BACKGROUND The advent of laparoscopic surgery has led to the adoption of green
overhead lighting in operating rooms. Green light is purported to minimize glare on video …

Background and study aims Adenoma detection rate (ADR) appears to decrease as the
number of consecutive hours performing procedures increases, and eye strain may be a …

Purpose: The aim of this study was to evaluate the impact of attached shadow cues for
laparoscopic task performance. Methods: We developed a soft-light overhead illumination …

Background Fujifilm developed blue laser imaging (BLI) via a laser light source with a
narrow-band light observation function. It has a brighter BLI bright mode for tumor detection …

BACKGROUND: Light-emitting diodes (LEDs) are being used for a variety of new uses
because of their cost-effectiveness and durability. We therefore considered using white …

Lighting is a critical design element in the construction of functional and efficient operating
rooms. Before the invention of electric lights, the challenge was to adequately light the …

Hypotheses Task performance improves with the use of a balanced degree of shadow and
illumination compared with no or maximum shadow contrast; and overhead shadow-casting …

Methods This was a single center, prospective, randomized, open label study in patients that
presented for routine colonoscopy at an outpatient unit during a six months period. Patients …

The development of gastrointestinal endoscopes has been closely related to innovations in
light sources and observation devices [1]. We anticipated that the lightemitting diode (LED) …

Hypothesis A shadow-inducing laparoscopic system improves task performance. Design
Experimental study was carried out using the Dundee Endoscopic Psychomotor Tester for …
