Intramural esophageal hematoma has been described as a rare complication of sclerotherapy. Risk factors have not been completely established. OBJECTIVE: To demonstrate the incidence of post-sclerotherapy intramural esophageal hematoma in our hospital and discuss the possible factors involved. Methods - This is a retrospective observational study made at the \"Hospital Universit\u00e1rio Clementino Fraga Filho\", Rio de Janeiro, RJ, Brazil, reviewing the medical records of all esophageal variceal sclerotherapy procedures performed from April 2000 to November 2005. The evaluation of the clinical, laboratorial and endoscopic features in our patients and those reported in the literature was also done. Review of literature was performed through MEDLINE search. RESULTS: A total of 1,433 esophageal variceal sclerotherapy procedures were performed in 397 patients, with an intramural esophageal hematoma incidence of 4 cases (0.28%). Three of our patients developed additional complications, and one death was a direct consequence of a rupture of the hematoma. Nineteen well described cases were reported in the literature. Intramural esophageal hematoma occurred mostly after the forth esophageal variceal sclerotherapy session. Coagulation disturbances were present in the majority of cases. CONCLUSION: Intramural esophageal hematoma is a rare complication of esophageal variceal sclerotherapy and its incidence in our institution was similar to those observed in the literature. Our study suggests that this complication occurs as a result of a fragile esophageal mucosa after previous esophageal variceal sclerotherapy sessions. Impaired coagulation, although not essential, could contribute to hematoma formation and extension through esophageal submucosa.<\/jats:p>","DOI":"10.1590\/s0004-28032009000400006","type":"journal-article","created":{"date-parts":[[2010,3,11]],"date-time":"2010-03-11T13:28:28Z","timestamp":1268314108000},"page":"279-283","source":"Crossref","is-referenced-by-count":2,"title":["Intramural esophageal hematoma after elective injection sclerotherapy"],"prefix":"10.1590","volume":"46","author":[{"given":"Hannah Pitanga","family":"Lukashok","sequence":"first","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil; Edouard Herriot Hospital,  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Robles-Medranda","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil; Edouard Herriot Hospital,  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00edlia de Andrade","family":"Santana","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcia Henriques Magalh\u00e3es","family":"Costa","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana de Almeida","family":"Borges","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cyrla","family":"Zaltmani","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"466","article-title":"Endoscopic incision for esophageal intramural hematoma after injection sclerotherapy: case report","volume":"58","author":"Adachi T","year":"2003","journal-title":"Gastrointest Endosc","ISSN":"http:\/\/id.crossref.org\/issn\/0016-5107","issn-type":"print"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"235","DOI":"10.1055\/s-2007-1004182","article-title":"A prospective randomized trial of sclerotherapy versus ligation in the elective treatment of bleeding esophageal varices.","volume":"29","author":"Baroncini D","year":"1997","journal-title":"Endoscopy","ISSN":"http:\/\/id.crossref.org\/issn\/0013-726X","issn-type":"print"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1111\/j.1443-1661.2004.00299.x","article-title":"Intramural esophageal hematoma after endoscopic injection sclerotherapy for bleeding varices.","volume":"16","author":"Beljon JV","year":"2004","journal-title":"Dig Endosc"},{"key":"ref4","first-page":"478","article-title":"H\u00e9matome intra-mural obstructif de l'oesophage post-scl\u00e9roth\u00e9rapie: Presse Med. 1996;25:1281-4.Boix J, Lorenzo-Z\u00fa\u00f1iga V, Moreno de Vega V, Dom\u00e8nech E, Gassull MA.
