Abstract:
Objective To investigate the influence of laparoscopic cholecystectomy (LC)versus open cholecystectomy (OC)on postopera-tive systemic infection and immune response in patients with acute cholecystitis complicated by choleperitonitis.Methods A prospective randomized controlled trial was performed for 45 patients who had a definite diagnosis of acute calculous cholecystitis complicated by cho-leperitonitis in Shanghai Liqun Hospital from January 2014 to June 2016.According to surgical procedures,the patients were randomized in-to LC group (23 patients)and OC group (22 patients).The length of hospital stay,postoperative complications,and deaths were evaluated in both groups.Blood samples were collected from all patients before surgery and at 1,3,and 6 days after surgery to compare the changes in neutrophil count,serum levels of C -reactive protein (CRP)and interleukin -6 (IL -6),and erythrocyte sedimentation rate (ESR),as well as the incidence of endotoxemia.The t -test was used for comparison of continuous data between groups,and the chi -square test was used for comparison of categorical data between groups.Results The LC group had a significantly shorter length of hospital stay than the OC group (5.4 ±2.7 d vs 10.2 ±3.5 d,t = -5.46,P <0.001).One patient (4.3%)in the LC group and 6 (27.3%)in the OC group ex-perienced peritoneal abscess after surgery,and there was a significant difference in the incidence rate of complications between the two groups (χ2 =4.77,P =0.03).In all patients,the mortality rate was 17.8% (8 /45),with 1 (4.3%)in the LC group and 7 (31.8%)in the OC group,and there was a significant difference between the two groups (χ2 =5.16,P =0.02).Of all patients in the OC group,4 died of peritoneal abscess,1 died of pulmonary embolism,and 1 died of myocardial infarction;of all patients in the LC group,1 died of my-ocardial infarction.There were no significant differences in inflammatory markers before surgery between the two groups.At 1,3,and 6 days after surgery,the LC group had significantly lower neutrophil count,serum levels of CRP and IL -6,and ESR (except at 1 day after surger-y)than the OC group (all P <0.05).Furthermore,the OC group had a significantly higher concentration of endotoxin than the LC group (P <0.05),but the level of endotoxin returned to normal at 2 days after surgery in both groups.Conclusion Compared with OC,LC can reduce the probability of endotoxemia,help with the establishment of immunological defense,and reduce the risk of postoperative infection.
