Summary
Magnetic compression anastomosis (MCA) successfully treated a biliary atresia complication. This less invasive technique reopened an obstructed cyst-jejunostomy, resolving jaundice in a young patient.
Area of Science:
- Hepatobiliary surgery
- Pediatric surgery
- Gastroenterology
Background:
- Biliary atresia (BA) is a serious neonatal liver condition requiring surgical intervention.
- Anastomotic obstruction is a potential complication following BA surgery, leading to jaundice.
- Percutaneous trans-hepatic cholangiodrainage (PTCD) can temporarily manage obstructive jaundice.
Observation:
- A 16-year-old female with a history of BA surgery presented with obstructive jaundice.
- Contrast injected via PTCD showed no flow through the cyst-jejunostomy anastomosis.
- Magnetic compression anastomosis (MCA) was employed to address the anastomotic obstruction.
Findings:
- MCA involved placing magnets in the cyst and jejunum to compress the partition.
- Anastomotic recanalization was achieved by postoperative day 6.
- A trans-anastomotic PTCD tube was maintained for 245 days, ensuring sustained bile flow.
- The patient remained jaundice-free after PTCD removal.
Implications:
- MCA offers a less invasive approach for managing biliary tract anastomotic obstruction in BA patients.
- Successful MCA can prevent the need for more complex reconstructive surgeries.
- This case highlights MCA as a viable treatment option for late-onset anastomotic complications post-BA repair.
