Optics Letters, 2003
Despite widespread use of multiphoton fluorescence microscopy, development of endoscopes for nonlinear optical imaging has been stymied by the degradation of ultrashort excitation pulses that occurs within optical fiber as a result of the combined effects of group-velocity dispersion and self-phase modulation.

Foot and Ankle Clinics, 2000
Hindfoot pain can be caused by a variety of pathologies; most of these can be diagnosed and treated by means of endoscopy. The main indications are posterior tibial tenosynovectomy, diagnosis of a peroneus brevis length rupture, peroneal tendon athesiolysis, flexor hallucis longus release, os trigonum removal, endoscopic treatment for retrocalcaneal ...

We present a simulation for endoscopic procedures. The anatomy of the patient is represented by 3D polyhedral models, computed from tomographic images. The simulation program can be used as a training system, or for prior simulation of complicated individual cases to reduce the error rate and to decide on the feasibility of biopsies.

Gastrointestinal Endoscopy, 2000
Miniaturization of electronic components may allow the construction of new types of endoscopes that no longer require external wires, cables, or optical fibers. Our aim was to assess the feasibility of wireless endoscopy and to construct experimental prototypes using miniature charge-coupled device cameras, light sources, microwave transmitters, and ...

Gastrointestinal Endoscopy Clinics of North America, 2000
The emergence of pediatric gastroenterology as a subspecialty and improved design and widespread distribution of small diameter endoscopes have combined to foster dramatic expansion in the practice of pediatric endoscopy over the past three decades. Endoscopic evaluation and treatment of gastrointestinal disease in children has led to new diagnoses and

American Journal of Obstetrics and Gynecology, 1952
Abstract This report is an analysis of 191 cases in which endoscopy was employed in an effort to establish the correct diagnosis in patients whose symptoms and findings did not unequivocally warrant abdominal surgery. In 87 per cent of all cases studied, we were able to establish the diagnosis by this method.

Video capsule endoscopy is a major innovation that provides high-resolution imaging of the entire small intestine in its entirety. In the 4 years since its introduction, capsule endoscopy has demonstrated its viability as a first-line investigation in patients with obscure gastrointestinal bleeding after a negative esophagogastroduodenoscopy and ...

Since 1910, when Lespinasse [73] in Chicago was the first surgeon to use an endoscopic device for the treatment of a neurologic disease, various methods of endoscopy have evolved into accepted diagnostic and therapeutic adjuncts of modern neurosurgery.

Although most gastrointestinal endoscopic procedures are performed by gastroenterologists, surgeons often assist in the management of patients with complications. This review provides an introduction to the incidence, prevention, and treatment of complications that may occur after upper endoscopy, colonoscopy, percutaneous endoscopic gastrostomy, and ...
