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.

Laparoscopic Anatomic S7+S8d Resection Preserving Inferior Right Hepatic Vein and S6 with Right Hepatic Vein Transection

2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.
FAQs
Protecting the main pancreatic duct and the gland’s blood supply helps the retained parenchyma continue supporting pancreatic function. This matters because the strategy is not simply about leaving tissue behind; it also requires avoiding injury to structures that sustain the remaining gland. These anatomic priorities guide how limited a resection can be while preserving useful tissue.
The central difference is the amount of functioning gland sacrificed during treatment. More extensive resection can remove additional healthy parenchyma along with diseased tissue, increasing the potential effect on endocrine and exocrine function. A tissue-sparing approach instead prioritizes lesion control while retaining viable pancreas, which may reduce postoperative diabetes and pancreatic exocrine insufficiency.
Suitability depends on the nature of the lesion and the patient’s functional risk. The approach is particularly relevant when lesions are benign, premalignant, or low grade, and when future pancreatic disease could make preservation valuable. Surgeons must balance treatment of the diseased area against protection of the main duct, blood supply, and surrounding healthy parenchyma.
Limited resections and enucleation are examples of procedures that can target pancreatic lesions while retaining more surrounding gland. The selected option depends on how the diseased tissue relates to the remaining parenchyma, the main pancreatic duct, and its blood supply. These approaches support individualized surgery when removing the entire relevant portion of the pancreas would sacrifice unnecessary healthy tissue.
Planning begins by considering the lesion’s characteristics alongside the patient’s risk of losing pancreatic function. Surgeons then select a tissue-sparing option, such as a limited resection or enucleation, while accounting for the main duct, blood supply, and surrounding parenchyma. This individualized process aims to remove or treat the diseased tissue without making the operation more extensive than necessary.
Retaining healthy glandular tissue can help maintain both endocrine and exocrine pancreatic function after surgery. In practical terms, this may reduce the likelihood of postoperative diabetes and pancreatic exocrine insufficiency compared with sacrificing more parenchyma. The principle is especially relevant for patients who may face future pancreatic disease, because preserved tissue can remain important to later functional reserve.
