Causes:

Approximately 60% of mechanical LBOs are caused by malignancies, 20% are caused by diverticular disease, and 5% are the result of colonic volvulus.
Obstructions that result from tumors have a gradual onset and result from tumor ingrowth into the colonic lumen.
Diverticulitis is associated with muscular hypertrophy of the colonic wall. Repetitive episodes of inflammation cause the colonic wall to become fibrotic and thickened, leading to luminal narrowing.
Colonic volvulus results when the colon twists on its mesentery. This impairs the venous drainage and arterial inflow. Symptoms are usually abrupt.

Sigmoid volvulus typically occurs in older individuals with a history of constipation and straining.

Cecal volvulus is caused by a congenital defect in the peritoneum, which results in inadequate fixation of the cecum. This type of volvulus generally occurs in a younger population.
Intussusception is primarily a pediatric disease. It is estimated that between 5-16% of all intussusceptions in the western world occur in adults. Approximately two thirds of adult intussusception is caused by tumors. Two main types of intussusception affect the large bowel.

Enterocolic intussusceptions involve both small and large bowel. These are composed of either ileocolic intussusceptions or ileocecal intussusceptions, depending on where the lead point is located.

Colocolic intussusceptions involve only the colon. They are classified as either colocolic or sigmoidorectal intussusceptions
