Abstract: Objective The purpose of this study was to assess the value of imaging studies--conventional abdominal radiographs, sonography, and CT--in the diagnosis of gastrointestinal bezoars. Methods and methods A review was made of the radiologic findings of 17 consecutive patients with surgically verified gastrointestinal bezoars over a period of 51 months. Results Twelve patients had a history of previous gastric surgery. In no patient was a bezoar clinically suspected. Phytobezoars were recorded in 16 patients and a trichobezoar in only one. A total of 33 bezoars were identified at surgery. Two patients had isolated gastric bezoars, whereas 15 patients had bezoars located in the small bowel. Among the latter group, associated gastric bezoars were found in eight patients, and five patients had multiple intestinal bezoars. Abdominal radiographs revealed bezoars in three patients, sonography revealed bezoars in 15, and CT revealed bezoars in all 17. Seven patients had associated gastric bezoars revealed at CT versus only two patients with gastric bezoars revealed at sonography. CT revealed multiple intestinal bezoars in five patients whereas sonography revealed them in only two patients. Conclusion Both sonography and CT are reliable methods for diagnosing gastrointestinal bezoars. CT is more accurate, however, and exhibits a quite characteristic bezoar image; in addition, this imaging technique is able to reveal the presence of additional gastrointestinal bezoars.

TL;DR: A rare case of bezoar formation is reported, associated with a biliary stent, in a patient with no prior gastrointestinal disease, highlighting an unusual complication of biliary stent placement in a healthy individual.
Evaluation of the risk factors for severe complications and surgery of intestinal foreign bodies in adults: a single-center experience with 180 cases

TL;DR: Intestinal FBs, often localized in angulation, are likely to be misdiagnosed because most patients do not provide a history of FB ingestion, and surgery is not mandatory in clinically stable patients with small and contained perforations.
Phytobezoar: An Unusual Condition Leading to Small Bowel Obstruction
TL;DR: Preoperative CT examination can provide invaluable information about the level of obstruction, etiology, and the existence of additional pathology and thereby help plan the type of surgical procedure required.
Sonography of the pediatric gastrointestinal system.
TL;DR: An overview of the ultrasound characteristics of some of the most frequently encountered pathologies as well as some more rarely encountered entities is presented to familiarize the reader with key sonographic features of both congenital and acquired gastrointestinal pathologies in children, making them more easily recognizable.

TL;DR: Plain film radiography and CT had similar overall accuracies in showing small-bowel obstruction of various severities and should remain the initial method of imaging patients with suspected small-Bowel obstruction.

TL;DR: Bilateral truncal vagotomy plus pyloroplasty and a excessive ingestion of vegetable fiber are the main factors predisposing to bezoar formation.

Small bowel phytobezoars: detection with radiography.
TL;DR: The obstruction caused by small bowel phytobezoars frequently occurred in the jejunum or proximal ileum, more proximally than has been reported in previous series.

TL;DR: With the increased use of CT in the evaluation of patients with non-specific abdominal pain, it is important to recognize the CT appearance of bezoars, as this diagnosis is often not suspected clinically.
