Pain syndrome
Patients most frequently complain of pressure and a feeling of heaviness in the right upper quadrant. Pathogenetically, four variants of pain development are distinguished:
- Stretching of Glisson's capsule. Associated with organ enlargement (hepatomegaly). A typical example is blood congestion in heart failure (cardiac fibrosis or cirrhosis develops).
- Peritoneal irritation (peritoneal pain). Observed in perihepatitis (tumors, abscesses involving the capsule) or pericholecystitis. The pain is intense, radiates upward to the right shoulder, and sharply intensifies upon palpation of the right upper quadrant.
- Biliary tract pathology. Smooth muscle spasm during calculus passage causes biliary (hepatic) colic—unbearable, sudden pain radiating upward. Dyskinesia (motility disorder) or chronic inflammation (cholecystitis) causes dull, aching pain. Specific signs of cholecystitis include tenderness at the gallbladder point (intersection of the costal margin and the lateral border of the rectus abdominis muscle) and a positive phrenic nerve sign.
- Concomitant gastrointestinal pathology. Pain may be caused by concomitant peptic ulcer disease or chronic pancreatitis.
Dyspepsia and abdominal manifestations
Specific complaints are often associated with bile reflux into the upper parts of the digestive tract (gastroesophageal and duodenogastric reflux):
- Dyspeptic disorders. Characterized by an unpleasant, often bitter taste in the mouth, persistent nausea, and belching. Vomiting is a frequent symptom, with fried or fatty foods serving as a triggering factor. An important diagnostic criterion: in biliary colic, vomiting does not bring relief to the patient.
- Stool disorders. Pronounced flatulence is observed, as well as alternating diarrhea and constipation.
- Abdominal changes. The accumulation of free fluid in the abdominal cavity (ascites) manifests as patient complaints of rapid abdominal girth increase and unexplained weight gain.
Jaundice and pruritus
Impaired bile outflow (intrahepatic or extrahepatic bile duct obstruction) leads to the development of cholestasis syndrome and striking manifestations:
- Pruritus (pruritus cutaneus). Can reach extreme severity. It deprives the patient of rest as it significantly intensifies at night, leading to insomnia. Examination reveals objective traces—multiple scratch marks (excoriations)—which carry a direct risk of secondary skin infection.
- Jaundice (icterus). When taking a history, it is important to question the patient in detail about the dynamics of development (onset time and rate of progression) and concomitant abdominal symptoms (pain, nausea, anorexia). Systemic manifestations are also assessed: the presence of fever, chills, and weight loss. An epidemiological history is mandatory to identify the risk of parenteral infection transmission (blood transfusions, tattoos).
General somatic disorders and encephalopathy
Complaints of "general malaise" in liver pathology have a strict pathophysiological basis—impaired detoxification function and toxin accumulation. This leads to central nervous system damage and the development of hepatic encephalopathy.
- Initial manifestations. The patient complains of decreased appetite, cephalalgia (headache), unexplained fatigue, and constant irritability.
- Increasing intoxication. A characteristic sleep inversion occurs: irresistible daytime drowsiness paradoxically combines with nighttime insomnia.
- Severe stage. The extreme degree of syndrome development is hepatic coma (complete loss of consciousness).
In addition to neurological symptoms, patients often note endocrine disorders, such as persistent dysmenorrhea and a significant decrease in libido or potency.
Gastrointestinal bleeding
The appearance of blood is a formidable complication, primarily associated with blood stasis in the portal venous system. Portal hypertension triggers variceal veins and trophic changes in the mucous membrane, leading to hemorrhages.
- Hematemesis (haematemesis). The appearance of unaltered bright red blood in vomit indicates ruptured esophageal varices or acute erosive gastritis.
- Melena. Black, tarry stools indicate upper gastrointestinal bleeding. Causes may include alcoholic gastritis, erosive esophagitis, or Mallory–Weiss syndrome (tears of the esophageal and gastric mucosa during intense vomiting).
- Hematochezia. Bright red blood in the stool is a characteristic sign of hemorrhoidal bleeding.
Briefly: answers to topical questions
What is the phrenic nerve sign and how is it tested for in cholecystitis?
The phrenic nerve sign in chronic gallbladder inflammation (cholecystitis) is a specific pain point: tenderness upon palpation between the heads of the right sternocleidomastoid muscle. Chronic cholecystitis is also characterized by aching or dull pain in the right upper quadrant.
What is the pathogenesis of ascites development in hepatobiliary system diseases?
The pathogenesis of ascites in liver cirrhosis consists of two main links and additional factors.
- Portal hypertension leads to the engorgement of hepatic sinusoids, increased pressure in intrahepatic lymphatic vessels, and fluid transudation through the liver capsule into the abdominal cavity.
- Splanchnic arterial vasodilation causes a hyperdynamic circulation type, peripheral organ hypoperfusion, and reduced effective blood volume.
Compensatory mechanisms worsening ascites:
- Activation of vasoconstrictors (RAAS, sympathetic nervous system, vasopressin secretion) leads to sodium and water retention.
- Impaired hormone catabolism in the liver leads to increased serum concentrations of renin, aldosterone, angiotensin, and vasopressin.
- Hypoalbuminemia reduces plasma oncotic pressure, contributing to the accumulation of free fluid.
To remember the features of biliary colic, use the 4 S's rule: Sudden, Spreading (radiation), Sick stomach (vomiting), but without Soothing (does not bring relief).
Class and exam questions
What is the characteristic feature of vomiting in biliary colic?
Unlike many other gastrointestinal diseases, vomiting in biliary colic does not bring relief to the patient.
How does sleep change in hepatic encephalopathy?
Hepatic encephalopathy is characterized by sleep inversion: the patient suffers from irresistible drowsiness during the day and struggles with insomnia at night.
Why does the right upper quadrant hurt in heart failure?
Due to blood stasis, the liver increases in size (hepatomegaly occurs). This leads to stretching of the organ's Glisson capsule, which causes the pain.
