Not just an upset stomach: gastric perforation in a patient with anorexia nervosa

Gastric perforation in patients with anorexia nervosa is a rare entity associated with high morbidity and mortality [Norris in Int J Eat Disord 49:216-237, 2016]. In cases reported in the literature, the perforation was often preceded by a binge episode, and the subsequent clinical presentation was rapid and acutely deteriorating with a fatality rate as high as 80% [Norris in Int J Eat Disord 49:216-237, 2016, Pitre in J Med Case Rep 15:61, 2021]. We present a case of gastric perforation in the context of restrictive anorexia nervosa unique both for the absence of a premorbid binge episode as well as delayed clinical manifestations of medical distress, leading to abdominal compartment syndrome.Level IV Evidence obtained from multiple time series analysis such as case studies.
