The LMA\u00ae Gastro\u2122 Airway, a novel dual channel supraglottic airway technique, has been described as such a device. Its utility alongside sedation with low flow nasal cannula and general anaesthesia (GA) with intubation for endoscopic retrograde cholangiopancreatography (ERCP) procedures was evaluated.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>Details of all the ERCPs performed in our institution from March 2017 to June 2018 were carefully recorded in the patients\u2019 electronic case records. Data on the successful completion of ERCP through LMA\u00ae Gastro\u2122 Airway; any difficulty encountered by the gastroenterologists; and adverse events were recorded. Episodes of hypoxia (SpO<jats:sub>2<\/jats:sub>\u2009&lt;\u200992%) and haemodynamic parameters were compared across the three groups: LMA\u00ae Gastro\u2122 vs. sedation with low flow nasal cannula vs. GA with an endotracheal tube (ETT).<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>One hundred seventy-seven ERCP procedures were performed during the study period. The LMA\u00ae Gastro\u2122 Airway was employed in 64 procedures (36%) on 59 patients. Of these 64 procedures, ERCP was successfully completed with LMA\u00ae Gastro\u2122 Airway in 63 (98%) instances, with only one case requiring conversion to an endotracheal tube. This instance followed difficulty in negotiating the endoscope through LMA\u00ae Gastro\u2122 Airway. No episodes of hypoxia or hypercapnia were documented in both LMA\u00ae Gastro\u2122 and GA with ETT groups. One sedation case with nasal cannula was noted to have hypoxia. Adverse intraoperative events were recognised in 2 cases of LMA\u00ae Gastro\u2122: one had minimal blood stained secretions from the oral cavity that resolved with suctioning; the other developed mild laryngospasm which resolved spontaneously within a few minutes.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusion<\/jats:title>\n<jats:p>In patients undergoing ERCP, the LMA\u00ae Gastro\u2122 airway demonstrated a high success rate for ERCP completion. Ventilation was well maintained with minimal intraoperative and postoperative adverse events. This technique may have a role in higher risk groups such as high ASA (American Society of Anesthesiologists) status, or those with potential airway difficulties such as high body mass index and those with known or suspected sleep apnoea.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s12871-020-01019-5","type":"journal-article","created":{"date-parts":[[2020,5,13]],"date-time":"2020-05-13T09:19:35Z","timestamp":1589361575000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["LMA\u00ae Gastro\u2122 Airway for endoscopic retrograde cholangiopancreatography: a retrospective observational analysis"],"prefix":"10.1186","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3602-4103","authenticated-orcid":false,"given":"Andre","family":"Tran","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4654-9608","authenticated-orcid":false,"given":"Venkatesan","family":"Thiruvenkatarajan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5860-0063","authenticated-orcid":false,"given":"Medhat","family":"Wahba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4900-9287","authenticated-orcid":false,"given":"John","family":"Currie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7819-5317","authenticated-orcid":false,"given":"Anand","family":"Rajbhoj","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8498-9861","authenticated-orcid":false,"given":"Roelof","family":"van Wijk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1179-0533","authenticated-orcid":false,"given":"Edward","family":"Teo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7830-5774","authenticated-orcid":false,"given":"Mark","family":"Lorenzetti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6925-4277","authenticated-orcid":false,"given":"Guy","family":"Ludbrook","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,5,13]]},"reference":[{"issue":"2","key":"1019_CR1","doi-asserted-by":"publisher","first-page":"137","DOI":"10.1016\/j.cgh.2009.07.008","volume":"8","author":"GA Cot\u00e9","year":"2000","unstructured":"Cot\u00e9 GA, Hovis RM, Ansstas MA, Waldbaum L, Azar RR, Early DS, Edmundowicz SA, Mullady DK, Jonnalagadda SS.
