RESUMO

【Objective】 To compare the efficacy of radiofrequency thermocoagulation and pulsed radiofrequency for the ganglion impar in treating primary perineal pain. 【Methods】 We analyzed 79 patients with primary perineal pain who underwent radiofrequency thermocoagulation (group A) and pulsed radiofrequency (group B) in the ganglion impar from January 2020 to March 2022. VAS, excellent and good rates, sleep quality, postoperative medication usage, complications, and recurrence were evaluated before and 24 h, 1 W, 1 M, 3 M and 6 M after operation. The differences between the two groups were compared. 【Results】 The VAS score of group A gradually decreased at each level after operation, and the VAS score of group B gradually increased after 24 hours of operation. The differences between the two groups began to appear 1 week after operation, and the differences further increased with the extension of time (P<0.001). In six months after follow-up, the excellent and good rates of group A (86%) was significantly higher than that of group B (22%). In addition to postoperative perineal skin numbness, group A was superior to group B in improving sleep, postoperative oral medication (pregabalin and opioids), and disease recurrence (P<0.05). 【Conclusion】 Radiofrequency thermocoagulation for the ganglion impar can improve the quality of life by reducing pain, improving the excellent and good rates, improving sleep, and reducing recurrence a medication. The effect is better than that of pulsed radiofrequency.

RESUMO

BACKGROUND: Ganglion impar blockade is a reliable and effective treatment option used in patients with coccydynia. Our primary objective was to specify the role of corticosteroids in impar blockade. We compared applications of local anesthetic with the local anesthetic + corticosteroid combination in terms of treatment efficiency in patients with chronic coccydynia. METHODS: Our study was a prospective randomize double-blind study. The patients were divided into 2 groups after randomization. The first group (group SL) was made up of patients where a corticosteroid + local anesthetic were used during ganglion impar blockade. In the second group (group L) we used only local anesthetic. We evaluated numeric rating scale (NRS) and Beck depression scale, which were employed before the procedure and in 1st and 3rd months after the procedure. RESULTS: Seventy-three patients were included in the final analysis. We detected a significantly greater decrease in NRS values in the 1st month in group SL than in group L (P = 0.001). In the same way, NRS values in the 3rd month were significantly lower in the group with steroids (P = 0.0001). During the evaluation of the Beck test, we detected significantly greater decreases in the 1st month (P = 0.017) and 3rd month (P = 0.021) in the SL group than in the L group. CONCLUSIONS: Ganglion impar blockade decreases pain in the treatment of chronic coccydynia and improve depression. Addition of steroids in a ganglion impar blockade is required for treatment response that should accumulate over a long period of time.

RESUMO

Objective To evaluate the efficacy of triamcinolone acetonide injection by ganglion impar block in treating sacral nerve dysfunction syndrome.Methods Fifty-four cases of sacral nerve disorder syndrome,mainly presented with anal pendant expansion,were admitted between October 2014 to October 2016.The clinical efficacy assessed by visual analogue scale(VAS)was recorded and analyzed.Results For all patients,the symptoms were relieved in 15 minutes after ganglion impair block,and the VAS was significantly reduced after treatment.The excellent rate was 81.5% and the total efficiency was 100.0% in one week after surgery.Meanwhile,the excellent rate and the total efficiency were 90.7% and 100.0% in one month,94.4% and 100.0% in 3 months,83.3% and 100.0 % in 6 months,respectively.Conclusions Triamcinolone acetonide injection by ganglion impar block is effective for sacral nerve dysfunction mainly presented with anal pendant expansion.

RESUMO

Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.

RESUMO

Coccygodynia is a common problem that is characterized by pain in the tailbone that radiates to the lower sacral and perineal areas. Coccygodynia may occur after a fall in the sitting position or damage to the sacrococcygeal ligament during a difficult vaginal delivery.Currently, the therapeutic options for coccygodynia are unclear, however, a number of treatment approaches have been proposed.In this case a favorable outcome was obtained by using a radiofrequency lesion generator to create a lesion on the ganglion impar in a patient with chronic coccygodynia.

RESUMO

The ganglion impar is a solitary retroperitoneal structure at the caudal end of the paravertebral sympathetic chain. Block of this ganglion has been advocated as a means of managing intractable perineal pain. In 1990, Plancarte et al performed a neurolytic block of the ganglion impar using 4-6 ml of 10% phenol through the intergluteal skin over the anococcygeal ligament. However, technical difficulties are encountered with the placement of the needle while performing this technique, with complications from the injection of phenol also being a possibility. In 1995, a modified approach for blocking the ganglion impar through the sacrococcygeal ligament was introduced by Wemm and Saberski. We used a radiofrequency (RF) lesion generator to create a controlled and localized lesion with a lower incidence of neural damages compared to chemical neurolysis. RF thermocoagulation of the ganglion impar through the sacrococcygeal ligament was performed on a 70-year-old male patient with constant anal pain using a curved TEW electrode. The patient has been relieved of his pain, without serious complication. Therefore, this technique may be an easier and safer approach, which is associated with fewer chances of complications.

RESUMO

Ganglion impar block is a known useful method of controlling perineal cancer pain. Moreover, this method may be suitable for hyperhidrosis because the visceral cancer pain signal and sweating are transmitted by the same sympathetic chain. We experienced a patients who had suffered from systemic hyperhidrosis especially in the sacral and buttock area. She also had long-standing diabetes mellitus and chronic renal failure. Her excessive sweating occurred during hemodialysis. We treated this patients using a ganglion impar block and achieved a good result.

RESUMO

The perineum refers to the anatomical area immediately below the pelvis, and is comprised of diverse anatomic and somatic innervation. Although various interventions have been proposed for the management of intractable cancer-related perineal pain, their efficacy are limited because the target of nerve blocks has focused on somatic rather than sympathetic components. Recently, blockade of the ganglion impar has been introduced as an alternative means of managing intractable neoplastic perineal pain of sympathetic origin. We successfully treated a patient who had suffered from cancer-related intractable perineal pain with ganglion impar block.
