Three-dimensional culture in alginate beads, due to its simplicity and reproducibility, was chosen to maintain the pituitary adenoma cells. The procedures included an initial enzymatic digestion and mechanical dissociation of the tumor tissue, and the subsequent cell suspension was encapsulated in alginate beads.

Dermis The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts. Papillary Layer The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

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.
FAQs
Although classified as benign, a duodenal papillary adenoma may contain dysplastic glandular growth and can develop into cancer. That potential makes tissue assessment important rather than relying on appearance alone. Management therefore considers whether malignant change is present or developing, with treatment and follow-up aimed at detecting residual or recurrent disease.
As it enlarges at the papilla, it can interfere with drainage through the bile duct or pancreatic duct. Reduced bile flow may produce jaundice, while impaired pancreatic drainage may contribute to pancreatitis. These effects explain why lesion size and duct anatomy matter when clinicians evaluate symptoms and plan treatment.
Assessment of duct involvement clarifies whether abnormal tissue extends into the channels that drain bile or pancreatic secretions. Endoscopic appearance alone may not show the full anatomic relationship, so clinicians combine direct visualization with tissue sampling and duct assessment. This information helps determine treatment and follow-up according to the lesion’s anatomy.
Treatment selection depends on more than the lesion’s presence. Clinicians consider its size, the histology found in sampled tissue, and its relationship to the bile and pancreatic ducts. When these factors are suitable, endoscopic removal may be considered; other combinations of extent or anatomy may lead to surgery. The same findings also shape subsequent surveillance.
Evaluation combines endoscopic visualization with tissue sampling and assessment of duct involvement. Direct examination identifies the papillary lesion, while sampling helps characterize its epithelial and dysplastic features. Determining whether the bile or pancreatic ducts are involved adds an anatomic dimension that cannot be supplied by histology alone. Together, these findings guide removal approaches and assessment of possible malignant disease.
Follow-up remains important because removal does not eliminate the need to reassess the treated site. Surveillance is intended to detect residual tissue, recurrent disease, or malignant disease after endoscopic removal or surgery. It provides a continuing assessment after initial treatment, helping distinguish successful removal from persistent or returning disease.
