Endoscopic removal of an immigrant (Taenia saginata) from the stomach of a geriatric patient

Unusual oral expulsion of adult Taenia worm through vomiting

“…Owing to its attachment to the intestinal wall by the scolex and the strong gastric acidic milieu , the tapeworm is not expected to reach the stomach. Nevertheless, upper gastrointestinal endoscopy for chronic dyspepsia has accidentally detected the worm in the stomach 10 , 11 .…”

Taenia: An Uninvited Guest

“…However, there have been occasional case reports of finding this helminth in the mouth [ 10 ] and nasal expulsion of this worm along with a nasogastric tube [ 11 ], as well as finding this worm in the pancreatobiliary system [ 6 , 7 , 12 ]. In addition to the tight binding of the parasite to the intestinal villi, upward migration of the worm could be mainly inhibited because of the high gastric acidity [ 9 ]. In this patient, atrophic gastritis caused by chronic H. pylori infection and long-term administration of proton pump inhibitors could be the most important reasons for upward movement of this worm.…”

“…In this patient, atrophic gastritis caused by chronic H. pylori infection and long-term administration of proton pump inhibitors could be the most important reasons for upward movement of this worm. Successful endoscopic removal of a Taenia was reported previously in the medical literature but we were unsuccessful in pulling it out due to its great length [ 9 ]. Another endoscopic treatment is available in some areas.…”

“…Although T. saginata is mostly seen in the small intestine, migration of this worm to the stomach is very rare [ 8 , 9 ]. We report a wandering tape-worm at the stomach of a rural woman who was in contact with livestock and livestock products.…”
