The operative time (337\u2009\u00b1\u2009165 vs 239\u2009\u00b1\u2009107\u2009min,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.010) was significantly different between PDM and non\u2010PDM groups, but bleeding loss was not different (108\u2009\u00b1\u200997\u2009ml vs 53\u2009\u00b1\u2009142\u2009ml,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.259). In PDM patients, in addition to abnormal fixation of the sigmoid\u2010descending colon junction, adhesion of the mesentery of the colon and small intestine in 100%, and adhesion between the mesocolon in 33% patients was confirmed intraoperatively. Ileus was more common in the PDM group (two cases, 22%) and in the non\u2010PDM group (10 cases, 5.6%), but there was no significant difference in overall postoperative complications between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.215).

The left colonic artery (LCA) could not be preserved in six patients in the PDM group, one of whom had anastomotic leakage and two of whom required additional resections due to intraoperative intestinal blood flow failure.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PDM prolonged operative times and duration of postoperative stay in laparoscopic surgery for left\u2010sided colon and rectal cancer.
