BACKGROUND: Long-term morbidity after multimodal treatment for rectal cancer is suggested to be mainly made up by nerve-injury-related dysfunctions. Stereotactic navigation for rectal surgery was shown to be feasible and will be facilitated by highlighting structures at risk of iatrogenic damage. The aim of this study was to investigate the ability to make a 3D map of the pelvic nerves with magnetic resonance imaging (MRI). METHODS: A systematic review was performed to identify a main positional reference for each pelvic nerve and plexus...

Endovascular repair of iliac artery aneurysms has emerged as an alternative to traditional open surgical repair. Although there is little consensus on indications to preserve hypogastric blood flow during aneurysm repair, it is well understood that complications from bilateral hypogastric occlusion may be significant. The GORE EXCLUDER Iliac Branch Endoprosthesis (W. L. Gore and Associates, Flagstaff, Ariz) received United States Food and Drug Administration approval in March 2016 for treatment of common iliac artery and aortoiliac aneurysms...

The inputs from sympathetic ganglia have been known to be involved in the pathophysiology of various painful conditions such as complex regional pain syndrome, cancer pain of different origin, and coccygodynia. Sympathetic ganglia blocks are used to relieve patients who suffer from these conditions for over a century. Many numbers of local anesthetics such as bupivacaine or neurolytic agents such as alcohol can be chosen for a successful block. The agent is selected according to its duration of effect and the purpose of the injection...

A retrospective study was performed to examine the efficacy of intraoperative monitoring of the external anal sphincter (EAS) muscle-evoked potential after a transcranial muscle-action potential (Tc-MsEP) in spinal cord surgery, and to evaluate alarm points for EAS waveform deterioration related to postoperative bowel bladder disorder (BBD). BBD is caused by damage to the hypogastric, pelvic, and pudendal nerves and leads to a significant reduction in quality of life. Intraoperative Tc-MsEP monitoring using the EAS is common to prevent neurological deficit, but the relationship of BBD with intraoperative monitoring of the EAS has not been examined...

Bladder exstrophy is a malformation characterized by subumbilical anterior abdominal wall and anterior bladder wall deishence. It affects nearly 30.000-40.000 births per year, with a higher prevalence in boys. External continent urinary diversion creates a long-term outcome. However, it is not devoid of complications. We report the case of a 30-year old female patient who had undergone cystectomy with bladder replaced with ileo-caecal segment for bladder exstrophy 13 years earlier. She was followed up for 5 years and then lost to follow up...

Bladder dysfunction remains a major postoperative challenge for early stage cervical cancer patients. The present prospective phase 2 trial in patients with stage IB1 and IIA1 cervical cancer follows up on our previous, unpublished work describing a new surgical landmark, the paravesico-vaginal space. We describe a novel nerve-sparing radical hysterectomy (NSRH) approach to treat early stage cervical cancer without compromising local control rate or survival. Between September 2015 and August 2016, 49 patients were enrolled to receive NSRH...

Injury to the nerves of the aortic- and superior hypogastric plexuses during retroperitoneal surgery often results in significant post-operative complications, including retrograde ejaculation and/or loss of seminal emission in males. Although previous characterizations of these plexuses have done well to provide a basis for understanding the typical anatomy, additional research into the common variations of these plexuses could further optimize nerve-sparing techniques for retroperitoneal surgery. To achieve this, the present study aimed to document the prevalence and positional variability of the infrarenal lumbar splanchnic nerves (LSNs) through gross dissection of 26 human cadavers...

Being located in the hypogastric area, the ilioinguinal nerve, together with iliohypogastric nerve, can be damaged during lower abdominal surgeries. Conventionally, the diagnosis of ilioinguinal neuropathy relies on clinical assessments, and standardized diagnostic methods have not been established as of yet. We hereby report the case of young man who presented ilioinguinal neuralgia with symptoms of burning pain in the right groin and scrotum shortly after receiving inguinal herniorrhaphy. To raise the diagnostic certainty, we used a real-time ultrasonography (US) to guide a monopolar electromyography needle to the ilioinguinal nerve, and then performed a motor conduction study...

The arterial basket of the conus medullaris is one of several anastomoses between the anterior and posterior spinal arteries. The anatomy of this structure has attracted little attention. This work sought to investigate its configuration in human spinal cords. Spinal cords from male and female cadavers (n = 32) were injected with colored latex through the intercostal, lumbar, medial sacral and the posterior trunks of the hypogastric arteries. After injection, specimens preserving the dural sac were obtained and fixed in formaldehyde solution...
