Insulating and cooling effects of nasal Endoscope Sheaths and irrigation.
International forum of allergy & rhinology, 2014Co-Authors: John P. Craig, Parul GoyalAbstract:Background Heat generated at the tips of nasal Endoscopes have been shown to reach temperatures high enough to cause thermal tissue injury. Endoscope Sheaths have the potential to minimize the risk of thermal tissue injury. The purpose of this study was to assess the abilities of plastic and metal Endoscope Sheaths and Sheath irrigation to insulate against dangerous scope tip temperatures. Methods A 4-mm 0-degree rigid nasal Endoscope was used with light-emitting diode (LED) and xenon light sources (400-W LED, 300-W, and 175-W xenon) to assess scope tip temperature before and after Endoscope Sheath placement. Temperatures were assessed again after placement of each Sheath, both before and after active saline irrigation. Scope tip temperature was measured using a noncontact infrared thermometer. Results The unSheathed rigid scope tip reached a maximal temperature after 10 minutes at 100% light source intensity. The 400-W LED and 300-W xenon sources generated potentially dangerous scope tip temperatures exceeding 42°C, whereas the 175-W xenon source never generated a maximal temperature over 32.6°C. After placement of plastic and metal Sheaths, mean scope tip temperatures were decreased by 2°C (4.8%) and 2.2°C (5.5%), respectively. After active saline irrigation, mean scope tip temperatures were decreased by 5.1°C (12.6%) and 5.2°C (12.8%), respectively. Conclusion With modern light sources, nasal Endoscopes have the potential to reach temperatures that may cause thermal tissue injury. Endoscope Sheaths lead to decreases in scope temperatures, and the effect is greater with active irrigation. In addition to improving visualization, Endoscope Sheaths may decrease the risk of thermal tissue injury.

Real-time ultrasound-guided endoscopic surgery for putaminal hemorrhage.
Journal of neurosurgery, 2015Co-Authors: Hirokazu Sadahiro, Sadahiro Nomura, Hisaharu Goto, Kazutaka Sugimoto, Akinori Inamura, Yuichi Fujiyama, Akiko Yamane, Takayuki Oku, Mizuya Shinoyama, Michiyasu SuzukiAbstract:OBJECT Endoscopic surgery plays a significant role in the treatment of intracerebral hemorrhage. However, the residual hematoma cannot be measured intraoperatively from the endoscopic view, and it is difficult to determine the precise location of the Endoscope within the hematoma cavity. The authors attempted to develop real-time ultrasound-guided endoscopic surgery using a bur-hole-type probe. METHODS From November 2012 to March 2014, patients with hypertensive putaminal hemorrhage who underwent endoscopic hematoma removal were enrolled in this study. Real-time ultrasound guidance was performed with a bur-hole-type probe that was advanced via a second bur hole, which was placed in the temporal region. Ultrasound was used to guide insertion of the Endoscope Sheath as well as to provide information regarding the location of the hematoma during surgical evacuation. Finally, the cavity was irrigated with artificial cerebrospinal fluid and was observed as a low-echoic space, which facilitated detection of res...

3D-printed model-guided endoscopic evacuation for basal ganglia hemorrhage.
Scientific Reports, 2020Co-Authors: Jun Zhang, Hongyu Cheng, Sitong Zhou, Lijin Huang, Peng Wang, Jiajing Chen, Tongxin Jin, Guiyong ZhengAbstract:The purpose of this study was to investigate the effectiveness and practicality of 3D-printed model-guided endoscopic surgery for the treatment of basal ganglia hemorrhage. The authors retrospectively analyzed the data of all patients who underwent endoscopic evacuation of basal ganglia hemorrhage in the Department of Neurosurgery at Dalang Hospital and Shipai Hospital between December 2017 and February 2019. Twelve patients, in whom the 3D-printed model guidance was used for endoscopic evacuation, were included in this investigation. Using 3D reconstructed technology, we designed the appropriate surgical approach. Then, an individualized facial model with the guide orifice was printed by a 3D printer. Further, the 3D-printed model was employed to guide the insertion of the Endoscope Sheath. As a result, the average evacuation rate was 97.2% (range 90.1-100.0%). The GCS and mRS score were improved in each patient from admission to discharge examination. All patients had a good prognosis based on their functional independence measure (FIM) scores at the 6-month follow-up. The 3D-printed model-guided endoscopic evacuation was effective and safe for basal ganglia hemorrhage. This technique deserves further investigation to determine its role in intracerebral hemorrhage management.
