Insights
Duodenal salami ulcer in children presents as inflammation or erosion, not a true ulcer, often linked to Helicobacter pylori infection. Treatment with antacids and antimicrobials leads to good outcomes.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Pathology
- Infectious Diseases
Context:
- Duodenal salami ulcer is an endoscopic finding in children, characterized by a unique mucosal appearance.
- Understanding its clinicopathological features is crucial for accurate diagnosis and management in pediatric patients.
Purpose:
- To explore the characteristics and clinicopathological features of duodenal salami ulcer in children.
- To deepen the understanding of the etiology and presentation of this condition.
Summary:
- Endoscopic findings revealed a hoarfrost-like coating on inflamed duodenal mucosa in 117 pediatric cases.
- Histopathology showed inflammation, erosion, and a high prevalence of Helicobacter pylori (Hp) infection in the gastric antrum (58%) and duodenal bulb (11.1%).
- Treatment with antacids and antimicrobial agents resulted in lesion healing without scarring.
Impact:
- Identifies duodenal salami ulcer as a manifestation of duodenal inflammation/erosion, not a true ulcer, in children.
- Highlights the significant role of Hp infection and increased gastric acid in its pathogenesis.
- Establishes effective therapeutic principles and a positive prognosis for pediatric patients.
Objective:
Duodenal salami ulcer is a common disease found on routine endoscopic examination in children. The purpose of the study was to explore the characteristics and the clinicopathological features of duodenal salami ulcer in children and to deepen the understanding of duodenal salami ulcer.
Methods:
The endoscopic results of 117 cases with the duodenal salami ulcer were analyzed. The specimens of gastric antrum and duodenal bulb were subjected to HE and Giemsa staining and were examined for any alteration in histopathology and infection with Helicobacter pylori (Hp). The duodenal mucosa was stained with AB (pH 2.5)/PAS in order to diagnose the duodenal metaplasia.
Results:
The major endoscopic finding was a kind of hoarfrost, which was dotty or flaky, covered on the hyperemic and edematous mucosa. The detection rate of this change was 2.29% (117/5 106) of all the endoscopic examinations in children and the rate among cases with duodenal ulcer was 49.2% (117/238). The histopathology was characterized by a heavy infiltration of mainly lymphocytes, plasmocytes and neutrophilic granulocytes, frequently accompanied by superficial erosion. Sixty-one cases were pathologically diagnosed as chronic active duodenitis, superficial erosion in 45; chronic duodenitis in 50; eosinophilic duodenitis in 6. Detection rate of Hp in gastric antrum was 58% (68/117) of all cases. Detection rate of Hp infection and gastric epithelium metaplasia in duodenal bulb was 11.1% (13/117) and 31.1% (37/117), respectively. However, detection rate of Hp in gastric antrum was 25.0% (1 203/4 810) in 4 810 cases of normal duodenal bulb and chronic duodenitis in the same period. Detection rate of Hp in duodenal bulb was 0% and the detection rate of gastric epithelium metaplasia in duodenal bulb was 2.7% (128/4 810). All these detection rates were much higher than those of the specimens collected during the same period with normal duodenal bulb and chronic duodenitis (P < 0.001). Twenty-one cases were reexamined by endoscopy after having been treated with antacids or antacids and antimicrobial agents for 4 weeks. The lesions were healed up and no scars were found.
Conclusion:
Duodenal salami ulcer in children had a special manifestation of duodenal inflammation or erosion but not a real ulcer. It was caused by the Hp infection in gastric antrum or duodenal bulb and the increase of gastric acids. The therapeutic principles were antacid and antimicrobial agents. The prognosis was good.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
