L
ittle benefit for repeat colonoscopy
within 10 years in patients with
no polyps on initial exam
Repeat colonoscopies within 10
years are of little benefit to
patients who had no polyps found on
adequate examination; however, repeat
colonoscopies do benefit patients when the
baseline examination was compromised,
according to research published in the
August issue of Gastroenterology.
David A. Lieberman, M.D., of the Oregon
baseline examination, the incidence of large
polyps upon repeat colonoscopy was 3.1
percent (95 percent CI, 2.7 to 3.5 percent) within
one to five years and 3.7 percent (95 percent CI,
3.3 to 4.1 percent) within five to 10 years.
"In light of the maturing body of evidence
about the strong influence of sex, race/
ethnicity, and other factors (e.g., tobacco,
alcohol, diet) on the risk of neoplasia,
individualized risk-based screening and
surveillance algorithms should be developed,"
write the authors of an accompanying editorial.
The practice network has received
funding from pharmaceutical and
biomedical companies.

Anticoagulant Varies by Surgery
Aspirin may be less preferable to
other anticoagulants following hip
fracture repair, but may be favored
after elective knee or hip arthroplasty,
according to a meta-analysis published online
July 17 in the Journal of Hospital Medicine.
Frank S. Drescher, M.D., from the Geisel
School of Medicine at Dartmouth in White
River Junction, Vt., and colleagues conducted
a systematic literature review to identify
randomized trials comparing aspirin to
anticoagulants for prevention of venous
thromboembolism (VTE) following major
lower extremity orthopedic surgery.
The researchers identified eight trials (1,408
participants) that met inclusion criteria. Deep
venous thrombosis rates did not differ statistically
between aspirin and anticoagulants (relative risk
[RR], 1.15; 95 percent confidence interval [CI], 0.68
to 1.96). There was a nonsignificant trend favoring
anticoagulation following hip fracture repair (RR,
Health and Science University in Portland, and
colleagues analyzed data for 17,525
asymptomatic patients who were found to
have no polyps during a screening
colonoscopy and received another
colonoscopy within 10 years.
The researchers found that repeat
