A specimen collection technique to ensure that the resected specimen is safely retrieved after duodenal ESD
In recent years, endoscopic submucosal dissection (ESD) has been applied for duodenal tumors.1-3 The advantage of en bloc excision in ESD is that it allows precise pathological examination.4 For this reason, it is important to ensure that the resected specimen is collected. However, there is no report on the collection method for duodenal specimens resected by ESD.Usefulness of a handmade distal endoscope attachment with a transparent tape
Distal attachments placed on the endoscope tip can improve visualization of the endoscopic field and have been applied for a variety of endoscopic procedures (eg, colonic insertion, detection, diagnosis, and treatment).1 Although manufactured distal attachments are commercially available, it may be necessary to prepare different types to suit different endoscopes because the distal outer diameters of endoscopes vary widely. In addition, cost-effectiveness leads to hesitation about the use of commercially available distal attachments in daily practice.
