Endoscopic submucosal dissection versus endoscopic mucosal resection for laterally spreading rectal tumours.

Aim: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are the two main techniques used for endoscopic resection of superficial rectal tumours. The aim of this study was to compare the outcomes of ESD and EMR in treating superficial rectal tumours.

Method: A retrospective observational study was conducted at two French centres including all patients treated with ESD or EMR for superficial rectal tumours.

Does the shape of the copper intrauterine device play a role in expulsion? Results from the ongoing European Active Surveillance Study on LCS12.

Objective: To compare the incidence of expulsion for different copper intrauterine device (IUD) shapes.

Study Design: We conducted a secondary analysis of the ongoing, prospective, non-interventional European Active Surveillance Study on LCS12 (EURAS-LCS12). Users of newly inserted IUDs were recruited in 10 European countries via a network of approximately 1200 clinicians.
