title: [Clinical possibility of low ligation of inferior mesenteric artery and lymph nodes dissection in laparoscopic low anterior resection].
abstract: OBJECTIVE
  To investigate the clinical possibility of low ligation of inferior mesenteric artery (IMA) and lymph nodes dissection in laparoscopic low anterior resection.
  
  
  METHODS
  Data was collected retrospectively from 216 patients who underwent laparoscopic low anterior resection in our hospital from June 2011 to January 2015.Patients were divided into control group (132 cases) and observation group (84 cases). The observation group was treated with low ligation of IMA and lymph nodes dissection, and the control group was cured by high ligation of IMA and lymph nodes dissection. We analyzed the operation time, the number of lymph nodes dissection, the number of lymph nodes removed around the root of IMA, the rate of lymph node metastasis around the root of IMA, the incidence of anastomotic leakage and the ventilation time after the operation.
  
  
  RESULTS
  There was no significant difference between the two group in the pre-operative data, operation time, the number of lymph nodes dissection the number of lymph nodes removed around the root of IMA, the rate of lymph node metastasis around the root of IMA and the incidence of anastomotic leakage (P>0.05). The observation group were significantly better than the control group the in the ventilation time after the operation (P<0.05). The follow up time was 12 to 67 months. The median follow up time was 37 months. One patient in observation group died of cardiovascular disease. One patient in control group died of metastatic carcinoma.
  
  
  CONCLUSIONS
  Detection of low ligation of inferior mesenteric artery and lymph nodes dissection in laparoscopic low anterior resection is safe and practicable, which should be widely applied.
