Large bowel obstruction with an empty rectum and twisted mucosal folds narrowing the lumen at about 20 cm with normal mucosa is sigmoid volvulus. Volvulus is a twist of the colon around its mesentery, and the sigmoid is the most common site.
- Carcinoma would show an abnormal mucosal mass.
- Ischemic colitis would show abnormal mucosa.
- Diverticulitis presents with fever and LLQ tenderness, not a twisted lumen.
