A 31-year-old male presented with two episodes of hematemesis over 48 hours duration. Patient had been diagnosed to have duodenal ulcer by an upper GI endoscopy which had been performed two years back for dyspeptic symptoms. The ulcer had subsequently healed after medical management. There was no history of alcohol abuse or intake of NSAIDs. There were no significant findings on clinical examination apart from pallor and tachycardia (Heart rate - 110/minute). His hemoglobin was 6.8 gm/dl and hematocrit was 20%. Coagulation parameters were normal. The nasogastric aspirate was clear. An upper GI endoscopy revealed normal esophagus and stomach. The duodenal bulb was deformed but no active ulcer was seen. Few clots were seen adherent to the postbulbar mucosa that appeared grossly normal (Figure 1). The patient rebled the next day. A repeat endoscopy showed an actively bleeding vessel in the postbulbar duodenum. The surrounding mucosa was normal (Figure 2). These findings were suggestive of a DL of the duodenum. A peri and intralesional injection of 1:10,000 adrenaline solution controlled the bleeding. Subsequent recovery was uneventful. The video recording of the first endoscopy was reviewed focussing on the lesion bearing segment (the post bulbar duodenum). The lesion escaped our attention possibly because it was covered with a tiny clot and the surrounding mucosa was normal. Patient continues to be well at a follow-up of eight months. Repeat endoscopy performed one month and six months after his discharge showed normal mucosa in the involved area.
