The additional port requirement was associated with a longer operative time (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001), greater intraoperative blood loss (P\u2009&lt;\u20090.0001), and longer postoperative hospital stay (<jats:italic>P<\/jats:italic>\u2009=\u20090.0002). Multivariate analysis revealed male gender (odds ratio: 2.57, <jats:italic>P<\/jats:italic>\u2009=\u20090.0170), prior history of upper abdominal surgery (odds ratio: 5.53,
