Two cases of splenic injury - one after a difficult colonoscopy and the other after routine ERCP - are reported. Splenic injury as a complication of endoscopic procedures is relatively rare, but over the past several years this complication has been increasingly reported. Review of the literature revealed 11 cases occurring after colonoscopy and one after ERCP. Although most of the patients presented with acute abdominal symptoms, some had mild vague symptoms. In two cases the injury was overlooked entirely. Diagnosis was established at laparotomy in four cases, by CT in four, by ultrasonography in two, by chance observation in two, by angiography in one and by paracentesis in one. All patients except the most recent three reported underwent surgery, with one mortality occurring three weeks after the operation.

In a retrospective examination 250 consecutive pancreatograms obtained by ERCP were controlled on the existence of a D. Snatorini. Starting from the genetic development of the pancreatic ducts the question is investigated whether a second open pancreatic duct is responsible for a better drainage of the pancreas. Thus this duct may prevent hyperamylasemia and hyperlipasemia following ERCP. From an etiological point of view the elevation of these pancreatic enzymes is insufficiently understandable. If a D. Santorini is detectable the results demonstrate a reduction of the increased pancreatic enzymes in a statistically significant manner. A valve mechanism of the D. pancreaticus minor with volume or pressure reduction is postulated.
