Article Abstract
Introduction: Gastric heterotopia rarely occurs in the small intestine beyond ligament of Treitz. Most cases of jejunal gastric heterotopia have been reported in children and young adults. Herein we report a case of jejunal gastric heterotopia presenting as a perforation peritonitis in a middle-aged adult.
Presentation Of Case: A 51-year-old male presented with abrupt onset abdominal pain of 1 day duration. Physical examination revealed abdominal tenderness and rebound tenderness as well as costovertebral angle tenderness. Abdominal computed tomography revealed pneumoperitoneum, suggestive of hollow viscus perforation. At emergency laparotomy, a perforation site was discovered in the jejunum 100 cm distal to the ligament of Treitz. On macroscopic examination, the mucosa contained a 3 × 4 cm ill-defined, shallow ulceration next to the perforation site. Microscopically, the mucosa surrounding the perforation site revealed gastric heterotopia which consisted of gastric foveolar epithelium along with abundant pyloric glands and a few fundic glands.
Discussion: To the best of our knowledge, this case is the presumed oldest jejunal gastric heterotopia patient presenting with perforation peritonitis ever reported.
Conclusion: Jejunal gastric heterotopia should also be considered in the differential diagnosis of perforation peritonitis in adults.

Background: The clinical course and manifestations of subepithelial lesions (SEL) patients tend to vary from different pathological types, therefore the accurate diagnosis of SEL would undoubtedly be beneficial to the treatment and prognosis of SEL patients. Based on the decision tree method, we developed a novel classification model for SELs by combining endoscopy with endoscopic ultrasound (EUS).
Methods: We retrospectively collected data from 469 patients hospitalized in the Affiliated Hospital of Qingdao University between January 2017 to November 2021 for endoscopic resection.

Inlet patch (IP) is a congenital anomaly characterized by gastric heterotopia in the cervical esophagus. While extensively described in adults, it remains poorl characterized in pediatric populations. This retrospective, single-center study included all pediatric patients (0-14 years) diagnosed with IP between 2018 and 2025.

Gastric duplication cysts (GDCs) are rare congenital anomalies of the gastrointestinal tract that can present with nonspecific symptoms, leading to diagnostic challenges and potential complications. We report the case of a four-month-old female infant who presented with persistent nonbilious vomiting, failure to thrive, and abdominal distension. Imaging (abdominal ultrasound and CT scan) revealed a bilobed intra-peritoneal cystic mass, consistent with a GDC.
