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.

Robotic Duodenal Sleeve Resection for Gastrointestinal Stromal Tumor with Rare Exon 8 KIT Mutation Following Neoadjuvant Imatinib
0 Views •
2026
This video case report demonstrates the unique management of a duodenal gastrointestinal stromal tumor with a rare, understudied, exon 8 KIT mutation. Neoadjuvant therapy resulted in a 30% reduction in tumor size, making the patient a candidate for a robotic-assisted duodenal sleeve resection instead of the more morbid pancreaticoduodenectomy.
FAQs
Maintaining duodenal continuity and its blood supply limits disruption of normal anatomy around the pancreatic head. This preservation is intended to support digestive physiology rather than replace the duodenum with a surgically altered pathway. The approach therefore balances removal of diseased pancreatic tissue with continued conservation of an important digestive structure.
When pancreatic duct obstruction contributes to the disorder, decompression can be performed alongside removal of abnormal tissue from the pancreatic head. Addressing the duct provides a way to relieve obstruction while retaining the duodenum. Its use is conditional, so the operative plan depends on whether ductal decompression is necessary for the individual disease pattern.
Its distinguishing principle is selective treatment of the pancreatic head while retaining duodenal continuity and blood supply. Compared with an approach that causes greater disruption of surrounding digestive anatomy, this strategy aims to conserve more normal structure. That anatomical preservation may help maintain digestive function while still addressing localized inflammatory or pathological tissue.
The surgeon first accesses the diseased region of the pancreatic head and cores or excises inflammatory or pathological tissue. If pancreatic duct obstruction requires treatment, the duct is decompressed during the operation. Throughout the procedure, the surgeon preserves the duodenal blood supply and continuity, combining local disease removal with anatomical conservation.
The procedure is used mainly for chronic pancreatitis and selected benign or low-grade lesions. Suitability depends on the disease being localized to the pancreatic head and on the clinical need for surgery. Pain, pancreatic duct obstruction, or a localized pathological process can provide the rationale for considering this tissue-preserving approach.
The operation is intended to relieve symptoms such as pain, address pancreatic duct obstruction when present, and control localized disease. At the same time, retaining the duodenum may support digestive physiology by preserving its continuity and blood supply. These goals explain why the procedure can be relevant when treatment is needed without removing more normal anatomy than necessary.
