Abstract:
A modified technique for laparoscopic appendectomy is described. The telescope features two channels, one for the optical system and the second for forceps, scissors, and endoloops. The operation is performed through the working channel. The coaxial instrument is inserted through the umbilicus. One or two additional 1.7-mm instruments stabilize the appendix during the procedure. This technique leaves practically no scars.
