Postoperative Pelvic Abscess after Cervicovaginal Canalization for Congenital Cervical and Vaginal Agenesis: A Report of 4 Cases.

OBJECTIVE

To investigate the clinical characteristics and outcomes of pelvic abscess after cervicovaginal canalization for congenital cervical and vaginal agenesis.

CASES: Four patients who had pelvic abscess after cervicovaginal canalization for congenital cervical and vaginal agenesis are reported. The mean onset time of pelvic abscess after primary canalization was 67.7 months. Three patients presented with pelvic endometriosis. Three patients underwent cervical catheter or intrauterine device placement, with a mean time of 62 months. All patients underwent hysterectomy and pelvic abscess removal, and no recurrence of pelvic abscess or formation of pelvic pseudocysts was observed during the follow-up.

CONCLUSION

Pelvic abscess after cervicovaginal canalization was mainly due to re-obstruction of the neocanal, the risk of which may increase when surgery is combined with prolonged cervical stent placement and pelvic endometriosis. Hysterectomy should be suggested once pelvic abscess is diagnosed.
