The LANN technique to reduce postoperative functional morbidity in laparoscopic radical pelvic surgery

BACKGROUND: We investigated the feasibility and advantages of introducing Laparoscopic Neuro-Navigation (LANN) into the field of laparoscopic gynecologic radical pelvic surgery. STUDY DESIGN: In a prospective pilot study, 261 consecutive patients underwent laparoscopic radical pelvic surgery for cervical cancer or deep infiltrating endometriosis of the parametria. During the procedure, dissection and electrostimulation, and consequently, sparing of the pelvic parasympathetic nerves by transection of the parametria, were performed. Postoperative bladder dysfunction was documented. RESULTS: Laparoscopic dissection and electrostimulation of the pelvic splanchnic nerves were feasible in all pat…
