ERCP and endoscopic sphincterotomy in infants and children with jaundice due to common bile duct stones

"Rendezvous" Procedure in Children with Cholecysto-Choledocholithiasis

Introduction: Cholecysto-choledocolithiasis is a rare entity in children and its management is still challenging and controversial. The laparoendoscopic rendezvous (LERV) procedure, consisting of laparoscopic cholecystectomy and simultaneous endoscopic retrograde cholangiopancreatography for the management of symptomatic choledocholithiasis is well described in adult patients. However, in the literature, few reports about its application in the pediatric population have been recorded. Aim of the Study: The aim of the present study is to report our first successful cases of symptomatic cholecysto-choledocholithiasis LERV treatment. Methods: Two girls suffering of hemolytic disease presented to our third referral center with acute abdominal pain due to cholecysto-choledocholithiasis. Preoperative, perioperative, and postoperative data were retrospectively reviewed. Results: Surgery was performed without complications. The girls were dismissed once re-alimentation and re-canalization were achieved and had no other episodes of biliary cholic. Reported advantages of LERV include: a shorter in-hospital stay, a reduction in the number of procedures and anesthesia, and a reduced overall risk of complications. Conclusions: The promising result with our 2 cases suggest that, when performed in highly specialized centers, LERV is a safe procedure, which leads to considerable benefits, despite logistic and organizational difficulties.

Endoscopic retrograde cholangiopancreatography in neonatal cholestasis

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is not as widely used in children as in adults and is performed in few specialized centers. The aim of the present study was to review the experience of ERCP in children younger than 3 months in a national referral center.

METHODS

A retrospective chart review was performed of all of the babies younger than 3 months who underwent ERCP between 2000 and 2010. Data on demographics, diagnosis, type of anesthesia, treatments, and complications were collected.

RESULTS

A total of 27 babies, 14 boys, were examined. Median age was 55 days (range 33-89). Ultrasound was normal in 16 infants, whereas others included small gallbladder (4), biliary stones (3), and dilated bile ducts (3). Thirteen infants underwent earlier liver biopsy, which was inconclusive. ERCP led to the diagnosis of biliary atresia in 13 infants who had subsequent surgery. In others, ERCP showed choledochal cyst (1), biliary stones (2), dilated bile ducts (1), and normal examination (6); there were 5 failures. The final diagnoses in our cohort were extrahepatic biliary atresia (15), biliary stones (5), neonatal hepatitis (4), choledochal cyst (1), paucity of intrahepatic bile duct (1), and congenital hepatic fibrosis (1). Diagnoses in the failed ERCP group included biliary atresia (2), bile duct paucity (1), and biliary stones (2). In 4 (19%) infants with clinical suspicion of extrahepatic biliary atresia, a normal ERCP ruled out the diagnosis and avoided an intraoperative cholangiogram. No complications, including pancreatitis, were reported.

CONCLUSIONS

ERCP in infants is feasible and has no complications. It may serve as an additional diagnostic tool in neonatal cholestasis in inconclusive cases and may prevent more invasive procedures. ERCP may be part of the algorithm of neonatal cholestasis when it is available and other investigations fail to confirm a diagnosis.

Endoscopic retrograde cholangiopancreatography is useful and safe in children

PURPOSE

Endoscopic retrograde cholangiopancreatography (ERCP) is a recognized diagnostic and therapeutic tool in the adult population. Its use in children has been more common in the last years. There are little data on safety and usefulness of that procedure in children. The aim of this study was to review the experience with ERCP in a tertiary university center dedicated to children.

METHOD

We conducted a retrospective chart review of patients seen at the Centre Hospitalier Universitaire Ste-Justine (Montreal, Quebec, Canada) who had undergone an ERCP between September 1990 and July 2007. Data on demographics, diagnosis, anesthesia type, treatments, and complications were collected.

RESULTS

Thirty-eight ERCPs were performed on 29 patients. There were 21 girls (72%), and median age at time of procedure was 10.3 years old (range, 3-17 years). Most had only one procedure performed. Two children had 2 interventions, and 1 child with papillary stenosis had 8 interventions linked to stent treatment. The ampulla was cannulated, and the procedure was successfully completed in 97% (37/38) of cases. General anesthesia and sedation were performed in 74% and 26% of procedures, respectively. Indications for ERCP were 29 recurrent or chronic pancreatitis (76%), 8 common bile duct obstructions (21%), and 1 choledochal cyst (3%). Endoscopic treatment was done in 29% of cases. The complication rate was 13.5%, and 4 clinical acute pancreatitis resolved with conservatory treatment. No severe pancreatitis, perforation, or bleeding was noted. Of the patients, 79% had their follow-up at the Centre Hospitalier Universitaire Ste-Justine for a median length of 43 months (range, 1-53 months).

CONCLUSION

Endoscopic retrograde cholangiopancreatography is used as a diagnostic and therapeutic procedure in children with a complication rate similar to that seen in adults. The need for general anesthesia is much more frequent with children. When performed by well-trained endoscopists, ERCP is useful and safe in children.

Endoscopic sphincterotomy is a useful preoperative management for refractory pancreatitis associated with pancreaticobiliary maljunction

BACKGROUND

Pancreatitis associated with pancreaticobiliary maljunction (PBM) is commonly treated nonoperatively before surgery. It is, however, sometimes uncontrollable, and little has been reported about the management.

METHODS

Focusing on the preoperative management, we reviewed clinical courses of 4 PBM cases (ages 1 to 7 years old). Each had pancreatitis that was totally resistant to medical treatment and was applied endoscopic sphincterotomy (ES).

RESULTS

The first case underwent percutaneous transhepatic catheter drainage (PTCD) primarily. In spite of daily lavage using the drainage tube for a week, plugs located in the common channel were not removed, and clinical findings were not improved. Therefore, ES followed by removal of protein plugs was performed to improve pancreatitis dramatically. Through this experience, 3 subsequent cases with refractory pancreatitis all underwent successful ES primarily soon after the medical treatments turned out to be ineffective. In all 4 cases, protein plugs were impacted in common channels, and ES could successfully remove the plugs that were impossible to remove by using PTCD. Improved preoperative pancreaticobiliary decompression by ES shortens the duration of recalcitrant acute pancreatitis associated with PBM allowing for a subsequent safe operation.

CONCLUSIONS

Endoscopic sphincterotomy is one of the useful preoperative managements for refractory pancreatitis associated with PBM.

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.

Choledocholithiasis in a 4-month-old infant

Cholelithiasis is increasingly being diagnosed in newborns and infants because of the more frequent use of abdominal ultrasound. However, common bile duct stones causing obstruction or symptoms in infancy are exceedingly rare and are not often reported in the literature. We report the successful treatment of symptomatic choledocholithiasis in a 4-month-old patient with endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy.

Diagnostic and therapeutic ERCP in the pediatric age group

The role and value of endoscopic retrograde cholangiopancreatography (ERCP) in the pediatric age group is not well established, because pancreatic and biliary diseases are less common in children. This however is not the case in areas like the Eastern Province of Saudi Arabia where sickle cell disease (SCD) and other hemoglobinopathies are common, with increased frequency of cholelithiasis and choledocholithiasis. The purpose of this study was to evaluate the indications, findings, safety and therapies of ERCP in children. One hundred and twenty five children had diagnostic and/or therapeutic ERCP as part of their management at our hospital. Their medical records were reviewed for: age at diagnosis, sex, Hb electrophoresis, indication for ERCP, findings, therapy and complications. There were 77 males and 48 females. Their age at presentation ranged from 5-18 year (mean 13.25 year). The majority of them had sickle cell disease (77.6%). The indications for ERCP were: obstructive jaundice (67.2%), recurrent biliary colic with or without jaundice (10.4%), acute and chronic pancreatitis (7.2%), postoperative bile leak (2.4%), cholangitis with obstructive jaundice (2.4%), hepatitis of unknown etiology (3.2%), cirrhosis of unknown etiology (4%), thalassemia with jaundice (0.8%), hemobilia (0.8%), acute cholecystitis with jaundice (0.8%), and sickle cell disease with ulcerative colitis and obstructive jaundice (0.8%). In six children, ERCP was done following laparoscopic cholecystectomy. ERCP was carried out under sedation in 91 (72.8%) children and under general anesthesia in 34. It was successful in 121 (96.8%) children while cannulation of the Ampulla failed in four. ERCP was normal in 43 children, but eight of them showed evidence of recent stone passage and in six, there were gallstones. In the remaining children, ERCP revealed: normal CBD with stones (18 patients), dilated CBD with stones (17 patients), dilated CBD without stones (19 patients), dilated biliary tree with stones (10 patients), dilated biliary tree without stones (six patients), bile leak (two patients), dilated biliary tree with stones and choledocho-duodenal fistula (one patient), choledochal cyst (two patients), septate gallbladder (one patient), normal ERCP with multiple pancreatic cysts (one patient) and biliary stricture (one patient). The following procedures were carried out: 35 had endoscopic sphincterotomy and stone extraction, 20 had endoscopic sphincterotomy, four had CBD stenting, one underwent removal of a stent, two had insertion of a nasobiliary tube and one had biliary endoprosethesis. There was no mortality. One had bleeding from the site of sphincterotomy which stopped after adrenaline injection. Four patients (3.2%) developed transient mild pancreatitis which settled conservatively. ERCP in the pediatric age group is safe both as a diagnostic and therapeutic procedure. ERCP can provide valuable information which aid in the diagnosis of biliary and pancreatic diseases in children as well as therapy with the technical feasibility of endoscopic sphincterotomy. This is specially so in the era of laparoscopic cholecystectomy, where ERCP should be the treatment of choice in children with CBD stones who are going or have previously undergone laparoscopic cholecystectomy.

Endoscopic management of sphincter of Oddi dysfunction in children

BACKGROUND

Data on sphincter of Oddi dysfunction (SOD) in children are scant. Most children diagnosed with SOD are treated by biliary sphincterotomy with suboptimal results. The efficacy and safety of pancreatic and dual sphincterotomy in children with SOD has not been previously reported.

OBJECTIVE

To evaluate the efficacy and safety of pancreatic and dual sphincterotomy in children with SOD.

MATERIALS AND METHODS

Prospective evaluation of all children who underwent endoscopic retrograde cholangiopancreatogram (ERCP) with sphincter of Oddi manometry for evaluation of suspected SOD over a 3-year period. Children diagnosed with SOD underwent pancreatic or dual sphincterotomy with prophylactic pancreatic stenting.

RESULTS

SOD was diagnosed by sphincter of Oddi manometry in 6 of 11 children who underwent ERCP for suspected SOD. Of the 6 children (mean age, 11 years; range, 5-16; 4 girls) with SOD, 3 presented with recurrent pancreatitis and 3 with postcholecystectomy pain. Pancreatic sphincter hypertension was noted in all 6 patients; concomitant biliary sphincter hypertension was noted in 3 patients with postcholecystectomy pain. Patients with recurrent pancreatitis underwent pancreatic sphincterotomy and those with postcholecystectomy pain underwent dual sphincterotomy. Prophylactic pancreatic stents were placed in all patients. One girl experienced mild post-ERCP pancreatitis. At a mean follow-up of 583 days (range, 325-1445), 4 patients were asymptomatic, 1 experienced partial symptom relief and 1 had recurrent symptoms.

CONCLUSIONS

As in adults, pancreatic and dual sphincterotomy, in expert hands, is effective and safe in a subgroup of children with SOD. Prospective, randomized trials with larger number of patients are required to validate the efficacy of endotherapy in children with SOD.

Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography in children: a large series report

OBJECTIVES

Our goal is to evaluate the indications, findings, therapies, safety, and technical success of endoscopic retrograde cholangiopancreatography (ERCP) in children.

METHODS

Our database was searched for patients 17 years of age or younger undergoing ERCP between January 1994 and March 2003. Additional information was obtained by chart review. The safety and technical success of ERCP were examined. Complications were classified by the consensus criteria.

RESULTS

A total of 245 patients (95 M, 150 F; mean age 12.3 years) underwent 329 examinations. Indications included biliary pathology (n = 93), pancreatic pathology (n = 111), and chronic abdominal pain of suspected biliary or pancreatic origin (n = 41). The ERCP findings were bile duct stone(s) (n = 29), benign biliary stricture (n = 19), primary sclerosing cholangitis (n = 7), anomalous pancreaticobiliary union (n = 8), choledochal cyst (n = 5), bile duct leak (n = 6), malignant biliary stricture (n = 2), biliary atresia (n = 1), chronic pancreatitis (n = 44), pancreas divisum (n = 26), pancreatic duct stricture with (n = 6) or without (n = 9) leak, pancreatic tumor (n = 1), periampullary adenoma (n = 2), and sphincter of Oddi dysfunction (n = 65). Endoscopic therapies were performed in 71% of the procedures and included sphincterotomy, stone extraction, stricture dilation, endoprosthesis placement, snare papillectomy, and cystoduodenostomy. Thirty-two (9.7%) post-ERCP complications occurred and included cholangitis in 1 patient and pancreatitis in 31. The pancreatitis was graded mild in 24, moderate in 5, and severe in 2. No mortality related to ERCP occurred.

CONCLUSIONS

Diagnostic and therapeutic ERCP results are similar in children and adults except for a lower incidence of malignant disease in children. Technical success rates are high. However, ERCP-related pancreatitis is not uncommon, and the risk and benefits should be carefully reviewed before proceeding. Outcome data are necessary and is currently being accumulated at our institution.

Acute biliary pancreatitis in a 9-year-old child treated with endoscopic sphincterotomy

Acute biliary pancreatitis is a well recognized complication of gallstone disease in adults. Acute pancreatitis in childhood is usually caused by congenital anomalies of the pancreatico-biliary ducts, viral infections, drug toxicity or abdominal trauma. We report the case of a 9-year-old girl with acute biliary pancreatitis and cholangitis. On urgent endoscopic retrograde cholangiopancreatography a bulging papilla with impacted stone was seen. She was treated with endoscopic sphincterotomy without complications. The disease resolved rapidly and uneventfully after the endoscopic treatment.

Endoscopic sphincterotomy in the management of bile duct stones in children

OBJECTIVE

Endoscopic sphincterotomy (ES) is a widely accepted method of extracting bile duct stones (BDS) in young as well as in elderly patients. The present study was undertaken to assess the safety and efficacy of ES for the treatment of BDS in children, seven of whom were critically sick because of suppurative cholangitis or pancreatitis.

METHOD

Over a period of 33 months, ES was performed in 16 consecutive children aged 7-16 yr with BDS. Nine patients had gallbladder in situ, and seven had previously undergone cholecystectomy. The coexisting abnormalities were gallstones and hepatic duct stones in one patient each and dead fragmented roundworms in 11 patients. Seven (five with an intact gallbladder and two cholecystectomized) patients presented with severe complications of BDS such as severe cholangitis in six and acute severe pancreatitis in one.

RESULTS

ES was technically successful in all patients, and complete stone extraction was achieved in 15 (93.8%) patients. Complications were minor bleeding in one (6.3%) patient without mortality. One patient with coexisting gallstones underwent cholecystectomy at a later date. During a mean follow-up period of 4-32 months, one patient developed recurrent biliary symptoms because of biliary ascariasis.

CONCLUSIONS

We conclude ES is a safe and an effective method of treating BDS in children with previous cholecystectomy, and in those presenting with severe complications of BDS, such as pyogenic cholangitis or acute pancreatitis regardless of the presence of gallbladder.

Endoscopic retrograde cholangiopancreatography in the management of pancreaticobiliary disorders in children

BACKGROUND AND AIM

The role of endoscopic retrograde cholangiopancreatography (ERCP) is not yet fully established in children. The purpose of this study was to assess the use of ERCP in the diagnosis and management of various pancreaticobiliary disorders in children.

METHODS

Eighty-four ERCPs were performed over 5.5 years in 72 children with suspected pancreaticobiliary tract disorders with an adult-type duodenoscope. In all cases, indications, procedure time, ERCP findings, complications, patients course and therapeutic intervention (if any) were recorded.

RESULTS

The mean (+/- SD) age of these children was 8.8 +/- 3.3 years. Successful cannulation was possible in 70 (97%) cases. Of the 44 cases with suspected biliary tract disease, 14 had a choledochal cyst, 13 had portal biliopathy, two each had CBD stones, primary sclerosing cholangitis and a bile leak, one had biliary ascariasis, eight had a normal cholangiogram, and CBD cannulation failed in two. Eight of the 28 children with suspected pancreatic disorders had chronic pancreatitis, five had pancreatic duct disruption, three had pancreas divisum and the rest had a normal pancreatogram (including all eight children with unexplained abdominal pain). Therapeutic ERCP was performed in 22 children, endoscopic nasobiliary or a nasocystic drain was placed in 16, biliary stenting was conducted in two, pancreatic duct stenting was conducted in three, and minor papilla dilation was conducted in one child. Six children had mild procedure-related complications.

CONCLUSION

Endoscopic retrograde cholangiopancreatography is very useful in the treatment of cholangitis, bile leak, pseudocyst and pancreatic fistulae in children. However, its role in unexplained abdominal pain is doubtful.

Pancreatitis caused by common bile duct stones in a 3-year-old boy with prior surgery for a choledochal cyst

Pancreatitis in children is uncommon. Compared to adults, pancreatitis in children is usually related to trauma, anatomic anomalies, infections, hereditary, and systemic disease, but not gallstones or alcohol. Most cases do not require endoscopic intervention. We report an unusual case of recurrent pancreatitis in a child related to common bile duct stones requiring endoscopic treatments after surgical treatment for choledochal cyst.

Endoscopic retrograde cholangiopancreatography in children: A surgeon's perspective

PURPOSE

The aim of this study was to review the indications, success rate, and complications of endoscopic retrograde cholangiopancreatography (ERCP) in the pediatric age group.

METHODS

From 1990 to 1999, 21 ERCP procedures were attempted in 20 patients. They consisted of 8 boys and 12 girls whose age ranged from 4 to 17 years (mean, 11.3 years). Fourteen were performed under deep sedation (mean age, 12.8 years), and 7 were done under general anesthesia (mean age, 7.6 years). All ERCP procedures were performed by experienced adult endoscopists.

RESULTS

The indication for ERCP was biliary in 15 patients. Eleven had suspected choledocholithiasis by either ultrasound scan, intraoperative cholangiogram or magnetic resonance imaging (MRI). In 6 cases, the ERCP was done for pancreatic pathology. In 11 patients, the ERCP was diagnostic only, and in 10 a therapeutic procedure was done. The overall success rate was 90.5%. Post-ERCP complications consisted of 6 episodes of pancreatitis (28.5%), 4 of which followed a therapeutic procedure, and 1 episode of bleeding. Pancreatitis resolved 2 to 6 days post-ERCP. The patients underwent follow-up between 2 and 56 months after the ERCP (mean, 11 months).

CONCLUSIONS

The authors conclude that even in experienced hands, ERCP in the pediatric population has a much higher complication rate than in adults (33.3%). We recommend that very specific indications be met before subjecting a pediatric patient to an endoscopic retrograde cholangiopancreatography.

Therapeutic ERCP in the management of pancreatitis in children

BACKGROUND

The use of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is increasing in the management of pancreatobiliary diseases in children.

METHODS

Over a 32-month period, we performed 34 ERCP procedures for the treatment of pancreatitis in 22 children at two university hospitals. Demographics and clinical data and ERCP findings were documented. Clinical status was assessed 6 months before the first ERCP and 6 months after the last ERCP, according to general condition, severity and frequency of pain, and health care encounters (emergency department visits, clinic visits, and hospital admissions related to the pancreatitis).

RESULTS

Mean age of the patients was 10.7 years (range 1.5 to 17 years). Abdominal pain was the main presenting symptoms with hyperamylasemia and hyperlipasemia. Clinical diagnoses included acute pancreatitis (6), recurrent pancreatitis (5), and chronic pancreatitis (11). The mean follow-up was 16.4 months. Nine patients had sphincter manometry, with abnormal results leading to biliary sphincterotomy in 4. Fifteen patients underwent a total of 23 therapeutic ERCP procedures unrelated to sphincter dysfunction. There were 2 complications of 34 procedures (6%), both being mild pancreatitis after sphincter manometry. There were no deaths. There was a significant reduction in frequency (p < 0.01) and severity of pain (p < 0.01) after intervention. Patients without pancreatographic changes of chronic pancreatitis had the most marked clinical improvement (p < 0.05). In those with ductal changes of chronic pancreatitis, clinical improvement was not predicted by the extent of ductal changes. There was a significant decrease in health care encounters (p < 0.05) and improvement in general condition (p < 0.01) after endoscopic therapy, especially in those with a normal pancreatogram.

CONCLUSIONS

Therapeutic ERCP is safe in pediatric patients with pancreatitis. Significant clinical improvement is achieved in patients with biliary or pancreatic stone disease. Prospective studies with long-term follow-up are needed to determine the impact of endoscopic therapy in patients with chronic pancreatitis and sphincter of Oddi dysfunction.

ERCP in the management of pediatric pancreatitis

BACKGROUND

Although ERCP is commonly performed in children, the effect of findings at ERCP on the subsequent management of pediatric pancreatitis is unknown.

METHODS

We retrospectively reviewed charts to determine the impact of ERCP on the management of recurrent acute or chronic pancreatitis in 17 consecutive children (3 boys and 14 girls, 3 to 16 years, mean 11.2 years) with recurrent acute (n = 13) or chronic pancreatitis (n = 4) who underwent ERCP. Radiographs were reviewed in a blinded manner, and the effect of ERCP findings on subsequent management was determined.

RESULTS

In 16 of 17 patients (94%), the pancreatic duct was successfully visualized. Of the 16 studies, 9 (56%) had abnormal findings. A change in therapy occurred in all 9 patients as a result of the findings at ERCP. Of the 7 patients with a prior abnormal CT or ultrasound, 5 (71%) had an abnormal ERCP, all resulting in a change in therapy. Three of the 9 patients (33%) without radiographic abnormalities had an abnormal ERCP that, in each case, resulted in a change in therapy. Overall, findings at ERCP altered therapy in 52% of pediatric patients studied with recurrent acute or chronic pancreatitis. A prior abnormal CT had a high predictive value with respect to ERCP resulting in a change in management (83%).

CONCLUSIONS

ERCP is useful in the management of pediatric recurrent acute or chronic pancreatitis; abnormalities are found at a rate similar to those found in adults.

Sequential endoscopic/laparoscopic management of cholelithiasis and choledocholithiasis in children who have sickle cell disease

BACKGROUND/PURPOSE

Cholelithiasis and choledocholithiasis are common complications of sickle cell disease (SCD). With the recent advances in laparoscopic cholecystectomy (LC), which has been used successfully for the management of cholelithiasis in children who have SCD, exclusion of choledocholithiasis before LC is of great importance.

METHODS

Eighteen children who had SCD, cholelithiasis, and choledocholithiasis were treated at our hospital. Seven were treated with open cholecystectomy (OC) and common bile duct (CBD) exploration, and two were treated with transduodenal sphincteroplasty. The remaining 11 patients underwent endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and stone extraction followed by laparoscopic cholecystectomy (LC).

RESULTS

A dilated CBD noted on ultrasound, elevated alkaline phosphatase, elevated total bilirubin of more than 5 mg/dL, history of pancreatitis, either singly or in combination, should raise suspicion of choledocholithiasis, and these patients together with those who have choledocholithiasis detected on ultrasound should undergo ERCP to confirm and extract the stones before LC.

CONCLUSION

This sequential approach of endoscopic sphincterotomy and stone extraction followed by LC is a safe and effective approach for the management of cholelithiasis and choledocholithiasis in children who have SCD.

The management of choledocholithiasis in children in the era of laparoscopic cholecystectomy

Although laparoscopic cholecystectomy has become the procedure of choice for gallbladder removal in children, the treatment of children who have choledocholithiasis remains unclear. For adults who have suspected choledocholithiasis, preoperative endoscopic retrograde cholangiopancreatography (ERCP) is a well-described and effective approach, however, its use for common bile duct stones in children has not been defined. The authors reviewed the records of 131 consecutive children undergoing laparoscopic cholecystectomy on two surgical services to define the efficacy of ERCP followed by laparoscopic cholecystectomy in managing choledocholithiasis in children. Fourteen children were suspected of having common duct stones noted on preoperative ultrasound scan and laboratory data. At ERCP, six children had no stones visualized; eight had stones and underwent stone extraction and sphincter dilation or sphincterotomy. All 14 underwent laparoscopic cholecystectomy a mean of 3.8 days after ERCP. None of the 14 had evidence of retained stones. Only one of 117 children undergoing primary laparoscopic cholecystectomy had unsuspected common bile duct stones and was treated with laparoscopic common bile duct exploration and stone removal. A management plan incorporating ERCP followed by early laparoscopic cholecystectomy is a safe and effective strategy for children who have choledocholithiasis.

Multidisciplinary approach to the treatment of pediatric pancreaticobiliary disorders

A multidisciplinary approach using traditional open surgery, endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery has revolutionized the care of the adult with pancreaticobiliary disease. This study focuses on a similar collaborative effort to diagnose and treat children with pancreaticobiliary disorders. Charts of all patients treated on the pediatric surgery service between June 1990 and May 1995, who also underwent ERCP, were abstracted for disease process, presenting symptoms, laboratory evaluation, surgical or endoscopic procedures, and eventual outcome. Twenty-six children were identified, ranging from 6 months to 19 years of age. Pancreaticobiliary disorders included pancreas divisum (n = 1), choledochal cyst (n = 4), pancreaticobiliary trauma (n = 4), cholelithiasis and choledocholithiasis (n = 17). The pancreaticobiliary tree was successfully visualized by ERCP in 25 of 26 (96%) patients. Fifteen of these patients also underwent attempted therapeutic endoscopic procedures, with 13 (87%) performed successfully. Three patients with choledochal cyst had stents placed preoperatively for cholangitis, all of whom have undergone successful choledochal cyst excision. Two trauma patients underwent attempted stenting of a bile leak and bile duct stricture, respectively, both of which were unsuccessful, necessitating surgical correction. Seventeen patients with cholelithiasis underwent ERCP to rule out choledocholithiasis. Ten patients were found to have common duct stones, and all stones were endoscopically extracted, including those in a 6-month-old child. Overall survival rate was 96% (25 of 26), with the one death occurring in a trauma patient unrelated to his pancreaticobiliary disorder. A multidisciplinary approach using traditional open surgery, ERCP and laparoscopic surgery can successfully treat even young children with pancreaticobiliary disorders. In experienced hands, diagnostic ERCP and therapeutic endoscopic intervention can be performed successfully in most pediatric patients, greatly simplifying the surgical management of these potentially complex problems.

The role of ERCP in the diagnosis and treatment of idiopathic recurrent pancreatitis in children and adolescents

ERCP was performed in 51 patients, aged 1 to 18 years, as part of diagnostic evaluation for recurrent pancreatitis without obvious cause or as therapeutic intervention. ERCP was successful in 50 patients (98%). Thirty-four patients (68%) had anatomic findings indicating a possible cause of recurrent pancreatitis. Three patients (6%) had findings suggestive of sphincter of Oddi dysfunction. Eighteen of the 37 patients (49%) with ductal abnormalities underwent endoscopic therapy, with a favorable outcome in 15 (83%). Eleven patients were treated surgically, and 8 of these patients (73%) improved symptomatically. Eight patients received no treatment, and 6 of them (67%) had recurrent bouts of clinical pancreatitis. One mild case of pancreatitis (1.9%) occurred after ERCP, and 3 mild cases followed endoscopic therapy. In conclusion, ERCP is a relatively safe technique that produces opacification of the desired ductal system with a high degree of accuracy and provides useful information in the evaluation of children with idiopathic recurrent pancreatitis. These data suggest that endoscopic pancreatic therapy may result in symptomatic improvement, eliminating the need for surgery in selected children. Furthermore, the study demonstrates that manipulation of the pancreatic duct is comparatively safe and less hazardous than formerly believed.
