Hemoperitoneum: Symptoms, Types, Causes and Treatment

Hemoperitoneum—bleeding into the peritoneal cavity—is a critical condition that can rapidly become life-threatening. This article provides an evidence-based overview of its symptoms, types, causes, and treatment approaches, drawing from a wide range of clinical and research sources. Whether triggered by trauma, disease, or medical procedures, understanding hemoperitoneum is essential for timely recognition and intervention.

Symptoms of Hemoperitoneum

Recognizing the symptoms of hemoperitoneum can be the difference between life and death. While the presentation varies depending on the underlying cause, the rapid accumulation of blood in the abdomen often provokes a dramatic set of signs and symptoms. Awareness of these early indicators is key for patients, caregivers, and healthcare professionals alike.

Symptom	Description	Severity	Source(s)
Abdominal Pain	Sudden, severe, diffuse	Often intense	1 2 4 7 9
Abdominal Distension	Swelling or fullness	Variable	9
Shock	Hypotension, tachycardia	Life-threatening	1 2 8 9
Anemia Signs	Pallor, weakness, dizziness	Mild to severe	9
Nausea/Vomiting	Sometimes present	Mild	2 7

Table 1: Key Symptoms

Abdominal Pain and Tenderness

Abdominal pain is the most common and often the earliest symptom of hemoperitoneum. It's typically sudden in onset and can be severe. The pain may be diffuse or localized, depending on the source of the bleeding. Physical examination often reveals tenderness and guarding, with possible rigidity as the bleeding progresses 1 2 4 7 9.

Abdominal Distension

As blood accumulates, the abdomen may become visibly distended. This can happen rapidly in cases of massive bleeding or more gradually with slower hemorrhage. Distension is sometimes accompanied by a feeling of fullness or bloating 9.

Signs of Shock

Large-volume blood loss can quickly lead to hypovolemic shock. Early signs include a rapid heartbeat (tachycardia), low blood pressure (hypotension), cold and clammy skin, and confusion. Notably, blood pressure can remain normal in the initial stages, particularly if the bleeding is slow, so repeated measurements are crucial 1 2 8 9.

Symptoms of Anemia

With ongoing blood loss, symptoms of anemia such as pallor, weakness, dizziness, and shortness of breath may develop. Acute anemia may cause patients to feel faint or experience chest discomfort, especially if the bleeding is substantial 9.

Nausea and Vomiting

Some patients report nausea or vomiting, either as a direct response to peritoneal irritation or as part of the body's response to shock. While not specific to hemoperitoneum, these symptoms may appear in the acute setting 2 7.

Types of Hemoperitoneum

Hemoperitoneum is not a single disease entity but rather a clinical syndrome with diverse etiologies. Understanding the types can help guide both diagnosis and management, as different causes often demand distinct responses.

Type	Etiology Category	Typical Scenario	Source(s)
Traumatic	Physical injury	Blunt or penetrating trauma	4 10
Nontraumatic	Medical disease	Tumor, vascular, coagulopathy	4 6 7 8
Spontaneous	No obvious trigger	Rupture of varix, tumor, cyst	2 6 7 8
Iatrogenic	Medical intervention	Post-surgery, procedures	1 4 8

Table 2: Main Types of Hemoperitoneum

Traumatic Hemoperitoneum

This is the most common type and results from blunt or penetrating trauma to the abdomen. Injuries to solid organs such as the liver or spleen are frequent culprits. Traumatic hemoperitoneum can be detected on imaging (CT, ultrasound) and often requires emergency intervention 4 10.

Nontraumatic Hemoperitoneum

Nontraumatic cases occur without an external injury and are associated with disease processes such as tumors, vascular malformations, and coagulopathies. For example, hepatocellular carcinoma, ovarian cyst rupture, or splenic disease can all cause nontraumatic bleeding 4 6 7 8.

Spontaneous Hemoperitoneum

Spontaneous hemoperitoneum occurs when bleeding arises without a clear precipitating event. This may be due to a sudden rupture of a blood vessel, varix, or intra-abdominal tumor. Gynecologic causes, such as ruptured ectopic pregnancies or ovarian cysts, are notable subtypes 2 6 7 8.

Iatrogenic Hemoperitoneum

Sometimes, hemoperitoneum is a complication of medical interventions—surgical procedures, biopsies, or therapeutic paracentesis. In patients with liver disease and portal hypertension, paracentesis can precipitate variceal rupture and acute bleeding 1 4 8.

Causes of Hemoperitoneum

The causes of hemoperitoneum are diverse, spanning trauma, disease, and medical interventions. Knowing these causes is critical for risk assessment and prevention, as well as for directing diagnostic and therapeutic efforts.

Cause Category	Specific Example	Population at Risk	Source(s)
Trauma	Liver/spleen injury	All, esp. young adults	4 10
Tumors	Hepatocellular carcinoma	Cirrhotics, elderly	8 9 11
Vascular	Ruptured aneurysm/varices	Elderly, hypertensives	1 2 4 6 8
Gynecologic	Ectopic pregnancy, cysts	Women of reproductive age	4 5 6 7
Coagulopathy	Hemophilia, anticoagulants	Patients on blood thinners	4 7
Iatrogenic	Surgery, paracentesis	Hospitalized patients	1 4 8
Peritoneal dialysis	Dialysis-related bleeding	Renal failure patients	3

Table 3: Major Causes of Hemoperitoneum

Traumatic Causes

• Blunt trauma: Motor vehicle accidents, falls, and sports injuries can cause lacerations to abdominal organs, leading to rapid bleeding.
• Penetrating trauma: Stab or gunshot wounds may directly damage blood vessels or organs 4 10.

Tumor-Related Bleeding

• Hepatocellular carcinoma (HCC): Spontaneous rupture of liver tumors is a recognized cause, especially in patients with cirrhosis 8 9 11.
• Other tumors: Ovarian carcinoma and metastatic liver disease may also result in hemoperitoneum, particularly if the tumor invades or erodes blood vessels 4 8.

Vascular and Variceal Rupture

• Aneurysms: Rupture of abdominal arteries, such as the superior mesenteric artery, can produce massive bleeding 2 4 6.
• Varices: In portal hypertension, varices (dilated veins) can rupture, sometimes after procedures like paracentesis, leading to catastrophic hemoperitoneum 1 2 8.

Gynecologic Etiologies

• Ectopic pregnancy: Rupture of a tubal pregnancy is a leading cause of hemoperitoneum in women of reproductive age 4 5 6 7.
• Ovarian cyst rupture: Particularly in women on anticoagulation therapy or with polycystic ovarian syndrome.
• Endometriosis: May increase the risk of spontaneous hemoperitoneum during pregnancy 5.

Coagulopathies and Blood Disorders

• Inherited: Hemophilia increases bleeding risk.
• Acquired: Use of anticoagulant medications, blood dyscrasias (e.g., polycythemia vera), and liver failure impair clotting and predispose to bleeding 4 7.

Iatrogenic and Dialysis-Related

• Procedural: Surgeries, abdominal interventions, or paracentesis can inadvertently cause bleeding.
• Dialysis: Chronic peritoneal dialysis, especially in women, can result in hemoperitoneum, sometimes due to menstruation, ovulation, or peritoneal membrane changes 1 3 4 8.

Treatment of Hemoperitoneum

Timely treatment of hemoperitoneum is crucial to survival. Management strategies are dictated by the cause, severity, and overall condition of the patient. The principles involve stabilizing the patient, stopping the bleeding, and treating underlying conditions.

Treatment Modality	Purpose	Common Scenario	Source(s)
Fluid Resuscitation	Restore blood volume	All acute cases	10 11
Blood Transfusion	Correct anemia/shock	Severe cases	10 11
Surgery	Definitive bleeding control	Trauma, tumor rupture	1 2 10 11
Interventional Radiology	Embolization/TIPS	Tumor, variceal rupture	1 9 11
Medical Management	Manage coagulopathy	Mild/moderate cases	3 10

Table 4: Key Treatments for Hemoperitoneum

Initial Stabilization

• Airway, Breathing, Circulation: First priorities include ensuring the airway is protected, supporting breathing, and restoring adequate circulation.
• Fluid resuscitation: Intravenous fluids are started promptly to replace lost volume.
• Blood transfusion: If there is significant blood loss or evidence of shock, transfusion of packed red blood cells is needed 10 11.

Identifying and Controlling the Bleed

• Imaging: CT scans, ultrasound, and sometimes diagnostic peritoneal lavage help identify the source and extent of bleeding 4 7.
• Definitive control:
  • Surgery: Often required for traumatic injuries, intra-abdominal tumors, or when less invasive measures fail. Surgical techniques may involve ligation of bleeding vessels, resection of ruptured tumors, or repair of organ injuries 1 2 10 11.
  • Interventional radiology: Procedures like transcatheter arterial embolization (TAE) or transjugular intrahepatic portosystemic shunt (TIPS) can control bleeding from tumors or varices, particularly in high-risk surgical candidates or in cases of portal hypertension 1 9 11.

Treating Underlying Conditions

• Coagulopathy correction: Administration of clotting factors, platelets, or reversal of anticoagulants may be necessary 3 10.
• Gynecologic management: For ectopic pregnancy or ruptured ovarian cyst, gynecologic surgery may be needed 4 5 7.
• Dialysis patients: Address any underlying peritoneal membrane pathology or adjust dialysis technique if recurrent bleeding occurs 3.

Monitoring and Supportive Care

• Frequent reassessment: Monitor vital signs, hemoglobin, and coagulation status.
• ICU care: Severely ill or unstable patients may require intensive monitoring and support 10 11.
