Objectives: The International Ovarian Tumor Analysis (IOTA) provides a specific terminology for adult ovarian masses, while, currently, there is no systematic classification for preoperative assessment of adnexal lesions in childhood and adolescence. This study aims to survey Italian pediatric surgeons to evaluate ovarian masses' management (from diagnosis to treatment) in patients aged 1-18.

Methods: A 27-question survey was distributed. It consisted of questions regarding the management and use of ultrasound and IOTA terminology in diagnosing ovarian masses in childhood and adolescence, in emergency regimes and in planned surgeries.

PURPOSE AND OBJECTIVES OF THE CLINICAL TRIAL The aim of the present study is to propose a survey among Italian Pediatric Surgeons (inside the Società Italiana di Chirurgia Pediatrica-SICP) to evaluate the current management of ovarian masses in patients aged 1 -18, in terms of preoperative work up and surgical modalities.

EXPERIMENTAL DESIGN

PRIMARY OBJECTIVE:

To evaluate the current management of ovarian masses in patients aged between 1 and 18.

EXPERIMENTAL PLAN:

SETTING:

This is an online survey designed using REDCap forms feature. Data will be collected in a period of 6 months. The informed consent forms for participation, use of personal data and the link for the questionnaire will be sent by e-mail to all Italian Pediatric Surgeons belonging to the SICP. The surgeons who accept to participate, will return both signed consent forms and a copy of their Identity Card.

The survey is divided into seven sections.

• Section 1: demographic data.

• Section 3: management of pediatric patients in emergency.
• Section 4: management of pediatric patients who had planned surgery.
• Section 5: additional management data.
• Section 6: knowledge of the IOTA group and terminology.
• Section 7: availability to participate in a multi-center retrospective study.

Questions asked for responses using yes/no, multiple-choice, or short freeform written answers. More than one response could be given for many questions, it is specified.
