There have been numerous case reports and discussions of jejunogastric intussusception following gastroenterostomy since the first mention by Bozzi11 in 1914. However, it is not so well known that jejunogastric intussusception may occur after subtotal gastrectomy. Lundberg32 was apparently the first to report such a case in 1922. A review of essential features of 28 cases reported by 25 authors through 1958 strongly suggests that unfamiliarity with this rare complication of gastrectomy was the cause of delay in instituting proper therapy in many instances. Several references to retrograde jejunogastric intussusception after gastrectomy were not available to us but are appended for the sake of completeness.*
