腹部超音波検査は非侵襲的で比較的簡易なため,任意型検診に広く用いられている.反面,検査環境における規定や統一した診断基準が明確ではなかった.施設間の標準化を行うためには,共通の診断基準を使用し,超音波診断に客観性を持たせることが必要である.2014年には日本超音波医学会,日本消化器がん検診学会,日本人間ドック学会の3学会共通の腹部超音波検診判定マニュアルが作成された.同年,全国労働衛生団体連合会では腹部超音波精度管理調査を開始した.判定マニュアルを普及し検査環境の整備,判定基準の統一化を行うことや,外部精度管理を実施し客観的な評価を受けることは腹部超音波検診の精度向上に必要である.今回,腹部超音波検診の現状から標準化へ向けての課題を整理し報告する.

Abdominal ultrasound examinations are noninvasive and relatively easy to perform. Therefore, they are widely used for voluntary clinical screenings. However, there are no clear regulations or standardized examination criteria for such examinations. To achieve inter-facility standardization, all procedures must be evaluated objectively, following the same guidelines and diagnostic criteria. In 2014, the Manual for Abdominal Ultrasound in Cancer Screening and Health Checkups was created. This is a standardized manual used by the Japan Society of Ultrasonics in Medicine, the Japanese Society of Gastrointestinal Cancer Screening, and the Japan Society of Ningen Dock. In the same year, the National Federation of Industrial Health Organization began a survey on abdominal ultrasound accuracy control. Wide use of the manual will improve testing conditions and help in standardizing criteria, which should enhance the accuracy of abdominal ultrasound screenings. Implementing third-party accuracy control and undergoing objective evaluations will also contribute to enhancing the accuracy of the screenings. This report summarizes the current status of abdominal ultrasound screening and discusses the challenges faced in its standardization.
