A Dieulafoy's lesion is a rare cause of massive gastrointestinal (GI) bleeding. It represents an abnormally dilated submucosal artery that erodes the overlying epithelium in the absence of a primary ulcer. These lesions are usually located in the stomach, nevertheless, they have been found in all areas of the GI tract, including the oesophagus, duodenum and colon. Bleeding episodes are often self-limited, although bleeding can be recurrent and profuse. The case describes a 50-year-old woman who developed haemorrhagic shock secondary to a rectal Dieulafoy's lesion and discusses the diagnostic and therapeutic approaches.
Dieulafoy 病变是一种罕见的胃肠道（GI）大出血原因。它代表了一种异常扩张的黏膜下动脉，在没有原发性溃疡的情况下侵蚀了上方的上皮。这些病变通常位于胃中，但也已在胃肠道的所有区域中发现，包括食管、十二指肠和结肠。出血发作通常是自限性的，尽管出血可能会反复发作且大量。本病例描述了一位 50 岁女性因直肠 Dieulafoy 病变导致出血性休克，并讨论了诊断和治疗方法。
