I am in Glasgow so if you come North of the border I will be there!

The guinea pigs are still thin, the itchy one is still itchy and the fungal culture is negative at 2 wks so may just have to bite the bullet and get them in for OVH

Hi Mark,

I would probably do midline just because I've never done it another way! And no hyperthyroidism would never have entered my head!!

Yes I would too

And if you are doing a ga anyway take some blood. My app shows the cranial vena cava approach.

Hyperthyroidism is more and more recognised. We are seeing lots.

BTW have you considered hyperthyroidism for the weight loss?

The flank approach is great in young animals - overectomy. In older guinea pigs I don't like it as the approach has to be enlarged and the individual tissue layers do not appose adequately. Based on this, wound secretion arises and in principle the need for a drain. Furthermore, most older guinea pigs with ovarian cysts show uterine patghology. However, the uterus can not be visualised or fully resected via this approach. So for older pigs with cysts I prefer a midline approach.

Goodluck

1. Ovarian cysts won't directly cause weight loss but the space they take up can limit stomach/caecum filling and reduce intake. Pruritus often affects guinea pigs quite severely and may impact on feeding too, is there is significant inflammation that can be a big drain on the reserves of a small animal too.

2. See what happens with skin first as better to assess each problem separately and this will be easier if the skin issue can be resolved. If lice are the sole clinical issue then an ivermectin spray will work better as lice are surface debris feeders and the systemic preparations take ages to reach this section of skin and so tend to be poorly effective.

3. I tend to advise ovariectomy alone for cysts as even if asymptomatic they can progress or induce further changes (uterine hyperplasia/neoplasia/dermatological symptoms/compression of GIT or bladder) and lacking overt symptoms doesn't necessarily mean lacking discomfort in guinea pigs! A bilateral flank approach is simple surgically and is better tolerated by guinea pigs than a large midline incision.
