Pancreatic Cancer, Pancreatic Fistula, Periampullary Cancer
Conditions
Brief 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.
Detailed description
Open pancreaticoduodenectomy (PD) was the standard treatment for a wide array of periampullary and pancreatic diseases including malignant and benign conditions. 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 despite several improvements in surgical devices and techniques that have allowed surgeons to approach the pancreas laparoscopically, laparoscopic PD remains challenging. LPD represents one of the most advanced abdominal operations owing to the necessity of a complex dissection and reconstruction. Recent reports note that complete laparoscopic PD including laparoscopic resection and reconstruction is both technically feasible and safe. In this prospective study, investigators evaluate the safety and feasibility of surgical and oncological outcomes of minimally invasive PD.
Interventions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Operative time in minutes | From time of skin incision till time of skin closure | Time spent in surgery |
| Intra-operative blood loss | day 0 (at the end of surgery) | the amount of intra-operative blood loss (ml) at the end of surgery (d0): recorded by the anesthetist using a vacuum system. |
| The rate of pancreatic fistula after pancreaticoduodenectomy | 4 weeks postoperative | On or after the third postoperative day, the drain outflow of any detectable volume was treated as a pancreatic fistula with an amylase content larger than three times the upper normal serum amylase value |
| Amount of intraoperative blood transfusion | From start of surgery of every participant till skin closure | Amount of intraoperative packed red blood cell units transfused intraoperative |
| Length of postoperative surgical intensive care unit stay | From the date of admission to surgical intensive care unit after surgery to the date of discharge to ward or death whichever comes first, assessed up to 3 months . | Length of postoperative surgical intensive care unit stay In days |
| Postoperative length of stay | up to 90 days | the time from being admitted to hospital to discharge |
