When does bleeding typically occur after an endoscopic resection?

Bleeding after an endoscopic resection can occur at various times, and the correct response highlights the variability in timing. It's important to recognize that immediate bleeding might occur during the procedure, but post-procedural bleeding can also arise in the days following the intervention. Specifically, bleeding can happen within the first couple of weeks as the surgical site heals and vascular structures adjacent to the resection site may become more prone to bleeding due to factors like inflammation, disruption of the vasculature, or formation of slough.

Bleeding that occurs within the first two weeks can be due to a variety of reasons, including technical issues from the original procedure, a clot falling off, or mucosal healing impacting the vascular supply. By encompassing both immediate and up to two weeks as a window for potential bleeding, this choice accurately reflects clinical reality and practice. Thus, understanding that the risk remains present until at least two weeks post-procedure is critical for monitoring and managing patient recovery effectively.
