[Spontaneous external gallbladder perforation (author's transl)].

Spontaneous perforation of the gallbladder is one complication of cholelithiasis. There is a greater occurrence of free perforation in the peritoneal cavity with biliary peritonitis, followed by the perforation into the stomach, small intestine and colon. A single case of the nowadays rare spontaneous perforation in and through the abdominal wall will be reported. Spontaneous gallbladder perforation appears nearly asymptomatic in its clinical course because of absent biliary peritonitis.
