AWC®duo in ESD: 100% en-bloc resection, no adverse events

First experience with AWC®duo in ESD demonstrates its potential as an easy-to-use and versatile tool for mechanical traction, achieving a 100% en-bloc resection rate without any device-related adverse events

Key findings

• 100% en-bloc resection rate (6/6)
• No device-related adverse events
• AWC®duo utilized in all 6 procedures, with a median utilization rate of 60%
• Subjective reduction in procedure time observed in 4 out of 6 cases
• Grasping forceps introduced via the AWC®duo enabled effective tissue retraction; knife insertion through the AWC®duo allowed alteration of the dissection angle and facilitated suction via the endoscope
• Integrated cap of AWC®duo used in all cases during the dissection phase, with no perceived limitation compared to conventional caps

Study details

• Retrospective case series (April–August 2025) at the RKH Klinikum Ludwigsburg, Germany
• 6 patients undergoing ESD with the AWC®duo using a standard gastroscope (Olympus GIF-EZ1500)
• Aim: Description of first experiences with AWC®duo in ESD, assessing lesion characteristics, en-bloc and R0 resection rates, procedural parameters, complications, and AWC®duo utilization with additional instruments
• Lesion site: Rectum (4/6) and stomach (2/6)
• Median lesion size: 58 mm
• Median resection time: 130 min
