BackgroundA variety of surgical treatment methods for carpal tunnel syndrome are introduced recently, including open surgery, endoscopic and the Knifelight. It is hypothesized that Knifelight method could decrease scar tenderness and time before return to daily activities for patients and is accompanied with less disturbance to fine sensory nerves.ObjectivesTo compare the Knifelight instrument and open carpal tunnel release with respect to scar length, operation duration, recovery time needed before return to work and amount of pain three weeks after surgery in patients with neurophysiologically confirmed carpal tunnel syndrome.Patients and MethodsFifty nine patients with indication for carpal tunnel release randomly assigned into two groups: open (n=30) or Knifelight (n=29). The patients compared regarding scar length, operation duration, time to return to daily activities and amount of pain at three weeks after operation based on Visual Analog Scale.ResultsThere was no significant differences regarding age and sex in the two groups. The scar length, operation duration and time before return to daily activities were significantly lower in the Knifelight group. Although the mean visual analogue scale of Knifelight group found to be lower than the other, it was not statistically significant.ConclusionsThe Knifelight technique is accompanied with advantages over the open surgery regarding operation time, scar length and time to return to daily activities. The pain relieve based on Visual Analog Scale was not statistically different from conventional open surgery.
An objective, quantitative approach to measuring foveolar hyperplasia in adults was successfully applied to pediatric biopsies and yielded a richer characterization of gastric pathology in children. Foveolar hyperplasia appears to be a generalized phenomenon in the presence of pediatric Helicobacter pylori gastritis but is limited to the antrum in non-Helicobacter pylori gastropathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
