Stenosis of the pharynx\/oesophagus and stoma shrinkage within five years after surgery were each seen in 18.2% of cases. In 66.7% of cases, conservative treatment of the fistulas was chosen. Rehospitalisations within five years occurred for 44.8% with a median rate of 1.5 (range 1\u201311). Smoking status (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.005 and 0.013) and chronic obstructive pulmonary disease (<jats:styled-content style=\"fixed-case\">COPD<\/jats:styled-content>) (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.013 and 0.011) were significant risk factors for both overall postoperative complications and fistula formation in uni\u2010 and multivariate analysis. Tumour localisation in the hypopharynx was associated with overall postoperative complications (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.036). Residual tumour or cancer recurrence was associated with late\u2010onset fistulas (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The frequencies of postoperative complications after total laryngectomy were comparable with similar international studies, although fistula formation rate is increasing in Denmark. We suggest optimising treatment of <jats:styled-content style=\"fixed-case\">COPD<\/jats:styled-content> and to further encourage to smoking cessation. We propose that development of fistulas &gt;2\u00a0months after surgery prompts immediate biopsies. Additionally, we suggest standardised registration of surgical techniques to identify variables affecting the frequency of postoperative complications.<\/jats:p><\/jats:sec>","DOI":"10.1111\/coa.12443","type":"journal-article","created":{"date-parts":[[2015,4,17]],"date-time":"2015-04-17T15:02:49Z","timestamp":1429282969000},"page":"662-671","source":"Crossref","is-referenced-by-count":25,"title":["Risk factors for postoperative complications after total laryngectomy following radiotherapy or chemoradiation: a 10\u2010year retrospective longitudinal study in Eastern Denmark"],"prefix":"10.1111","volume":"40","author":[{"given":"N.B.","family":"Wulff","sequence":"first","affiliation":[{"name":"Department of Otolaryngology Head &amp; Neck Surgery and Audiology, Rigshospitalet University Hospital of Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.A.","family":"Kristensen","sequence":"additional","affiliation":[{"name":"Department of Oncology Rigshospitalet University Hospital of Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Andersen","sequence":"additional","affiliation":[{"name":"Department of Oncology Herlev Hospital University Hospital of Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Charabi","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head &amp; Neck Surgery and Audiology, Rigshospitalet University Hospital of Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.H.","family":"S\u00f8rensen","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head &amp; Neck Surgery and Audiology, Rigshospitalet University Hospital of Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Hom\u00f8e","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head &amp; Neck Surgery and Audiology, Rigshospitalet University Hospital of Copenhagen Denmark"},{"name":"Department of Otorhinolaryngology and Maxillofacial Surgery K\u00f8ge University Hospital Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,11,18]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"845","article-title":"Long\u2010term results of RTOG 91\u201011: a comparison of three nonsurgical treatment strategies to preserve the larynx in patients with locally advanced larynx cancer","volume":"31","author":"Forastiere A.A.","year":"2013","journal-title":"J.
