Learning Curve of Laparoscopic Colorectal Resections Clinical Trial
Official title:
The Impact of Preoperative Knowledge of the Colonic Vascular Anatomy on the Learning Curve for Laparoscopic Colorectal Resection
Laparoscopic colorectal surgery has been widely accepted worldwide; however, despite the well-known benefits and comparable oncological outcomes, it is still limited by a lack of tactile sensation and a reduced operative field view. In addition, the inconsistency in the number and course of the mesenteric vessels significantly influences the learning curve with 30 to 70 cases required for proficiency. To overcome these limitations, the vascular anatomy can be mapped using CT-angiography, and the images can be processed with rendering software to reconstruct a three-dimensional model of the mesenteric vessels. The aim of this study was to assess the influence of visualizing the three-dimensional vascular anatomy on the learning curve for laparoscopic colorectal surgery.All patients who underwent laparoscopic left or right hemicolectomies between January 2012 and January 2014 were evaluated for inclusion in this study. To assess the influence of preliminary knowledge of colonic vascular anatomy on the learning curve, we considered 2 groups of two surgeons with different levels of experience. In the first group (group A), the surgeons were able to view 3D reconstructions before and during the surgery, while the surgeons in Group B were only able to view the 3D reconstructions after surgery.
