A novel three-port trocar placement technique for laparoscopic radical prostatectomy

摘要

Images of the external cavity. a With an assistant holding the laparoscope, the surgeon alone completed all procedures of the operation. b Only three trocars were placed, including one just in the umbilical region and two on the left/right lateral margin of the rectus abdominis muscle with a length of 2 finger-breadths below the umbilicus. c The total lengths of incisions were 1.5 + 0.5 + 0.5 = 2.5 cm for the prostate volume (evaluated by preoperative B-ultrasonography) ≤ 30 ml or 2.5 + 0.5 + 0.5 = 3.5 cm for the prostate volume > 30 ml
