Abstract

There are a variety of causes of intestinal obstruction, with the most common cause being malignant diseases; however, volvulus, inflammatory bowel disease or diverticulitis, radiation injury, ischemia, and pseudo-obstruction can also cause colonic obstruction. These are benign conditions; however, delayed diagnosis of acute intestinal obstruction owing to these causes can cause critical complications, such as perforation. Therefore, high levels of clinical suspicion and appropriate treatment are crucial. There are variable treatment options for colonic obstruction, and endoscopic treatment is known to be a less invasive and an effective option for such. In this article, the authors review the causes of benign colonic obstruction and pseudo-obstruction and the role of endoscopy in treating them.

  Fig. 5. Schema showing the radial incision and cutting method [81]. (A) Four or more incisions are created into the stenosed site using the IT Knife Nano (Olympus Medical Systems, Tokyo, Japan). (B) The flaps formed by the incisions are removed using a blade. (C) The scar tissue is excised in an arc from the incision along the lumen. The staples serve as good landmarks for determining the depth of the cutting line.
