Abstract
The ecological impact of endoscopy is significant [1] and it is therefore crucial to seek strategies [2] [3] for reducing the number of devices used and therefore the weight of waste generated [4]. Endoscopy procedures frequently involve both upper and lower gastrointestinal procedures, for example, gastric sampling for Helicobacter pylori and metaplasia detection on the one hand and colonoscopy with a high risk of detecting polyps on the other. Gastric sampling commonly involves the use of biopsy forceps. Nowadays, cold snaring is the reference method for removing small polyps (< 10 mm), which are very frequently detected during a screening colonoscopy. It means that two devices are usually used during a combined upper and lower gastrointestinal endoscopy procedure, even though cold snaring can perform gastric sampling adequately, and, in fact, provides larger samples with more tissue for pathologists to analyze.
