Post-splenectomy complications

Every organ in the human body plays a vital role; therefore, removal of certain organs may lead to specific postoperative complications. What complications can occur after splenectomy?

Complications Following Splenectomy

Potential complications after splenectomy include impaired immune function, elevated platelet counts, and enhanced coagulation. When immune function declines, patients become more susceptible to various infectious diseases—particularly respiratory infections—whose incidence increases significantly. For example, patients may experience recurrent colds, tonsillitis, or bronchitis. Elevated platelet counts and heightened coagulability predispose patients to thrombosis, thereby increasing the risk of thromboembolic disorders. However, these adverse effects typically occur only within the first six months following splenectomy.

The spleen is an intra-abdominal organ playing crucial roles across multiple systemic functions—including digestion, immunity, and hematopoiesis. Located directly beneath the left side of the thoracic cavity and adjacent to the stomach, the spleen significantly influences normal gastric function. It stores large numbers of stress-responsive white blood cells and serves as a major source of antibodies. Beyond its roles in pathogen defense and phagocytosis, the spleen also promotes wound healing.

Within the hematologic system, the spleen clears, breaks down, and metabolizes aged red blood cells; recycles and stores iron for new red blood cell production; and rapidly releases stored blood components during hemorrhage. Thus, it plays a critical role in regulating and maintaining circulating blood volume. We hope this information is helpful to you!
