Abstract:
Objective:To evaluate the safety, feasibility and operational effectiveness of master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ in upper gastrointestinal endoscopy examination in living pigs.
Methods:Seven Guangxi BA-MA Mini-pigs underwent upper gastrointestinal endoscopy examination with master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ and Olympus GIF-Q260J gastroendoscope (Japan). The experiment divided into manual operation group and robot operation group. Nine gastroenterologists skilled with endoscopy operation handled the robot once in vitro to familiar with the mechanism and method of robot operation. And then performed manual operation and robot operation four times each. Endoscopy pictures and operation time were recorded. T test and one-way analysis of variance were performed for statistical analysis.
Results:Both manual operation and robot operation could successfully finish standard esophagus and stomach endoscopic examination. There were no complications such as hemorrhage, perforation, mistaken insertion into of trachea, injures of pharynx and larynx and inhalation pneumonia. Esophagus, gastric cardia, gastric fundus, gastric body, gastric angle, gastric antrum and gastric pylorus could be clearly observed in both groups. The manual operating time of nine gastroenterologists was (3.67±1.95) minutes, which was shorter than that of robot operating time ((7.60±2.00) minutes), and the difference was statistically significant (t=8.445, P<0.01). The time of first in vitro operation performed by nine gastroenterologist was (13.10±6.32) minutes. The operation times of each case of nine gastrienterologist were (8.49±0.90) minutes, (7.50±1.19) minutes, (7.30±1.33) minutes and (7.12±1.61) minutes. The difference was statistically significant (F=7.901, P<0.01). Operation time gradually shortened and operation proficiency significantly improved.
Conclusion:Master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ which provides a clear observation of esophagus and stomach is safe in endoscopic examination of living animal.
