ScholarBank@NUS Repository. https://doi.org/10.1016/j.gie.2010.04.009 | Abstract: | Background: Performing endoscopic submucosal dissection (ESD) by using standard endoscopy platforms is technically challenging because of the equipment's lack of dexterity. Objective: To explore the feasibility of using the Master and Slave Transluminal Endoscopic Robot (MASTER), a novel robotics-enhanced endosurgical system, to perform ESD. Design: ESD was performed on simulated gastric lesions in 5 Erlangen porcine stomach models (ex vivo) and 5 live pigs (in vivo). Performance of ESD by using the MASTER was compared with that using the insulation-tipped (IT) diathermic knife. Setting: SMART Laboratory, Advance Surgical Training Centre, National University Hospital, Singapore. Subjects: Five Erlangen porcine stomach models and 5 pigs, 5 to 7 months old, each weighing about 35 kg. Interventions: ESD. Main Outcome Measurements: Lesion resection time, grasper and hook efficacy grade, completeness of resection, and presence of procedure-related perforation. Results: In the Erlangen stomach models, 15 simulated lesions from the cardia, antrum, and body were removed en bloc (mean dimension, 37.4 × 26.5 mm) by electrocautery excision using the MASTER. The mean ESD time was 23.9 minutes (range 7-48 minutes). There was no difference in the dissection times of lesions at different locations (P = .449). In the live pigs, the MASTER took a mean of 16.2 minutes (range 3-29 minutes) to complete the ESD of 5 gastric lesions, whereas the IT diathermic knife took 18.6 minutes (range 9-34 minutes). There was no significant difference in the times taken (P = .708). All lesions were excised en bloc; the mean dimensions of lesions resected by the MASTER and the IT diathermic knife were 37.2 × 30.1 mm and 32.78 × 25.6 mm, respectively. The MASTER exhibited good grasping and cutting efficiency throughout. Surgical maneuvers were achieved with ease and precision. There was no incidence of excessive bleeding or stomach wall perforation. Limitations: Exploratory study with limited sample size. Conclusions: Performing ESD by using the MASTER is feasible. © 2010 American Society for Gastrointestinal Endoscopy. | Source Title: | Gastrointestinal Endoscopy | URI: | http://scholarbank.nus.edu.sg/handle/10635/113459 | ISSN: | 00165107 | DOI: | 10.1016/j.gie.2010.04.009 |
