There are few publications on appendectomy\u2010related mortality. Removal of a normal appendix has been suggested to be related to a higher mortality rate versus removal of an inflamed appendix.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data on all appendectomy patients between 1990 and 2010\u00a0in Finland were retrieved from the Discharge Register of the National Institute for Health and Welfare and combined with data from the Death Certificate Register of Statistics Finland. Thirty\u2010day mortality was identified and compared with overall mortality. Detailed information from death certificates of patients dying within 30\u2010day post\u2010surgery was collected and analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Over the study period, the thirty\u2010day post\u2010appendectomy mortality rate was 2.1\/1000. Increased mortality was found in patients over 60 years of age. Negative appendectomy and complicated appendicitis were related to mortality. The negative appendectomy rate was higher in patients older than 40 years of age. During the study period, both mortality and the rate of negative appendectomies decreased, while the rate of laparoscopic appendectomies increased.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Post\u2010appendectomy mortality is related to both negative appendectomies and complicated appendicitis. Diagnostic accuracy is fundamental in the care of patients with acute appendicitis, especially in the elderly. Improved diagnostic accuracy may have reduced mortality over the last two decades in Finland.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-016-3688-6","type":"journal-article","created":{"date-parts":[[2016,8,17]],"date-time":"2016-08-17T15:50:10Z","timestamp":1471449010000},"page":"64-69","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Mortality Related to Appendectomy; a Population Based Analysis over Two Decades in Finland"],"prefix":"10.1002","volume":"41","author":[{"given":"Sannamari","family":"Kotaluoto","sequence":"first","affiliation":[{"name":"Department of Gastroenterology and Alimentary Tract Surgery Tampere University Hospital Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mika","family":"Ukkonen","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Alimentary Tract Surgery Tampere University Hospital Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satu\u2010Liisa","family":"Pauniaho","sequence":"additional","affiliation":[{"name":"Emergency Division of Pirkanmaa Hospital District Tampere University Hospital and University of Tampere Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mika","family":"Helminen","sequence":"additional","affiliation":[{"name":"Science Center, Pirkanmaa Hospital District, Tampere and School of Health Sciences University of Tampere Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juhani","family":"Sand","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Alimentary Tract Surgery Tampere University Hospital Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuomo","family":"Rantanen","sequence":"additional","affiliation":[{"name":"Department of Surgery Kuopio University Hospital Box 100 70029 KYS Kuopio Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,8,17]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0000000000000560"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2015.6154"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13017\u2010015\u20100046\u20101"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1308\/003588411X13165261994076"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658\u2010200104000\u201000001"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0b013e31821ad9c4"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00268\u2010011\u20100988\u20108"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00268\u2010015\u20103282\u20103"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.2010.104471"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00268\u2010012\u20101856\u2010x"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12876\u2010015\u20100277\u20103"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11605\u2010011\u20101613\u20108"}],"container-title":["World Journal of Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00268-016-3688-6.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s00268-016-3688-6\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s00268-016-3688-6","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s00268-016-3688-6.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,26]],"date-time":"2023-12-26T16:49:39Z","timestamp":1703609379000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1007\/s00268-016-3688-6"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,8,17]]},"references-count":12,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2017,1]]}},"alternative-id":["10.1007\/s00268-016-3688-6"],"URL":"https:\/\/doi.org\/10.1007\/s00268-016-3688-6","archive":["Portico"],"relation":{},"ISSN":["0364-2313","1432-2323"],"issn-type":[{"value":"0364-2313","type":"print"},{"value":"1432-2323","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,8,17]]}}}
