Summary
Laparoscopic subtotal splenectomy is a feasible and safe procedure in dogs, with minimal blood loss and normal histological outcomes. This minimally invasive approach offers a reliable alternative for splenic procedures.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Veterinary Surgery
Background:
- Subtotal splenectomy has been utilized since 1979 for various conditions including splenic trauma, portal hypertension, and hematological disorders.
- Laparoscopic techniques offer potential advantages in terms of reduced invasiveness and faster recovery.
Purpose of the Study:
- To evaluate the feasibility, reliability, and safety of laparoscopic subtotal splenectomy.
- To compare outcomes with traditional total splenectomy.
Main Methods:
- A comparative study involving 14 mongrel dogs divided into two groups: laparoscopic subtotal splenectomy and median laparotomy total splenectomy.
- Surgical procedures utilized a linear laparoscopic surgical stapler for splenic sectioning, hemostasis, and closure.
- Post-operative assessments included hematological, immunological, and scintigraphic examinations, along with histological analysis of spleen, liver, and lymph nodes after 3 months.
Main Results:
- All animals survived the procedure and 3-month follow-up with minimal blood loss.
- A statistically significant reduction in platelet count was observed in the laparoscopic subtotal splenectomy group (p<0.05).
- Hematological parameters, histological examination of remnant spleens, livers, and lymph nodes were normal in both groups.
Conclusions:
- Laparoscopic subtotal splenectomy is a feasible and safe surgical option in canine models.
- The procedure demonstrates promising results for splenic tissue preservation and overall patient safety.
