Double-balloon enteroscopy offers a number of advantages to other small bowel image techniques, including barium imaging, wireless capsule endoscopy and push enteroscopy: It allows for visualization of the entire small bowel to the terminal ileum.

In medicine, the ileal pouch–anal anastomosis (IPAA), also known as restorative proctocolectomy (RPC), ileal-anal reservoir (IAR), an ileo-anal pouch, ileal-anal pullthrough, or sometimes referred to as a J-pouch, S-pouch, W-pouch, or a pelvic pouch, is an anastomosis of a reservoir pouch made from ileum (small intestine) to the anus, bypassing the former site of the colon in cases where the ...
Pouchoscopy is a minimally invasive endoscopic procedure to examine an ileo-anal pouch, a replacement for the colon / rectum which is surgically created from the small intestine (ileum) as treatment for ulcerative colitis, a preventive measure in certain genetic illnesses such as FAP or HNPCC or as a procedure in the treatment of colon cancer.
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
3–7% of people having duodenal biopsy Duodenal lymphocytosis , sometimes called lymphocytic duodenitis , lymphocytic duodenosis , or duodenal intraepithelial lymphocytosis , is a condition where an increased number of intra-epithelial lymphocytes is seen in biopsies of the duodenal mucosa when these are examined microscopically.
One example is a situation where the cancer tumor is causing a blockage (obstruction). [3] In such a case, the ileostomy may be temporary, as the common surgical procedure for colorectal cancer is to reconnect the remaining sections of colon or rectum following removal of the tumor provided that enough of the rectum remains intact to preserve ...
A biopsy is a small piece of tissue removed primarily for the purposes of surgical pathology analysis, most often in order to render a definitive diagnosis. Types of biopsies include core biopsies , which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or ...
Proctoscopy, or rectoscopy, is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope, although the latter may be a bit longer) is used to examine the anal cavity, rectum, or sigmoid colon.
