Secondary prevention

Secondary prevention strategies following amoebic liver abscess include:

• The secondary prevention of amoebic liver abscess includes long-term follow-up after treatment.
• Ultrasound is the main imaging technique used during the follow-up period. The mean time for the disappearance of sonographic features (hypoechoic lesions) is 6-9 months.
• The patterns of resolution on follow-up include:

• Type I: where complete disappearance of the cavity occurs within 3 months (29.8%)
• Type II: a rapid reduction till 25% of the original cavity size and then a delayed resolution (5.9%)

• Factors influencing healing time include:

• The size of abscess cavity on admission
• Anemia
• Hypoalbuminemia
