Choledochal Cyst Excision

Choledochal cyst surgery

A choledochal cyst is an unusual (congenital) dilatation of the bile ducts.Excretion of bile from the liver to the foetal intestine through the bile ducts in the liver is disturbed. Without treatment, it can lead to infection, pancreatitis, liver damage, or bile duct cancer.

Why surgery? 

Surgery is positive and mandatory since choledochal cysts:

• Do not resolve on their own
• Bear a high life-time risk of cholangitis and cancer.
• May lead to repeated pain, jaundice, fever or pancreatitis.
• The standard of care is with total removal of the cysts.

Surgical types of choledochal cyst

Total removal of the cyst

• The abnormal bile duct as a whole is excised.
• This is essential in mitigating cancer.

Biliary reconstruction 

• After the cyst has been excised, the bile flow is the only thing that is restored by connecting the ducts of the liver to the small bowel. 
• This is the most widely done reconstruction.

Surgical approaches

Open surgery

• Traditional method
• Larger incision
• Applied in more complicated or difficult cases.

Laparoscopic surgery

• Minor cuts, shorten pain, quick healing.
• Very popular in established centers.

Robotic surgery

• High-technology least invasive alternative.
• Greater accuracy in chosen centers.

Pediatric choledochal cyst excision

It is a one- stage operation with a curative intent for the child having a dilated, abnormal BD (choledochal cyst) which is completely excised and the bile is directed into the gut. 

Once diagnosed, surgery is required regardless of whether the child has mild or no symptoms.

The reason why surgery is necessary for children

In the absence of surgery, a choledochal cyst may result in:

• Recurrent jaundice
• Abdominal pains and fever (cholangitis)
• Pancreatitis
• Progressive liver damage
• Higher chances of contracting bile duct cancer in the future.
• These complications are avoided by early excision during childhood.

Ideal age for surgery

• Typically done shortly after diagnosis.
• Usually at 3-12 months of age when it is detected during infancy.
• Children that are old are activated as soon as they are medically fit.

Laparoscopic choledochal cyst excision

It is peeling surgery that the diseased bile duct(choldochal cyst) is entirely resected through the one or more small keyhole incisions with biliary reconstruction, usually in the form of Roux-en-Y hepaticojejunostomy to reestablish bile flow. 

This practice has become very acceptable as the mode of choice in mature centers particularly among the children.

Who is suitable?

Laparoscopic excision should be used in:

• The vast majority of Type I and Type IV choledochal cysts.
• Children, adolescents, and selected adults.
• There are uninfected or mildly liver-damaged patients.

Procedure:

Port placement

• 3–5 small incisions (5–10 mm)
• Fine instruments and camera put in.

Dissection and excision of cysts

• Total excision of the engorged extrahepatic bile duct.
• Simultaneously removed gallbladder.
• Portal vein and hepatic artery should be carefully preserved.

Biliary reconstruction

• A part of a small intestine is raised.
• Connected to the liver bile duct to drain the bile.
• Drain placement and closure
• Temporary drain placed
• Minor cuts suturelessly.

Duration of surgery

4–6 hours, depending on:

• Age and size of patient
• Type of cyst
• Degree of inflammation

Hospital stay

• 5-8 days (not as long as open surgery)

Choledochal cyst excision procedure

Choledochal cyst removal is an absolute surgical cure whereby the abnormal and enlarged bile duct is totally removed, and replaced with a reconstructive surgery to enable bile to flow normally out of the liver into the intestine.

The gold standard is complete excision + biliary reconstruction.

Preparation before Surgery

The team will normally pre-operative:

• Blood tests (LFTs, coagulation profile)
• Ultrasound / MRCP
• Ms. Treat any acute infection (cholangitis).
• Antibiotics and preoperative starvation.

Procedure

Step 1: Anaesthesia

• General anaesthesia
• Patient is in a complete sleep and pain-free.

Step 2: Surgical access

• Laparoscopic (3-5 small incisions) method.

or

• Single abdominal incision (open approach).
• Choice is based on age, type of cyst and experience of the surgeon.

Step 3: Exposure of bile duct

• Liver gently retracted
• Bile duct cysts and structures detected.

Careful protection of:

• Portal vein
• Hepatic artery
• Pancreatic duct

Step 4: Complete cyst excision

• Complete extrahepatic cyst of bile duct is excised.
• Removal of gallbladder is performed at the same time (cholecystectomy).
• Lower end oriented proximity to the pancreas.
• Torn at the healthy hepatic duct, upper end.
• Total elimination is vital to avoid cancer and recurrence.

Steps 5: Biliary reconstruction

• A small intestinal loop is obtained.
• One end is connected to liver biliary duct.
• Smoothes out the blocked bile into intestine.

Step 6: Drain placement and closure.

• Temporary abdominal drain done.
• Incisions closed

Duration of surgery

• 4–6 hours on average
• Longer in complex cases

After surgery (recovery)

Hospital stay

• 7–10 days
• IV fluids slow down to oral feeding.

First few weeks

• Mild abdominal discomfort
• Avoid strenuous activity

Full recovery

• 4–8 weeks

Choledochal cyst excision recovery

It is hereby an easy phase-by-phase recovery after the choledochal cyst excision, laparoscopic or open surgery.

Immediate recovery (Day 0–3)

What to expect

• Surveillance of ICU/HD ward (usually 24-48 hours) in pediatrics.
• IV fluids and antibiotics with analgesia. 
• Temporary Abdominal drain present.
• No oral feeds initially

Care focus

• Vital signs and urine output
• Liver function tests
• Motion in early stages to avoid rigidity.

Early hospital recovery (Day 4–10)

Progress

• Slow introduction of oral feeds (liquids being the first and soft diet being the second)
• Drain is removed when the output of bile is negligible.
• Suffering reduces to a great extent.
• Child/adult starts to walk pleasurably.

Discharge

• Usually 5–8 days (laparoscopic)
• 7–10 days (open surgery)

Home recovery (Weeks 2–4)

What’s normal

• Mild tiredness
• Periodic stomach-ache.
• Healing surgical wounds

Do’s

• Light activity and walking
• Regular meals
• Wound care as advised
• Complete antibiotic course

Don’ts

• Heavy lifting
• Strenuous exercise
• Swimming until wounds heal

Full recovery (Weeks 4–8)

• Return to school/work
• Normal physical activity
• No nutritional limitations unless recommended.
• Scars continue to fade

Pain management

• 5-10 days oral pain medicine.
• Laparoscopic surgery is normally less painful.

Post-excision diet in case of choledochal cysts

• Begin with food that is easy to digest.
• Progressively take up normal diet.
• No permanent nutritional prohibitions.
• Encourage hydration

Follow-up schedule

• First visit: 7-10 days after discharge.
• Periodical liver functions test.
• MRCP or ultrasound as recommended.
• Recommended long term annual follow up.

Conclusion

Choledochal cyst resection is a conclusive therapy that is life-saving and has excellent long-term results when the cyst is fully excised and bile drainage restored appropriately. In the current procedures, particularly laparoscopic surgery, the majority of patients have a smooth recovery, fewer complications, and back to normal lives in a few weeks. The main outcomes of serious complications prevention are the early diagnosis, timely surgery, and regular long-term follow-up. The prognosis is massively positive and both children and adults can lead healthy and free life after recovery.

FAQ

1. Is it necessary to remove choledochal cyst?

• Yes. Surgery is the definitive treatment. Not treating the cyst poses dangers of infection, liver damage, pancreatitis and cancer of the bile ducts.

2. What is the best operation for choledochal cyst?

• Total cyst excision with Roux- en -Y hepaticojejunostomy is the gold standard. It may be performed laparoscopically or as an open procedure.

3. Is laparoscopic surgery safe for children and infants?

• Yes. Laparoscopic excision is safe and the preferred treatment in high pediatric centers for infants as well.

4. Will my choledochal cyst be back after surgery?

• No, if cyst is completely excised. Partial resection leads to higher risk of late complications.

5. Will I have long-term problems with digestion or diet?

• No. You eat normally, and you do not need a special diet.

6. Is there still a risk of getting cancer after surgery?

• The risk is greatly reduced after full excision, but life-long follow-up is recommended.
