Hi, this question is like an exam. Why were four surgeries performed after the intestinal obstruction. It is very important to know what was done in these four surgeries. There is always a problem with intestinal bleeding. These include: tumors, inflammation, vascular malformations, and the best way to understand these is by colonoscopy, barium enema, or angiogram. Angiography is best done when bleeding is present; otherwise, the negative rate is high. The contraindication to barium enema and colonoscopy is that you cannot have an intestinal fistula. The last trick is in surgery. But before surgery it should be said that the cause can basically be found. Thanks!
