Abstract: Objective:To explore the feasibility and safety of laparoscopic appendectomy for root gangrenous perforative appendicitis.Methods:Retrospective study clinical data of 163 patients with root gangrenous perforative appendicitis，who received surgical treatment（78 cases of laparoscopic operation and 85 cases of laparotomy），contrastive analysis of operation time，hospital stay and postoperative complications.Results:All patients were cured by the successful resection of appendix，all healed.There were significant differences in operation time，hospitalization time and incision infection between the two groups（P<0.05）.Laparoscopic surgery had advantages.There was no significant difference in the incidence of abdominal abscess and stump fistula between the two groups（P>0.05）.Conclusion:Laparoscopic surgery for the treatment of root gangrenous performative appendicitis is safe and feasible.
