Abstract: Objective To explore the incidence and influencing factors of complications after laparoscopic appendectomy for perforated appendicitis. Methods A retrospective analysis was conducted on 150 patients with perforated appendicitis admitted to our hospital from February 2019 to February 2023, 80 patients treated with laparoscopic appendectomy were divided into an observation group, and 70 patients treated with traditional open surgery were divided into a control group. The perioperative related indicators and incidence of complications were compared between the two groups. Divide 19 out of 150 patients with postoperative complications into a complication group, and divide the remaining patients into a non complication group. Analyze the relevant influencing factors of postoperative complications and apply logistic regression analysis to analyze the independent influencing factors of complications. Results There was no significant difference in treatment costs between the two groups of patients (P>0.05). The observation group had significantly higher surgical time than the control group (P<0.05). The observation group had significantly lower postoperative antibiotic use time, hospitalization time, postoperative exhaust time, and first postoperative bed activity time compared to the control group (P<0.05). The incidence of complications in the observation group was 3.75%, while in the control group it was 22.86%. The observation group was significantly lower than the control group (P<0.05). There was no significant difference between the non complication group and the complication group in terms of gender and BMI (P>0.05). There were significant differences between the non complication group and the complication group in terms of age, operation mode, combined diabetes, hospital stay, operation time and preoperative WBC count (P<0.05). The results of logistic regression analysis showed that surgical method, surgical timing, and preoperative WBC count were independent risk factors for postoperative complications of perforated appendicitis (P<0.05). Conclusion Laparoscopic appendectomy can reduce the hospitalization time of patients with perforated appendicitis, promote postoperative recovery, and have a low incidence of complications. And the surgical method, timing, and preoperative WBC count are independent risk factors for postoperative complications of perforated appendicitis.
