Background: Although it is widely proposed that surgeons, before introducin
g a novel laparoscopic technique in man, should practice in an appropriate
animal model for acquisition of the necessary technical skills, the effecti
veness of those hands-on training courses are rarely documented.
Methods: In 1995 we have organized eight hands-on training courses for lapa
roscopic anterior interbody spine fusion in an in vivo porcine model. A tot
al of 72 colleagues from 50 different centers of 12 countries participated,
including orthopedic, trauma, visceral, neuro-, and vascular surgeons. Qua
lity and effectiveness of the course were evaluated by a questionnaire afte
r a 1.5- to 2.5-year period.
Results: During this time, 42.2% of the participating centers had applied t
he new technique successfully in man. Centers which participated in the cou
rse with a team that included a skilled laparoscopic surgeon and an orthope
dic or trauma surgeon introduced the technique more frequently to clinical
practice (57.9%) than those represented by only one participant (30.8%). Mo
reover, there was a tendency toward a more frequent introduction of the tec
hnique to clinical practice in centers associated with university hospitals
(57.1% vs. 29.2%), indicating the requirement of a particular infrastructu
re for this complex interdisciplinary procedure. Almost all participants (9
8.3%) agreed that for novel surgical techniques requiring advanced technica
l skills, there should first be training in a large animal model before the
technique is applied in man.
Conclusions: Complex laparoscopic procedures (i.e., laparoscopic spine surg
ery) can be successfully learned by in vivo hands-on training courses. We p
ropose that for refinements and modifications of the technique (e.g., the l
umboscopic approach), there should also first be training in a large animal
model before these are applied in man.
