New approach to the splenic vessels

Area of Science:

• Surgical Innovation
• Vascular Surgery
• Abdominal Surgery

Background:

• The transperitoneal approach for splenorenal anastomosis is associated with significant morbidity and mortality.
• This traditional method carries risks such as pancreatic damage and complications in cirrhotic patients.

Purpose of the Study:

• To evaluate the efficacy and safety of a retroperitoneal approach for splenorenal anastomosis.
• To present an alternative surgical technique for splenic hilus access.

Main Methods:

• A retroperitoneal approach to the splenic hilus via the lumbar region was developed.
• This method was used for arterial and venous splenorenal anastomoses.
• The technique was applied in 13 cases since 1972.

Main Results:

• The retroperitoneal approach proved less aggressive, avoiding pancreatic damage.
• It offers a more direct route to splenic vessels with improved exposure and anastomosis.
• Complications such as ascitic fluid loss/infection and intraoperative hemorrhage were avoided.
• No mortality or complications were observed in the 13 cases.

Conclusions:

• The retroperitoneal approach is a safe and effective alternative for splenorenal anastomosis.
• This technique reduces surgical risks and improves patient outcomes, particularly in cirrhotic patients.
