ENDOSCOPIC DIAGNOSIS OF INTRADUCTAL PAPILLARY‐MUCINOUS NEOPLASM OF THE PANCREAS BY MEANS OF PERORAL PANCREATOSCOPY USING A SMALL‐DIAMETER Videoscope AND NARROW‐BAND IMAGING
Digestive Endoscopy, 2010Co-Authors: Tomihiro Miura, Naoki Okano, Yoshinori Igarashi, Kazumasa Miki, Yoichiro OkuboAbstract:Background: Intraductal papillary-mucinous neoplasm (IPMN) is an intraductal tumor in which the mucin-producing epithelium shows proliferated papillary and a wide variety of pathological changes ranging from hyperplasia to adenocarcinoma. Therefore, it is important to determine whether an IPMN is benign or malignant. In the present study of patients with IPMN, the protrusion was observed by a peroral pancreatoscopy (PPS) using a small-diameter Videoscope and narrow-band imaging (NBI). We carried out the differential diagnosis of benign lesion to malignant lesion. Methods: Between April 2003 and May 2009, PPS using a small-diameter Videoscope by means of NBI was carried out on 21 hospitalized patients with IPMN (10 cases of adenocarcinoma, 11 cases of adenoma or hyperplasia; 14 males and seven females, with a mean age of 69.4 years). Results: Fifteen focal lesions of the 16 cases in the head of the pancreas (93.7%) and four focal lesions of the five cases in the pancreatic body (80%) were observable, whereas two lesions (adenocarcinoma in the pancreatic body, and adenoma in the uncus of pancreas) were not observable. Endoscopically, seven cases were classified as villous type and two cases as vegetative type, and nine cases were diagnosed as adenocarcinoma. Ten cases with sessile type or semipedunculated type were diagnosed as adenoma or hyperplasia. Vascular patterns and protrusions were detected more clearly in the NBI images than under white light observation. Conclusions: When combined with a Videoscope and NBI, pancreatoscopy provided a clear image and was useful for evaluating whether the IPMN was benign or malignant.

peroral cholangioscopy using a new thinner Videoscope chf b260
Digestive Endoscopy, 2005Co-Authors: Yoshinori Igarashi, Naoki Okano, Daisuke Satou, Tomihiro Miura, Kazumasa MikiAbstract:The CHF-B260 Videoscope has a 3.4 mm outer diameter, 1.2 mm forceps channel, and two-way angulations function (70° up and 70° down). Peroral cholangioscopy (POCS) was performed using the CHF-B260 in 13 patients who were admitted to our hospital between October 2002 and June 2004. The CHF-B260 was successfully inserted into the bile duct in all cases. Clear images were obtained in 11 patients. Endoscopic images for two cases of malignant stricture due to metastasis of colon cancer and gallbladder cancer were not clear because of bleeding from the tumors. POCS was performed safely in all patients without any complications. POCS with the CHF-B260 was very useful for the diagnosis of biliary disorders. If the outer diameter and biopsy channel of CHF-B260 are improved, POCS will become even more effective for the diagnosis of biliary disorder.

A Wireless Robot for Networked Laparoscopy
2013Co-Authors: Cristian A. Castro, Adham Alqassis, Thomas Ketterl, Peter P. Savage, Sharona Ross, Sara Smith, Yu Sun, Er Rosemurgy, Richard D GitlinAbstract:Abstract—State-of-the-art laparoscopes for minimally invasive abdominal surgery are encumbered by cabling for power, video, and light sources. Although these laparoscopes provide good image quality, they interfere with surgical instruments, occupy a trocar port, require an assistant in the operating room to control the scope, have a very limited field of view, and are expensive. MARVEL is a wireless Miniature Anchored Robotic Videoscope for Expedited Laparoscopy that addresses these limitations by providing an inexpensive in vivo wireless camera module (CM) that eliminates the surgical-tool bottleneck experienced by surgeons in current laparoscopic endoscopic single-site (LESS) procedures. The MARVEL system includes 1) multiple CMs that feature a wirelessly controlled pan/tilt camera platform, which enable a full hemisphere field of view inside the abdominal cavity, wirelessly adjustable focus, and a multiwavelength illumination control system; 2) a master control module that provides a near-zero latency video wireless communications link, independent wireless control for multiple MARVEL CMs, digital zoom; and 3) a wireless human–machine interface that gives the surgeon full control over CM functionality. The research reported in this paper is the first step in developing a suite of semiautonomous wirelessly controlled and networked robotic cyberphysical devices to enable a paradigm shift in minimally invasive surgery and other domains such as wireless body area networks.

Laser identification of residual microislands of calculus and their removal with chelation
Journal of Periodontology, 2020Co-Authors: Stephen K. Harrel, John C. Tunnell, Thomas G. Wilson, William V. StenbergAbstract:BACKGROUND During Videoscope-assisted minimally invasive surgery which uses a high magnification Videoscope to treat periodontal defects, small areas resembling calculus are detected remaining on root surfaces following scaling. These are clinically termed microislands of calculus, which are removed by the use of a chelating agent. This material has not been verified as calculus and the ability of a chelating agent to remove calculus has not been proven. The purpose of this ex vivo study is to verify if the material is calculus and to determine if calculus is removed with a chelating agent. METHODS Extracted teeth (n = 22) with heavy calculus on root surfaces were selected. A 5-mm2 area containing calculus was scribed on each root. Digital Videoscope images were made of the marked areas using only white light and also with only a 655-nm diode laser that causes calculus to fluoresce. The marked areas were root planed until no calculus was visible with 3.5× surgical loupes. Digital images were again made. The test area was then burnished with a chelating agent (EDTA) for 30 seconds and images again made. Using the images, the percentage of the marked root surface containing calculus was calculated. RESULTS Calculus remained on the roots surfaces after they were judged to be clean using 3.5× loupe magnification. Remaining calculus was reduced after burnishing for 30 seconds with EDTA. CONCLUSIONS Calculus remains on root surfaces judged to be calculus free using surgical loupes for visualization. Small areas of calculus are reduced or eliminated with a chelating agent.

Comparison of a Dental Operating Microscope and High-resolution Videoscope for Endodontic Procedures.
Journal of Endodontics, 2020Co-Authors: Basil Al Shaikhly, Stephen K. Harrel, Mikhail Umorin, Robert A. Augsburger, Poorya JalaliAbstract:Abstract Introduction The purpose of this study was to compare a dental operating microscope (DOM) with a high-resolution Videoscope (VS) in terms of depth of field (DOF), resolution, and effect on fine motor skills. Methods Two observers used test targets to measure the resolution and DOF of the DOM and the VS. In addition, 18 participants (12 dental students and 6 endodontic residents) performed an accuracy test on a manikin head using DOM, VS, or loupes. Each participant completed a posttest survey. Results The 3 magnifications of the DOM had higher resolutions and DOF (resolution: 32, 40.3, and 50.8 line pairs/mm; DOF: 15, 10, and 6 mm) than the VS (resolution: 20.1 line pairs/mm; DOF: 5 mm). Accuracy testing showed the DOM produced better results than the VS for both resident and student groups (P Conclusions Considering the findings from this study, the DOM stands out as the leading magnification tool in endodontics. However, the VS has potential in endodontic procedures and might be used as an adjunct to other visualization aids.

Videoscope-assisted minimally invasive periodontal surgery for bone regeneration (VMIS)
Clinical Dentistry Reviewed, 2020Co-Authors: Stephen K. HarrelAbstract:Following the introduction of minimally invasive surgical techniques for treating periodontal defects, a novel visualization method was essential to allow for the use of smaller incisions and for a lingual access surgical approach. A Videoscope has been developed for use in minimally invasive periodontal surgery that facilitates visualization of the periodontal defect and permits access to the defect from the lingual aspect. The minimally invasive surgical technique developed to utilize the benefits of the Videoscope is known as Videoscope-assisted minimally invasive surgery (VMIS). This article reviews the technique for performing the VMIS procedure for periodontal lesions on natural teeth and for peri-implant lesions on implants.

Videoscope-Assisted Minimally Invasive Surgery (VMIS) for Bone Regeneration
Advances in Periodontal Surgery, 2019Co-Authors: Stephen K. HarrelAbstract:The concept and relevant literature related to minimally invasive periodontal surgery is reviewed. The original MIS procedure for bone regeneration is described as well as the modification of MIS for the MIST and M-MIST procedure. The development and introduction of the Videoscope for periodontal procedures are also reviewed. The Videoscope’s ability to visualize and treat periodontal defect through much smaller surgical openings than the MIS or MIST techniques has led to the development of the Videoscope-assisted minimally invasive surgery (VMIS) approach. The VMIS procedure is reviewed in detail. The results from long-term studies of the VMIS procedure are reported. A procedure for using the Videoscope and applying the concepts of VMIS to the problem of regenerating bone in instances of peri-implantitis is also presented. The use of small incisions that produce minimal trauma and preserve most of the blood supply of the periodontal and peri-implant tissues results in improved regenerative results, minimal to no negative esthetic outcomes, and little or no patient discomfort. Minimally invasive procedures are a reliable method to regenerate periodontal tissues.

Videoscope-Assisted Minimally Invasive Surgery (VMIS) for Bone Regeneration around Teeth and Implants: A Literature Review and Technique Update
Dentistry journal, 2018Co-Authors: Stephen K. HarrelAbstract:Background—The literature related to minimally invasive periodontal surgery is reviewed. This includes the original minimally invasive surgery (MIS) procedure for bone regeneration, the modification of MIS for the minimally invasive surgery technique (MIST) and modified MIST (M-MIST) procedures, and the introduction of the Videoscope for oral surgical procedures and the ability to perform Videoscope-assisted minimally invasive surgery (VMIS). The evolution from MIS through MIST to the current VMIS is reviewed. The results from studies of each of these methods are reported. Conclusion—The use of small incisions that produce minimal trauma and preserve most of the blood supply to the periodontal and peri-implant tissues results in improved regenerative outcomes, minimal to absent negative esthetic outcomes, and little or no patient discomfort. Minimally invasive procedures are a reliable method to regenerate periodontal tissues.
