What does partial malrotation of the small bowel mean?

Think garden hose. Your intestines are a complex hose like structure that forms outside of the body during fetal life & drops back in, settling in place. For some, odd placing& increased mobility allow it to twist on itself like a garden hose at some point. Repair requires surgeon untwist the bowel & examine it .Sometimes the twist cuts off the blood & a segment dies, requiring removal. The bowel is then secured.
