Modifications in endoscopic practice for pediatric patients

Efficacy and safety of intravenous thiamylal in sedation for colonoscopy in children

Objectives

Since a standard sedation protocol for pediatric colonoscopy (CS) has not been established, evidence on optimal sedative agents is needed. This study aimed to evaluate the efficacy and safety of thiamylal in sedation for pediatric CS compared to midazolam.

Methods

Children from 7 to 16 years of age who underwent CS under sedation with intravenous thiamylal or midazolam at our hospital between June 2010 and March 2024 were included in this retrospective observational study. The primary outcome was the efficacy (success rate of CS without mid-awakening) of the drugs. Meanwhile, the secondary outcomes were the sedation level during CS, procedure time, recovery time, and adverse events related to sedation.

Results

Sixty children were included in the study. The success rate of CS without mid-awakening was significantly higher in the thiamylal group (90.6%) than in the midazolam group (64.3%; p = 0.03). The two groups had no significant differences in median sedation depth, procedure time, or recovery time. Adverse events related to sedation in thiamylal group (22%) and midazolam group (25%) were similar. No severe adverse events were reported.

Conclusions

Intravenous thiamylal provides effective and safe sedation in children requiring CS, with little or no mid-awakening during the procedure.

Efficacy and safety of a new low-volume PEG with citrate and simethicone bowel preparation for pediatric elective colonoscopy: Phase 3 RCT

Background and study aims Currently available polyethylene glycol (PEG)-based preparations continue to represent a challenge in children. The aim of this study was to compare the efficacy and safety of a new low-volume PEG preparation with a conventional PEG-electrolyte solution (PEG-ES) in children and adolescents. Patients and methods This was a multicenter, randomized, observer-blind, parallel-group, phase 3 clinical trial, where patients were randomized between PMF104 (Clensia) and a conventional PEG-ES (Klean-Prep), and stratified by age stratum (2 to <6; 6 to < 12;12 to <18 years). The primary endpoint was to test the non-inferiority of PMF104 versus PEG-ES, in terms of colon cleansing. Safety, tolerability, acceptability, palatability, and compliance were also assessed. Efficacy endpoints were analyzed in the per protocol set (PPS) and full analysis set (FAS) and safety and tolerability endpoints in the safety set (SAF). Results Of the 356 patients enrolled, 258 were included in the PPS, 346 in the FAS, and 351 in the SAF. Non-inferiority of PMF104 was confirmed for children aged > 6 years and for all age groups in PPS and FAS, respectively. Optimal compliance was reported more frequently in the PMF104 than in the PEG-ES group, in both PPS (86.1% vs. 68.4%) and FAS (82.9% vs. 65.3%). Both preparations were equally safe and tolerable. Palatability and acceptability were considered better in the PMF104 group than in the PEG-ES group (27.1% vs. 15.3% and 15.3% vs. 3.5%, respectively). Conclusions In children aged 6 to 17 years, the new low-volume product PMF104 is non-inferior to the reference PEG-ES in terms of bowel cleansing, safety, and tolerability, with slightly better results in compliance, palatability, and acceptability.

Pediatric esophagogastroduodenoscopy in china: indications, diagnostic yield, and factors associated with findings

Background

Large-scale data on esophagogastroduodenoscopy (EGD) in China are scarce. This study aimed to assess the indications and diagnostic yield of EGD in children and the relationship between factors (such as age, sex, and indications) and diagnostic yield.

Methods

We performed a prospective cross-sectional observational study involving patients aged < 18 years who underwent diagnostic EGD. The study was conducted in five children’s hospitals, each in a different city. Demographic features, indications for endoscopy, and endoscopic and histopathological findings were collected. Univariable and multivariable ordinal logistic regression analyses of the relationship between the factors and diagnostic yield were performed.

Results

The study included 2268 patients (male/female ratio, 1.3:1) with a median age of 8.68 years. Among the 2268 children, the most frequent indications were abdominal pain in 1954 (86.2%), recurrent vomiting in 706 (31.1%), weight loss in 343 (15.1%), and others. The endoscopic yield was 62.5% and was the highest in patients with dysphagia (90.9%). The histologic yield was 30.4% and was the highest in patients with unexplained anemia (45.5%). On multivariable regression analysis, the endoscopic yield was associated with dysphagia, gastrointestinal (GI) bleeding, and recurrent vomiting, and the histologic yield was associated with age. Different groups of patients with abdominal pain had variable probabilities of abnormal endoscopic findings.

Conclusions

The most frequent indication of pediatric EGD is abdominal pain, with variable probabilities of abnormal endoscopic findings in different groups. Endoscopic yield and histologic yield are associated with certain alarming features.

Trial registration

The trial registration number (ClinicalTrials. gov): NCT03603093 (The study was registered on 27/07/2018).

Eesophagogastroduodenoscopy in paediatrics: does abiding by the international guidelines lead to appropriate management? A cross-sectional study

Objectives Esophagogastroduodenoscopy (EGD) is one of the most practiced procedures in paediatric gastroenterology. As with all other procedures, it is guided and controlled by specific guidelines developed and approved internationally. The European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) and the American Society for Gastrointestinal Endoscopy (ASGE) guidelines are two of the most followed guidelines in paediatric gastroenterology. This study aimed to determine how optimal patient condition management is when following international paediatric gastroenterology guidelines and to correlate the appropriateness of EGD and other variables with positive or negative findings on EGD.

DESIGN

A cross-sectional retrospective cohort of all first-time diagnostic upper endoscopies was conducted between 1 January 2016 and 1 February 2020, in Prince Hamzah Hospital in Jordan.

PARTICIPANTS

Paediatric patients between 9 months and 14 years of age with indications for EGD.

RESULTS

Overall, 529 diagnostic EGDs were performed during the study period. Helicobacter pylori-associated gastritis was the most common final diagnosis in 247 patients (47%). Furthermore, 488 (92%) EGDs were deemed appropriate, while 41 (7.7%) were considered inappropriate. Finally, 74.0% of all biopsies performed had positive contributive findings.

CONCLUSIONS

Abiding by international guidelines in paediatric gastroenterology can optimise care for paediatric patients. General paediatricians are urged to follow guidelines rigorously when referring patients to minimise inappropriate procedures.

Are biopsies always necessary in upper and lower gastrointestinal endoscopy in children? A retrospective 10-year analysis

Little attention has been given to the efficiency and validity of performing routine endoscopic biopsies in normal areas in children. This study aimed to investigate the need to perform routine biopsies in upper gastrointestinal endoscopy (UDE) and colonoscopy in normal areas by comparing macroscopy and histology. It was a 10-year retrospective analysis with the inclusion of 761 UDEs and 177 colonoscopies. Considering all segments, UDEs showed false-positive result rates of 73.11% and false-negative result rates of 14.34%. The histological results modified the initial management in 53.95% of patients. Considering all segments, colonoscopies showed false-positive result rates of 63.64% and false-negative result rates of 30.97%. The histological results modified the initial management in 34.45% of patients.Conclusion: If biopsies were obtained only in abnormal areas, the diagnosis would be lost in 53.95% of the patients in upper endoscopies and 85.7% of the colonoscopies, which justifies routine maintenance of biopsies in macroscopically normal areas in children. What is Known: • Little attention has been given to the efficiency and validity of endoscopic biopsies of normal areas during pediatric exams. • Only a few pediatric studies have correlated macroscopic and histological findings from endoscopic biopsies, and low sensitivity and specificity, as well as poor agreement, were reported. What is New: • Our study confirms the evidence that routine biopsies from macroscopically normal areas during upper and lower digestive endoscopies can lead to histopathological diagnoses and different medical management. • This is the first research on this topic in a Latin population, from a developing country, reassuring the results obtained in previous papers from other countries.

Pancreatobiliary Endoscopic Interventions for Pediatric Pancreatic Pathology

Despite the increased global recognition of pediatric pancreatic diseases, there are limited data on the utility of sophisticated endoscopic procedures such as endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in their management. Promising results of recent studies have highlighted the emerging therapeutic utility of EUS and ERCP in children. With these latest developments in mind, this article reviews the current literature regarding diagnostic and therapeutic uses, benefits, limitations, and clinical outcomes of EUS and ERCP in pediatric pancreatology.

Split dose versus full single-dose regimen of polyethylene glycol for bowel preparation in pediatric colonoscopy: a pilot study of randomized controlled trial

OBJECTIVES

Previous meta-analyses in adults comparing a full single dose vs. split doses of polyethylene glycol with electrolyte solution demonstrated that the split-dose group had a higher rate of successful bowel preparation. To date, no similar study in children has been conducted. Therefore, we compared the efficacy of bowel preparation between the two regimens of polyethylene glycol with electrolyte solution in pediatric colonoscopy. The secondary outcomes were tolerability, acceptability, and compliance.

METHODS

An investigator-blinded randomized controlled trial was conducted to enroll children aged 2-18 years who underwent an elective colonoscopy at a teaching hospital between March 2018 and February 2019. Patients were randomly assigned to receive polyethylene glycol with electrolyte solution as a full single dose or two split doses. The Boston Bowel Preparation Scale was used for the efficacy (i.e. successful bowel preparation if score ≥ 6). Secondary outcomes were evaluated by using a standardized questionnaire.

RESULTS

A total of 45 colonoscopies (22 in the full single-dose and 23 in the split-dose group) were performed. Mean age was 9.2 years old (SD 4.4). We noted a higher rate of successful bowel preparation in the split-dose group (95% vs. 72%, P = 0.047). Significant higher rate of willingness to repeat the same protocol (83% vs. 36%, P = 0.002) and a trend of lower rate of nausea/vomiting (39% vs. 68%, P = 0.051) in the split-dose group were found.

CONCLUSION

The split-dose regimen of polyethylene glycol with electrolyte solution for bowel preparation suggests superior efficacy, potential tolerability, and acceptability as compared to the traditional full single-dose regimen.

Algorithm to Predict Which Children With Chronic Abdominal Pain Are Low Suspicion for Significant Endoscopic Findings

Chronic abdominal pain (CAP) is a common and challenging problem in pediatric primary and specialty care. We developed a diagnostic algorithm to organize workup for gastrointestinal causes of CAP and improve identification of patients who are low suspicion (LS) or high suspicion (HS) to have significant intestinal pathology identified with endoscopy. We retrospectively used this algorithm to categorize 150 outpatients with CAP as LS (n = 99) or HS (n = 51) and examined subsequent endoscopic findings for all patients. There were 6% significant diagnoses in the LS group compared with 34% in the HS group ( P < .0001). The LS group had no patients with celiac or inflammatory bowel disease. These results can be used to help a clinician approach CAP, and discuss with families the likelihood of endoscopy finding a cause for CAP based on LS or HS designation.

The emerging role of endoscopic ultrasound for pancreaticobiliary diseases in the pediatric population

BACKGROUND

Endoscopic ultrasound (EUS) is a useful diagnostic and therapeutic tool in the pediatric population. Given the high accuracy and sensitivity of EUS, it is particularly effective in evaluating pancreaticobiliary disease. Published literature in the use of pediatric EUS is limited. Therefore we aimed to review the current literature for EUS indications, safety, and effectiveness for the pediatric population.

DATA SOURCES

English language articles on the use of pediatric endoscopic ultrasound in evaluating pancreaticobiliary diseases were retrieved from PubMed/ MEDLINE.

RESULTS

We analyzed various retrospective studies and case series publications. Data were extrapolated for pediatric patients with pancreaticobiliary diseases.

CONCLUSIONS

EUS offers superior imaging. It is comparible to magnetic resonance imaging and/or pancreatic-protocol computed tomography. In the current literature, there are a variety of pancreaticobiliary conditions where EUS was utilized to make a diagnosis. These include recurrent pancreatitis, congenital anomalies, microlithiasis, pancreatic pseudocysts, and pancreatic mass lesions. EUS was shown to be a safe and cost-effective modality with both diagnostic and therapeutic capabilities in the pediatric population. EUS is now increasingly being recognized as a standard of care when evaluating pancreaticobiliary conditions in children.

Validation of Adapted Dartmouth Operative Conditions Scale for sedation during pediatric esophagogastroduodenoscopy

AIMS

Pediatric esophagogastroduodenoscopy requires deep sedation as it involves stimulation of the airway. Frequency of adverse events is higher with esophagogastroduodenoscopy. Hence, monitoring needs sedation scales like the Dartmouth Operative Condition Scale that identifies safe states of sedation. This study aims at validating the Adapted Dartmouth Operative Condition Scale for sedation rating by pediatricians during pediatric esophagogastroduodenoscopy.

METHODS

Items in the Dartmouth Operating Conditions Scale were adapted for pediatric esophagogastroduodenoscopy. Videos of 35 procedures were recorded. The recording started 10 min before sedation and continued till recovery. The videos were split into preprocedure videos, intraprocedure videos, and recovery videos, and further split into 30-s clips. Twenty representative intraprocedure videos clips were selected. Ten raters scored the videos with the Adapted Dartmouth Operating Conditions Scale and modified-COMFORT score. The Adapted Dartmouth Operating Conditions Scale scoring was repeated after a month. The preprocedure videos, intraprocedure videos, and recovery videos of ten patients (six clips each) were scored by one rater to assess responsiveness.

RESULTS

The Adapted Dartmouth Operating Conditions Scale detected nonoptimal sedation states including laryngospasm due to undersedated states. It showed fair interrater reliability at timeline-1 (intraclass correlation coefficient = 0.45) and timeline-2 (intraclass correlation coefficient = 0.65) but poor intrarater reliability (intraclass correlation coefficient = 0.32). There was significant positive correlation with modified-COMFORT (Spearman's rank order correlation, r = 0.150). Responsiveness was demonstrated by the difference in the preprocedure videos, intraprocedure videos, and recovery videos scores (F = 126.50).

CONCLUSION

The Adapted Dartmouth Operating Conditions Scale detects nonoptimal sedation states during pediatric-esophagogastroduodenoscopy. It shows good criterion validity, interrater reliability, and responsiveness. Poor intrarater reliability seen in our study could be due to item ambiguity arising from the mode of training of the raters in the Dartmouth Operating Conditions Scale.

Endoscopic ultrasound with or without fine-needle aspiration has a meaningful impact on clinical care in the pediatric population

Background and Objectives:

The safety and utility of endoscopic ultrasound (EUS) for the evaluation and management of gastrointestinal (GI) tract disorders among adults has been established. The literature on safety and efficacy in a pediatric referral population (under 21 years of age) is limited. We hypothesized that EUS is safe and useful in the pediatric population. We reviewed the pediatric EUS experience at a single tertiary-care system. We describe the indications, findings, safety, technical success rate, and impact on clinical outcomes.

Patients and Methods:

All patients 21 years of age or younger referred for EUS between 5, 2007 and 11, 2012 were identified from our electronic medical record databases. Retrospective chart review was then conducted to document demographics, procedure indications, procedure type (diagnostic or therapeutic), type of anesthesia used, EUS findings, and the clinical impact of EUS on the subsequent management of the patients.

Results:

Seventy EUS procedures were attempted in 58 patients during the study. Of these, two EUS procedures were aborted due to inadequate moderate sedation and 68 were successfully completed. The median age at initial endoscopy was 18 years (range 6–21 years), 50% were male and 65% were Caucasian. Four patients underwent EUS-guided pseudocyst drainage. Among the remaining 54 patients, the indications for EUS were the evaluation of GI mucosal/submucosal lesions (n = 14), acute or recurrent pancreatitis (n = 10), localization of suspected insulinoma (n = 8), evaluation of pancreatic abnormalities seen on prior imaging (n = 6), surveillance of tumors or evaluation of luminal lesions in hereditary syndromes (n = 6), abdominal pain of suspected pancreatobiliary origin (n = 5), and other rare indications (n = 5). Fine-needle aspiration was performed in 13 (9 diagnostic, 4 therapeutic) and trans-gastric fine-needle contrast injection of the pancreatic duct was performed in one patient without any complications. Sedation (data available for 66 procedures) included general endotracheal anesthesia in 38 (57%), monitored anesthesia care (MAC) in 19 (29%), and moderate sedation in 9 (14%). There were 4 minor intra-procedural anesthesia-related complications (laryngospasm in 2 and hypoxemia from airway obstruction and secretions in 2) in MAC and general endotracheal anesthesia (GA) cases, and 1 postprocedural complication (fever after pseudocyst drainage). EUS can achieve the diagnostic or therapeutic goal and ruled out suspected pathology in 88% of cases precluding need for additional testing.

Conclusions:

(1) EUS in the pediatric population is technically successful and efficacious. (2) Therapeutic and diagnostic EUS impacted clinical care decisions. (3) There is a low risk of immediate significant complications. (4) The overall efficacy and safety support the performance of EUS in a pediatric population by experienced endoscopists.

[Intestinal cleaning for colonoscopy in children: effectiveness, adherence and adverse effects of schemes differentiated by age]

Adequate intestinal cleanliness is crucial to achieve optimal colonoscopy performance. Several bowel preparation (BP) schemes have been proposed, but there is still no consensus as regards which is the most suitable in paediatric patients.

OBJECTIVE

To describe the effectiveness, adherence, and adverse effects of BP protocols differentiated by age group in paediatric patients subjected to colonoscopy.

PATIENTS AND METHOD

Prospective, study that included patients < 18 years subjected to colonoscopy. BP protocols differentiated by age group were indicated as follows: < 6 m (glycerine suppository); 6 m-3y 11 m (poly-ethylene-glycol (PEG 3350 without electrolytes); 4y-9y 11 m (PEG 3350 without electrolytes + bisacodyl); 10 y-18 y (PEG 3350 with electrolytes). Demographic, clinical information, adherence and adverse effects were registered. Effectiveness was determined using a validated scale (Boston modified) during colonoscopy.

RESULTS

A total of 159 patients were included, of which 87 (55%) were males, and with a median age of 4 years (range 1 m-17 years). Seventy eight percent of patients achieved successful BP. The higher effectiveness was observed in the groups of < 6 m (96%) and 10-18 y (91%). Constipation was significantly more frequent (29%) in the 4 yo-9 yo 11 m in which lower effectiveness was observed (69%). Good adherence was observed in 87% of patients. Adverse effects were observed in a third of patients, although they were mild and did not lead to the suspension of the BP.

CONCLUSIONS

Satisfactory results were achieved with the BP schemes used, with a successful BP being obtained in 4 out of 5 patients. Results were different between groups, which is probably related to previous bowel transit and indicated medication.

Morphological and Functional Assessment of Oesophageal Mucosa Integrity in Children With Cystic Fibrosis

OBJECTIVES

The aim of the study was to investigate morphological and functional characteristics of oesophageal epithelial barrier in children with cystic fibrosis (CF) with or without gastro-oesophageal reflux disease (GORD) in comparison to healthy controls.

METHODS

Oesophagogastroduodenoscopy with oesophageal biopsies and combined oesophageal multichannel intraluminal impedance-pH monitoring was performed in 17 children with CF (CFtot) with (CFgord) or without GORD (CFnorm). Histological combined severity score was calculated and widths of spaces between epithelial cells were measured. Basal impedance value was used to assess functional integrity of epithelial barrier. Results of each investigation were compared with a group of children without oesophageal disease.

RESULTS

CFtot, but also CFnorm, had more severe pathohistological changes included in the compound severity score than controls (0.75 ± 0.32 and 0.75 ± 0.20 vs 0.27 ± 0.25; P < 0.001 and P = 0.001, respectively). They also had more dilated intercellular spaces (2.6 μm ± 0.6 and 2.7 μm ± 0.5 vs 1.9 μm ± 0.2; P = 0.001 and P < 0.001, respectively). Baseline impedance values between proximal and distal pairs of electrodes were significantly lower in CFtot (2876 Ω ± 484, 2590 Ω ± 1013) and also in CFnorm (2922 Ω ± 363, 2844 Ω ± 457) than in controls (3703 Ω ± 859, 3753 Ω ± 1070) (P = 0.012 and P = 0.002; and P = 0.027 and P = 0.005, respectively). The treatment of CFgord with proton pump inhibitor increased, but did not normalise the baseline impedance values (2860 Ω ± 560 to 3355 Ω ± 750 and 2178 Ω ± 1564 to 3057 Ω ± 594).

CONCLUSIONS

Children with CF had morphological and functional changes of oesophageal mucosal integrity even in the absence of GORD.

Current status and clinical impact of pediatric endoscopy in Korea

BACKGROUND/AIMS

In pediatrics, endoscopic examination has become a common procedure for evaluation of gastrointestinal presentations. However, there are limited data on pediatric endoscopy in Korea. The aim of this study was to analyze the current status and clinical impacts of endoscopic examination in children and adolescents.

METHODS

We retrospectively reviewed the medical records of outpatients who visited the tertiary hospital. Patients under 18 years of age who underwent endoscopy were included. Endoscopic findings were classified as specific and normal based on gross findings. Specific endoscopic findings were reflux esophagitis, peptic ulcers, and Mallory-Weiss tear. Other findings included acute gastritis classified according to the updated Sydney system.

RESULTS

In 722 of 330,350 patients (0.2%), endoscopic examination (554 esophagogastroduodenoscopies [EGDs], 121 colonos-copies, 47 sigmoidoscopies) was performed between January 2008 and January 2013. In EGD, abdominal pain was the most frequent presentation (64.1%). The most common diagnosis was gastritis (53.2%), followed by reflux esophagitis. The frequency of peptic ulcer disease was 12.8%. Frequent symptoms leading to colonoscopic examination were abdominal pain, diarrhea, and hematochezia. In colonoscopy, a negative result was more likely in children younger than 7 years old. After the procedure, the diagnostic yield of EGD and colonoscopy was 88.1% and 45.8%, respectively, and the rate of change in management was 67.1%.

CONCLUSIONS

In pediatrics, endoscopic examination was useful for the choice of therapeutic strategy and it would be a standard method for evaluation of gastrointestinal presentation.

Paediatric gastrointestinal endoscopy: a qualitative study

OBJECTIVE

Gastrointestinal endoscopy is an invasive procedure used to diagnose and/or treat diseases of the gut. As with any invasive procedure, there is a small risk for complications, and it is therefore important that due consideration be taken when reviewing the indications for endoscopy, particularly in children. Despite this, there remains a wide variation nationally in clinical practice among paediatric gastroenterologists. In the absence of a standard, we critically reviewed current endoscopy practice at Addenbrooke's Hospital with the aim of creating robust measures that could be used to achieve and maintain an efficient, high-quality paediatric endoscopy service. Specifically, we assessed the proportion of referred patients undergoing endoscopy and the clinical outcomes of these procedures.

DESIGN

A retrospective list of new clinic patients who had undergone endoscopy within 3 months of their appointment was obtained, dating from 1 January 2011 to 31 December 2011. Individual electronic medical records (eMR) records were reviewed for the type of endoscopy, indications, interval to procedure, histology findings, diagnoses, and impact on management.

RESULTS

Out of the 674 children seen at clinic over the year, 17% (n=114) went on to have an endoscopic procedure; half of these patients underwent both upper endoscopy (i.e., oesophagogastroduodenoscopy) and colonoscopy. Out of the children who underwent colonoscopy, 43% (n=25) were confirmed to have inflammatory bowel disease.

CONCLUSION

Our results provide a useful initial reference point against which other tertiary units can assess their own practice, with all striving to provide appropriate, efficient and cost-effective endoscopy services for children.

Comparison of rigid and flexible endoscopy for removing esophageal foreign bodies in an emergency

BACKGROUND/PURPOSE

Despite the effectiveness of endoscopies in removing ingested foreign bodies (FBs) impacted in the esophagus, the merits and limitations of flexible endoscopy (FE) and rigid endoscopy (RE) remain unclear. Therefore, this study compares the advantages and disadvantages of both endoscopic procedures from a clinical perspective.

METHODS

A retrospective review was made of 273 patients suspected of esophageal FBs in emergency consultations of a tertiary medical referral center from March 2010 to March 2014. All patients received routine physical examinations, otolaryngological examinations, and X-rays of the neck and chest. The door-to-endoscopy time, procedure time, postendoscopic hospital stay, successful removal rates, and complications were analyzed as well.

RESULTS

In this study, the most common esophageal FBs were fish and animal bones (76%) in adults and coins (74%) in children. The patients with existing esophageal FBs had significantly more frequent symptoms of dysphagia and signs of linear opacity as detected with lateral neck radiography than those without FB. Additionally, the door-to-endoscopy time, procedure time, and postendoscopic hospital stay was significantly shorter in FE patients than in RE patients. However, both RE and FE patients had high rates of successful FB removal (95%) and low complication rates (2%).

CONCLUSION

Both FE and RE remove esophageal FBs successfully, as evidenced by their high success rates, low complication rates, and high detection rates. Although FE under local anesthesia is a less time-consuming procedure for adults, RE under general anesthesia may be preferable for children and can serve as an alternative to FE.

Propofol-ketamine and propofol-fentanyl combinations for nonanesthetist-administered sedation

OBJECTIVES

There is a need to compare propofol requirement between propofol-ketamine (PK) and propofol-fentanyl (PF) given as nonanesthetist-administered propofol sedation during pediatric esophagogastroduodenoscopy (EGD).

METHODS

The study was a parallel-group, randomized, double-blind comparison of the need for additional doses of propofol in the first minute after sedation induction between PK and PF, administered by rotating trainees in pediatrics for sedation during pediatric EGD. A total of 95 children with American Society of Anesthesiologists class I to III between 3 and 12 years undergoing EGD were included and randomized to either of the groups. After midazolam premedication, children received either 0.5 mg/kg ketamine (PK) or 1 μg/kg of fentanyl (PF) followed by a mandatory 1 mg/kg of propofol. Additional doses of propofol of 0.5 mg/kg each were given to achieve sedation induction (modified Ramsay scale level 6), and further doses were administered during the procedure as required. A total of 92 children (PK, n = 47; PF, n = 45) were analyzed. P < 0.05 was considered significant.

RESULTS

There was no difference in the propofol dose required for successful scope introduction and also in the need for additional propofol doses and the total additional propofol doses required in the first minute after sedation induction. Propofol injection pain was higher in the PF group (odds ratio 1.78). The adverse events and recovery time were similar. There was no escalation of care, airway intubations, death, or disability.

CONCLUSIONS

Nonanesthetist-administered propofol sedation is feasible in teaching hospitals. Propofol requirement is similar in both PK and PF combination regimens, but the lower frequency of propofol injection pain may favor the use of PK.

A survey of procedural sedation for pediatric gastrointestinal endoscopy in India

BACKGROUND

Sedation practices for pediatric gastrointestinal endoscopic procedures (PGEP) vary based on infrastructure, availability of trained personnel, and local protocols. Data on prevalent sedation practices is lacking from India. This study aimed to survey the sedation practices for PGEP in India.

METHODS

A mailing list was constituted with the e-mail addresses of the members of the Indian Society of Pediatric Gastroenterology, Hepatology and Nutrition, Indian Academy of Pediatrics, Association of Surgeons of India, Indian Association of Pediatric Surgeons, and Indian Society of Gastroenterology. The web-based survey was sent by e-mail.

RESULTS

Of the 498 recipients, who responded through the survey link, 91 did not complete the survey. Among those who completed the survey, 91 performed PGEP. Among these 91, 12.1 % performed PGEP without sedation or general anesthesia. Anesthetist involvement was associated with use of propofol based-sedation. Of the respondents, 70.3 % found non-anesthetist administered propofol sedation unacceptable while 38.5 % of the centers had a policy against it. Two-thirds of the respondents were assisted by an anesthetist for most PGEP. An operating room (OR) was used for PGEPs by 23.1 %. PGEP in a non-teaching hospital, non-availability of pediatrician in the endoscopy room, use of an OR for PGEP, and the easy availability of an anesthetist were strongly associated with the involvement of an anesthetist.

CONCLUSIONS

The survey indicates a high frequency of involvement of anesthetists and use of OR. This survey should serve as an impetus to evaluate the cost of PGEP in India and the training accorded to non-anesthetists for procedural sedation.

The therapeutic use of endoscopic ultrasonography in pediatric patients is safe: A case series

BACKGROUND/AIM

Despite the safety and high diagnostic yield of endoscopic ultrasound guided fine needle aspiration (EUS FNA) for the evaluation of gastrointestinal diseases in adults, literature discussing the therapeutic use of EUS FNA in pediatrics remains limited. This study reports our experience with the use of EUS in children with pancreaticobiliary disorders.

PATIENTS AND METHODS

A retrospective study was conducted to evaluate safety, clinical utility, and impact of therapeutic EUS on the management of children (<18 years) at a tertiary referral center. Data were collected from January 1, 2011, to April 30, 2014. Patient demographics, clinical characteristics, and EUS procedure data were reviewed. Continuous variables were described using the mean and standard deviation. Categorical variables were described using frequencies and percentages.

RESULTS

A total of 6 therapeutic EUS procedures were performed in 5 children (3 F/2 M). The mean age was 13 years (range 6-17) with a mean body mass index of 28.2 (range 18.5-38.8). The indications for EUS procedures were abdominal pain with chronic pancreatitis (3) and management of symptomatic pancreaticobiliary cysts/pseudocysts observed on previous imaging (3). All procedures were performed under general anesthesia. The 6 therapeutic procedures performed were celiac plexus block (3), cyst gastrostomy with stents placement (2), and cyst aspiration using EUS FNA (1). A celiac plexus block effectively relieved abdominal pain in 2 patients with chronic pancreatitis. Cyst gastrostomy successfully resulted in pseudocyst resolution in the follow up imaging of 2 patients (up to 6 months after the procedure). Cyst aspiration with EUS guided FNA resulted in cyst resolution and confirmation of the benign nature of the cyst in 1 patient. All the procedures were successfully completed with no reported complications.

CONCLUSION

The therapeutic use of endoscopic ultrasound in the pediatric population is safe and has a high success rate.

Bowel preparations for colonoscopy: an RCT

BACKGROUND

The ideal preparation regimen for pediatric colonoscopy remains elusive, and available preparations continue to represent a challenge for children. The aim of this study was to compare the efficacy, safety, tolerability, and acceptance of 4 methods of bowel cleansing before colonoscopy in children.

METHODS

This randomized, investigator-blinded, noninferiority trial enrolled all children aged 2 to 18 years undergoing elective colonoscopy in a referral center for pediatric gastroenterology. Patients were randomly assigned to receive polyethylene glycol (PEG) 4000 with simethicon (PEG-ELS group) or PEG-4000 with citrates and simethicone plus bisacodyl (PEG-CS+Bisacodyl group), or PEG 3350 with ascorbic acid (PEG-Asc group), or sodium picosulfate plus magnesium oxide and citric acid (NaPico+MgCit group). Bowel cleansing was evaluated according to the Boston Bowel Preparation Scale. The primary end point was overall colon cleansing. Tolerability, acceptability, and compliance were also evaluated.

RESULTS

Two hundred ninety-nine patients were randomly allocated to the 4 groups. In the per-protocol analysis, PEG-CS+Bisacodyl, PEG-Asc, and NaPico+MgCit were noninferior to PEG-ELS in bowel-cleansing efficacy of both the whole colon (P = .910) and colonic segments. No serious adverse events occurred in any group. Rates of tolerability, acceptability, and compliance were significantly higher in the NaPico+MgCit group.

CONCLUSIONS

Low-volume PEG preparations (PEG-CS+Bisacodyl, PEG-Asc) and NaPico+MgCit are noninferior to PEG-ELS in children, representing an attractive alternative to high-volume regimens in clinical practice. Because of the higher tolerability and acceptability profile, NaPico+MgCit would appear as the most suitable regimen for bowel preparation in children.

The safety of propofol sedation for elective nonintubated esophagogastroduodenoscopy in pediatric patients

OBJECTIVES

To evaluate the safety of deep sedation provided by pediatric intensivists for elective nonintubated esophagogastroduodenoscopy.

DESIGN

Retrospective observational study.

SETTING

The sedation program at the Helen DeVos Children's Hospital.

PATIENTS

A 4-year retrospective analysis was done on all outpatient elective pediatric esophagogastroduodenoscopy procedures performed in an intensivist run sedation program. Safety was examined by reviewing the occurrence of minor and major adverse effects during esophagogastroduodenoscopy sedation. Interventions were studied and reported.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

During the study period, 12,447 sedations were performed by the pediatric sedation program for various procedures. Two thousand one hundred forty-seven patients received 2,325 sedations (18.6%) for esophagogastroduodenoscopies performed for various indications. During the same time period, 53 (one for every 40 esophagogastroduodenoscopy sedations) were screened, found unsuitable for nonintubated sedation, and referred for general anesthesia. There were 2,254 sedations with propofol, 65 methohexital, five ketamine, and one fentanyl/midazolam sedation. Propofol sedation proved safe with a 2.1% prevalence of minor adverse events and no major events. Methohexital, on the other hand, had higher rate (p < 0.001) of minor events and one patient developed an anaphylactic reaction to its use. Regression analysis showed that other sedative agents were 8.6 times more likely to be associated with complications than propofol (odds ratio, 8.6; 95% CI, 4.1-18.2; p < 0.001).

CONCLUSIONS

This study demonstrates that deep sedation for elective esophagogastroduodenoscopies can be provided safely in the appropriately screened patient by nonanesthesiologist physicians in a sedation program. These data suggest that propofol is a safe and effective agent for esophagogastroduodenoscopy sedation.

Utility of Narrow Caliber Echo-bronchoscope in Pre-school Pediatric Population: A case series (with video)

The practical use of EUS in small children below the age of 4 years is not described. The aim of the study was to evaluate the feasibility, safety, and clinical utility of smaller caliber echo-bronchoscope in the management of gastrointestinal, pancreatobiliary, and mediastinal disease in children below 4 years. Consecutive children of age younger than 4 years where EUS was clinically considered useful were evaluated by echo-bronchoscopes. The findings showed that EUS by echo-bronchoscopes is feasible and safe in young children.

Good agreement between endoscopic findings and biopsy reports supports limited tissue sampling during pediatric colonoscopy

OBJECTIVES

Colonoscopy in children routinely includes the practice of obtaining multiple biopsy samples even in the absence of gross mucosal abnormalities. The aim of our investigation was to examine the level of agreement between endoscopic and histological findings during pediatric colonoscopy. We also investigated the predictors of agreement and abnormal histology.

METHODS

We performed an institutionally approved retrospective review of consecutive patients who underwent diagnostic colonoscopy during a 6-month period. Descriptive analyses and regression models were used to determine agreement rates, as well as potential predictors of both agreement and abnormal histology.

RESULTS

Of 390 included colonoscopies, endoscopists (n = 26) reported abnormal gross findings in 218 (56%) and pathologists (n = 4) found histopathology in 195 (50%). Considering histology as the criterion standard, endoscopy had a sensitivity of 90% and a specificity of 78%. Reports of grossly normal endoscopic findings were highly associated with agreement (odds ratio [OR] 1.9, P = 0.001). A known diagnosis of inflammatory bowel disease was a strong predictor of abnormal histology (OR 6.4, P < 0.0001). Abdominal pain as a procedural indication was a strong predictor for normal histology (OR 0.4, P < 0.0001).

CONCLUSIONS

The results of our study suggest good agreement between endoscopic and histological findings, especially when an endoscopist reports normal-appearing colonic mucosa. We identified predictors of abnormal histology to include known inflammatory bowel disease, whereas abdominal pain was found to be a negative predictor. Future studies are needed to determine evidence-based protocols for obtaining biopsies during colonoscopy in children.

Gastrointestinal Endoscopy Competency Assessment Tool: development of a procedure-specific assessment tool for colonoscopy

BACKGROUND

Ensuring competence remains a seminal objective of endoscopy training programs, professional organizations, and accreditation bodies; however, no widely accepted measure of endoscopic competence currently exists.

OBJECTIVE

By using Delphi methodology, we aimed to develop and establish the content validity of the Gastrointestinal Endoscopy Competency Assessment Tool for colonoscopy.

DESIGN

An international panel of endoscopy experts rated potential checklist and global rating items for their importance as indicators of the competence of trainees learning to perform colonoscopy. After each round, responses were analyzed and sent back to the experts for further ratings until consensus was reached.

MAIN OUTCOME MEASUREMENTS

Consensus was defined a priori as ≥80% of experts, in a given round, scoring ≥4 of 5 on all remaining items.

RESULTS

Fifty-five experts agreed to be part of the Delphi panel: 43 gastroenterologists, 10 surgeons, and 2 endoscopy managers. Seventy-three checklist and 34 global rating items were generated through a systematic literature review and survey of committee members. An additional 2 checklist and 4 global rating items were added by Delphi panelists. Five rounds of surveys were completed before consensus was achieved, with response rates ranging from 67% to 100%. Seven global ratings and 19 checklist items reached consensus as good indicators of the competence of clinicians performing colonoscopy.

LIMITATIONS

Further validation required.

CONCLUSION

Delphi methodology allowed for the rigorous development and content validation of a new measure of endoscopic competence, reflective of practice across institutions. Although further evaluation is required, it is a promising step toward the objective assessment of competency for use in colonoscopy training, practice, and research.

Appropriateness, endoscopic findings and contributive yield of pediatric gastrointestinal endoscopy

AIM

To determine the predictability of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and American Society for Gastrointestinal Endoscopy (ASGE) guideline with regard to appropriate endoscopic practice in children, positive endoscopic findings and contributive yield in clinical practice.

METHODS

This was a descriptive, retrospective analysis, conducted at the Department of Paediatrics, University Malaya Medical Centre, Malaysia. All children who had esophagogastroduodenoscopy (EGD) and colonoscopy from January 2008 to June 2011 were included. An endoscopy was considered appropriate when its indication complied with the NASPGHAN and ASGE guideline. All endoscopic findings were classified as either positive (presence of any endoscopic or histologic abnormality) or negative (no or minor abnormality, normal histology); effecting a positive contributive (a change in therapeutic decisions or prognostic consequences) or non-contributive yield (no therapeutic or prognostic consequences).

RESULTS

Overall, 76% of the 345 procedures (231 EGD alone, 26 colonoscopy alone, 44 combined EGD and colonoscopy) performed in 301 children (median age 7.0 years, range 3 months to 18 years) had a positive endoscopic finding. Based on the NASPGHAN and ASGE guideline, 99.7% of the procedures performed were considered as appropriate. The only inappropriate procedure (0.3%) was in a child who had EGD for assessment of the healing of gastric ulcer following therapy in the absence of any symptoms. The overall positive contributive yield for a change in diagnosis and/or management was 44%. The presence of a positive endoscopic finding was more likely to effect a change in the therapeutic plan than an alteration of the initial diagnosis. A total of 20 (5.8%) adverse events were noted, most were minor and none was fatal.

CONCLUSION

The NASPGHAN and ASGE guideline is more likely to predict a positive endoscopic finding but is less sensitive to effect a change in the initial clinical diagnosis or the subsequent therapeutic plan.

An update on pediatric endoscopy

Advances in endoscopy and anesthesia have enabled gastrointestinal endoscopy for children since 1960. Over the past decades, the number of endoscopies has increased rapidly. As specialized teams of pediatric gastroenterologists, pediatric intensive care physicians and pediatric endoscopy nurses are available in many medical centers, safe and effective procedures have been established. Therefore, diagnostic endoscopies in children are routine clinical procedures. The most frequently performed endoscopies are esophagogastroduodenoscopy (EGD), colonoscopy and endoscopic retrograde cholangiopancreaticography (ERCP). Therapeutic interventions include variceal bleeding ligation, foreign body retrieval and percutaneous endoscopic gastrostomy. New advances in pediatric endoscopy have led to more sensitive diagnostics of common pediatric gastrointestinal disorders, such as Crohn's disease, ulcerative colitis and celiac disease; likewise, new diseases, such as eosinophilic esophagitis, have been brought to light.Upcoming modalities, such as capsule endoscopy, double balloon enteroscopy and narrow band imaging, are being established and may contribute to diagnostics in pediatric gastroenterology in the future.

Chronic diarrhoea in children

Chronic diarrhoea in children shows an age related spectrum. In infants and young children a major role is related to persistent intestinal infections, intolerance to specific nutrients such as cow's milk protein, and toddler's diarrhoea. In older children and adolescents, inflammatory bowel diseases are strongly increasing and nonspecific diarrhoea is also frequent. Coeliac disease is a major cause of diarrhoea throughout childhood. In neonates, congenital diarrhoea is a rare but severe syndrome that includes several highly complex diseases. In children, diagnosis should be based on noninvasive techniques. Endoscopy should be decided based on clinical criteria, but also driven by noninvasive tests to assess the digestive absorptive functions and intestinal inflammation. A stepwise approach may reduce the need of endoscopy, also in the light of its relatively limited diagnostic yield compared to adult patients. Treatment of chronic diarrhoea in children is also substantially different from what is generally done in adults and includes a major role for nutritional interventions. Therefore chronic diarrhoea in children is a complex age-specific disorder that requires an age-specific management that is in many aspects distinct from that in adults.

Role of endoscopic ultrasound for evaluating gastrointestinal tract disorders in pediatrics: a tertiary care center experience

BACKGROUND

Endoscopic ultrasound (EUS) with or without fine needle aspiration (FNA) has a well-established role in the evaluation of various gastrointestinal (GI) tract disorders in adults. The clinical impact of EUS on the management of the pediatric population remains less clear. This study evaluates the feasibility, safety, and applications of EUS ± FNA in pediatric GI tract disorders.

PATIENTS AND METHODS

Using a prospectively maintained EUS database, all patients 18 years of age or younger referred for EUS at our institution were identified. Retrospective chart review was conducted to document procedure indications, type of anesthesia used, EUS findings, final FNA cytology results, and clinical impact of EUS ± FNA on the subsequent management of pediatric patients.

RESULTS

Fifty-eight EUS procedures were performed in 56 patients (35 girls). Median age was 16 years (range 4-18 years). The main indications for EUS were acute or recurrent pancreatitis, abdominal pain of suspected pancreatobiliary origin, suspected biliary obstruction, upper GI mucosal/submucosal lesions, and evaluation of pancreatic abnormalities seen on prior imaging. Sedation used included nurse-administered propofol sedation in 38 (73%), general anesthesia in 9 (17%), and fentanyl with meperidine in 3 (6%). Five therapeutic procedures performed included celiac plexus blocks in 4 and 1 EUS-guided pancreatogram. In 44 (86%) patients, EUS provided a new diagnosis. The procedure was successfully completed in all patients with no reported complications.

CONCLUSIONS

EUS ± FNA is feasible and safe and makes a significant impact on most pediatric patients. Nurse-administered propofol sedation appears to be safe and well tolerated in this group.

Small bowel capsule endoscopy in clinical practice: a multicenter 7-year survey

BACKGROUND AND AIM

Data about small bowel capsule endoscopy (SBCE) come from studies involving small and highly selected populations. The study aim was to describe extent of use, indications, results, complications, and practical issues of SBCE in clinical practice in a Northern Italian Region (Lombardia).

MATERIALS AND METHODS

Twenty-three out of 29 invited centers fulfilled a specific questionnaire.

RESULTS

Between 2001 and 2008, 2921 procedures were performed and both the number of centers performing SBCE (from 5 to 29) and the number of SBCE (from 7.2 to 69.2 per month) increased steadily. The main indications for SBCE were: obscure gastrointestinal bleeding (OGIB) (43.4%), unexplained anemia (23.9%), suspected Crohn's disease (7.8%) and abdominal pain (5.3%). Overall, SBCE was positive in 50% of cases, negative in 36% and undefined in 14%. The highest diagnostic yields were observed in patients with OGIB (62.5%), polypoid syndromes (74.1%), known (54.8%) or suspected (47.3%) inflammatory bowel disease, while the yields were low in patients examined for chronic diarrhea (27.4%) and abdominal pain (14.9%), 61 patients (2.1%) experienced capsule retention. Thirty-two of them eventually excreted the capsule naturally while endoscopic or surgical retrieval was necessary in 29 (1%) (in two because of obstruction).

CONCLUSION

Over a period of 7 years the use of SBCE in Lombardia increased steadily confirming, in clinical practice, a high diagnostic yield and an acceptable safety profile.

General considerations and updates in pediatric gastrointestinal diagnostic endoscopy

Gastrointestinal and colonic endoscopic examinations have been performed in pediatric patients in Korea for 3 decades. Endoscopic procedures are complex and may be unsafe if special concerns are not considered. Many things have to be kept in mind before, during, and after the procedure. Gastrointestinal endoscopy is one of the most frequently performed procedure in children nowadays, Since the dimension size of the endoscopy was modified for pediatric patients 15 years ago, endoscopic procedures are almost performed routinely in pediatric gastrointestinal patients. The smaller size of the scope let the physicians approach the diagnostic and therapeutic endoscopic procedures. But this is an invasive procedure, so the procedure itself may provoke an emergence state. The procedure-related complications can more easily occur in pediatric patients. Sedation-related or procedure-related respiratory, cardiovascular complications are mostly important and critical in the care. The endoscopists are required to consider diverse aspects of the procedure - patient preparation, indications and contraindications, infection controls, sedation methods, sedative medicines and the side effects of each medicine, monitoring during and after the procedure, and complications related with the procedure and medicines - to perform the procedure successfully and safely. This article presents some important guidelines and recommendations for gastrointestinal endoscopy through literature review.

A long-term follow-up study on endoscopic management of children and adolescents with chronic pancreatitis

OBJECTIVES

Data on therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for chronic pancreatitis (CP) in children and adolescents, especially with long-term follow-up of consequences, are rarely reported. The aim of this study was to determine the long-term follow-up results of therapeutic ERCP for CP in children and adolescents.

METHODS

All patients with CP who received therapeutic ERCP at Changhai Hospital from January 1997 to May 2009, with the age at first onset of pain being less than 18.0 years, were included. Attempts were made to contact all adolescents and follow-up data were recorded. Clinical data were assessed before and after every ERCP.

RESULTS

Follow-up information was available in 42 (91.3%) of the 46 patients who received therapeutic ERCP. There were 20 boys and 22 girls, with the age at first onset being 11.8+/-4.5 years. A total of 110 therapeutic ERCP sessions were performed in the 42 patients. The post-ERCP complication rate was 17.3%, including mild and moderate pancreatitis (n=17) and mild cholangitis (n=2). The mean follow-up period of time was 61.4 (range: 24-132) months. Five patients underwent subsequent surgery because of refractory abdominal pain after endotherapy. Of the remaining 37 patients who received therapeutic ERCP alone, abdominal pain improved in 30 (81.1%) patients, and was completely relieved in 24 (64.9%) patients during the period of follow-up.

CONCLUSIONS

Therapeutic ERCP may offer long-term improvement in pain in children and adolescents with CP.

Impact of the Rome II paediatric criteria on the appropriateness of the upper and lower gastrointestinal endoscopy in children

BACKGROUND

The demand for paediatric gastrointestinal (GI) endoscopy has increased, resulting in a significant rise of overall costs.

AIM

To assess the clinical impact of the Rome II criteria for functional gastrointestinal disorders when selecting paediatric patients who underwent GI endoscopy.

METHODS

The indications and findings of GI endoscopic procedures performed before and after the publication of the Rome II criteria were evaluated retrospectively.

RESULTS

Upper GI endoscopy was performed in 1124 children, whereas colonoscopy was performed in 500 subjects. A total of 607 (54%) oesophago-gastro-duodenoscopies (OGDs) were positive and 517 (46%) were negative, whereas 306 (61.1%) colonoscopies were positive and 194 (38.9%) were negative. Of the 1624 procedures, 26% were considered inappropriate according to the Rome II criteria. Inappropriate procedures decreased significantly after publication of the Rome II criteria (OR, 3.7; 95% CI, 1.8-7.5). Of 1202 appropriate GI endoscopies, 502 OGD (62.7%) were significantly contributive, compared with only 105 (32.5%) of the 323 inappropriate procedures (OR, 3.5; 95% CI, 2.6-4.6), whereas 265 (65.8%) colonoscopies were significantly contributive, compared with only 41 (42.3%) of the 97 inappropriate procedures (OR, 2.6; 95% CI, 1.6-4.1).

CONCLUSIONS

The use of the criteria for functional gastrointestinal disorders makes a significant positive impact, they should reduce unnecessary paediatric GI endoscopy.

EUS in pediatric patients

BACKGROUND

The knowledge of EUS use in children is limited.

OBJECTIVE

We investigated the indications, feasibility, safety, and clinical utility of EUS in the management of pediatric GI, pancreatobiliary, and mediastinal diseases.

DESIGN

Retrospective study.

SETTING

Two tertiary referral university hospitals.

PATIENTS

Consecutive children age younger than 18 years referred over a 7-year period for EUS evaluation.

RESULTS

Forty EUS scans were performed in 38 children with a mean age of 13.5 years. The indications for pancreatobiliary endosonography were pancreatitis (n = 10), solid pancreatic mass (n = 7), cystic pancreatic mass (n = 1), cyst in the setting of chronic pancreatitis (n = 1), suspected annular pancreas (n = 1), celiac plexus block (n = 1), suspected common bile duct stone (n = 1), abdominal pain and atrophic pancreas (n = 1), ampullary adenoma (n = 1), and abnormal MRCP in a patient with jaundice (n = 1). The indications for gastric EUS were mucosal lesions (n = 2) and subepithelial lesions (n = 4). The indications for mediastinal endosonography were mediastinal masses/lymph nodes (n = 5). The remaining evaluations were performed for esophageal stricture (n = 1), unexplained abdominal pain (n = 1), unexplained abdominal pain with celiac axis block (n = 1), and perirectal fluid collection (n = 1). EUS-guided FNA (EUS-FNA) was performed in 12 (30%) cases and established the correct diagnosis in 9 (75%). EUS-guided fine-needle injections for celiac axis block were performed in 2 (5%) cases. The procedure was successful in all patients, and no complications related to sedation, EUS, or EUS-FNA were encountered.

LIMITATION

Retrospective study.

CONCLUSION

EUS and EUS-FNA are feasible and safe and have a significant impact on the management of pediatric GI, pancreatobiliary, and mediastinal diseases.

Repeat endoscopy affects patient management in pediatric inflammatory bowel disease

OBJECTIVES

Endoscopy is commonly performed in the diagnosis of children with inflammatory bowel disease (IBD). The utility of repeat endoscopy for the management of pediatric IBD has not been subject to investigation. The frequency and determinants of changes in medical management resulting from endoscopy are unknown.

METHODS

We conducted a cross-sectional cohort study to assess the frequency and determinants of management change in all children (0-21 years) who underwent endoscopy for the surveillance or evaluation of established IBD between July 2002 and July 2006 at 2 referral centers in the United States. Patients were sampled from the Pediatric Endoscopy Database System Clinical Outcomes Research Initiative and a chart review was performed to identify demographic features (age, gender), blood work (hemoglobin, albumin, erythrocyte sedimentation rate, C-reactive protein), and endoscopy results (endoscopic and histologic). An endoscopic score was used to assess mucosal injury. Subjects were divided into two groups for comparative analysis: (i) patients with management changes based on endoscopic or histologic findings, and (ii) patients without changes.

RESULTS

We analyzed 285 endoscopic procedures (137 colonoscopies, 109 esophagogastroduodenoscopy (EGD) with colonoscopy, 25 sigmoidoscopies, 8 EGDs, 6 EGDs with sigmoidoscopy) performed in 230 children (mean age 14.5) with established IBD, including 147 with Crohn's disease, 80 with ulcerative colitis, and 3 with indeterminant colitis. Management changes were documented in 119 (42%) procedures, including 58 (20%) immediately after endoscopy, 52 (18%) after histology review, and 9 (3%) after both. Management changes included new medications in 86 cases, discontinuation of a medication in 3 cases, hospital admission in 11, and surgical consult in 14. No significant differences between groups occurred with regard to age, gender, endoscopy type, or infliximab use. The presence of anemia, hypoalbuminemia, or elevated markers of inflammation (ESR, CRP) did not correlate with management outcome. Management changes after endoscopy were more frequent in patients with Crohn's disease as compared to patients with ulcerative colitis. Patients with mucosal injury were more likely to have a management change than those with mucosal healing (80% vs. 20%; P<0.001).

CONCLUSIONS

The overall rate of management change after endoscopic evaluation in children with IBD is approximately 42%. Addition of a new medication is the most common intervention. Blood work and patient symptoms before the procedure did not predict management outcome; however, mucosal healing may be an important end point. Our findings suggest that endoscopy is valuable for the evaluation of children with IBD.

[Endoscopic retrograde cholangiopancreatography in patients aged less than 18 years old: our experience]

BACKGROUND

There is scant information on the use of endoscopic retrograde cholangiopancreatography (ERCP) in patients under 18.

OBJECTIVE

To analyze our experience in all patients under 18 who underwent ERCP.

PATIENTS AND METHODS

We performed a retrospective study of all ERCP conducted in patients under 18 between 1993 and 2006. We analyzed indications, endoscopic and radiologic findings, diagnostic and therapeutic success, and complications.

RESULTS

We included 31 patients who underwent 36 ERCP in total. The mean age was 9.89 +/- 5 years old. We used general anesthesia in 58.3% (21 patients), with a mean age of 8 +/- 5 years. The most frequent indications were complications after liver transplantation in 33.3% (12 patients), suspicion of biliary obstruction in 27.7% (10 patients), and pancreatitis in 22.2% (8 patients). We achieved cannulation and repletion in the selected duct in 94.4%. The most frequent pathologic findings were changes in the biliary tract after liver transplantation in 25% (9 patients). The results of ERCP were normal in 10 patients (27.7%). Therapeutic maneuvers were indicated in 17 out of the 34 (50%) examinations considered, achieving therapeutic success in 76.47% (13/17). Complications consisted of hemorrhage after simple sphincterotomy in one patient (2.8%) and mild pancreatitis in two patients (5.6%).

CONCLUSIONS

We found ERCP to be a safe procedure with a high diagnostic and therapeutic success rate, and a low rate of early complications.
