The role of endoscopy in the patient with lower GI bleeding
Nov 14, 2016, 20:26 PM
Lower GI bleeding (LGIB) is diagnosed in 20% to 30%
of all patients presenting with major GI bleeding.4-6 The
annual incidence of LGIB is 0.03%, and it increases 200-
fold from the second to eighth decades of life.7-9 The
mean age at presentation ranges from 63 to 77 years.9,10
Approximately 35.7 per 100,000 adults in the United States
are hospitalized for LGIB annually, and a full-time gastroenterologist
manages more than 10 cases per year.8,11,12
Although blood loss from LGIB can range from trivial to
massive and life-threatening, the majority of patients have
self-limited bleeding and an uncomplicated hospitalization.
Compared with acute upper GI bleeding (UGIB), patients
with LGIB tend to present with a higher hemoglobin level
and are less likely to develop hypotensive shock or require
blood transfusions.6,13 The mortality rate ranges from 2%
to 4%8,10,14 and usually results from comorbidities and
nosocomial infections.15 A recent epidemiologic study reported
a decreased incidence of LGIB (41.8/100,000 in
2001 vs 35.7/100,000 in 2009; P Z .02) and a lower ageadjusted
and sex-adjusted case fatality rate (1.93% in
2001 vs 1.47% in 2009; P Z .003) over the past decade.
