case_images: Radiological appearance of gossypiboma. (A) Retained surgical sponge extending from right colon into the transverse colon and up to descending colon (white arrows). (B, C) Abdominal computed tomography scan (axial section) showing gossypiboma within the large bowel loops (white arrows).

case_images: The CT scan further showed a 27-cm-long tubular calcified foreign body within the large bowel, extending from the hepatic flexure to the mid-descending colon with few linear internal lucencies, raising suspicion of a misplaced stent with encrustation or a chronically retained sponge (Figure 1).
case_images: Endoscopic view of gossypiboma. (A) Proximal end of retained surgical sponge anchored into the ascending colon mucosa. (B, C) Gossypiboma extending into the transverse colon and up to descending colon. (D) Anchoring point of gossypiboma after its successful resection and retrieval showing nodularity and erythema.

case_images: Subsequently, a colonoscopy was performed, which showed a foreign body with its proximal end embedded in the ascending colon (Figure 2) and distal end extending up to the descending colon (Figure 2). The surrounding mucosa at the proximal attachment site was nodular with a mild local inflammatory response (Figure 2).
case_images: 40-cm-long surgical sponge retrieved successfully.

case_images: The foreign body was grasped from its distal end with a snare and retrieved along the colonoscope, showing a 40-cm-long and 5-cm-wide retained sponge (Figure 3).
case_images: X-ray abdomen erect showing no signs of pneumoperitoneum after endoscopic removal of gossypiboma.
