Juvenile polyp in Thai
children--clinical and colonoscopic presentation.World
J Surg. 2007 Feb;31(2):395-8.
BACKGROUND: The
aim of this prospective study was to describe the clinical
characteristics of colorectal polyp in Thai children. METHODS: From
December 2002 to February 2005, children under 15 years of age
presenting with rectal bleeding were prospectively enrolled.
Demographic, clinical, and laboratory information was recorded.
Location, number, characteristics, and histopathology of the polyps
were noted. RESULTS: There were 32 patients with a mean age of 6.5
years. The most common presenting symptom was hematochezia, followed
by prolapsing rectal mass and diarrhea. In 20 patients there was a
single polyp, 6 had 2-4 polyps, and 6 were diagnosed with polyposis
coli. Most of the polyps were located exclusively at the rectum and
sigmoid colon. In only 7 cases were the polyps proximal to the
rectosigmoid region. This included 6 patients who had polyps beyond
the splenic flexure. All were juvenile polyps without evidence of
adenomatous changes. Compared to those with isolated polyps, the
patients with polyposis coli had a statistically significant incidence
of right-sided polyps (P <0.001) and a history of prolapse of the
rectal mass (P = 0.006). CONCLUSIONS: Because of the high prevalence
of right-sided polyps and the concern about malignant transformation,
colonoscopy should be considered as the initial evaluation in children
with rectal bleeding. |
