From Bleeding to Uterine Perforation: Recognizing Intraoperative Risk During Hysteroscopy

Why bleeding and perforation are closely linked

The uterine cavity is small, and visualization depends on controlled fluid distension. If an instrument enters too deeply or deviates from the cavity, the myometrium and uterine vessels may be injured. Bleeding can rapidly obscure the operative field, while a perforation may be associated with intra-abdominal hemorrhage or injury to surrounding organs. For that reason, the two complications are often assessed together.

Patients who require additional caution

Cervical stenosis, postmenopausal cervical changes, previous cervical or uterine surgery, pronounced uterine flexion, a small cavity, and lesions near the cornua or lateral wall may increase technical difficulty. Cesarean scar lesions, coagulation disorders, abnormal vascular conditions, and pregnancy-related tissue invasion can increase bleeding risk. Defining anatomy, lesion depth, and vascularity before surgery helps the team prepare an appropriate monitoring and hemostasis plan.

Early recognition is more valuable than late rescue

Possible warning signs include sudden loss of cavity distension, an unexpectedly open view or visualization of tissue outside the uterus, a marked discrepancy in irrigation-fluid recovery, free fluid on ultrasound, or changes in the patient's circulation. The use of an energized instrument, the location of injury, and the possibility of bowel or bladder involvement all affect urgency. Temporary hemodynamic stability alone does not exclude a significant injury.

Management is based on severity and mechanism

When perforation or major bleeding is suspected, intrauterine manipulation is stopped while the team evaluates blood loss, injury location, energy use, and vital signs. A small non-energized injury without active bleeding may sometimes be managed with close observation. Lateral or lower uterine injuries, persistent bleeding, or possible visceral damage may require laparoscopy or laparotomy for inspection, hemostasis, and repair. Other surgical specialists should be involved promptly when an adjacent organ may be affected.

Prevention lives in the details

Appropriate cervical preparation, gentle dilation, confirmation of uterine direction, continuous visualization, controlled tissue depth, and ultrasound or laparoscopic guidance in complex cases can reduce risk. After surgery, ongoing assessment of pain, vaginal bleeding, blood pressure, heart rate, and laboratory findings helps identify delayed hemorrhage or an injury that was not apparent during the procedure.
