Radiological treatment of common bile duct lithiasis in infancy

Single Procedure Saline Lavage for Treatment of Inspissated Bile

Inspissated bile syndrome is a rare cause of cholestatic jaundice in infancy, occurring due to obstruction of the biliary ducts and gallbladder by biliary sludge. Traditional methods of treatment include surgical drainage or cholecystostomy drain placement. Both can be associated with complications and prolonged admission. We present 2 cases treated with a single percutaneous needle puncture of the gallbladder followed by saline lavage. Two neonates presented with cholestatic jaundice and sonographic evidence of biliary sludge and dilation of the common bile duct. Single sonographic-guided needle puncture of the gallbladder was followed by irrigation with saline. Clearing of the biliary sludge was confirmed by sonography and cholecystocholangiography. There was resolution of the cholestatic jaundice, with no complications or repeat procedures.

Inspissated bile syndrome; Safe and effective minimally invasive treatment with percutaneous cholecystostomy in neonates and infants

PURPOSE

Inspissated bile syndrome (IBS) is a rare cause of obstructive jaundice in neonates and infants with several treatment options reported. We present our experience with the use of minimally invasive ultrasound-guided percutaneous cholecystostomy drain catheter placement with ongoing saline lavage in neonates and infants.

METHODS

Retrospective chart review of patients treated with percutaneous cholecystostomy, from February 2010 till June 2015. We reviewed the technical and clinical success along with complications of the procedure.

RESULTS

There were 6 patients, mean age 17weeks (range 4-40). Most had significant risk factors for IBS presenting with biliary obstruction. A total of 7 procedures performed on the 6 patients, with a technical success rate of 6/7. One patient required cannulation of the intrahepatic biliary system. Drains were flushed for a median of 26days (10-70). Clinical success was achieved in all patients. 3 had displacement of the drain, one of which required re-insertion. Another developed a small sub-hepatic collection post procedure with pyrexia. On long term follow up one was found to have a forme fruste choledochal cyst.

CONCLUSION

Centers with suitable interventional radiology services ultrasound-guided percutaneous cholecystostomy drain catheter placement with ongoing saline lavage is a safe and effective minimally invasive treatment for IBS in neonates and infants.

Common bile duct stones in infancy: a medical approach

Symptomatic choledocholithiasis in infancy is not common. It usually presents with jaundice and acholic stools and is diagnosed on abdominal ultrasonography. Favourable outcome of conservative management has been reported, but specific management guidelines are not well defined in the literature. We describe three cases using a combination of ursodeoxycholic acid and antibiotics as a treatment paradigm, which could potentially negate more invasive treatment. All three patients had ultrasonography proven choledocholithiasis with concomitant obstructive liver function test. They were treated with a combination of ursodeoxycolic acid and antibiotics. Patient 1 had an Escherichia coli urinary tract infection and was treated with oral bactrim. Intravenous amoxicillin, gentamicin and metronidazole were used for the other two patients. All three patients responded with a return to normal-coloured stools within 48 h of combination treatment. Repeat ultrasonography done within 11 days after the first study for all three patients confirmed complete resolution of choledocholithiasis. It is postulated that this improvement is as a result of a reduction in inflammation and oedema, associated with a low-grade cholangitis, following antibiotic treatment. This is coupled with improved bile flow with ursodeoxycholic acid therapy. The findings suggest the potential application of this safe, non-invasive therapeutic strategy as initial management in infants with this condition. A follow-up prospective randomised controlled trial may be an answer to prove the validity of this observation but due to the rarity of this problem, it would be a challenge to recruit sufficient number of patients.

Balloon sphincteroplasty in the management of choledocholithiasis in a 10-week-old infant

The management of common bile duct stones in neonates has not been clearly fully standardized, although percutaneous image-guided washing of the bile duct is generally adopted as the first-line treatment. We report the case of a 10-week-old infant with a choledocholithiasis in whom anterograde sphincter balloon dilation was achieved by combining image-guided access and flexible gastroduodenoscopy. This mini-invasive strategy may be an alternative to surgery in cases of impacted choledocholithiasis resistant to bile duct washing.

Gallstone pancreatitis in children: atypical presentation and review

Pancreatitis in children is less common than in adults and is mostly related to trauma, infection and anatomical anomalies. Gallstone pancreatitis is an even rarer entity in infants and children. We present an unusual case of gallstone pancreatitis in a 17- month-old girl who presented with jaundice of 1 month duration. The laboratory studies showed conjugated hyperbilirubinaemia with associated acute pancreatitis and pseudo-hyponatraemia secondary to the markedly elevated lipid profile. Further evaluations revealed obstruction at the Ampulla of Vater with no evidence of a choledochal cyst and no mass lesion seen in the pancreas. The patient initially underwent urgent decompressive cholecystostomy with intraoperative cholecystography. When the biochemical parameters improved, the patient underwent formal cholecystectomy with common bile duct exploration, extraction of multiple impacted stones in the ampullary region and Fogarty balloon sphincterotomy. The post-operative course was uneventful.

CONCLUSION

Acute gallstone pancreatitis in children may present as jaundice or abdominal pain. Recognition, early diagnosis and surgical intervention are the mainstay for a good outcome.

Successful nonoperative management of neonatal acute calculous cholecystitis

Acute cholecystitis in the neonate is rare and usually treated by cholecystectomy. A 1-day-old full-term girl had clinical and sonographic features of acute calculous cholecystitis. This was successfully managed nonoperatively with intravenous fluids and antibiotics, leading to complete resolution of the condition. The infant currently is thriving and asymptomatic with a sonographically normal biliary tree. Spontaneous resolution of cholelithiasis may occur in neonates, even in the presence of acute cholecystitis.

Ultrasonographic diagnosis of fetal cholelithiasis

A case of opacity in the fetal gallbladder was diagnosed by ultrasound. The lesion resolved spontaneously in the postnatal period. Careful follow-up ultrasound examinations are necessary for fetal cholelithiasis in the pre- and postnatal periods, and conservative management is mandatory.

Choledocholithiasis in a premature neonate

Choledocholithiasis in neonates and infants has been reported only rarely. Infants with complications of prematurity are more predisposed to development of biliary calculi. With the current widespread use of diagnostic ultrasonography, more neonates may be found to have gallstones and common bile duct stones. We describe a case of choledocholithiasis and cholelithiasis in a premature neonate successfully treated by surgical placement of a cholecystotomy tube and irrigation of the biliary system.

[Cholelithiasis in infants with spontaneously favourable course]

BACKGROUND

Nonoperative interventional treatment of cholelithiasis has been performed in young infants suffering from jaundice.

CASE REPORT

A neonate was admitted because he suffered from severe anemia and jaundice due to Rh incompatibility. He developed cholestasis when he was 7 weeks-old; ultrasonography showed nonshadowing echogenic material in the gallbladder suggesting biliary sludge. A second ultrasonography performed 24 hours later showed a normal gallbladder while sludge had migrated into the lower part of the common bile duct. This biliary sludge spontaneously resolved in a few days.

CONCLUSIONS

Biliary sludge, even symptomatic in infants, may resolve without surgery or nonoperative interventional treatment. Ultrasonography is useful in following migration.

Cholelithiasis in infancy: a study of 40 cases

During a 17-year period, 40 infants less than 1 year of age were investigated for cholelithiasis; 32 infants were seen within the past 10 years. Seventeen of them had no recognizable predisposing factors. In 6 infants, gallbladder lithiasis was a fortuitous finding on a plain radiograph or sonogram with no signs of common bile duct obstruction; under conservative management, no complications of lithiasis were observed on follow-up of 3 infants and spontaneous resolution occurred in 2 others. In the remaining 34 infants with lithiasis of the common duct or cystic duct or both, the initial symptoms were cholestatic jaundice in 21, acholic stools in 8, sepsis in 4, and abdominal pain in 1. Ultrasonography, performed in 33 of them, showed dilation of the biliary tract in 28, and stones in the gallbladder in 13 and in the bile ducts in 10. Percutaneous transhepatic cholangiography or operative cholangiography in 26 infants showed stones in the bile ducts in 23. In 3 infants, no lithiasis was visible, suggesting the spontaneous elimination of stones. Treatment was initially surgical in 9 infants, but starting in 1981 interventional radiologic procedures were attempted in 15 infants and were successful in 12. Spontaneous resolution of cholelithiasis occurred in 10 other infants with cholestasis. Recurrence of biliary stones was observed in 3 infants only after a follow-up of 7 months to 10 years. These results suggest that common bile duct lithiasis should be considered among the causes of cholestatic jaundice in infancy, and that some of the gallbladder calculi found in older children may have resulted from a lithogenic process that occurred during fetal life or shortly after birth. Percutaneous cholangiography with biliary drainage appears to be an effective means of treatment of infants with common bile duct obstruction; surgery can then be restricted to a limited number of cases, especially those with associated strictures of the bile ducts.

Cholelithiasis in newborns and infants

Cholelithiasis in infants is rare, and has usually been associated with hemolysis, ileal disease, congenital anomalies of the biliary tree, hyperalimentation, and prolonged fasting. With the increased use of abdominal ultrasonography (US), more cases of cholelithiasis are being discovered. We report our experience with 13 infants diagnosed on abdominal US to have gallstones. There were 9 boys and 4 girls with an average age at diagnosis of 2.6 months (range, 0 to 9 months). Predisposing factors could be identified in only 6 of the 13 patients. Two patients with obstructive jaundice underwent cholecystectomy and common bile duct exploration. One patient with choledocolithiasis and common bile duct dilatation was observed. His stone passed spontaneously, with resolution of symptoms. Ten patients without cholestasis remained asymptomatic, with disappearance of lithiasis in five of them. Neonatal cholelithiasis is more common than previously suspected; it seems to affect males more often than females and is usually not associated with known predisposing factors. It appears to be a temporary, self-limiting phenomenon, and an aggressive approach is not warranted in the asymptomatic infant. Surgical or radiological intervention should be reserved for the symptomatic patients or those with underlying lithogenic disorders.

Therapeutic and diagnostic implications of acquired choledochal obstruction in infancy: spontaneous resolution in three infants

Three infants aged 2 days to 11 weeks with conjugated hyperbilirubinenemia, had sonographically documented dilated common hepatic bile ducts, and echogenic material in the gallbladder. A 2-day-old infant, born to a diabetic mother, had none of the classic predisposing factors for cholelithiasis, and two infants had received total parenteral nutrition (TPN) and TPN plus furosemide. The first infant after receiving 4 1/2 weeks of TPN and furosemide, developed common duct obstruction with increasing bilirubin and hepatic duct caliber over a 12-day period. An operation was scheduled; however, on the following day the bilirubin dropped abruptly and surgery was canceled. The experience with this infant encouraged conservative management in two subsequent infants with similar clinical and sonographic findings. Spontaneous resolution occurred 9 days after the onset of common duct obstruction in one infant and after 16 days in the other.
