INTESTINAL BEZOARS: RADIOLOGICAL CHARACTERISTICS
|Full paper||Not Available|
Beroars are the most common foreign bodies of the gastrointestinal tract. Clinical manifestations vary depending on the location of bezoar (BZ) from no symptoms to acute abdominal syndrome. When located in the small bowel, they frequently cause small bowel obstruction (SB0). Diagnosis at an early stage is important to avoid their mortality and associated morbidity. We reviewed the clinical data, imaging findings, operative and post-operative data of 11 patients with surgically verified intestinal BZs to assess the value of imaging studies-conventional abdominal radiographs, ultrasonography (US), and computed tomography (CT) - in the diagnosis of intestinal BZs. Intestinal obstruction was the presenting condition in 10 of the 11 patients and BZ-induced SBO was confirmed in these patients. Surgery proved that all BY s were of phytobezoar (PBZ) type and all were of intestinal origin (10 in the small intestine and one in the large intestine), of those of small intestinal origin, 8 were in the ileum and 2 were in the jujenum. Different imaging techniques were conclusive for BZ in 10 of the 11 patients and the imaging findings coincided with the operative data in these patients. Abdominal radiographs and US were performed in all patients, abdominal radiographs revealed BZs in 2 patients, US in 8 and CT scan was performed in 10 patients and revealed BZs in 9.Barium study confirmed the presence of BZ in the only patient who performed such examination. Thus, imaging studies mainly US and CT were reliable methods for diagnosing intestinal BZs and most BZs have characteristic US and CT imaging features. CT is more accurate and may be considered the imaging technique of choice for confirming a diagnosis of intestinal BZs. Because the diagnosis of a BZ as the cause of intestinal obstruction is important as it modifies the approach to treatment, radiologists should be aware of the possibility of BZs in the differential diagnosis of all patients having radiological and clinical features of SBO. Key words Bezoar, phytobezoar, small bowel obstruction, US, CT.
