This is what I found out by googling.Sigmoid means S shaped. Tortuous means it's more curvy than usual, but rarely has particular significance. A tortuous sigmoid simply means that there are a lot of twists and turns. By itself, this is an anatomical variant and not linked to a specific diseaseHope this helps a bit.
Inflammatory bowel disease such as ulcerative colitis and Crohn's disease may occur here. Diverticulitis, in which little outpouchings of bowel form and become inflamed, is more common in the sigmoid than any other part of the bowel. Small growths called polyps, as well as cancers, also favour this site. The good thing about investigating sigmoid disease is that this part of the colon isn't far from the outside world. It is easy to pass a rigid sigmoidoscope into the anus and get a decent view.
