Abstract. Gossypiboma is a retained surgical cotton matrix material in the body after a surgical procedure. Cases are rarely reported due to medico-legal concerns. Although infrequent, it causes serious morbidity and even mortality if left undiagnosed. We present the case of a trans-mural migration of gossypiboma and a review of the literature. Gossypiboma’s trans-duodenal migration is a rare complication of retained gauzes. Cases reported in the literature were easy to diagnose based on clinical grounds and endoscopic studies.

Gossypiboma duodenal: reporte de un caso y revisión de la literatura
Resumen. La palabra gossypiboma define una gasa o matriz de algodón retenida en el organismo después de un procedimiento quirúrgico. Se reportan con poca frecuencia debido a las implicaciones médico-legales. A pesar de ser poco frecuentes, pueden ser causa de morbilidad si no se diagnostican. En el presente trabajo se reporta un caso de un gossypiboma con migración transduodenal. La migración transduodenal de un gossypiboma es una complicación rara que suele diagnosticarse sin dificultad con base a la clínica y a la endoscopía.

INTRODUCTION
Items left behind unintentionally in patients following surgery are commonly referred as retained foreign bodies. These objects include needles, knife blades, surgical instruments and above all surgical sponges. Gossypiboma (textiloma, gauzeoma, muslinoma, cottonbaloma, cottonoid) is the term used to describe a retained “mass of cotton”. It is derived from the latin word gossypium” (cotton) and the Swahili voice “boma” (place of concealment) (1) and makes reference to the cotton matrix and surrounding inflammatory foreign body reaction or granuloma (2). It replaced the former Latin expression corpus alienum intraabdominalis (3). The retention of surgical sponges can result in significant morbidity and even mortality if left undiagnosed and, once diagnosed. serious medico-legal consequences to the surgeon and the hospital where the procedure was performed (res ipsa loquitur= the thing itself ¿speaks and in common law is a synonymous of negligence). It mandates a direct apology to the patient, hospital payments for all costs incurred as a result of the event and costly legal proceedings if the patient claims for any compensation (4,5).
CASE REPORT
A 34-year-old female patient, who had undergone open cholecystectomy four months earlier, was brought to the emergency room of our hospital with a one-month history of diffuse, mild to moderate colicky abdominal pain that worsened by the ingestion of most foods. Two weeks before admission, she developed immediate post-prandial non-bilious vomiting, marked halitosis, anorexia, flatulence and a progressive body weight loss of more than 10 kg over this period. On admission she appeared chronically ill. The abdomen was soft and not tender without distension or organomegaly. A 5-cm right subcostal surgical scar was noted. Bowel sounds were present and normal. Findings of the remainder of her examination were unremarkable. Laboratory tests revealed a mild thrombocytosis (578.000) and slightly elevated alkaline phosphatase; 172 U/L (37-100 U/L). A plain abdominal radiograph showed a radioopaque string as well as a whorl-like opacity (Fig. 1). A diagnosis of upper intestinal obstruction was made and based on the presence of this finding, a retained surgical sponge was highly suspected. Upper digestive endoscopy confirmed the suspicion and disclosed a gauze between the bulb and the second part of the duodenum, as well as a Forrest III ulcer (Fig. 2). Attempts were made to retrieve the foreign body with the biopsy forceps and a polypectomy snare without success. The patient went to the operating room and a laparotomy was performed. The retained sponge was dissected out with no intestinal resection. The duodenal defect was closed. The patient did well postoperative and was successfully discharged on the sixth day.

DISCUSSION
Gossypiboma is an important and preventable iatrogenic complication whose delay in diagnosis and treatment can lead to serious morbidity and mortality (6). The magnitude of the problem is not entirely known because cases are rarely reported due to medico-legal concerns and adverse publicity (6) A PubMed search using the terms “gossypiboma” and “gossypiboma and duodenum” were performed for English articles. Latin American articles written in Spanish or Portuguese were also reviewed with LILACS’s database search engine with the terms “gossypiboma” and “gossypiboma y duodeno” used in the search. Articles were selected by the authors based on their experience and clinical relevance. The cases reported were summarized.
The first medical case of gossypiboma was reported by Wilson in 1897 (7). The first malpractice suit related to it occurred in 1933 [5]. The incidence of retained foreign bodies following surgery has a reported rate of 0.01% to 0.001% of which gossypibomas account for 80 % of the cases (2). It has been classically estimated as 1 in 1000 to 1500 intra-abdominal open surgeries and in 1 in 3000 in all surgical interventions (6). More recently, studies based on malpractice claims found a 1 in 8801 to 1 in 18760 (4)]. However these figures omit large numbers of patients that go underreported. The retained foreign bodies induce two types of inflammatory reactions. The exudative type leads to abscess formation and chronic fistulae and usually become symptomatic in the early post-operative period.
The fibrotic type produces an aseptic fibrous reaction that creates adhesions and encapsulation, leading finally to foreign body formation and pseudotumors (6) The time interval between the surgical procedure and clinical presentation ranges from the immediate postoperative period to decades after surgery (11 days to 28 years) (5), with approximately 50 % of retained gauze pieces being discovered at least five years after surgery and one third of all patients were symptom free (8). These patterns of inflammatory reactions and the location of the sponge are responsible for the two classical forms of clinical presentation (9). Symptoms usually are nonspecific, ranging from none (incidental finding) to fatal, depending on the site and type of complication resulting from the retained foreign body (10). The acute presentation is characterized by a septic course with abscess generation and intestinal obstruction secondary to granuloma formation and adhesions. The delayed or chronic form (months or years after surgery) is the result of sponge adhesion and encapsulation to the surrounded tissues. Expressed clinically, depending on the location of the foreign body, as sub-acute intestinal obstruction, tumor, fistula, free perforation, erosion into the bowel or vessels, extrusion of the sponge via rectum and migration into the bladder (11,12). Sponge retention is classically associated with emergency surgery, gynecological or upper abdominal After surgeries, unexpected changes in the surgical procedure, disorganization, long procedures, unstable patient condition, inexperienced staff and obesity (9).
The diagnosis may be suspected based on the antecedent of a previous surgical procedure and confirmed by the presence of a radio-opaque marker in the plain abdominal films. These markers however, slowly disintegrate and fragment over time and as time passes since surgery, while clinical concern for this condition slowly declines to the point to rule out the possibility (11). After the gossypiboma’s diagnosis is made, the removal of the retained sponge either by open surgery, laparoscopy or endoscopy depending of clinical presentation and facilities available, is highly recommended to prevent severe complications that may lead even to death (15-22 %) (13,14). There are however some reports of conservative management of these patients (15). Migration of the gossypiboma may occur externally (extrusion) through a fistulous tract or internally, when it is adjacent to a hollow viscus (rectum, vagina, bladder, or intestinal lumen) (10).
The small intestine is the most commonly affected site due to its large surface (jejunal and ileal segments) and thin wall which offers the least resistance (16) Post cholecystectomy gossypibomas are rare and even more rare the reports of transduodenal migration (11). Endoscopy may be a diagnostic useful tool when the gauze migrates to the lumen of the digestive tube, and in some cases allows the retrieval of the foreign body with a snare, biopsy forceps or a basket. In selected cases, endoscopicultrasound-guided transmural drainage can be the first approach, followed by endoscopic removal if it succeeds (17). Clinical presentation includes the presence of an abdominal mass, intestinal obstruction, discharging sinus, intra-abdominal abscesses and peritonitis (6). A correct preoperative diagnosis is made in about one-third of the patients (18). The presence of a foreign body should be kept in mind in the differential diagnosis of any postoperative patient who presents with pain, infection or a palpable mass (19). The practice of counting surgical gauzes pre- and post-operatively, and the use of radiopaque markers have significantly reduced the incidence of this complication (20). As a conclusion, gossypiboma is a diagnostic dilemma due to its nonspecific symptoms and variable radiological findings (6). Trans-duodenal migration is rare and generally, presents with signs and symptoms of upper gastrointestinal obstruction. Endoscopy may be helpful in achieving a rapid diagnosis and in some cases in retrieving the foreign body.
