凡是涉及一个脏器基本结构的研究，不论是大体的、显微镜的、分子的、基因水平或功能状态的研究，都属于临床外科中的基础研究范畴。解剖学研究虽然是外科临床基础研究中最古老的项目，但是随着新科技和临床外科学的发展，又从未间断地添加新的研究内容。例如当前的可视化人体的研究便是个突出的例子。肝、胆管血循环的研究在当代的胆道外科学和移植外科学中占有重要的位置, 而上世纪50年代初期的肝内管道解剖学研究，奠定了现代肝脏外科的基础。
Objective To investigate the new method of pancreaticoenterostomy and decrease the probability of complications like pancreatic fistula etc. Methods By using the absorbable bandage and ear-brain glue, modified sutureless pancreaticoenteromy was made in 10 swines. Experimental data includes： routine analysis of blood, levels of amylase in blood and abdominal drainage and lipase in blood and abdominal drainage. The tissues in anastomosis were taken for pathology examination in 1 month after operation. Results The average operative time was （35±10） min.Nine of ten animals had no pancreatic fistula and survived. The levels of amylase and lipase in abdominal drainage were both normal. One swine had a evident abdominal distensile on 2 days after operation, the level of amylase was 10 000u/L,then died on 10 days after operation. Pancreatic fistula and infection were found because of the loss of stent in pancreatic duct. Conclusions Comparison with traditional operation, the modified sutureless pancreaticoenteromy can also control the probability of pancreatic fistula. And this method can be hoped to be one of the routine operations of pancreaticoenterostomy because of its simplicity and practicality.
