Risk of delayed bleeding after colorectal endoscopic submucosal dissection: the Limoges Bleeding Score.

Background: Clinically significant delayed bleeding (CSDB) is a frequent, and sometimes severe, adverse event after colorectal endoscopic submucosal dissection (ESD). We evaluated risk factors of CSDB after colorectal ESD.

Methods: We analyzed a prospective registry of 940 colorectal ESDs performed from 2013 to 2022.

What is the cost of endoscopic submucosal dissection (ESD)? A medico-economic study.

Introduction: Endoscopic submucosal dissection (ESD) is the gold-standard treatment for superficial lesions of the digestive tract. No medico-economic study has been conducted in Europe.

Material And Methods: A monocentric study was conducted including all patients undergoing ESD between January 2015 and December 2017.

A local structured training program with live pigs allows performing ESD along the gastrointestinal tract with results close to those of Japanese experts.

Background And Aims: The high specific skill needed by ESD limit its widespread use in Europe and animal training is recommended in Europe to improve the results of ESD that are far from Japanese at present. We create a local training program using live pigs as models, along with our human cases, to provide continuous exposure to the technique.

Methods: Between February 2013 and December 2015, two young operators performed 55 pig gastric ESDs in parallel with 62 human cases for large superficial cancerous lesions.

High-pressure injection of glycerol with HybridKnife for ESD is feasible and increases the ease and speed of the procedure: an in vivo study in pigs and first use in human.

Background And Aims: The HybridKnife water-jet system (ERBE, Tubingen, Germany) has been shown to increase dissection speed and decreased the risk of perforation during endoscopic submucosal dissection (ESD). Glycerol mixture is a viscous, long-lasting solution preferentially used by Japanese ESD experts. The combination of the HybridKnife system with a glycerol solution has not been evaluated to date.

Obscure bleeding colonic duplication responds to proton pump inhibitor therapy.

We report the case of a 17-year-old male admitted to our academic hospital with massive rectal bleeding. Since childhood he had reported recurrent gastrointestinal bleeding and had two exploratory laparotomies 5 and 2 years previously. An emergency abdominal computed tomography scan, gastroscopy and colonoscopy, performed after hemodynamic stabilization, were considered normal.
