Gastroesophageal reflux strictures in children, management and outcome

Laparoscopic Approach of the Obstruction of the Lower Third of the Esophagus in Children

Objective: To review the diagnostic methodology in pediatric patients with obstruction of the lower third of the esophagus as well as minimally invasive therapeutic options. Materials and Methods: Retrospective study carried out reviewing records of children with esophageal obstruction diagnostic, from 2000 to 2018. They were divided into Group I stenosis secondary to reflux; Group II achalasia; and Group III embryonic remnants. Results: Thirty-three patients. Group I: 7; esophageal barium swallow irregular stenosis of the distal third and endoscopy irregular stenosis in 7. Treated with laparoscopic fundoplication 2, Collis Nissen 5. Group II: 22 patients, age X = 11.55 years. All with dysphagia and symmetrical stenosis of esophagogastric junction. Fifteen underwent manometry and all underwent intraoperative endoscopy. All had laparoscopic myotomy, with 2 perforations and no conversions, 2 patients had subsequent dysphagia to solids, and they did not need esophageal dilatation. Group III: 4 patients, stenosis was above esophagogastric junction. On endoscopy, inflammation was present in all 3 with irregular esophagogastric junction and difficulty passing endoscope. Three patients underwent laparoscopic resection and anastomosis. One patient leaked and developed a fistula. One patient has not been operated upon as yet. Conclusions: In those patients, the best surgical option depends upon the diagnosis. Esophageal barium studies and endoscopy allow discerning among them.

Predictors of multiple readmissions or death in the first year after Nissen fundoplication in children

PURPOSE

Nissen fundoplication (NF) is commonly performed in children with gastro-esophageal reflux disease (GERD). Patients undergoing NF often have co-morbidities. Reported outcomes of NF vary considerably. This study investigated which factors might predict multiple readmissions or death in the first year following NF at our institution.

METHODS

A retrospective chart review of 187 children who underwent NF at our institution between January 2004 and December 2015 was undertaken. Underlying medical conditions, age, weight, presence of malnutrition, length of hospital stay prior to surgery and type of surgery were recorded. Patients who had more than one admission in the first post-operative year were compared to those who had one or none, and patients who died within the first post-operative year were compared to those who did not.

RESULTS

Risk factors for multiple readmissions were underlying cardiac disease (p = 0.011), esophageal atresia (EA) (p = 0.011), and esophageal stricture (p = 0.0002). Risk factors for death included younger age (p = 0.028), need for gastrostomy tube (GT) (p = 0.01) and prolonged pre-operative hospital admission (p = 0.0003).

CONCLUSION

This study identified multiple factors associated with readmission and death in the first year after NF. These findings will help with the counseling patients and caregivers regarding expectations following NF.

Efficacy and safety of endoscopic dilatation in the management of esophageal strictures in children

Objectives:

To determine the outcomes of endoscopic dilatation of esophageal strictures in children.

Methods:

Children younger than 18 years of age diagnosed with esophageal strictures over a period of 7 years (June 2010 to June 2017) were reviewed and analyzed retrospectively. The study took place at King Khalid University Hospital, Riyadh, Saudi Arabia. The patients’ clinical characteristics, endoscopic findings, and details of the strictures, treatment, and outcomes were documented.

Results:

Forty-three children with esophageal strictures were identified (median age, 8.1 years; range, 2-17 years; 23 [53.5%] boys). The median age at presentation was 2 years (range, 1-16 years), and the median follow-up period was 3 years (range, one month-17 years). Tracheoesophageal fistula (n=14, 32.6%), gastroesophageal reflux disease (n=10, 23.3%) and eosinophilic esophagitis (n=8, 18.6%) were the leading causes of esophageal strictures. Forty-three patients underwent 180 dilatation sessions; the median number of dilatation sessions per patient was 3 (range, 1-48), and the median interval between sessions was 8 weeks (range, 1-24 weeks). Among 180 dilatation sessions, 3 events (1.7%) of esophageal perforation were observed. The outcomes varied depending on the primary cause of the stricture; complete response was achieved the best in eosinophilic esophagitis-related strictures (87.5%), followed by anastomotic strictures post tracheoesophageal fistula repair (71.4%) and gastroesophageal reflux disease-related strictures (70%).

Conclusion:

Endoscopic dilatation is a safe and effective intervention in the management of esophageal strictures in children, with minimal complications when conducted by experts.

Esophageal replacement

This article focuses on esophageal replacement as a surgical option for pediatric patients with end-stage esophageal disease. While it is obvious that the patient׳s own esophagus is the best esophagus, persisting with attempts to retain a native esophagus with no function and at all costs are futile and usually detrimental to the overall well-being of the child. In such cases, the esophagus should be abandoned, and the appropriate esophageal replacement is chosen for definitive reconstruction. We review the various types of conduits used for esophageal replacement and discuss the unique advantages and disadvantages that are relevant for clinical decision-making.

Indwelling esophageal balloon catheter for benign esophageal stenosis in infants and children

BACKGROUND

Balloon dilatation of benign esophageal strictures is an established mode of therapy in adults and children. There remains a group of patients with refractory stenosis despite dilatation at regular intervals. An indwelling balloon catheter may offer an alternative.

METHODS

This is a retrospective study of 19 children who underwent esophagoscopy between 2004 and 2012 with placement of an indwelling balloon catheter for refractory esophageal stenosis. Total number of endoscopies, number of endoscopies with indwelling balloon catheter, as well as complications, reoperations, and mortality due to use of the balloon catheter were studied.

RESULTS

Patient age ranged from 4 weeks to 15 years. The indwelling balloon catheter was used to treat refractory stenosis after corrective surgery of long gap esophageal atresia (n = 5), esophageal atresia with distal fistula (n = 2), refractory esophageal stenosis due to caustic esophageal burns (n = 7), reflux (n = 2), and stenosis of unknown cause (n = 3). With the indwelling balloon catheter in place, the mean number of endoscopies equalled four. Complications were restenosis after a symptom-free period for which a new indwelling balloon catheter was necessary (n = 3). Two others needed two to five additional dilations: balloon leakage requiring replacement (n = 7 in 5 patients), sputum retention (n = 1), and dislodgement (n = 5 in 4 patients). More importantly, there was no mortality or the need for any patient to undergo a surgical resection.

CONCLUSIONS

The indwelling balloon catheter is safe to use and can be used by parents at home. More importantly it obviates the need for rethoracotomy/-scopy or esophageal replacement.

Consumo alimentar de crianças e adolescentes com disfagia decorrente de estenose de esôfago: avaliação com base na pirâmide alimentar brasileira

OBJETIVO: Avaliar o consumo alimentar de pacientes com disfagia decorrente de estenose de esôfago, comparando a dieta de consistência líquida com a dieta de consistência pastosa e sólida, com base na Pirâmide Alimentar Brasileira. MÉTODOS: Estudo de corte transversal, no qual foram incluídos consecutivamente 31 pacientes com estenose esofágica, sendo 18 (58,0%) cáustica, 7 (22,6%) pós-cirúrgica, 3 (9,7%) péptica e 3 (9,7%) sem causa definida. Empregou-se o recordatório de 24 horas; os alimentos foram transformados em porções em função dos oito grupos de alimentos, conforme recomendado por Philippi. Utilizou-se o teste Kruskal-Wallis e Exato de Fisher, fixando em 5% o nível de rejeição da hipótese de nulidade. RESULTADOS: A idade variou entre 15 e 176 meses (mediana, 56 meses), sendo 28 crianças e três adolescentes, e 18 do sexo masculino. Vinte e nove pacientes (93,5%) apresentavam disfagia, sendo grave em 34,4% (10/29), moderada em 41,3% (12/29), e leve em 24,1% (7/29). O consumo mediano de porções de cereais, leguminosas, e óleos e gorduras foi menor no grupo com dieta líquida (p<0,005), o qual também apresentou maior proporção de pacientes cujo consumo foi abaixo do proposto pela pirâmide alimentar quando comparado ao grupo com dieta pastosa e sólida, com diferença estatisticamente significante (p<0,05). CONCLUSÃO: O suporte nutricional é de extrema importância no tratamento de pacientes com estenose esofágica, principalmente na disfagia grave, cuja dieta deve ser adaptada à consistência líquida, devido ao risco nutricional que se atribui à limitada ingestão alimentar, e para que o tratamento dietético seja precocemente instituído.

Gastrointestinal intervention in children

Interventional radiology is a rapidly growing discipline in paediatrics. Many non-vascular interventional techniques may be used in the gastrointestinal tract in children. The technically simpler and more common of these may be adopted by any paediatric radiologist with an interest in interventional radiology. Other rarer and more complex techniques are currently restricted to specialist centres with a higher overall caseload. This review emphasizes the common procedures such as oesophageal dilatation, gastrostomy, insertion of transgastric jejunal feeding tubes and biopsy. Less common salivary, hepatobiliary, pancreatic and intestinal interventions are also described.

Reflux esophageal stricture--a review of 30 years' experience in children

PURPOSE

Strictures of the esophagus in children may have multiple etiologies including congenital, inflammatory, infectious, caustic ingestion, and gastroesophageal reflux (peptic stricture [PS]). Current literature lacks good data documenting long-term outcomes in children. This makes it difficult to counsel some patients about realistic treatment expectations. The objective of this study is to evaluate our institutional experience and define the natural history and treatment outcomes.

METHODS

A retrospective review of clinical data obtained from children who underwent dilation for PS was performed.

RESULTS

Over the past 30 years, 114 children and adolescents received 486 dilations. The most common indications for stricture dilation were PS (42%) and esophageal atresia (38%). Other lesser indications included congenital, foreign body, corrosive, cancer, radiation, allergic, and infectious. This review focuses on the 48 children with PS. Of the children with PS, a congenital anomaly was identified in 23 children; and 12 had neurologic impairment. Average age at presentation was 10.2 years (range, 0.5-18.3 years). Most patients had had symptoms for many months before diagnosis. Peptic stricture was most common in the lower esophagus (n = 39). However, middle (n = 8) and upper (n = 1) strictures were occasionally identified. Noncompliance with medical therapy was a challenge in 12% (n = 5) of children. Children with a PS received a median of 3 dilations, but a subset of 5 patients with severe strictures underwent up to 48 dilations (range, 1-48). Repeated dilations were required for a median of 20 months (range, 1-242 months). Among patients receiving esophageal dilation for PS, 94% required an antireflux procedure (19% required a second antireflux surgery). A subgroup of patients (n = 10) was identified who required extended dilations, multiple surgeries, and esophageal resection. This subgroup had a significantly longer period of symptomatic disease and increased risk of esophageal resection compared with those patients requiring fewer dilations. Surgical resection of the esophageal stricture was ultimately required in 3 children with PS after failure of more conservative measures.

CONCLUSION

Children and adolescents presenting with reflux esophageal stricture (PS) frequently require antireflux surgery, redo antireflux surgery, and multiple dilations for recurrent symptoms. We hope that these data will be of use to the clinician attempting to counsel patients and parents about treatment expectations in this challenging patient population.

Esophegeal replacement in children with AIDS

We report 2 human immunodeficiency virus-positive patients with refractory esophageal strictures secondary to candidiasis. They presented with progressive dysphagia and had suffered from oropharyngeal and/or esophageal candidiasis within the preceding 3 months. Both failed conservative management of these strictures, including systemic antifungal therapy, administration of proton pump inhibitors, and numerous attempts at stricture dilation, ultimately progressing to open transhiatal esophagectomy. Although challenging in the immunocompromised host, successful treatment of these strictures by gastric interposition is achievable with minimal morbidity.

Anterior fundoplication at the time of congenital diaphragmatic hernia repair

PURPOSE

The loss of normal anatomic barriers in neonates with congenital diaphragmatic hernia (CDH) can predispose children to gastroesophageal reflux (GER). In an attempt to improve post-operative feeding, we have added a modified anterior fundoplication to restore natural gastric and esophageal positioning.

METHODS

The institutional review board of both participating centers approved this study. Between 1997 and 2008, 13 neonates with high-risk anatomy underwent repair of CDH combined with an anterior fundoplication (Boix-Ochoa). The anatomic indications for concomitant fundoplication were absence of an intra-abdominal esophagus, an obtuse angle of His, and a small, vertically oriented stomach.

RESULTS

Ten patients survived to discharge and eight were on full oral nourishment. One required partial gastrostomy feedings for an improving oral aversion and quickly progressed to full oral feedings. One patient with chromosomal anomalies and swallowing dysfunction remained on long-term bolus gastrostomy feedings. Two with progressive symptoms of GER and failure to thrive required conversion to a 360 degrees wrap after 18 months of medical management. This was performed in conjunction with a planned, staged muscle flap reconstruction in one patient. There were no complications related to the fundoplication.

CONCLUSION

Anatomic predictors of severe GER can be efficiently countered at the time of CDH repair. A modified fundoplication should be considered in the operative management of high-risk infants.

Gastrointestinal tract feeding access and the role of fundoplication in combination with gastrostomy

PURPOSE OF REVIEW

Feeding access and associated antireflux procedures continue to be some of the most common operations performed in pediatric patients. This review will discuss the various feeding access procedures available, including minimally invasive techniques, and further elaborate on appropriate indications for a concurrent antireflux procedure as well as alternatives to fundoplication.

RECENT FINDINGS

Gastrostomy and jejunostomy can be successfully placed using endoscopic or laparoscopic techniques with low complication rates. Nissen fundoplication is well described laparoscopically but failure with recurrent gastroesophageal reflux has resulted in the development of other operative alternatives.

SUMMARY

Decisions concerning appropriate long-term feeding access must be individualized, understanding the advantages and disadvantages of gastrostomy and jejunostomy techniques. Laparoscopic Nissen fundoplication is successful for treatment of patients who fail medical therapy of gastroesophageal reflux, but recurrent gastroesophageal reflux is a persistent problem that requires innovative solutions.
