Abstract:Objective To investigate the clinical effects and safety of peritoneal lavage and continuous circular peritoneal dialysis (CCPD) after laparoscopic operation in treatment of severe acute pancreatitis (SAP). Methods 68 patients of SAP were randomly divided into treatment group and control group. 32 cases of treatment group were performed laparoscopic operation, and then treated with peritoneal lavage and continuous circular peritoneal dialysis alternatively. When the patient's condition was stable and serum amylase reduce to normal, only peritoneal lavage was used in the treatment. 36 cases of control group were treated with regular methods. Results The operation time, the hemorrhage amount of operation, the recovery time of serum index and the incidence of complication after operation were significantly decreased compared with those of the contrast group. The CT scores and APACHEⅡscores were significantly decreased on the first day in microtraumatic group and on third day in control group, and the scores on each observation point in microtraumatic group were lower than those in control group. The serum levels of proinflammatory cytokines TNF-α、IL-6、IL-8 and CRP were significantly decreased and the serum level of antiinflammatory cytokines IL-10 was significantly increased significantly after treatment in both groups. But the serum TNF-α、IL-6、IL-8 and CRP levels were higher and the serum IL-10 level was lower on each observation points in microtraumatic group than those in control group. Conclusions Peritoneal lavage and continuous circular peritoneal dialysis after laparoscopic operation is a simple, safe, quick, less traumatic, few complicated, no anticoagulant, easy tolerated and effective method in the treatment of severe acute pancreatitis.
