Anterior enterocele following cystectomy for intractable interstitial cystitis.
PURPOSE: We clinically define the development of an anterior vaginal wall hernia following cystectomy for the management of intractable interstitial cystitis and establish surgical technique for its correction. MATERIALS AND METHODS: Of 27 women who underwent simple cystectomy and urethrectomy for intractable interstitial cystitis an anterior vaginal wall hernia developed in 3 (71, 56 and 61 years old) at 8, 14 and 16 months, respectively, postoperatively. Clinical appearance was similar to a midline cystocele but it contained bowel contents in the form of an anterior enterocele. Anterior enterocele was associated with vaginal vault prolapse in 1 patient who was treated with transvaginal sacro-spinous colpopexy. Patients with isolated anterior enterocele required a transabdominal approach with mobilization of the intestinal hernia contents and obliteration of the intervaginal abdominal wall space. RESULTS: At 12, 19 and 33 months following reconstruction prolapse has not recurred, and sexual function was restored in 1 patient. CONCLUSIONS: These cases suggest that an extended simple cystectomy performed on women with intractable interstitial cystitis may result in a weakening of the anterior vaginal wall with resultant anterior enterocele formation. When it is associated with vaginal vault prolapse a transvaginal technique may be considered but we prefer a transabdominal approach for an isolated anterior enterocele. Prevention of this entity may be warranted at the time of cystectomy.
