Journal of Forensic and Crime StudiesGastric perforation, in neonates, is a rare complication, but with high morbidity. Generally, the diagnosis is made, in vivo, in premature, low-weight children, with or without several risk factors, such as the use of mechanical ventilation, gastric tube placement, and gastrointestinal abnormalities, such as esophageal atresia, duodenal membranes, poor rotation intestinal necrotizing enterocolitis. There is no consensus as to how idiopathic forms of gastric perforation are also adventurous histologically in the musculature of the gastric wall. We presented a surveillance case, which was referred to the IML-DF for cadaveric examination, with suspicion of sudden death. During the examination, generalized peritonitis and perforation of great curvature of the stomach were identified, without other gastrointestinal activities.
