BACKGROUND: Laparoscopic appendectomy is a common procedure and introduced early in general surgical training. How internal (i.e. surgeon's experience) or external (i.e. disease severity) may affect procedure performance is not well-studied. The aim of this study was to evaluate factors that may have an influence on the performance scores for surgical trainees.
METHODS: A prospective, observational cohort study of laparoscopic appendectomies performed by surgical trainees (experience < 4 years) operating under supervision. Trainers evaluated trainees' overall performance on a 6-point scale for proficiency. Perioperative data were recorded, including appendicitis severity, operating time and the overall difficulty of the procedure as assessed by the trainer. A "Challenging" procedure was defined as a combination of either/or "perforation" and "difficult". Trainees who had performed > 30 appendectomies were defined as "experienced". The trainees were asked if they had used simulation or web-based tools the week prior to surgery.
RESULTS: 142 procedure evaluation forms were included of which 19 (13%) were "perforated", 14 (10%) "difficult" and 24 (17%) "Challenging". Perforated appendicitis was strongly associated with procedure difficulty (OR 21.2, 95% CI 6.0-75.6). Experienced trainees performed "proficient" more often than non-experienced (OR 34.5, 95% CI 6.8-176.5). "Difficult" procedures were inversely associated with proficiency (OR 0.1, 95% CI 0.0-0.9). In "Challenging" procedures, identifying the appendix had lowest proficiency (OR 0.4, 95% CI 0.1-0.9). The procedures assessed as "difficult" had significantly longer operating time with a median (IQR) of 90 (75-100) min compared to 59 (25-120) min for the non-difficult (p < 0.001).
CONCLUSION: Both internal and external factors contribute to the performance score. Perforated appendicitis, technical difficult procedures and trainee experience all play a role, but a "difficult" procedure had most overall impact on proficiency evaluation.
