Indications.
1, abdominopelvic abscesses that can be revealed by ultrasonography and where antibiotic treatment is less effective
2. Those with a safe puncture route
Contraindications.
1, those whose lesions cannot be confirmed by ultrasonography or whose sonograms are unclear, and those without a safe puncture route
2.Severe bleeding tendency, bleeding and coagulation mechanism disorders
3. Pre-liquefaction or inadequate liquefaction of liver abscess
4. Those who cannot exclude aneurysm or hemangioma combined with infection
5.With another indication for emergency dissection
The proposed ultrasound-guided puncture and drainage of liver abscess may present
1.Hepatic hemorrhage
2.Biliary tract injury
3, abdominal infection, peritonitis
4.Thoracic infection, abscess chest
5.Repeated treatment possible
6.Postponed re-operation possible

Technical points.
1.For retroperitoneal abscess, the tube should not be inserted from the anterior abdominal wall but from the lateral abdomen or lumbar back to avoid passing through the peritoneal cavity
2. If a cold abscess due to tuberculosis is suspected, only diagnostic aspiration should be performed, and cannulation should not be done to drain the abscess
