Surgical management of reflux strictures of the esophagus in childhood

Efficacy and Safety of Endoscopic Intralesional Triamcinolone Injection for Benign Esophageal Strictures

Objectives

To evaluate the efficacy and safety of endoscopic intralesional triamcinolone injection (ITI) for benign esophageal strictures combined with endoscopic dilation (ED).

Methods

Online databases including MEDLINE, EMBASE, the Cochrane Library, and Web of Science were comprehensively searched for prospective randomized control trials (RCTs) between 1966 and March 2018. A meta-analysis was conducted according to the methods recommended by the Cochrane Collaboration.

Results

Six RCTs consisting of 176 patients were selected. Meta-analysis results showed that additional ITI had a significant advantage in terms of stricture rate and required ED sessions. Surgery-related and non-surgery-related strictures showed similar results. Additional ITI was not associated with significantly increased risk of complications.

Conclusions

Our meta-analysis showed that additional ITI therapy was supposed to be effective and safe for benign esophageal strictures as it reduced the stricture rate and required ED sessions. However, more RCTs are necessary to support these findings.

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.

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.

High dose intravenous methylprednisolone resolves esophageal stricture resistant to balloon dilatation with intralesional injection of dexamethasone

One of the most serious problems in patients with long-gap esophageal atresia or corrosive esophagitis is esophageal stricture, which may require esophageal resection and replacement. We describe two cases with persistent esophageal stricture successfully managed by high dose intravenous methylprednisolone following balloon dilatation. High-dose methylprednisolone with gradual tapering (daily 25, 15, 10, 5, 2 mg/kg for 4 days each) plus cimetidine and ampicillin for 1 week was intravenously administrated immediately after balloon dilatation of the esophageal stenosis. This was followed by oral prednisolone (daily 2, 1, 0.5 mg/kg for 1 week each) for persistent esophageal stricture. High dose intravenous methylprednisolone therapy was given to two patients. One patient was a 5-year-old boy with long-gap esophageal atresia who had undergone repair of the esophagus resulting in severe anastomotic stenosis of 3 cm in length. The other case was a 10-year-old boy with corrosive stenosis caused by alkali ingestion. Both patients had been requiring balloon dilatation of the esophagus with intralesional injection of dexamethasone every 3 weeks for more than 1 year to tolerate oral feeding. After the high-dose methylprednisolone protocol was initiated, the symptoms of dysphagia or choking dramatically improved in both patients, and they remained symptom-free for 8 and 7 months. There were complications of moon faces that resolved concomitantly with the withdrawal of oral prednisolone in both cases. High dose intravenous methylprednisolone in addition to intralesional injection of dexamethasone following balloon dilation is an effective therapeutic strategy for persistent esophageal strictures.

Gastroesophageal reflux strictures in children, management and outcome

Esophageal reflux (GER) strictures are frequently diagnosed late and require a prolonged management programme depending on the severity of the stricture. Management protocols include medical therapy, bouginage, fundoplication, stricture resection and even interposition grafting. Our preferred method is to delay the anti-reflux surgery until the esophagitis is medically controlled, adequate enteral intake with weight gain is achieved and the oesophageal narrowing adequately dilated. We review the results of the approach over a 27-year period (1977-2004).

METHOD

Thirty-one children were treated (mean age at diagnosis 35 months). Diagnosis of GERD was made on barium meal and confirmed by pH studies, gastroesophageal scintigraphy and oesophagoscopy. Stenosed site, its length and nature (i.e. response to dilatation) were documented. Dilatations were carried by prograde, balloon and string-guided techniques. Three fundoplication techniques were used (Boix-Ochoa, Toupet and Nissen).

RESULTS

Twenty-two strictures were in the lower third, seven in the mid-third and two in the upper third of the oesophagus. Thirteen (42%) had associated hiatus hernia (HH). Twenty (64%) had a stricture length>3 cm. Twelve strictures were so severe (tight) as to require gastrostomy and string-guided dilatation. An average 5.5 dilatations were required prior to surgery. Only six children did not require post-surgery dilatation. Twelve required more than five post-operative dilatations. Reasons for stricture persistence were identified as failed reflux surgery in seven, candida oesophagitis in two, HIV infection in one and severity of fibrosis in three (two requiring stricture resection). At average follow-up of 5 years, all patients have restored growth without further symptoms.

CONCLUSION

Strictures are a major complication of GER requiring prolonged and intensive management in most cases. Reasons for persistence of stricture after anti-reflux surgery can be identified and require early intervention. Long-term follow-up is essential but results have been good in our hands.

Reflux strictures of the oesophagus in children: personal experience with preoperative dilatation followed by anterior funduplication

INTRODUCTION

Oesophageal surgery for reflux stricture is as challenging in adults as in the paediatric age group. Several management protocols, both medical and surgical, are currently proposed, such as bougienage, funduplication without dilatation, funduplication with pre- and postoperative dilatation, resection and interposition, and pharmacological therapy. However, reported results are not univocal. The aim of this work is to demonstrate that preoperative treatment with H2-antagonist combined with oesophageal dilatation and followed by anterior funduplication (Boix-Ochoa procedure with elongation of intraabdominal segment of the oesophagus) is a long-term, effective treatment for reflux stricture in children. It provides a tension free repair and an adequate protection to reflux, thus, preventing recurrences.

MATERIALS AND METHODS

In the last five years we observed oesophageal stenosis in 10 out of 49 children, operated for gastroesophageal reflux (mean age 62.9 months, range 12-156 months). All children underwent treatment with H2-antagonist (Ranitidine) and prokinetic agent (Cisapride), followed by oesophageal dilatations (mean 2.8, range 2-4 cycles) with Savary-Gillard dilators. An open anti-reflux procedure was performed (9 Boix-Ochoa and 1 Nissen) on children where a 9 mm endoscope passed easily through the oesophageal lumen. The pre and postoperative evaluation of all patients included symptoms assessment, esophagogram and endoscopy.

RESULTS

Results were satisfactory in 9 patients. Only one patient where a Nissen wrap was performed, incomplete relaxation was documented radiologically. The patient required several dilatations for residual dysphagia before reaching a symptom free status. All other patients had an average follow-up of 38 months (range, 5 months to 5 years) with relief from dysphagia and no recurrence of stricture. Radiological controls showed good oesophageal lumens, with normally positioned neocardias, opening regularly during barium passage with no sign of reflux. Multiple biopsies from endoscopic controls confirmed complete relief from oesophageal stricture but persistence of Barrett's mucosa.

CONCLUSIONS

Our treatment of choice for reflux stricture is preoperative pharmacological therapy followed by series of dilatation with Savary-Gillard dilators till oesophagus is adequately dilated. Antireflux surgery is mandatory when a stricture is observed. We prefer a Boix-Ochoa funduplication with extensive transhiatal mobilization of thoracic oesophagus. This results in a "tension free" fundoplication even when brachioesophagus is present. The procedure appears to be physiological for pediatric patients and in our hands was free from recurrences.

Laparoscopic fundoplication and gastrostomy

Minimally invasive surgical approaches to various pediatric surgical disease processes are becoming the standard of care. Laparoscopic Nissen fundoplication is transitioning toward the preferred method for the surgical correction of gastroesophageal reflux (GER) disease in infants and children that do not respond to medical management or have complications from their GER. This approach offers a shorter hospitalization, reduced discomfort, and cosmetic advantages when compared with the open operation. This report discusses the pathophysiology of GER, its clinical manifestations, and the diagnostic evaluation for this disorder. Also, the laparoscopic Nissen fundoplication technique currently utilized at Children's Mercy Hospital is described.

Gastroesophageal reflux in childhood

Gastroesophageal reflux (GER) is one of the most frequent symptomatic clinical disorders affecting the gastrointestinal tract of infants and children. During the past 2 decades, GER has been recognized more frequently because of an increased awareness of the condition and also because of the more sophisticated diagnostic techniques that have been developed for both identifying and quantifying the disorder. Gastroesophageal fundoplication is currently one of the three most common major operations performed on infants and children by pediatric surgeons in the United States. Normal gastroesophageal function is a complex mechanism that depends on effective esophageal motility, timely relaxation and contractility of the lower esophageal sphincter, the mean intraluminal pressure in the stomach, the effectiveness of contractility in emptying of the stomach, and the ease of gastric outflow. More than one of these factors are often abnormal in the same child with symptomatic GER. In addition, in patients with GER disease, and particularly in those patients with neurologic disorders, there appears to be a high prevalence of autonomic neuropathy in which esophagogastric transit and gastric emptying are frequently delayed, producing a somewhat complex foregut motility disorder. GER has a different course and prognosis depending on the age of onset. The incompetent lower esophageal sphincter mechanism present in most newborn infants combined with the increased intraabdominal pressure from crying or straining commonly becomes much less frequent as a cause of vomiting after the age of 4 months. Chalasia and rumination of infancy are self-limited and should be carefully separated from symptomatic GER, which requires treatment. The most frequent complications of recurrent GER in childhood are failure to thrive as a result of caloric deprivation and recurrent bronchitis or pneumonia caused by repeated pulmonary aspiration of gastric fluid. Children with GER disease commonly have more refluxing episodes when in the supine position, particularly during sleep. The reflux of acid into the mid or upper esophagus may stimulate vagal reflexes and produce reflex laryngospasm, bronchospasm, or both, which may accentuate the symptoms of asthma. Reflux may also be a cause of obstructive apnea in infants and possibly a cause of recurrent stridor, acute hypoxia, and even the sudden infant death syndrome. Premature infants with respiratory distress syndrome have a high incidence of GER. Esophagitis and severe dental carries are common manifestations of GER in childhood. Barrett's columnar mucosal changes in the lower esophagus are not infrequent in adolescent children with chronic GER, particularly when Heliobacter pylori is present in the gastric mucosa. Associated disorders include esophageal dysmotility, which has been recognized in approximately one third of children with severe GER. Symptomatic GER is estimated to occur in 30% to 80% of infants who have undergone repair of esophageal atresia malformations. Neurologically impaired children are at high risk for having symptomatic GER, particularly if nasogastric or gastrostomy feedings are necessary. Delayed gastric emptying (DGE) has been documented with increasing frequency in infants and children who have symptoms of GER, particularly those with neurologic disorders. DGE may also be a cause of gas bloat, gagging, and breakdown or slippage of a well-constructed gastroesophageal fundoplication. The most helpful test for diagnosing and quantifying GER in childhood is the 24-hour esophageal pH monitoring study. Miniaturized probes that are small enough to use easily in the newborn infant are available. This study is 100% accurate in diagnosing reflux when the esophageal pH is less than 4.0 for more than 5% of the total monitored time.

Reflux strictures of the esophagus in children

Although the therapeutic approach to gastroesophageal reflux in children is well established, there are differences of opinion regarding the management of esophageal strictures, viz bougienage with medical therapy, fundoplication without dilatation, preoperative dilatation followed by fundoplication with intraoperative and postoperative dilatation, or resection and interposition. Sixteen consecutive children (mean age, 30.2 months) with reflux strictures were evaluated, constituting 12% of children operated on for gastroesophageal reflux. The strictures became clinically apparent 22.4 months (mean) from the onset of symptoms and were diagnosed by contrast studies and endoscopy. At first endoscopy all the patients had well-established fibrotic strictures. The strictures were mostly situated in the middle or lower esophagus and 7 were longer than 3 cm in length. All 16 were treated with antacids, H2-receptor blockers (Cimetidine), prokinetic agents, and intense nutritional resuscitation, together with preoperative stricture dilatations (average, 3.6 times). This was followed by fundoplication when nutritional parameters had been restored, esophagitis improved, and the strictures dilated to adequate size. Seven children required concomitant gastrostomies for prograde esophageal dilatations. Twelve children needed postoperative esophageal dilatations. The results were satisfactory in 14 (88%). Two required endoesophageal resection for localized unyielding strictures. One child responded only after failed reflux surgery was corrected at a second procedure. During an average follow-up of 8.2 years (range, 3 to 11) there has been no stricture recurrence and growth velocity was restored in all. We conclude that our preferred method is preoperative in-hospital management of gastroesophageal reflux with maximum nutritional support and careful evaluation of the degree and extent of esophagitis and fibrous scarring.(ABSTRACT TRUNCATED AT 250 WORDS)

Persistence of Barrett's esophagus in children after antireflux surgery: influence on follow-up care

Adenocarcinoma arising in Barrett's esophagus has recently been described in two children aged 11 and 14 years. The long-term follow-up of Barrett's esophagus in children is not well described. We evaluated 16 cases of Barrett's esophagus in children treated at this institution during the last 16 years. Ages ranged from 1.2 to 16 years (mean, 10.3 years). There were 11 boys and 5 girls. Barrett's esophagus was documented by endoscopy in 14 instances and at autopsy in 2 patients with secretory diarrhea and tetralogy of Fallot who died of sepsis. Two children had cancer (neuroblastoma, leukemia) and died of their malignant disease. Five patients had cerebral palsy, 1 esophageal atresia, 1 Fanconi's anemia, and 5 were otherwise normal children. Six were treated medically. Eight patients underwent Nissen fundoplication for complications of gastroesophageal reflux (GER). Five patients were available for follow-up endoscopy (mean, 2 years; range, 1.1 to 5.4 years). Endoscopy was performed on a yearly basis, obtaining biopsy specimens from multiple levels of the esophagus. Four children had satisfactory clinical response to an antireflux procedure including the resolution of a stricture in one case. However, in all 5 cases persistent metaplastic epithelium was documented and showed no evidence of regression. Although there has been speculation that Barrett's esophagus in children may be more likely to revert to normal squamous epithelium than in the adult, there has been only one case of regression in 180 cases of Barrett's esophagus occurring in children described in 37 reports in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term follow-up of brain-damaged children requiring feeding gastrostomy: should an antireflux procedure always be performed?

Due to the frequent presence of latent gastroesophageal reflux (GER) in mentally impaired children, it is now standard to perform upper gastrointestinal contrast (UGI) and pH probe studies in all children referred for feeding gastrostomy, even if they are without clinical evidence for GER. For patients with documented GER, an antireflux operation performed in conjunction with gastrostomy is usually considered mandatory. Some authors have suggested that a "protective" antireflux operation be performed at the time of gastrostomy placement in all brain-damaged children, citing a high incidence of postoperative GER in this group of patients following gastrostomy, even with a negative preoperative evaluation for GER. To evaluate this theory, we prospectively studied, over the past 6 years, all mentally retarded children referred for feeding gastrostomy with UGI contrast and esophageal pH probe studies. In total, 148 children were studied; 105 had a positive evaluation for GER and underwent gastrostomy and antireflux surgery. Of the 43 children with a negative preoperative evaluation for GER, 37 are doing well following gastrostomy alone without clinical reflux at an average follow-up of 21 months. Six of the 43 (14%) developed symptomatic GER occurring at an average of 10 months following gastrostomy placement. Five of these children have been successfully treated with an antireflux operation and the sixth patient has been successfully managed nonoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgical treatment of reflux stricture of the esophagus

Ten children, aged 7 months to 15 years, with peptic esophageal stricture, were treated surgically. In four of the children, the stricture had occurred after esophageal anastomosis. Peptic stricture was diagnosed by esophagography, pH monitoring, manometry, and esophagoscopy. Barrett's esophagus was found in two children. Nine children underwent transabdominal Nissen fundoplication initially. In the first child of this series, a tight anastomotic stricture had been excised 2 weeks before fundoplication. Seven children became complaint-free within 2 or 3 months after fundoplication without any dilatation, and two children with anastomotic stricture improved after 1 or 2 postoperative dilatations. The condition of one boy, with a 6-year history of tight stricture, did not improve with repeat Nissen and subsequent dilatations. Histological examination showed proliferation of smooth muscle cells in the submucosa. A conservative surgical approach is effective for the management of peptic esophageal stricture in children, and direct surgical intervention for stricture should be attempted only in cases of stricture resistant to antireflux surgery with a long history of reflux.

Prognostic risk factors for graft failure following pancreas transplantation: results of multivariate analysis of data from the International Pancreas Transplant Registry

A multivariate analysis of prognostic factors for graft failure was performed on patients in the International Pancreas Transplant Registry. The analysis was restricted to the period January 1978 to June 1987 and included 764 patients. All patients had at least 1 year of follow-up. The following variables were studied: transplant year, continent (N. America, Europe, others), type of donor (cadaver, living related mismatched, living related HLA-identical), donor mismatch at the HLA A, B loci, donor mismatch at the DR loci, preservation time, kidney association (pancreas transplant alone, simultaneous pancreas and kidney transplant, pancreas after kidney transplant), whole versus segmental pancreatic transplant, graft duct management technique (polymer injection, enteric drainage, stomach drainage, bladder drainage), and immunosuppression. By stepwise, logistic regression analysis, we found that the following factors were predictive for 1-year graft function: donor mismatch at the DR loci (P = 0.0003), kidney association (P less than 0.0001), type of donor (P = 0.04), and immunosuppression (P = 0.0002). For donor mismatch at the DR loci, we found an odds ratio for success of 2.2 for 0 versus 2 mismatches. The odds for success were 2.9 for simultaneous pancreas and kidney transplant versus pancreas transplant alone. The best results--79% 1-year graft survival--were obtained for the combination of 0 mismatches at the DR loci, pancreas after kidney transplant, living related HLA-identical donor, and the immunosuppressive regimen consisting of cyclosporin, azathioprine, and prednisone. Patients receiving a pancreas transplant alone with 0 mismatches at the DR loci, living related HLA-identical donor, and triple immunosuppressive regimen had a predicted 1-year graft survival of 71%.

Gastric vascular pedicle patch esophagoplasty for stricture

Three patients with Barrett's esophagus and strictures between the middle and distal thirds of the esophagus, of 5 to 26 years duration at the time of the plasty, were treated with an infradiaphragmatic Nissen fundoplication and gastric vascular pedicle patch esophagoplasty, based on the right gastroepiploic vessels. Follow-up for 2 patients has been 6 and 7 years; both patients are asymptomatic except for periodic mild dysphagia in 1. The third patient developed cancer after 1 symptom-free year, and had esophagectomy with colon interposition. The results of this operation justify its use in recalcitrant lower intrathoracic esophageal strictures that do not respond to antireflux operation or dilation.

Successful management of esophageal strictures without resection or replacement

Esophageal resection or replacement has become the standard therapy for severe esophageal strictures chiefly because less aggressive methods generally have failed. We hereby report our experience with 12 consecutive infants and children who have been managed successfully by means of Stamm gastrostomy and string-guided esophageal dilatation, coupled with endoscopically guided four-quadrant intralesional steroid injection, protected by Nissen fundoplication when gastroesophageal reflux has been demonstrated. In six patients, the stricture(s) were caused by ingestion of lye. In five, they were associated with repair of esophageal atresia. In one, the etiology was never determined. The strictures averaged 3.5 cm in length (range, 1 to 10 cm); the severity of the lesions was indicated by the fact that, in all instances, patients were completely intolerant of solids, and was confirmed fluoroscopically by demonstration of significant luminal narrowing. A mean of 4.3 steroid injections (range, 1 to 8) was required to obtain complete remission of symptoms; there have been no complications except in one lye ingestion patient who developed a tiny perforation following the initial dilatation, which responded to antibiotics alone. All patients remain symptom-free; the mean length of follow-up is 6.2 years (range, 1 to 11 years). We conclude that string-guided esophageal dilatation, when coupled with endoscopically guided steroid injection, is a safe and reliable method for treatment of severe esophageal strictures, which should obviate the need for esophageal resection or replacement in most patients. Moreover, even if treatment should ultimately fail, a procedure of lesser magnitude than esophageal replacement will likely be possible.(ABSTRACT TRUNCATED AT 250 WORDS)

Adhesion obstruction following Nissen fundoplication in children

The incidence of postoperative adhesion intestinal obstruction among 156 children who had undergone Nissen fundoplication for intractable gastro-oesophageal reflux was determined. There were 18 episodes of obstruction in 16 patients (10.3 per cent). The mean interval between fundoplication and adhesion obstruction was 10 months (range 10 days-4 years). Additional procedures performed at the original laparotomy substantially increased the risk of developing obstruction. Relaparotomy for adhesion obstruction was required by 21 per cent of patients who had a Ladd's procedure and 12 per cent who had appendicectomy. Presenting symptoms were not typical of intestinal obstruction because many of these children were unable to vomit. Only three did vomit but all had radiological appearance suggestive of small bowel obstruction. There were two deaths directly related to adhesion obstruction.

Results and complications of surgery for gastro-oesophageal reflux

One hundred and six children undergoing antireflux surgery were studied; 41 were severely mentally retarded and 29 had reflux strictures. Although the eventual rate of success was 92%, 20 patients developed complications that required a second operation. Prolapse of the fundoplication into the mediastinum was the commonest complication (in seven patients), followed by intestinal obstruction (in five), and intractable fibrous oesophageal strictures (in five). The incidence of postoperative complications was highest in patients with mental retardation or oesophageal strictures. Referral of these patients for operation was invariably delayed, and earlier referral may have avoided many of the complications.

Jejunal interposition for recurrent gastroesophageal reflux in children

There is limited experience with surgical treatment for recurrent gastroesophageal reflux after an antireflux procedure. In four pediatric patients with recurrent reflux after surgical therapy, interposition of an isoperistaltic segment of jejunum produced excellent short-term results. Further follow-up is needed as experience broadens. At the present time, this procedure merits consideration in patients with recurrent gastroesophageal reflux.
