What type of larger polyps may require a net for retrieval?

Larger polyps often require a net for retrieval due to their size, which increases the likelihood that they cannot be easily grasped with standard endoscopic tools such as forceps. The use of a retrieval net allows for safer and more effective removal of these larger lesions, minimizing the risk of fragmentation or leaving behind parts of the polyp that could lead to complications or recurrence.

In the context of polyp retrieval, the size and structure of the polyp are critical factors. Larger polyps may be more difficult to manage due to their volume and morphology, making a net, which is designed to encompass and secure the polyp, a useful tool during endoscopic procedures. By using a net, the clinician can ensure that the entire polyp is captured and extracted in one piece, facilitating a more straightforward and complete resection.

Smaller polyps, sessile ones, or those that are inflamed might be more amenable to standard retrieval techniques and may not necessitate the specialized approach that larger polyps do. Cystic or fluid-filled polyps could also pose different challenges that may not directly correlate with size alone, hence they may not consistently require a net for retrieval. The emphasis on larger polyps highlights the need for appropriate tools and techniques
