CT Features of Mallory-Weiss Syndrome.

We report in this clinical case Mallory-Weiss syndrome suspected on computed tomography (CT) and confirmed on endoscopy. Mallory-Weiss syndrome is a rare cause of upper gastrointestinal bleeding from vomiting-induced mucosal laceration(s) at the gastroesophageal junction. The description of Mallory-Weiss Syndrome is rare on imaging and this observation provides CT semiological elements useful in detecting signs of Mallory-Weiss syndrome.

Diagnostic endoscopic submucosal dissection for colorectal lesions with suspected deep invasion.

Background: Endoscopic submucosal dissection (ESD) is potentially a curative treatment for T1 colorectal cancer under certain conditions. The aim of this study was to evaluate the feasibility and effectiveness of ESD for lesions with a suspicion of focal deep invasion.

Methods: In this retrospective multicenter study, consecutive patients with colorectal neoplasia displaying a focal (< 15 mm) deep invasive pattern (FDIP) that were treated by ESD were included.
