Postoperative Complications

Early postoperative complications with CP patients include postoperative bleeding，pancreatic fistula，intestinal fistula and infections.The morbidity rate has been decreased these years due to improved surgery skills.However，for patients who undergo the pancreatectomy，insufficient endocrine function is common after operation，causing frequently occurrence of Ⅲc diabetes and diarrhea.As some studies reported，the cumulative incidence of new-onset diabetes millitus after distal pancreatectomy was fairly high（De Bruijn and van Eijck 2015）and the incidence depended on the preexisting disease，pancreatic resection range and follow-up time.Besides，to some extent，the removal position is correlated with the insufficient endocrine or exocrine functions.Generally speaking，proximal pancreatectomy makes negative effect on exocrine function，but distal pancreatectomy reduces endocrine function.(https://www.daowen.com)

The surgical procedures for CP patients are various，with no single procedure suitable for every patient，and the outcome of operation remains individual-specific.To achieve optimal surgical results，surgeons should sufficiently evaluate the patient's clinical features，auxiliary examination results，and history of treatments to develop an individualized surgical option.Besides，preoperative diseases or customs，such as alcohol addiction，which will affect postoperative morbidity，must be solved to attain satisfying operation effect.
