Intrapelvic Nerve Entrapment Syndrome Caused by a Variation of the Intrapelvic Piriformis Muscle and Abnormal Varicose Vessels: A Case Report / 대한배뇨장애요실금학회지

Entrapment neuropathy of the sciatic nerve and pudendal nerve are painful syndromes that are often overlooked by physicians. Laparoscopic surgical interventions for nerve entrapment syndromes of the posterior pelvis focus on removing the compression lesion with the purpose of eliminating the suspected cause of sciatica, as well as pudendal neuralgia. Herein, the authors report the rare event of sciatic and pudendal nerve entrapment, which was caused by aberrant vessels and a variant piriformis muscle bundle, as a seldom-diagnosed cause of sciatica and pelvic pain, for both neurosurgeons and neuropelveologists. The authors present the laparoscopic decompression technique for the pudendal and sciatic nerves by giving our technical “tips and tricks” enriched by a surgical video.

Robot-assisted laparoscopic management of a vascular entrapment of the sacral nerve roots causing pelvic pain.

The aim of this case report is to demonstrate the robot-assisted laparoscopic decompression approach to treat the aberrant vessels entrapping the sacral nerves causing pelvic pain. A 34-year-old female patient had been complaining about pelvic pain on the left perineal region which was radiating to the sacral 1-2 nerves dermatome for 3 years. Decompression of sacral nerve roots and sciatic nerve was performed via robot-assisted and a four-arm Da Vinci Si Surgical System laparoscopic approach. This case report is the first presentation of robot-assisted laparoscopic management of a vascular entrapment of the sacral nerve roots. The robotic technique offers, three-dimensional vision, improved maneuverability and enhanced ergonomics in the deepest area in the pelvis and could be a valid alternative to laparoscopy in the treatment of intrapelvic neurovascular entrapments.

Comparison of Ultrasound-Guided Transgluteal and Finger-Guided Transvaginal Pudendal Nerve Block Techniques: Which One is More Effective? / 대한배뇨장애요실금학회지

PURPOSE: Pudendal neuralgia (PN) is a painful and disabling condition, which reduces the quality of life as well. Pudendal nerve infiltrations are essential for the diagnosis and the management of PN. The purpose of this study was to compare the effectiveness of finger-guided transvaginal pudendal nerve infiltration (TV-PNI) technique and the ultrasound-guided transgluteal pudendal nerve infiltration (TG-PNI) technique.METHODS: Forty patients who underwent PNI for the diagnosis of PN were evaluated. Thirty-five of these 40 patients, who were diagnosed as PN, underwent a total of 70 further unilateral PNI. All the patients underwent PNI for twice after the first diagnostic PNI, 1 week apart.RESULTS: In the ultrasound (US)-guided TG-PNI group, the success rate was 68.8% (11 of 16) in both “pain in the sitting position” and “pain in the region from the anus to the clitoris.” The success rate of blocks in the US-guided TG-PNI group was 75% (12 of 16) in terms of pain during/after intercourse. In the finger-guided TV-PNI group, the success rate was 84.2% in both “pain in the sitting position” and “pain in the region from the anus to the clitoris.” The success rate of blocks in the fingerguided TV-PNI group was 89.5% (17 of 19) in terms of pain during/after intercourse. There was no statistically significant difference in the success rate of the 3 assessed conditions between the 2 groups (P>0.05).CONCLUSIONS: The TV-PNI may be an alternative to US-guidance technique as a safe, simple, effective approach in pudendal nerve blocks.
