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.

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”. Morphological Manifestations of Necrosis Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Robotic pancreatoduodenctomy (RPD) has been highly standardized in recent years and may be used in selected patients with pancreatic head cancer, including those with a replaced right hepatic artery. This case report describes a standardized and reproducible technique for RPD, which includes the approach of the Dutch LAELAPS-3 training program to an aberrant vasculature.

Source: Chen, Y. et. al., Evaluating Virulence and Pathogenesis of Aeromonas Infection in a Caenorhabditis elegans Model. J. Vis. Exp. (2018)This video demonstrates a muscle necrosis assay in C. elegans (Caenorhabditis elegans) using pathogenic Aeromonas strains. By feeding green fluorescent protein (GFP)-expressing worms on Aeromonas-seeded plates, the assay models bacterial infection and reveals tissue damage through fluorescence imaging. The progressive loss of muscle structure and GFP...
FAQs
Impaired blood flow reduces the tissue’s ability to withstand inflammatory injury, while pancreatic enzymes promote autodigestion, meaning breakdown of pancreatic tissue by its own enzymes. Together, these mechanisms can intensify local damage in the pancreatic head during acute pancreatitis. Understanding this interaction helps clinicians interpret necrosis as an active inflammatory and vascular injury process, not simply an imaging finding.
Necrosis can remain sterile or become infected, and that distinction changes the clinical concern and treatment plan. Suspected infection is important because it supports considering antibiotics, whereas sterile disease may be managed according to the patient’s overall condition without assuming infection. Clinicians therefore interpret the tissue state alongside symptoms and imaging rather than treating every area of necrosis as infected.
Contrast-enhanced imaging helps show how much pancreatic tissue is affected and whether fluid collections accompany the necrosis. This information adds anatomical detail to the clinical assessment, allowing clinicians to characterize the local complication rather than relying on symptoms alone. Defining the extent and associated collections also helps place the patient’s condition within the broader management decision, including whether drainage or debridement may be relevant.
Clinical findings provide the patient-level context that imaging cannot establish by itself. When combined with contrast-enhanced imaging, they help clinicians assess the significance of the necrotic process, recognize a potentially severe complication of acute pancreatitis, and judge urgency. This combined assessment supports risk evaluation and helps guide whether care should remain supportive or progress toward intervention.
Management begins with supportive care tailored to the patient’s condition and includes nutritional support. Antibiotics are not presented as automatic treatment; they are used when infection is suspected. This approach addresses the patient’s immediate needs while clinicians continue evaluating the necrosis and any associated collections, which may determine whether additional drainage or debridement becomes necessary.
Drainage or debridement may be considered when the patient’s condition and local findings indicate that procedural management is appropriate. Available approaches can include minimally invasive procedures or surgery, depending on the clinical situation. Choosing among these options requires assessment of the patient’s overall condition, the extent of necrosis, and the presence of associated fluid collections.
