Development and external evaluation of a self-learning auto-segmentation model for Colorectal Cancer Liver Metastases Assessment (COALA).

Objectives: Total tumor volume (TTV) is associated with overall and recurrence-free survival in patients with colorectal cancer liver metastases (CRLM). However, the labor-intensive nature of such manual assessments has hampered the clinical adoption of TTV as an imaging biomarker. This study aimed to develop and externally evaluate a CRLM auto-segmentation model on CT scans, to facilitate the clinical adoption of TTV.

Intra- and interobserver reliability in measuring aortic root rotation with cardiac magnetic resonance imaging.

Background: The rotational position of the aortic root (AoR) is of substantial clinical interest as it has been associated with severe aortic complications, such as aortic dissections. We described a cardiac magnetic resonance (CMR)-based method for measuring AoR rotation and evaluated the reliability of measurements.

Methods: CMR was used for measuring AoR rotation in 50 consecutive healthy subjects.

Reproductive and obstetrical outcomes after treatment of retained products of conception: hysteroscopic removal vs ultrasound-guided electric vacuum aspiration, a prospective follow-up study.

Background: Traditionally, curettage has been the most widely performed surgical intervention for removing retained products of conception. However, hysteroscopic removal is increasingly performed as an alternative because of the potentially lower risk of intrauterine adhesions and higher rates of complete removal. Until recently, studies comparing curettage with hysteroscopic removal regarding reproductive and obstetrical outcomes were limited, and data conflicting.

Operative hysteroscopy versus ultrasound-guided electric vacuum aspiration for removal of retained products of conception: A prospective cohort study.

Objectives: To compare intrauterine adhesion (IUA) formation after hysteroscopic removal (HR) of retained products of conception (RPOC) with IUA formation after ultrasound-guided electric vacuum aspiration (EVA) and externally validate the outcomes of an RCT.

Study Design: This prospective cohort study was conducted from April 2015 until June 2022 in 2 Dutch teaching hospitals and one Belgian university hospital. Women opting for EVA underwent the procedure as soon as possible.

Hysteroscopic morcellation vs. curettage for removal of retained products of conception: a multicenter randomized controlled trial.

Objective: To study the comparison between hysteroscopic morcellation (HM) of retained products of conception (RPOC) with ultrasound (US)-guided electric vacuum aspiration in terms of intrauterine adhesion (IUA) formation, efficacy, and complications.

Design: A randomized controlled, nonblinded trial.

Setting: Three teaching hospitals and one university hospital from April 2015 to June 2022.
