A gastric diverticulum is a rare disease, occurring in 0.04% of cases on contrast X-rays and 0.01-0.11% of cases of upper GI tract endoscopies. Diagnosis is often difficult due to non-specific symptoms, such as a feeling of fullness in the epigastrium after eating, dyspepsia, nausea and vomiting. In the case of symptomatic diverticulum, surgical treatment is indicated, where a priority is given to laparoscopic interventions. In the article, we present a case of a gastric diverticulum in a 37-year-old woman who was successfully operated laparoscopically.
