Effect of the modified endoscopic operation instrument hanger in endoscopic surgery

Abstract

Objective To explore the effect of the modified endoscopic operation instrument hanger on the cooperating operation. Methods A total of 50 patients with endoscopic submucosal dissection (ESD) from January 2014 to June 2015 were selected as the research object and they were randomly divided into observation group and control group by random number table method, with 25 cases in each group. Ordinary endoscopic operation instrument operating table was used in the control group, while the modified endoscopic operation instrument hanger was used in the observation group in order to lay a sterile operating table. Both the contamination rate and the error fetch rate were observed in the same circumstance, including the partner, endoscopist and operation mode. The contamination was defined as surgical instruments touched the other place. Results In control group, the error fetch rate was 16.72% (96/574) , the contamination rate was 11.85% (68/574) and the average operation time was (76.40±2.59) min. While the error fetch rate, contamination rate and average operation time for the observation group were 1.02% (6/584) , 0.86% (5/584) and (51.80±2.08) min, respectively. The differences were significant (P<0.05) . Conclusions The application of modified endoscopic operation instrument hanger can decrease the probability of fetch errors and the rate of surgical instruments contamination. The present modification has obvious innovation and practicality, which worthy to be widely popularized in clinical.
