“…1) according to the different potential of malignant transformation. [23] In groups 3 to 5, where over 89% of the cystic lesions were malignant, POP had a sensitivity of 68% and a specificity of 87% detecting malignancy. When using POP additional diagnostic information affecting clinical decision-making was found in 76% of the patients by Arnelo et al The sensitivity was 84% and the specificity 75% for identifying malignant lesions.…”

“…[26] Adding IDUS to POP is especially beneficial in the evaluation of branch duct lesions, where the accuracy of differentiating benign and malignant lesions increased from 67% with POP alone to 88% for POP with IDUS. [23] Preoperative POP adds valuable information for preoperative surgical planning. According to Tyberg et al preoperative POP changed the surgical plan in 62%, with a very high correlation (88%) between POP and final histology.…”

The natural connection between the duodenum and the pancreatic duct enables a minimally invasive access to the pancreas. Endoscopically this access is already regularly used, mainly for diagnostic and even for certain therapeutic purposes. With per-oral pancreatoscopy the endopancreatic approach allows the direct visualization of the pancreatic duct system potentially improving the diagnostic work-up of pancreatic cystic neoplasms, intrapancreatic strictures and removal of pancreatic duct stones. However, the endopancreatic access can equally be applied for surgical interventions. The objective of this review is to summarize endoscopic and surgical interventions using the endopancreatic access. Endopancreatic surgery stands for a further development of the endoscopic technique: a rigid endoscope is transabdominally introduced over the duodenum and the papilla to enable resections of strictures and inflamed tissue from inside the pancreas under visual control. While the orientation and localization of target structures using this minimally invasive approach is difficult, the development of an accurate image guidance system will play a key role for the clinical implementation and widespread use of endoscopic and surgical endopancreatic interventions.
