Prolapsed
Oviduct |
| Disease Agents |
- Usually associated with egg binding, may also occur with normal egg
laying if the oviduct is weak.
- Malnutrition, salpingitis, cloacitis and abnormal eggs (deformed,
soft-shelled, shell-less) may predispose to the development of a prolapse.
- Young, overweight birds are more likely to develop a prolapse (P4.1992.w1).

| General Description |
Prolapsed
cloaca/oviduct visible externally. May contain an egg. Initially smooth, glistening
and pink; soon becomes oedematous and congested and if untreated becomes dry and
eventually necrotic (B13.19.w12, B14, B16.19.w1). |
| Further Information |
N.B. cloacal
prolapse may contain not only oviduct but also ureters and/or intestine. Treatment:
- Gentle cleaning and moistening with normal saline, removal of egg, if
present, repair of any lacerations, application of topical anti-inflammatory preparation
(e.g. steroid/antibiotic preparation or dimethyl sulphoxide gel) to reduce swelling,
lubrication and manual manipulation and replacement.
- A purse-string suture around the vent may be required to prevent the
condition recurring. N.B. This must be placed accurately at the
muco-cutaneous junction to avoid damage to the ureters or nerves (B14).
- Alternatively, two mattress sutures may be used, one placed each side of
the vent.
- Xylocaine gel, applied twice daily, may be used to reduce post-operative
straining.
N.B. :
- Debridement may be required with adhesions or shell abnormalities in
chronic cases.
- Partial or complete hysterectomy may be required if tissue damage is
severe or necrosis has occurred; stabilization of the bird's condition is recommended
prior to such surgery.
