Risk factors of hyperamylasemia in patients with gastrointestinal minimally invasive surgery / 中国综合临床

ABSTRACT

Objective To investigate the risk factors of hyperamylasemia in patients with gastrointestinal minimally invasive surgery.Methods Two hundred and twenty cases with gastrointestinal were selected as our subjects who were hospitalized in General Surgery Department of the Center Hospital of Binzhou from Jan 2012 to Jan 2014.The patients were divided into normal group and hyperamylasemia group according to the postoperative serum amylase levels.The complications of two groups were recorded.The risk factors of hyperamylasemia were analyzed with univariate and Logistic multivariate.Results There were 98 cases (44.54％,98/220) of concurrent hyperamylasemia,45 cases (20.45 ％) of colon surgery,53 cases (24.09％) of stomach surgery.The complications of hyperamylasemia group and normal group were 28 cases (28.57％) and 8 cases (6.56％),and the difference was significant (x2 =4.869,P =0.006).Univariate analysis showed that there were significant differences in terms of the abdominal surgery,surgical approach,body mass index ＞ 25 kg/m2,operation time,position,CO2 insufflation pressure,pneumoperitoneum duration and pancreatic treatment between two groups(P ＜ 0.05).Logistic multivariate analysis showed that the abdominal surgery,CO2 insufflation pressure,pneumoperitoneum duration and operative time were independent risk factors with hyperamylasemia.Conclusion There is high incidence of hyperamylasemia after laparoscopic gastrointestinal surgery.Patients with pancreatitis and postoperative infection are easily to get hyperamylasemia complications.Upper abdominal surgery,CO2 insufflation pressure,pneumoperitoneum duration,operative time are independent risk factors for hyperamylasemia.
