Three groups were identified: a complete laparoscopic surgery group (LG), a conversion to open group (CG), and a primary open group (OG). After univariate comparisons, a multivariate analysis was conducted to identify the predictive factors for conversion.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Of the 175 patients that underwent surgery for PPU, 104 (59.4%) received a laparoscopic-first approach, and 27 (25.9%) required a conversion to open surgery. Patients treated directly with an open approach were older (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), had more comorbidities (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), and more frequently had a previous laparotomy (<jats:italic>p<\/jats:italic>\u2009=\u20090.0001). In the OG group, in-hospital mortality and ICU need were significantly higher, while the postoperative stay was longer. Previous abdominal surgery (OR 0.086, 95% CI 0.012\u20130.626; <jats:italic>p<\/jats:italic>\u2009=\u20090.015), ulcer size (OR 0.045, 95% CI 0.010\u20130.210; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), and a posterior ulcer location (OR 0.015, 95% CI 0.001\u20130.400; <jats:italic>p<\/jats:italic>\u2009=\u20090.012) were predictive factors for conversion to an open approach.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This study confirms the benefits of the laparoscopic approach for the treatment of PPUs.
