Abdomen: adhesion formation - post-surgical

Clapis

Introduction

  • Rabbits are well known for their propensity to form adhesions after surgery in the coelomic cavity.
  • They are widely used as animal models for research on intra-abdominal adhesions.
  • Cause: inflammation of tissues within abdominal cavity.
  • Signs: abdominal discomfort, lethargy, reduced appetite/anorexia, reduced fecal output/diarrhea.
  • Diagnosis: clinical assessment, radiography, ultrasound, abdominal fluid, surgery or endoscopy.
  • Treatment: surgical resection.
  • Prognosis: depends on the location of the adhesions.

Presenting signs

  • May be acute or chronic in onset.
  • Reduced appetite.
  • Lethargy.
  • Reduced fecal output (gastrointestinal stasis).
  • Chronic diarrhea.
  • Abdominal discomfort.
  • Bruxism.

Acute presentation

  • Anorexia.
  • Gastrointestinal stasis with cessation of fecal output.
  • Abdominal distension.
  • Abdominal pain.
  • Bruxism.

Cost considerations

  • Repeated surgery to attempt resolution may be expensive.

Special risks, eg anesthetic

  • Prolonged surgery time may be associated with more extensive handling of abdominal viscera, thus increasing the risk of post-operative adhesion formation.
