There are actually a few different types of twisted intestines, or "volvulus," and recommendations would be based on which type you have. Sigmoid volvulus, which is the most common type and usually found in people over age 50, can be treated with rectal tube decompression (sucking excess air out and allowing the bowel to untwist on its own) which you may have had in the hospital. If the volvulus recurs or tube decompression fails, surgery may be needed. Some doctors recommend surgery even if tube decompression is successful in order to avoid recurrence because it is so common.

You should discuss this persistent pain with your doctor, and seek help immediately if your pain is severe, or if you have another episode of blood-stained stools. Volvulus is typically a serious and acute (short-duration) problem, so while your pain over the past year could conceivably be related to twisting and untwisting of the bowel, it may also be from another cause that led to the discovery that you have the potential for twisted bowel. It's difficult to speculate without knowing your full history and test results, so your best option is to touch base with your doctor and inform him or her of your continued pain.
