In cases\nof LISCs resistant to conservative treatments, various minimally invasive percutaneous spinal\ntechniques (MIPSTs) may be applied prior to open surgery.\nObjectives: The outcomes of 3-staged MIPSTs for the treatment of symptomatic LISCs resistant\nto conservative treatments were evaluated.\nStudy Design: An institutional review board approved retrospective chart review.\nSetting: University hospital inpatients referred to our pain clinic.\nMethods: Review of charts of all patients who underwent MIPSTs for symptomatic LISCs resistant\nto conservative treatments during a time period of 13 years at a university hospital pain clinic.\nPatients with symptomatic LISCs resistant to conservative treatments were treated with 3-staged\nMIPSTs, including image-guided intraarticular aspiration, cyst distention and rupture, and injection\nof corticosteroids (ARI), endoscopic cyst enucleation (ECE), and endoscopic superior facetectomy\n(ESF) by a single pain specialist. A symptom-free period after each intervention was evaluated.\nRecurrence was defined as the same recurrent symptomatic radicular pain with confirmation of\nthe LISC on magnetic resonance imaging. All patients with a minimum follow-up time of 3 years\nwere included.\nResults: Of the 40 patients who underwent ARI, 3 patients failed to complete a follow-up and\n19 patients (51.4%) who had recurring symptoms received ECE. Ten patients (52.6%) who had rerecurring symptoms after ECE received ESF. There was no recurrence after ESF.\nLimitations: This retrospective and observational study with a limited number of patients does\nnot represent a high level of evidence.\nConclusions: This information provided the recurrence rate after each intervention. Half of the\npatients who went on to receive ARI experienced recurrence, whereas half of the patients with\nrecurrence who received ECE experienced re-recurrence. ESF treatment resulted in no recurrence\nwithin the 3-year study period.\nKey words: Conservative treatment, endoscopic surgical procedures, facet joint, intraarticular\ninjection, minimally invasive surgical procedures, needle biopsy, nerve root compression,\nradiculopathy, synovial cysts<\/jats:p>","DOI":"10.36076\/ppj\/2019.22.e451","type":"journal-article","created":{"date-parts":[[2021,2,19]],"date-time":"2021-02-19T17:18:57Z","timestamp":1613755137000},"page":"E451-E456","source":"Crossref","is-referenced-by-count":12,"title":["A Staged Treatment of Symptomatic Lumbar\nIntraspinal Synovial Cysts"],"prefix":"10.36076","volume":"5","author":[{"suffix":"MD","given":"Kyung-Hoon","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Anesthesia and Pain Medicine, Pain Clinic, Pusan National University Yangsan Hospital, Kyungsangnamdo, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"21814","published-online":{"date-parts":[[2019,9,12]]},"container-title":["Pain Physician"],"original-title":[],"language":"en","deposited":{"date-parts":[[2021,2,19]],"date-time":"2021-02-19T17:18:59Z","timestamp":1613755139000},"score":1,"resource":{"primary":{"URL":"https:\/\/painphysicianjournal.com\/current\/pdf?article=NjUxNA%3D%3D&journal=122"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9,11]]},"references-count":0,"issue-title":["September 2019"],"journal-issue":{"issue":"22;5","published-online":{"date-parts":[[2019,9,6]]},"published-print":{"date-parts":[[2019,9,5]]}},"URL":"https:\/\/doi.org\/10.36076\/ppj\/2019.22.e451","archive":["Internet Archive","Internet Archive"],"relation":{},"ISSN":["2150-1149","1533-3159"],"issn-type":[{"value":"2150-1149","type":"electronic"},{"value":"1533-3159","type":"print"}],"subject":[],"published":{"date-parts":[[2019,9,11]]}}}
