Laparoscopic surgery for colorectal cancer as a minimally invasive surgery , after more than 10 years of development has made ??tremendous progress . The surgery has a small incision , less blood loss , postoperative pain , quick recovery , the recent fewer complications , shorter hospital stay , etc. , this technology has been gradually understood and accepted . After years of effort laparoscopic surgery for colorectal cancer in the radical , security and long-term survival of tumor therapy has reached a level similar to conventional open surgery , and its short-term efficacy is superior to open surgery , the patient's cellular immune function has a protective effect . Laparoscopic pneumoperitoneum can lead to change the biological behavior of tumor cells , leading to the invasion ability and pneumoperitoneum may cause varying degrees of damage to the peritoneum , resulting in peritoneal mesothelial cell swelling , discontinuity , resulting in base The exposed film , pneumoperitoneum can also lead to liver vascular endothelial cells wrinkles , cracks widened in the cell . The mechanisms of these changes is still not very clear whether the interaction of these factors will promote metastasis and recurrence of the tumor after still need further study . In addition laparoscopic surgery for colorectal cancer there are still relatively complex operation , the surgeon learning curve a long time , expensive surgical supplies inadequate . With the resolution of these issues , we believe that laparoscopic surgery for colorectal cancer is bound to be more doctors and patients to accept .
