“…In the cases of SBO about 50-75% were diagnosed by plain radiography [4,18,29] . Dilated intestinal loops, air-fluid levels, thickened bowel wall could be found in all, 89%, 76% of the cases respectively [9] .…”

AIM: Bezoars (BZ) are the most common foreign bodies of gastrointestinal tract. Clinical manifestations vary depending on the location of BZ from no symptoms to acute abdominal syndrome. When located in small bowel, they frequently cause small bowel obstruction (SBO). We aimed to present our experience by reviewing literature. METHODS:Thirty-four patients with gastrointestinal BZ were presented. The data were collected from hospital records and analyzed retrospectively. Morbidity and mortality rates were statistically analyzed between the subgroups according to SBO and endoscopic or surgical treatment modalities. RESULTS:The 34 patients had phytobezoars (PBZ). Two patients with mental retardation and trichotillomania had trichobezoars (TBZ). More than half of them (55.88%) had previous gastric surgery. Also most of them had small bowel bezoars resulting in obstruction. Surgical and endoscopic morbidity rates were 32.14% and 14.28% respectively. The total morbidity rate of this study was 29.41%. Four patients in surgically treated group died. There was no death in endoscopically treated group. The total and surgical mortality rates were 11.76% and 14.28% respectively. The differences in morbidity and mortality rates between the subgroups were not statistically significant. CONCLUSION:BZ are commonly seen in stomach and small intestine. SBO is the most common complication. When uncomplicated, endoscopic or surgical removal can be applied easily.

“…BZs appear on US as an intraluminal mass with a hyperechoic arclike surface and marked posterior acoustic shadow [15,16,29] . CT-scan demonstrating dilated small bowel loop and a well-defined round, heterogeneous intraluminal mass in distal segment is completely diagnostic.…”

“…However some authors report that this appearance may be similar to small bowel feces described in cases of severe stasis in patient with high-grade small bowel obstruction. Hence, especially in phytobezoars of soft tissue attenuation without air bubbles, it may be very difficult to make a definite diagnosis by CT scan [20]. In our case the CT scan did not reveal any characteristic pattern and an early diagnosis was not possible.…”

“…As demonstrated in this case, computed tomography frequently reveals a 'C-shaped' configuration of dilated, fluid-filled bowel with twisting mesenteric vessels converging toward the site of obstruction [3,4]. A 'beak sign' or tapering of the bowel at the point of obstruction or a 'whorl sign' reflecting rotation of the bowel around a fixed obstruction may be observed [3,4].…”

A 75-year-old man presented to this hospital with abdominal pain. The patient described the sudden onset of: left lower quadrant pain nine-out-of-ten in severity, associated with multiple episodes of bilious vomiting. The patient had not had a bowel movement in 4 days. Physical examination was notable for tenderness to palpation and guarding in the left lower quadrant. Computed tomography of the abdomen and pelvis without contrast material was completed, and demonstrated a closed-loop bowel obstruction involving an ileal loop (Figs.
