Application of rotary biopsy forceps in diagnosis of gastric pre-cancerous lesions / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the sampling efficiency of rotary biopsy forceps in gastric precancerous lesions. Methods A total of 60 gastric lesions with suspected pre-cancerous characters under narrow band imaging were enrolled,and consecutive samples were taken from same lesion by one endoscopist with routine and rotary forceps,respectively. The most severe pathological diagnosis was regarded as the final diagnosis. Results There was a significant difference between rotary biopsy forceps and routine ones in regarding of sample quality and capability of minimize tissue damage (P＜0. 05). The concordance rate with final pathological diagnosis from sample taken by rotary biopsy forceps was higher than that from routine ones,but without significance (P＞0. 05). Conclusion The rotary biopsy forceps is superior to routine ones in sampling of gastric pre-cancerous lesions.
