Objective To explore the clinical value of laparoscopic appendectomy with mesoappendix preservation.Methods A retrospective study was conducted,including 1202 patients who underwent laparoscopic appendectomy in our department from January 2019 to December 2023.The patients were divided into a mesoappendix-preserving group(n=697)and a traditional procedure group(n=505)based on surgical technique.The operation time,intraoperative blood loss,postoperative inflammatory markers[white blood cell(WBC)counts on postoperative day 1 and 3,and C-reactive protein(CRP)on postoperative day 3],gastrointestinal recovery time(time to first flatus),postoperative hospital stay,and surgical site infection rates were compared between the two groups.Results The mesoappendix-preserving group had less blood loss than the traditional procedure group[(8.7±3.9)ml vs.(10.1±3.0)ml,t=7.070,P=0.000],shorter operation duration[(78.0±36.0)min vs.(84.0±48.0)min,t=2.032,P=0.042],earlier first exhaust time[(9.0±1.7)h vs.(9.2±1.1)h,t=2.500,P=0.013],and lower surgical site infection rate[1.1%(8/697)vs.3.4%(17/505),χ2=7.077,P=0.008].The mesoappendix-preserving group had lower WBC count on postoperative day 1[(11.2±1.6)×109/L vs.(12.2±2.5)×109/L,t=8.441,P=0.000]and on postoperative day 3[(8.4±2.6)×109/L vs.(9.7±1.3)×109/L,t=11.214,P=0.000],and CRP level on postoperative day 3[(10.7±2.9)mg/L vs.(12.0±5.5)mg/L,t=5.361,P=0.000],with differences statistically significant.Conclusion The mesoappendix-preserving technique optimizes the surgical anatomical approach,reduces intraoperative trauma,mitigates inflammatory stress response,accelerates postoperative gastrointestinal recovery,and lowers surgical site infection rates.
