Videomimicography in displaying skills of retroperitoneal laparoscopic radical nephrectomy in a self control manner / 第二军医大学学报

ABSTRACT

Objective: To use videomimicography to display the skills of retroperitoneal laparoscopic radical nephrectomy in a self control manner, so as to help the beginners to learn the skills quickly. Methods: The videos of 147 cases of retroperitoneal laparoscopic radical nephrectomy for renal-cell carcinomas (T1 N0 M0), which were performed by a surgeon in our department from Jan. 1, 2002 to Dec. 31, 2006, were retrospectively analyzed. The first 30 cases were compared with the last 30 cases in terms of operative manipulation, outcomes, problems in operation, and complications after operation. The difficulties in learning retroperitoneal laparoscopic radical nephrectomy from videos were discussed. Results: There were no differences between the two patient groups in age, gender, the location or size of the tumors. The bleeding volumes, operation time, frequencies of transferring to open surgery, and addition of Trocar in the first 30 patients were significantly more than those in the last 30 patients (all P<0.01). Results of videomimicography demonstrated that the beginners had a poor anatomic knowledge, the exposure and tissue isolation were not enough, and they had a poor basic skill in manipulating laparoscope. Conclusion: Videomimicography can better display the difficulties in retroperitoneal laparoscopic radical nephrectomy in a self control manner, which can help the beginner to understand the operating skills; the method is worth popularizing.
