We present a modified external oblique intercostal block for complete lateral abdominal analgesia with a single injection. Case:  We performed a modified version of the external oblique intercostal block unilaterally at the tenth rib along the mid-axillary line in three patients undergoing robot-assisted partial nephrectomy (two single injections, one catheter placement) and tested the technique on a cadaver with 20 ml of dye bilaterally.  All patients reported good postoperative pain relief without complications and had consistent sensory coverage of the T8\u2013T12 dermatomes from the anterior-to-posterior axillary line.  Anatomical assessment confirmed consistent bilateral staining of the lateral cutaneous branches T8\u2013T12.  Conclusions:  The initial clinical success and anatomical findings of the modified approach to the external oblique intercostal block suggest that this technique may be an effective option for lateral abdominal analgesia.<\/jats:p>","DOI":"10.4097\/kja.24832","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T07:56:02Z","timestamp":1737359762000},"page":"171-176","update-policy":"https:\/\/doi.org\/10.4097\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Modified approach to external oblique intercostal block: a proof-of-concept pilot case series and anatomical evaluation -a case series-"],"prefix":"10.4097","volume":"78","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7105-6296","authenticated-orcid":true,"given":"Takashi","family":"Fujino","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6590-7912","authenticated-orcid":true,"given":"Koichiro","family":"Ichimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4170-5595","authenticated-orcid":true,"given":"Hidaka","family":"Anetai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5791-2700","authenticated-orcid":true,"given":"Izumi","family":"Kawagoe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2573","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000031168"},{"key":"ref2","first-page":"133","volume-title":"Essentials of Our Current Understanding: Abdominal Wall Blocks","author":"Chin","year":"2017"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097\/aap.0000000000000838"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1093\/pm\/pnab296"},{"key":"ref5","first-page":"165","volume-title":"Serratus intercostal interfascial plane block in supraumbilical surgery: a prospective randomized comparison","author":"Fern\u00c1ndez","year":"2021"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-022-02310-4"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-022-02309-x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinane.2022.110953"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.bja.2022.02.011"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinane.2018.10.015"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-023-02485-4"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000030435"}],"container-title":["Korean Journal of Anesthesiology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/ekja.org\/upload\/pdf\/kja-24832.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekja.org\/journal\/view.php?doi=10.4097\/kja.24832","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ekja.org\/upload\/pdf\/kja-24832.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T07:44:21Z","timestamp":1743407061000},"score":1,"resource":{"primary":{"URL":"http:\/\/ekja.org\/journal\/view.php?doi=10.4097\/kja.24832"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,1]]},"references-count":12,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025,4]]}},"URL":"https:\/\/doi.org\/10.4097\/kja.24832","relation":{},"ISSN":["2005-6419","2005-7563"],"issn-type":[{"value":"2005-6419","type":"print"},{"value":"2005-7563","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,1]]},"assertion":[{"value":"2024-11-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-01-10","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-01-20","order":2,"name":"published","label":"Published online","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-01","order":3,"name":"published","label":"Print publication","group":{"name":"publication_history","label":"Publication History"}}]}}
