Cc. Yang et al., THE NATURAL-HISTORY (FADING TIME) OF STIGMATA OF RECENT HEMORRHAGE INPEPTIC-ULCER DISEASE, Gastrointestinal endoscopy, 40(5), 1994, pp. 562-566
From October 1991 to December 1992, 144 patients with bleeding peptic
ulcer and stigmata of recent hemorrhage were included in a study desig
ned to investigate, by means of endoscopic examinations repeated at 2-
day intervals, the evolutionary development of stigmata of recent hemo
rrhage, such as visible vessels, and to determine the time required fo
r each type of stigma to fade. Eighty-five patients underwent endoscop
ic follow-up until the stigmata had disappeared. A visible vessel take
s about 4.1 +/- 2.1 days to disappear, requiring significantly more ti
me than an adherent clot or an old stigma, which take 2.4 +/- 0.8 days
and 2.4 +/- 1.3 days, respectively (p < .05). Bleeding does not recur
after stigmata disappear. Time required for stigmata to fade is not a
ffected by age, sex, smoking, history of peptic ulcer, ulcer location,
severe bleeding, underlying systemic disease, or endoscopic local the
rapy. While healing, stigmata of recent hemorrhage evolve through a se
quence of phases: a visible vessel may or may not appear as an adheren
t clot and then as a red or black flat spot before disappearing.
