Complications after transesophageal echocardiogram in pediatric patients with gastrostomy tube and/or Nissen fundoplication.

Abstract

INTRODUCTION\nTransesophageal echocardiography (TEE) is frequently used in children with and without congenital heart disease when transthoracic echocardiography is inadequate for visualizing cardiac structures. Recent guidelines state relative contraindications of TEE include post-gastrostomy tube (GT) or Nissen fundoplication surgery. No data exist documenting the incidence of complications in this population after a TEE. Aim of this study was to document the incidence of abdominal complications after TEE in pediatric patients who previously had a GT or Nissen fundoplication.\n\n\nMETHODS\nSingle institution retrospective study was performed evaluating patients from 2013 through 2020. Patients were included if they had previously undergone a GT or Nissen procedure and subsequently underwent a TEE procedure. Baseline demographics were obtained. Major (esophageal/gastric perforation, oropharyngeal dysphagia, GT displacement, and Nissen breakdown) and minor (abdominal pain, feeding intolerance, and GT leakage) complications were recorded.\n\n\nRESULTS\nTotal of 34 patients underwent 48 TEE procedures. Age was 6.2\xa0±\xa06.6 years (median 3.0 years, .4 - 23.0 years) and weight was 18.5\xa0±\xa014.8 kgs (median 12.4 kgs, 4.2 - 57.5\xa0kg) at time of TEE. Twenty-nine patients had congenital heart disease. Five patients had a Nissen fundoplication, 14 patients had a GT, and 15 patients had both procedures prior to the TEE. No patient had a major abdominal complication after the TEE. One patient had abdominal pain (2.1%), one patient had feeding intolerance and leakage around the GT site (2.1%), and two patients had leakage around the GT site (4.2%) after the TEE. Patients that experienced complications were significantly younger (1.7\xa0±\xa01.1 years vs. 6.6\xa0±\xa06.7 years, P\xa0<\xa0.01) and weighed less (8.7\xa0±\xa03.5\xa0kg vs. 20.1\xa0±\xa015.5\xa0kg, P\xa0<\xa0.01) than those that had no complications. All minor complications resolved with minimal interventions required.\n\n\nCONCLUSION\nIn this study, major abdominal complications did not occur after a TEE procedure in pediatric patients that had previous abdominal surgeries. The incidence of minor complications was relatively low and was easily remedied in this patient population. Though a relative contraindication by guidelines, TEE imaging, including transgastric views, can be performed relatively safely in pediatric patients with prior abdominal surgeries if needed.
