2026
This protocol presents robotic duodenum-preserving total pancreatic head resection (R-DPPHRt) for intraductal papillary mucinous neoplasms (IPMNs). A video demonstrates the technique in a patient with main duct-IPMN, highlighting its feasibility as a minimally invasive, organ-preserving alternative to pancreaticoduodenectomy.

Using Unfixed, Frozen Tissues to Study Natural Mucin Distribution

Unfixed frozen tissue samples embedded in Optimal Cutting Temperature medium (OCT) can be used to study natural distribution and glycosylation of secreted mucus. In this approach tissue processing is minimal and the natural presentation of glycolipids, mucins and glycan-epitopes is preserved. Tissue sections can be analyzed by immunohistochemistry using fluorescence or chromogenic detection.

Mucin Agarose Gel Electrophoresis: Western Blotting for High-molecular-weight Glycoproteins

Mucins are high-molecular-weight glycoconjugates, with size ranging from 0.2 to 200 megadalton (MDa). As a result of their size, mucins do not penetrate conventional polyacrylamide gels and require larger pores for separation. We provide a detailed protocol for mucin agarose gel electrophoresis to assess relative quantification and study polymer assembly.

Microscopic Cyst Resection for the Treatment of Patients Diagnosed with Epididymal Cyst
0 Views •
2023
Here, we present a protocol to treat patients diagnosed with an epididymal cyst using microscopic cyst resection. Based on microscopic manipulation, a largely improved visualization of the subtle tissue structures of the epididymis was obtained, so the cyst could be clearly dissected apart and completely removed intact.
FAQs
Mucin can alter risk by accumulating within pancreatic ducts and contributing to obstruction. In duct-based lesions, this mechanical effect is clinically important because it can change duct anatomy while the underlying neoplastic process may progress toward invasive pancreatic cancer. Recognizing the relationship between mucin, duct involvement, and progression supports closer risk assessment rather than treating every cyst identically.
Duct communication is a key discriminator because it links a cystic lesion to the pancreatic duct system, a pattern associated with intraductal papillary mucinous neoplasms. A mucinous cystic neoplasm instead typically presents as a separate cystic mass. Establishing this relationship helps clinicians classify the lesion accurately and select an appropriate balance between surveillance and surgical removal.
Cross-sectional imaging contributes more than a simple cyst survey: it helps assess the lesion’s relationship to pancreatic ducts and identify wall features that may affect concern. Endoscopic ultrasound can provide a closer evaluation, while cyst-fluid cytology and molecular markers add biologic information. Combining structural and fluid-based findings improves characterization when no single observation is decisive.
Evaluation generally combines cross-sectional imaging with endoscopic ultrasound and, when obtained, cyst-fluid analysis. Imaging examines duct communication and wall features; endoscopic ultrasound further supports lesion assessment; cytology evaluates cells, and molecular markers contribute additional characterization. This multimodal approach is useful because classification depends on integrating anatomical and cyst-content information rather than relying on a single category of evidence.
Cyst-fluid cytology and molecular markers address different characterization needs. Cytology examines the cellular material present in the fluid, whereas molecular markers provide another type of lesion-related signal. Used alongside imaging findings, these analyses can help identify clinically important patterns and improve classification, which is central to deciding whether surveillance or surgical removal is more appropriate.
Risk-based management weighs the possibility of progression against the need to avoid unnecessary procedures. Surveillance can monitor lesions judged appropriate for observation, whereas surgical removal can prevent progression when risk warrants intervention. The goal is not to operate on every mucinous cyst, but to match management to lesion classification and concerning findings while addressing the risk of invasive pancreatic cancer.
