Superior Mesenteric Artery First Versus Standard Approach in Pancreaticoduodenectomy

"Pancreatic cancer, especially pancreatic ductal adenocarcinoma, is one of the most serious and deadly cancers. Its outlook is very poor, with fewer than 10% of patients surviving five years after diagnosis. This is largely because the disease is often discovered at a late stage and because it frequently comes back even after surgery. When the tumor is located in the head of the pancreas, the only treatment that can potentially cure the disease is a major operation called a pancreaticoduodenectomy, also known as the Whipple procedure. This surgery is now safely performed in specialized hospitals, but it remains complex and carries a high risk of complications. Importantly, even after surgery, cancer cells often remain, leading to a high rate of local recurrence. A newer surgical technique, known as the "artery-first" approach, changes the order of the operation. By carefully exposing a major blood vessel near the pancreas at the beginning of the surgery, surgeons can better assess whether the tumor can be completely removed and can improve the precision of the operation. This research protocol aims to compare this artery-first technique with the standard surgical approach. The goal is to determine whether starting the operation by addressing the artery allows for more complete tumor removal and reduces the risk of cancer coming back in patients with pancreatic cancer of the head of the pancreas."

Impact of Intraoperative PTCD Catheter Retention Versus Removal on Postoperative Short-term Outcomes After Pancreaticoduodenectomy in Obstructive Jaundice

Pancreaticoduodenectomy (PD) is a complex surgical procedure commonly performed for tumors of the pancreatic head and periampullary region. Many patients present with obstructive jaundice and undergo preoperative percutaneous transhepatic cholangial drainage (PTCD) to relieve biliary obstruction. However, there is currently no consensus on whether the PTCD catheter should be removed or retained during surgery. This multicenter, prospective randomized controlled trial aims to compare two intraoperative strategies: removal versus retention of the PTCD catheter during PD. Participants will be randomly assigned to either group. The study will evaluate whether these different approaches influence postoperative outcomes, particularly major complications such as bile leak and severe postoperative morbidity within 90 days after surgery. In addition to complications, the study will assess recovery after surgery, including return of gastrointestinal function, length of hospital stay, and quality of recovery, as well as laboratory indicators of liver function and inflammation. The results of this study are expected to provide evidence to guide surgical decision-making regarding PTCD management during PD and to improve patient outcomes.

Prognostic Outcomes of Total Mesopancreas Excision for Pancreatic Head Cancer

Pancreatic ductal adenocarcinoma (PDAC) has poor prognosis due to high recurrence rates after standard pancreaticoduodenectomy (PD). The concept of Total Mesopancreas Excision (TMpE), analogous to total mesorectal excision, aims to improve oncological outcomes by achieving higher R0 resection rates through the comprehensive removal of retroperitoneal connective tissue surrounding major peripancreatic vessels. This single arm prospective study will evaluate the prognostic outcomes, primarily Disease- Free Survival (DFS) at 24 months, of a standardized TMpE technique performed during pancreaticoduodenectomy for resectable pancreatic head cancer. Secondary objectives include assessing Overall Survival (OS), R0 resection rates, recurrence patterns, and perioperative outcomes in 90 consecutive patients.
