Abstract
Background
Retrieval of polyps resected from the colorectum is time consuming, despite the availability of various devices, such as grasping forceps, nets, and suction traps, for this purpose. A novel device for retrieval of polyps was developed and tested.
Methods
Patients with polyp(s) less than or equal to 6 mm in diameter were included in this study. The effectiveness of the device for polyp retrieval was evaluated.
Observations
In total, 180 of 184 polyps were retrieved from 100 patients. Four polyp specimens (2.2%) were lost after polypectomy. None of the retrieved specimens were damaged. All retrieved polyps could be assessed histopathologically, and a definitive diagnosis was made.
Conclusions
The newly developed device proved to be reliable when used in clinical practice.
