The left colon becomes displaced and lodged in the nephrosplenic space. Entrapment over the nephrosplenic ligament results in simple obstrcuction of the colon, usually without vacular compromise. The exact cause is unknown but it is thought that changes in the ingesta, gas content and motor activity of the colon are important factors.

Diagnosis is usually made on a combination of rectal examination and abdominal ultrasound. On rectal examination the pelvic flexure or left colon can be felt in the nephrosplenic space, the spleen is often displaced towards the midline. The displaced colon becomes distended with gas due to compression over the nephrosplenic ligament.
