Abstract:
Objective To design a kind of suitable equipment to collect the specimens from endoscopic mucosal resection (EMR),and observe the effect of the collector on clinical application. Methods The six-hole rotating collector was made from transparent glass,in which the specimens could be aspirated through the channel and remained in a mental net. A total of 813 cases with 1254 lesions in esophagus,stomach and large intestine were included in the study. All the cases were male 516,female 297,age in 7-90 years old (average 53.2 years). The collector was used for receiving these EMR specimens that less than 1cm in diameter. The final diagnoses were proved by histopathologic examination. Results The rotating collector was named as Transparent 6-hole Rotating Eodoscopic Specimen Collector,and registered as national patent. The collector was a round column type,about 160g in weight and 56 mm?60 mm in size,which was light,clear and easily cleaned,and worked well during clinical application. The total collecting success rate for specimen receiving is 93.3%. All the specimen samples kept undamaged and good for histological analysis. Conclusion The rotating specimen collector is useful and economic for endoscopic mucosal resection.
