From February 2014 to March 2017, 251 patients underwent single-plane retroperitoneoscopic adrenalectomy, and their operative outcomes were compared with those of 98 patients who underwent anatomical three-plane retroperitoneoscopic adrenalectomy. Among 35 patients with a body mass index (BMI) of \u226530\u2009kg\/m<jats:sup>2<\/jats:sup>, their operative outcomes were compared between two operative procedures. The demographic data and perioperative outcomes of the patients were statistically analysed. The single-plane and three-plane groups were comparable in terms of estimated blood loss, time to oral intake, hospital stay, and incidence of complications among patients with similar baseline demographics. The single-plane group had a significantly shorter operation time (46.9\u2009\u00b1\u20095.8 vs 54.8\u2009\u00b1\u20097.0\u2009mins, P\u2009&lt;\u20090.0001) and lower analgesia requirement (56\/251 vs 33\/98, p\u2009=\u20090.03). For obese patients with a BMI of \u226530\u2009kg\/m<jats:sup>2<\/jats:sup>, single-plane adrenalectomy was also associated with a significantly shorter operation time(48.1\u2009\u00b1\u20096.2 vs 64.1\u2009\u00b1\u20095.1\u2009mins, p\u2009&lt;\u20090.0001). Single-plane retroperitoneoscopic adrenalectomy is feasible, safe, and effective in the treatment of adrenal masses &lt;5\u2009cm in size and provides a shorter operation time and better pain control than anatomical retroperitoneal adrenalectomy, especially in obese patients.<\/jats:p>","DOI":"10.1038\/s41598-018-22433-3","type":"journal-article","created":{"date-parts":[[2018,2,27]],"date-time":"2018-02-27T15:49:02Z","timestamp":1519746542000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Single-plane retroperitoneoscopic adrenalectomy: a new operative procedure for benign adrenal disease"],"prefix":"10.1038","volume":"8","author":[{"given":"Songchao","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erwei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wansheng","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinjian","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhankui","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2018,3,5]]},"reference":[{"key":"22433_CR1","doi-asserted-by":"publisher","first-page":"740","DOI":"10.1097\/SLA.0000000000000982","volume":"260","author":"M barczy\u0144ski","year":"2014","unstructured":"barczy\u0144ski, M., Konturek, A. & Nowak, W.
