Group A streptococcal peritonitis and ruptured tubo-ovarian abscess three years after Essure® insertion: a case report.

We describe a complicated ruptured Streptococcus pyogenes tubo-ovarian abscess (TOA) and peritonitis in a 24-year-old woman, necessitating eventual hysterectomy and a prolonged intensive care unit (ICU) admission 3 years after successful tubal occlusion with Essure® (Conceptus, Inc., Mountain View, CA) microinsert devices. The patient is a 24-year-old gravida 3, para 2, aborta 1 (G3P2Ab1) who had a 1-day history of worsening right lower quadrant pain without associated fever or cervical motion tenderness. Patient's medical history was complicated by mitochondrial neurogastrointestinal encephalopathy (MNGIE). Upon her admission to the hospital, an exploratory laparoscopy was performed. Intraoperative findings revealed a ruptured right-sided TOA. S. pyogenes was isolated from the peritoneal fluid and cervicovaginal cultures. After the laparoscopy, the patient experienced initial improvement but abruptly worsened and on postoperative day 7 was returned to the operating room for a planned repeat exploration and total abdominal hysterectomy. Gross pathological examination of the uterus showed appropriate Essure insert placement. Based on this case, tubal occlusion by induced fibrosis may not be a sufficient obstacle in preventing ascending pelvic infections.
