Abstract: Objective To compare wedge biopsy and disposable automatic biopsy gun biopsy for the diagnosis of pancreatic cancer. Methods The clinical data of 217 patients with unresectable pancreatic cancer undergoing palliative operation and biopsy were retrospectively analyzed in our hospital from March 25,2006 to March 25,2011.Group A(wedge biopsy) consisted of 120 cases and B( disposable automated biopsy gun biopsy) of 97 cases.The success rate of biopsy,the positive rate of biopsy,the accuracy of diagnosis and the incidence of postoperative complications were calculated. Results The success rate,positive rate,diagnostic accuracy and the incidence of postoperative hemorrhage of group A and B were 100％,97.5％,97.5％,1.7％ and 100％,99％,99％,1.0％,respectively ( all P ＞ 0.05 ).The incidence of postoperative pancreatic leakage in group A and B were 11.7％ and 2.1％ (P =0.007 ).Conclusions Intra-operative biopsy for the diagnosis of pancreatic cancer using disposable automated biopsy gun biopsy has significantly decreased the incidence of post-biopsy pancreatic leakage as compared with wedge biopsy.
