With large bowel obstruction what are my treatment options?

Bowel obstruction. Bowel obstruction can be partial or complete, due to problems outside the gut or problems within the gut, functional or space-occupying, acute or resolving, small bowel or large bowel. When obstruction is complete, surgery is needed. If due to infection, ibd, or disease external to the GI tract, treatment may be medical &/or even just observational with supportive care until the gut "wakes up.".
Surgery. Surgical treatment varies depending on severity of the obstruction, but treatment is urgent.
