Species: Feline | Classification: Techniques
- Access to abdominal cavity (infrequently in the USA).
- Treatment of various lesions, eg kidney stones Urolithiasis, gastric FBs.
- Investigation if other options unavailable or inconclusive.
- Gastrotomy tube placement Gastrostomy: percutaneous tube (endoscopic).
- Gastric decompression.
- Ovariohysterectomy - unless possible coat color change at site may be unacceptable to owner, or large exposure indicated Ovariohysterectomy.
- Adrenal surgery (primarily in the USA).
- Kidney biopsy.
- Muscle splitting approach may reduce risk of dehiscence if tissue healing poor.
- Good unilateral access to organs placed dorsally in the abdomen.
- Limited access to restricted areas.
- Hair regrowth at site may be darker in color - this may be unacceptable to some owners, eg in show animals - ventral midline approach may be a suitable alternative.
Criteria for choosing test
- Midline laparotomy is usually preferred technique since it allows a full assessment of abdominal organs.
- Standard kit Surgical instruments.
- Fast patient for 12 hours before to avoid reflux esophagitis Esophagitis.
- General anesthesia General anesthesia: overview.
- Occasionally performed under sedation and infiltration with local anesthetic.
Step 1 - Position patient
- Lateral recumbency, (left or right according to access required).
Step 2 - Incise skin
- Vertical skin incision extending dorsally or ventrally according to exposure required.
Step 3 - Blunt dissection of muscles
- Open each muscle layer by blunt dissection in direction of fibers.
- Further surgery depends on core procedure.
Step 1 - Close muscle layers
- Close muscle in layers using monofilament nylon, polypropylene, polygalactin, polydioxanone or chromic catgut using a simple continuous pattern.
Suturing peritoneum may increase risk of adhesions.
Step 2 - Close skin
- Routine skin closure.
- Essential Analgesia: overview.
