The aim of this study is to evaluate the usefulness of new ports placement inserted from a suprapubic region in laparoscopic LNs dissection around IMA with LCA preservation for sigmoid colon and ractal cancer. Methods : Twenty-two patients who underwent laparoscopic colectomy for sigmoid colon and recal cancer were included. The new ports placement group (n=15, new group) was compared with the basic ports placement group (n=7, basic group). Average number of harvested LNs, total operation time, central LNs dissection time, intraoperative blood loss were compared. Results : There was no significant difference in the average number of harvested LNs. The mean of intraoperative blood loss of new group was significantly lower than that of the basic group (40.0±39.8 ml vs 95.7±81.0 ml, p<0.05). In addition, the mean of operation time of the new group was significantly shorter than that of the basic group (250.0±55.7 min vs 353.4±80.2 min, p<0.05). Conclusions : The new ports placement is useful in laparoscopic LNs dissection around IMA with LCA preservation for sigmoid colon and rectal cancer. journal article Faculty of Medicine Tokushima University 2015-08 VoR application/pdf The Journal of Medical Investigation 3-4 62 223 227 13496867 13431420 AA11166929 AA12022913 https://tokushima-u.repo.nii.ac.jp/record/2004470/files/jmi_62_3-4_223.pdf https://tokushima-u.repo.nii.ac.jp/records/2004470 eng
