Actually, neither method can be recommended for entry into the abdomen in this population based on our results. If the surgeon has to choose a nonoptical trocar in bariatric surgery, preference for the VNI technique instead of the DTI technique is safer.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/lap.2015.0317","type":"journal-article","created":{"date-parts":[[2015,9,23]],"date-time":"2015-09-23T14:21:14Z","timestamp":1443018074000},"page":"875-879","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Comparison of Direct Trocar Entry and Veress Needle Entry in Laparoscopic Bariatric Surgery: Randomized Controlled Trial"],"prefix":"10.1177","volume":"25","author":[{"given":"Ismail","family":"Ertugrul","sequence":"first","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cuneyt","family":"Kayaalp","sequence":"additional","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehmet Ali","family":"Yagci","sequence":"additional","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatih","family":"Sumer","sequence":"additional","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Servet","family":"Karagul","sequence":"additional","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerem","family":"Tolan","sequence":"additional","affiliation":[{"name":"Inonu University","place":["Turkey"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,11,1]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2005.05.008"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2006.03.020"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2009.10.025"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00464-004-9010-y"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2013.09.012"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1089\/lap.2000.10.325"},{"key":"e_1_3_2_8_2","first-page":"148","article-title":"Comparison of direct trocar insertion of disposable and standard reusable laparoscopic trocars and previous pneumoperitoneum with Veress needle","volume":"78","author":"Nezhat FR","year":"1991","unstructured":"Nezhat FR, , Silfen SL, , Evand D, , Nezhat C.
