Imbedding pancreaticojejunostomy used in pure laparoscopic pancreaticoduodenectomy for nondilated pancreatic duct

Backround LPD has been cautiously regarded as feasible and safe for resection and reconstruction. However, anastomosis of the remnant pancreas is still thought to be a critical obstacle to the dissemination of LPD in general practice. This study presents a new technique of pancreaticojejunostomy for nondilated pancreatic duct and evaluates its safety and reliability. Methods From July 2014 to June 2015, a total of 52 patients underwent LPD with the new technique. A modified technique of duct-to-mucosa PJ was performed with transpancreatic interlocking mattress sutures, named the imbedding duct-to-mucosa PJ. Then the morbidity and mortality was calculated. Results This technique was applied in 52 patients after LPD all with nondilated pancreatic duct (1-3 mm). The mean operation time was 4.6 h (range, 3.5-8.3 h) and the median time for the anastomosis was 37 min (range, 24-53 min). Operative mortality was zero, and morbidity was 21.2 % (n = 11), including hemorrhage (n = 3, 5.8 %), biliary fistula (n = 1, 1.9 %), pulmonary infection (n = 1, 1.9 %), delayed gastric emptying (n = 2, 3.8 %), abdominal abscess caused by biliary fistula or PF formation (n = 2, 3.8 %), and POPF (n = 2, 3.8 %). Two patients developed a pancreatic fistula (one type A, one type B) classified according to the International Study Group on Pancreatic Fistula. Conclusions The described technique is a simple and safe reconstruction procedure after LPD, especially for patients with nondilated pancreatic duct.
