Figure 14  Stapfer type III perforation. A and B: Axial (A) and coronal (B) contrast-enhanced computed tomography images showed a choledochal microperforation in a 28-year-old patient following sphincterotomy and plastic stent placement. Following the procedure, the patient developed severe periumbilical abdominal pain accompanied by guarding and rebound tenderness. The free air was confined to the periportal region and extended from the hepatoduodenal ligament to the hepatic hilum (blue arrows).
