Laparoscopic partial splenectomy in distal pancreatectomy may preserve splenic function

Area of Science:

• Surgical Oncology
• Immunology
• Gastroenterology

Background:

• Splenectomy increases infection risk from encapsulated organisms.
• Current guidelines mandate extensive vaccination and antibiotics post-splenectomy.
• Distal pancreatectomy (DP) often necessitates splenectomy.

Purpose of the Study:

• To evaluate the feasibility of partial splenectomy during DP.
• To assess if partial splenectomy preserves splenic function and immunocompetence.
• To offer an alternative to complete splenectomy in select cases.

Main Methods:

• Laparoscopic distal pancreatectomy with partial splenectomy (LDPPS) performed on five patients.
• Resection of the inferior spleen en bloc with the pancreas.
• Utilized ligasure and linear cutting staplers for splenic transection.
• Managed blood loss by temporarily clamping short gastric vessels.

Main Results:

• Successful laparoscopic LDPPS in all five patients within 4 hours.
• Pathologies included benign and malignant pancreatic lesions.
• No blood transfusions required; one patient had a minor postoperative collection.
• Imaging and blood films confirmed perfused splenic remnants and retained function post-surgery.

Conclusions:

• Partial splenectomy is a feasible option during DP.
• Preserving splenic tissue may maintain immunocompetence.
• This technique offers potential long-term advantages over complete splenectomy.
