Volvulus occurs when the intestine twists around itself and the mesentery that supports it, creating an obstruction. The area of intestine above the obstruction continues to function and fills with food, fluid, and gas. The mesentery may become so tightly twisted that blood flow to the affected part of the intestine is cut off. This situation can lead to death of the blood-starved tissue and tearing of the intestinal wall—a life-threatening event and a medical emergency. Sigmoid volvulus—twisting of the sigmoid colon—accounts for the majority of cases, with cecal volvulus—twisting of the cecum and ascending colon—occurring less frequently. Other symptoms may develop more slowly but worsen with time, such as constipation, inability to pass gas, and abdominal swelling.

Your rectum is the last part of your colon. Rectal prolapse is when part of the rectum bulges out of the anus. At first, a prolapse may happen only after a bowel movement. The prolapsed part of the rectum may then slip back through the anal canal on its own.

While most anorectal conditions are not life-threatening, they may cause significant discomfort. Patients may make an incorrect self-diagnosis of hemorrhoids.
