General considerations and updates in pediatric gastrointestinal diagnostic endoscopy

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.

Use of Hypnosis in Paediatric Gastrointestinal Endoscopy: A Pilot Study

Objectives: Experience of hypnosis in gastrointestinal (GI) endoscopy is scarce in children. Our aims were to assess the rate of successful GI endoscopy performed using hypnosis alone or in combination with midazolam, with or without additional equimolar mixture of oxygen and nitrous oxide (EMONO), and to identify predictive factors of successful endoscopy in children. Methods: This prospective single-centre study included children older than 6 years requiring a diagnostic esophagogastroduodenoscopy (EGD) or rectosigmoidoscopy. Ericksonian hypnosis was performed alone or in combination with midazolam, with or without additional EMONO. Successful endoscopy was defined by a complete and well-tolerated procedure. Levels of satisfaction of the endoscopist, nurse, and patient were assessed. Results: One hundred forty children [70 boys, median age: 12 years (Q1-Q3: 9-14)] were included over a 14-month period. They underwent EGD in 51.4% (n = 72) and rectosigmoidoscopy in 48.6% (n = 68) of cases. EMONO and midazolam were combined with hypnosis in 136 cases (97.1%). Successful endoscopy rate reached 82.9%. The procedure was interrupted due to poor tolerance and was rescheduled under general anaesthesia in 11 patients (7.9%). Predictive factors for successful endoscopy were older age (13 vs. 8 years, OR: 1.34, CI 95% [1.10-1.62], p = 0.003) and type of endoscopy (EGD vs. rectosigmoidoscopy, OR: 16.34 [2.14-124.68], p = 0.007). A good cooperation of the patient was reported by the endoscopist and the nurse in 88.4 and 86.9% of cases, respectively. Ninety-two per cent of patients mentioned that the procedure went well. Conclusions: Our study suggests that hypnosis combined with EMONO and/or midazolam is of additional value to perform diagnostic EGD or rectosigmoidoscopy in children older than 6 years without systematic need for general anaesthesia.

Dexamethasone Reduces Postoperative Nausea in Pediatric Upper Endoscopy With Deep Sedation: A Randomized Controlled Trial

OBJECTIVES

We aimed to evaluate the effect of a single dose of preoperative dexamethasone on postoperative nausea and vomiting (PONV), a frequent complication and a major cause of delayed recovery in pediatric upper gastrointestinal endoscopy (UGIE) under sedation.

METHODS

In this double-blind randomized controlled study, 98 children aged 2 to 14, with American Society of Anesthesiologists status I to II, and undergoing elective UGIE with deep sedation were included and randomly assigned to 2 groups. Preoperatively, after anesthesia induction with sodium thiopental and maintenance with sevoflurane, patients in the intervention (n = 49) and control (n = 49) groups, respectively received 0.1 mg/kg i.v. dexamethasone and 2 cm i.v. 0.9% saline. Postoperatively, PONV incidence was measured as the primary outcome.

RESULTS

PONV incidence was significantly less in dexamethasone group (8.2%) compared to the control group (26.5%) (difference = 18.3%, 95% confidence interval: 3.4%-33%, P = 0.016). For secondary outcomes, between-group differences were not statistically significant: incidence of bronchospasm or laryngospasm (both 4.1%, P = 1); emergence delirium assessed with Pediatric Anesthesia Emergence Delirium scale (5.9 ± 3.4 vs 5.7 ± 3.2, P = 0.751); Modified Aldrete score at 0 minutes (9.4 ± 0.8 vs 9.3 ± 0.9, P = 0.909) and at 5 minutes (9.5 ± 0.7 vs 9.4 ± 0.9, P = 0.527); and recovery time (21.1 ± 6.6 vs 23.4 ± 8.6 minutes, P = 0.130).

CONCLUSIONS

A single preoperative dose of i.v. dexamethasone reduces PONV in children undergoing elective UGIE with deep sedation, but has no significant effect on the patient recovery time or the incidence of postoperative bronchospasm or laryngospasm and emergence delirium.

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.
