Study summary

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.

What researchers measure

Primary outcomes

  1. Cure rate

    The cure rate is defined by a composite criterion at 1 month of the procedure: * Apyrexia (temperature \<38,0°c) * Absence of re-intervention for pelvic collection (TOA) in the month following the transvaginal drainage * Absence of second-line antibiotic therapy, extension, new antibiotic in the month following the transvaginal drainage

    Time frame: one month

Secondary outcomes

  1. eligibility

    Number of patients included in the protocol compared to the number of eligible patients

    Time frame: 2 years

  2. Discharge

    Discharge from hospital within 24 hours of the drainage

    Time frame: 2 years

  3. Rehospitalization

    Rehospitalization: reason, duration and care

    Time frame: 1 month

  4. Measure of Pain

    Pain is assessed by Numerical Rating Scale (NRS) (0-10). Absence of pain (EN=0/10), mild pain (EN\<4/10), absence of metrorrhagia and absence of leucorrhoea

    Time frame: 1 month

  5. residual mass

    Absence of residual mass ≥ 3cm on pelvic ultrasound

    Time frame: 1 month

  6. complications

    Presence of complications (digestive, urinary, parietal)

    Time frame: 1 month

  7. antibiotic therapy

    Change of antibiotic therapy (except adequate adaptation to the antibiogram). Change of antibiotic therapy is assessed by the need to add another antibiotic with a broader spectrum of action, following a poor clinical or biological evolution.

    Time frame: 1 month

  8. Quality of life with EQ-5D-5L

    Satisfaction and Quality of life completed by the patients on the day of the drainage before the procedure, at 48 hours and at 1 month

    Time frame: 1 month

  9. Quality of life with Medical Outcome Study Short Form 12 (SF12)

    Satisfaction and Quality of life, questionnaires completed by the patients on the day of the drainage before the procedure, at 48 hours and at 1 month. Each question is assessed on a Likert scale, with 5 to 6 possible levels of response possible responses. The 8 dimensions combine synthetic information to calculate a physical composite score (PCS) and a mental score (SCP) and a mental composite score (SCM). The higher the score, the greater the patient's ability.

    Time frame: 1 month

  10. Quality of life with Patient Global Impression of Improvement (PGI-I) questionnaires

    Satisfaction and Quality of life , questionnaires completed by the patients on the day of the drainage before the procedure, at 48 hours and at 1 month The PGI-I is a transition scale that is a single question asking the patient to rate their urinary tract condition now, as compared with how it was prior to before beginning treatment on a scale from 1. Very much better to 7. Very much worse.

    Time frame: 1 month

  11. Evaluation of the direct costs

    Evaluation of the direct costs of care for the 3 treatment strategies for complicated IGH of the ATO type, according to a time horizon of 1 month and a collective perspective

    Time frame: 1 month
