Relationships between pelvic nerves and levator ani muscle for posterior sacrocolpopexy: an anatomic study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe placement of posterior mesh during pelvic organ prolapse laparoscopic surgery has been incriminated as responsible for postoperative adverse outcomes such as digestive symptoms, chronic pelvic pain, and sexual dysfunction. These complications may be related to neural injuries that occur during the fixation of the posterior mesh on the levator ani muscle.
objectivesThe aim of our study was to describe the course of the autonomic nerves of the pararectal space and their anatomical relationship with the posterior mesh fixation zone on the levator ani muscle. STUDY
designTwenty hemi-pelvis specimens from 10 fresh female cadavers were dissected. We measured the distance between the posterior mesh fixation zone on the levator ani, and the nearest point of adjacent structures: the hypogastric nerve, inferior hypogastric plexus, uterosacral ligament, uterine artery, and ureter. Measurements were repeated starting from the inferior hypogastric plexus.
resultsNerve fibers of the inferior hypogastric plexus spread out systematically above the superior aspect of the levator ani muscle. Median distance from the posterior mesh fixation zone and the inferior hypogastric plexus was around 2.8 (range 2.1-3.5) cm.
conclusionsThe inferior hypogastric plexus lies above the superior aspect of the levator ani muscle. A short distance between the posterior mesh fixation zone on the levator ani muscle and inferior hypogastric plexus could explain in part postoperative digestive symptoms. These observations support the development of nerve-sparing procedures for posterior mesh placement in the context of pelvic organ prolapse repair and suggest that postoperative complications could be improved by changing the fixation zone.
