Duodenal ulcer perforation is uncommon in children which is why it is not usually considered in the differential diagnosis of acute abdomen in them. In this brief report, we are presenting a case of successfully managed perforated duodenal ulcer in a child. Another interesting point was the presence of air only under right hemidiaphragm, a sign generally known to be associated with duodenal perforation.

| Introduction|| |
Duodenal ulcer is an infrequently diagnosed disease in children. , Being rare and, moreovered, due to a low index of suspicion on the part of physicians, it usually presents with serious complications such as perforation or gastrointestinal bleeding.  Perforated appendicitis is usually considered to be the most likely cause of acute abdomen than the involvement of a more proximal portion of gut (duodenum) in an otherwise healthy child.
Here, we are reporting a case who presented in emergency with features of acute abdomen. X-ray showed localized free air under right dome of the diaphragm. On exploration, surprisingly, duodenal perforation was found which was repaired successfully.
| Case Report|| |
A 3-year-old male child presented to pediatric surgical emergency with a history of fever, pain in abdomen, distension of abdomen, and no passage of stool for 2 days. The child had a history of analgesic and antipyretic intake for a week before presentation but none of hematemesis or malena. On physical examination, the child was lethargic, dehydrated, and had tachycardia and tachypnea. Cardiac examination was within normal limits. Chest examination revealed right-sided decreased air entry. The abdomen was distended, tender, and demonstrated generalized guarding with rebound tenderness. Liver dullness was masked, and bowel sounds were absent. Upright chest and abdominal radiograph showed the presence of localized free air under right dome of the diaphragm associated with right moderate pleural effusion [Figure 1]. After initial fluid resuscitation and intercostal chest tube drainage insertion that drained 100 ml of serous fluid, the child was taken up for emergency laparotomy with a provisional diagnosis of hollow viscus perforation peritonitis. At surgery, 8 mm × 4 mm perforation was seen on the anterior wall of the first part of duodenum [Figure 2] with moderate peritoneal contamination in the neighboring region. Stomach and pyloric region were unremarkable. Rest of the viscera were normal. Simple closure with omental patch (Graham's) followed by peritoneal lavage was performed, and the abdomen was closed with drain in the subhepatic space. The initial postoperative period was quite critical due to poor chest condition requiring the Intensive Care Unit care; however, subsequent recovery was uneventful. The patient was discharged on the 10 th day. Histopathology of ulcer margins revealed ulceration with chronic inflammation with eosinophils. On 2-month follow-up, the patient is well, and contrast study shows well-healed duodenum with no stricture [Figure 3].

| Discussion|| |
Duodenal ulcer disease does not usually present in pediatric surgical practice unless complicated by bleeding or perforation.  Its exact incidence and pathogenesis are debatable though one Indian series had reported the incidence as 1.55 cases per year.  Risk factors for peptic ulcer disease in children are similar to those in adults: Helicobacter pylori infection (the most common cause), Zollinger-Ellison syndrome, sickle cell anemia, blood group "O" or secondary to medications (such as nonsteroidal anti-inflammatory drug [NSAID]), and corticosteroids or physiological stress (burns, head injury, and mucosal ischemia).  In children (<10 year of age), duodenal ulcers secondary to NSAIDS predominate in comparison to those with H. pylori infection due to the frequent use of this.  Our patient had "O" blood group as well as NSAID intake due to febrile illness and both of these are well recognized predisposing factors for the entity.
One noteworthy point in this patient was the presence of air under right hemidiaphragm only while left hemidiaphragm was clear of it. Such sign is seen in few instances, of which duodenal perforation is frequently cited. 
The other conditions frequently found to be particularly associated with air under right hemidiaphragm are right subphrenic abscess and Chiladiti syndrome; the latter found very rarely among children. In our patient, the clinical history and sign were in agreement to the possibility of perforated duodenal ulcer, and it was confirmed per-operatively.
Various surgical procedures are described to deal with duodenal perforation, and these include simple closure with omental patch, truncal vagotomy and drainage procedure and hemigastrectomy. ,, Simple closure of perforation with omental patch with care not to obstruct the duodenal lumen is commonly performed in emergency settings as was done by us too.
Recurrence is rarely reported in children, thereby obviating the need of vagotomy. Another reason is that vagotomy is seen to be associated with more gastrointestinal dysfunction in children than in adults which should be taken care of. 
To summarize, acute duodenal ulcer perforation is a rare surgical emergency in pediatric practice, requiring a high index of suspicion to diagnose it and simple closure to surgically treat it.
