Síndrome de Lemmel: ictericia obstructiva secundaria a divertículo duodenal yuxtapapilar. Reporte de un caso

Lemmel syndrome is a rare entity, characterized by the presence of obstructive jaundice secondary to the presence of a periampular duodenal diverticulum. Periampular are the most common, in 75%; of these, those located 2-3 cm from Vater’s ampulla are known as juxtapapillary diverticula, most of which are extraluminal and acquired. Currently the diagnosis is made using endoscopic retrograde cholangiopancreatography or endoscopic ultrasonography, since both can confirm the diagnosis. Endoscopic sphincterotomy and biliary stent placement is the treatment of choice in case of biliary or pancreatic complications. We report the case of a 67-year-old patient with Lemmel syndrome.
