Pyloric stenosis or its total closure is found in approximately 2-4% of patients with peptic ulcer disease. The pathology usually occurs as a result of healing of an ulcer (gastric or duodenal bulb). Pyloric stenosis or closure leads to complete or partial obstruction of the gastrointestinal tract, which prevents the normal passage of food. Less common causes of pyloric stenosis include prolonged inflammation within the duodenal bulb and the pylorus, postoperative complications after surgical interventions inside the peritoneum within the bile ducts, duodenum and stomach, traumatic injury as a result of ingestion of a foreign body, and also because of cancer of the stomach, duodenum and pancreas. Extremely rare cases of pyloric stenosis are intestine or stomach entrapments in a ventral hernia sac. This article presents a rare case of stomach entrapment in the gate of a ventral hernia with subsequent obstruction of the pylorus. On the basis of the analyzed case it can be concluded that the surgical procedure is different than in a slowly progressing stenosis and in case of entrapment, it must be taken as a matter of urgency because of the possibility of necrosis in the wall of the stomach. The extent and type of surgery depend on the intraoperative assessment.
