[edit] Discussion of Bouveret syndrome

  • Bouveret syndrome is a gastric outlet obstruction produced by a gallstone impacted in the distal stomach or proximal duodenum.
  • Occurs most commonly in elderly women with a mean age of 69 years.
  • The presenting clinical situation is variable and nonspecific but often includes nausea, vomiting, and epigastric pain.
  • Early diagnosis is important because mortality is historically high at 33%, although it has decreased to 12% in recent years.

  • Endoscopy is preferred as a therapeutic option because removal may be performed with mechanical, electrohydraulic, or laser lithotripsy.
  • Surgery often is not desirable as the patients are often poor surgical candidates secondary to concomitant illnesses and advanced age.
