Vascular injuries are not rare in gynecologic oncologic surgery,1 and proper bleeding management is critical to ensure successful outcomes and minimize the risk of complications (Video 1).
The management of bleeding during gynecologic oncologic surgery begins with a thorough pre-operative evaluation. Surgical anatomy is crucial, and knowing that some major vessels can be ligated—including the left renal vein2—is important in catastrophic situations. It is important to understand all bleeding control options, including that ligation may be a better option than repair in some situations.3 Patients who are at increased risk of bleeding, such as those with bleeding disorders or those taking anti-coagulant medications, should be identified and appropriate measures taken to minimize the risk of bleeding. This may involve discontinuing certain medications prior to surgery or administering blood products such as platelets or fresh frozen plasma to correct coagulation abnormalities.
During surgery, meticulous hemostasis is essential. This may involve the use of a variety of techniques including bipolar energy, suturing, clips, and hemostatic agents. In some cases, bleeding may be severe and require vascular clamps or ligatures may be required to control bleeding.2 Transoperative blood transfusions may also be necessary if significant blood loss occurs during surgery.
During minimally invasive surgery, the decision to convert to open surgery depends on factors such as the extent and severity of the bleeding, the underlying cause, and the surgeon’s experience. If the surgeon cannot achieve hemostasis or visualize the surgical field adequately, or if there is a major blood vessel injury, conversion to open surgery may be required. In addition, if the patient’s vital signs become unstable, open surgery may be necessary to control bleeding quickly.
In summary, a thorough understanding of the surgical anatomy is fundamental to identifying the source of bleeding and selecting the best control approach. Compression should be a reflex when there is bleeding (Figure 1), followed by considering calling the vascular surgeon and conversion for control, if necessary. Suturing is the best strategy for preparing external and common iliac vessels, cava and aorta, but clips may be used in highly selected situations. Sutures should only be used with control. Hemostatic agents are adjuvant strategies for controlled bleeding.
