Textiloma in leg – A Diagnostic Quandary

Textiloma, gossypiboma or muslinoma are various terms used for this entity. Reported estimate of all the retained foreign bodies (RFB) is 1 in 1000 to 1 in 10,000 [1] and in 80 percent of them a surgical sponge is the culprit [2]. The reported incidence of gossypiboma varies from one per 3001000 for all the surgical procedures [3].This is probably an underestimate due to underreporting because of medico legal consequences. Most of such cases are reported in the abdominal cavity but the chest, the extremity and the cranial cavity have also been reported [4]. We report one such case in the leg.

A 28 year old male presented to emergency plastic surgery department with complaints of multiple discharging sinuses on the posterior aspect of the right leg for the last 8 months. He had a history of injury to the right leg in a blast about 1 year back for which he was operated (details not available). He was again operated 4 months later for an abscess at the operative site after which he developed multiple discharging sinuses in the lower third the right leg ( Figure 1).

The case
On examination there were two sinuses discharging purulent material. There was associated dense scarring in the surrounding tissues. An X ray and MRI was done to look for underlying osteomylitis, any abscess or soft tissue growth.MRI was suggestive of a well defined ,walled off collection in the posterior aspect of the right leg in the intramuscular plane extending upto the subcutaneous plane ( Figure 2).
This information was shared with the patient and his family was counseled about the plan.
On exploration, a ball of cotton fibres encapsulated by scar tissue was seen engulfed in the medial belly of the Gasrtocnemius muscle with ramifications of pus pockets all around, two of it forming cutaneous sinuses. Gossypiboma was excised along with the scarred tissue and the involved fibres of muscle belly and tendo achiles. (Figure 3) The wound cavity was closed in layers over a drain which was removed on third post operative day.
Histopathology showed formation of acute over chronic inflammatory granulation tissue and presence of many foreign body giant cells around thread like foreign material. No evidence of granuloma or malignancy was seen.  Textiloma or gossypiboma is a term used to define a retained foreign body after surgery, most commonly a gauze piece. The first such case was reported in 1884 by Wilson [5]. The incidence of this entity varies from one in 1000-1500 for intra abdominal operations and one per 300-1000 for all the surgeries [3]. The true incidence is difficult to measure due to under reporting because of its medicolegal implication. Diagnosis of gossypiboma or retained foreign body, after any surgical procedure, has often led to litigations and huge amount of compensation and legal cost expenses [6].

Discussion
At 6 weeks follow up the wound is well healed and the soft tissues of the leg appears supple.
Various absorbable and non absorbable materials are used to control intra operative bleeding .These may be left inside intentionally or unintentionally. This leads to an acute inflammatory reaction around that material which subsides with resoprtion of this material. At times, exuberant inflammatory reaction leads to formation of pseudo capsule around this foreign body. The type of reaction determines the presentation of the patient. It may be exudative leading to discharging sinuses, fistulas and abscesses or a dense fibrosis presenting as a pseudomotor [7].
Diagnosis of gosspiboma is difficult to due to its nonspecific clinical features .A history of previous surgery may provide a clue. It should be kept in mind that the time interval between surgery and presentation may be as long as up to 15 years [8]. Features of various imaging modalities are also not very specific. Features such as Radio opaque marker or a whirl like image on X ray (35%), hyper echoic mass with hypo echoic rim on ultrasound (34%) and presence of a round mass with a dense central part and enhancing rim on CT scan (61%) may be helpful in assessment [3].
