Successful intrathecal neurolytic block for the management of cancer pain in a 10-year-old child: a case report

Background Cancer pain management in children is challenging owing to their unique patient characteristics. We present the case of a 10-year-old girl whose cancer pain was successfully managed using an intrathecal neurolytic block. Case presentation The patient experienced severe cancer pain due to recurrent right ilium osteosarcoma. The tumor progressed rapidly despite chemoradiotherapy and gradually invaded the right lumbar plexus, which resulted in severe neuropathic pain in the right lower extremity. Systemic analgesics failed to attenuate the pain. We performed an intrathecal neurolytic block using 10% phenol-glycerol. The neurolytic block completely relieved her right lower extremity pain. After the block, the patient’s quality of life improved, and she spent her time with family. Conclusions The intrathecal neurolytic block successfully relieved the patient’s cancer pain. Successful intrathecal neurolytic blocks require meticulous pain assessment of individual patients, to avoid possible serious complications such as paresis/paralysis and bladder/bowel dysfunction.

Effectiveness of the superior hypogastric plexus neurolytic block in the management of pelvic abdominal pain in adult patients diagnosed with cancer: A systematic literature review

Introduction: Severe oncological pain occurs in up to 60% of pelvic abdominal cáncer patients, being refractory to medical management in up to 30% of cases. In 1990, the superior hypogastric plexus neurolytic block (SHPB) was described for the control of pain in these patients. This study aimed to evaluate the effectiveness of this technique for the control of oncological pain. Methodology: Studies that evaluated the effectiveness of the SHPB using the classic or transdiscal approach in adult patients with oncological abdominal-pelvic pain were systematically reviewed. A search was conducted in PubMed, EMBASE and Scopus from January 1, 1990, to August 31, 2019, without a language restriction. The visual analog scale (VAS), morphine milligram equivalents (MME) per day, quality of life and presence of complications were recorded. The quality of the studies was evaluated using the Jadad and Ottawa-Newcastle scales. Results: Eight studies met the inclusión criteria: 6 were descriptivo longitudinal studies, and 2 were controlled clinical trials, comprising 316 patients (75% female and 25% male; average age 53.2 years); the most frequent diagnoses were gynecological (65%) cancer. An average VAS reduction of 55%-60.8% was obtained as well as a MME reduction of 40%-60%. Three studies evaluated the quality of life using the (QLQ-C30), (PSS) and Zubrod scale all with positive results. Complications were reported in 18% of cases, pain related to the puncture was the most frequent. Conclusions: The SHPB may be an effective for the control of severe oncological abdominal-pelvic pain, decreasing the VAS and MME and improving the quality of life of patients.

Celiac Plexus Blockade and Neurolysis: Ultrasound

There has been a growing interest in ultrasound-guided celiac plexus blocks, especially neurolytic blocks, for terminally ill patients with upper abdominal malignancies. These patients are usually frail and difficult to transfer to the radiology suite. Ultrasound-guided celiac plexus neurolytic block can be performed at the bedside with appropriate monitoring. This chapter focuses on ultrasound guidance. It reviews the advantages of ultrasound compared with other imaging modalities in celiac plexus block as well as the step-by-step technique and how to avoid complications.

Superior Hypogastric Plexus Combined with Ganglion Impar Neurolytic Blocks for Pelvic and/or Perineal Cancer Pain Relief

Background: The superior hypogastric plexus (SHGP) carries afferents from the viscera of the lower abdomen and pelvis. Neurolytic block of this plexus is used for reducing pain resulting from malignancy in these organs. The ganglion impar (GI) innervats the perineum, distal rectum, anus, distal urethra, vulva, and distal third of the vagina. Different approaches to the ganglion impar neurolysis have been described in the literature. Objectives: To assess the feasibility, safety, and efficacy of combining the block of the SHGP through the postero-median transdiscal approach with the GI block by the transsacro-coccygeal approach for relief of pelvic and/or perineal pain caused by pelvic and/or perineal malignancies or any cancer related causes. Methods: Fifteen patients who had cancer-related pelvic pain, perineal pain, or both received a combined SHGP neurolytic block through the postero-median transdiscal approach using a 20-gauge Chiba needle and injection of 10 mL of 10% phenol in saline plus a GI neurolytic block by the trans-sacro-coccygeal approach using a 22-gauge 5 cm needle and injection of 4 – 6 mL of 8% phenol in saline. Pain intensity (measured using a visual analogue scale) and oral morphine consumption pre- and post-procedure were measured. Results: All patients presented with cancer-related pelvic, perineal, or pelviperineal pain. Pain scores were reduced from a mean (± SD) of 7.87 ± 1.19 pre-procedurally to 2.40 ± 2.10 one week post-procedurally (P < 0.05). In addition, the mean consumption of morphine (delivered via 30 mg sustained-release morphine tablets) was reduced from 98.00 ± 34.89 mg to 32.00 ± 28.48 mg after one week (P < 0.05). No complications or serious side effects were encountered during or after the block. Limitations: This study is limited by its small sample size and non-randomized study. Conclusion: A combined neurolytic SHGP block with GI block is an effective and safe technique for reducing pain in cancer patients presented with pelvic and/or perineal pain. Also, a combined SHGP block through a posteromedian transdiscal approach with a GI block through a trans-sacrococcygeal approach may be considered more effective and easier to perform than the recently invented bilateral inferior hypogastric plexus neurolysis through a transsacral approach. Key words: Superior hypogastric plexus block, ganglion impar block, cancer pain, pelvic pain, perineal pain

Celiac Plexus Neurolysis Using Three Different Techniques for Upper Abdominal Metastatic Pain: Comparison the Effectiveness of the Block

33 patients [13 female] with metastatic intractable upper Abdominal Cancer Pain were treated with celiac plexus neurolytic block with 60% alcohol. Aim of study is to observe the effectiveness of three different techniques of celiac plexus block, unilateral paravertibral, bilateral paravertibral and Paravertibral transaortic approach of celiac plexus blocks under C- arm guidance. Satisfactory pain relief occurs in all three techniques but out- come of transaortic approach a little better than other methods. Pain intensity was assessed by VRS and VAS Scale. Celiac plexus blocks are a suitable technique for upper abdominal visceral metastatic pain. Its effects are prolonged and also increase bowel movement, improve appetite and reduced morphine consumption. This is an initial study and numbers of subject are few. So more study required to get conclusive result. Skilled manpower and appropriate case selection is mandatory for successful results.
