Many forms of endoclips exist of different shapes and sizes, including two and three prong devices, which can be ...

[2] It may be indicated by the passage of fresh red blood rectally, especially in the absence of bloody ...
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.
