Variation in Preoperative Testing and Antireflux Surgery in Infants

A Multidisciplinary Approach to Infants With GERD-Like Symptoms: A New Paradigm

OBJECTIVES

Infants with gastroesophageal reflux disease (GERD)-like symptoms have been classically defined as having a wide array of symptoms. In these instances, anti-reflux medications are ineffective and overprescribed. Rather these symptoms are more attributable to dysphagia and unsettledness/colic. To address these conditions at our center, both speech language pathologist (SLP) and/or occupational therapist (OT) have contributed to evaluation. We hypothesized that dysphagia and unsettledness/colic are highly prevalent, yet under recognized in this population.

METHODS

Full-term infants with typical development and under 6 months of age (N = 174) were included. Infants with suspected dysphagia and/or evident colic/unsettledness were evaluated by SLP and OT, respectively.

RESULTS

GERD-like symptoms were present in 109 infants with attributes of dysphagia in n = 46, unsettledness/colic in n = 37, and combined in n = 26.

CONCLUSION

A multidisciplinary approach, including SLP and OT, is recommended for the evaluation of infants with GERD-like symptoms.

Anti-reflux surgery in neonates and infants: analysis of indications, outcomes, and link to mortality among primary and secondary gastroesophageal reflux patients

Background

The indications and benefits of anti-reflux surgery (ARS) in neonates and infants are uncertain. Prematurity, operation before 1 year of age, neurological impairment (NI), and chronic lung disease (CLD) are risk factors for surgical failure. We aim to document the indications, management, and outcomes of ARS in this age group and compare them among primary and secondary gastroesophageal reflux (GERD).

Results

Between January 2008 and December 2019, 24 males and 22 females had ARS; 13 (28.3%) for primary while 33 (71.7%) for secondary GERD. The mean gestational age was 34.6 weeks (range 24–41) and mean birth weight was 2000 gm (range 600–3300). The weight at time of referral ranged from 1.4 kg to 4 kg (mean 2.2 kg). There were no significant differences between the two groups regarding the previous data. The group of primary GERD presented mainly with recurrent aspiration (n = 8), recurrent apnea (n = 5), and recurrent desaturations with or shortly after feeds (n = 4). The group of secondary GERD were referred for poor sucking with failure to thrive (FTT) (n = 25), recurrent aspiration (n = 20), and gastrostomy request (n = 14). The risk factors for secondary GERD were neurologically impaired (n = 22), post-esophageal atresia (EA) repair (n = 9), hiatus hernia (n = 4), thoracic stomach (n = 2), N-type tracheoesophageal fistula (TEF, n = 4), and congenital esophageal stenosis (CES, n = 4). The operations included open Nissen’s fundoplication (ONF) (n = 4) and modified open Thal’s fundoplication (MOTF) (n = 42). There were 8 mortalities in the secondary group, unrelated to surgery. Morbidities after Nissen’s fundoplication included wrap migration, gas bloat, and reoperation in one, laparotomy for intestinal obstruction (IO) in one. Following MOTF, there were two cases of transient recurrent GERD which improved with time and laparotomy in one for IO.

Conclusions

Diagnostic tests remain a challenge. Isolated TEF and CES may require fundoplication for staged management. Cases of the primary group did better with MTFO. Prematurity, CLD and age < 2 months were not significant risk factors for fundoplication failure or mortality. Neurological impairment was a risk factor for mortality.

Outcomes of laparoscopic nissen fundoplications in children younger than 2-years: single institution experience

BACKGROUND

Variation exists in the diagnostic testing for gastroesophageal reflux (GER) in infants and in the application of surgical therapy. There has been an increase in antireflux surgery (ARS) since the development of laparoscopy but the outcomes in high-risk infants is unclear. This study examines the results of laparoscopic fundoplication in infants less than 2 years.

METHODS

The results of infants less than 2 years undergoing laparoscopic Nissen fundoplication (Lap-F) from 2012 to 2015 were retrospectively reviewed and outcomes were followed until 2017.

RESULTS

There were 106 patients, median gestational age 32.50 weeks ± 6.35 SD and non-corrected age at operation 23.0 weeks ± 19.0 SD, mean weight of 4.81 kg ± 2.10 SD. One of the most common reasons for surgical consultation was improvement in respiratory status after insertion of nasoduodenal feeding tube. Of the Lap-F, 100 were with gastrostomy tube (GT). There were no conversions to open or intraoperative complications. The complication rate was 4.71%, and the reoperation rate was 5.66%, one fundoplication revision and the others gastrostomy revisions. The median time for feeds and to reach goal were 1 (1-14) and 4 (2-279) days, respectively. The 30-day mortality was 0.9% and long-term it was 4.71%. The long-term mortality was related to the underlying medical problems. The median follow-up was 113 (3-286) weeks. One patient required revision of the fundoplication and none required esophageal dilatation during the follow-up period.

CONCLUSION

Fundoplication is effective for relief of symptoms of GER in children younger than 2 years. The procedure has a low morbidity and mortality in this population.

Acid suppressants for managing gastro-oesophageal reflux and gastro-oesophageal reflux disease in infants: a national survey

OBJECTIVES

To evaluate the diagnosis and management of reflux and gastro-oesophageal reflux disease (GORD) in infants aged <1 year presenting to general practitioners (GPs).

DESIGN, SETTING AND PARTICIPANTS

A nationally representative, prospective, cross-sectional survey of GP activity in Australia, 2006-2016 (Bettering the Evaluation And Care of Health Study). Annually, a random sample of around 1000 GPs recorded details for 100 consecutive visits with consenting, unidentified patients.

OUTCOME MEASURES

Diagnoses of reflux and GORD and their management including prescribing of acid-suppressant medicines (proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs)) and counselling, advice or education.

RESULTS

Of all infants' visits, 512 (2.7%) included a diagnosis of reflux (n=413, 2.2%) or GORD (n=99, 0.5%). From 2006 to 2016, diagnostic rates decreased for reflux and increased for GORD. Prescribing of acid suppressants occurred in 43.6% visits for reflux and 48.5% visits for GORD, similar to rates of counselling, advice or education (reflux: 38.5%, GORD: 43.4% of visits). Prescribing of PPIs increased (statistically significant only for visits for reflux), while prescribing of H2RAs decreased.

CONCLUSIONS

Overprescribing of acid suppressants to infants may be occurring. In infants, acid-suppressant medicines are no better than placebo and may have significant negative side effects; however, guidelines are inconsistent. Clear, concise and consistent guidance is needed. GPs and parents need to understand what is normal and limitations of medical therapy. We need a greater understanding of the influences on GP prescribing practices, of parents' knowledge and attitudes and of the pressures on parents of infants with these conditions.
