Objective To analyze the difference in the incidence of postoperative pancreatic leakage and anasto-motic bleeding complications in various methods of pancreaticojejunostomy after pancreaticoduodenectomy (PD).
Methods The clinical data of 526 patients underwent pancreaticojejunostomy from January 2008 to September 2012 in this hospital were analyzed retrospectively. End-to-side “pancreatic duct to jejunum mucosa-to-mucosa” anastomosis (abbreviation:mucosa-to-mucosa anastomosis) was performed in 359 patients, which contained 149 patients with internal drainage, 130 patients with external drainage, and 80 patients with no drainage. End-to-side invaginated anastomosis was performed
in 165 patients without drainage. In addition, side-to-side anastomosis was performed in 2 patients without drainage.
Results There were 34 cases (6.46%) of pancreatic leakage, 8 cases (1.52%) of anastomotic bleeding in pancreaticoje-
junostomy, and 32 cases of death (6.08%). ① The pancreatic leakage rate of mucosa-to-mucosa anastomosis was signi-
ficantly lower than that of end-to-side invaginated anastomosis 〔4.18% (15/359) versus 11.52% (19/165), χ2=10.029, P=0.002〕. There was no significant difference of the anastomotic bleeding incidence between mucosa-to-mucosa anasto-
mosis and end-to-side invaginated anastomosis 〔1.67% (6/359) versus 1.21% (2/165), χ2=0.159, P=0.691〕. ② In the mucosa-to-mucosa anastomosis group, the pancreatic leakage rates in the ones with internal drainage and external drainage were lower than those in the ones without drainage, respectively (2.68% (4/149) versus 11.25% (9/80), χ2=7.132, P=
0.008;1.54% (2/130) versus 11.25% (9/80), χ2=9.410, P=0.002);which was no significant difference between the ones with internal drainage and external drainage 〔2.68% (4/149) versus 1.54% (2/130), χ2=0.433, P=0.510〕. But there were no significant differences for both the pancreatic leakage 〔2.68% (4/149) versus 1.54% (2/130), χ2=0.433, P=0.510〕and anastomotic bleeding incidence 〔2.68% (4/149) versus 1.54% (2/130), χ2=0.433, P=0.510〕 between the ones with internal drainage and external drainage.
Conclusions Mucosa-to-mucosa anastomosis has a lower pancreatic leakage incidence as compared with end-to-side invaginated anastomosis. However, there is no significant difference of the anast-omotic bleeding incidence. Internal or external drainage could reduce the incidence of pancreatic leakage, but have no obvious effect to the anastomotic bleeding incidence.
