“…CT-scan demonstrating dilated small bowel loop and a well-defined round, heterogeneous intraluminal mass in distal segment is completely diagnostic. The mass could be outlined by the bowel wall and presented characteristic internal gas bubbles-soft tissue appearance of BZ [9,20,30,31] . Endoscopic investigations could show all of gastric BZs and only 12% of small bowel BZs [8,32] .…”

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.

“…23,24 The sensitivity and specificity of abdominal radiographs in the evaluation of mechanical small-bowel obstruction is poor, with failure to confirm diagnosis in a third of cases. [25][26][27][28] Thus, in these patients, further imaging is inevitably required. 25 These often include ultrasound or CT with contrast.…”

“…26,28 If abdominal radiography is suggestive of SBO, it is frequently followed-up with a CT scan. 27,29 Dilatation of small bowel is a common finding on plain abdominal radiograph which could suggest small bowel obstruction, paralytic ileus or intra-abdominal disorder. 30 Such patients will eventually require a CT scan to identify the cause of the blockage.…”

Citation ABSTRACTPlain abdominal radiographs are often used as the first line investigation in diagnosing abdominal pathologies such as bowel obstruction and gastrointestinal perforation. However, their interpretation can often be non-specific. Given the reduction in radiation doses in recent years, This article reviews the role of plain abdominal radiographs and other imaging modalities in bowel obstruction and gastrointestinal perforation.

“…Alguns autores demonstraram que a TC poderia ser mais útil quando os achados do RX de abdome fossem não conclusivos para o diagnóstico de AAO, o que ocorreria em cerca de 20% a 52% dos casos (3) . Alguns dos benefícios mais específicos da TC seriam sua capacidade de diagnosticar tumores, abscessos, infartos de segmentos intestinais, além de outras causas menos comuns de obstrução intestinal (3) . No caso aqui apresentado ficou bem clara a forma objetiva que a TC identificou a obstrução, o "plastrão" de alças, além de identificar o "osso" (fúrcula do esterno) como o fator causal do AAO.…”

“…Didaticamente, poder-se-ia considerar como dilatação do intestino delgado à TC quando identificássemos alças delgadas com mais de 2,5 cm de diâmetro, sendo que, eventualmente, poderíamos identificar também, a transição com o intestino delgado não dilatado, conforme referido por alguns autores (3) .…”
