Participants included 626 infants who underwent a pyloromyotomy for HPS. We collected data on presentation features (age, weight, clinical signs, blood gas results, ultrasound findings) and postoperative outcomes (length of stay (LOS), complications, time to first postoperative feed).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No trend was identified during the study period with regards to age, weight, biochemical findings (pH, chloride, base excess) or pre\u2010operative ultrasound measurements. There was a downtrend in the number of palpated tumours over time, with a mean of 36% of tumours clinically palpated. Pyloric wall thickness had a moderate association with LOS in patients admitted for &gt;8 days (correlation\u2009= 0.4752) but had a weak negative association with shorter lengths of stay (\u22648 day, correlation\u2009=\u2009\u22120.094). Overall, median time to first feed was 7.80\u2009h and improved yearly during the study period (hazard ratio\u2009= 1.07).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Patients presenting with HPS are not being identified at an earlier age or with fewer biochemical derangements, in contrast to our initial perceptions. Subsequently, biochemical derangements can still play an important role in the diagnosis of HPS, and attention needs to be given to fluid management and electrolyte correction in all patients with HPS.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jpc.14372","type":"journal-article","created":{"date-parts":[[2019,1,24]],"date-time":"2019-01-24T23:31:23Z","timestamp":1548372683000},"page":"1183-1187","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Presentation and outcomes in hypertrophic pyloric stenosis: An 11\u2010year review"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8305-9208","authenticated-orcid":false,"given":"Toby I","family":"Vinycomb","sequence":"first","affiliation":[{"name":"Department of Paediatric Surgery Royal Children's Hospital  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirby","family":"Laslett","sequence":"additional","affiliation":[{"name":"Faculty of Medicine Nursing and Health Sciences Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stella M","family":"Gwini","sequence":"additional","affiliation":[{"name":"School of Public Health and Preventive Medicine Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4747-6025","authenticated-orcid":false,"given":"Warwick","family":"Teague","sequence":"additional","affiliation":[{"name":"Department of Paediatric Surgery Royal Children's Hospital  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4438-0263","authenticated-orcid":false,"given":"Ramesh M","family":"Nataraja","sequence":"additional","affiliation":[{"name":"Department of Paediatric Surgery Monash Children's Hospital  Melbourne Victoria Australia"},{"name":"Department of Paediatrics, School of Clinical Sciences, Faculty of Medicine, Nursing and Health Sciences Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,1,24]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.ede.0000192032.83843.c9"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2011-2845"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2007.128090"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.sempedsurg.2016.05.004"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.34.173.20"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800730529"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02653256"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197705192962006"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/jpc.12027"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/ped.12860"},{"key":"e_1_2_6_12_1","unstructured":"Australian Bureau of Statistics.3301.0 \u2010 Briths Australia 2015.
