Endoscopic hemostasis is rarely used for hematochezia: a population-based study from the Clinical Outcomes Research...

Data on the use of endoscopic hemostasis performed during colonoscopy for hematochezia are primarily derived from expert opinion and case series from tertiary care settings.

To characterize patients with hematochezia who underwent in-patient colonoscopy and compare those who did and did not receive endoscopic hemostasis.

Retrospective analysis.

Demographics, comorbidities, practice setting, adverse events, and colonoscopy procedural characteristics and findings.

We identified 3151 persons who underwent in-patient colonoscopy for hematochezia. Endoscopic hemostasis was performed in 144 patients (4.6%). Of those who received endoscopic hemostasis, the majority were male (60.3%), white (83.3%), and older (mean age 70.9 ± 12.3 years); had a low-risk American Society of Anesthesiologists classification (53.9%); and underwent colonoscopy in a community setting (67.4%). The hemostasis-receiving cohort was significantly more likely to be white (83.3% vs 71.0%, P = .02), have more comorbidities (classes 3 and 4, 46.2% vs 36.0%, P = .04), and have the cecum reached (95.8% vs 87.7%, P = .003). Those receiving hemostasis were significantly more likely to have an endoscopic diagnosis of arteriovenous malformations (32.6% vs 2.6%, P = .0001) or a solitary ulcer (8.3% vs 2.1%, P < .0001).

Retrospective database analysis.

Less than 5% of persons presenting with hematochezia and undergoing inpatient colonoscopy received endoscopic hemostasis. These findings differ from published tertiary care setting data. These data provide new insights into in-patient colonoscopy performed primarily in a community practice setting for patients with hematochezia.
