Study Objective Our study wishes to appraise the effectiveness of hands-on laparoscopic training sessions using visual analogue scales. Design Evaluation of training was performed via self and tutor assessment questionnaires using visual analogue scale of 10 cm length to measure pre and post-training scores. We measured 5 different skills considered essential in performing safe laparoscopic surgery: manual dexterity, needle handling, tissue handling and knot efficiency. In addition, we measured the ability tie specific laparoscopic knots: surgical, square, spaghetti, Watson. Scores were analyzed for statistical significance using student t-test. Setting Dry lab laparoscopic training boxes. Patients or Participants 9 trainees in Obstetrics and Gynecology, year 3 to 7 of training. Interventions One-day course based on theoretical lectures, video presentations and supervised practice in dry lab laparoscopic suturing. The ratio was one faculty to each two delegates. Measurements and Main Results There was a statistically significant difference in mean scores showing improvement for both candidate self-assessment and tutor assessment pre and post teaching session. The mean scores for generic skills were 3.7 to 5.8 for needle handling (P=0.000), 5.1 to 5.3 for dexterity (P=0.000), 4.8 to 5.3 for tissue handling (P=0.000), 0.3 to 3 for knot efficiency (P=0.000), 0.6 to 2.4 for knot tension (P=0.000). The mean scores recorded by faculty were similar. This was observed irrespective of the trainee's laparoscopic skills proficiency. Conclusion The perception of acquisition of skills and knowledge appears to be similar in candidate's and tutor's assessments. Feedback can quantify competence, confidence and the quality of the course. Although there are validated assessment tools for gynecological laparoscopic skills (SUTT from GESEA training program), there may be a place for simple, reproducible assessment tools for focused training sessions and specific skills development.
