Duodenal perforations during ERCP are associated with high morbidity and mortality
rates. Traditionally, duodenal perforations caused by the duodenoscope itself (Stapfer
type I) have been treated surgically. The OTSC is already recommended for the treatment
of iatrogenic perforations, but there is scarce data about its use related to ERCP-related
duodenal perforations.
We present the case of a 91-year-old man, diagnosed with pancreatic head cancer, who
underwent biliary stenting through ERCP. During the removal of the prophylactic pancreatic
stent, a full-thickness defect of 20mm diameter was visible in the superior duodenal
flexure. An OTSC successfully closed the perforation without further intervention.
