We describe a case of perforated peptic ulcer (PPU) in a 9-month-old boy. A
bdominal distension was the first clinical sign of PPU. Before he developed
abdominal distension, the patient had suffered from an upper respiratory t
ract infection with fever for about 2 weeks, which was treated intermittent
ly with ibuprofen. A plain abdominal radiograph revealed pneumoperitoneum w
ith a football sign. At laparotomy, a 0.8-cm perforated hole was found over
the prepyloric area. Simple closure with omental patching was performed af
ter debridement of the perforation. Pathologic examination showed chronic p
eptic ulcer with Helicobacter pylori infection. The postoperative course an
d outcome were satisfactory. The stress of underlying disease, use of ibupr
ofen, blood type (A), and H, pylori infection might have contributed to the
development of PPU in this patient. PPU in infancy is rare and has a high
mortality rate; early recognition and prompt surgical intervention are key
to successful management.
