S. Bouchard et al., TECHNOLOGY-ASSESSMENT IN LAPAROSCOPIC GENERAL-SURGERY AND GASTROINTESTINAL ENDOSCOPY - SCIENCE OR CONVENIENCE, Gastroenterology, 110(3), 1996, pp. 915-925
Gastrointestinal endoscopy and laparoscopic general surgery have been
significantly affected by the emergence of new techniques. These two d
isciplines share many similarities, including the use of sophisticated
and expensive technologies. Their proper assessment is essential beca
use they are developed amidst ever-decreasing health cave budgets. Gas
troenterologists and general surgeons must both participate in such ev
aluations and feel confident in interpreting pertinent published data.
The present review uses a clinician's point of view with relevant exa
mples to discuss the methodologies adopted in technology assessment an
d to highlight common pitfalls encountered in study design, patient se
lection, timing and selection of the study, blinding, and outcome meas
urement. Cost and statistical considerations, as well as ethical issue
s, are also reviewed in the context of technology assessment.
