Ultrasonography guidance for total splenectomy in donkeys.

Abstract: There are varieties of surgical approaches reported for equine splenectomy and all of them were dealing with the most reachable situation of splenic hilus and easy handling of the spleen. The aim of this work was to establish the normal ultrasound parameters of spleen in donkeys (normal echogenicity, hilus situation, topographic location and correlation with neighboring organs) as a guide to select the best approach for total splenectomy in donkeys. Splenic ultrasound was carried out on six normal donkeys before experimental total splenectomy in the standing position. The splenic topographic location was recorded among 4 rows including 30 squares. These animals were divided into two groups according to the surgical approach of total splenectomy. Total splenectomy after left 16 and 17 ribs partial resection in standing position was carried out in group1 and group 2, respectively. Ultrasonographically, the spleen had homogenously echogenic pattern and appeared hyperechoic to the liver. Only one third of the spleen was located in front of the 16 rib where the hilus and splenic blood vessels were nearly under the 16 rib. The splenic artery and splenic vein were ultrasonographically visualized between the left 16 and 17 ribs 10-15 cm from dorsal midline. This area was the site of the important ligation during total splenectomy. In conclusion, ultrasonography guidance for total splenectomy in donkeys assisted the surgical findings and proved that technique following partial resection of the 17 rib at the standing position is the most convenient surgical approach for total splenectomy in donkeys.

The study examines the use of ultrasonography in guiding surgical approaches to completely remove the spleen (total splenectomy) in donkeys. The researchers focus on how this method can help to identify the spleen’s normal location and relationship with nearby organs, assisting in choosing the most efficient surgical technique.

Research Setup

  • Initially, the research was conducted on six healthy donkeys.
  • For these donkeys, the ultrasonographic parameters of a healthy spleen, including its normal echogenicity (capability to echo sound waves), situation of the hilus (the point where blood vessels enter an organ), topographic location, and the relationship with surrounding organs, were established.
  • The position of the spleen within the animal’s body was mapped across 30 squares and four rows for a detailed understanding of its geographic placement.
  • The participants were split into two groups based on the surgical path adopted for total splenectomy.

Results & Surgical Technique

  • The ultrasound showed a uniformly reflective or ‘echogenic’ pattern on the spleen.
  • The spleen appeared brighter or ‘hyperechoic’ compared to the liver.
  • Only a third of the spleen was positioned in front of the 16th rib, with the hilus and the splenic vessels almost below this rib.
  • The splenic artery and vein were visualized between the left 16th and 17th ribs 10-15 cm from the dorsal midline, which was the crucial location for ligation during the splenectomy.
  • These findings indicated that the most effective surgical approach for a complete spleen removal in donkeys was through partial resection of the 17th rib while the animal was standing.

Conclusion

  • The findings support the hypothesis that ultrasonography guidance can aid in determining the optimal surgical methodology for total splenectomy in donkeys.
  • The surgical technique following partial resection of the 17th rib in the standing position was found to be the most convenient and efficient approach.
