Laparoscopic neuromapping in pelvic surgery: scopes of application.
2013
Background. New developments in intraoperative electrophysiological neuromonitoring for conventional surgery are providing further insights into functional neuroanatomy and nerve-sparing in the minor pelvis. The aim of this study was to open up potential scopes of application in laparoscopy. Methods. Ten patients with different indications for surgery (presacral tumor excision, n = 2; resection rectopexy. n = 2; low anterior rectal resection, n = 2; proctocolectomy. n = 2; abdomino-perineal excision of the rectum, n = 2) were investigated prospectively. The pelvic autonomic nerves were bilaterally mapped by laparoscopic electric stimulation under simultaneous electromyography of the intern…
Surgical Neuropelveology: Lateral Femoral Cutaneous Nerve Endometriosis. Laparoscopic Resection and Nerve Transplantation
2021
ABSTRACT Study Objective To demonstrate the application of surgical neuroanatomic principles for the diagnosis and treatment of deep infiltrating endometriosis involving the lateral femoral cutaneous nerve. Design Video demonstration of laparoscopic lateral femoral cutaneous endometriosis resection with nerve transplant. Setting Endometriosis infiltrating somatic nerves is a poorly known condition, which can cause severe neuropathic symptoms [1] and is often unrecognized with a subsequent treatment delay [1] . Intimate knowledge of pelvic neuroanatomy and expertise in minimally invasive surgery are essential to manage this challenging surgical scenario 2 , 3 , 4 . Interventions Thirty-six y…
Surface Electromyography Reliably Records Electrophysiologically Evoked Internal Anal Sphincter Activity: A More Minimally Invasive Approach for Moni…
2016
<b><i>Background:</i></b> Even in the case of minimally invasive pelvic surgery, sparing of the autonomic nerve supply is a prerequisite for maintaining anal sphincter function. Internal anal sphincter (IAS) innervation could be electrophysiologically identified based on processed electromyographic (EMG) recordings with conventional bipolar needle electrodes (NE). This experimental study aimed for the development of a minimally invasive approach via intra-anal surface EMG for recordings of evoked IAS activity. <b><i>Methods:</i></b> Six male pigs underwent nerve-sparing low anterior rectal resection. Electric autonomic nerve stimulations were …
The LANN technique to reduce postoperative functional morbidity in laparoscopic radical pelvic surgery
2005
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…
Laparoscopic neurolysis of the sacral plexus and the sciatic nerve for extensive endometriosis of the pelvic wall
2007
Background: The aim of this study is to report on the feasibility of laparoscopic neurolysis of the plexus sacralis and the sciatic nerve in deep endometriotic infiltration of the lateral pelvic wall. Methods: A transperitoneal approach to the pelvic nerves combined with the LANN technique for intraoperative assessment of the function of the exposed nerves permit exposure and sparing of all somatic nerves during resection of the endometriotic lesion. Results: We report on our short experience with 21 patients who underwent this technique for the treatment of endometriotic infiltration of the sacral plexus at different levels. Conclusion: In young patients with chronic unilateral sciatica or…
