Summary

Pancreaticoduodenectomy (PD) is one of the most complicated surgical procedure and one of the standard treatments for benign and malignant disease of pancreatic head and periampullary region. Improvements in surgical techniques and the perioperative management of patients undergoing PD have reduced the surgical mortality rates to less than 3% in high-volume medical centers. However, the incidence of postoperative complication remains high, which ranges from 30% to 50% and the pancreatic fistula rate ranges from 5% to 40%. The key point of PD is still the enteric reconstruction of pancreatic stump. There were different techniques of enteric reconstruction, including: invagination pancreaticojejunostomy, binding pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy, Roux-en-Y pancreaticojejunostomy, and pancreaticogastrostomy and each technique had its advantages and disadvantages. We established a new digestive reconstruction technique named shark mouth modified pancreaticojejunostomy, which had theoretical advantages including easier performed; lower tension and less complication. The shark mouth modified pancreaticojejunostomy is an end-to-end pancreaticojejunostomy procedure which is between invagination pancreaticojejunostomy and binding pancreaticojejunostomy.The remnant of jejunum is shaped as shark mouth and then sutured with the pancreas remnant. After the surgery, the patients will be well followed up. The pancreaticojejunostomy time, post-operation complication, mortality and hospital stay will be documented to study the safety, efficiency and advantage of this new procedure.

PROCEDURE

Shark Mouth Modified Pancreaticojejunostomy

The remnant of jejunum is closed by continuous suture. The transverse incision is made on the posterior wall of the jejunum (5 centimeters distal to remnant）, which starts at 0.2 centimeter to the mesenteric border and should never exceed the anti-mesenteric border . In case of large pancreas remnant, a longitudinal jejunum incision will be done at anterior part of anastomosis. The posterior part of anastomosis is two layers of intermittent suture, including seromuscular suture layer and full thickness suture layer. The anterior part of anastomosis is a single layer full thickness suture. At last, the seromuscular layer of the proximal jejunum is sutured with the anterior pancreatic capsule to cover the anterior part of anastomosis.
