Gastrointestinal involvement of endometriosis has been found in 3%-37% of menstruating women and exclusive localization on the ileum is very rare(1%-7%).Endometriosis of the distal ileum is an infrequent cause of intestinal obstruction,ranging from 7% to 23% of all cases with intestinal involvement.We report a case in which endometrial infiltration of the small bowel caused acute obstruction requiring emergency surgery,in a woman whose symptoms were not related to menses.Histology of the resected specimen showed that endometriosis was mainly prevalent in the muscularis propria and submucosa and that the mucosa was not ulcerated but had inflammation and glandular alteration.Endometrial lymph node involvement,with a cystic glandular pattern was also detected.
Gastrointestinal involvement of endometriosis has been found in 3% -37% of menstruating women and exclusive localization on the ileum is very rare (1% -7%). Endometriosis of the distal ileum is an infrequent cause of intestinal obstruction, ranging from 7% to 23% of all cases with intestinal involvement. We report a case in which endometrial infiltration of the small bowel caused acute obstruction requires emergency surgery, in a woman whose symptoms were not related to menses. Histology of the resected specimen showed that endometriosis was mainly prevalent in the muscularis propria and submucosa and that the mucosa was not ulcerated but had inflammation and glandular alteration. Endometrial lymph node involvement, with a cystic glandular pattern was also detected.
