Clinical And Anatomical Studies On Laparoscopic Total Mesorectal Excision For Rectal Cancer

Laparoscopic techniques have gained popularity due to the advantages of minimal invasiveness, reduced postoperative pain and improved recovery. However, the acceptance of laparoscopic total mesorectal excision (TME) for rectal cancer has not been as fast as it was for laparoscopic cholecystectomy, colectomy and other laparoscopic operations, owning to the complexity of the techniques required in both open and laparoscopic procedures to achieve TME with sphincter preservation. The concerns have focused on the compliance of oncologic principles of radicality. On current status, the laparoscopic TME is developing relatively slow compared to other laparoscopic colorectal operations for several factors, such as lack of complete and strict acancerous techniques to prove its oncologic criteria, few studies on laparoscopic surgical anatomy, a steep learning curve of the procedures, so on and so forth. This series of studies on laparoscopic TME aim to evaluate the feasibility and radicality, to sum up a sort of acancerous techniques, to present the data of learning curve and analysize the laparoscopic anatomy.Part. 1 Laparoscopic versus open total mesorectal excision for the middle-lower rectal caner: a clinical comparative study...
