It arises as a result of the introduction of the adducting segment of the intestine into the abducting one. Gastroduodenal intussusception is an extremely rare type of high intestinal obstruction. It most often occurs after surgery on the stomach and much less often in non-operated patients. Intussusception of the jejunum into the stomach can occur soon after surgery, but most often, this complication occurs 515 years after the intervention. This paper describes a case of retrograde intussusception that arose 9 years after the Billroth II gastric resection with Braun anastomosis. This clinical case acquaints specialists with the possibility to encounter this pathology in clinical practice and demonstrates the appropriateness of differential diagnostics in cases with similar clinical symptoms.</p>gastric cancerintussusceptiongastroenteroanastomosisgastric resectioncancer recurrenceрак желудкаинвагинациягастроэнтероанастомозрезекция желудкарецидив рака[Kazushhik V.L., Protasevich A.I.
