Pelvic endometriosis in 3-37% of cases involves the intestinal tract, mainly 
sigmoid colon and rectum. In clinical practice endometriosis of the intestinal 
tract is rarely diagnosed and usually after long-lasting symptoms. During 3 
years we treated only 2 women with this disease and therefore we want to report 
this seldom disorder. One woman had been diagnosed as having had rectal 
endometriosis before she was admitted to the hospital and the other one was 
admitted because of complications after laparoscopic treatment of pelvic 
endometriosis. In spite of typical signs of intestinal tract endometriosis, the 
proper diagnosis was made after several years of symptoms in one woman and in 
the second female histopathology of removed sigmoid colon because of its lesion 
finally revealed endometriosis. Laparoscopy seems to be the best diagnostic 
method of intestinal endometriosis and its treatment is to remove the involved 
part of the bowel together with endometriotic foci and surrounding tissues. 
Cyclical intestinal endometriosis symptoms correlating with menstrual cycle 
should always draw our attention to this rare disorder.
