Selective intraoperative cholangiography during laparoscopic cholecystectomy in children is justified

Comparison of laparoscopic cholecystectomy in children at paediatric centres and adult centres: a systematic review and meta-analysis

INTRODUCTION

Paediatric laparoscopic cholecystectomy (LC) is performed by both paediatric and adult surgeons. The aim of this review was to compare outcomes at paediatric centres (PCs) and adult centres (ACs).

METHODS

A literature search was conducted, in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, for papers published between January 2000 and December 2020. Statistical analysis was performed using Stata® version 16 (StataCorp, College Station, TX, US).

RESULTS

A total of 92 studies involving 74,852 paediatric LCs met the inclusion criteria. Over half (59%) of the LCs were performed at ACs. No significant differences were noted in the male-to-female ratio, mean age or mean body mass index between PCs and ACs. The main indications were cholelithiasis (34.1% vs 34.4% respectively, p=0.83) and biliary dyskinesia (17.0% vs 23.5% respectively, p<0.01). There was no significant difference in the median inpatient stay (2.52 vs 2.44 days respectively, p=0.89). Bile duct injury was a major complication (0.80% vs 0.37% respectively, p<0.01). Reoperation rates (2.37% vs 0.74% respectively, p<0.01) and conversion to open surgery (1.97% vs 4.74% respectively, p<0.01) were also significantly different. Meta-analysis showed no significant difference in overall complications (p=0.92).

CONCLUSIONS

The number of LCs performed, intraoperative cholangiography use and conversion rates were higher at ACs whereas bile duct injury and reoperation rates were higher at PCs. Despite a higher incidence of bile duct injury at PCs, the incidence at both PCs and ACs was <1%. In complex cases, a joint operation by both paediatric and adult surgeons might be a better approach to further improve outcomes. Overall, LC was found to be a safe operation with comparable outcomes at PCs and ACs.

Clinical Utility of Definitive Diagnostic Tests for Choledocholithiasis in Pediatric Patients with Mild Gallstone Pancreatitis

BACKGROUND

Gallstone pancreatitis was historically considered a risk factor for choledocholithiasis (CD). However, recent studies of adult patients evidenced a weak association between gallstone pancreatitis and CD. The aim of this study was to analyze this association in pediatric patients.

METHODS

We conducted a retrospective study on patients with mild gallstone pancreatitis who underwent any definitive testing for CD (MRCP, ERCP, IOC), managed between March 2010 and September 2022. Patients were classified according to the presence or absence of risk factors for CD (total bilirubin ≥2 mg/dl; common bile duct >6 mm on ultrasound; and/or CD on ultrasound). We evaluated the diagnosis of CD on definitive testing in both groups and analyzed the predictive capacity of the presence of risk factors.

RESULTS

Eighty-four patients were included in the final analysis. Seventy-nine percent were females. The median age was 13 (4-17) years. Forty-seven (55.9%) patients had one or more risk factors. The definitive testing confirmed 13 (15.5%) cases of CD, 12 (25.5%) in the group of patients with risk factors and 1 (2.7%) in those without risk factors. The sensitivity, specificity, positive predictive value and negative predictive value of the presence of associated risk factors were 92.3, 50.7, 25.5 and 97.3%, respectively.

CONCLUSION

Pediatric patients with gallstone pancreatitis without associated risk factors have a very low incidence of CD. In these patients we suggest performing a laparoscopic cholecystectomy without intraoperative cholangiography or any other definitive test for CD.

The Use of Intraoperative Cholangiography During Cholecystectomy: A Systematic Review

Cholecystectomy is a widespread surgical procedure for gallbladder diseases. Evolving techniques and technologies, such as intraoperative cholangiography (IOC), enhance safety and outcomes by providing real-time biliary system visualization during surgery. This systematic review explored available data on using IOC during cholecystectomy, highlighting its effectiveness, safety, and cost-effectiveness. To perform this systematic review, a thorough literature search was conducted using relevant keywords in electronic databases, such as PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Library, Web of Science, and Google Scholar. We included studies published during the last 10 years exploring the use of IOC during cholecystectomy. The findings showed success rates of up to 90% with a median time of 21.9 minutes without complications. Most (90%) patients with acute gallstone pancreatitis underwent cholecystectomy with IOC, with unclear IOC results in 10.7% and failure in 14.7%. IOC failure factors included age, body mass index (BMI), male sex, concurrent acute cholecystitis, common bile duct (CBD) stone evidence on imaging, CBD diameter of >6 mm, total bilirubin of >4 mg/dL, abnormal liver tests, and gallstone pancreatitis. The detection of choledocholithiasis by IOC prompted trans-cystic duct exploration and endoscopic retrograde cholangiopancreatography (ERCP). Biliary abnormalities and stone identification were observed using IOC, and routine use increased bile duct stone detection while decreasing bile duct injury and readmission rates. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of IOC for common bile duct stone detection were reported at 77%, 98%, 97.2%, 63%, and 99%, respectively. Routine IOC was projected to provide substantial quality-adjusted life years (QALY) and cost-effectiveness gains compared to selective IOC. Regarding safety, IOC was generally associated with reduced complication and open surgery conversion risks, with similar rates of CBD injury and bile leaks. These findings indicate that IOC enhances cholecystectomy outcomes through precision and decreasing complications.

Tips and Tricks—3 Use Cases of Interdisciplinary Knowledge Transfer in Minimally Invasive Pediatric Surgery

In the pediatric surgical environment, we can enrich our knowledge and improve our skills through interdisciplinary knowledge transfer in exchange with other surgical or even non-surgical disciplines. To demonstrate this, we present in this article three patient cases of method transfer enabling new techniques in minimally invasive pediatric surgery. 1. The somewhat modified application of the AeroStat rigid tip laparoscopic cholangiography catheter during the single-step laparoscopic cholecystectomy facilitates the safe intraoperative cholangiography with common bile duct flushing. 2. A magnetic rod is used during laparoscopic enterotomy to locate and retrieve ingested magnets. 3. Using a patient-specific MRI 3D model representing a syndromic high anorectal malformation improves surgical planning and parental education.

Utility of routine intraoperative cholangiogram during cholecystectomy in children: A nationwide analysis of outcomes and readmissions

PURPOSE

This study aims to determine postoperative outcomes and readmissions in pediatric cholecystectomy with routine intraoperative cholangiogram (IOC) utilization.

METHODS

The Nationwide Readmissions Database 2010-2014 was queried for all pediatric cholecystectomies. A propensity score-matched analysis (PSMA) with over 30 covariates was performed between cholecystectomy alone (CCY) versus those with routine IOC (CCY + IOC, no biliary obstruction, dilatation, or pancreatitis). χ² analysis or Mann-Whitney U were used for statistical analysis with p < 0.05 set as significant.

RESULTS

34,390 cholecystectomies were performed: 92% were laparoscopic, most were teenage females (75%, 15 years [13-17]) and did not undergo IOC (75%). Postoperative mortality rate was 0.1%. The PSMA cohort comprised of 1412 CCY and 1453 CCY + IOC. Patients with CCY alone had higher rates of 30-day (7% vs 5%), 1-year readmissions (13% vs 11%) and had higher rates of overall complications (22% vs 12%) compared with CCY + IOC, all p < 0.05. Although uncommon, bile duct injuries were more prevalent in CCY (2% vs 0%, p < 0.001), while there was no difference in readmissions for retained stones. Resource utilization was increased in CCY patients, likely due to increased complication rates.

CONCLUSION

This nationwide PSMA suggests pediatric CCY with routine IOC is associated with decreased readmissions, overall resource utilization, complications, and bile duct injuries.

[Biliary tract surgery in childhood]

In contrast to gallstones, which are increasingly diagnosed in children and adolescents, congenital or perinatally acquired malformations of the biliary tree are rare entities. The surgical treatment of these diseases frequently represents a technical challenge. For children with biliary atresia Kasai portoenterostomy is a therapeutic option in the first weeks of life. Most affected children, however, require a liver transplantation before they enter adulthood. Segmental dilatations of the bile duct carry the risk of ascending infections and malignant transformation. This requires early resection of the biliary tree and reconstruction with a bilioenteric anastomosis. While laparoscopic cholecystectomy has become the standard approach also for children, the value of minimally invasive procedures for more complex surgical procedures of the biliary tract has not yet been defined.

Impact of Children's Hospital Designation on Outcomes and Costs after Cholecystectomy in Adolescent Patients

Variations in the management of adolescents at children's hospitals (CHs) and nonchildren's hospitals (NCHs) have been well described in the trauma literature. However, the effects of CH designation on outcomes after common general surgical procedures have not been investigated. The purpose of this study was to compare the outcomes and costs of adolescent cholecystectomies performed at CHs and NCHs. Within the California State Inpatient Database (2005–2011), we identified 8117 cholecystectomy patients aged 13 to 18 years at CHs and NCHs. Outcomes (laparoscopy, intraoperative cholangiogram, length of stay (LOS), and complications) and costs were analyzed. CHs cared for younger patients, more uninsured patients, and more black patients. NCHs were associated with higher laparoscopy use (95.7% vs 88.3%, P < 0.01), higher intra-operative cholangiogram rates (28.8% vs 11.9%, P < 0.001), shorter LOS (3.2 vs 5.0 days, P < 0.01), and lower costs by $5797 per patient ($11,219 vs $17,016, P < 0.01). Although there was no significant difference in overall complication rates, CHs had higher rates of infectious complications (2.0% vs 1.0%, P = 0.004). Adolescent cholecystectomies are safely performed at NCHs while achieving increased laparoscopy use, shorter LOS, and lower costs compared with CHs.
