most common cause of large bowel obstruction
The prevalence of mechanical large-bowel obstruction (LBO) increases with age as does its main causes, colon cancer and diverticulitis. Sigmoid volvulus and cecal volvulus are also potential causes of this disorder. [2] See the following images.
Major complaints in patients with large-bowel obstruction (LBO) include abdominal distention, nausea, vomiting, and crampy abdominal pain. An abrupt onset of symptoms makes an acute obstructive event (eg, cecal or sigmoid volvulus) a more likely diagnosis.
