title: [Outcome of laparoscopic radical right hemicolectomy with complete mesocolic resection and D3 lymphadenectomy].
abstract: OBJECTIVE
  To investigate the feasibility of laparoscopic approach for totally mesocolic resection and D3 lymphadenectomy in right colectomy.
  
  
  METHODS
  A retrospective study was conducted to analyze the operating time, blood loss, lymph node retrieval, postoperative complications and converting rate. The relationships of 3-year disease-free survival (DFS), 3-year overall survival (OS) to gender, age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), T-staging, N-staging and TNM classification were also analyzed by Kaplan-Meier surviving curve and Log-rank test.
  
  
  RESULTS
  A total of 111 patients were enrolled in present study. There were 50 male and 61 female patients. The average operating time was (168 ± 42) minutes, blood loss was (81 ± 63) ml, lymph node retrieval was (30 ± 12). The converting rate to open surgery was 1.8%. There was no death within 30 days after operation. The 3-year DFS and 3-year OS was 86.5% and 93.7% respectively. The short-term complications occurred in 17.1% of the patients, including diarrhea (7 cases), ileus (3 cases), urinary infection (3 cases), wound dehiscence (2 cases) and so on. With the T staging progress, DFS and OS in patients showed a gradual decline, but the difference did not reach statistical significance (P > 0.05). TNM classification had relation to DFS (χ(2) = 6.985, P = 0.030), while N-staging showed significant relations both to DFS and OS (χ(2) = 14.397, P = 0.001; χ(2) = 16.699, P = 0.000).
  
  
  CONCLUSIONS
  Laparascopic approach to right hemicolectomy with complete mesocolic resection and D3 lymphadenectomy is safe and has satisfied oncological outcome.
