Small bowel obstruction secondary to crab shell bezoar: A case report.

Small bowel obstruction is a common surgical condition that needs surgical intervention if conservative measures fail. Bezoar is a rare aetiology of small bowel obstruction with incidence of 4.5%. The bezoars can be grouped, according to the content, into four common types: phytobezoars, trichobezoars, pharmacobezoars, and lactobezoars. However, unusual bezoars like plastic bezoars and metal bezoars have been reported too. Herein, we report a case of an elderly lady who was treated for small bowel obstruction due to crab shell bezoar. This is the first case reported in literature. Ingestion of large intact pieces of crab shell should be avoided due to the potential of causing small bowel obstruction.
