Laparoscopic Pancreaticoduodenectomy

Condition(s) studied

Investigational drug(s) / intervention(s)

laparoscopic Pancreaticoduodenectomy: The patient is positioned in French position (right arm in, left arm abducted 90°), with a suprapubic area reserved for Pfannenstiel incision. A 6-port technique is used: sub-umbilical (12 mm), four semi-circular trocars (two 12 mm, two 5 mm), and a sub-xiphoid trocar for liver retraction. Laparoscopic pancreaticoduodenectomy (LPD) proceeds if no vascular invasion/metastasis is found. Key steps include Kocher's maneuver, vessel ligation (gastroepiploic, gastric, gastroduodenal), lymphadenectomy (stations 5-17), pancreatic neck transection, and jejunal division. Reconstruction involves duct-to-mucosa pancreaticojejunostomy (or invaginating if duct unfound), hepaticojejunostomy, and stapled gastrojejunostomy. Margins are examined post-resection. Harmonic scalpel/Ligasure and staplers are used.

Study summary

Laparoscopic pancreaticoduodenectomy was first performed by Garner and Pomp in 1994. This is a technically difficult, time consuming and high rate of complication procedure. The reason is that duodenum and head of pancreas locate deeply in retroperitoneum and are surrounded by important structures such as inferior vena cava, abdominal aorta, superior mesenteric artery, superior mesenteric vein (SMV), portal vein (PV) and hepatic arteries. Injuring these structures during the surgery can lead to life-threatening complications. Moreover, doing anastomoses through laparoscopy, especially pancreatic anastomosis, is more difficult and takes more time than through open approach. The outcome of PD has improved over the last two decades due to advances in surgical techniques, anesthesia and perioperative care. Although studies from high volume centers demonstrate reduce in the operative mortality to less than 3%, the postoperative morbidity rate is still ranging from 30% to 60%. Laparoscopic surgery is being used increasingly as a less invasive alternative to traditional interventions for pancreatic resection. Laparoscopic pancreaticoduodenectomy (LPD) is a difficult procedure that has become increasingly popular. Nevertheless, comparative data on outcomes remain limited. In this prospective study, investigators evaluate the safety and feasibility of surgical and oncological outcomes of minimally invasive PD.

Eligibility

Primary outcome measure(s)

• Pathological Assessment of Surgical Specimens — Assessed at the time of surgical specimen pathological evaluation (typically within 1-2 weeks post-surgery).
  Evaluation of the surgical specimens will include: * Number of lymph nodes harvested: Total count of lymph nodes excised and examined during surgery. * Resected margin status: Assessment of the presence or absence of tumor cells at the resection margins, classified as negative (R0), microscopic positive (R1), or macroscopic positive (R2). * Ratio of positive lymph nodes to total lymph nodes harvested: Proportion (%) calculated by dividing the number of histopathologically confirmed metastatic lymph nodes by the total number of lymph nodes retrieved.
