RESUMEN
Objective To study the effects of different intervention time of percutaneous transhepatic gallbladder catheterizing drainage (PTGBD)on severe acute biliary pancreatitis Methods Totally 64 patients with severe acute biliary pancreatitis in Affiliated Hospital of Hebei University from July 2013 to July 2017were selected and divided into 3 groups according to the time from attack to PTGBD:group A (less than 72 hours,n =28),group B (from 72 hours to 120 hours,n =22),group C (from 120 hours to 148 hours,n =14).Intergroup comparison of level of WBC,CRP,TBIL,PLT and APACHE-Ⅱ Score,disappearance time of abdominal sign,incidence of pancreatic abscess,length of stay (LOS),mortality and patient satisfaction 48 hours before and after PTGBD were conducted.Results Compared with those in group B and C,all laboratory indexes,APACHE-ⅡScore,disappearance time of abdominal sign,incidence of pancreatic abscess,LOS,mortality and patient satisfaction in group A were all significantly different (P ＜ 0.05).Conclusion Early PTGBD (within 72 hours)can be effective and safe for the treatment of severe acute biliary pancreatitis,and can shorten LOS and reduce the mortality.
