Current application situation of gastrointestinal endoscopy in China

AIM:To study the current application situation of gastrointestinal(GI) endoscopy in China’s mainland.METHODS:From 12 August,2011 to 15 February,2012,draft questionnaires were sent by e-mail to 289 hospital-based GI endoscopy units,including units with three levels(provincial,prefecture and county level) in China’s mainland.All the surveyed GI endoscopy units were state-owned and hospital-based.Proportions were compared using χ 2 tests.Comparisons between groups were performed using the Mann-Whitney U test.A probability of P < 0.05 was considered to represent a statistically significant difference.RESULTS:Based on satisfactory replies,169/279(60.6%) of units were enrolled in the survey,which covered 28 provinces(90.3%,28/31) in China’s mainland.Compared with published survey data,the number of GI endoscopes per unit has increased by nearly three times(from 2.9 to 9.3) in the past decade.About 33 of 169(19.5%) endoscopy units possessed an X-ray machine,which was mainly owned by provincial endoscopy units(43.2%,19/44).Video capsule endoscopes,which were almost unavailable ten years ago,were owned by 20.7%(35/169) of GI endoscopy units.Endoscopic submucosal dissection could be performed by 36.4%(19/44) of the provincial units,which was significantly higher than the prefecture level(9.9%,P < 0.01) and county level(0.0%,P < 0.01) units,respectively.CONCLUSION:Rapid development in GI endoscopy has been made in China’s mainland,and major diagnostic endoscopes and therapeutic endoscopy procedures are predominantly used in large endoscopy units.
