From the Guidelines

There is no indication for follow-up of simple hepatic cysts, regardless of size, as long as they remain asymptomatic. According to the EASL clinical practice guidelines on the management of cystic liver diseases 1, simple hepatic cysts are benign lesions that typically follow an indolent course without significant changes in size over time. The guidelines suggest that if patients become symptomatic, imaging (ultrasound first) will assess the size and look for complications and compression 1. Some key points to consider include:

  • Simple hepatic cysts are fluid-filled sacs in the liver that are generally benign and common, occurring in about 2-7% of the population.
  • They typically grow slowly, if at all, and rarely cause complications.
  • Treatment is usually not necessary unless symptoms develop, in which case drainage or surgical removal might be considered.
  • The decision for follow-up ultimately depends on your specific medical history and should be discussed with your healthcare provider who can tailor recommendations to your individual situation. It is essential to seek medical attention if symptoms such as abdominal pain, nausea, or early satiety develop 1.

From the Research

Follow-up for Simple Hepatic Cyst

  • A 4.1 cm simple hepatic cyst may not require immediate treatment if it is asymptomatic 2, 3.
  • However, if the cyst is causing symptoms such as abdominal discomfort, pain, or digestive issues, treatment may be necessary 2, 4.
  • The American College of Gastroenterology clinical guidelines recommend laparoscopic fenestration for symptomatic simple hepatic cysts due to its high success rate and low invasiveness 2.
  • Percutaneous aspiration or sclerotherapy may also be considered for symptomatic cysts, but these methods have a higher rate of recurrence 2, 4.
  • Regular follow-up with imaging studies such as ultrasound or CT scans may be recommended to monitor the size and characteristics of the cyst 3, 5.
  • If the cyst is large or symptomatic, surgical management such as open hepatic resection or laparoscopic fenestration may be necessary 6.
  • It is essential to differentiate simple hepatic cysts from other cystic lesions, such as biliary cystadenoma, to avoid unnecessary surgery 5.
