Liver Abscess Percutaneous Drain Placement

Liver abscess percutaneous drain placement

Percutaneous drainage is an invasive procedure minimally invasive to treat liver abscess, where a fine catheter is inserted through the skin into the abscess cavity to remove pus. It is often carried out under ultrasound or CT and is among the effective methods of the treatment of moderate to large abscesses of the liver.

What is Percutaneous Liver Abscess Drain Placement?

• Percutaneous drainage entails the passing of a sterile tube (catheter) through the skin to the abscess of the liver in order to drain it out of infected fluid.
• An interventional radiologist performs it and considerably reduces infection, pain, and fever and avoids such complications as rupture or sepsis.

Indications

Percutaneous drain placement is advised in cases where:

• Abscess size is >3–5 cm
• It has multiloculated abscess.
• Alone failure to respond to antibiotics.
• High fever, pain, or sepsis
• Risk of rupture
• Amoebic or pyogenic abscess not healed.

Liver abscess percutaneous drainage procedure

A small thin tube (pigtail catheter) is inserted through the skin directly into the liver abscess to drain the pus during the procedure. This relieves infection, reduces the fever and pain, and averts complications like rupture, sepsis or spread of infection. 

Preparation before procedure

• Extensive CT scan or ultrasound.
• Blood tests
• IV antibiotics started
• 4-6 hours (when there is need to be sedated) fasting.
• Consent taken
• Patient is lying (mostly lying on his back).
• Skin cleaned and sterilized

Anaesthesia

• Local anaesthesia of puncture site.
• Conscious sedation can be administered to be comfortable.
• General anaesthesia is necessary.

Step-by-Step Procedure

Step 1: Imaging Guidance 

• The abscess can be located by using ultrasound or CT scan.
• The access route selected is the safest one that will not harm blood vessels and bowel.

Step 2: Needle Insertion

• The imaging allows a thin needle to be guided through the skin into the abscess cavity. 
• The pus is aspirated and a part of it is cultured in the laboratory. 

Step 3: Guidewire Placement

• A needle with a guidewire is inserted through the needle into the abscess cavity.
• The needle is set aside keeping the guidewire within it.

Step 4: Tract Dilatation

• The guidewire is widened in the tract by using a dilator.

Step 5: Catheter Placement

• A drainage catheter in the form of a pigtail is introduced into the abscess on top of the guidewire.
• The end of the pigtail twist inwards and it does not slip.
• The catheter leads to a drainage bag.

Step 6: Securing the Catheter

• The catheter is sewed or taped to the skin, so that it will not be moved.
• Sterile dressing is used.
• Total Duration: 30–60 minutes
• Procedure Type: Day-care/short hospital.

Post Procedure (Recovery)

In Hospital

• Monitored Vitals and drain output.
• IV antibiotics continued
• Fever and pain relief would occur in 24-48 hrs, depending on the patient.
• The routine drain care and monitoring.
• Ultrasound can be done again to monitor progress.

Drain Removal

The drain is removed when:

• Production decreases to a great extent.
• Cavity of abscess diminishes as an image.
• Typically it takes 5-10 days, although bigger abscesses may take longer.

At Home

• Keep drain site clean and dry
• Take prescribed antibiotics.
• Take few weeks off heavy lifting.
• 1-2 weeks follow-up ultrasound.

Liver abscess percutaneous drainage recovery

Percutaneous drainage recovery is generally an easy and rapid procedure compared to open surgery. The majority of patients report that they start to feel better with regards to fever, pain and weakness 24-48 hours after catheter insertion.

Recovery in the Hospital

The initial monitoring (First 24-48 Hours) is performed

• Constant observation of blood pressure, pulse, and fever.
• Determining drainage products (color, volume, consistency)
• Evaluation of responsiveness to antibiotics.
• Pain control (mostly mild pain), only.

Drain Care

• In case of catheter blockage, the catheter is flushed.
• The dressing around the drain site is changed on a daily basis.
• The abscess pus is submitted to culture, and the antibiotics can be changed.

Repeat Imaging

• A follow-up ultrasound/ CT scan can be performed to:
• Determine size of abscess reduction.
• Ascertain accurate catheter placement.

Nutrition

• Light diet to be administered when patient is stable.
• IV fluids used to preserve hydration, followed by oral.

Hospital Stay

• Most patients stay 1–3 days
• Large abscesses or severe infection/sepsis may take longer to heal.

Recovery at Home

Drain Management

In case you are discharged with the catheter:

• Maintain the point of drainage clean and dry.
• Do not drag or manipulate the catheter.
• Empty drainage bag (when fitted) daily.
• Change dressing according to instructions.
• Monitor redness, swelling or pain intensity.

Antibiotics

• Oral antibiotics should be used 2-4 weeks or prescribed.
• Take the entire course in order not to repeat.

Activity

• No heavy lifting, bending, or hard work during 1-2 weeks.
• Light exercise is promoted.
• Stay out of the water; bathe by sponge bath until the drain is open again. 

Diet

• Light, simple foods that can be easily digested
• Adequate hydration
• No alcohol until the liver is healed. 
• High protein diet aids in recovery.

Duration of Recovery

Drain Removal

The pigtail catheter is removed in case of:

• Drain output is reduced to a large extent.
• Abscess abacus atrophies on radiographs.

Symptoms improve

• Typically 5-10 days, however, can take 2-3 weeks with large abscesses.

Full Recovery

• The majority of patients heal their bodies in 2-4 weeks.
• In case of large or multiple abscesses: 4- 6 weeks.

Liver abscess percutaneous drainage complications

Percutaneous drainage of a liver abscess is deemed to be generally safe, minimally invasive and very successful (80-95%). Nevertheless, similar to any medical practice, it has certain potential risks. The complications tend to be uncommon and can be treated in most cases at an early stage.

Common but Mild Complications

• Pain or Discomfort at the Drain Site
• Fever

Complications associated with Catheter

• Catheter Blockage
• Catheter Dislodgement (coming out accidentally)
• Leakage Around the Catheter
• Catheter Infection

Complications associated with Procedure (Rare)

• Bleeding
• Injury to neighbouring organs. 

Complications associated with Abscess

• Incomplete Drainage
• Persistent or Recurrent Abscess

Systemic Complications (Uncommon)

• Sepsis
• Leakage of Bile
• Pleural Infection

Late Complications

• Formation of a Fistula (Rare)
• Scar Formation at Drain Site

Liver abscess percutaneous drainage success rate

The success rate of percutaneous drainage is high; it is the treatment of first line applied to most liver abscesses.

Overall Success Rate: 80% – 95%

• This means that 8-9.5 patients out of 10 are successfully treated without surgery. 
• In this era of appropriate antibiotics, it is the best and safest way to drain a liver abscess. 

Factors Affecting Liver abscess percutaneous drainage cost in India

The determinants of the Percutaneous Liver Abscess Drainage cost in India:

Hospital Type & Location

• A full privately owned tertiary hospital within a metro area (Delhi NCR, Mumbai, Bengaluru) will be more expensive. As an example, the factor of hospital or clinic is stated. 
• Small cities and government hospitals can have reduced tariffs.
• Extra expense in case of travel/set up of international patients.

Complexity & Size of Abscess

• Abscess more than 5 cm or multiple abscesses = increased time, increased imaging, perhaps increased drainage catheters or increased hospital stay.
• Abscesses that are multiloculated or inaccessible will raise expense.
• Severity (e.g., related sepsis, underlying liver disease) will increase cost.

Imaging & Guidance Method

• Ultrasound versus CT versus fluoroscopy. CT guidance is costlier.
• Additional costs include pre-procedure imaging (ultrasound, CT, MRI).
• Monitoring and intra-procedure imaging (additional radiology charges, contrast possibly) are also expensive.

Anaesthesia & Procedural Fees

• Either consciously performed under local anaesthesia, sedation or general anaesthesia. It would be more expensive with general anaesthesia. 
• Surgeon/interventional radiologist fee: the more experienced specialists are costlier.

Hospitalization and follow-up treatment

• Big variation in costs is on Bed category (general ward vs private deluxe room).
• Length of stay: problems or delayed recovery=longer stay=more money.
• Aftercare: follow-up, medications, daily changes of dressing, follow-up scans.

Consumables & Medications

• Guide-wire, cost of drainage catheter, disposables, sterile equipment.
• Antibiotic and other medication costs, lab tests, culture and sensitivity.
• In case of complications (bleeding, infection) additional drugs or measures are more expensive.

Other Interventions or Complications

• When the drain requires to be repositioned or a second catheter inserted the cost increases.
• Need for ICU admission, re-imaging or conversion to open surgery/laparoscopic drainage adds tremendously to cost.
• Associated illnesses (diabetes, liver cirrhosis) may add to the cost of monitoring.

Follow-Up & Aftercare

• After you are discharged from the hospital, you may have another imaging test (ultrasound/CT). 
• Drain removal procedure.
• Other outpatient visits, post discharge medications.
• More cost is incurred when patient requires more antibiotic treatment or re-hospitalization.

Conclusion

Percutaneous drainage of liver abscess has been established as a highly effective and least invasive treatment modality, which has emerged to be the choice of treatment option in the first line management of both pyogenic and amoebic liver abscesses. It is a combination of the benefits of fast symptom resolution, low-risk of complications, and short hospitalization than open surgical drainage. The procedure with the use of ultrasound or CT guidance provides the accuracy of reaching the abscess cavity, which enables the effective removal of pus, as well as recovery. Majority of the patients get a lot better in a few days and the success rate is usually high in combination with proper antibiotic treatment.

FAQ

Is just antibiotics enough for liver abscess?

• Small abscesses (less than 3cm in diameter) may be treated with antibiotics alone, but the vast majority require drainage.

Can the abscess come back after drainage?

• Yes, a recurrence may occur in about 10%, most frequently due to residual pus, resistant bacteria or other persisting aetiological factors.

Do I have to stay in the hospital?

• Yes, most patients can be discharged 2-5 days after the procedure, depending on their rate of recovery.

Can I return to normal activity after the surgery? 

• Light exercises can be restarted in a couple of days, although he should not work hard during 2-3 weeks.

Does percutaneous drainage outperform surgery?

• Yes. It is less painful, less dangerous, has a lower hospitalization period, and fewer complications. The surgery is applied in cases where there is no possibility of drainage or complications arise.
