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
Kocherization changes the operative relationship of the duodenum and pancreatic head to the posterior abdominal structures. After the lateral peritoneal attachment is released, these structures can be dissected medially, opening a pathway to tissues that are otherwise hidden behind them. This altered position allows direct assessment of deeper vascular, renal, and posterior duodenal regions.
The lateral peritoneal reflection marks the operative entry point for mobilization. Incising along the duodenum permits the surgeon to separate the duodenum and pancreatic head from their lateral attachment while preserving the intended medial movement. The resulting plane determines how much retroperitoneal anatomy becomes accessible and supports controlled exposure rather than indiscriminate dissection.
The extent can be matched to the clinical objective. Limited mobilization may provide focused access to the immediate posterior duodenal or pancreatic region, whereas broader mobilization opens more of the retroperitoneum. This flexibility lets the surgeon adjust exposure for evaluation, hemorrhage control, or operative work without treating every case as requiring the same dissection.
The maneuver can expose the inferior vena cava, aorta, right renal region, and posterior tissues of the duodenum. It also improves access around the pancreaticoduodenal region by moving the overlying structures medially. Examining these areas can help determine the location and extent of retroperitoneal or adjacent injury and guide the next operative step.
In abdominal trauma, Kocherization supports direct assessment of suspected injury involving the duodenum, pancreatic head, or nearby retroperitoneal structures. The exposure can also help the surgeon evaluate and control hemorrhage in deeper regions. Its adjustable extent is relevant when the initial clinical objective requires either focused inspection or wider retroperitoneal access.
Operations involving the pancreaticoduodenal region may require more than surface inspection because important tissues lie posterior to the duodenum and pancreatic head. Medial mobilization provides access for assessment and operative management in that area, while the chosen extent of dissection can be tailored to the specific procedure, suspected injury, or need for hemorrhage control.
