ABSTRACT
Objective To explore perioperative risk factors for postoperative pancreatic fistu?la. Methods Six hundred and forty?three cases patients who underwent radical gastrectomy for gastric cancer from January 2010 to June 2015 in the NO. 309 Hospital of Chinese People’ s Liberation Army were selected and divided into Postoperative Pancreatic Fistula( POPF) group with 53 cases and Non?Postoperative Pancreatic Fis?tula( NPOPF) group with 590 cases. Preoperative,intraoperative and postoperative data were analyzed by statisti?cal analysis of two groups. Results POPF rate was 8. 24%(53/643). There were no significanct differences in terms of gender,age,preoperation with disease,preoperative serum albumin,TNM stage,abdominal surgery,sur?gical procedure,lymph node dissection,digestive tract reconstruction,surgical approach,blood loss and length of time between the POPF group and NPOP group(P>0. 05). The level of BMI of POPF group was higher than that of NPOPF group,the difference was statistically significant((25. 63±2. 54) kg/m2 vs. (21. 11±2. 44) kg/m2,t=2. 245,P=0. 025). The number of lymph node dissection in POPF group was (32. 25±5. 82),in NPOPF group was (27. 06±6. 79),there was significant difference between the two groups(t=2. 093,P=0. 037). The operation time in POPF group was (242. 50±52. 30) min,in NPOPF group was (229. 51±59. 21) min,the difference was statistically significant between the two groups( t=2. 398,P=0. 017) . The serum CRP of 1 d in POPF group was (85. 72±12. 05) mg/L,in NPOPF group was (76. 41±12. 52) mg/L,and there was significant difference between the two groups( t=1. 979,P=0. 048) . The serum albumin of 2?4 d after operation in POPF group was (26. 0±5. 9) g/L,in NPOPF group was (32. 6±6. 8) g/L,the difference between the two groups was statistically significant(t=-10. 185,P=0. 000). The drainage fluid amylase of 1 and 2 d after operation in POPF group was (2094+1444) U/L,in NPOPF group was (746+486) U/L,and there was significant difference be?tween the two groups( t=10. 400,P=0. 000) . Logistic regression analysis results showed that body mass index ( BMI) ,lymph node dissection number,time of operation,postoperative 1,2 d drainage fluid amylase and serum albumin of 2?4 d after operation were postoperative occurred pancreatic fistula risk factors( OR=1. 972,183. 6, 2. 004,0. 150,9. 809,P>0. 05). Conclusion BMI,number of dissected lymph node,duration of surgery,serum albumin of 2?4 d after operation and postoperative 1,2 d drainage fluid amylase have important clinical values for predicted POPF.
