The treatment plan for each baby must be individualized. The prognostic classifications (see Indications for and Timing of Surgical Intervention below) can provide guidance in patients with multiple problems, but early and decisive identification of the most life-threatening anomaly is essential.
Management plans for a delayed repair of the esophageal atresia may include placing a 10-French Replogle double-lumen tube through the mouth or nose well into the upper pouch to provide continuous suction of pooled secretions from the proximal portion of the atretic esophagus. The baby may be positioned in the 45° sitting position. Prophylactic broad-spectrum antibiotics (eg, ampicillin and gentamicin) may be used. General supportive care and total parenteral nutrition are needed.
With careful bedside attendance, these measures may permit a delay of days to perhaps weeks. Some have described cases in which the baby was discharged home with a Replogle tube in situ while waiting for staged repair of an esophageal atresia. However, deaths have been reported in infants in whom the tube did not maintain an empty upper pouch. A gastrostomy, distal tracheoesophageal fistula (TEF) ligation, or cervical esophagostomy may permit longer delays in the esophageal atresia repair. However, each intrusion carries a price.
If no distal TEF is present, a gastrostomy may be created. In such cases, the stomach is small, and laparotomy is required. In all cases of esophageal atresia in which a gastrostomy is created, care should be taken to place it near the lesser curvature to avoid damaging the greater curvature, which can be used in the formation of an esophageal substitute. When a baby is ventilated with high pressures, the gastrostomy may offer a route of decreased resistance, causing the ventilation gases to flow through the distal fistula and out the gastrostomy site. This condition may complicate the use of ventilation.
In cases such as those above or in cases in which a distal fistula continues to cause lung soiling, distal TEF ligation should be considered. This ligation is performed by means of a right-side thoracotomy, ideally via an extrapleural approach. The fistula may be clipped or simply ligated. If it is ligated and divided, subsequent staged repair of the esophageal atresia may be difficult because the distal esophageal segment tends to retract inferiorly to a substantial degree when it is detached from its tracheal mooring. However, simple fistula ligation may allow subsequent reopening of the fistula. Division of the fistula and attempts to anchor it at the midchest with sutures are usually unsuccessful.
A cervical esophagostomy or spit fistula may be constructed in the right or left side of the neck, depending on the choice for subsequent esophageal substitution. It allows drainage of the upper pouch and precludes aspiration from the upper pouch. Sham feeding may be commenced in cases in which a long delay to repair is anticipated. This feeding may prevent subsequent oral aversion, which is a real problem in babies who have not been fed by mouth in their early weeks to months of life. However, cervical esophagostomy usually dooms the child to some form of esophageal substitution.
Future and controversies
The future is bright, with the following considerations: More accurate prenatal diagnosis and prenatal treatment may be possible. Minimally invasive techniques for repair with thoracoscopic surgery are now used in some centers, with good results. A better understanding of the pathoembryologic processes of this condition may reveal its causative agents or genetic factors. This knowledge, in turn, may lead to specific prenatal treatments or preventive techniques. In recent years, the incidence of this disorder has decreased, perhaps because of increased usage of prenatal folic acid supplements.
Debates continue about the best operative technique (eg, right-side or left-side thoracotomy) for patients with right-side aortic arches, suture type and technique, esophageal lengthening strategies, and procedures for mobilizing the distal esophagus. Other discussions include when to use cervical esophagostomy and the choice of esophageal replacement. The advent of esophageal atresia repairs that combine both minimally invasive and radiologic interventional techniques may be near.
The management of gastroesophageal reflux (GER) in esophageal atresia is particularly challenging; some advocate aggressive fundoplication, and others prefer more conservative medical treatment. In addition, the true incidence and treatment of tracheomalacia continues to be the subject of debate. Finally, the proper evidence-based guidelines for long-term follow-up are still elusive.
Tissue engineering of the esophagus may offer solutions for replacement of lost esophageal tissue.[26, 27, 28] Experimental studies have shown promising results in the culture of esophageal epithelial cells and esophageal smooth muscle cells. Viability of these cell on biodegradable scaffolds in vitro may provide the necessary replacement esophageal tissue in future. Studies in large animal models have shown promising results in the generation of rudimentary esophageal tissue using tissue engineering and regenerative medicine technology.
Indications for and Timing of Surgical Intervention
The indication and timing of surgical repair may be determined by using the Waterston, Spitz, or Poenaru prognostic classification system.
In 1962, Waterston developed a prognostic classification system for esophageal atresia that is still used today. Category A includes patients who weigh more than 5.5 lb (2.5 kg) at birth and who are otherwise well; category B includes patients who weigh 4-5.5 lb (1.8-2.5 kg) and are well or who have higher birth weights, moderate pneumonia, and congenital anomalies; and category C includes patients who weigh less than 4 lb (1.8 kg) or have higher birth weights, severe pneumonia, and severe congenital anomalies. Management strategies are as follows:
Category A - Immediate primary repair
Category B - Delayed repair
Category C - Staged repair
In 1994, after analyzing findings in 387 patients, Spitz et al recognized that the presence or absence of cardiac disease is a proven major prognostic factor. Accordingly, they suggested the following groups, which are analogous to those in the Waterston classification system:
Group I - Birth weight >1.5 kg and no major cardiac disease
Group II - Birth weight <1.5 kg or major cardiac disease
Group III - Birth weight <1.5 kg and major cardiac disease
In 1993, Poenaru proposed a simple, two-group classification system based on logistic regression analysis findings in 95 patients. Class I included patients who are low-risk and do not meet criteria in class II, and class II included patients who are high-risk and ventilator-dependent or who have life-threatening anomalies, regardless of pulmonary status. Birth weight was not included as a factor.
In 1989, Randolph et al refined the Waterston classification and reported a clinically helpful system that used a patient's physiologic status to determine surgical management (ie, immediate repair, delayed primary repair, or staged repair). Weight, gestational age, and pulmonary condition were not considered. If the patient's physiologic parameters were good, they were managed with immediate repair. Staged repairs were used for infants who were severe compromised infants, especially those with severe cardiac anomalies. In this group, the survival rate was 77%, and the overall survival was 90%.
The aforementioned prognostic groupings can allow for the stratification of high-risk patients with esophageal atresia in planning for delayed repair, staged repair, or both; low-risk babies can usually undergo early (ie, within the first 24-48 hours) primary single-stage repair. For instance, a 2-kg baby with esophageal atresia and distal TEF who also has tetralogy of Fallot is in Waterston category C, Spitz group II, and Poenaru class II; in this patient, delayed or staged repair may be best.
These classification systems help physicians to compare results in an organized and meaningful way. When the three prognostic classification systems are compared, the Spitz classification appears to have the most applicability in current practice. Ductal-dependent cardiac lesions still seem to significantly affect the survival of children born with esophageal atresia.
Potter syndrome is bilateral renal agenesis and carries a 100% mortality; therefore, repair of esophageal atresia is contraindicated.
Options for Surgery
This section provides some details about surgical approaches for the repair of the most common type of esophageal atresia (ie, esophageal atresia with distal TEF) in low-risk patients. Surgical techniques vary according to surgeons' preferences and variations in pathologic anatomy. Modifications for special anatomic challenges are briefly discussed. In particular, infants born with esophageal atresia without fistula represent a specific and challenging subgroup. These babies should undergo an early gastrostomy procedure in the newborn period. A gapogram (see Workup) should be performed to assess the prospects for anastomotic repair. (See the image below.)
In infants with atresia without fistula, surgical decisions must be made regarding the following :
Length of time to wait for the ends to grow closer
Whether to perform one of numerous esophageal lengthening procedures, such as the Kimura, Livaditis, Scharli, or Foker procedures
Whether to perform an esophageal substitution procedure, with or without the formation of a cervical esophagostomy
Whether to use a gastric tube (reversed and proximally based or antegrade and distally based)
The use of colonic (left chest or substernal), gastric pull-up, or jejunal vascularized graft segments is difficult and should be based on the condition of the infant, the pathologic anatomy, associated defects (eg, gastric pull-up is usually contraindicated in significant cardiac disease, and colonic esophageal replacement is usually contraindicated with concomitant imperforate anus), and the surgeon's experience.
As a rule, a child's own esophagus is better than any substitution. Favorable reports of the Foker technique used for serial dynamic lengthening in cases of long gaps suggest that advantage.[36, 37, 38] The Foker technique involves two thoracotomies. First, anchoring sutures are placed securely at the two ends of the atretic esophagus and brought out diagonally to the chest wall. Over a period of days to weeks, the two ends are brought closer together through a series of daily lengthenings achieved by traction on the exposed sutures. The closure of the gap is monitored radiologically with radiopaque markers at the atretic ends. A second thoracotomy is then performed to effect a tension-free anastomosis.
The preparation of a 1-day-old neonate for surgery includes the following measures:
Intravenous (IV) fluid containing an adequate glucose concentration (ie, 10% glucose) is administered at a rate appropriate for the neonate's gestational age and weight
Prophylactic broad-spectrum IV antibiotics (eg, ampicillin, gentamicin) are administered
The neonate is kept warm by using an incubator or overhead warmer and is positioned supine in the Fowler position, with the head elevated by approximately 45°
A 10-French Replogle tube is placed nasally or orally well into the upper pouch and is connected to a continuous suction device; every 30 minutes, the tube is checked for patency first by suctioning with an empty syringe and then by gently injecting 5 mL of air (never water); in small infants, an 8-French double-lumen tube may be used instead
The parents should be fully briefed about the nature of the congenital anomaly; a diagram is invaluable for explaining not only the pathologic anatomy and intended repair but also the possible complications; parents' consent for treatment should be obtained, and the discussion with them should be documented in appropriate detail on the baby's medical record
Bronchoscopy performed just before repair of the esophageal atresia may enable the following:
Detection of an upper-pouch fistula
Localization of the distal fistula, which usually lies at a level just above that of the carina
Detection of an aberrant right-upper-lobe bronchus emanating from the trachea, which is not uncommon in cases of esophageal atresia
Early assessment of the cross-sectional shape of the trachea, which may help in determining the risk of significant postoperative tracheomalacia
Assessment of specific vascular anomalies (eg, right-side aortic arch, aberrant right subclavian artery [for which one looks for the pattern of pulsation on the tracheal wall])
Identification of laryngotracheoesophageal cleft
The infant is endotracheally intubated without paralysis. The anesthesiologist must be mindful of the distal fistula. With skill, the long end of the distal endotracheal tube bevel may be positioned over the fistula to decrease the passage of gases into the stomach. This maneuver helps prevent gastric distention, maximizes ventilation, and minimizes the chances of a gastric perforation.
As much as possible, the baby should be allowed to spontaneously breathe until the fistula is occluded. In reality, and especially because the chest is open and the lung is retracted, the anesthesiologist manually assists with the baby's ventilation. However, mechanical ventilation should be avoided until the fistula is controlled. This procedure requires great skill, experience, and focus on the part of an anesthesiologist in caring for these babies in the operating room.
Managing infants with premature lungs
In positioning the baby in full right thoracotomy position, the surgeon must ensure that the anesthesiologist has full and easy access to the infant's nose and to the Replogle tube, which is not taped so that it can move in or out. If a right-side aortic arch is detected preoperatively, controversy exists about whether a left thoracotomy provides easier access. A left-side approach has its merits, but in this instance, the esophagus is still a right-side structure, and access from the right is best.
Finally, the baby is covered with antiseptic solution, and drapes are placed so as to expose the areas from the nipple to the midback and from the axilla to the 10th rib.
The surgeon should wear magnification loupes. The assistants and nurses should be briefed about their duties and about special points of care regarding the delicate nature of the procedure and the baby's tissues.
A transverse right thoracotomy incision is made from the anterior axillary line to approximately one fingerbreadth posterior to the posterior axillary line at a level 1 cm inferior to the palpable tip of the scapula. The latissimus dorsi is divided with the coagulating current of the electrocautery device. The fascia lying just posterior to the posterior margin of the serratus is divided with the electrocautery, and the serratus is retracted anteriorly. Usually, an incision in the serratus is not needed.
The scapula is then lifted away from the chest wall, and the ribs are counted from the first to the fourth. Ideally, the chest is entered through the fourth interspace. With careful use of forceps and the electrocautery device, the outer and innermost intercostal muscles are divided in this interspace down to the parietal pleura.
By using either moist sponges or peanut gauze on the forceps, the parietal pleura is dissected away from the chest wall, proceeding posteriorly but also dissecting somewhat superiorly and inferiorly as well. A small mechanical Finochietto-type rib retractor is placed in the open thoracotomy site, and the pleural dissection proceeds to a point medial to the azygos vein.
If the preoperative echocardiogram demonstrates normal venous return from the inferior vena cava, then the azygos vein is ligated and divided with fine silk. If there is evidence of an interrupted inferior vena cava, then the azygos vein may represent the patient's primary venous return from the lower body, and test occlusion of the azygos vein should precede ligation.
The extrapleural dissection then allows retropleural repair of the esophagus. If an anastomotic leak occurs, it tends to be more contained as compared with the empyema that results if the repair is performed transpleurally.
At this point in the dissection, the anatomy is defined first by having the anesthesiologist push on the indwelling Replogle tube; this action usually reveals the upper pouch that rhythmically bulges out in the apex of the right chest cavity. The distal fistula is usually located near the level of the carina and lies just beneath the divided azygos vein. It expands slightly with each inspiration. One must take great care not to mistake the aorta for the fistula. Mistaken ligation of the aorta is possible; in case of doubt, a 25-gauge needle can be passed into the structure to check.
Gaining control of the fistula now relieves the anesthesiologist. A silicone rubber vessel loop can be passed around the fistula at a convenient level near the trachea. Gentle retraction on this occludes the fistula. Most advise division of the fistula with suturing of its tracheal aspect. This division can be accomplished by cutting into the fistula as it enters the back wall of the trachea in short snips and by oversewing the tracheal aspect as it opens in stages. Usually, about four interrupted sutures suffice. Most advocate the use of an absorbable synthetic suture material such as polyglactin. This sutured fistula site may be covered with an azygos or pleural patch for extra security.
The fistula closure should be checked by covering the closure in saline and manually ventilating the patient for a Valsalva test. If bubbles appear, the closure is leaking and must be resutured. Turning his or her attention to the upper pouch, the anesthesiologist can again push on the Replogle tube to facilitate placement of a traction suture into the distal end of the upper pouch.
The upper pouch is then circumferentially dissected cephalad to increase its length. Blood supply to the upper portion is linearly arrayed from the cervical and subclavian vessels; ischemia is not a concern. This dissection must be carefully performed between the pouch and the trachea while the presence of an upper pouch fistula that emanates from the side (not the end) of the pouch is determined. Also, the back wall of the trachea may be inadvertently entered. This condition is repairable with absorbable sutures.
Avoid extensive dissection of the distal end because its blood supply is segmental from the aorta, and it can easily become ischemic. A gap between the ends may seem to be present. If it is very lengthy, the muscular covering of the upper pouch may be cut without entry into the lumen to obtain 1 cm or so of additional length. Distal dissection may be performed; the risk of ischemia should be recognized. If absolutely necessary, the two ends may be simply bridged using two stout silk sutures in the hopes that they form a fistula and that they can be dilated to form a functional esophagus. More commonly, the two ends are reasonably close, and an anastomosis is possible.
The distal portion of the upper pouch is cut off, and the proximal portion of the distal segment is trimmed. The mucosal and muscularis layers of the esophagus should be carefully sutured together in a single layer to form an anastomosis with simple interrupted stitches. Once again, most advocate the use of an absorbable synthetic suture with a caliber of approximately 5-0 (eg, braided polyglactin). The back wall is sutured, and the upper pouch tube is passed through the half-completed anastomosis into the stomach to help rule out a distal stricture and to empty the stomach of accumulated gas.
This tube is left in place as the anterior wall of the anastomosis is completed. The tube is then gently withdrawn from the body. Some advocate leaving the transanastomotic tube to act as a stent, though this tube may be partially moved, potentially injuring the anastomosis. A small-caliber 10-French chest tube may be left in place as an extrapleural chest drain. The ribs are reapproximated by encircling them with two 3-0 absorbable sutures and by restoring their normal anatomic position. The muscles and skin are closed in layers with absorbable sutures.
In some pediatric surgical centers, surgeons are gaining experience in repairing esophageal atresia by means of a minimally invasive thoracoscopic approach.[39, 40, 41, 42] This approach should be undertaken only by those who have extensive experience in pediatric thoracoscopic surgery.
The intubated patient is transported to the neonatal intensive care unit. Antibiotics are continued until the chest drain is removed, and the endotracheal tube is suctioned as necessary. Oral suctioning to a depth of no more than 7 cm from the lips is performed every half hour for the first day, then every hour or more frequently as necessary on the second day. Thereafter, it is performed as needed. Suctioning is required to handle the sometimes copious oral secretions that can build up in the first day or so after surgery. As the swelling of the esophagus settles, the secretions taper.
The chest draining tube is placed in 2 cm of water only to seal it; it is not connected to a suction device, which could encourage an anastomotic leak. Morphine is infused as necessary for the patient's comfort, and peripheral parenteral nutrition should be commenced. The endotracheal tube should remain until weaning from ventilation is ensured, usually after 1-2 days. Premature extubation and subsequent intubation in the setting of a freshly closed tracheal fistula invites reopening of the fistula.
Watch for saliva exiting out the chest drain; this is a signal of anastomotic leakage. Often, it is accompanied by visible distress. Signs of sepsis may or may not be present. A chest radiograph should be obtained. Provided that the baby is stable, a contrast-enhanced study of the esophagus with a water-soluble isotonic medium may be performed on day 5, 6, or 7 to assess for leaks and to view the caliber of the repair (see the image below).
If the esophagus is patent and reasonably sized, the baby may be orally fed; starting with expressed breast milk is ideal. Then, the chest tube is removed. As soon as the baby is feeding well, the IV line is discontinued, and the baby can be discharged. Oral ranitidine or a proton pump inhibitor (PPI) is often prescribed because of the propensity for GER in this group of patients and because of the risk of stricture as a secondary effect.
Early complications may include anastomotic leakage, recurrent TEF, and anastomotic stricture.
An anastomotic leak tends to occur 3-4 days after surgery. This leak has been reported in approximately 15% of cases. Pain and distress are often evident. Signs of sepsis may be present. The chest tube drains saliva. Treatment is supportive; appropriate antibiotics should be used, and the child should be given nothing by mouth. Surgery is not indicated, even with huge leaks. If the leak persists, esophagography may be performed with water-soluble contrast material to assess its magnitude.
The usual protocol is to wait and let the leak close. If an extrapleural approach was used, the child is usually less ill than with other approaches, and the resultant esophagocutaneous fistula closes within days. If a transpleural approach was used, then the child is more ill and has an empyema that may require further treatment and drainage. No absolute evidence indicates that postoperative leaks lead to anastomotic stenoses. For high-volume postoperative leaks, some studies reported successful use of the anticholinergic agent glycopyrrolate, which markedly reduced salivary production and facilitated leak closure.
Recurrent tracheoesophageal fistula
Recurrent TEF may occur within days; most often, it occurs weeks later. Its incidence has been variously reported as 3-14%. Its first manifestation may be pneumonia, although the child may cough and have respiratory distress with feeding. The diagnosis is made by means of esophagography performed with water-soluble contrast material under fluoroscopic guidance with the child prone. The contrast material is slowly injected through a catheter in the esophagus as the tube is slowly withdrawn, and lateral views are obtained by means of videofluoroscopy.
The recurrent fistula is observed as a wisp of contrast material that suddenly crosses over to the trachea. This so-called pull-back esophagography is the most accurate method for diagnosing a recurrent fistula. Bronchoscopy and esophagoscopy may provide supplementary information. One endoscopic technique is to inject 0.5 mL of methylene blue into the endotracheal tube and through the esophagoscope while watching for it to come through the fistula.
Historically, these fistulae were believed to require surgical repair by means of repeat right-side thoracotomy; however, the authors have been successful in a minority of cases of fistulae by allowing them to close spontaneously while maintaining the nothing by mouth restriction and while administering antibiotics for one week. Endoscopic cautery and fibrin glue have also been reported to be occasionally successful.
Anastomotic stricture has been reported in as many as 50% of cases, but the rate partially depends on the definition of stricture. Essentially, 100% of babies have a waist at the anastomotic site, but this may not be functionally significant. In cases in which the stricture appears to be functionally significant on oral contrast-enhanced studies, esophageal dilation is best and is most safely performed by means of a Grüntzig balloon technique under fluoroscopic control (in the authors' opinion).
This procedure should be performed by an experienced radiologist who can monitor the balloon pressure, position, and inflation diameter. In newborns, this technique of dilatation would best be deferred until the child is aged at least 6 weeks and for at least 4 weeks after the anastomosis. Alternatively, the balloon dilation technique can be performed under endoscopic and fluoroscopic guidance by the surgeon, a gastroenterologist, or both. Direct endoscopic visualization and passage of a guide wire past the area of the stricture help faciliate proper balloon placement and dilation.
Other methods involve the passage of tapered dilators of various sorts (eg, Tucker and Maloney dilators). Certainly, these methods can be effective, but they are performed in essentially a blind manner unless done under fluoroscopic control. They also involve longitudinal and radial force vectors, as opposed to the pure radial force vectors of the Grüntzig technique. Repeat dilations are often necessary. Histamine 2 (H2)-receptor blockade should be started because acid reflux can be both an aggravating and a causative factor in stricture formation.
Other factors to consider include the following:
Type of suture used
Length of the atretic gap
Ischemia of the distal portion
Whether an anastomotic leak may have occurred
Strictures resistant to a few dilations require more aggressive treatment, which may include an antireflux operation, stricture resection, or both; rarely, they necessitate esophageal replacement.
There have been anecdotal reports concerning injection of various agents (eg, triamcinolone and mitomycin C) to treat the dilated stricture medically and prevent recurrence. In one report, topical application of the antineoplastic agent mitomycin C was found to be effective in preventing stricture in refractory cases.
Stents have been used but are still investigational. Surprisingly, parents can be taught to perform regular Maloney dilations at home in selected cases.
Late complications may include GER, esophageal dysmotility, and tracheomalacia. Some of these complications may appear early.
GER is particularly problematic in patients with esophageal atresia because of congenital distal dysmotility of the esophagus, dysfunction of the physiologic antireflux barrier, possible partial vagotomy during surgery, or essential vagal dysfunction that can lead to delayed gastric emptying. Essentially all babies with esophageal atresia have detectable GER. Patients who require treatment must be carefully identified.
All babies with esophageal atresia should be prophylactically treated with ranitidine or a PPI (eg, omeprazole). Failure to thrive, coughing, choking spells, wheezing and asthma, recurrent pneumonias, vomiting, cyanosis, dying spells, excessive drooling, and apparent dysphagia are all indications to investigate the degree of GER. Oral contrast material should be administered, and endoscopy should be performed. Strictures should be dilated. A pH probe study may help if the probe is placed below any present stricture. A gastric emptying scan should be obtained. All factors should be carefully considered.
Surgical approaches to helping the child may include an antireflux operation. A partial-wrap fundoplication is usually preferred because of the dysmotility of the repaired esophagus. Dysphagia after even a very loose wrap is not uncommon. If the stomach has delayed emptying, balloon pyloroplasty or surgical pyloroplasty may be considered to speed emptying. The authors have used a surgically conservative approach in children with this condition; they prefer to treat the reflux medically with H2-receptor blockade or a PPI when possible. It is certain, however, that some patients require a surgical approach for later complications.
Esophageal dysmotility is an ongoing problem. It has various dysphagic manifestations. The children eventually learn that they must masticate thoroughly and drink fluids when eating. Food bolus obstructions, even without a significant stricture, are not uncommon in toddlers. Parents must be mindful of this possibility and choose their child's foods accordingly. The use of motility agents such as domperidone may help.
Tracheomalacia is a manifestation of disordered embryogenesis. In its severe form (occurring in ~10% of patients), dramatic signs include an inability to wean the patient from a ventilator and the classic dying spells in which the patient becomes pale and limp and, usually, apneic and cyanotic for a short time. Children with this condition require examination and treatment. Milder cases of tracheomalacia may cause recurrent pneumonias or asthma attacks, and in general respiratory ailments are common in these children.
Bronchoscopy performed while the patient is spontaneously breathing reveals a trachea that significantly collapses, flattens, or closes upon expiration. Treatment consists of aortopexy, which suspends the aortic arch to the underside of the sternum and thereby secondarily suspends the anterior tracheal wall anteriorly, preventing its collapse. If this is unsuccessful, stent placement may help, but this option is controversial. Tracheostomy is the final management option. Fortunately, tracheomalacia tends to improve with time, growth, and maturation.
If all is well with the patient and if the parents have been briefed on what to look for, a reasonable follow-up regimen may include the following steps:
The surgeon should make contact with the community physician who is responsible for the general medical care of the child and ensure that he or she is briefed on the baby's history, condition, and expected outcome
The nurse on the surgical team should follow up by telephone in 1 week
The surgeon should follow up in 1 month to interview the parents and generally assess the child's condition, growth, and healing at the surgical site
The patient should return at 3 months for a similar assessment
At a 1-year follow-up and general assessment, swallowing function, respiratory issues, and other factors should be addressed; signs of an undetected stricture may manifest with the conversion to table food
Radiologic assessment of the esophagus is required only if a significant history of choking, cyanosis, regurgitation, dysphagia, growth failure, coughing, or wheezing is noted. Subsequent endoscopic evaluation can be performed as indicated.
Follow-up care when the child is older can be performed as needed. Specific reassessment with esophageal endoscopy and biopsy when the patient is aged approximately 12 years has been advised by some who also advise follow-up with periodic endoscopy every few years until the patient is an adult. Although Barrett esophagus and subsequent malignant change have been described in this condition, presumably because of GER, it remains unclear whether endoscopic surveillance is necessary in patients with repaired esophageal atresia.[48, 49]
