Summary
Patients undergoing distal pancreatectomy with splenectomy (DPS) show increased blood clotting long-term compared to spleen-preserving procedures (SPDP). Further research is needed to link this hypercoagulability to clinical events after splenectomy.
Area of Science:
- Surgical Oncology
- Gastroenterology
- Hematology
Background:
- Short-term outcomes of spleen-preserving distal pancreatectomy (SPDP) and distal pancreatectomy with splenectomy (DPS) are comparable.
- Long-term data on thrombotic and infectious risks following splenectomy are limited.
- The study investigates differences in coagulation status after SPDP versus DPS.
Purpose of the Study:
- To compare the long-term coagulation status of patients after SPDP and DPS.
- To determine if differences in coagulation status after splenectomy have clinical significance.
Main Methods:
- Follow-up of 41 patients who underwent distal pancreatectomy (20 SPDP, 21 DPS).
- Assessment of coagulation and immune status alterations.
- Utilized global coagulation tests, multiple platelet function analyzer, and rotational thrombelastography.
Main Results:
- Patients after DPS exhibited a significantly higher tendency for platelet aggregation and coagulation activation compared to SPDP patients.
- No septic or thromboembolic events were observed in either group during the study period.
Conclusions:
- Splenectomized patients demonstrate persistent hypercoagulability years after surgery.
- A large cohort study is recommended to correlate long-term hypercoagulability with thromboembolic events and mortality post-splenectomy.
