Discussion (Related Text)
A phytobezoar is a concretion of poorly digested fibers, fruit seeds, and pulpy fruits, especially oranges and persimmons, causing small intestinal obstruction usually after migration of a gastric phytobezoar. However, the obstruction is also caused by a primary bezoar (an enterolith) formed in the small intestine in association with underlying small bowel diseases such as diverticula, strictures, or tumors.239 Gastric surgery is the most predisposing factor for the development of phytobezoar; other factors include poor mastication, autonomic neuropathy, and overconsumption of foods with a high fiber content.316 Early diagnosis is important because phytobezoars provoke decubitus ulcer, pressure necrosis, perforation, and even strangulation if the diagnosis is delayed.The most common cr findings of phytobezoars include a round or ovoid or a long sausage-shaped mass containing mottled gas at the obstructed site Phytobezoars are rarely manifested as a soft tissue mass without gas, resembling an intraluminal tumor or intussusception. In these cases, barium study may give the clue in suggesting the diagnosis, and the diagnosis should be suspected when intraluminal filling defects appear to be mobile or multiple.
