The return of Medical Check up and my first operation

Today is the first time me and my groupmates were given a chance to have a go at working in an operation. After doing practices on corpse materials, our operative surgery teacher gave us a chance to do a real operation on a rabbit.
The operation we were about to do was an abdominal surgery which is a side to side anastomosis of the large intestine (resecting a part of the large intestine and reattaching the remainding intestine back with each other)
We were divided into 2 groups, one group is assigned to cut open the rabbit for accessing to the intestines and its closure after the operation, while the 2nd group was responsible for doing the intestinal operation.
After giving anaesthetics to the rabbit, we prepared it for the operation by removal of the hair. Though, the rabbit seemed to be a bit resistant to the anaesthesia and was still moving around especially after we started to cut the rabbit's abdomen open which in turn cause a lot of commotion in the operation teather as it was our first time doing such an operation and were all nervous.
I was in charge of suturing the posterior wall of the intestine (sewing up one part of the intestine together) while others were assigned different jobs. Another situation arised when we were putting back the intestines into the abdominal cavity after we finished the operation on the intestine.
The narcosis the rabbit had was wearing off and when we tried to put the intestines back into the abdomen, the rabbit cried out of pain. Its cry was such a pitiful cry and will always ring in my ears. Luckily, no more problems turn up after that small incident and we managed to finish the operation without too much of an error. We took more than 4 hours for the operation and finally understood how tiring a surgeon's work is.
I hope that the rabbit survives from our operation and am very sorry for causing any pain to it during the operation. We are all also thankful to it for being our first ever hands on experience of an operation.
Tomorrow, me and my groupmates will be having our anual medical check up during which, we will be poked and violated all over, with the worse being that we will have a cotton bud shoved up our arse and urinary tract to get a sample of our tissues there. That is what I am not looking forward to. Hope that I will be exempted from the excruciating pain.
