Immediate unprepared hydroflush colonoscopy for severe lower GI bleeding: a feasibility study
Gastrointestinal Endoscopy, 06/12/2012
Repaka A et al. – Immediate unprepared hydroflush colonoscopy in patients with severe lower GI bleeding is feasible with the hydroflush technique.Methods
- Primary outcome measurement was the percentage of colonoscopies in which the preparation permitted satisfactory evaluation of the entire length of the colon suspected to contain the source of bleeding.
- Secondary outcome measurements were visualization of a definite source of bleeding, length of hospital and intensive care unit (ICU) stays, rebleeding rates, and transfusion requirements.
- Thirteen procedures were performed in 12 patients.
- Complete colonoscopy to the cecum was performed in 9 of 13 patients (69.2%).
- However, endoscopic visualization was thought to be adequate for definitive or presumptive identification of the source of bleeding in all procedures, with no colonoscopy repeated because of inadequate preparation.
- A definite source of bleeding was identified in 5 of 13 procedures (38.5%).
- The median length of ICU stay was 1.5 days; of hospital stay, 4.3 days.
- Recurrent bleeding during the same hospitalization, requiring repeated endoscopy, surgery, or angiotherapy, was seen in 3 of 12 patients (25%).
