is an abnormal connection between the rectum and the vagina. At present, the principle method for RVF is surgery. With a variety of surgical methods, clinicians still lack a generally recognized consensus on RVF. Therefore, based on latest evidence from literature and expert experience, the Clinical Guidelines Committee of Chinese Medical Doctor Association Anorectal Branch organized domestic experts in anorectal surgery and gynecology to discuss the etiology, classification, diagnosis, treatment and special types of rectovaginal fistula of RVF, through questionnaires and expert seminars. "Chinese experts consensus on the diagnosis and treatment of rectovaginal fistula (2022 edition)" was produced in order to deepen the understanding of RVF, and to provide a standardized treatment for RVF in order to reduce the failure rate of surgery.

Rectovaginal fistula: An early complication of radiotherapy in a sexagenarian with cervical cancer

A 62-year-old Nigerian woman was admitted on account of cervical carcinoma Stage IV and was requested to undergo radiotherapy and chemotherapy. Six weeks after commencing this treatment she starting passing feces involuntarily through the vagina. Imaging studies revealed a high sited, medium sized, and rectovaginal fistula (RVF). RVFs have been documented as a late complication of radiotherapy for any gynecological malignancy but it occurred earlier in this patient. A preliminary surgical procedure, a sigmoid-ostomy, was performed successfully and a definitive surgery, a sigmoido-rectal anastomosis, was planned to be done in 18 months after the diagnosis of the RVF but the patient died shortly after the first procedure. The present case indicates that a RVF can occur as an early complication of radiotherapy even when it presents with mild symptoms.

Síndrome de Mayer-Rokitansky- Küster-Hauser asociado con malformación anorectal / Mayer-Rokitansky-Küster-Hauser syndrome associated with anorectal malformation

La agenesia vaginal es una entidad poco frecuente que puede presentarse en forma aislada o acompañada de otras anomalías congénitas. El desconocimiento de esta asociación puede retardar su diagnóstico, causar complicaciones indeseadas y comprometer el resultado del tratamiento. Se describen tres casos clínicos con agenesia vaginal y malformación anorrectal, cuyos diagnósticos no fueron realizados en el momento del nacimiento. Aunque la coexistencia de anomalías vaginales y anorectales sean poco frecuentes, los médicos responsables de su tratamiento deben ser conscientes de su existencia y practicar examen perineal cuidadoso.

Vaginal agenesis is a rare condition. It may exist in isolation or be associated with other congenital anomalies. A lack of awareness on this association may delay diagnosis, cause undesirable complications and compromise treatment outcomes. We describe three cases of vaginal agenesis associated with anorectal malformation which were not diagnosed at birth. Although the coexistence of vaginal and anorectal anomalies is uncommon, treating physicians should be aware of them and perform a detailed perineal examination.

Gracilis pull-through flap for the repair of a recalcitrant recto-vaginal fistula

Recto-vaginal fistulas are difficult to treat due to their high recurrence rate. Currently, no single surgical intervention is universally regarded as the best treatment option for rectovaginal fistulas. We present a case of recurrent recto-vaginal fistula surgically treated with a gracilis pull-through flap. The surgical goals in this patient were complete excision of the recto-vaginal fistula and introduction of fresh, vascularized muscle to seal the fistula. A defunctioning colostomy was performed 1 month prior to the present procedure. The gracilis muscle and tendon were mobilized, pulled through the freshened recto-vaginal fistula, passed through the anus, and anchored externally. Excess muscle and tendon were trimmed 1 week after the procedure. Follow-up at 4 weeks demonstrated complete mucosal coverage over an intact gracilis muscle, and no leakage. At 8 weeks post-procedure, the patient resumed sexual intercourse with no dyspareunia. At 6 months post-procedure, her stoma was closed. The patient reported transient fecal staining of her vagina after stoma reversal, which resolved with conservative treatment. The fistula had not recurred at 20 months post-procedure. The gracilis pull-through flap is a reliable technique for a scarred vagina with an attenuated rectovaginal septum. It can function as a well-vascularized tissue plug to promote healing.

Optimal strategies of rectovaginal fistula after rectal cancer surgery

PURPOSE: Rectovaginal fistula (RVF) after low anterior resection for rectal cancer is a type of anastomotic leakage. The aim of this study was to find out the difference of leakage, according to RVF presence or absence and to identify the optimal strategy for RVF. METHODS: All female patients who underwent low anterior resection with colorectal anastomosis or coloanal anastomosis (n = 950) were retrospectively analyzed. Patients' demographics and perioperative outcomes were analyzed between the RVF group and leakage without the RVF (nRVF) group. We performed 4 types of procedures—primary repair, diverting stoma, redo coloanal anastomosis (RCA), and conservative procedure—to treat RVF, and calculated the success rates of each type of procedure. RESULTS: The leakage occurred in 47 patients (4.9%). Among them, 18 patients (1.9%) underwent an RVF and 29 (3.0%) underwent nRVF. The RVF group received more perioperative radiotherapy (27.8% vs. 3.4%, P < 0.015) and occurred late onset after surgery (181.3 ± 176.4 days vs. 23.2 ± 53.6 days, P < 0.001) more than did the nRVF group. In multivariate analysis for the risk factor of the RVF group, the RVF group was statistically associated with less than 5 cm of anastomosis more than was the no-leakage group. A total of 35 procedures were performed in 18 patients with RVF for treatment. RCA showed satisfactory success rates (85.7%, n = 6) and, primary repair (transanal or transvaginal) showed acceptable success rate (33.3%, n = 8). CONCLUSION: After low anterior resection for rectal cancer, RVF was strongly correlated with a lower level of primary tumor location. Among the patients who underwent leakages, receipt of perioperative radiotherapy was significantly high in the RVF group than that of the nRVF group. Additionally, this study suggests that RCA might be considered another successful treatment strategy for RVF.

Outcomes of surgical treatments for rectovaginal fistula and prognostic factors for successful closure: a single-center tertiary hospital experiences

PURPOSE: Rectovaginal fistula can result from various causes and diverse surgical procedures have developed as a result. We investigated the outcomes of surgical treatments for rectovaginal fistula according to causes and procedures. METHODS: Between 1998 and 2016, 92 patients underwent 128 operations for rectovaginal fistula. Prospectively collected data were recorded, and a retrospective review was conducted. RESULTS: The median age was 49 years, and low fistula occurred in 58 patients (63.0%). The most common cause was radiation therapy, followed by pelvic operation, birth injury, perineal operation, cancer invasion, and trauma. The most common procedure during the first operation was diverting ostomy alone, followed by transanal rectal advancement flap, sphincteroplasty with perineoplasty, bowel resection, fistulectomy with seton placement, and Martius flap. Thirty-one patients (33.7%) experienced successful closure after the first operation. Repeated operations were performed in 16 patients (17.4%), including gracilis muscle transpositions, stem cell injections, and Martius flaps. The overall success rate was 42.4% (n = 39). Radiation therapy and pelvic operation as cause of fistula were significantly poor prognostic factors (P = 0.010, P = 0.045) and Crohn disease had a tendency for poor prognostic factors (P = 0.058). CONCLUSION: Radiation therapy and pelvic operation for cancer were more common causes than birth injury, and these causes of rectovaginal fistula were the most important prognostic factors. An individualized approach and repeated surgeries with complex or newly developed procedures, even among high-risk causes of fistula, may be necessary to achieve successful closure.

Currarino syndrome in an adult woman

Currarino syndrome is a hereditary disease characterized by the triad of sacral agenesis, anorectal malformation, and presacral mass. Most patients are diagnosed in childhood, and this condition rarely manifests in adulthood. In women, gynecological malformations associated with Currarino syndrome have been reported, such as bicornuate uterus, rectovaginal fistula, and septate uterus. We present a rare case of a 29-year-old woman with a suspected pelvic mass who was diagnosed with Currarino syndrome.

Manejo de la fístula ano-recto-vaginal compleja mediante el procedimiento de Martius: reporte de cinco casos / Martius procedure in complex anorectal-vaginal fistula management: five-case report

La reparación de fístulas ano-recto-vaginales complejas representa un reto anatomoquirúrgico para el cirujano, debiendo seleccionarse el procedimiento quirúrgico adecuado para cada caso. El procedimiento de Martius consiste en la trasposición del músculo bulbocavernoso para reparar la fístula recto-vaginal. Se presentan cinco casos de fístulas ano-recto-vaginales reparadas por este procedimiento desde el 2010 hasta el 2014. La edad promedio fue de 38,2 años, tres fístulas (60%) fueron de etiología obstétrica, una inducida por radiación y otra de etiología desconocida. El seguimiento promedio fue de 25 meses, con una tasa de éxito de 100%. El procedimiento de Martius es una buena alternativa para la reparación quirúrgica de fístulas ano-recto-vaginales complejas.

The repair of complex anorectal-vaginal fistulas represents an anatomic-surgical challenge for the surgeon, and the appropriate surgical procedure must be selected for each case. The procedure of Martius is described as the transposition of the bulbocavernosus muscle to repair the recto-vaginal fistula. Five cases of anorectal-vaginal fistulae were repaired by this procedure from 2010 to 2014. The mean age was 38.2 years; three fistulas (60%) were of obstetric etiology, one induced by radiation and one of unknown etiology. The mean follow-up was 25 months, with a 100% success rate. The Martius procedure is a good alternative for the surgical repair of complex anorectal-vaginal fistulas.

Atresia anal com fístula retovaginal em ovino: relato de caso / Anal Atresia with rectovaginal fistula in sheep: case report

A atresia anal com fístula retovaginal, é considerada uma afecção congênita rara nos ovinos. Em virtude disso, buscou-se descrever o reparo cirúrgico e cuidados pós-operatórios em uma borrega que apresentava essa afecção. Nesse sentido, uma borrega, sem raça definida, de 25 dias de idade e pesando 7,2kg, apresentou sinais de distensão abdominal e defecação pela vulva. A afecção foi diagnosticada por meio do exame clínico e confirmada radiograficamente, constatando-se atresia anal do tipo III em associação com a fístula.(AU)

Atresia ani associated with rectovaginal fistula is considered a rare congenital anomaly in sheep. Therefore, the surgical correction and post-operative care of a lamb presenting atresia ani with rectovaginal fistula has been detailed in this case report. A 25-days old, mixed breed lamb, weighing 7.2 kg, showing signs of abdominal bloating, and stool passage through the vulva was admitted at our hospital. An atresia ani type III condition associated with rectovaginal fistula was diagnosed by clinical examination and confirmed by radiographic examination.(AU)

Alternativas quirúrgicas en el manejo de la fístula rectovaginal: experiencia de 25 años / Surgical procedures for rectovaginal fistula: 25-years experience

Antecedentes: La fístula rectovaginal (FRV) es una patología de origen muy variado y el tratamiento representa un verdadero desafío terapéutico. No existen estudios prospectivos que orienten sobre el manejo de estas lesiones. Objetivo: Evaluar los resultados del tratamiento quirúrgico de las pacientes con una FRV. Material y método: Estudio descriptivo retrospectivo en el cual se incluyen todas las pacientes intervenidas en un periodo de 25 años. Resultados: Se trata de 63 pacientes con una FRV, la mitad secundaria a una neoplasia y un 27% secundaria al tratamiento radiante de tumores pélvicos. El trauma local y las FRV postoperatorias representan el 28% de los casos. El abordaje de la FRV fue abdominal en 26 pacientes (41%), resecando la FRV neoplásica en 11 y efectuando una cirugía reconstructiva en 15 actínicas. En 17 pacientes con una FRV por persistencia tumoral solo se efectuó una desfuncionalización proximal. De las 5 pacientes con una FRV iatrogénica, en 4 se logró el cierre espontáneo mediante una ostomía transitoria y los 7 casos de FRV posparto fueron reparadas con un abordaje local con resultados satisfactorios en 6. Conclusiones: En este estudio el abordaje local de la FRV se utilizó en 12 casos; el 33% (21/63) de los casos necesitó una ostomía definitiva y en el 40% de las fístulas complejas se logró el cierre de la fístula con conservación esfinteriana. Las series de FRV publicadas son muy heterogéneas, probablemente debido a patrones de referencia muy variables, lo que hace muy difícil realizar un análisis comparativo.

Background: Rectovaginal fistula (RVF) is a distressing condition with no generally accepted standard surgical management. Aim: To assess results of surgery for RVF. Material and method: This is a descriptive retrospective analysis of 63 patients operated on consecutively for RVF in a period of 25 years. Results: Halve of the cases were secondary to a pelvic malignancy and 27% due to radiotherapy of pelvic tumors. RVFs were associated with local (obstetrical) trauma and postsurgical complications in 28% of the cases. High RVFs were approached through abdominal procedures in 26 patients (41%), including radical resection of the primary tumor in 11 cases and coloanal sleeve anastomosis procedure in 15 patients with a RVF due to pelvic radiation. Seventeen patients with persistent pelvic tumors after radiotherapy and/or surgery were handled with a colostomy or ileostomy to improve quality of life. Four of five cases with postsurgical RVF closed spontaneously with a proximal colostomy and, in seven patients with obstetrical RVF, an advancement flaps were performed, with success in 6. Conclusions: In this study local repair of RVF was employed in 12 cases, one third of the cases needed a permanent ostomy, and 40% of the complex cases of RVF were successfully repaired with sphincter preservation. Comparisons with other studies are precluded because of heterogeneity of published RVF series, probably due to different patterns of reference.

Anterior Anorectocolonic Tubular Duplication Presenting as Rectovestibular Fistula in an Infant / 소아외과

Anorectal duplications account for only 5% of gastrointestinal duplications, and cases with involvement of the anal canal are much rarer. Nearly all anorectal duplications are posterior to the rectum; duplications located anterior to the normal rectum are highly unusual, and only a few cases have been reported. We report the case of an anterior anorectocolonic duplication presenting as a rectovaginal fistula in a 2-month-old infant. After diagnosis, the duplication was excised completely without further intestinal complications.

Early Experience With a Partial Stapled Hemorrhoidopexy for Treating Patients With Grades III–IV Prolapsing Hemorrhoids

PURPOSE: Circular stapled hemorrhoidopexy (CSH) is widely used to treat patients with grades III–IV hemorrhoids because of less pain and short hospital stay. However, this procedure is associated with some complications, such as urge to defecate, anal stenosis, staple line dehiscence, abscess and sepsis. To avoid these complications, surgeons perform a partial stapled hemorrhoidopexy (PSH). The aim of this study is to present our early experience with the PSH. METHODS: We retrospectively reviewed the medical records of 58 patients with hemorrhoids who were treated with a PSH at Busan Hang-Un Hospital from January 2016 to June 2016. A specially designed tri-window anoscope was used, and a purse string suture was made at the mucosae of the protruding hemorrhoids through the window of the anoscope. The hemorrhoidopexy was done by using a circular stapler. RESULTS: Of the 58 patients included in this study, 34 were male and 24 were female patients (mean age, 50.4 years). The mean operation time was 12.4 minutes, and the mean postoperative hospital stay was 3.8 days. Three patients experienced bleeding (5.1%) 5 urinary retention (8.6%) and 5 skin tags (8.6%). Urge to defecate, tenesmus, abscess, rectovaginal fistula, anal stricture, incontinence, and recurrence did not occur. CONCLUSION: PSH is a minimally invasive, feasible, and safe technique for treating patients with grades III–IV hemorrhoids. A PSH, instead of a CSH, can be used to treat certain patients with hemorrhoids.
