[Evaluation of basic laparoscopic training under 5A teaching mode].

To evaluate the rationality and effectiveness of basic laparoscopic training under 5A teaching mode. A prospective randomized controlled study was conducted. The teaching records of 70 trainees who received basic laparoscopic traning at the Laparoscopic Surgical Training Base in Chinese PLA General Hospital from July to December 2019 were analyzed. All the trainees participating in the laparoscopy training had obtained the national practicing physician certificates, including 12 junior physicians of our center, 9 intermediate physicians of our center, 19 advanced physicians, 13 postgraduate students, 8 doctoral students, and 9 surgical standardized training physicians. A random number table method was used to divide all the trainees into two groups: the traditional teaching group or the 5A teaching group (35 people in each group). In the traditional teaching group, the training of 4 modules of " precise beans, quincuncial piles, ring positioning and knot-tying suture" modules according to a fixed sequence and schedule was carried out. Each module had a learning time of 8 hours. In the 5A teaching group, the training started from five dimensions of analysis, aim, accomplishment, appraise and advance. Before conducting each stage of training, the actual operation ability of the trainees was tested, each class hour was designed individually, accurate teaching was conducted to the trainees, the ability of the trainees was evaluated dynamically, and the previous steps were cycled periodically based on class hours. The operating time and pass rate of trainees of two groups in the basic operation module of laparoscopy were statistically analyzed, and a hierarchical analysis of related influencing factors was conducted. The time of above modules before training in the 5A teaching group and the traditional teaching group was similar (all >0.05). After definitive training, the time required for trainees in 5A teaching group and traditional teaching group to complete the 4 modules was shortened to varying degrees. Compared to traditional teaching group, 5A teaching group spent less time in completing each project [precise beans: (63.2±10.1) seconds vs. (83.6±18.7) seconds, quincuncial piles: (56.2±7.3) seconds vs. (101.4±31.7) seconds, ring positioning: (84.2±13.7) seconds vs. (127.3±28.5) seconds, knot-tying suture: (263.2±41.8) seconds vs.(428.8±95.2) seconds, all <0.05], and had higher pass rates [precise beans: 97.1% (34/35) vs. 80.0% (28/35), quincuncial piles: 91.4% (32/35) vs.71.4% (25/35), ring positioning: 100.0% (35/35) vs. 82.9% (29/35), knot-tying suture: 77.1% (27/35) vs. 60.0% (21/35), all <0.05]. Among the junior trainees (junior physicians of our center, postgraduate students, doctoral students, and standardized surgical training physicians) and intermediate trainees (intermediate physicians of our center and advanced physicians), the 5A teaching group completed 3 modules (quincuncial piles, ring positioning and knot-tying suture) faster than the traditional teaching group [junior trainees: quincuncial piles (76.4±12.4) seconds vs. (139.8±41.6) seconds, ring positioning (92.2±20.5) seconds vs. (131.3±28.4) seconds, knot-tying suture (293.8±66.7) seconds vs. (444.3±103.3) seconds; intermediate trainees: quincuncial piles (51.4±5.9) seconds vs. (94.7±8.6) seconds, ring positioning (63.9±13.5) seconds vs. (87.5±18.6) seconds, knot-tying suture (210.1±35.6) seconds vs. (367.5±54.9) seconds, all <0.05]. 5A teaching mode can acheive better training results compared with the traditional teaching mode in basic laparoscopic training, and is worthy of further popularization and application.
