title: Small bowel obstruction attributable to phytobezoar.
abstract: Small bowel obstruction (SBO) is a common condition encountered in surgical practice. Literature shows divers and many different etiologies for intestinal obstruction. However, bezoars are rarely reported as an etiological factor. A bezoar happens most commonly in patients with impaired gastrointestinal motility. There are four types of bezoars: phytobezoars, trichobezoars, pharmacobezoars and lactobezoars. The most common type is phytobezoars, which are composed of undigested fiber from vegetables or fruits especially persimmons. They are mostly composed of cellulose, tannin and lignin. The commonest phytobezoar reported worldwide is related to the persimmon fruit ingestion. The most common symptom of bezoar-induced SBO is abdominal pain (96-100%). Other common symptoms include nausea and vomiting. Primary small bowel phytobezoars almost always present as SBO. We present an unusual case of SBO caused by a phytobezoar in a 35-year-old patient. Many types of bezoar can be removed endoscopically, but some will require operative intervention.
