While doing upper gastro intestinal endoscopy hookworms are most commonly found in duodenum and very rarely in stomach. But interestingly multiple hookworms were seen in the jejunal part of gastrojejunostomy stoma while doing upper gastro intestinal endoscopy in a 45 year old female patient who had undergone Truncal Vagotomy and gastrojejunostomy. Such endoscopic finding has not been reported so far. The patient underwent upper gastro intestinal endoscopy since she had dyspepsia for the last few months. But infection with multiple hookworms was found to be the cause of her dyspepsia after endoscopy. Hence upper gastro intestinal endoscopy is a very useful investigation to diagnose hookworm infection of duodenum, stomach and even the jejunal part of gastrojejunostomy stoma.
