<s>[INST] Hi.mom was diagnosed 3c endometrioid adenocarcinoma 3 years ago. For nearly a month she is vomiting black stuff and constipated. After passing motion via colostomy, she finds relief and there again, constipated. No mass up to 40cm the colonoscopy was inserted. Could this be due to adhesions? [/INST] Hi, dairy have gone through your question. I can understand your concern. She may have some adhesion or stricture. So obstruction in the gastrointestinal tract causing this problem.  She should go for GI endoscopy and ultrasound abdomen. Then she should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
