Internal anal sphincter nerves - a macroanatomical and microscopic description of the extrinsic autonomic nerve supply of the internal anal sphincter.
2017
Background: The internal anal sphincter (IAS) contributes substantially to anorectal functions. While its autonomic nerve supply has been studied at the microscopic level, little information is available concerning the macroscopic topography of extrinsic nerve fibres. This study was designed to identify neural connections between the pelvic plexus and the IAS, provide a detailed topographical description, and give histological proof of autonomic nerve tissue. Methods: Macroscopic dissection of pelvic autonomic nerves was performed under magnification in seven (5 males, 2 females) hemipelvises obtained from body donors (67-92 years). Candidate structures were investigated by histological and…
The "Laparoscopic Neuro-Navigation" -- LANN: from a functional cartography of the pelvic autonomous neurosystem to a new field of laparoscopic surgery
2006
It is the objective of this study to etablish the technique of laparoscopic exposure of all pelvic somatic and autonomous nerves. In all our patients who underwent a laparoscopic surgical approach of the retroperitoneum, exposure and assessment of the exposed nerves using laparoscopic neuro-navigation were performed. Laparoscopic surgery allows the surgical approach to all pelvic nerves, particularly to the sciatic nerve, the pudendal nerve and the splanchnic pelvic nerves. We describe a cartography of the functional anatomy of the pelvic plexus and elaborate on the concept of "laparoscopic pelvic functional surgery". © 2004 Taylor & Francis.
Die laterale Dissektion des Mesorektums ; ein Risiko für den Plexus hypogastricus inferior
2004
Lateral mesorectal dissection may injure parasympathetic and sympathetic pelvic nerves and a partial or complete lesion of the autonomic pelvic nerves leads to urogenital dysfunctions affecting patient’s quality of life after rectum resection for rectal carcinoma. The aim of the present prospective study was to clarify the significance for nerve damage during lateral dissection based on standardized assessment parameters. 15 Patients underwent total mesorectal excision for rectal carcinoma (UICC I/II/III/IV: 1/5/3/6). Within the scope of the stanardized intraoperative data collection it was demonstrated, whether a complete preservation of the autonomie pelvic nerves was successful. In 11 pa…
