RESUMEN
A 55 years lady presented with dull aching right upper abdominal pain with intermittent episodes of diarrhea following cholecystectomy which she underwent fourteen years back. Ultrasound and computed tomography findings were suggestive of foreign body in right subhepatic space. Exploratory laparotomy revealed circumvented loop of ileum with intra luminal mass sized 5 x 10 cm, resection anastomosis of the segment of ileum was performed. When opened it contained a surgical sponge with no external communication but an internal fistulous tract was present between the proximal and distal loops beyond the mass. Though intraluminal migration of retained surgical sponge has often been reported, complete intraluminal migration without features of obstruction or external opening is rarely seen.
