Persistent perineal sinus following proctocolectomy in the inflammatory bowel disease patient.

Prolonged perineal wound healing following proctocolectomy in patients with inflammatory bowel disease (IBD) is a frustrating result for the medical team and patients who were hoping for improved quality of life. Prolonged healing, which lasts more than 6 months following proctocolectomy, is termed persistent perineal sinus (PPS) and typically necessitates further surgical management. Healing of the PPS is difficult due to the resulting "dead space" following proctocolectomy, necessitating the need to fill the void with viable tissue in an area with anatomic constraints. Here we provide a narrative review and comprehensively address the incidence, pathogenesis, and clinical and operative management of a PPS in patients with IBD following proctocolectomy. Operative methods discussed include surgical debridement, flap closure of the perineum, omental flap closure, and gracilis muscle transposition. It is necessary to further investigate and establish a gold standard of care for these patients.

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

PurposeComplex 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.MethodsA 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.ResultsA 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).ConclusionBased 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.

Surgical treatment of rectovaginal fistulas (systematic literature review)

Despite the large number of available surgical interventions aimed at the treatment of rectovaginal fistulas, the results of their use remain extremely disappointing, associated with the high recurrence rate of the disease reaching 80 %, as well as the lack of a single tactic to minimize the risk of anal incontinence and the need for colostomy. Objective: to conduct a systematic literature review in order to summarize information related to the rectovaginal fistulas surgery. The systematic review includes the results of an analysis of 97 clinical trials selected from 756 publications found in databases. Inclusion criteria: a full-text article, the presence of at least 5 patients in the study, as well as data on the outcome of surgery. Clinical trials with different surgical treatments were identified and classified into the following categories: elimination of the rectovaginal septal defect with a displaced flap (rectal and vaginal); Martius surgery; gracilis muscle transposition; transperineal procedure; abdominal procedure including endoscopic and laparoscopic methods; use of biological or biocompatible materials. Treatment outcomes vary significantly from 0 % to > 80 %. None of the studies were randomized. Due to the low quality of the identified studies, comparison of results and meta-analysis conduction were not possible. Conclusion: as a result of the systematic review, data for the analysis and development of any strategic and tactical algorithms for the treatment of RVF were not obtained. The most important questions still remain open: what and when surgical method to choose, is it necessary to form a disconnecting stoma?

What is the best method of rectovaginal fistula repair? A 25-year single-center experience.

The surgical treatment of rectovaginal fistula (RVF) remains challenging and there is a lack of data to demonstrate the best, single procedure. The aim of this study was to assess the results of different surgical operations for rectovaginal fistula. Patients with RVF who underwent surgical repair between 1992 and 2017 at a single, tertiary care center were included. Twenty different procedures were performed including: primary closure, closure with sphincter repair, flap repairs, plug/fibrin/mesh repair, examination under anesthesia (EUA) ± seton placement, abdominal resections with and without diversion and ileostomy takedown, gracilis muscle transposition, fistulotomy/ligation of intersphincteric fistula tract. All patients with RVF due to diverticulitis and patients without complete data from paper charting were excluded. Success was defined based on the absence of symptoms related to RVF and absence of diverting stoma at 6months. One hundred twenty-four women were analyzed. The median age was 45 (range 18-84) years. Median follow-up time from the last procedure was 6months (range 0-203months). The total number of patients considered successfully treated at the end of their treatment was 91 (91/124, 73.4%). When considering all procedures (n = 255), the success rate for flap procedures was 57.9% (22/38), followed by abdominal resections with and without proximal diversion and ileostomy takedown (16/29, 55.2%) and primary closure with sphincter repair (17/32, 53.1%) while fistula plug, and fibrin glue had among the lowest success rates (4/22, 18.2%). The highest success rate was observed among patients whose RVF etiology was due to malignancy (11/16, 68.8%) followed by unknown (8/14, 57%) and iatrogenic (21/48, 43.8%) causes. Local procedures such as mucosal flap or primary closure and sphincteroplasty are associated with a high success rate should be considered in patients with low-lying, simple RVF. Abdominal resections with and without proximal diversions and ileostomy takedown have a relatively high success rate in selected patients. The low success rate of fibrin glue and fistula plugs demonstrates their low efficacy in RVF; thus, these procedures should be avoided in the treatment algorithm.

Clinical outcome and quality of life after gracilis muscle transposition for fistula closure over a 10-year period.

Gracilis muscle transposition (GMT) is an established surgical technique in the treatment of anorectal fistulas and fistulas to the vagina and the urinary system when previous closure options have failed. There is little evidence on the success rate of this procedure in the long term. This is a follow-up study on all patients undergoing GMT over a 10-year period at a tertiary referral center for complex fistulas. Postoperative function and quality of life were evaluated by standardized questionnaires (Wexner score, Fecal Incontinence Quality of Life Score (FIQL), SF-12 and a brief questionnaire designed for this study). Sexual function was evaluated by the Female Sexual Function Index (FSFI) and the International Index of Erectile Function. Forty-seven gracilis muscle transpositions (GMT) in 46 patients were performed. Most treated patients had (neo-)-rectovaginal fistulas (n = 29). An overall fistula closure was achieved in 34 of 46 patients (74%): in 25 cases primarily by GMT (53%) and in nine patients with persistent or recurrent fistula by additional surgical procedures. A clinically apparent relapse occurred on average 276 days (median: 180 days) after GMT (mean follow-up 73.4 months). GMT in our hands has a primary closure rate of 53%, and after further procedures, this rises to 74%. Fecal continence is impaired in patients having undergone GMT. The overall quality of life in patients after GMT is only slightly impaired, and sexual function is severely impaired in female patients.

Gracilis muscle transposition for treatment of recurrent anovaginal, rectovaginal, rectourethral, and pouch\u2013vaginal fistulas in patients with inflammatory bowel disease

BackgroundThe aim of this study was to evaluate the effectiveness of gracilis muscle transposition (GMT) to treat recurrent anovaginal, rectovaginal, rectourethral, and pouch–vaginal fistulas in patients with inflammatory bowel disease (IBD).MethodsA retrospective study was conducted in patients with IBD who had GMT performed by a single surgeon between 2000 and 2018. Follow-up data regarding healing rate, complications, additional procedures, and stoma closure rate was collected.ResultsA total of 30 women and 2 men had GMT. In all patients fistula was associated with Crohn's disease. In 1 female patient, contralateral gracilis transposition was required after a failed attempt at repair. The primary healing rate was 47% (15/32) and the definitive healing rate (healed by the time of data collection and after secondary procedures) was 71% (23/32). Additional surgical procedures due to fistula persistence or recurrence were performed on 17 patients (53%).At least 7 patients (21%) suffered complications including one wound infection with ischemia of the gracilis muscle. Stoma closure was successful in 18 of 31 cases of patients with stoma (58% of the patients).ConclusionsGMT for the treatment of recurrent and complex anorectal fistulas in patients with IBD patient is eventually successful in almost 2/3 of patients.

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

PurposeRectovaginal 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.MethodsBetween 1998 and 2016, 92 patients underwent 128 operations for rectovaginal fistula. Prospectively collected data were recorded, and a retrospective review was conducted.ResultsThe 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).ConclusionRadiation 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.

Gracilis muscle transposition for the treatment of recurrent rectovaginal and pouch-vaginal fistula: is Crohn's disease a risk factor for failure? A prospective cohort study.

The surgical management of rectovaginal fistulae associated with Crohn's disease is often frustrated by poor results regardless of the different techniques. The outcomes of the gracilis muscle transposition (GMT) for the treatment of recurrent Crohn's-associated fistulae are still debated. The aim of the study is to determine whether the success rate of GMT is similar in Crohn's disease patients and in a control group. All patients undergoing GMT for rectovaginal or pouch-vaginal fistula were collected from a prospectively maintained database (2005-2016). The primary study outcome was the comparison of the success rate of GMT in Crohn's disease and control group patients. Twenty-one patients with a rectovaginal fistula due to Crohn's disease (8, 38.1%) or other etiologies (13, 61.9%) were included. The groups had similar characteristics and postoperative outcomes. After a median follow-up time of 81 and 57months (p 0.34), the success rate of GMT was 75% in patients with Crohn's disease and 68.4% in control group (p 0.6). The median time to recurrence was 3.5months (1-12). The success rate in patients who had more than two previous attempts of repair was lower regardless of the etiology (50 vs 79.4%, p 0.1). GMT is associated with a high success rate, especially in Crohn's disease-related rectovaginal fistula. In consideration of the low morbidity rate and the fact that an increasing number of previous local operations might be associated with failure, the procedure should be considered as a first line of treatment for recurrent rectovaginal fistulae.

Choice of different tissue flaps in the treatment of urethro-rectal fistulas associated with urethral strictures

Objective To evaluate the clinical efficacy of different tissue flaps interposition in reconstructing urethra-rectal fistulas associated with posterior urethral strictures. Methods Twenty-nine patients with urethra-rectal fistulas associated with posterior urethral strictures (15 patients after traffic accident trauma, 9 after falling injury, and 5 after pelvic crush injury) were included in this study. Trans-perineal urethral reconstruction and fistula repair with perineal subcutaneous dartos pedicled flap transposition was performed in 15 patients in whom fistulas were near the anus (<5 cm) and the perineal subcutaneous tissues were rich in blood supply. An interposition gracilis muscle flap was placed in 14 patients with fistulas located farther from the anus (≥5cm) or poor perineal local tissue condition. Results After a mean follow-up of 24.5 months (5-67 months), successful repair was achieved in 12 of 15 patients (80.0%) undergoing perineal subcutaneous dartos pedicled flap transposition, and in 11 of 14 patients (78.6%) undergoing gracilis muscle transposition. The overall success rate was 79.3%. No long-term procedure related complications occurred except medial thigh numbness in 1 patient. Conclusions The perineal subcutaneous dartos pedicled flap is suitable for hypervascular and low-positioned urethra-rectal fistulas located less than 5 cm from the anus. For patients with high-positioned fistulas or poor perineal local tissue conditions, the gracilis muscle flap is recommended. The technique of vascularized tissue pedicled flap transposition is essential for urethra-rectal fistula repair. Key words: Urethra-rectal fistula; Urethral stricture; Surgery; Tissue flap

Treatment of rectovaginal fistula with gracilis muscle flap transposition: long-term follow-up.

Rectovaginal fistulas are difficult to treat completely, especially when patients present with a history of multiple surgeries and radiation therapy. We aimed to evaluate the efficacy of gracilis muscle flap transposition to treat rectovaginal fistula. We performed a retrospective chart review of all gracilis muscle transposition cases and other procedures between January 2009 and July 2016. Total 53 cases were reviewed. A total of 11 patients underwent gracilis muscle flap transposition for rectovaginal fistula repair, with 8 patients showing good results without recurrence (total success rate, 72.7%). Comparison of this patient group with patients who had undergone other surgical procedures for rectovaginal fistula repair showed that those who received a gracilis transposition flap had significantly higher average number of previous surgeries (2.18±1.17 vs. 1.1±1.25) and had previously undergone radiotherapy at a significantly higher rate (63.6 vs. 26.2%). Furthermore, none of our patients complained of donor site discomfort. Based on these results, we recommend using the gracilis muscle flap for rectovaginal fistula repair in cases where there is a history of radiotherapy and had surgical failure more than twice.

Gracilis muscle transposition as a workhorse flap for anal incontinence: Quality of life and functional outcome in adults.

Background/Purpose:Anal incontinence is one of the most psychologically and socially debilitating conditions in an otherwise healthy individual. It can lead to social isolation, loss of self-esteem, self-confidence and depression. This study is devoted to the problem of anal incontinence in the adult patients. The aim of our study is to analyse the results of gracilis muscle transposition for anal incontinence and improvement in quality of life (QOL) of patients.Materials and Methods:This was a retrospective study. A total of 18 patients with complaint of anal incontinence were enrolled in this study. All patients were treated with gracilis muscle transposition.Results:All patients are continent, and there is an improvement in their QOL.Conclusion:Gracilis muscle transposition is a good option for patients of anal incontinence who are not treated by non-surgical means.

Management of fourth degree obstetric perineal tear without colostomy using non - stimulated gracilis - our experience over eleven years.

Background:Although gracilis muscle transposition for faecal incontinence has been well-described method, its literature for use in obstetric perineal tear without colostomy is sparse. In this study, we have tried to analyse its use in fourth-degree obstetric perineal tears.Patients and Methods:A total of 30 patients with recto-vaginal fistula with faecal incontinence secondary to obstetric perineal tear were retrospectively studied between February 2003 and May 2014. The recto-vaginal fistula was explored, dissected and identification of sphincters was done using muscle stimulator. Fistula closure was done followed by sphincter repair, vaginal tightening procedure and single gracilis transposition. None of the patients had covering colostomy. Faecal incontinence was assessed pre- and post-operatively by digital rectal examination (single examiner), Park's score and Corman's score in all cases and using barium hold and transperineal ultrasonography, manometric studies in a few cases. The outcome was measured at an average follow-up of 8.8 months (7–24 months).Results:As per Park's score 26 patients had Grade I continence, two had Grade II and two patients had Grade III continence. Corman's score improved from fair to excellent in 26 patients. The patients in whom manometry was performed showed a remarkable rise in both resting and squeeze pressures. Two patients developed post-operative infections in upper 1/3 thigh incision site and three patients at gluteal region scar site.Conclusion:Satisfactory continence following gracilis muscle could be achieved.

The disappointing quality of published studies on operative techniques for rectovaginal fistulas: a blueprint for a prospective multi-institutional study.

Treatment of rectovaginal fistulas is difficult, and many surgical interventions have been developed. The best surgical intervention for the closure of these fistulas is still unclear. A systematic review was performed reporting the outcomes of different surgical techniques for rectovaginal fistulas. Medline (PubMed, Ovid), Embase (Ovid), and The Cochrane Library databases were searched for eligible articles as well as the references of these articles. Two independent reviewers analyzed the search results for eligible articles based on title, abstract, and described results. Any surgical intervention for the closure of rectovaginal fistulas was included. The main outcome was closure rate. Secondary outcomes were quality of life, morbidity, and the effect on sexual functioning. Many articles with different operative techniques were identified and classified in the following categories: advancement flaps (endorectal and endovaginal), transperineal closure, Martius procedure, gracilis muscle transposition, rectal resections, transabdominal closure, mesh repair, plugs, endoscopic repairs, closure with biomaterials, and miscellaneous techniques. Results vary widely with closure rates between 0% and >80%. None of the studies were randomized. Because of the poor quality of the identified studies, the comparison of results and performance of a meta-analysis were not possible.Data regarding the secondary outcomes were mostly unavailable. The major limitation of this review was the limited availability of high-quality prospective studies, making it impossible to perform a meta-analysis. No conclusion about the best surgical intervention for rectovaginal fistulas could be formulated. More large studies of high quality are needed to find the best treatment for rectovaginal fistulas. A design for these high-quality studies was formulated.

Adynamic and dynamic muscle transposition techniques for anal incontinence.

Gracilis muscle transposition is well established in general surgery and has been the main muscle transposition technique for anal incontinence. Dynamization, through a schedule of continuous electrical stimulation, converts the fatigue-prone muscle fibres to a tonic fatigue-resistant morphology with acceptable results in those cases where there is limited sphincter muscle mass. The differences between gluteoplasty and graciloplasty, as well as the techniques and complications of both procedures, are outlined in this review. Overall, these techniques are rarely carried out in specialized units with experience, as there is a high revision and explantation rate.

Treatment of recurrent rectovaginal/pouch-vaginal fistulas by gracilis muscle transposition – a single center experience

Rectovaginal fistulas constitute a serious burden for the affected patient and a major challenge for the attending surgeon. Definitive surgical treatment of the fistula depends on the size and location of the fistula, the underlying disease, and any previous therapies. In regards to complicated recurrent rectovaginal fistulas, transposition of the gracilis muscle is one of the well-established therapeutic options with a success rate of up to 70%. Between 01/2004 and 06/2010, ten patients diagnosed with a recurrent rectovaginal fistula were treated in the surgical department of Klinikum Oldenburg by gracilis muscle transposition; their data were collected and analyzed. Post-operative evaluation was performed using a standardized telephone interview. All patients had a protective stoma. The primary endpoint of assessment was the long-term healing of the fistula following stoma reversal, and the comparison between those who were treated successfully versus those who were not. Over a time span of 6years, ten women with a complicated rectovaginal fistula underwent fistula repair with the gracilis muscle transposition. Patient age ranged from 29 and 64years. There were five rectovaginal fistulas, four pouch-vaginal fistulas, and one anovaginal fistula. The underlying disease was rectal cancer in seven patients, Crohn's disease in one patient, previous complicated gynecologic surgery in one patient, and idiopathic anal fistula in one patient. All seven patients with rectal cancer underwent radiochemotherapy with 50.4Gy (n=6 neo-adjuvant, n=1 adjuvant). All ten patients had previously undergone repair by a different surgical approach while five presented with a second or third recurrence. Post-operative complications were noted in two patients (perineal wound defect, thigh hematoma). Follow-up of the patients ranged from 8 to 60months. Recurrent rectovaginal fistula occurred in four patients. Evaluation of the data failed to identify statistically significant criteria for treatment failure of rectovaginal fistula repair. Our results are similar to previous studies in this area. For the majority of the patients, the gracilis muscle transposition was a long-term effective treatment of recurrent rectovaginal fistulas, however recurrences were noted in 40% of cases. Predictive criteria for treatment failure could not be established.

Salvage irrigation-suction in gracilis muscle repair of complex rectovaginal and rectourethral fistulas

To evaluate the efficacy of gracilis muscle transposition and postoperative salvage irrigation-suction in the treatment of complex rectovaginal fistulas (RVFs) and rectourethral fistulas (RUFs). Between May 2009 and March 2012, 11 female patients with complex RVFs and 8 male patients with RUFs were prospectively enrolled. Gracilis muscle transposition was undertaken in all patients and postoperative wound irrigation-suction was performed in patients with early leakage. Efficacy was assessed in terms of the success rate and surgical complications. SF-36 quality of life (QOL) scores and Wexner fecal incontinence scores were compared before and after surgery. The fistulas healed in 14 patients after gracilis muscle transposition; the initial healing rate was 73.7%. Postoperative leakage occurred and continuous irrigation-suction of wounds was undertaken in 5 patients: 4 healed and 1 failed, and postoperative fecal diversions were performed for the patient whose treatment failed. At a median follow-up of 17 mo, the overall healing rate was 94.7%. Postoperative complications occurred in 4 cases. Significant improvement was observed in the quality outcomes framework scores (P < 0.001) and Wexner fecal incontinence scores (P = 0.002) after the successful healing of complex RVFs or RUFs. There was no significant difference in SF-36 QOL scores between the initial healing group and irrigation-suction-assisted healing group. Gracilis muscle transposition and postoperative salvage wound irrigation-suction gained a high success rate in the treatment of complex RVFs and RUFs. QOL and fecal incontinence were significantly improved after the successful healing of RVFs and RUFs.

Prospective study of gracilis muscle repair of complex rectovaginal fistula and rectourethral fistula

To assess the efficacy and experience of gracilis muscle transposition for complex rectovaginal fistula (RVF) and rectourethral fistula (RUF). Nineteen patients underwent gracilis muscle transposition for complex RVF and RUF from May 2009 to November 2011 in the Beijing Shijitan Hospital and the clinical data were prospectively collected. The success rate and complications were recorded. SF-36 quality of life score, Wexner fecal incontinence score, and female sexual function score before surgery and 6 months after surgery were recorded. In 19 patients, there were 8 males (RUF) and 11 females (RUF). The times of failed attempt repair preoperatively ranged from 0-3 (mean, 1.0). The diameter of the fistula ranged from 0.5-3.0 cm (mean, 1.6), and all fistulas located above the sphincter. The operative time ranged from 145-400 minutes (median, 240). The postoperative hospital stay ranged from 10-39 days (median 21). Early postoperative complications included thigh pain and numbness in 2 cases, leg numbness in 2 cases. No long-term complications were noticed. The follow-up period ranged from 6-35 months (median, 18). The gracilis muscle transposition had a healing rate of 94.7% (18/19). As compared with the preoperative level, Wexner score decreased from 10.0±8.8 to 2.9±5.8, and the continence function improved significantly (P=0.002). Sexual function score of 11 female patients increased from 1.0±1.8 to 4.0±4.0, and the sexual function had a significant improvement after surgery (P=0.022). SF-36 quality of life scores improved significantly (P<0.001). Gracilis muscle transposition for complex rectovaginal fistula and rectourethral fistula has high success rate with mild and rare complications.
