ABSTRACT

OBJECTIVE@#To assess the safety and efficacy of carbon dioxide (CO(2)) in colonoscopy examination.@*METHODS@#We randomized 349 patients to undergo colonoscopy with insufflation of air (n=175) or CO(2) (n=174). At colonoscopy, p (ET CO(2)) was observed at 4 time points: before the exam, arrived caecum, back rectum, and after the exam. Patient's experience of pain in the end and after the examination at 1, 3, 6, and 24 h was registered using a visual analog scale (VAS). Sedation was not used routinely.@*RESULTS@#The groups were similar in age, sex, inspection time, and caecal intubation rate (all P>0.05). There were no significant differences in p (ET CO(2)) values between the 2 groups before and after the procedure (all P>0.05). VAS scores in the CO(2) group at various time points after the examination were significantly lower than those in the air group (all P<0.05). The percent of VAS scores of 0 in the CO(2) group after 1, 3, 6, and 24 h was significantly higher than that in the air group (all P<0.01).@*CONCLUSION@#Injection of CO(2) for colonoscopy will not cause CO(2) retention, and it may significantly reduce the pain, which is safe and effective.

ABSTRACT

OBJECTIVE@#To compare the hemostatic efficacy and safety of endoscopic band ligation(EBL) and endoscopic hemoclip placement(EHP) for bleeding due to Dieulafoy lesions in the upper gastrointestinal tract.@*METHODS@#Between February 2004 and October 2006, 34 patients with Dieulafoy lesions in the upper gastrointestinal tract were prospectively enrolled,including 22 cases of lesions in the stomach,10 in gastrointestinal stoma,and 2 in duodenal, who were randomly assigned to undergo EBL (n=16) or EHP (n=18). The therapeutic results of these 2 groups were compared.@*RESULTS@#The median number of O-ring or hemoclip required in the EBL group and the EHP group was similar. The rate of primary haemostasis,recurrent bleeding,transfer into surgery, complications, and average stay and blood transfusion requirements did not significantly differ in the 2 groups (P>0.05).@*CONCLUSION@#In this study, no significant differences are detected in the efficacy and the safety of EBL vs. EHP for bleeding due to Dieulafoy lesions in the upper gastrointestinal tract.
