Vaginal evisceration after a pelvic operation is a rare gynecological emergency. When intercourse is the cause, most cases occur within 1 year of surgery. A 53-year-old woman presented to the emergency room for vaginal evisceration half a day after the first postoperative occurrence of intercourse 3 years after an abdominal hysterectomy and bilateral salpingo-oophorectomy. In an emergency laparotomy, the protruding small bowel was replaced within the abdominal cavity. The avulsed vaginal cuff, which measured 6 cm in length and had atrophic but non-necrotic margins, was sutured. Women who go for long periods without intercourse after a hysterectomy, especially post-menopausal women, should be made aware of unrecognized vaginal atrophy that could, in some cases, lead to rupture and evisceration during the next occurrence of intercourse.
