Abstract: Objective To study the clinical effect of a self-made single-hole device assisted by abdominal wall puncture suture needle in appendectomy.Methods A retrospective analysis of the clinical data of 80 patients undergoing laparoscopic appendectomy admitted to the Department of General Surgery,Taikang Xianlin Drum Tower Hospital,the Affiliated Hospital of Nanjing University Medical School,from July 2018 to July 2021,36 of them were self-made with abdominal wall puncture needles.Single-port device treatment(puncture needle group),44 cases were treated with traditional three-port laparoscopic treatment(traditional group),the operation time,blood loss,anal exhaust time,hospital stay,pain score and postoperative wound infection were compared between the two groups Situation and other indicators. Results There was no significant difference between the puncture needle group and traditional group of patients in terms of median operative time(35min vs.35min),median blood loss(12.5ml vs.15ml),median anal exhaust time(1 day vs.1 day),median hospital stay(5 days vs.5 days) and postoperative wound infection(0 case vs.2 cases)(P>0.05).The puncture needle group had significantly lower pain scores[3(2,3)] than the traditional[3(2,4)] on the first postoperative day(P<0.05).Conclusion The use of abdominal wall puncture suture needle to assist self-made single-hole device for appendectomy is safe and effective.Postoperative pain is significantly improved,hospitalization time is short,postoperative scars are small,and more beautiful.
