Abstract
BACKGROUND: How to efficiently train and transfer skills in laparoscopic colorectal surgery is unclear. Errors are rarely avoidable during learning but may incur patient morbidity. Multi-modality training with a modular operative approach provides proficiency-based structured task-specific training in a sequential manner, fragmenting complex laparoscopic colorectal procedures by difficulty allowing more than one trainee to gain experience irrespective of prior experience. This study assessed multi-modality training and its effect on proficiency gain in laparoscopic colorectal fellows. METHODS: A prospective study of 750 consecutive laparoscopic colon and rectal resection training cases assessing proficiency gain using a modified direct observation of procedural skills (DOPS) (behaviors-assessment) and weighted global modular attainment score (GMAS) (maneuvers-assessment) was carried out. Two mentors delivered training in a standardized format from 2008. Consequential intra-operative errors (requiring a corrective maneuver to permit further progression of the operation) were recorded. Eight Laparoscopic Fellows were assessed in six-month periods over 4 years. Primary outcome was proficiency gain measured by cumulative sum (CUSUM) analysis with boot-strapping comparing weighted GMAS and modified DOPS assessment. Morbidity (Clavien-Dindo classification), and consequential errors were submitted to similar analysis to assess significant variations during the training period. RESULTS: Fellows were trained on over 100 laparoscopic colorectal resections in a six Fellowship month period. Proficiency gain was identifiable in the DOPS and GMAS with 32 (99 % CI 25-37) and 39 (99 % CI 32-44) cases, respectively. Two- versus single-mentor training improved proficiency gain 35 (99 % CI 30-43) versus 55 (99 % CI 50-60). Overall consequential error rate and major morbidity rate (CD III-IV) were stable over time at 25 and 8.7 %, respectively. CONCLUSIONS: Multi-modality training with modular operative training and technique standardization shortens the time to proficiency gain with low morbidity accepting an intra-operative consequential error rate of 25 %.
