Assessment and COMPARISON OF digital image quality for peritoneoscopy USING THE flexible endoscope AND the rigid LAPAROSCOPE FOR NOTES PROCEDURES
Introduction: Although NOTES peritoneoscopy has been widely performed, the image quality acquired with flexible endoscopes has never been directly compared with the current gold standard of the rigid laparoscope. The purpose of the current study was to assess and compare the image quality derived from the flexible endoscope versus the rigid laparoscope during exploratory peritoneoscopy.… Continue Reading

Audio-visual training system is simple and useful method for trainees with various skill levels in laparoscopically assisted surgery.
(BACKGROUND) Traditionally, surgical residents learn and master surgical skills while they are doing operation under the proper direction of senior staff or supervisors. In the case of laparoscopically assisted surgery, in which learning curve depends on efficient instruction due to the complicated procedures, both operator and director can share the same image as well as… Continue Reading

Better Performance of Laparoscopic Simulator Tasks with High Definition Camera Technology: A Pilot Study
Background: The availability of a High Definition (HD) laparoscopic camera improves image quality, however whether this translates into improved performance compared to a standard camera (SD) is not known. We investigated whether performance in a laparoscopic simulator would be affected by the use of a HD camera.Methods: 5 subjects (2 surgical residents and 3 laparoscopic… Continue Reading

Bird\’s-Eye View: A Visual Adjunct for Spatial Orientation Improves Efficacy of NOTES Procedures
Introduction: Although NOTES research has shown substantial progress in recent years, some technical challenges remain. Among them is the suboptimal spatial orientation of the flexible endoscope within the peritoneal cavity. Due to the endoscope’s lack of rigidity, the ability to retroflex, and, more importantly, the coupling of the image source to the end effector instruments,… Continue Reading

Blind flank trocar placement to achieve pneumoperitoneum
Aim: To evaluate the safety of blind Lateral Port Entry (LPE) to achieve a pneumoperitoneum for laparoscopic surgery.Background: Surgeons are understandably concerned about obtaining pneuomoperitoneum due to the risks of bowel and vascular injury, particularly in patients who have had previous midline surgery with possible adhesions. Furthermore laparoscopic mesh repair of incisional hernais within midline… Continue Reading

Burst Pressures in Gastric Closure – a NOTES Comparison Study of Looped T-Anchors vs. Endoclips in the Explanted Porcine Stomach
Background: A reliable, secure closure of the gastrotomy remains a fundamental challenge in transgastric NOTES procedures. Gastrotomy closure using endoscopic clips is unreliable, technically difficult, and expensive. Few tests of the integrity of these closures have been published. We compared burst pressures in gastric explants utilizing looped T-anchors and endoscopic clips.Methods: In nine explanted porcine… Continue Reading

C-reactive protein concentrations before and after gastric bypass surgery inversely correlate with omental gene expression of adiponectin.
Adipose tissue is a key regulator of C-reactive protein (CRP), an inflammatory marker linked to atherosclerosis. Adiponectin, the most abundant adipokine is also an importantl factor involved in the inflammatory state of obesity. The aim of the study was to assess the impact of gastric bypass surgery (GBS) on the CRP levels and its relation… Continue Reading
