Abstract
High morbidity rates related to anastomotic leakage and other factors restrict the application of laparoscopic rectal excision The aim of the present study was to assess the effect of left colonic artery LCA preservation on postoperative complications after laparoscopic rectal excisionData from 888 patients from 28 leading hospitals in Japan who underwent laparoscopicassisted sphincterpreserving resection of middle and low rectal cancers between 1994 and 2006 were analyzed The effects of LCA preservation were analyzed among all anterior resection AR cases n = 888 and among AR cases with radical lymph node excision n = 411Among all AR cases the tumor size number of lymph nodes collected with evidence of metastasis TNM factor and TNM staging were smaller in the LCA preservation group Regarding complications the rate of anastomotic leak was significantly higher in the LCA nonpreservation group among all AR cases as well as among AR cases with radical lymph node excision Nevertheless there was no difference in survival rate between LCA preservation group and nonpreservation group as measured by the Kaplan–Meier methodThis work was supported in part by the Japanese Society for Cancer of the Colon and Rectum The following institutions and surgeons are the members of the Japan Society of Laparoscopic Colorectal Surgery who participated in this multicenter study Kokuba Y Kitasato University current affiliation St Marianna University Yokohama City Seibu Hospital Kawamura Y Saitama Medical Center Jichi Medical School Miyajima N Teikyo University Hospital Mizonokuchi current affiliation St Marianna University Toyoko Hospital Fukunaga M Juntendo Urayasu Hospital Juntendo University Kudo S Tanaka J Northern Yokohama Hospital Showa University Tanigawa N Okuda J Osaka Medical University Nagai H Horie H Jichi Medical School Otsuka K Iwate Medical University Fukunaga Y Osaka City General Hospital current affiliation Cancer Institute Hospital Bandou H Ishikawa Prefectural Central Hospital Kitano S Inomata M Oita University Kubo Y Shikoku Cancer Center Ichihara T Nishinomiya Municipal Central Hospital Hasegawa H Keio University Yamamoto S National Cancer Center current affiliation Hiratsuka City Hospital Ikoma S Ikoma Hospital Nishiyama Y National Hospital Organization Sagamihara National Hospital Enomoto M Tokyo Medical and Dental University Yamaguchi S Shizuoka Cancer Center current affiliation Saitama Med University International Medical Center Sekimoto M Osaka University current affiliation Osaka National Hospital Masaki T Kyorin University Idani H Fukuyama City Hospital Sumiyama Y Saida Y Toho University Ohashi Medical Center Munemoto Y Fukui Saiseikai Hospital Maeda K Hanai K Fujita Health University Kuroyanagi H Cancer Institute Hospital current affiliation Toranomon Hospital Ueda K Kinki University
