Extravesicular gossypiboma[1]

Gossypiboma (textiloma) is a term for the surgical complications following retention of surgical swabs within a canine patient[2] after orthopedic surgery or, more commonly, ovariohysterectomy.

This relatively rare post-operative complication can result in a number of clinical symptoms such as incontinence[3] or neoplasia due to granulomatous reaction to retained sponges[4].

A presumptive diagnosis is usually established on radiographic evidence of a linear foreign body associated with prior surgical procedures. Use of ultrasonography or fine-needle aspiration[5] may assist diagnosis, but definitive diagnosis requires surgical exploration of the foreign object.

Treatment by surgical removal of the surgical sponges is usually curative.
