Pilot Study Evaluating Outpatient Management of Tubo-ovarian Abscesses

Pelvic inflammatory diseases (PID) require antibiotic treatment. Among PID, the investigators distinguish: pelvi-peritonitis and pelvic collections such as Douglas abscess and/or tubo-ovarian abscess (TOA).

Recent recommendations published in December 2018 by the National College of French Gynecologists and Obstetricians (CNGOF) suggest that it is preferable to drain TOA when their size is greater than 3-4 cm. Ultrasound-guided transvaginal drainage is recommended as first-line treatment because of its ease of performance and its effectiveness. In the literature, many authors have demonstrated the feasibility and efficacy of transvaginal drainage associated with antibiotics in the treatment of TOA. Since ultrasound-guided transvaginal drainage is a less invasive alternative therapeutic procedure than laparoscopy for the drainage of TOA, it would be compatible with outpatient management. This mode of management can be carried out in a dedicated outpatient or functional exploration room with the help of a nurse but without an anesthetic team present. This gesture is simple and short-lived. In addition, the antibiotics used have pharmacological properties allowing oral intake from their initiation.

The investigators have proposed a new service protocol to treat TOA in this outpatient mode. The investigators therefore wish to analyze this new protocol from these three angles: 1/ the feasibility of this care, 2/ the quality of life of the patients through questionnaires given throughout the care and 3/ an evaluation of the 'efficiency.
