Description
Summary:Gastrinomas are the most common neuroendocrine tumors worldwide and cause a clinical syndrome known as Zollinger-Ellison Syndrome (ZES). Increased acid production resulting from elevated gastrin levels contributes to symptoms such as abdominal pain, heartburn, and diarrhea. However, the non-specificity and overlap in the symptoms with idiopathic peptic ulcer disease and gastroesophageal reflux disease (GERD) can lead to delayed diagnosis. In this case, we describe a patient with a past medical history of GERD and a perforated gastric ulcer who continued to experience symptoms of dyspepsia and had a subsequent esophageal perforation, despite H. pylori eradication and high-dose proton pump inhibitor (PPI) therapy. Multiple ulcers were visualized in the first portion of the duodenum, and metastatic lesions were demonstrable in the liver. Serum gastrin level was elevated to 433 pg/mL. Histology of liver biopsy showed a well-differentiated neuroendocrine tumor, supporting the diagnosis of ZES. This article underscores the significance of considering ZES in the differential in cases of refractory gastric hyperacidity and the importance of early diagnosis with serum gastrin testing to prevent complications such as gastric obstruction, perforation, hemorrhage, esophageal strictures, or rupture and to minimize the risk of metastasis. It is noteworthy that while perforations in cases of ZES typically occur in the duodenum, this particular case is atypical as it had involved the stomach. Furthermore, it was associated with esophageal perforation, likely resulting from forceful and prolonged vomiting caused by persistent dyspepsia.
