Objective To analyse clinical efficacy of Frey and Bger procedures for chronic pancreatitis. Methods Clinical data of seventy patients of chronic pancreatitis undergoing Frey (32 cases) and Beger Procedures (38 cases) in our hospital from January 1999 to June 2009 were retrospectively analyzed,the rate of pain relief and endocrine and exocrine function of the pancreas in longterm follow-up were compared with each other. Results Overall perioperative morbidity for Frey group and Beger group was 12. 5% and 7.9% respectively (P =0. 52); Total pain relief rate in long-term follow-up was 96. 8% and 94. 7% respectively (P =0. 57). Postoperative de novo diabetes mellitus was 12. 5% and 21% ( x2 = 0. 90, P = 0. 34), Rate of steatorrhea was 12. 5% and 18.6% respectively ( x2 = 0. 15, P =0. 70). Conclusions Frey and Beger procedures were equally effective in improving symptoms of chronic pancreatitis and there were no significant differences in perioperative morbidity, rate of pain relief and function of endocrine and exocrine of the pancreas.
