To explore the clinical efficacy of single-port laparoscopic appendectomy without robotic arms (SSLA) for recurrent appendicitis, and analyze the factors affecting operative duration.

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.

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).

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.
