The adequacy of the field of view should also be evaluated, with particular attention to partially imaged sponges at the periphery of the image (Fig. The vagina was the location of the RSS in 24%, but sponge counts were performed in only 58% of vaginal deliveries. [5] Gawande AA, Studdert DM, Orav EJ, Brennan TA, Zinner MJ. Imaging of Retained Surgical Sponges in the Abdomen and Pelvis, Review. A gossypiboma, also called textiloma or cottonoid, refers to a foreign object, such as a mass of cotton matrix or a sponge, that is left behind in a body cavity during surgery. retained surgical sponge: gossypiboma.5 Complications from retained surgical sponge may include pain, infection (abscess), intestinal obstruction or fistula.6 Two recent cases in Texas involving retained surgical sponges bring into question the two-year statute of limitations and the 10-year statue of repose. The term gossypiboma is derived from the Latin word "gossypium", which means cotton, and the Swahili word "boma", which means place of concealment, thus referring to a retained sponge in the surgical bed. 10), are of mixed or low-attenuation masses containing focal central collections of gas [6, 7] (Figs. A lap tape was retained in the patient's abdomen. Check for errors and try again. The white arrow points to a radiopaque density that is characteristic for the marker placed in a surgical laparotomy sponge in order to make it radiographically visible. Retained surgical sponges are an uncommon event; Medical term for a retained sponge is gossypiboma. On CT, retained sponges are typically seen as a soft-tissue density mass and may show a whorled texture or a spongiform pattern with contained gas bubbles [4]. If it cannot pass the ileocecal valve it can cause complete intestinal obstruction at this level. %PDF-1.5 %���� 11 and 12), although we have also observed peripheral gas collections (Fig. hެ�[k�0�����T[�%��MX/�f-�"�E��1��d�ň��.�@Q( Frequent sites of gossypiboma formation include: Theater 'swab counts' at the end of a procedure before 'closing up' are typically undertaken to prevent retained foreign bodies. ?�����j�~� RS�����Ԯ����(�j��wN�F ��b9C The described CT appearances of absorbable hemostatic sponges, which may be made of gelatin sponge (Gelfoam; Pharmacia and Upjohn, Kalamazoo, MI) or oxidized reabsorbable cellulose (Surgicel; Ethicon, Somerville, NJ) (Fig. In one series, three of 29 retained sponges lacked a visible radiopaque marker [2]. AJR Am J Roentgenol. Radiopaque markers were present on only 62% of retained surgical sponges, which included objects such as towels, Kerlix and undefined types. 2. CT or MR imaging may be helpful in problematic cases. General Considerations. 36 0 obj <>stream Characteristic CT features of abdominal gossypibomas include: A sponge left within the pleural space shows no gas lucencies due to resorption of the air by the pleura. Risk factors for retained instruments and sponges after surgery. 4. Copyright © 2013-2020, American Roentgen Ray Society, ARRS, All Rights Reserved. Radiographs are the most commonly used method to detect retained sponges. This word comes from the Latin word for cotton, gossypium, combined with the Swahili word for place of concealment, boma. In one series, the sponge count was reported as correct in 22 (76%) of 29 patients with retained sponges in the abdomen [2]. 8B). A case report. Gossypiboma of the leg: MR imaging characteristics.

This word combines textile, meaning cloth, and the suffix –oma, which means growth or tumor. The MR imaging appearances of retained absorbable hemostatic sponges have been described in a series of five patients [9] and consist of intermediate T1 and high T2 signal intensity. Although a rare complication nowadays, the true incidence is almost certainly underestimated due to medicolegal implications.

Figure 1: pack extracted from a gossypiboma, low-density mass with a thin enhancing capsule, calcifications deposited along with the network architecture of a surgical sponge. Inadvertently retained sponges are often clinically unsuspected and may be first recognized by imaging. Retained surgical sponge simulating a pancreatic mass. Exudative gossypibomas, however, usually occur early in the postoperative period and may involve secondary bacterial contamination, which can result in various fistulas. endstream endobj startxref 0 Why? %%EOF 8A) because beam-hardening artifacts on the axial images may make the characteristic appearances of the marker less obvious (Fig. A retained sponge should not be misinterpreted as fluid collection, although adjacent abscess formation may be seen (Fig. Retention of surgical sponges or swabs in the abdomen or pelvis occurs with a frequency of one in 100-5000 operations and accounts for 50% of malpractice claims for retained foreign bodies [1, 2].

Radiologically, gossypibomas may be confused with postoperative collections or tumors, particularly with the increasingly common surgical use of absorbable hemostatic materials to control hemorrhage. 2007;189 (4): 814-7.
