Utres surgery went wrong. Feeling sad.

Mom underwent hysterectomy, but doctor made some mistake causing huge problem and resulted in 2nd surgery Actually due to doctors ignorance there was an injury to rectum which they did not notice..after 1 day , mom stomach swelled with pain gastric and problem in breathing.. Diffrent doctor reviewed and found the mistake and did initiate operation ...it was very serious in nature and an enductomy was done.. hole near stomach for fecus. Mom was in ventiliter for 2 days , now shifted to room.. but she looks very weak and in pain .. Doctor says they have treated rectum and it takes around 5 months for healing after that they will do 1 more operation and will fix the rectum issue. We are very scared and worried.. Can someone suggest how long it will take and how my mom can be normal again She was fit and fine and very courageous women .. looking at her feeling sad ...
