ABSTRACT Here, we present a case of gastric outlet obstruction due to focal nodular hyperplasia of the liver.
A 23-year-old female presented to our emergency clinic with nausea, vomiting, and abdominal pain. Endoscopy showed that the prepyloric region of the stomach was externally compressed by a lesion. Computed tomography and magnetic resonance imaging revealed a 70mm solid mass originating from the liver, extending caudally in an exophytic manner, and compressing the stomach. Laparotomy revealed an irregular and exophytic mass originating from the liver, which caused gastric outlet obstruction. The mass was resected with a 10mm safety margin. The histopathology report of the mass returned as focal nodular hyperplasia.
Gastric outlet obstruction is a clinical syndrome characterized by abdominal pain, nausea, and postprandial vomiting. This clinical condition frequently develops as a result of peptic ulcer disease, pyloric stenosis, and obstruction of pylorus by foreign bodies including phytobezoars, congenital duodenal webs, malignant disorders, and various lesions externally compressing the stomach. Gastric outlet obstruction due to hepatic lesions is extremely rare; few cases have been reported.
This is the first reported case of gastric outlet obstruction that developed due to focal nodular hyperplasia of the liver.
