Multidisciplinary approach to evaluation of rectovaginal fistulas.

Thorough evaluation of a rectovaginal fistula is essential to optimize surgical repair. The underlying cause should be addressed and treated, which can affect the timing and the approach to repair. It is imperative to be well prepared because the highest chance of successful closure occurs during the initial repair attempt. Our objective was to demonstrate how multidisciplinary colorectal surgery and urogynecology teams use specific methods during the examination under anesthesia to evaluate a complex rectovaginal fistula and to optimize the surgical approach to repair. Anesthesia may be provided with monitored anesthesia care and a posterior perineal block. This pain control allows for a wide range of techniques to evaluate the fistula using anoscopy, fistula probe, hydrogen peroxide, and sigmoidoscopy. In addition, the teams show how curettage and subsequent seton placement can encourage closure by secondary intention and decrease the risk of abscess formation, respectively.

Rectovaginal Fistula: What Is the Role of Martius Flap and Gracilis Muscle Interposition in the Therapeutic Strategy?

BACKGROUND: Although numerous treatments exist for the management of rectovaginal fistula, none has demonstrated its superiority. The role of diverting stoma remains controversial. A few series include Martius flap in the armamentarium. OBJECTIVE: Determine the role of gracilis muscle interposition and Martius flap in the surgical management of rectovaginal fistula. DESIGN: Retrospective cohort study of a pooled prospectively maintained database from 3 centers. PATIENTS: All consecutive eligible patients with rectovaginal fistula undergoing Martius flap and gracilis muscle interposition were included from 2001 to 2022. MAIN OUTCOME MEASURES: Success was defined by the absence of stoma and rectovaginal fistula. RESULTS: Sixty-two patients were included with 55 Martius flap and 24 gracilis muscle interposition performed after failures of 164 initial procedures. Total length of stay was longer for gracilis muscle interposition by 2 days ( p = 0.01) without a significant difference in severe morbidity (20% vs 12%, p = 0.53). Twenty-seven percent of the Martius flap interpositions were performed without a stoma, which did not have an impact on overall morbidity ( p = 0.763). Per patient immediate success rates were not significantly different between groups (35% vs 31%, p > 0.99). The success of gracilis muscle interposition after the failure of the Martius flap was not significantly different from an initial gracilis muscle interposition ( p > 0.99). After simple perineal procedures, the immediate success rate rose to 49.4% (49% vs 50%, p > 0.99). After a median follow-up of 23 months, no significant difference was detected in success rate between the 2 procedures (69% vs 69%, p > 0.99). Smoking was the only negative predictive factor ( p = 0.02). LIMITATIONS: By its retrospective nature, this study is limited in its comparison. CONCLUSIONS: This novel comparison between Martius flap and gracilis muscle interposition suggests that Martius flap presents several advantages, including shorter length of stay, similar morbidity, and similar success rate. Proximal diversion via a stoma for Martius flap does not appear mandatory. Gracilis muscle interposition could be reserved as a salvage procedure after Martius flap failure. See Video Abstract . FSTULA RECTOVAGINAL CUL ES EL ROL DEL COLGAJO DE MARTIUS Y LA INTERPOSICIN DEL MSCULO GRACILIS EN LA ESTRATEGIA TERAPUTICA: ANTECEDENTES:Si bien existen numerosos tratamientos para el manejo de la fistula rectovaginal, ninguno ha demostrado su superioridad. El papel del estoma de derivación sigue siendo controvertido. Pocas series incluyen colgajo de Martius en el armamento.OBJETIVO:Determinar el rol de la interposición del músculo gracilis y del colgajo de Martius, en el manejo quirúrgico de la fístula rectovaginal.DISEÑO:Estudio de cohorte retrospectivo de una base de datos mantenida prospectivamente en 3 centros.AJUSTES/PACIENTES:Se incluyeron todos los pacientes elegibles consecutivos con fistula rectovaginal sometidos a colgajo de Martius y la interposición del músculo gracilis desde 2001 hasta 2022.RESULTADOS PRINCIPALES:El éxito se definió por la ausencia de estoma y fistula rectovaginal.RESULTADOS:Se incluyeron 62 pacientes con 55 colgajo de Martius y 24 con interposición del músculo gracilis realizados después de fracasos de 164 procedimientos iniciales. La duración total de la estancia hospitalaria fue dos días más larga para la interposición del músculo gracilis ( p = 0,01) sin una diferencia significativa en la morbilidad grave (20% frente a 12%, p = 0,53). El 27% de los colgajos de Martius se realizaron sin estoma, sin impacto en la morbilidad global ( p = 0,763). Las tasas de éxito inmediato por paciente no fueron significativamente diferentes entre los grupos (35% vs. 31%, p = 1,0). El éxito de la interposición del músculo gracilis después del fracaso del colgajo de Martius no fue significativamente diferente de una interposición del músculo gracilis inicial (p = 1,0). La tasa de éxito inmediato aumentó al 49,4% (49% frente a 50%, p = 1,0) después de procedimientos perineales simples. Después de una mediana de seguimiento de 23 meses, no se detectaron diferencias significativas en la tasa de éxito entre los dos procedimientos (69 % frente a 69 %, p = 1,0). El tabaquismo fue el único factor predictivo negativo ( p = 0,02).LIMITACIONES:Por su naturaleza retrospectiva, este estudio tiene limitaciones en su comparación.CONCLUSIÓN:Esta novedosa comparación entre colgajo de Martius y la interposición del músculo gracilis sugiere que el colgajo de Martius presenta varias ventajas, incluida una estancia prolongada más corta, una morbilidad similar y un éxito. La derivación proximal a través de un estoma para el colgajo de Martius no parece obligatoria. La interposición del músculo gracilis podría reservarse como procedimiento de rescate después de una falla de colgajo de Martius. (Traducción-Dr. Aurian Garcia Gonzalez ).

Treatment techniques for rectovaginal fistulas after low rectal resection for deep endometriosis.

Endometriosis is a benign gynecologic affection that may lead to major surgeries, such as colorectal resections. Rectovaginal fistulas (RVF) are among the possible complications. When they occur, it is necessary to adapt the repair surgery as best as possible to limit their functional consequences. This video shows three different techniques for correcting RVF after rectal resection for endometriosis, with a combination of perineal surgery and laparoscopy: a mucosal flap, a transanal transection and single stapled anastomosis (TTSS) and a pull through.

HIV-associated rectovaginal fistulae in children: a single-centre retrospective study in the antiretroviral era.

PURPOSE: Acquired rectovaginal fistulae (RVF) are a complication of paediatric HIV infection. We report our experience with the surgical management of this condition. METHODS: We retrospectively reviewed the records of paediatric patients with HIV-associated RVF managed at Chris Hani Baragwanath Academic Hospital (2011-2023). Information about HIV management, surgical history, and long-term outcomes was collected. RESULTS: Ten patients with HIV-associated RVF were identified. Median age of presentation was 2 years (IQR: 1-3 years). Nine patients (9/10) underwent diverting colostomy, while one demised before the stoma was fashioned. Fistula repair was performed a median of 17 months (IQR: 7.5-55 months) after colostomy. An ischiorectal fat pad was interposed in 5/9 patients. Four (4/9) patients had fistula recurrence, 2/9 patients developed anal stenosis, and 3/9 perineal sepsis. Stoma reversal was performed a median of 16 months (IQR: 3-25 months) after repair. Seven patients (7/9) have good outcomes without soiling, while 2/9 have long-term stomas. Failure to maintain viral suppression after repair was significantly associated with fistula recurrence and complications (φ = 0.8, p < 0.05). CONCLUSION: While HIV-associated RVFs remain a challenging condition, successful surgical treatment is possible. Viral suppression is a necessary condition for good outcomes.

Transanal fistula repair for the treatment of rectovestibular fistula with normal anus in female children: a 5-year single-center experience.

PURPOSE: The purpose of this study was to review a 5-year operative experience of transanal fistula repair for the treatment of rectovestibular fistula with a normal anus in female children. METHODS: In this study, we conducted a retrospective review of children diagnosed with rectovestibular fistula with normal anus who underwent transanal fistula repair in the department of General Surgery, Children's Hospital of Chongqing Medical University. Clinical data were retrospectively analyzed. RESULTS: A total of 56 female children were included in the study. The patients' ages ranged from 1 year 10 months to 15 years 11 months, with an average age of 5 years 1 month. These children had a clear history of gas or loose stool leakage through the vestibular area, with or without a history of vestibular infection. All patients had a normal anus and underwent transanal fistula repair. Follow-up was conducted through telephone or outpatient visits for a duration of 10 months to 5 years (average follow-up duration 19 months). Three patients experienced minimal secretion from the external orifice of the vestibular fistula within two weeks after the operation, but were successfully treated with sitting bath therapy without any relapse. Another three cases had a recurrence of the fistula, and two of them underwent transanal fistula repair at our center again, resulting in a successful cure after reoperation. The remaining case has not yet undergone reoperation. In the long-term follow-up, all the children had satisfactory anal appearance, with no fecal incontinence, anorectal stenosis, or fistula infection. CONCLUSION: Transanal fistula repair is a simple, safe, and effective surgical method to treat female children with rectovestibular fistula with a normal anus.

Extraperitoneal Cesarean Section after two Medial Laparotomies, Anus Prater, and Surgical Treatment of the Rectovaginal Fistula in a Patient with Crohn's Disease: A Case Report.

The aim of this case report is to show the advantages of the extraperitoneal cesarean section (ECS) approach in a pregnant patient with multiple previous abdominal transperitoneal colon surgeries and Crohn's disease. A pregnant nulliparous woman with Crohn's disease was admitted for delivery. After delivery, a large rupture and lesion of the rectum was observed. Suturing of the vagina, rectum and sphincter was performed by an abdominal surgeon. Because of a very large and irregularly shaped rectum rupture, the patient underwent infraumbilical medial laparotomy and sigmoidostomy. After 18 months, the patient started to experience vaginal discharge and Y-shaped rectovaginal fistula was confirmed. Surgical reconstruction was performed. The patient's second pregnancy began one year later. At 38 weeks of pregnancy, elective extraperitoneal cesarean section was performed. A healthy newborn was delivered. Follow-up showed full and fast recovery after the ECS. In cases of pregnant women who have had multiple colon surgeries, gynecology surgeons can choose to perform an ECS to avoid transperitoneal entrance into the abdomen. ECS avoids lysis of postoperative adhesions after repetitive gastrointestinal surgeries, the formation of new adhesions by lysis of the old adhesions, and most importantly, the possibility of colon or small intestine lesions during lysis of dense or firm adhesions.

Gracilis Muscle Interposition for the Treatment of Rectovaginal Fistula: A Systematic Review and Pooled Analysis.

BACKGROUND: A rectovaginal fistula is a debilitating condition that often severely impacts quality of life. Despite many treatment options available, the best surgical treatment is far from being established, and many patients will undergo several procedures before fistula closure is achieved. Gracilis muscle interposition, which is the transposition of the gracilis muscle into the rectovaginal septum, is an option for complex and persistent fistulas, but literature on the subject is scarce, mainly consisting of small case series. OBJECTIVE: This study aimed to assess the success rate of gracilis muscle interposition for the surgical treatment of rectovaginal fistula. DATA SOURCES: MEDLINE, Embase, Cochrane Library, and Web of Science. STUDY SELECTION: Studies comprising at least 5 patients who underwent gracilis muscle interposition for rectovaginal fistula were included. No date or language restrictions was applied. INTERVENTION: Gracilis muscle interposition. MAIN OUTCOME MEASURES: The primary outcome is the fistula closure rate (%). Other domains analyzed are stoma closure rate, postoperative complications, quality of life, fecal continence, and sexual function. RESULTS: Twenty studies were included for a total of 384 patients. The pooled fistula closure rate for gracilis muscle interposition was 64% (95% CI, 53%-74%; range, 33%-100%). Risk factors for failure were smoking, underlying Crohn's disease, and more than 2 previous repairs, whereas stoma formation was associated with improved outcomes. Postoperative complications ranged from 0% to 37%, mostly related to surgical site occurrences at the harvest site and perineal area. No deaths occurred. Gracilis muscle interposition improved quality of life and fecal continence, but impairment of sexual function was common. LIMITATIONS: Most of the included studies were small case series. CONCLUSIONS: Gracilis muscle interposition is a safe and moderately effective treatment that could be taken into consideration as second- or third-line therapy for recurrent rectovaginal fistula.

Turnbull-Cutait Pull-Through Procedure Is an Alternative to Permanent Ostomy in Patients With Complex Pelvic Fistulas.

BACKGROUND: A permanent stoma is frequently recommended in the setting of complex or recurrent rectovaginal fistulas because of the high failure rate of reconstructive procedures. The Turnbull-Cutait pull-through procedure is a salvage operation for motivated patients desiring to avoid permanent fecal diversion. OBJECTIVE: To analyze the cure rates of complex rectovaginal fistulas after the Turnbull-Cutait pull-through procedure based on cause. DESIGN: After the institutional review approval board, a retrospective review of women who underwent the procedure (1993-2018) for a rectovaginal fistula was conducted. Patients' demographics, cause, and postoperative outcomes were analyzed. SETTING: Colorectal surgery department at a tertiary center in the United States. PATIENTS: Adult women with a rectovaginal fistula who underwent a colonic pull-through procedure were included. MAIN OUTCOME MEASURES: Recurrence after the colonic pull-through procedure. RESULTS: There were 81 patients who underwent colonic pull-through; of those, 26 patients had a rectovaginal fistula, had a median age of 51 (43-57) years, and had a mean BMI of 28 ± 3.2 kg/m 2 . A total of 4 patients (15%) had a recurrence and 85% of the patients healed. Ninety-three percent of the patients healed after the prior anastomotic leak. Patients with a Crohn's disease-related fistula had a 75% cure rate. The Kaplan-Meier analysis showed a cumulative incidence of recurrence of 8% (95% CI, 0%-8%) within 6 months after surgery and 12% at 12 months. LIMITATIONS: Retrospective design. CONCLUSIONS: The Turnbull-Cutait pull-through procedure may be the last option to preserve intestinal continuity and successfully treat rectovaginal fistulas in 85% of cases.

Gracilis Flap Repair for Reoperative Rectovaginal Fistula.

BACKGROUND: Surgical treatment of recurrent rectovaginal fistulas is notoriously difficult. Placement of the gracilis muscle between the vagina and anus is an advanced technique used to close persistent fistulas. We have utilized this procedure for recalcitrant fistulas and hypothesized that a gracilis interposition would offer a good treatment option for patients with refractory rectovaginal fistulas, regardless of underlying etiology. OBJECTIVE: The purpose of this study was to investigate healing rates of gracilis interposition in patients with refractory rectovaginal fistulas. DESIGN: Following institutional review board approval, a retrospective review of all adult female patients with a diagnosis of rectovaginal fistula between January 2009 and August 2020 was performed; those who underwent gracilis interposition for definitive fistula closure were included for analysis. SETTINGS: The study was conducted at a colorectal surgery department at a tertiary center in the United States. PATIENTS: All patients were adult females with a diagnosis of a rectovaginal fistula who underwent gracilis interposition for definitive closure. MAIN OUTCOME MEASURES: Patient demographics, etiology of rectovaginal fistula, previous surgical intervention, presence of intestinal diversion, operative details, 30-day morbidity, recurrence of fistula, and time to recurrence. Fistula closure was defined as lack of clinical symptoms following stoma closure, negative fistula detection on gastrograffin enema' and absence of an internal opening at examination under anesthesia. RESULTS: Twenty-two patients were included who had a median age of 43 years (range, 19-64 years) and median body mass index of 31 kg/m 2 (range, 22-51). Median time between prior attempted surgical repair and gracilis surgery was 7 months (range, 3-17). The number of previously attempted repairs were 1-2 (n = 8), 3-4 (n = 9), and > 4 (n = 5). The most recent attempted surgical repair was rectal advancement flap (n = 7), transperineal +/- Martius flap (n = 4), episioproctotomy (n = 3), transvaginal repair (n = 2), and other (n = 6). All patients had fecal diversion at the time of gracilis surgery. Thirty-day postoperative surgical site infection at the graft/donor site was 32% (n = 7). At a median follow-up of 22 months (range 2-62), fistula closure was 59% (n = 13). Gracilis interposition was successful in all inflammatory bowel disease patients. LIMITATIONS: The study was limited by its retrospective nature. CONCLUSIONS: Gracilis interposition is an effective operative technique for reoperative rectovaginal fistula closure. Patients should be counseled regarding the possibility of graft/donor site infection. See Video Abstract at http://links.lww.com/DCR/B763 . REPARACIN CON COLGAJO DE GRACILIS PARA LA FSTULA RECTOVAGINAL REOPERATORIA: ANTECEDENTES:El tratamiento quirúrgico de las fístulas rectovaginales recurrentes es muy difícil. La colocación del músculo gracilis entre la vagina y el ano es una técnica avanzada que se utiliza para cerrar las fístulas persistentes.

El cierre de la fístula se definió como la ausencia de síntomas clínicos después del cierre del estoma, la detección negativa de la fístula en el enema de gastrograffin y la ausencia de una abertura interna en el examen bajo anestesia.RESULTADOS:Se incluyeron 22 pacientes que tenían una mediana de edad de 43 años (rango 19-64 años) y una mediana de índice de masa corporal de 31 kg / m2 (rango 22-51). La mediana de tiempo entre el intento previo de reparación quirúrgica y la cirugía del gracilis fue de 7 meses (rango 3-17). El número de reparaciones previamente intentadas fue: 1-2 (n = 8), 3-4 (n = 9), y >4 (n = 5). El intento de reparación quirúrgica más reciente fue el colgajo de avance rectal (n = 7), el colgajo transperineal +/- Martius (n = 4), la episioproctotomía (n = 3), la reparación transvaginal (n = 2) y otros (n = 6). Todos los pacientes tenían derivación fecal en el momento de la cirugía gracilis. La infección del sitio quirúrgico posoperatorio a los 30 días en el sitio del injerto / donante fue del 32% (n = 7). Con una mediana de seguimiento de 22 meses (rango 2-62), el cierre de la fístula fue del 59% (n = 13). La interposición de Gracilis fue exitosa en todos los pacientes con enfermedad inflamatoria intestinal.LIMITACIONES:Carácter retrospectivo de los datos.CONCLUSIONES:La interposición de Gracilis es una técnica quirúrgica eficaz para el cierre reoperatorio de la fístula rectovaginal. Se debe asesorar a los pacientes sobre la posibilidad de infección del sitio del injerto / donante. Consulte Video Resumen en http://links.lww.com/DCR/B763 . (Traducción-Dr. Ingrid Melo ).

Predictors of outcome for treatment of enterovaginal fistula : Therapeutical strategies for treatment.

BACKGROUND: Enterovaginal fistulas represent a serious complication of various diseases and therapeutic procedures, often associated with complicated clinical courses and massive impairment of quality of life. As underlying conditions and procedures are multifarious, therapeutic approaches are challenging and have to be tailored individually. As the therapeutic management is complex and individualized, multiple surgical interventions might be necessary. METHODS: The aim of this study was to identify possible predictors for outcome in the treatment enterovaginal fistula patients. The study was realized as a retrospective analysis. Ninety-two patients treated with enterovaginal fistulas between 2004 and 2016 were analyzed. Patient characteristics, therapeutic data, and endoscopic findings were stratified according to etiology, closure rate and time, as well as recurrence of fistula. Main outcome measure was the overall rate of fistula closure. RESULTS: Overall therapeutic success rate was 67.4%. Postoperatively derived fistulas were most frequent (40.2%), mainly after rectal surgery (59.5%). Postoperative and non-IBD-inflammation associated fistulas had better outcome than IBD-, radiotherapy-, and tumor-related fistulas (p = 0.001). Successful fistula closure was observed more frequently after radical surgical interventions, best results observed after transabdominal surgery (p < 0.001). Fistula recurrence was also less frequently observed after radical surgical therapies (p = 0.029). A temporary stoma was associated with higher incidence of fistula closure (p = 0.013) and lower incidence of fistula recurrence (p = 0.042) in the postoperative subgroup, as well as shortened therapy period in all groups (p = 0.031). CONCLUSION: Enterovaginal fistulas are a result of various etiologies, and treatment should be adjusted accordingly. A very sustainable, rapid, and persistent therapeutic success can be expected after radical surgical approaches with temporary diverting stoma. This is especially true for postoperatively derived fistulas.

Conservative surgery versus colorectal resection for endometriosis with rectal involvement: a systematic review and meta-analysis of surgical and long-term outcomes.

PURPOSE: The optimal surgical approach for removal of colorectal endometrial deposits is unclear. Shaving and discoid excision of colorectal deposits allow organ preservation but risk recurrence with associated functional issues and re-operation. Formal resection risks potential higher complications but may be associated with lower recurrence rates. This meta-analysis compares peri-operative and long-term outcomes between conservative surgery (shaving and disc excision) versus formal colorectal resection. METHODS: The study was registered with PROSPERO. A systematic search was performed on PubMed and EMBASE databases. All comparative studies examining surgical outcomes in patients that underwent conservative surgery versus colorectal resection for rectal endometrial deposits were included. The two main groups (conservative versus resection) were compared in three main blocks of variables including group comparability, operative outcomes and long-term outcomes. RESULTS: Seventeen studies including 2861 patients were analysed with patients subdivided by procedure: colorectal resection (n = 1389), shaving (n = 703) and discoid excision (n = 742). When formal colorectal resection was compared to conservative surgery there was lower risk of recurrence (p = 0.002), comparable functional outcomes (minor LARS, p = 0.30, major LARS, p = 0.54), similar rates of postoperative leaks (p = 0.22), pelvic abscesses (p = 0.18) and rectovaginal fistula (p = 0.92). On subgroup analysis, shaving had the highest recurrence rate (p = 0.0007), however a lower rate of stoma formation (p < 0.00001) and rectal stenosis (p = 0.01). Discoid excision and formal resection were comparable. CONCLUSION: Colorectal resection has a significantly lower recurrence rate compared to shaving. There is no difference in complications or functional outcomes between discoid excision and formal resection and both have similar recurrence rates.

Gracilis muscle transposition in complex anorectal fistulas of diverse types and etiologies: long-term results of 60 cases.

PURPOSE: Complex fistulas often require several attempts at repair and continue to be a challenging task for the surgeon, but above all, a major burden for the affected patient. This study is aimed at evaluating the potential of gracilis muscle transposition (GMT) as a therapeutic option for complex fistulas of diverse etiologies. METHODS: A retrospective study was conducted over a period of 16 years with a total of 60 patients (mean age 50 years). All were treated for complex fistula with GMT at St. Josef's Hospital in Regensburg, Germany. Follow-up data were collected and analyzed using a prospective database and telephone interview. Success was defined as the absence of fistula. RESULTS: A total of 60 patients (44 women, 16 men; mean age 50 years, range 24-82 years) were reviewed from January 2005 to June 2021. Primary fistula closure after GMT was achieved in 20 patients (33%) and 19 required further interventions for final healing. Overall healing rate was 65%. Fistula type was heterogeneous, with a dominant subgroup of 35 rectovaginal fistulas. Etiologies of the fistulas were irradiation, abscesses, obstetric injury, and iatrogenic/unknown, and 98% of patients had had previous unsuccessful repair attempts (mean 3.6, range 1-15). In 60% of patients with a stoma (all patients had a stoma, 60/60), stoma closure could be performed after successful fistula closure. Mean follow-up after surgery was 35.9 months (range 1-187 months). No severe intraoperative complications occurred. Postoperative complications were observed in 25%: wound healing disorders (n = 6), gracilis necroses (n = 3), incisional hernia (n = 2), scar tissue pain (n = 2), suture granuloma (n = 1), and osteomyelitis (n = 1). In 3 patients, a second gracilis transposition was performed due to fistula recurrence (n = 2) or fecal incontinence (n = 1). CONCLUSION: Based on the authors' experience, GMT is an effective therapeutic option for the treatment of complex fistulas when other therapeutic attempts have failed and should therefore be considered earlier in the treatment process. It should be seen as the main but not the only step, as additional procedures may be required for complete closure in some cases.

What are the outcomes in patients referred to a tertiary referral centre for Crohn's rectovaginal fistula surgery?

AIM: Rectovaginal fistulas in patients with Crohn's disease are challenging to manage, and surgical treatment remains the best option for achieving permanent closure of the fistula. Biologicals are now used routinely for patients with Crohn's disease. The aim of this study was to investigate the surgical procedures used by us to treat rectovaginal fistula in patients with Crohn's disease in the era of biologicals. METHOD: Patients with Crohn's disease who underwent surgery for a rectovaginal fistula between 2010 and 2020 were included in this retrospective study and were identified from a prospectively maintained institutional database. Collected variables included demographics, perioperative and operative variables and data regarding medications used. Success of the procedure was defined as no symptoms at least 6 months after definitive repair and/or stoma closure. RESULTS: Twenty patients (out of 80 referred for evaluation) underwent surgery with intent to close the fistula and had at least 6 months of follow-up. Mean age was 44 ± 12 years with a median follow-up duration of 33 months (range 6-130 months). Forty per cent of the patients had a history of at least two surgeries to close the fistula. The overall healing rate was 70% (14/20). The most performed procedure was a transanal rectal advancement flap (7/20), with a success rate of 85%. CONCLUSION: Rectovaginal fistula in Crohn's disease is difficult to cure; according to our results almost half of these patients have multiple surgeries due to recurrence. Multiple procedures may be offered for this challenging problem in motivated patients. Perioperative diversion should be strongly considered.

Gracilis muscle interposition for complex perineal fistulas: A systematic review and meta-analysis of the literature.

AIM: Complex perineal fistulas (CPFs) are among the most challenging problems in colorectal practice. Various procedures have been used to treat CPFs, with none being a panacea. Our study aimed to assess the overall success and complication rates after gracilis muscle interposition in patients with CPF. METHOD: PubMed, Scopus and Google Scholar databases were systematically searched until January 2022 according to PRISMA 2020 guidelines. Studies including children <18 years or <10 patients were excluded, as well as reviews, duplicate or animal studies, studies with poor documentation (no report of success rate) and non-English text. An open-source, cross-platform software for advanced meta-analysis openMeta [Analyst]™ version 12.11.14 and Cochrane Review Manager 5.4® were used to conduct the meta-analysis of data. RESULTS: Twenty-five studies published between 2002 and 2021 were identified. The studies included 658 patients (409 women). Most patients had rectovaginal (50.7%) or rectourethral fistulas (33.7%). The most common causes of CPF were pelvic surgery (29.4%) and inflammatory bowel disease (25.2%). A history of radiotherapy was reported in approximately 18% of the patients. 498 (75.7%) patients with CPF achieved complete healing after gracilis muscle interposition. The weighted mean rate of success of the gracilis interposition procedure was 79.4% (95% CI 73.8%-85%, I2  = 75.3%), the weighted mean short-term complication rate was 25.7% (95% CI 18.1-33.2, I2  = 84.1%) and the weighted mean rate for 30-day reoperation was 3.6% (95% CI 1.6-5.6, I2  = 42%). The weighted mean rate of fistula recurrence was 16.7% (95% CI 11%-22.3%, I2  = 61%). CONCLUSION: The gracilis muscle interposition technique is a viable treatment option for CPF. Surgeons should be familiar with indications and techniques to offer it as an option for patients. Given the relatively infrequent use of the operation, referral rather than performance of graciloplasty is an acceptable option.

Predictors and outcomes of surgical repair of obstetric fistula at Mekelle Hamlin Fistula Center, Northern Ethiopia.

BACKGROUND: Obstetric fistula is a medical condition that involves an opening between vagina and bladder or vagina and rectum. From 2010 to 2013, on average, around 2000 women each year had surgery for obstetric fistula in Ethiopia. The success and failure rate of obstetric fistula repair varies from center to center and is determined by many factors. Thus, this study aimed to assess the predictors and outcomes of surgical repair of obstetric fistula at Mekelle Hamlin Fistula Center (MHFC). METHODS: A retrospective reviewed medical records of 328 patients with obstetric fistula were carried out at MHFC. Multivariable logistics regression analysis was conducted, a significant association was declared when the p-value was less than 0.05, and the strength of the association was determined by computing the odds ratio at 95% CI. The analysis was done using SPSS version 24. RESULTS: Obstetrics fistula patients who had formal education were 13% more likely to be successfully repaired than obstetrics fistula patients who had no formal education. Additionally, obstetrics fistula patients who had a live birth were 32.325 (exp (ß) = 32.325) times more likely to have had a successful repair than those who had a stillbirth. CONCLUSION: Fistula closure was achieved in 89.3% of cases. The success rate for VVF (vesico-vaginal fistula) and RVF (recto-vaginal fistula) surgical repair was 86.9% and 100% respectively, which is higher than the WHO target. Body mass index between 18.5-24.9 kg/m2, formal education, antibiotic use, live birth, large fistula size, and home and cesarean delivery were predictors of successful closure of obstetric fistula.

Surgical management of rectovaginal fistula after stapled transanal rectal resection for prolapsed hemorrhoids.

INTRODUCTION AND HYPOTHESIS: Rectovaginal fistula is an epithelium-lined direct communication route between the vagina and the rectum. The gold standard of fistula management is surgical treatment. Rectovaginal fistula after stapled transanal rectal resection (STARR) may be challenging to treat, due to the extensive scarring, the local ischemia, and the risk of rectal stenosis. We aimed to present a case of iatrogenic rectovaginal fistula after STARR that was successfully treated with a transvaginal primary layered repair and bowel diversion. METHODS: A 38-year-old woman was referred to our division for continuous fecal discharge through her vagina that developed a few days after she had a STARR for prolapsed hemorrhoids. Clinical examination revealed a 2.5 cm-wide direct communication between the vagina and rectum. After proper counseling, the patient was admitted to transvaginal layered repair and temporary laparoscopic bowel diversion RESULTS: No surgical complications were observed. The patient was successfully discharged home on postoperative day 3. Bowel diversion was reversed after 2 months. At the current follow-up (6 months), the patient is asymptomatic and without recurrence. CONCLUSIONS: The procedure was successful in obtaining anatomical repair and relieving symptoms. This approach represents a valid procedure for the surgical management of this severe condition.

Excision of Deep Rectovaginal Endometriosis Nodules with Large Infiltration of Both Rectum and Vagina: What Is a Reasonable Rate of Preventive Stoma? A Comparative Study.

STUDY OBJECTIVE: To compare postoperative complications and rectovaginal fistula rate in women undergoing excision of large rectovaginal endometriosis requiring concomitant excision of rectum and vagina during 2 time periods with differing policies for preventive stoma confection. DESIGN: Retrospective before-and-after comparative cohort study on data prospectively recorded in a database. Patients managed from September 2018 to March 2020 (first period) were compared with those managed from April 2020 to June 2022 (second period). SETTING: Endometriosis Institute. PATIENTS: One hundred sixty-eight patients presenting with deep endometriosis infiltrating the rectum and vagina, with lesions more than 3 cm in diameter during 2 consecutive time periods with differing policies regarding use of preventive stoma. INTERVENTIONS: Rectal disc excision or colorectal resection, concomitantly with large vaginal excision. MEASUREMENTS AND MAIN RESULTS: A total of 87 and 81 women received surgery during the first and the second period, respectively, during which the rate of preventive stoma was, respectively, 32.2% and 8.6%. Deep rectovaginal nodule characteristics were comparable. The mean height (SD) of rectal sutures after disc excision and colorectal resection were, respectively, 6.5 cm (2.3 cm) and 7.2 cm (3.8 cm). Rectovaginal fistula was recorded in 17 patients, corresponding to an overall rate of 10.1%. The rates of rectovaginal fistula in the group of patients with and without preventive stoma, regardless of the period in which surgery was performed, were 11.4% and 9.8%, respectively (p = .76). The rates of fistula recorded during the first and the second period were, respectively, 9.2% and 11.1% (p = .80), and that of overall early main complications were 31% and 29.6% (p = .84). Regression logistic model identified an independent relationship between smoking and rectovaginal fistula (adjusted odds ratio [OR] 3.9, 95% confidence interval [CI] 1.1-14) after adjustment for the period (adjusted OR 1.4, 95% CI 0.4-4.9 related to the second period), stoma confection (adjusted OR 1.8, 95% CI 0.5-7.1 related to stoma confection), robotic surgery (adjusted OR 1.7, 95% CI 0.3-10.1 related to robotic assistance), and type of rectal surgery (adjusted OR 0.4, 95% CI 0.1-1.4 related to disc excision when compared with colorectal resection). CONCLUSION: No statistically significant differences were found concerning risk of rectovaginal fistula in women with rectovaginal endometriosis requiring large rectal and vaginal excision after a decision to no longer routinely perform preventive stoma.

"A Space Odyssey" on Laparoscopic Segmental Rectosigmoid Resection for Deep Endometriosis: A Seventeen-year Retrospective Analysis of Outcomes and Postoperative Complications among 3050 Patients Treated in a Referral Center.

STUDY OBJECTIVE: To evaluate the feasibility of laparoscopic rectosigmoid resection for bowel endometriosis (RSE), reporting surgical and short-term postoperative outcomes in a consecutive large series of patients. DESIGN: A retrospective cohort study. SETTING: Third-level national referral center for deep endometriosis (DE). PATIENTS: 3050 patients with symptomatic RSE requiring surgical treatment. INTERVENTIONS: Nerve-sparing laparoscopic resection for RSE perfomed by a multidisciplinary team. After collecting intraoperative surgical characteristics, postoperative complications were collected by evaluating the risk factors associated with their onset. MEASUREMENTS AND MAIN RESULTS: Clavien-Dindo IIIb postoperative complications were noted in 13.1% of patients, with anastomotic leakage and rectovaginal fistula accounting for 3.0% and 1.9%, respectively. Postoperative bladder impairment was observed in 13.9% of patients during hospital discharge but spontaneously decreased to 4.5% at the first evaluation after 30 days, alongside a statistically significant change towards global symptom improvement. Multivariate analyses were done to identify the risk factors for segmental bowel resection in terms of occurrence of postoperative major complications. Ultralow (≤5 cm from the anal verge), low rectal anastomosis (<8 cm, >5 cm), parametrectomy, vaginal resection, and previous surgeries seemed more related to anastomotic leakage, rectovaginal fistula, and bladder retention. CONCLUSIONS: Laparoscopic rectosigmoid resection for RSE seems an effective and feasible procedure. The surgical complication rate is not negligible but could be reduced by implementing a multidisciplinary approach, an endless improvement in nerve-sparing techniques and surgical anatomy, as well as technological enhancements. Real future challenges will be to reduce the time for the first diagnosis of DE and the likelihood of surgical indications.

What is the best surgical option after failure of graciloplasty in patients with recurrent rectovaginal fistula? A study of 19 consecutive patients.

BACKGROUND: Management of recurrent rectovaginal fistula (rRVF) remains challenging despite the good results of graciloplasty reported in the literature. However, little is known about how to avoid a permanent stoma if graciloplasty fails. The aim of our study was to report the management of rRVF after failure of graciloplasty. METHODS: A retrospective study was performed on consecutive patients with rRVF after failure of graciloplasty treated at our institution in January 2005-December 2021. RESULTS: There were 19 patients, with a median age at graciloplasty of 39 years (range 25-64 years). Etiologies of RVF were Crohn's disease (CD) (n = 10), postoperative (n = 5), post-obstetrical (n = 3), and unknown (n = 1). After failure of graciloplasty, 45 new procedures were performed, all of them with a covering stoma: trans-anal repairs (n = 31), delayed colo-anal anastomosis (DCAA) (n = 4), biological mesh interposition (n = 3), second graciloplasty (n = 3), stoma only (n = 2) and redo ileal pouch-anal anastomosis (IPAA) (n = 2). One patient was not re-operated on and instead treated medically for CD. After a mean follow-up of 63 ± 49 months, success (i.e., absence of stoma or RVF) was obtained in 11 patients (58%): 4/4 DCAA (100%), 5/31 after local repair (16%), 1 after stoma creation alone (50%) and 1 after redo IPAA (50%). Second graciloplasty and biologic mesh interposition all failed. All 8 patients with failed intervention had CD. CONCLUSIONS: In cases of rRVF after failed graciloplasty, reoperation is possible, although the chance of success is relatively low. The best results were obtained with DCAA. CD is a predictor of poor outcome.

Use of teduglutide for short bowel syndrome and Crohn's disease in a patient treated with ustekinumab and vedolizumab dual biologic therapy.

Surgery in Crohn's disease may be the cause of short bowel syndrome that may lead to kidney dysfunction. Dual biologic therapy is rarely needed to control activity. We present a case of a 61-year-old steroid dependent (A2L1B3p) female who had undergone surgery on three occasions: ileocecal resection (resection of 15 cm of terminal ileum); resection of right and left colon up to sigmoid; proctectomy with intersphincteric resection along with ileostomy due to a rectovaginal fistula. She had been previously treated with prednisone, azathioprine, methotrexate, infliximab and adalimumab but the treatment was discontinued owing to adverse effects. Vedolizumab was started, showing good control of the luminal activity but the rectovaginal fistula recurred. Treatment changed to ustekinumab, the fistula activity was controlled but the mucosa activity recurred. 11 months after commencing with ustekinumab, vedolizumab was added to the treatment and complete remission was achieved for three years. Simultaneously, the patient developed renal dysfunction derived from the short bowel syndrome that led to chronic kidney failure. In the face of potential renal replacement therapy, a new therapy with 2.5 mg/sc/d teduglutide was started achieving stable figures of creatinine and normalization of the glomerular filtration rate.
