If the cecum is still healthy, it may occasionally be returned to a normal position and sutured in place.Cases of volvulus were described in ancient Egypt as early as 1550 BC. It occurs most frequently in Africa, the Middle East, and India. Rates of volvulus in the United States are about 2–3 per 100,000 people per year. Sigmoid and cecal volvulus typically occurs between the ages of 30 and 70. Outcomes are related to whether or not the bowel tissue has died. The term volvulus is from the Latin "volvere"; which means "to roll". Signs and symptoms
Regardless of cause, volvulus causes symptoms by two mechanisms:
Bowel obstruction manifested as abdominal distension and bilious vomiting. Ischemia (loss of blood flow) to the affected portion of intestine.Depending on the location of the volvulus, symptoms may vary. For example, in patients with cecal volvulus, the predominant symptoms may be those of small bowel obstruction (nausea, vomiting and lack of stool or flatus), because the obstructing point is close to the ileocecal valve and small intestine. In patients with sigmoid volvulus, although abdominal pain may be present, symptoms of constipation may be more prominent. Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. Ultimately, this can result in necrosis of the affected intestinal wall, acidosis, and death. This is known as a closed-loop obstruction because there exists an isolated ("closed") loop of bowel.
Perifollicular fibroma is a cutaneous condition, a benign tumor usually skin colored, most often affecting the face and upper trunk. : 674
