Long-term functional outcomes following non-radiated urethrovaginal fistula repair.

OBJECTIVE: To review long-term functional outcomes after urethrovaginal fistula (UVF) repair. MATERIALS AND METHODS: Following IRB approval, women who underwent transvaginal non-irradiated UVF repair with minimum 6-month follow-up were reviewed. Surgical outcomes were assessed by validated questionnaires: UDI-6, IIQ-7, FSFI and visual analogue scale for QoL. Two groups were compared: (1) synthetic sling-related versus (2) non-sling-related UVF. Descriptive statistics were applied with p < 0.05 for significance. RESULTS: From 1996 to 2013, 18 patients underwent UVF repair, with a mean age of 46 years (range 20-66), BMI 29 (range 21-42) and mean follow-up at 52 months (range 9-142). Overall repair success rate was 95%. Prior failed UVF repair was recorded in 11 women (61%). Statistical differences noted for Q4: 1.9 versus 0.8 (p = 0.03) and Q5: 1.3 versus 0 (p = 0.02) and VAS between the two groups, favoring the non-sling group; 1.5 (0.6) versus 5 (4) (p = 0.05). No differences in IIQ-7 were noted between the two groups (p = 0.09). Of the 18 patients, 5 remained sexually active and of those, 2 responded to FSFI (40%) with low scores. Reoperation rate was 33% (6 women) with 3 requiring periurethral-bulking agent for recurrent SUI, 2 transurethral laser for residual urethral sling mesh strands and 1 urethral dilation. CONCLUSION: This large contemporary series of non-radiated UVF indicates a satisfactory outcome in UVF closure repair at a mean 4- to 5-year long-term follow-up, with the synthetic sling-related group performing worse.

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

AIM: 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). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Overcoming phase 1 delays: the critical component of obstetric fistula prevention programs in resource-poor countries.

BACKGROUND: An obstetric fistula is a traumatic childbirth injury that occurs when labor is obstructed and delivery is delayed. Prolonged obstructed labor leads to the destruction of the tissues that normally separate the bladder from the vagina and creates a passageway (fistula) through which urine leaks continuously. Women with a fistula become social outcasts. Universal high-quality maternity care has eliminated the obstetric fistula in wealthy countries, but millions of women in resource-poor nations still experience prolonged labor and tens of thousands of new fistula sufferers are added to the millions of pre-existing cases each year. This article discusses fistula prevention in developing countries, focusing on the factors which delay treatment of prolonged labor. DISCUSSION: Obstetric fistulas can be prevented through contraception, avoiding obstructed labor, or improving outcomes for women who develop obstructed labor. Contraception is of little use to women who are already pregnant and there is no reliable screening test to predict obstruction in advance of labor. Improving the outcome of obstructed labor depends on prompt diagnosis and timely intervention (usually by cesarean section). Because obstetric fistulas are caused by tissue compression, the time interval from obstruction to delivery is critical. This time interval is often extended by delays in deciding to seek care, delays in arriving at a hospital, and delays in accessing treatment after arrival. Communities can reasonably demand that governments and healthcare institutions improve the second (transportation) and third (treatment) phases of delay. Initial delays in seeking hospital care are caused by failure to recognize that labor is prolonged, confusion concerning what should be done (often the result of competing therapeutic pathways), lack of women's agency, unfamiliarity with and fear of hospitals and the treatments they offer (especially surgery), and economic constraints on access to care. SUMMARY: Women in resource-poor countries will use institutional obstetric care when the services provided are valued more than the competing choices offered by a pluralistic medical system. The key to obstetric fistula prevention is competent obstetrical care delivered respectfully, promptly, and at affordable cost. The utilization of these services is driven largely by trust.

Urodynamic findings in patients with urogenital fistulae.

OBJECTIVE: To assess the feasibility of carrying out a urodynamic investigation in patients with a urogenital fistula and to establish the incidence of abnormal lower urinary tract function in such patients. PATIENTS AND METHODS: Of 38 patients referred within the last 3 years with a diagnosis of lower urinary tract genital fistula, 30 were investigated by dual-channel subtracted cystometry before surgical treatment of their fistula; in addition, urethral pressure profilometry was carried out in 19 patients. Fourteen of the patients had fistulae into the vaginal vault; the urodynamic findings in this subgroup were compared with those of 12 patients with bladder neck and urethrovaginal fistulae. Twenty-six of the 30 patients underwent surgical treatment and 24 (92%) were cured anatomically by their first procedure. Ten patients complained of residual lower urinary tract symptoms and were re-investigated. RESULTS: Of the 38 patients, 47% had genuine stress incontinence, 40% showed systolic detrusor instability and 17% impaired bladder compliance. Half had evidence of voiding dysfunction; most appeared to be of a hypotonic detrusor type, although four cases showed an obstructive pattern. Fifteen patients had more than one abnormality and only five (17%) had entirely normal urodynamic findings. The overall incidence of functional abnormality was highest in the patients with urethral or bladder neck fistulae, with only one showing entirely normal urodynamic findings. Genuine stress incontinence was found more than twice as often associated with urethral or bladder neck fistulae and detrusor instability was also more common in this group. Voiding dysfunction of both hypotonic and obstructive types was found equally in the two groups. After surgical treatment, most patients became continent and free from lower urinary tract symptoms, although one complained of residual stress incontinence and nine of urgency or urge incontinence. Of the latter, six were found to have detrusor instability, one after repair of vault fistula, three after urethral or bladder neck fistulae and the other two after mid-vaginal fistulae. CONCLUSION: There is a high incidence of abnormal lower urinary tract function in patients with urogenital fistulae. Patients with urethral or bladder neck fistulae had a higher incidence of both detrusor instability and genuine stress incontinence than those with fistulae into the vaginal vault. Many of these abnormalities appear to resolve after successful repair of the fistula, although detrusor instability may persist and require further treatment in some women. These findings are relevant to the counselling of patients before repair and may be of medico-legal significance.

Clinical course after transanal advancement flap repair of perianal fistula in patients with Crohn's disease.

A total of 36 rectal advancement flap repairs were performed in 32 patients with perianal Crohn's disease. There were 12 anovaginal and 20 trans-sphincteric fistulas. Patients were followed prospectively for a mean of 19.5 months to evaluate postoperative recurrence rate. The prognostic influence of fistula type, rectal disease, intestinal disease and faecal diversion on recurrence was assessed. Four of 36 repairs showed primary failure, the operated fistula recurred in 11 patients after a median of 7 months, and a new fistula developed in six patients. The fistula recurrence rate was higher in patients with anovaginal fistula or Crohn's colitis but did not correlate with disease activity. Transitory mild incontinence of stool was observed in one patient only. Although rectal advancement flap repair does not cure perianal fistulas in most patients with Crohn's disease, those without Crohn's colitis may have long-term benefit. Short-term improvement of symptoms justifies this simple procedure even in patients with anovaginal fistula.

Twenty-year review of the surgical management of perianal Crohn's disease.

PURPOSE: A retrospective analysis of 48 patients treated over a 20-year period (March 1973-April 1993) was undertaken to assess the results of our practice of early surgical intervention in suppurative complications of perianal Crohn's disease. METHODS: All patients were either seen in the office within the last six months or contacted by phone. RESULTS: The average age of our patients was 30 years at initial diagnosis. Thirty-four patients (71 percent) initially presented with intestinal disease and four (8 percent) with only perianal disease. Thirteen patients (27 percent) initially presented with simultaneous intestinal and perianal disease. The various fistulas at initial presentation included 8 intersphincteric (17 percent), 14 transphincteric (29 percent), 11 complex or multiple (23 percent), 5 rectovaginal (10 percent), and 2 unclassified, for a total of 40 patients. Eight patients (17 percent) presented with only an abscess. Eighty five percent of our patients healed after their first procedure, with an average time to heal of 2.8 months. Thirteen (27 percent) patients had recurrences after initial healing of their wounds. The mean time to recurrence after healing was 5.25 years. Fifty-four percent of our recurrences (7 patients) were treated by incision and drainage of an abscess only. Seven of 13 recurrences healed after the second procedure (54 percent), and 5 of 6 healed after a third procedure (83 percent). Only seven (14 percent) of our patients underwent a proctocolectomy during the study period, through September, 1993. Our overall probability of avoiding proctectomy and healing perineal wounds of 86 percent is consistent with published literature. CONCLUSIONS: Early aggressive surgical management of suppurative complications of perianal Crohn's disease before complex management problems ensue results in a high incidence of healing and a low risk of subsequent proctectomy.

The treatment of internal fistulae that complicate diverticular disease of the sigmoid colon by laparoscopically assisted colectomy.

Seven patients with internal fistulae complicating colonic diverticular disease were treated by laparoscopic assisted colectomy over a 24-month period. Prospective review of these patients was carried out to ascertain efficacy of the treatment. No intraoperative complications were encountered and return of gastrointestinal function was apparent within two days in all cases. Postoperative hospital stay was limited to an average of 4.7 days. No long-term complication or fistula recurrence has been noted in the mean 11-month follow-up period. This study indicates laparoscopic assisted colectomy is an effective means of treatment for diverticular fistulae.

Anorectal malformations.

The posterior sagittal approach was used to treat 792 patients with anorectal malformations. From these, 387 cases were evaluated 6 months to 13 years later. Voluntary bowel movements were present in 74.3% of the entire series. When distributed by diagnosis, the percentages varied: 100% in patients with rectal atresia and perineal fistula; 93.2% in those with vestibular fistula; 80.9% in those with bulbar fistula; 71.1% in those with cloacas; 66.7% in those with prostatic fistula, and 15.8% in those with bladder-neck fistula. Soiling was present in 57% of all cases. Patients with voluntary bowel movements and no soiling were classified as totally continent; 40.8% of the series belong to this group. Distributed by diagnosis, it varied from 100% in cases with rectal atresia or perineal fistula, 65.9% in those with vestibular fistula, 34% in those with bulbar fistula, 31.6% in those with cloacas, 26.3% in those with prostatic fistula; none of the patients with vaginal fistula or bladder-neck fistula was totally continent. Constipation was detected in 43.1% of all patients, and was more frequent in those with simple defects. Urinary incontinence was found in 19% of patients with cloacas who had a common channel shorter than 3 cm, and in 68.8% of the patients who had longer common channels. Other patients suffered from urinary incontinence only when they had an absent sacrum or other severe bladder or urethral congenital defects. An accurate diagnosis and evaluation of the sacrum allows us to establish, with reasonable accuracy, functional prognosis in most children. Those with functional disorders must be treated properly medically, to improve their quality of life.
