title: [Laparoscopic-assisted natural orifice specimen extraction radical left colectomy].
abstract: OBJECTIVE
  To explore the feasibility of laparoscopic-assisted natural orifice specimen extraction radical left colectomy.
  
  
  METHODS
  Retrospective analysis was performed on clinicopathological dada of 15 colorectal patients who were treated by laparoscopic-assisted anal specimen extraction radical left colectomy with self-developed surgical instrument Cai tube between January and September in 2014. Tumor location included descending colon (n=3), the junction of descending colon and sigmoid colon (n=2), the sigmoid colon (n=6) and upper rectum (n=4). Clinical efficacy of patients was observed.
  
  
  RESULTS
  There were no perioperative deaths or postoperative complications, such as anastomotic bleeding or leakage. The median operation time was 257 (range 103-337) min, median blood loss was 50(range 20-200) ml, median time to first flatus was 3 (range 1-5) d and median hospital stay was 14 (range 11-21) d. All the patients had good quality of life and normal defecation function without tumor recurrence or metastasis after 1-8 months of follow-up.
  
  
  CONCLUSIONS
  Laparoscopic-assisted anal specimen extraction radical left colectomy is safe and feasible.
