Laparoscopic fistula excision and omentoplasty for high rectovaginal fistulas: a prospective study of 40 patients

AIM: The aim of this study is to prospectively evaluate 40 patients with a high rectovaginal fistula treated by a laparoscopic fistula division and closure, followed by an omentoplasty. PATIENTS AND METHODS: Forty patients with a rectovaginal fistula, between the middle third of the rectum and the posterior vaginal fornix, resulting from different causes (IBD, iatrogenic and birth trauma) were treated by a laparoscopic excision of the fistula and insertion of an omentoplasty in the rectovaginal septum. The patients completed the gastrointestinal quality of life index questionnaire (GIQLI) and the Cleveland Clinic incontinence score (CCIS). All tests were performed at regular intervals after treatment. RESULTS: In 38 (95%) patients with a median age of 53 years (range 33-72), the surgical procedure was feasible. In two patients, the fistula was closed without an omentoplasty, and a diverting stoma was performed. The median follow-up was 28 months (range 10-35). Two patients (5%) developed a recurrent fistula. In one patient, the interposed omentum became necrotic and was successfully treated laparoscopically. In another patient, an abscess developed, which needed drainage procedures. The mean CCIS was 9 (range 7-10) before treatment and 10 (range 7-13) after treatment (p = 0.5 Wilcoxon). The median GIQLI score was 85 (range 34-129) before treatment and 120 (range75-142) after treatment (p = 0.0001, Wilcoxon). CONCLUSIONS: Laparoscopic fistula excision combined with omentoplasty is a good treatment modality with a high healing rate for high rectovaginal fistulas and an acceptable complication rate

Perianal Crohn’s disease: A review

Perianal involvement in Crohn's disease (CD), which encompasses fistulas, ulcers, abscesses, strictures and cancer, can lead to significant impairment in quality of life. The objective of this article is to review the major perianal complications of CD and the current medical and surgical modalities used to treat them. Antibiotics are commonly used despite a lack of controlled trials to validate their use and should be used as a bridge to maintenance therapy. The anti-metabolites azathioprine and 6-MP have shown a positive response in terms of fistula closure, although these data are mostly from trials looking at this as a secondary endpoint. Infliximab is an effective agent for induction and maintenance of treatment of fistulizing CD. Further studies to evaluate the use of subcutaneous anti-tumor necrosis factors are needed to convincingly prove their efficacy for perianal fistulizing disease. In CD, clinicians should avoid surgery as a first-line approach for skin tags, hemorrhoids or fissures in the setting of proctitis. Surgery, particularly lateral internal sphincterotomy, in combination with medical therapy is associated with higher fissure healing rates in the absence of proctitis. Fistulotomy is curative for most simple low perianal fistulae, but complex fistulas often require sphincter-sparing surgical procedures. Less invasive approaches such as a chemical sphincterotomy should be used first, with therapy escalated only if this fails
