Laparoscopic approach as primary treatment of common bile duct stones in children

Enhanced Recovery after Surgery Applied to Pediatric Laparoscopic Cholecystectomy for Simple Cholelithiasis: Feasibility and Teaching Insights

BACKGROUND

Same-day discharge after a cholecystectomy is a common practice in the adult population and has been demonstrated as safe and viable for children as well. However, there is a lack of comprehensive teaching models for pediatric cholecystectomy. Drawing inspiration from standardized outpatient procedures, this study aimed to assess the clinical outcomes and feasibility of teaching programs and an Enhanced Recovery After Surgery (ERAS) protocol following ambulatory laparoscopic cholecystectomy in pediatric patients.

METHODS

In 2015, an ERAS pathway for laparoscopic cholecystectomy (LC) was implemented, focusing on admission procedures, surgery timing, anesthetic choices, analgesia, postoperative feeding, mobilization, and pain assessment. Day-case surgery was not applicable for acute cholecystitis, choledochal lithiasis, sickle cell disease, and hereditary spherocytosis cases. The protocol was employed for a group of attending surgeons and fellows, as well as a group of residents under the supervision of experienced surgeons. A retrospective analysis was conducted to evaluate the feasibility and effectiveness of ambulatory cholecystectomy in children and its utilization in training pediatric surgical trainees.

RESULTS

Between 2015 and 2020, a total of 33 patients were included from a cohort of 162 children who underwent LC, with 15 children operated on by senior surgeons and 18 by young surgeons. The primary diagnoses were symptomatic gallbladder lithiasis (n = 32) and biliary dyskinesia (n = 1). The median age at the time of surgery was 11.3 years (interquartile range (IQR) 4.9-18), and the median duration of surgery was 54 min (IQR 13-145). One intraoperative complication occurred, involving gallbladder rupture and the dissemination of lithiasis into the peritoneal cavity. Three patients (9%) required an overnight stay, while no postoperative complications or readmissions within 30 days were observed. ERAS was successfully implemented in 30 patients (91%). No significant differences in surgical outcomes were noted between senior and young surgeons. At an average follow-up of 55 months, no long-term sequelae were identified.

CONCLUSIONS

These findings align with the current trend of increasing use of outpatient laparoscopic cholecystectomy and underscore its feasibility in the pediatric population. The application of a structured ERAS protocol appears viable and practical for training the next generation of pediatric surgeons.

Development of a risk score for choledocholithiasis in pediatric patients

PURPOSE

The prevalence of gallstones in children has increased over the last years. Choledocholithiasis (CD) is present in up to 30% of the cases. There is a scarcity of studies on the management of choledocholithiasis in children. The aim of this study was to develop a score that would allow predicting accurately the risk of CD in children with gallstones and reduce the number of non-therapeutic ERCP.

MATERIALS AND METHODS

We conducted a retrospective study in children with gallstones and suspected CD seen between January 2010 and December 2019. The main outcome was the presence of CD confirmed by at least one of the following diagnostic tests: magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and/or intraoperative cholangiography (IOC). We developed a risk score based on the presence or absence of the following risk factors: acute biliary pancreatitis, ascending cholangitis, elevated liver function tests (AST, ALT, total bilirubin [TB, ≥ 2 mg/dl], conjugated bilirubin, gamma-glutamyl transpeptidase, and alkaline phosphatase), CD on ultrasound (US; this was considered predictive but not confirmatory of CD), and dilation of the common bile duct (> 6 mm) by US. The score was divided into three different categories: low risk (no risk factors), intermediate risk (one risk factor present), high risk (≥ 2 risk factors present or ascending cholangitis). Given the main goal of reducing the number of diagnostic ERCPs, a very-high-risk subgroup (3 risk factors present or ascending cholangitis) was identified.

RESULTS

We reviewed 133 patients with gallstones and suspected CD. In 56 (42.1%) patients, the presence of CD was confirmed by one or more of the definitive diagnostic tests (MRCP, ERCP, and IOC). The following variables were found to be the strongest predictors of CD: ascending cholangitis, TB ≥ 2 mg/dl, common bile duct > 6 mm, and the presence of CD by US. The positive predictive value for CD was 7.5% in the low-risk group (OR 0.06, P = < 0.001); 22.9% in the intermediate-risk group (OR 0.31, P = 0.007); 77.6% in the high-risk group (OR 20.14, P = < 0.001); and 95.7% in very-high-risk subgroup (OR 49.18, P = < 0.001).

CONCLUSION

The risk score proposed in this study predicts accurately the presence of CD in children with gallstones. It can serve as a helpful tool to triage the need for costly and complex studies in the workup of CD, particularly in centers with limited resources. Finally, due to its high specificity and positive predictive value (PPV), the use of the very-high-risk criteria would allow for an important decrease in the number of non-therapeutic ERCP.

Asymptomatic Cholelithiasis in Children: Management Dilemma

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.

Pediatric Laparoscopic Common Bile Duct Exploration: An Opportunity to Decrease ERCP Complications

BACKGROUND

Laparoscopic intraoperative cholangiogram (IOC) with common bile duct exploration (CBDE) and endoscopic retrograde cholangiopancreatography (ERCP) are two therapeutic techniques for choledocholithiasis. The preferred technique is unclear.

MATERIALS AND METHODS

We identified subjects who underwent laparoscopic cholecystectomy (LC) and IOC/CBDE or ERCP from July 1, 2006, to December 31, 2016. We retrospectively reviewed 81 patients (≤ 18 y) who received these interventions for suspected choledocholithiasis. Main outcomes analyzed were success of intervention and complications.

RESULTS

Of the 81 patients, 21 ERCPs and three endoscopic ultrasounds (EUSs) were performed before LC. Eighteen of 21 (85.7%) patients had stones or sludge cleared by ERCP, whereas 3 (14.3%) had normal common bile ducts without evidence of stones. Five of 24 (20.8%) had significant post-ERCP complications. Seven of 24 (29.2%) had more than one admission. Sixty of 81 patients underwent LC with IOC ± CBDE. Twenty one of 60 (36.2%) were found to have abnormal IOC. Eight of 15 (53.3%) attempted laparoscopic CBDE were successful. Eleven of 21 (52.4%) patients with abnormal IOC had post-LC ERCP (10) and EUS (1). Patients admitted to the Pediatric Surgery service were more likely to undergo LC first than ERCP/EUS (OR 3.46, 95% CI 1.26 to 9.45, P = 0.016). Patients undergoing LC first had a shorter length of stay (mean LOS 5.13 d versus 4.07, median 5.0 versus 3.0 d, P-value < 0.05).

CONCLUSIONS

Successful and safe laparoscopic treatment of choledocholithiasis is possible in the pediatric patient. A laparoscopic-first approach to suspected choledocholithiasis may reduce the number of procedures needed in this patient population.

Percutaneous management of bile duct stones in children: results of 12 cases

PURPOSE

We aimed to evaluate the effectiveness of percutaneous transhepatic removal of bile duct stones in children.

METHODS

The study included 12 pediatric patients (4 males, 8 females; age range, 1-16 years; mean age, 6.6 years) who underwent percutaneous transhepatic removal of bile duct stones between September 2007 and December 2015. Demographic data, patient symptoms, indications for interventions, technical and clinical outcomes of the procedure, and complications were retrospectively evaluated.

RESULTS

Of 12 children, five children with cholelithiasis underwent cholecystectomy subsequently. The overall technical and clinical success rate was 100%. One patient had cholangitis as a complication during the follow-up and was treated medically.

CONCLUSION

Percutaneous transhepatic removal of bile duct stones is a safe and effective method for the treatment of children with biliary stone disease. It is a feasible alternative when the endoscopic procedure is unavailable or fails.

Laparoscopic versus endoscopic management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy: a meta-analysis

AIM

To compare the clinical effectiveness of the treatment of choledocholithiasis by laparoscopic common bile duct (CBD) exploration and by endoscopic sphincterotomy (EST).

MATERIALS AND METHODS

A meta-analysis of studies about CBD stones was performed to analyze EST in comparison with laparoscopic CBD exploration procedures. Trials were identified by searching the Medline, EMBASE, PubMed, CBM, and CNKI databases from January 1990 to December 2012 for laparoscopic CBD exploration or EST for CBD stones.

RESULTS

Fifteen studies were identified in the meta-analysis. The incidence of bleeding or pancreatitis in the EST group was higher than that in the laparoscopic group. However, the incidence of bile leakage in the EST group was lower than that in the laparoscopic group. The differences in cases of retained stones or total complications were not statistically significant between the laparoscopic and EST groups (P>.05). There were more successful cases in the laparoscopic group than in the EST group (P<.05). Hospital cost was less in the laparoscopic group than in the EST group (P<.05). Mean operation time and hospital stay in the laparoscopic group were shorter than those in the EST group (P<.05).

CONCLUSIONS

To some degree, laparoscopic treatment of the CBD may be a better way of removing stones than EST.

Safety and efficacy of one-stage total laparoscopic treatment of common bile duct stones in children

BACKGROUND

The purpose of this study is to confirm the effectiveness of total laparoscopic treatment of common bile duct (CBD) stones in children.

METHODS

All children who were treated in our department for cholelithiasis were reviewed from 1996 to 2013. Data collection focused on children with CBD stones, including age, sex, symptoms at diagnosis, hepatic and pancreatic blood tests results, US scan results, etiology, detailed surgical technique, operative time, length of hospital stay, complications, and stone-free status or not, at last follow-up.

RESULTS

551 children were treated for cholelithiasis and had undergone laparoscopic cholecystectomy. Among those, 36 children (6.5%) presented with CBD stones with a mean age at symptom onset of 10.4 years (min-max: 4 months-18 years). A majority of the patients presented with hemolytic disease (61%). In 55% of the cases, cholangiography alone or simple serum saline flush of the biliary tree was sufficient to obtain a stone-free CBD. Additional maneuvers with Dormia basket or Fogarty catheter led to 72% of success rate. In 9 cases (25%) of failure of the procedure, 6 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES), 1 patient was re-operated at day1 for hemorrhage, and 2 patients were followed by US scan with spontaneous evacuation of CBD stones. Mean follow-up was of 2 years (min-max: 1 month-5 years). All patients were stone free at last clinical and radiological evaluation.

CONCLUSION

A one-stage total laparoscopic treatment of common bile duct stones in children is a safe, feasible, reproducible, and efficient procedure in 72% of the cases. This rate could be upgraded by a combination of laparoscopic and endoscopic technique during the same anesthesia and preserving Oddi sphincter function. These minimal invasive techniques still need to be developed in children.

Laparoscopic techniques for safe and successful removal of common bile duct stones in pediatric patients

BACKGROUND/PURPOSE

Choledocholithiasis is uncommon in the pediatric population. Techniques for common bile duct stone extraction are still not well established. This article aims to describe safe and applicable techniques for pediatric common bile duct exploration.

MATERIALS AND METHODS

This was a retrospective review of a prospectively maintained database of two pediatric surgeons for patients undergoing laparoscopic common bile duct exploration at two tertiary-care centers from April 2008 to March 2012.

RESULTS

For 39 patients under 15 years of age undergoing laparoscopic cholecystectomy, 10 cholangiograms were performed, and 8 were found to have filling defects. Seven patients underwent successful laparoscopic common bile duct exploration with documentation of stone clearance, and 1 patient was sent for postoperative endoscopic retrograde cholangiopancreatography with stone extraction. Eleven patients had cholecystectomy performed by single-incision laparoscopic surgery, but none of these had cholangiograms or common bile duct explorations. Various methods of stone clearance were used, including the use of saline flush, balloon catheters, nitinol stone extractors, and the aide of glucagon. Depending on patient size, a choledochosope or a ureteroscope was used. There were no complications and no conversions to open surgery.

CONCLUSIONS

Laparoscopic common bile duct exploration is feasible in the pediatric population, using many of the instruments readily available in the standard operating room. With an armamentarium of tools and techniques, the method of stone extraction can be tailored to the patient and situation.

[Video-assisted surgery in children: current progress and future perspectives]

This review presents the evidence of video-assisted surgery in the pediatric population and discusses future progress in this field. Videosurgery minimizes the cosmetic impact and the pain induced by open procedures and has been in constant development in adults and children. Earlier training of surgeons and residents combined with advances in anesthetics and technology have expanded the use of videosurgery for more complex interventions. Although most feasible surgical procedures have been performed by laparoscopy, the literature has not yet defined it as the gold standard for most interventions, especially because of the lack of evidence for many of them. However, laparoscopy for cholecystectomy is now the preferred approach with excellent postoperative outcomes and few complications. Although no evidence has been demonstrated in children, laparoscopy has been shown to be superior in adults for gastroesophageal reflux disease and splenectomy. Laparoscopic appendectomy remains controversial. Nevertheless, meta-analyses have concluded in moderate but significant advantages in terms of pain, cosmetic considerations, and recovery for the laparoscopic approach. Laparoscopy is now adopted for undescended testes and allows both localization and surgical treatment if necessary. For benign conditions, videosurgery can be an excellent tool for nephrectomy and adrenalectomy. However, laparoscopy remains controversial in pediatric surgical oncology.

Laparoscopic common bile duct exploration in children is associated with decreased cost and length of stay: results of a two-center analysis

PURPOSE

Our aim was to compare outcomes of children undergoing laparoscopic cholecystectomy with laparoscopic common bile duct exploration (LC+CBDE) to those undergoing laparoscopic cholecystectomy with adjunctive endoscopic retrograde cholangiopancreatography (LC+ERCP).

METHODS

We performed a two-center retrospective chart review of all children (<18 years) undergoing LC+CBDE or LC+ERCP between January 2000 and July 2011. Wilcoxon test was performed on continuous variables and logistic regression modeling on categorical data. A P value < 0.05 was considered significant. Outcomes with a P value < 0.2 were selected for multivariable analysis.

RESULTS

Forty-two patients were identified. Twenty-four (57%) underwent LC+ERCP, and eighteen (43%) underwent LC+CBDE. Demographic and clinical factors were well matched between groups. Total operative time was similar between groups (157 min vs. 152 min, P = .26). LC+CBDE patients had zero major complications and five minor complications (retained stone: 3, pancreatitis: 1, late recurrence: 1). LC+ERCP patients experienced two major complications (duodenal perforation: 1, bleeding requiring transfusion: 1), and four minor complications (pancreatitis: 2, retained stone: 2, P = .57). Median length of stay was significantly longer (15.7 days vs. 6.6 days, P = .02), and median hospital cost was significantly higher ($18,132 vs. $12,735, P < .01) in the LC+ERCP group. Multivariable analysis revealed that cost was significantly lower in patients undergoing LC+CBDE (P = .05, OR= 0.71; 95% CI: 0.51-0.97).

CONCLUSION

LC+CBDE at the time of cholecystectomy is associated with decreased length of stay, decreased cost, and has similar or improved morbidity compared to LC+ERCP.

Management of choledochal cyst: Evolution with antenatal diagnosis and laparoscopic approach

BACKGROUND/AIM:

Laparoscopic excision of a choledochal cyst (CC) with hepaticojejunostomy gained a wide acceptance in the treatment of children even in neonatal period. Although, the use of prenatal diagnostic techniques causes a significant increase in antenatal diagnosis of CC, the time of surgical intervention during infancy is still controversial. A retrospective study was performed to evaluate the results of laparoscopic management of CC with special emphasis on antenatal diagnosis and treatment, and to compare the results with open procedure.

MATERIALS AND METHODS:

The patients who were diagnosed with choledochal cyst and underwent either open or laparoscopic hepaticojejunostomy in two centres, hopital d’enfant de La Timone from Marseille and hopital Robert Debre from Paris between November 2000 and December 2009 were included in the study. The data obtained from medical reports were evaluated for sex, time of antenatal diagnosis, age at time of operation, operative time, time of postoperation.

RESULTS:

A total of 19 hepaticojejunostomy were performed, including 10 open procedures (group A), and 9 laparoscopic procedures (group B, 4 were diagnosed prenatally, without conversion to open procedure). There were 3 boys and 16 girls, ranging in age from 2 weeks to 16 years. Patients in the group A were older than patients in the group B. The mean hospital stay and time to return of bowel fuction was longer in the group B. there were 60% of pre-operative complications in group A versus 22% in group B. There was one postoperative complications in group B (biliary leakage nedeed redo surgery). No significant differences were found between different parameters except for operative time (288.56 min in the group B versus 206 min in the group A. (p = 0.041)).

CONCLUSIONS:

Our initial experience indicates that the laparoscopic approach in infancy is technically feasible, safe, and effective, with a low morbidity and a comparable outcome to the open approach. Therefore, we propose a laparoscopic approach for antenatally diagnosed CC as early as possible, before the onset of complications.

Laparoscopic cholecystectomy in children with sickle cell anemia and the role of ERCP

BACKGROUND

Patients with sickle cell anemia (SCA) have a high incidence of cholelithiasis and choledocholithiasis. This report is an analysis of our experience with laparoscopic cholecystectomy (LC) for children with SCA and the role of endoscopic retrograde cholangiopancreatography (ERCP).

PATIENTS AND METHODS

The records of children with SCA who had cholecystectomy were retrospectively reviewed for age, sex, hemoglobin level, hemoglobin electrophoresis, indication for cholecystectomy, operative time, hospital stay, and postoperative complications. They were divided into 2 groups, open cholecystectomy (OC) group and LC group, and the 2 were compared in terms of operative time, hospital stay, and postoperative complications.

RESULTS

Over a period of 15 years (January 1995 and December 2009), 94 children with SCA had cholecystectomy. Thirty-five (19 males and 16 females) had OC, 52 (28 males and 24 females) had LC, and 7 (4 males and 3 females) had LC and splenectomy. Their age ranged from 4 to 15 years (mean, 11.4 y). The indications for cholecystectomy were biliary dyspepsia and biliary colic (55), acute cholecystitis (7), obstructive jaundice (17), asymptomatic (12), and biliary pancreatitis (3). All those who had OC underwent intraoperative cholangiogram, 9 of them (25.7%) had common bile duct (CBD) exploration and 2 transduodenal sphincterotomy. Of those who had LC, 13 (25%) underwent preoperative ERCP, which was normal in 1, showed dilated CBD with no stones in 2, and dilated CBD with stones in 7. In 3, ERCP showed dilated CBD with enlarged, inflammed papilla suggestive of recent stone passage. Nine underwent endoscopic sphincterotomy and stone extraction followed by LC. There was no mortality; 1 (2.1%) required conversion to OC and another underwent postoperative exploration because of bleeding from an accessory cystic artery. In the LC group, 4 (7.7%) developed minor postoperative complications, whereas 8 (22.9%) in the OC group developed complications.

CONCLUSIONS

With proper perioperative management, LC is feasible, safe, and superior to OC in children with SCA with regard to postoperative complications, duration of hospital stay, cosmetic appearance, and postoperative recovery. LC should be the treatment of choice for both symptomatic and asymptomatic cholelithiasis in children with SCA. ERCP is a valuable diagnostic and therapeutic investigation both preoperatively and postoperatively. The 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 with SCA.

Major bile duct injuries during cholecystectomy in children: conservative laparoscopic approach is possible

Major bile duct injury is an inherent complication in cases of both open and laparoscopic cholecystectomies. In case of choledochal lesion, conservative treatment or internal derivation by a Roux-en-Y can be proposed. We report the case of a 5-year-old boy referred to our center for an iatrogenic choledochal ligation after open cholecystectomy (performed 20 d before) for asymptomatic gallbladder stone. We performed a laparoscopic conservative treatment with a consistent good result 5 years after the procedure.

Laparoscopic pancreatic necrosectomy in a child with severe acute pancreatitis

Acute pancreatitis (AP) in children usually follows a mild course but occasionally may be severally problematic. We report the case of a 12-year-old boy with severe AP who was managed with repeated laparoscopic pancreatic necrosectomy. Three weeks later he represented with a pancreatic pseudocyst that was treated with endoscopic gastrocystotomy. His abdominal pain persisted and a subsequent magnetic resonance cholangiopancreatogram showed multiple gallbladder and common bile duct (CBD) stones that were missed on previous imaging investigations. He underwent laparoscopic cholecystectomy with transcystic exploration of the CBD. The patient is currently well, more than 2 years following the definitive corrective surgery. To the best of our knowledge, this is the first case of laparoscopic pancreatic necrosectomy in a child.

Laparoscopic exploration of the common bile duct to relieve choledocholithiasis in children

PURPOSE

The optimal method of managing paediatric choledocholithiasis is controversial. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy are effective in adults; however, the long-term outcome in the paediatric population is unknown. We report our experience with laparoscopic common bile duct (CBD) exploration to relieve choledocholithiasis in children and propose a management algorithm.

METHODS

A retrospective chart review of 124 children, who underwent cholecystectomy over 5 years was conducted. Data collected included age at onset, duration of symptoms, length of stay, method of relieving choledocholithiasis and postoperative outcome.

RESULTS

Mean age was 12.5 years (range 10-14 years). 102 cholecystectomies were performed laparoscopically. Following intraoperative cholangiogram (IOC), choledocholithiasis was identified in eight patients. In three cases, the CBD was flushed with normal saline via a 5F ureteral catheter successfully relieving the obstruction. In three cases, a Dormia basket was used to break down the stone. Two cases required postoperative ERCP and sphincterotomy to successfully extract the stones. All children were symptom-free at follow-up with no complications reported to date.

CONCLUSION

Laparoscopic CBD exploration with Dormia basket or saline flushes to relieve choledocholithiasis is a safe and effective alternative in children. If unsuccessful, ERCP and sphincterotomy can be performed in centres with adequate resources and expertise.

Safety and long-term outcomes of endoscopic papillary balloon dilation in children with bile duct stones

BACKGROUND

Although experience with diagnostic and therapeutic ERCP in children is growing, little is known about the safety and technical outcomes of endoscopic papillary balloon dilation (EPBD) in pediatric patients with bile duct stones (BDSs).

OBJECTIVE

To assess the safety and long-term outcomes of EPBD in pediatric patients with BDSs.

DESIGN

Case study.

SETTING

Tertiary referral center.

PATIENTS AND INTERVENTIONS

This study involved 5 children who had BDSs combined with gallstones who underwent EPBD.

MAIN OUTCOME MEASUREMENTS

Successful EPBD, successful stone removal, procedure-related complications, and long-term outcomes.

RESULTS

ERCP was successful in all cases, with cannulation and subsequent EPBD. Stone removal was performed in 1 session in all patients. No EPBD-related complications were observed in any patient. After EPBD, 1 patient subsequently underwent laparoscopic cholecystectomy for gallstones. The remaining 4 were followed without surgery. In 2 patients, gallstones were spontaneously passed from the bile duct into the duodenum. During the follow-up period, over a mean of 7.1 years (range 3.7-9.3 years), no recurrence of BDSs was observed in any patient.

LIMITATIONS

Small number of patients.

CONCLUSIONS

Although BDSs are rare in pediatric patients, EPBD may be a safe and effective technique for the management of such stones in some children.

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.

Minimally invasive surgery in the diagnosis and treatment of abdominal pain in children

PURPOSE OF REVIEW

Children with abdominal pain sometimes require surgical intervention, and laparoscopy is increasingly the preferred approach for the diagnosis and treatment of both acute and chronic abdominal pain in children. This review describes the current state of the art and recent developments in the application of minimally invasive surgical techniques for the treatment of children with various abdominal pain syndromes.

RECENT FINDINGS

Laparoscopy provides distinct advantages over traditional open surgery, including less pain, shorter recovery and improved cosmesis. Cumulative experience and ongoing outcomes research continue to substantiate the safety and efficacy of the approach when applied thoughtfully and by experienced practitioners. In fact, as minimally invasive surgery is being applied to treat more wide-ranging disorders, it is becoming apparent that for many conditions laparoscopy should be adopted as the standard of care.

SUMMARY

Recent advances in minimally invasive surgery have clearly benefited children with abdominal pain who need surgery, and as techniques improve and instruments get smaller we can expect this trend to continue into the future.

Choledocholithiasis: Evolving standards for diagnosis and management

Cholelithiasis, one of the most common medical conditions leading to surgical intervention, affects approximately 10 % of the adult population in the United States. Choledocholithiasis develops in about 10%-20% of patients with gallbladder stones and the literature suggests that at least 3%-10% of patients undergoing cholecystectomy will have common bile duct (CBD) stones.

CBD stones may be discovered preoperatively, intraoperatively or postoperatively Multiple modalities are available for assessing patients for choledocholithiasis including laboratory tests, ultrasound, computed tomography scans (CT), and magnetic resonance cholangiopancreatography (MRCP). Intraoperative cholangiography during cholecystectomy can be used routinely or selectively to diagnose CBD stones.

The most common intervention for CBD stones is ERCP. Other commonly used interventions include intraoperative bile duct exploration, either laparoscopic or open. Percutaneous, transhepatic stone removal other novel techniques of biliary clearance have been devised. The availability of equipment and skilled practitioners who are facile with these techniques varies among institutions. The timing of the intervention is often dictated by the clinical situation.
