Dancing hookworm in the small bowel detected by capsule endoscopy: a synthesized video.

A 38−year−old Chinese woman presented to our hospital, complaining of a 3−month history of black stool passage and dizzi− ness. Laboratory test results included he− moglobin, 40 g/L (normal: 120 ±160 g/L); red blood cell count, 2.08 ” 1012/L (4.0± 5.5 ” 1012/L); white cell count, 15.48 ” 109/ L (4.0 ± 10.0 ” 109/L); eosinophils, 30.1 % (0.5 %± 5 %); platelet count, 424 ” 109/L (100± 300 ” 109/L). Stool examination was positive for occult blood while nega− tive for ova and parasites. Both upper gas− trointestinal endoscopy and colonoscopy showed negative results. Other biochem− istry examination results, including elec− trolytes, and liver and renal functions were within normal limits. The patient underwent transfusion of four units of packed red blood cells. A capsule endos− copy (OMOM; Chongqing Jinshan Scien− ce & Technology Inc., China) performed to evaluate the patient further for occult gastrointestinal tract bleeding showed multiple worms throughout the small bowel (Figure 1). Interestingly, the se− quence of figures from 02 :31 : 26 (h : min: s) to 02 :33:02 showed a hook− worm sticking to and “dancing“ on the small−bowel mucosa. A total of 75 frames chosen from the sequence were turned into a video (Video 1) (Adobe Premiere 6.5; Adobe Systems Incorporated, Califor− nia, USA). The patient refused enterosco− py and further examinations because of poor economic circumstances. Follow−up showed good recovery after treatment with oral albendazole. Endoscopy_UCTN_Code_CCL_1AC_2AG
