Laparoscopic narrow band imaging for detection of occult @entity5 XXXX : a randomized feasibility trial.

@entity5 @entity1 @entity3
BACKGROUND: Selection of @entity5 treatment fundamentally relies on staging of the underlying @entity5 . The aim of this study was to evaluate the feasibility and effectiveness of laparoscopic narrow band imaging (NBI) for operative staging and detection of occult peritoneal @entity5 @entity3 . METHODS: A randomized, controlled feasibility trial with crossover design evaluating adult @entity1 with gastrointestinal or gynecologic @entity5 who have a clinical indication for diagnostic laparoscopy was conducted. Twenty-three @entity1 were randomized to white-light followed by NBI laparoscopy (n  =  11) or NBI followed by white-light laparoscopy (n  =  12) using the Olympus Evis Exera II system. Three @entity1 were excluded from analysis. RESULTS: In all 20 study @entity1 , the abdominal cavity was sufficiently illuminated. An enhanced contrast of microvasculature and organ surface pattern was appreciated. Eight of the 20 @entity1 (40  %) were found to have @entity3 of the peritoneal surface. While NBI did not show any additional peritoneal lesions, 2 of the 63 suspicious-appearing nodules seen on white-light imaging were not visible on NBI (p  =  0.50). The median diameter of all the nodules identified was 2  mm (range 1-50  mm) and was identical with each method. CONCLUSIONS: The information from this feasibility study demonstrated that NBI provides adequate illumination of the abdominal cavity and a unique contrast that enhances microvasculature and architectural surface pattern. The results suggest that NBI laparoscopy is not superior in detecting peritoneal @entity3 compared to standard white-light laparoscopy, but might provide a technology that could be applied for other abdominal pathologies.
