Yellow and orange anal soiling in 103 yo from 26 August.why?

[Seinundzeit]

Dear friends, good morning
I thank you always for your availability.
The situation remains unchanged, no evacuation from Sunday 26 evening, when begins yellow soiling with a small diarrea,now continues small losses sometimes yellow sometimes orange, which never flows, but dirty only the anus.
I wanted to add that on the 21st I took her to an ecodoppler in the hospital, after having made 14 days of antithrombotics (6 days of Fluxum 4250 +8 days of Vessel vials), for suspected thrombosis in one leg and she was therefore tighted with belts in barrella, had the two things caused damage to internal organs?
Because, I repeat, all this yellow I've never seen, constipation yes even 4 -5-6 days.
Nothing in rectal exploration.
Do I give her the things that make her go to the bathroom, that is, oranges, squash, vaseline oil?
bound
Best regards
