"inflammation secondary to peritoneal endometriosis, fistulas (e.g. fistulising diverticulitis), abscess, or aneurysm may pull in and tether small bowel, causing kinking and obstruction by a similar mechanism to adhesive disease."
"The degree of obstruction can be described as complete or incomplete (alternatively high-grade or partial) depending on whether enteric contents can pass beyond the site of obstruction. This is often inferred based on the degree of upstream small bowel dilation, the severity of narrowing at the transition point, and the passage of oral contrast (if administered)."

"Closed-loop small bowel obstruction occurs when the bowel is obstructed at two points, typically close to one another, entrapping enteric contents in a closed-loop segment and leading to progressive vascular compromise with a high risk of developing ischaemia and infarction. The importance of this distinction is discussed in detail below. Non-closed-loop obstruction is also known as open-loop or simple obstruction 11."

"The clinical presentation of small bowel obstruction varies according to its aetiology. Gradual partial obstruction typically manifests with intermittent abdominal discomfort, decreased bowel movements, and vomiting. In contrast, closed-loop obstruction presents more acutely, often with sudden onset of abdominal pain and signs of shock due to rapid vascular compromise. Vomiting may be absent in such cases, as the proximal bowel may not have had sufficient time to dilate before vascular compromise leads to symptoms of severe pain."
