A systematic literature review and meta-analysis comparing outcomes of appendectomy performed by trainees versus trained surgeons found no difference in patient safety and perioperative outcomes. Trainees had longer operating time, but shorter duration of hospital stay and decreased reoperation rate.
Background: Appendectomy is a benchmark operation for trainee progression, but this should be weighed against patient safety and perioperative outcomes. Methods: Systematic literature review and meta-analysis comparing outcomes of appendectomy performed by trainees versus trained surgeons. Results: Of 2086 articles screened, 29 studies reporting on 135,358 participants were analyzed. There was no difference in mortality (Odds ratio [OR] 1.08, P = 0.830), overall complications (OR 0.93, P = 0.51), or major complications (OR 0.56, P = 0.16). There was no difference in conversion from laparoscopic to open surgery (OR 0.81, P = 0.12) and in intraoperative blood loss (Mean Difference [MD] 5.58 mL, P = 0.25). Trainees had longer operating time (MD 7.61 min, P < 0.0001). Appendectomy by trainees resulted in shorter duration of hospital stay (MD 0.16 days, P = 0.005) and decreased reoperation rate (OR 0.78, P = 0.05). Conclusions: Appendectomy performed by trainees does not compromise patient safety. Due to statistical heterogeneity, further randomized controlled trials, with standardized reported outcomes, are required.
