title: Long-term results of laparoscopy-assisted radical right hemicolectomy with D3 lymphadenectomy: clinical analysis with 177 cases.
abstract: OBJECTIVE
  To study the feasibility, safety, and short-/long-term outcomes of laparoscopy-assisted right hemicolectomy with D3 lymphadenectomy for colon cancer.
  
  
  METHODS
  The clinical data of 177 cases that underwent laparoscopy-assisted radical right hemicolectomy with D3 lymphadenectomy for colon cancer between Jun 2003 and Sep 2010 was collected; the safety of operation, status of recovery, complication, oncological outcomes, and results of short-/long-term follow-up were analyzed.
  
  
  RESULTS
  No case died in this study; five cases (2.82 %) were converted to open surgery. Four cases (2.26 %) underwent hand-assisted laparoscopic right hemicolectomy. The average operation time was 133 ± 36 min, and the blood loss was 94 ± 34 ml. The average time for passage of flatus, liquid food eating, and hospitalization were 2.1 ± 0.7, 3.2 ± 0.5, and 10.4 ± 2.7 day, respectively. The total number of lymph nodes removed was 15.2 ± 10.1. Postoperative complications were observed in 23 of 177 patients (12.99 %). The median follow-up period was 54 months; port-site recurrence was observed in one patient; local recurrence was found in five cases (2.82 %); distant metastasis was found in 21 cases (11.86 %). The cumulative overall survival of all stages at 12, 36, 60, and 72 months was 97.18 %, 83.73 %, 70.37 %, and 68.99 %, respectively. The cancer-specific survival was 98.73 % (12 months), 87.81 % (36 months), and 80.17 % (60 months).
  
  
  CONCLUSIONS
  Laparoscopy-assisted right hemicolectomy with D3 lymphadenectomy can be successfully performed for right colon cancer with the advantages of minimally invasive surgery. Moreover, the results implied appropriate short- and long-term outcomes.
