ABSTRACT
Estudios recientes han descrito en el sigmoides una colitis segmentaria que compromete el área peridiverticular, la cual respeta el resto del colon y recto. Esta enfermedad es similar a la colitis ulcerosa en su cuadro clínico, apariencia endoscópica e histológica, sin embargo, por definición respeta la mucosa rectal y el colon proximal al sigmoides. Se han descrito casos de progresión de colitis segmentaria a colitis ulcerosa.
Recent articles have described a segmental colitis involving an area of diverticulosis at the sigmoid colon level, but sparing the rest of bowel. This disease is similar to ulcerative colitis in its clinical presentation and endoscopic and histologic appearance, however by definition does not involve the rectum or proximal colon. Few cases have been reported in which there was progression from segmental colitis to typical chronic ulcerative colitis.
