Differential Diagnosis for Constipation and Tender Chest Pain in a Patient with Cirrhosis and Right Bundle Branch Block

Single Most Likely Diagnosis

  • Spontaneous Bacterial Peritonitis (SBP) with Refractory Ascites: This condition is a common complication in patients with cirrhosis, especially those with ascites. The constipation could be related to the use of medications such as lactulose for hepatic encephalopathy, which is often seen in cirrhotic patients. The tender chest pain might be referred pain from the abdominal cavity due to the peritonitis.

Other Likely Diagnoses

  • Gastroesophageal Reflux Disease (GERD): Patients with cirrhosis can have an increased risk of GERD due to factors like ascites, which can increase intra-abdominal pressure. GERD can cause chest pain and discomfort, potentially exacerbated by constipation.
  • Hepatic Hydrothorax: This condition involves the accumulation of fluid in the pleural space in patients with cirrhosis. It can cause chest pain and could potentially be related to constipation through mechanisms like increased intra-abdominal pressure.
  • Cardiac Causes (e.g., Ischemia): Although the patient has a right bundle branch block, which might suggest some cardiac abnormality, the presence of cirrhosis and its complications makes cardiac ischemia less likely but still a consideration, especially given the chest pain.

Do Not Miss Diagnoses

  • Pulmonary Embolism: Although less likely, pulmonary embolism is a critical diagnosis to consider due to its high mortality rate. Patients with cirrhosis can have a hypercoagulable state, increasing their risk for thromboembolic events.
  • Myocardial Infarction: Despite the presence of a right bundle branch block, myocardial infarction must be considered, especially with chest pain, as the ECG changes can be masked or atypical.
  • Spontaneous Hemorrhage (e.g., Hemoperitoneum): In patients with cirrhosis, spontaneous hemorrhage into the peritoneal cavity can occur, especially in the setting of coagulopathy, and could present with abdominal pain potentially referred to the chest.

Rare Diagnoses

  • Hepatopulmonary Syndrome: A rare condition in patients with cirrhosis, characterized by pulmonary vascular dilatations leading to hypoxemia. It could potentially cause chest discomfort but is less directly related to constipation.
  • Constrictive Pericarditis: Although rare, it can cause chest pain and could be a consideration in patients with cirrhosis who have had previous pericardial disease or other conditions leading to pericardial scarring.
