It was reported via journal article: "title: laparoscopic appendectomy using endoloops".Author(s): g.Beldi, k.Muggli, c.Helbling, r.Schlumpf.Citation: surg endosc (2004) 18: 749¿750; doi: 10.1007/s00464-003-9156-z.This prospective, randomized clinical trial aimed to evaluate the number of loops needed for laparoscopic appendectomy.Between jul1999 and nov2000, 208 patients with suspected appendicitis underwent laparoscopic appendectomy in which 109 had one loop (group 1) and 99 had two loops (group 2).In the procedure, one or two endoloops was placed near to the appendix base and additional endoloop was placed 6-12mm distally.In group 1, complication included intraabdominal abscess (n=5) treated with reoperation (n=1) and percutaneous drainage (n=2).In group 2, complications included abscess (n=4) treated with surgical drainage and percutaneous drainage (n=2) of which one had prolonged drainage through a percutaneous drain for 10 days.A potentially higher rate of stump insufficiency in group 1 due to an insufficient closure of the base of the appendix was not observed.Another reason for septic complications after appendectomy could be an infected hematoma.The significance of insufficient hemostasis that, in combination with a localized bacterial peritonitis, causes abscess formation remains unknown.In conclusion, the present study shows that the treatment of the appendix base can be safely done with the use of only one endoloop.
