“…A more proximal lesion will not obstruct as easily due to the wider diameter of bowel and less solid stool. 3 Nausea and vomiting, which are prevalent in small bowel obstructions, may not present if the patient has a competent ileocecal valve. 4 A competent ileocecal valve places the patient at risk for a closed loop obstruction as contents of the colon are unable to move forward or backward.…”

“…Bowel diameter over 10 cm is associated with an increase in the risk of perforation. 3 Colonoscopy can have both diagnostic and therapeutic benefits. 3 Colonoscopy can demonstrate mucosal or submucosal lesions that can contribute to an LBO.…”

“…The most common cause of LBOs in the United States is adenocarcinoma of the colon and rectum. [1][2][3] This represents over 50 to 60% of LBOs. 3,4 Diverticular disease represents approximately 10 to 20% of cases.…”

“…[1][2][3] This represents over 50 to 60% of LBOs. 3,4 Diverticular disease represents approximately 10 to 20% of cases. 3,4 Large bowel volvulus represents approximately 10 to 15% of LBOs.…”

“…3,4 Diverticular disease represents approximately 10 to 20% of cases. 3,4 Large bowel volvulus represents approximately 10 to 15% of LBOs. 3,4 The remaining LBOs are caused by rarer conditions such as inflammatory bowel disease, hernia, adhesion, endometriosis, intussusception, and functional disorders of the colon.…”
