The anatomical, vascular, and immunoregulatory characteristics of the omentum make it an excellent local substrate for the management of radiation soft-tissue injury, infection, and extensive wound defects. This study describes the authors\u2019 experience in complex wound reconstruction using pedicled omental flaps to cover defects in surgery for mobile spine and sacral primary tumors.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>A retrospective cohort analysis was conducted on 34 patients who underwent pedicled omental flap reconstruction after en bloc resection of primary sacral and mobile spine tumors between 2010 and 2020. The study focused on assessing the indications for omental flap usage, including soft-tissue coverage, protection against postoperative radiation therapy, infection management, vascular supply for bone grafts, and dural defect and CSF leak repair. Patient demographic characteristics, tumor characteristics, surgical outcomes, and follow-up data were analyzed to determine the procedure\u2019s efficacy and complication rates.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>From 2010 to 2020, 34 patients underwent pedicled omental flap reconstruction after en bloc resection of sacral (24 of 34 [71%]) and mobile spine (10 of 34 [29%]) primary tumors, mostly chordomas. The patient cohort included 21 men and 13 women with a median (range) age of 60 (32\u201389) years. The most common indication for omental flap was soft-tissue coverage (20 of 34 [59%]). Other indications included protecting abdominopelvic organs for postoperative radiation therapy (6 of 34 [18%]), treating infections (5 of 34 [15%]), providing vascular supply for free fibular bone graft (1 of 34 [3%]), and repairing large dural defects and CSF leak (2 of 34 [6%]). The median (range) follow-up was 24 (0\u2013132) months, during which 71% (24 of 34) of patients did not require additional surgery for wound-related complications. At last follow-up, 59% (20 of 34) had stable disease and 32% (11 of 34) had recurrence, had progression of disease, or had been discharged to hospice after treatment.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>The pedicled omentum is an effective local tissue graft that can be used for complex wound reconstruction and management of high-risk closures in primary spine tumors. This technique may have a lower rate of complications than other approaches and may influence surgical planning and flap selection in challenging cases.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2024.2.spine231134","type":"journal-article","created":{"date-parts":[[2024,5,25]],"date-time":"2024-05-25T01:44:17Z","timestamp":1716601457000},"page":"283-291","source":"Crossref","is-referenced-by-count":5,"title":["Pedicled omental flaps for complex wound reconstruction following surgery for primary spine tumors of the mobile spine and sacrum"],"prefix":"10.3171","volume":"41","author":[{"given":"Elie","family":"Massaad","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shalin S.","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Oncology, MD Anderson Cancer Center, Houston, Texas;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret","family":"Sten","sequence":"additional","affiliation":[{"name":"Interdisciplinary Program in Neuroscience, Georgetown University, Washington, DC; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane","family":"Shim","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Kiapour","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John T.","family":"Mullen","sequence":"additional","affiliation":[{"name":"Surgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel G.","family":"Tobert","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shannon","family":"MacDonald","sequence":"additional","affiliation":[{"name":"Radiation Oncology, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis J.","family":"Hornicek","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Sarcoma Biology Laboratory, Sylvester Comprehensive Cancer Center, and The University of Miami Miller School of Medicine, Miami, Florida"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John H.","family":"Shin","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"24","key":"b1","series-title":"Spine (Phila Pa 1976)","first-page":"2700","article-title":"The surgical management of sacral chordomas","volume":"34","author":"Schwab JH","year":"2009","unstructured":"Schwab JH, Healey JH, Rose P, Casas-Ganem J, Boland PJ.
