==Introduction==
Prolapse through the vent can be quite common in fish. This can occur secondary to an '''infective process''' or due to '''straining from passing eggs''' or constipation.

Potential prolapsed organs include:

:'''cloacal prolapse''' through the anal pore
:'''intestinal prolapse''' through the anal pore
:'''rectal prolapse''' through the anal pore
:intestinal prolapse through the genital pore
:'''ovarian prolapse''' through the genital pore

==Clinical Signs==
The most obvious clinical sign will be of a '''mass''' protruding from the vent of the fish.

The fish may appear depressed, lethargic and anorexic. [[Dropsy]] may occur.

==Diagnosis==
The nature of the prolapse may become apparent after a '''careful physical examination'''.

Intestine will have a '''smooth surface''' whereas ovarian tissue appears grainy with small white to yellow follicles.

'''Cytology''' may help differentiate the tissue and provide a definitive diagnosis.

==Treatment==
In the case of ovarian tissue, '''surgical resection''' is recommended. An encircling ligature can be placed or a CO2 laser can be used to remove the mass. Further eggs can be milked from the fish by inserting a syringe into the genital pore and exerting pressure on the fish's abdomen.

Prolapsed intestine or rectum should be '''reduced''' if possible, and suture material can be used to anchor the tissue to the vent.

'''Conservative treatment''' is also possible and some prolapses reduce on their own if the fish is in otherwise good condition.

A '''purse-string suture''' can be placed around the genital pore or the anal pore to prevent further prolapses whilst also allowing the passage of eggs or faeces.

Care should be taken to provide optimum water quality and to avoid unnecessary stress to the fish.
