Objective:To explore the clinical efficacy of single-port laparoscopic appendectomy without robotic arms (SSLA) for recurrent appendicitis, and analyze the factors affecting operative duration.Methods:A total of 120 patients diagnosed with recurrent appendicitis who underwent surgical treatment in our hospital from January 2023 to December 2025 were enrolled. They were divided into the conventional single-incision laparoscopic surgery (SILS) group (n=65) and the SSLA group (n=55) according to different surgical approaches. SPSS 26.0 software was used for statistical analysis. The intraoperative and postoperative efficacy indicators between the two groups were compared using the t test or χ2 test. Multivariate Logistic regression analysis was performed to identify the factors influencing the operative duration of SSLA.Results:The operative duration in the SSLA group was significantly longer than that in the conventional SILS group (P<0.05). There were no statistically significant differences between the two groups in intraoperative blood loss, time to first postoperative flatus, white blood cell count and C-reactive protein (CRP) level at 48 hours after operation (P>0.05). No significant difference was found in the overall incidence of postoperative complications between the two groups (P>0.05).In the SSLA group, 28 patients with operative duration over 60 minutes were assigned to the >60 min subgroup, and the remaining 27 patients were assigned to the ≤60 min subgroup. The proportions of patients with maximum appendiceal diameter >10 mm and disease course >3 days in the current episode were higher in the >60 min subgroup (P<0.05), and the preoperative CRP level was also significantly elevated in this subgroup (P<0.05). Multivariate Logistic regression analysis indicated that disease course >3 days in the current episode and elevated preoperative CRP level were independent risk factors for prolonged operative duration of SSLA (P<0.05).Conclusion:SSLA is safe and feasible for the treatment of recurrent appendicitis, though it requires longer operative time than conventional SILS. A disease course longer than 3 days and high preoperative CRP level are independent risk factors for prolonged operative duration.
