Summary
In dogs and cats, 21% of diagnostic laparoscopies required conversion to celiotomy. Key risk factors for conversion included solitary liver tumors, low total solids, and a neoplasia diagnosis.
Area of Science:
- Veterinary Surgery
- Minimally Invasive Procedures
- Surgical Oncology
Background:
- Diagnostic laparoscopy is increasingly used in veterinary medicine.
- Conversion to celiotomy during laparoscopic procedures can occur.
- Understanding predictors of conversion is crucial for surgical planning.
Purpose of the Study:
- To identify reasons for conversion from diagnostic laparoscopy to celiotomy in dogs and cats.
- To assess risk factors associated with conversion during laparoscopic procedures.
Main Methods:
- A case series review of medical records from 2004-2008.
- Analysis of 94 dogs and cats undergoing diagnostic laparoscopy or laparoscopic-assisted biopsy.
- Statistical analysis including chi-squared, Fisher's exact, t-tests, Wilcoxon's rank-sum, and logistic regression.
Main Results:
- Twenty animals (21%) required conversion to laparotomy.
- Elective conversions (65%) were more common than emergent ones (35%).
- Significant risk factors for conversion included solitary liver tumors, low total solids, and a diagnosis of neoplasia.
Conclusions:
- The conversion rate for diagnostic laparoscopy in this cohort was 21%.
- Preoperative findings of solitary liver tumors, low total solids, and malignancy are significant risk factors for conversion.
- These findings aid in predicting and managing laparoscopic-to-celiotomy conversions in veterinary patients.
