Gossypibomas are rare in modern surgery; however, present a significant medico-legal dilemma when they do arise. Treatment is surgical retrieval after identification. When seen years after the original procedure, a diagnostic dilemma arises. Diagnosis via radiologic means is often unreliable, thus, diagnosis involves excision or core needle biopsy. In this unique case, we were forced to make a diagnosis without tissue confirmation due to patient request. Gossypibomas have been described as having highly variable appearance on computed tomography, and thus, radiologic diagnosis is considered unreliable. Often, the characteristic spongiform appearance typically used to describe chronic gossypibomas is not observed. In our case, matching the radiodensity of surgical gauze with that of the gossypiboma helped to make a correct diagnosis, suggesting that radiologic diagnosis is possible in certain cases.

| Introduction|| |
Gossypibomas are increasingly rare with advances of modern surgery. However, they do occur from time to time, in general surgery or specialties such as cardiothoracic surgery or neurosurgery.,, The rate of retained surgical foreign bodies has been published in literature to be 0.3–1.0/1000 surgeries in the case of abdominal surgery. However, given the medico-legal challenges that this problem presents, this number may be underestimated due to under-reporting. Risk factors for retained surgical objects include high intraoperative blood loss, duration of operation, sub-procedures, unexpected intraoperative factors, and incorrect or lack of surgical counts. Sequelae of retained foreign bodies have been reported to include, in severe cases, intestinal obstruction, urinary retention, fistula formation, perforated viscous, abscess formation, sepsis, and transmural migration (most commonly intestinal).,, However, because of nonspecific symptoms and presentation that can occur years after surgery, a high index of suspicion is necessary in any patient with surgical history who presents with subacute or acute abdominal pain. Usually, the diagnosis is straightforward, if anticipated, and is made either by excision or core needle biopsy. This was a unique situation where the diagnosis was made without tissue confirmation.
Generally, gossypibomas present variably on computed tomography (CT) scan which makes radiologic diagnosis difficult. The characteristic appearance that has been described in literature is a spongiform pattern that occurs when air becomes trapped in the object. However, only a minority of gossypibomas have this appearance on imaging. They can otherwise present either as low density, high density, or heterogeneous structures on CT scan.
| Case Report|| |
A 61-year-old Caucasian female with a known history of ovarian tumor that had been successfully treated previously, presented with lower gastrointestinal bleeding. Colonoscopy revealed normal colon with grade I hemorrhoids in the rectum. However, CT scan of the abdomen revealed a soft tissue mass with hyperdense content in the right lower abdomen [Figure 1]. She had a history of portal and splenic vein thrombosis with an extensive collateral formation that involved the abdominal wall. Comorbidities included asthma, diabetes mellitus, left hemiparesis, hypertension, congestive heart failure, atrial fibrillation, hypothyroidism, lower limb deep vein thrombosis with pulmonary embolism, anemia, and portal hypertension with massive splenomegaly. The patient refused any invasive diagnostic or therapeutic procedures unless the incidentally discovered mass was a tumor. A preprocedure diagnosis was imperative.

Incomplete tumor resection and recurrent ovarian tumor were discussed despite the fact that she was considered cured from her ovarian tumor. The possibility of gossypiboma with surrounding tissue reaction was entertained in view of the regular circumscribed nature of the mass and the uniform nature of its hyperdense content. The radiodensity of the hyperdense material within the intra-abdominal mass was similar to that of surgical gauze as measured in Hounsfield units, confirming the diagnosis of gossypiboma. The patient did not undergo any procedure and is still alive 3 years after her diagnosis suggesting that the mass does not represent a malignancy, and the diagnosis of gossypiboma was correct.
| Discussion|| |
Gossypiboma is derived from the Latin word “gossypium”-cotton and boma-place of concealment. The risk of retention of a foreign body after surgery significantly increases with high intraoperative blood loss, long operations, multiple sub-procedures, incorrect or lack of surgical counts, unexpected intraoperative events, or cases involving multiple surgical teams. Recent meta-analysis did not identify increased body mass index or emergency surgery as statistically significant risk factors. Gauzes account for two thirds of retained surgical items while instruments account for the rest. Although most commonly detected in the abdomen and pelvis, it has been associated with all types of procedures, including cardiothoracic surgery  and neurosurgery. Because gossypiboma is not anticipated, it is frequently misdiagnosed and oftentimes radical surgical procedures erroneously follow.,,, However, while they are not often anticipated, gossypibomas are theoretically completely preventable. Because of nonspecific symptoms and presentation that can occur years after surgery, a high index of suspicion is necessary in any patient with surgical history who presents with subacute or acute abdominal pain. Sequelae of retained foreign bodies have been reported to include, in severe cases, intestinal obstruction, urinary retention, fistula formation, perforated viscous, abscess formation, sepsis, and transmural migration (most commonly intestinal).,,
Definitive diagnosis and treatment is determined by retrieval of the foreign body. Previous reports have usually used excision or core needle biopsy to obtain tissue, which on histopathology had revealed gauze and confirmed the diagnosis. Laparoscopic retrieval of the retained foreign body has been described in cases of early detection. However, diagnosis of gossypibomas is often delayed, and the foreign body may not be detected until years following the initial surgery. Endoscopic retrieval has been described in cases of transmural migration into the lumen; however, surgical retrieval of the foreign body is the “gold standard”. In the literature, radiologic diagnosis alone has not been shown to be reliable due to the nonspecificity of retained surgical sponges on imaging and the variability in appearance depending on the location and qualitative characteristics of the sponge itself.
In the current case, we were faced with an extraordinary situation where the patient refused all procedures unless her abdominal mass was a tumor. After counseling, the patient about the potential for mistake with such an approach, the diagnosis of gossypiboma was made based only on CT findings. In our case, we identified the foreign body by matching the Houndsfield units on imaging to that of a surgical sponge. The patient is still alive 3 years after the diagnosis. An abdominal CT done recently for a different indication revealed that the mass has remained approximately the same. In the situation of this particular patient, our experience suggests that in the appropriate situation, radiological diagnosis can be made without other confirmatory correlation.
Because of the medico-legal implications associated with retained surgical objects, vigilance and prevention is paramount. Strategies that have been suggested in literature for prevention include radiography at the completion of any complex procedure prior to wound closure, thorough inspection of the cavity prior to closure, more conservative use of sponges and avoiding the use of small sponges, consistent adherence to counting procedures, and proper attention to the operating room environment., 4, ,,, Maintaining a high index of suspicion can be invaluable in this setting.
| Conclusions|| |
Surgical retrieval remains the gold standard for definitive diagnosis and treatment of retained surgical foreign objects; however, in certain cases, when the patient refuses surgery, alternative methods must be considered. This was a suboptimal situation where surgical retrieval was not possible, and as such, a radiologic diagnosis was made and the patient was treated with observation. Very rarely in the literature is radiologic diagnosis alone suggested to be adequate for the diagnosis of gossypibomas (in particular, surgical sponges). This is because retained surgical sponges can present such a variable appearance on imaging.
Even in the case of adequate diagnosis, refusal of surgery presents an additional treatment dilemma. There are no studies demonstrating the safety or efficacy of observation or conservative treatment of retained surgical foreign bodies; thus, there are no established recommendations or guidelines regarding observation of retained objects. Fortunately for the current patient, she remained asymptomatic after the standard of care (e.g., surgery) was taken off the table as an option. However, by declining surgery the patient placed herself at risk for a variety of adverse events such as intestinal obstruction, urinary retention, transmural migration, fistula formation, perforated viscous, abscess formation, and sepsis. Even with surgical retrieval being available, prevention remains the best solution for reducing the risk for gossypibomas or other retained surgical objects.
