Run to the operation room!

Clinical Scenario

A 70 yo woman is brought to the ED by ambulance.
She’s suffering from vomit, lach of flatus and abdominal pain since 24 hours says the nurse. 
She’s pale, the abdomen shows a midline scar. There is diffused tenderness with rebound.
Abdomen US and X rays show abnormal distended loop of small bowel.
