Clinical analysis of the application of hand-assistant laparoscopic surgery with D3 lymph node dissection for right colon cancer

Objective: This retrospective study aims to compare the clinical outcomes between conventional laparotomy and hand-assisted laparoscopic surgery (HALS) with D3 lymph node dissection in the treatment of right colon cancer and to analyze and evaluate the feasibility and safety of HALS with D3 lymph node dissection. Methods: Among 63 patients, 35 underwent HALS with D3 lymph node dissection (study group) and 28 underwent conventional laparotomy (control group). The operation durations, the number of lymph node harvest, bleeding volumes, postoperative draining volumes, recovery time of gastrointestinal function, hospitalization time, hospitalization expenses, postoperative complications rate and cosmetic satisfactory scores were compared between the two groups. Results: The bleeding volume, postoperative draining volume and the hospitalization expenses in study group were lower than control group. The hospitalization time in study group was shorter than control group. The cosmetic satisfactory scores in study group were higher than in control group. The number of lymph node harvest, the recovery time of gastrointestinal function and the postoperative complications rate were no significantly differences between the two groups. Conclusion: HALS with D3 lymph node dissection got the same clinical curative effect compared with traditional open surgery for right colon cancer.
