Assessing the Surgical Skills of Trainees in Learning the LDG

Study Overview
=================
Brief Summary
-----------------
Laparoscopic distal gastrectomy (LDG) is a common surgery in the surgical trainees. However, there is no assessment system to measuring the surgical skill of surgical trainees. The novel surgical assessment system, which called Japanese Operative Rating Scale for Laparoscopic Distal Gastrectomy (JORS-LDG) by the task analysis and the Delphi method have been developed. This study describes assessing the development of surgical skill by JORS-LDG in the initial experience of LDG.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessing the development of surgical skill by JORS-DG in the initial experience of LDG. | The surgical skill and performance of LDG was scored using JORS-DG by a trainee and an instructor. The difference in mean surgical performance score of JORS-DG was evaluated in tree phase. The score about JORS-DG is evaluated on a three or two level scale ( 28items in B-1 reconstruction or 31items in R-Y reconstruction). Maximum of total score is 46 in B-1 reconstruction or 52 in R-Y reconstruction. High score is good surgical skill. Low score is poor surgical skill. | Participants will be followed for the duration of the educational study for 3 years. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessing the value of surgical skill by JORS-DG in the initial experience of LDG and surgical outcome. | Operation time, bleeding , Postoperative complications are compared with average of total score of JORS-LDG. The score about JORS-LDG is evaluated on a three or two level scale ( 28items in B-1 reconstruction or 31items in R-Y reconstruction). Maximum of total score is 46 in B-1 reconstruction or 52 in R-Y reconstruction. High score is good surgical skill. Low score is poor surgical skill. | Participants will be followed for the duration of the educational study for 3 years. | 
| Assessing the value of surgical skill by JORS-DG in the initial experience of LDG and surgical outcome. | Procedures' time in each items of LDG was evaluated for difficulty of surgical technics. The scoring rates in each items of LDG are compared with Procedures' time. The average of score about JORS-LDG is evaluated on a three or two level scale ( 28items in B-1 reconstruction or 31items in R-Y reconstruction). High score is good surgical skill. Low score is poor surgical skill. | Participants will be followed for the duration of the educational study for 3 years. |
