Objective To investigate the effect and clinical application of two kinds of endoscopic titanium clip in treatment of iatrogenic or iatrogenic perforation of duodenal descending part. Methods For 15 cases of perforation of duodenal descending part, according to the specific location of the perforation, select different endoscopic, compare the closing efficiency and success rate. Results 8 cases closed under gastroscopy in 15 cases of descending part of duodenum perforation, successfully closed in 7 cases, success rate was 87.5 %; 7 cases closed under duodenoscopy, successfully closed in 7 cases, the success rate 100.0%. 14 cases successfully closed by endoscopic titanium clip in 15 cases, 1 case failed, the success rate was 93.3 %. The effective titanium clip quantity, invalid (loss) titanium clip quantity and the closing time between the two groups has no statistically significance (P > 0.05). Conclusion It is safe and effective to use two kinds of endoscopic titanium clips in treatment of iatrogenic or iatrogenic duodenal per-foration.
