We evaluated the association between operative time and these image findings: (1) appendicolith, (2) increased intra-abdominal fat density around the appendix, (3) location of the appendix, (4) ascites, (5) abscess formation and (6) maximum appendix outer wall diameter. Appendix location was classified as (#1) just below the anterior abdominal wall; (#2) retrocaecal or retro-ascending colon and (#3) pelvic. Results were analysed using Pearson's correlation coefficient or Mann\u2013Whitney U test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The mean patient age and operative time were 116.24 \u00b1 38.66 months (range, 31\u2013195) and 67.76 \u00b1 31.23 min (range, 30\u2013179), respectively. Ascites was detected in only one case, and no abscess occurred in any patient; therefore, these findings were not analysed. Factors that significantly prolonged the operative time included increased intra-abdominal fat density around the appendix (absent, 59.43 \u00b1 22.14 [range, 30\u2013108] vs. present, 84.43 \u00b1 40.13 [range, 32\u2013179] min;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.03) and retrocaecal or retro-ascending colon appendix (location 1, 40.83 \u00b1 8.35 [range, 30\u201350]; location 2, 99.25 \u00b1 18.56 [range, 74\u2013135]; location 3, 64.54 \u00b1 30.22 [range, 30\u2013179] min;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.01).
