Radiol Case Rep 2023; 18:4134-4136. [PMID: 37745755 PMCID: PMC10511725 DOI: 10.1016/j.radcr.2023.08.083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Accepted: 08/18/2023] [Indexed: 09/26/2023] Open
Abstract
Infantile cholelithiasis is a rare occurrence. It is often diagnosed incidentally during ultrasonography for other conditions as most cases are asymptomatic and may be self-limiting. A few cases may however present with prolonged neonatal or infantile jaundice. We report our initial experience with an incidental case of infantile cholelithiasis in an 8-week-old male infant who was brought to our ultrasound unit in Accra, Ghana, for an abdominal ultrasound on account of conjugated hyperbilirubinemia and pigmented stools. The patient had presented initially at the children's emergency unit of the Korle-Bu Teaching Hospital, 2 days after an uneventful delivery, with a history of yellowing of the eyes, noticed on the first day of life, which necessitated the request for the ultrasound examination, leading to this rare finding of infantile cholelithiasis. The availability and use of modern sonographic equipment are likely to result in more effective detection of this incidental finding and its subsequent management.

Abstract
INTRODUCTION The incidence of fetal gallstones is estimated at 0.45% and its clinical relevance after birth remains unknown. This study aimed to describe the natural history of fetal gallstones and their clinical sequelae after birth. METHODS We queried a database of fetuses referred for second and third trimester sonograms performed for high-risk pregnancies, and identified cases with fetal gallstones (1996-2019). Demographics, prenatal/postnatal imaging findings, and clinical sequelae were collected. A literature review was performed according to PRISMA guidelines. RESULTS We screened approximately 200,000 obstetric sonograms; 34 fetuses were found to have cholelithiasis. The median gestational age at the time of sonogram was 35 weeks (range 22-38). Fifty-six percent were female and 11.8% were twin pregnancies with one affected fetus. Median maternal age was 28 years (range 17-42). Eight fetuses underwent postnatal imaging and 4 had persistent cholelithiasis. There was one case of in utero demise. Two patients had structural anomalies (renal and cardiac) by sonogram. A subset of 17 patients was followed long-term (range 3-20 years), and none developed clinical sequelae from cholelithiasis. DISCUSSION/CONCLUSIONS No child developed postnatal clinical sequelae related to cholelithiasis identified in utero. Fetal cholelithiasis can be managed expectantly without follow-up imaging in asymptomatic patients.

Abstract
Background Jaundice within the first 1–2 weeks of a neonate’s life will generally self-resolve; however, if it lasts longer than this time frame it warrants further work up. Direct or conjugated hyperbilirubinemia can suggest neonatal cholestasis, which in turn reflects marked reduction in bile secretion and flow. The differential diagnosis for neonatal cholestasis is broad. Neonatal choledocholithiasis is a rare cause of neonatal cholestasis, but should be considered on the differential diagnosis for patients presenting with elevated conjugated bilirubin. Case presentation We describe an infant who presented with neonatal cholestasis. He subsequently underwent work up for biliary atresia, as this is one of the more time-sensitive diagnoses that must be made in neonates with conjugated hyperbilirubinemia. He was ultimately found to have choledocholithiasis on magnetic resonance cholangiopancreatography. He was managed conservatively with optimizing nutrition and ursodeoxycholic acid therapy. Conclusions We found that conservative management, specifically optimizing nutrition and treating with ursodeoxycholic acid, can be a sufficient approach to facilitating resolution of the choledocholithiasis and conjugated hyperbilirubinemia.

Abstract
PURPOSE To investigate the prevalence of echogenicity in the fetal gallbladder (EFG) and to present prenatal sonographic findings and their postnatal outcomes. MATERIALS AND METHODS We performed a retrospective study within 17420 pregnant women during a 66-month period. Fetuses with an incidental finding of EFG in their 2nd or 3rd trimester of pregnancy were followed until birth per two weeks with sonographic examinations. RESULTS Out of 5977 fetuses, 44 fetuses were found to have EFG with a prevalence of 0.74%. Nine (20%) of 44 fetuses had single echogenicity, 25 (56%) had multiple echogenicities, 10 (22%) had sludge-like echogenicities. In Doppler sonography, 28 fetuses with EFG exhibited twinkling artifacts; however, none of the echogenicities had obvious acoustic shadowing. All of the cases were resolved either in utero or after birth before 10 months of age. CONCLUSION EFG is a late third-trimester phenomenon with a prevalence of 0.74%. Most EFGs presented as twinkling artifacts, suggesting they had a cholesterol component.

Abstract
Aims and Objectives: The incidence of cholelithiasis is now increasing in children. Besides hemolytic diseases, there are also nonhemolytic conditions and idiopathic group. A large number of children belong to asymptomatic group who do not present with gallstone-related symptoms. There is no consensus in the management of these children. The aim of this study is to evaluate the role of elective cholecystectomy in asymptomatic cases to prevent complications which leads to more morbidity. Materials and Methods: One hundred and seventy-eight children were treated over a period of 12 years and they were divided into two groups according to their age at presentation. Sixty-four children below 5 years belonged to Group A and 114 children between 5 and 12 years belonged to Group B. About 71.8% of children of Group A and 49.1% of children of Group B were asymptomatic. Cholecystectomy was advised in all cases of Group B and all symptomatic cases of Group A. In Group A asymptomatic cases, ursodeoxycholic acid (UDCA) was given for 6–12 months and followed up. Results: Laparoscopic cholecystectomy was performed in all cases except in five cases where conversion to open surgery was done as there was gross adhesions due to previous laparotomy. Of 46 asymptomatic cases of Group A, the stone disappeared in seven cases, 12 children developed symptoms, and there was no change in 27 patients. Stone reappeared again in three of seven children who were managed by cholecystectomy. Cholecystectomy was also performed in 12 cases that developed symptoms. In the rest of the 27 children, cholecystectomy was advised after 1 year trial of UDCA. Cholecystectomy was advised in both symptomatic and asymptomatic cases of Group B. Sixteen of 56 asymptomatic cases did not agree for cholecystectomy and 12 of them returned with complications. Endoscopic retrograde cholangio-pancreaticography (ERCP) and stone extraction was performed in four cases. In all the acute cases, cholecystectomy was performed after a period of conservative management. Conclusion: UDCA can be tried in the smaller age group below 5 years, but there is a chance of recurrent stone formation. Elective laparoscopic cholecystectomy should be the choice in all asymptomatic cases to prevent complications.

Abstract
BACKGROUND Gallstones are uncommon in infants and children and Asian children are thought to have very low risk. Diagnoses have increased in recent years with the widespread use of ultrasonography (USG). This study aimed to review our experience with risk factors, complications, and treatment of pediatric gallstones in low-incidence populations. METHODS We retrospectively reviewed patients younger than 18 years old diagnosed with gallstones using USG between November 2006 and December 2012 in a tertiary referral hospital in Taiwan. Demographic information including age and sex, follow-up period, USG findings, predisposing factors, complications, treatment approaches and outcomes were recorded. RESULTS Ninety-eight children with gallstones diagnosed with USG were enrolled and reviewed in our study. Females comprised 55% of patients, with no specific gender tendency. No risk factor could be identified in 30.8% of patients. The most common risk factors were cephalosporin (CS) use, presence of a choledochal cyst (CC), and spherocytosis. CS use was not associated with a higher dissolution rate. The presence of type IVa CC implied a high rate of gallstone recurrence after Roux-en-Y hepaticojejunostomy. Complications were seen in 22.4% of patients, but only two needed emergency stone removal. Expectant management was performed in 61% of patients and 62.5% of them achieved spontaneous resolution; the stone dissolution rate was not lower than in the group treated with ursodeoxycholic acid (UDCA). Stone size was significantly decreased after UDCA use if resolution did not occur. CONCLUSIONS Pediatric gallstones showed high resolution rate, and the clinical course was largely benign. CS use was the most common risk factor and did not predict a higher dissolution rate. Type IVa CC was also an important risk factor associated with a high recurrence rate. Conservative treatment and oral UDCA may be reasonable strategies in most patients, unless complications are present.

Abstract
BACKGROUND/PURPOSE The incidence of choledocholithiasis is increasing. The diagnosis of common bile duct (CBD) obstruction is based on abnormal CBD size. Establishing norms for CBD size in children would improve diagnostic accuracy. We analyzed ultrasounds (US) to determine normal pediatric CBD size based on age and then validated this against patients with choledocholithiasis. METHODS A retrospective review was conducted for children less than 21 years of age with US defined CBD size. Patients were stratified into age groups by ANOVA statistical analysis. Secondary analysis included patients with confirmed choledocholithiasis in comparison to the normal cohort. RESULTS A total of 778 patients had US without pathology. Group 1 (<1 year) had a mean CBD of 1.24±0.54 mm, group 2 (1-10 years) 1.97±0.71 mm, and group 3 (>10 years) 2.98±1.17 mm, p<0.05. Fourteen additional patients were found to have choledocholithiasis with a mean CBD size of 8.1 mm. All patients with choledocholithiasis had CBD sizes outside of our normal range, but only 50% of patients had enlarged CBD size based on adult normal range of values. CONCLUSION Normal CBD size in children is less than a normal adult patient. More accurate normal values will aid in determining if a child needs further evaluation for possible obstruction of the CBD. TYPE OF STUDY diagnostic Level of evidence: III.

Abstract
PURPOSE Infantile cholelithiasis is a rare disease process, and management strategies are poorly defined. We therefore examined the risk factors, complications, and management of this disease at our institution. METHODS We retrospectively reviewed infants with cholelithiasis diagnosed on ultrasound between 1997 and 2013. Details of the patient's medical history, presentation, imaging findings, laboratory values, and treatment were reviewed and analyzed. RESULTS Over the 16-year period, 50 infants were evaluated for cholelithiasis. Thirty-seven (74%) had at least one risk factor for gallstone development which included total parenteral nutrition, diuretic therapy, cephalosporin antibiotic treatment, sepsis, congenital heart disease (CHD), prematurity, or a malabsorptive gastrointestinal condition. Thirteen (26%) infants were symptomatic, most commonly presenting with emesis and jaundice. Complications from gallstones included choledocholithiasis (9), cholecystitis (3), and pancreatitis (1). Nearly half (6/13) of patients with complicated cholelithiasis had CHD. Of infants presenting with complications, 9 had a cholecystectomy, most commonly via a laparoscopic approach, 2 had an ERCP for choledocholithiasis, and 2 were medically managed. In patients managed conservatively, resolution of gallstones occurred in 25%. CONCLUSIONS Infantile cholelithiasis has variable outcomes ranging from spontaneous resolution to choledocholithiasis or cholecystitis. While patients with complicated cholelithiasis often undergo an operation, infants <1year of age have higher anesthetic and surgical risks. Conservative management with ERCP or medical treatment can also be successful, which offers an alternative to operative intervention in properly selected patients.

Abstract
Congenital biliary tract anomalies typically present with neonatal cholestasis. In children and adults, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are used to evaluate and treat choledochal cysts. Contrarily, endoscopy has traditionally played a minor role in the diagnosis of the cholestatic infant. Recent studies support the incorporation of ERCP into the diagnostic algorithm for biliary atresia and neonatal cholestasis. But at present, most pediatric liver centers do not consider its use essential. This article reviews the congenital biliary tract anomalies in which endoscopy has been shown to contribute to the evaluation of the cholestatic infant.

Abstract
Gallstone disease in children is evolving, and for the previous 3 decades, the frequency for surgery has increased greatly. This is in part because of improved diagnostic modalities, but also changing pathology, an increased awareness of emerging comorbidities, such as childhood obesity, and other associated risk factors. This article outlines the pathophysiology, genetics, and predisposing factors for developing gallstones and includes a review of the literature on the current and more novel medical and surgical techniques to treat this interesting disease.

Abstract
CONTEXT little is known about the epidemiology of cholelithiasis in children. Cholelithiasis and choledocholithiasis were considered to be uncommon in infants and children but have been increasingly diagnosed in recent years due to wide- spread use of ultrasonography. However, there is not much of information from India and no consensus among Indian pediatricians and pediatric surgeons regarding management of gallstones in children. Hence, the purpose of this review is to increase awareness about the management of gallstones in children. METHODS extensive electronic (PubMed) literature search was made for this purpose and literature (original articles, clinical trials, case series, review articles) related to gallstones in children were reviewed. CONCLUSIONS the etiologies of cholelithiasis are hemolytic (20% -30%), other known etiology (40%-50%) such as total parenteral nutrition, ileal disease, congenital biliary diseases, and idiopathic (30-40 %). Spontaneous resolution of gallstones is frequent in infants and hence a period of observation is recommended even for choledocholithiasis. Children with gallstones can present with typical biliary symptoms (50%), nonspecific symptoms (25%), be asymptomatic (20%) or complicated (5% -10%). Cholecystectomy is useful in children with typical biliary symptoms but is not recommended in those with non-specific symptoms. Prophylactic cholecystectomy is recommended in children with hemolytic disorders.

Abstract
BACKGROUND AND OBJECTIVE The increasing use of sonography has resulted in an increase in the proportion of children with gallstones who are asymptomatic at the time of diagnosis. In adults, the literature supports expectant management of clinically silent gallstones. The evidence for this management approach in children is limited to a number of small series. Our objective was to review the risk factors, complications, and outcomes of gallstones at our institution, particularly in those patients who are asymptomatic at the time of initial diagnosis. MATERIALS AND METHODS We reviewed 382 cases of gallstones in children. These patients were diagnosed with sonography. Data on age at diagnosis, presentation, sonographic findings, risk factors, complications, surgery, and follow-up were collected. A chi2 test was used to compare the complication rates between symptomatic and asymptomatic groups. Descriptive statistics were used to analyze the sample. RESULTS At diagnosis, 50.5% of children were asymptomatic; these patients were diagnosed at a mean age of 8.23 years. Compared with symptomatic patients, they were less likely to have a hemolytic anemia but more likely to have other risk factors, including cardiac surgery, leukemia and lymphoma, short bowel syndrome, or exposure to total parenteral nutrition or cephalosporins. These patients had a lower rate of complications than the symptomatic patients (4.6% vs 28.2% of symptomatic, P < 0.0001) and only 3.1% developed symptoms that necessitated surgery (vs 59.0% of symptomatic). Of the 58 (15.1%) diagnosed in infancy, 47 (81.0%) were asymptomatic. The infant group also had low rates of complications (8.6%) and cholecystectomy (1.7%). In cases with sonographic follow-up, resolution of gallstones was demonstrated in 16.5% of asymptomatic patients and in 34.1% of infants. CONCLUSIONS The data suggest that clinically silent gallstones in children and infants are associated with low rates of complications and can be managed conservatively, unless complications occur. Patients with sickle cell disease, spherocytosis, and elliptocytosis had high complication rates and required surgery more often.

BACKGROUND Laparoscopic cholecystectomy is the treatment of choice in symptomatic paediatric cholelithiasis. However, controversy exists about its role in asymptomatic cholelithiasis and biliary dyskinesia. We have reviewed the experiences of two UK paediatric centres with laparoscopic cholecystectomy over an 8.5 year period and critically evaluated the indications and outcomes of surgery. METHODS Patients who underwent laparoscopic cholecystectomy by a single surgeon at the Royal Aberdeen and Royal Alexandra Hospitals between May 1996 to August 2003 and September 2003 to December 2005, respectively, were studied. Information was extracted from prospectively held databases and analysed. RESULTS A total of 27 cholecystectomies were performed during the period of study. The mean age of patients was 11.7 years with a female preponderance. Symptomatic idiopathic cholelithiasis was the main indication for surgery (14). Cholecystectomy was also performed for haemolytic disease (3), acute recurrent pancreatitis of unknown cause (2), gallbladder trauma (1), and for asymptomatic calcific non-resolving stones (7). All patients were investigated with ultrasound scans with four patients undergoing magnetic resonance cholangiopancreatography (MRCP) for suspected common bile duct (CBD) stones. A standard four-port approach was used with the gallbladder extracted through the umbilical port. The mean operative time in the latter 13 cases was 105 minutes with a median postoperative stay of one day for the whole series. Histology revealed chronic cholecystitis in all but three cases. All patients were discharged after a six-month follow-up period. CONCLUSIONS The advent of laparoscopy has resulted in an expansion of the traditional indications for cholecystectomy. MRCP is a useful investigation in selected children to exclude choledocholithiasis and avoid intraoperative cholangiography. There appears to be no clear correlation between histology and presenting symptoms. The natural history of asymptomatic gallstones in children is not known although a consensus is emerging to support cholecystectomy for all calcific non-resolving gallstones.

[PMID: 18317602 PMCID: PMC11020560 DOI: 10.1590/s1516-31802007000600005] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2006] [Revised: 11/07/2007] [Accepted: 11/14/2007] [Indexed: 11/22/2022] Open
Abstract
CONTEXT AND OBJECTIVE Although studies have demonstrated increased frequency of gallbladder abnormalities among Downs syndrome (DS) patients in some countries, there is only one paper on this subject in the Brazilian literature. The aim of this study was to demonstrate the prevalence, clinical characteristics and evolution of lithiasis and biliary sludge among DS patients in a maternity and childrens hospital in Rio de Janeiro. DESIGN AND SETTING This was a cross-sectional study followed by a retrospective cohort study on all individuals with an ultrasound diagnosis of gallbladder abnormalities. METHODS 547 DS patients (53.2% male, 46.8% female) attending the Instituto Fernandes Figueira in 2001 underwent abdominal ultrasound examination at ages of between one day and three years (mean: five months). Clinical and ultrasound data were analyzed. RESULTS In 50 patients (9.1%), the ultrasound demonstrated gallbladder abnormalities (6.9% lithiasis and 2.1% biliary sludge). Spontaneous resolution was observed in 66.7% of the patients with biliary sludge and 28.9% with lithiasis. Cholecystectomy was carried out on 26.3% of the patients with gallstones. CONCLUSION The results from this study and comparison with the literature suggest that DS patients are at risk of developing lithiasis and biliary sludge and should be monitored throughout the neonatal period, even if there are no known risk factors for gallstone formation. Most frequently, these gallbladder abnormalities occur without symptoms and spontaneously resolve in most non-symptomatic patients. DS patients should be monitored with serial abdominal ultrasound, and cholecystectomy is indicated for symptomatic cases or when cholecystitis is present.

Abstract
OBJECTIVE Evaluation and follow-up of infants with cholelithiasis and pseudolithiasis in a pediatric ward. PATIENTS & METHODS Prospective study from April 1990 to October 2003 identified hospitalized infants younger than 2 years with ultrasonographic findings of cholelithiasis, choledocholithiasis or pseudolithiasis. Associated abnormalities or contributory factors were recorded and patients were followed for from 6 months to 13 years (mean, 4 years). RESULTS Thirty-four patients were diagnosed between the age of 3 weeks and 24 months. Thirteen (38%) had been treated with third-generation cephalosporins. Other associated factors were dehydration in 10 (29%), urinary tract infection in two (6%) and one each for cholestatic liver disease, total parenteral nutrition, immunoglobulin A deficiency and prematurity. Six infants (17%) had no known risk factor. Six additional patients were diagnosed by antenatal ultrasound. CONCLUSIONS Cholelithiasis in infants hospitalized for a variety of common pediatric conditions is not rare. Dehydration and treatment with third-generation cephalosporins are important associated factors. The classic risk factors of hemolysis and previous gastrointestinal surgery, were not found in our group. The overall prognosis was good. Pseudolithiasis disappeared in all infants. Of the 21 infants with cholelithiasis, only two developed cholecystitis. In nine infants, spontaneous resolution occurred. In the absence of other clinical or imaging evidence of biliary tract disease, conservative management is advised.

Abstract
OBJECTIVE To study the prevalence of echogenic material in fetal gallbladder and to analyze its pathological relevance, the perinatal factors involved and the postnatal outcome of detected cases. PATIENTS AND METHODS We performed a prospective study of ultrasonographic examination of 9235 fetuses in the third trimester of gestation. Perinatal data were collected. Postnatal ultrasonography was performed in identified cases. RESULTS Fetal biliary echogenic material was found in 0.45 % of all pregnancies, with 42 identified fetuses. A single echogenic image was found in four fetuses (9 %), two or more echogenic images were found in seven fetuses (17 %) and biliary sludge was found in 31 fetuses (74 %). All diagnoses were made between weeks 29 and 38 of gestation. No link was found with maternal factors or perinatal abnormalities. Postnatal follow-up was carried out in 39 neonates; of these, five neonates (13 %) showed biliary sludge, although all five were asymptomatic. In further follow-up examinations, ultrasound studies were normal. CONCLUSIONS Fetal biliary echogenic material was found in one out of every 200 fetuses. No relationship was found with perinatal abnormalities. The prognosis of fetal gallstones and biliary sludge is favorable.

Abstract
BACKGROUND Conjugated jaundice arising during infancy may be caused by a number of different surgical conditions. The aim of this study was to compare clinical features, management, and outcome of all types of surgical jaundice presenting in the first year of life. METHODS A retrospective review was conducted of all infants born in the United Kingdom with jaundice caused by a surgical cause referred to the authors' institution from January 1992 to December 1999. RESULTS There were 171 infants who could be separated into 3 specific groups: biliary atresia (BA, n = 137), inspissated bile syndrome (IBS; n = 14), and choledochal malformation (CM; n = 12) together with a group containing various miscellaneous conditions (n = 8). Infants with BA had higher bilirubin (P <.01) and aspartate aminotransferase levels (P <.001) and came to surgery earlier (P <.01) than infants with either IBS or CM. Infants with IBS and CM were more likely to be premature and have other malformations, respectively. Ultrasound scan was the principal investigation in the differentiation of BA from other causes of jaundice. Accurate prelaparotomy diagnosis was made by percutaneous liver biopsy in 87% of cases later shown to be BA. Currently, 88 (64%) of children with BA are alive with their native liver postportoenterostomy, 4 have died, and 45 have undergone liver transplantation (with 1 death postoperatively). A policy of primary portoenterostomy for BA followed by transplantation, if necessary, resulted in a survival rate of over 95%. All children in the other diagnostic groups are alive and anicteric after appropriate surgical intervention. CONCLUSIONS Approximately 80% of infants presenting with surgical jaundice have biliary atresia, whereas those with inspissated bile syndrome and choledochal malformations make up most of the remainder. Mortality in this age-group is confined to infants with BA, but even on these infants an overall survival rate of greater than 95% is currently expected.

Abstract
A five-month-old infant of extremely low birthweight with choledocholithiasis is reported. A baby girl was delivered at 26 weeks gestation as a second twin, weighing 834 g. At 30 days of age, gallbladder stones were found by routine ultrasonography. She had vomiting at 157 days of age. Ultrasonography revealed calculi in the gallbladder and a dilated common bile duct. She was conservatively treated with scopolamine, antibiotics and dehydrocholic and ursodeoxycholic acids, and the calculi had disappeared by 189 days of age. Although conservative treatment succeeded in this patient, further cases should be analysed to establish how to manage choledocholithiasis in such small infants.

Abstract
Cholelithiasis in neonates and infants has been rarely reported. With the current widespread use of diagnostic ultrasonography, more neonates may be found with gallstones and common bile duct stones. We describe a case of asymptomatic gallstones detected incidentally at the age of four days who presented with early onset of neonatal sepsis and dehydration.

Abstract
BACKGROUND Gallstones and common bile duct calculi have been increasingly diagnosed in recent years in infants and children. The present study aims to review the spectrum of this disorder in the last two decades. METHODS During the period 1979-96 a total of 102 consecutive infants and children were diagnosed in Royal Alexandra Hospital for Children with gallstones or common bile duct calculi. A detailed retrospective analysis and follow-up of these children form the basis of the present report. RESULTS The median age at presentation was 10 years. Recurrent right upper quadrant pain was the most common clinical presentation. The male-to-female ratio was 3:2 and this male predominance was noted in all the age groups. Aetiologically three identifiable groupings were noted: idiopathic disease (n = 66), haematological diseases (n = 23) and specific non-haematological disease (n = 13). The incidence of idiopathic and haematological stones had increased two-fold in the second half of the study. The majority of children (86%) underwent surgical correction. Choledocholithiasis (CDL) was noted in 18 children (18%). Jaundice was commonly associated with abdominal pain in this group. A higher incidence of common bile duct calculi was noted in females and children less than 5 years of age (P < 0.01). Common bile duct calculi were accurately diagnosed by pre-operative imaging in all 18 children. Surgical correction was required in all except two. CONCLUSIONS The present study suggests an increasing incidence of gallstones in children. Cholelithiasis in children occurs commonly in boys, is idiopathic in aetiology and presents with a vague right upper quadrant pain. Choledocholithiasis is not uncommon in children, occurs more commonly in girls aged < 5 years and presents with jaundice or abnormal liver function tests.

Abstract
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.

Abstract
BACKGROUND/PURPOSE The longer-term sequelae of short bowel syndrome in infancy are reasonably well documented, but little is known about the long-term nutritional and metabolic effects of limited (less than 50 cm) ileal resection. This makes it difficult to formulate a rational follow-up policy in such children. METHODS All children who underwent limited ileal resection for either necrotizing enterocolitis (NEC) or intussusception at our institution between 1984 and 1992 were invited to attend a detailed clinical, anthropometric, hematologic, and biochemical assessment, together with a biliary and renal ultrasound scan and measurement of bone mineral density. RESULTS Twenty-four children (NEC, 17; intussusception, 7) of median age 7.4 years (range, 5.5 to 13.7 years) agreed to participate. Nine previously had undergone an isolated ileal resection, and 15 also had had variable lengths of colon removed. The length of resected ileum ranged from 3 to 44 cm, with a median of 10 cm. Seven control subjects in whom neonatal NEC developed but recovered without surgery were also evaluated. Median height, weight, and body mass index after ileal resection were between the 25th and 50th percentiles; no child was stunted or wasted. After ileal resection, one boy was found to have asymptomatic vitamin B12 deficiency, and three children had low plasma concentrations of vitamin A. Hematologic and biochemical parameters were otherwise normal apart from a few marginally low trace element levels in both subjects and controls. No renal calculi were detected, and bone mineral density measurements were normal in all except one child. Four children had cholelithiasis, all of whom had previously undergone limited ileal resection for NEC (two isolated, two ileocolic). Thus, the prevalence of cholelithasis after limited ileal resection for NEC was 24% at a median age of 7.0 years. CONCLUSIONS Growth and nutritional status are well preserved after limited ileal resection in infancy. Limited ileal resection for NEC is associated with a subsequent high prevalence of cholelithiasis and a risk of vitamin B12 deficiency. These findings are important when planning strategies for long-term follow-up.

Abstract
Three male fetuses examined sonographically in late gestation to assess growth and well-being were found to have evidence of gallbladder cholelithiasis. Postnatally, all three were asymptomatic but they had variable sonographic findings. In two, the abnormalities noted sonographically had resolved spontaneously by 6 weeks of age, but the third patient had a persistent gallbladder "calculus" at 6 months. All three boys, now aged 9 months to 4 years, remain well, with no evidence of biliary tract disease. Sonographic evidence of fetal gallbladder cholelithiasis may be found in late gestation, is more common among boys, and frequently is associated with benign spontaneous resolution.

Abstract
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.

Abstract
Down syndrome is a chromosomal disorder most often observed in the newborn period. Various facial, limb and internal abnormalities are found in this disorder but cholelithiasis in infancy has been described in only one report. We report two infants with Down syndrome associated with cholelithiasis. Except for polycythemia and indirect hyperbilirubinemia, no hemolytic process or biochemical abnormalities were evident in both patients. We believe that the cause of gallstones in our cases may have been polycythemia in the newborn period. To our knowledge this is only the second report of gallstones in infancy in Down syndrome.

Abstract
A case of calcification of the umbilical vein in a premature infant with nephrocalcinosis and cholelithiasis is described. Such an association might have resulted from prematurity, bronchopulmonary dysplasia, umbilical vein catheterization, total parenteral nutrition, and furosemide therapy. Follow-up ultrasound examination at 9 months of age revealed spontaneous resolution of calcification of both the gallbladder and the umbilical vein but not of the kidneys.
