Laparoscopic pancreaticoduodenectomy is an important surgical undertaking, mostly used for benign and malignant tumors in the pancreatic head and periampullary region. The postoperative pancreatic fistula is the main factor to cause death after pancreaticoduodenectomy, and pancreaticojejunostomy is an independent risk factor for pancreatic fistula. In order to reduce the incidence of pancreatic fistula, surgeons have proposed dozens of pancreaticojejunostomy, but so far there are no randomized trials proved which method of pancreaticojejunostomy is better than the others. This article reviews the methods and characteristics of different pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.

Objective To investigate the effect of Akt pathway inhibitor AZD5363 on cell proliferation and invasion of QBC939 and RBE cholangiocarcinoma cells and the mechanism.Methods Western blotting was used to detect Akt and downstream protein and mTOR protein expression in two cancer cell lines after process by AZD5363.Inhibition rate and cytotoxicity was tested by CCK-8 assay,and Transwell assay was used to evaluate the invasive ability of cancer cells.Results QBC9393 cell exposed to AZD5363 LD50 drug concentration (24 ±9) was significantly different compared with control group (t =4.47,P < 0.05),RBE cells LD50 drug concentration (21 ± 8) was significantly different compared with control (t =4.41,P < 0.05).Tumor invasion capacity of QBC939 in drug concentrations of 20 μmol/L (63 ± 12) and 0 μmoL/L (271 ± 27),the difference was statistically significant.RBE exposed AZD5363 upon drug concentrations of 20 μmol/L (58 ± 23) and 0 μmol/L (235 ± 21),the difference was statistically significant.AZD5363 promotes phosphorylation of mTOR in QBC939.Conclusions AZD5363 inhibits the proliferation and migration,inhibiting the phosphorylation of Akt and its downstream molecules.AZD5363 promotes phosphorylation of mTOR in QBC939.
