Mobile hysteroscope: A novel technique
Background: Diagnostic hysteroscopy is a valuable tool for the diagnosis of intrauterine pathology. Because of advances in endoscopy that include smaller endoscopes, light emitting diodes displays and camera miniaturization, these procedures have largely moved out of the hospital and into the office. The Minimally Invasive Unit of the 1st Department of Obstetrics and Gynecology of the University of Athens has developed a portable hysteroscopic setup with the utilization of mobile smartphone, a specially designed adaptor and a portable light source.
Aim: The purpose of this study was to evaluate the feasibility and clinical outcome of a new setup for diagnostic hysteroscopy using mobile technology.
Materials and methods: A total of 40 women with indications of diagnostic hysteroscopy were examined according to the new setup using smartphone and portable light source and the standard hysteroscopic setup. The total operating time and the pain perceived by the patients using a Visual Analogue Scale (1-10) were assessed and compared between the two groups. Moreover two independent reviewers, experts in the field of gynecological endoscopy, evaluated the videos acquired from each exam regarding image resolution, color resolution, brightness and overall quality, and whether or not they were acceptable for diagnostic purposes.
Results: All 40 patients underwent a successful diagnostic hysteroscopy with both setup. The total operating time was not different between the two methods (200.75sec vs 201.5sec, p=0,80). The pain perceived by the patients was comparable independently of the hysteroscopic setup utilized (2.78/10 vs 2.7/10, p=0.60). The conventional videos scored higher on every metric relative to portable hysteroscope videos. Image resolution (4.06 vs 3.38, p<0.001), brightness (4.54 vs 3.24, p<0.001), color resolution (4.13 vs 3.35, p<0.001) were all superior when conventional setup was utilized. Overall image quality were comparable between two groups (3.93 vs 3.7, p=0.052). Videos from conventional hysteroscopy were 100% conclusive for correct diagnosis compared to 95% of the videos from mobile hysteroscopy that were considered acceptable for diagnosis.
Conclusions: Mobile hysteroscopy is a valuable alternative to conventional hysteroscopic setup. Mobile adapted endoscopy equipment allows for point of care image capture and video sharing with an ease that has not been previously available. Our hysteroscopic set up is a low-cost video hysteroscopy system with minimal equipment that can capture video of sufficient quality for diagnosis. Systems unprecedented portability can contribute to hysteroscopy expansion in almost every medical office.
