Perforated gastric ulcer is a particularly rare cause of peritonitis in children. Only few cases have been reported in the literature. It is a serious emergency condition which can be overlooked leading to life-threatening consequences. We report a case of a 12-year-old girl who presented with acute abdominal pain and signs of peritonitis. Surgical exploration found a gastric perforation on the anterior side of the antrum. Primary repair of the perforation was performed after thorough decontamination and taking biopsies from its edges. The post-operative period was uneventful. Helicobacter pylori test was negative. Histopathology result was suggestive of ulceration in the gastric wall and did not isolate H. pylori . Gastro-duodenal ulcer perforation should be considered in the differential diagnosis of children presenting with acute abdomen, especially when imaging showing pneumoperitoneum.

Annular pancreas (AP) is a congenital anomaly and a recognised cause of duodenal obstruction which can affect all age groups. It may manifest early in the neonatal period, but it may also have varied and often delayed symptoms. We report the case of AP in an 18-month-old girl with a long history of recurrent post-prandial non-bilious vomiting treated for a long time with the clinical diagnosis of gastroesophageal reflux. Upper gastrointestinal study was suggestive of partial duodenal obstruction and computed tomography revealed a complete ring of pancreatic parenchyma surrounding the second part of the duodenum. Diamond-shaped duodenoduodenostomy was achieved successfully and the post-operative period was uneventful. Although rare, AP must be kept in mind of any paediatric surgeon while confronted to symptoms of partial duodenal obstruction.
