Surgical approaches for resection of pancreatic cancer: an overview.

OBJECTIVE: To overview the different surgical approaches for the resection of pancreatic cancer and our experience with these techniques. METHODS: Surgical procedures including the Whipple resection, Pylorus-preserving resection, total and subtotal panreatectomies, regional pancreatectomy and the extended lymph node resection were discussed. RESULTS: Studies have shown that no operation seems to produce significantly improved results in terms of survival, mortality and resection rates compared to the standard Whipple resection and pylorus-preserving duodenopancreatectomy. CONCLUSION: Despite the progress in the surgical treatment of pancreatic cancer, the overall prognosis after resection remains unsatisfied. Surgery is likely to be optional for the treatment of pancreatic cancer.

Solving geometric constraints with genetic simulated annealing algorithm.

This paper applies genetic simulated annealing algorithm (SAGA) to solving geometric constraint problems. This method makes full use of the advantages of SAGA and can handle under-/over- constraint problems naturally. It has advantages (due to its not being sensitive to the initial values) over the Newton-Raphson method, and its yielding of multiple solutions, is an advantage over other optimal methods for multi-solution constraint system. Our experiments have proved the robustness and efficiency of this method.
