Black oesophagus, upside-down stomach and cameron lesions: cascade effects of a large hiatal hernia

Acute oesophageal necrosis, black oesophagus (BE) or Gurvits syndrome (GS) is a rare form of severe oesophagitis appearing as a striking circumferential discolouration of distal mucosa with various proximal extensions abruptly terminating at the gastro-oesophageal junction. It is most commonly associated with acute exacerbations of medical comorbidities, while associations with altered gut anatomy are rare. We present a unique constellation of BE, Cameron ulcers (CU), and gastric volvulus from a large paraesophageal hiatal hernia. Our patient recently recovered from COVID-19 and was malnourished and frail, while the expanding paraesophageal hiatal hernia turned into an acute organoaxial gastric volvulus with accompanying outlet obstruction. In low-flow post-COVID coagulopathic states, compensatory mechanisms may lack against gastric stunning and sudden massive reflux on the oesophagus. We additionally performed a systematic review and discovered additional cases with coexistent volvulus and paraesophageal hernia, although there are no previous reports of BE with CU, which makes this study the first.

Esophageal Hiatal Hernia: A Possible Scintigraphic Feature

An 81-year-old woman with symptoms of upper Gastrointestinal (GI) obstruction but with no supporting evidence for obstruction in previous endoscopies was studied with a solid-liquid gastric emptying scintigraphic examination. There was evidence of accumulation of the tracer in a part of the stomach in the thorax before filling the stomach. The paraesophageal hiatal hernia was suspected. The diagnosis was not confirmed by other modalities and the patient passed away after upper GI bleeding a month later.

Type IV paraesophageal hiatal hernia and organoaxial gastric volvulus

Organoaxial gastric volvulus occurs when the stomach rotates on its longitudinal axis connecting the gastroesophageal junction to the pylorus. With that, the antrum of the stomach usually rotates in the opposite direction in rela-tion to its fundus (1). This phenomenon has often been known to be associated with diaphragmatic defects (2) Importantly, abnormal rotation of the stomach of more than 180° is a life threatening emergency that may create a closed loop ob- struction which may result in incarceration leading to strangulation, and hence, a surgical emergency. We present the case of a middle-aged female who presented with organoaxial gastric volvulus and had an associated Type IV paraesophageal hiatal hernia that was treated electively. Normally an emergent gastric volvulus is diagnosed via Borchardt’s classic triad (epigastric pain, unproductive vomiting and diffculty inserting a nasogastric tube); however in this patient the nasogastric tube (NGT) was passed into the antrum which allowed additional time for resusci-tation with fuids and other symptomatic relief.
