Colonoscopy with air insufflation is known to result in abdominal pain and discomfort.
Dr Jun and colleagues determined the effectiveness of water infusion during colonoscopy through a meta-analysis.
The team identified original papers and abstracts published up to 2011 in MEDLINE, EMBASE, Cochrane Library Database and important meeting abstracts.
Clinical appraisal and data extraction were conducted by 2 reviewers independently.
|Water infusion significantly decreases patient discomfort |
The team included 7 studies involving 872 patients.
The team of doctors showed that the water infusion group had fewer patients requiring abdominal compression or position change, a lower mean pain score, lower maximum pain score, and fewer patients requiring on-demand sedation than the air insufflation group during colonoscopy.
There were no significant differences in caecal intubation rate, cecal intubation time, total procedure time and adenoma detection rate.
Dr Jun's team commented, "Water infusion significantly decreases patient discomfort and abdominal pain during colonoscopy without affecting operation time and intubation success rate."
