Which of the following methods is NOT used to control bleeding after endoscopic resection?

Controlling bleeding after endoscopic resection is critical for patient safety and successful outcomes. Among the methods listed, alcohol injection is not commonly used for this purpose. While alcohol can induce coagulation and has been utilized in some other medical contexts, it is not a standard practice for managing bleeding during or after endoscopic resections.

Epinephrine injection is a widely used technique due to its ability to vasoconstrict and temporarily reduce blood flow to the area, thus helping to control bleeding effectively. Endoclip application also serves as a reliable method for mechanically sealing bleeding sites by providing immediate pressure and closure of the vessels. The detachable loop application is another valid method that allows for the entrapment of bleeding vessels by creating a loop that may occlude the vessel.

Using alcohol injection is not a recognized or effective method for controlling bleeding in endoscopic surgery, which is why it stands out as the answer to this question. Focusing on approved techniques such as epinephrine injection, endoclips, and detachable loops ensures that clinicians manage bleeding effectively and adhere to best practices in endoscopic surgery.
