Jejunal Feeding Via Gastrojejunal Tube in Refractory Gastroesophageal Reflux

Gastroesophageal reflux disease (GERD) in children can be severe and lead to multiple complications, among them dizziness, esophagitis, respiratory failure or ENT infections. In the case of resistance o proton pump inhibitors (PPIs) therapy, alternatives treatments includes anti-reflux surgery or fasting associated with parenteral nutrition.

The use of gastrointestinal tubes (GJT) is relatively recent. Its objective is to allow a direct jejunal feeding, thus limiting the risk of severe gastroesophageal reflux disease (GERD).

Jejunal feeding using GJT has been compared to surgical techniques without finding any superiority.

However, the risk of GERD recurrence appears to be greater if anti-reflux surgery is performed at a young age.

As an alternative to anti-reflux surgery, prolonged parenteral nutrition (PN) is burdened with its own morbidity (metabolic, infectious, vascular).

In addition, the natural course of GERD is usually towards spontaneous improvement with the age and growth of the child. GJT may be used to postpone anti-reflux surgery and prevent PN while waiting for spontaneous GERD improvement.

Literature data found in a cohort of 27 children, 5 did not require surgery or parenteral nutrition after placement of GJT. However, this study is difficult to analyze because of 9/27 deaths.

Complications from GJT are common, ranging from obstruction of the tube requiring replacement to jejunal perforation that is a life treating condition.

This monocentric, retrospective study will be conducted at a French pediatric university hospital. The study was approved by hospital's ethics committee and aims to help to evaluate the potential advantages of GJT feeding in hospital settings among patients admitted with severe GERD and determine if this feeding route may prevent or postpone recourse to invasive procedures like surgery or alternative nonsurgical treatments like parenteral nutrition (PN) that have morbidity in order to control the reflux disease and its complications and at the same time prevent growth deficit among affected children.

The data will be entered on an e-CRF (Epidata) from the patient files consulted on site by the investigators or a person delegated by them. The data will be anonymized when entered with only the order number, initials and year of birth of the patients. The correspondence table will be kept in each participating center by the local investigator. Only professionals involved in this study will have access to the pseudonymised database. Data will be recorded on a restricted access server. Persons with direct access to the data take all necessary precautions to ensure the confidentiality of this data. The anonymized data will be stored on secure servers not connected to the Internet.

The quantitative variables will be described in mean and standard deviation. Qualitative variables will be described in numbers (percent). Comparison tests. Qualitative data will be analyzed with Chi2 or Fischer's exact test. The qualitative values will be analyzed using Student's t-test if their distribution is normal or by the non-parametric Mann-Whitney test. Multivariate analysis will use logistic regression to study age, weight and initial pathology. The significance threshold was set at p \< 0.05

The primary outcomes are :

Need for invasive GERD treatments, anti-reflux surgery or parenteral nutrition 1 month after Gastrojejunal tube placement and at the end of follow-up.

Secondary outcomes are:

Duration of use of Gastrojejunal tube. type of the Gastrojejunal tube

The following criteria will be compared before and after the installation of Gastrojejunal tube :

• Anti-reflux treatments
• Complications of GERD: respiratory, dizziness
• Duration of hospitalization
• Intussusception, Dumping syndrome,
• Mechanical complications: obstruction, extrajejunal displacement, extraction, rupture of the GJT
• Weight and height

No intervention

Plazo: 4 months
