Total gastric transposition is better than partial gastric tube esophagoplasty for esophageal replacement in children

In a Setting of Esophageal Replacement, Total Gastric Pull-Up has Fewer Complications than Partial Gastric Pull-Up

AIM

The main indications for an esophageal replacement (ER) are unresolved complex esophageal atresia (EA) and caustic strictures (CS). The use of different organs for replacement has been described. When the stomach is chosen, there are two ways to do a gastric pull-up: a partial (PGP) or a total pull-up (TGP). Few studies have been published comparing the different techniques. The aim of this study was to compare the outcomes of patients who underwent ER by PGP or by TGT.

METHODS

The medical records of all patients who underwent gastric pull-up for ER in the last 18 years at the National Pediatric Hospital Prof. Dr. Juan P. Garrahan were reviewed. The study is comparative, retro-prospective and longitudinal. Patients were divided in two groups according to the ER technique (PGP or TGP). We compared the following outcomes: duration of the operation, days of hospitalization in the intensive care unit (ICU), days of total hospitalization, time to initiation of oral feedings and rate of anastomosis dehiscence, incidence of anastomotic stenosis, need for re-operations, incidence of gastroesophageal reflux disease (GERD), incidence of tracheo-esophageal fistulas (TEF), incidence of dumping syndrome, incidence of gastric necrosis and mortality.

RESULTS

There were 92 patients included in the study: 70 in the PGP group (76%) and 26 in the TGP group (24%). The two groups were demographically equivalent. Patients in the TGP group had a statistically significant lower incidence of anastomotic dehiscence (22,7% versus 54,3%; p = 0.01) and dumping syndrome (13,6% versus 37,1%; p = 0.038). Patients in the TGP had lower incidence of anastomotic stenosis, although the difference was not statistically significant. There were no statistically significant differences between the groups in terms of duration of the operation, postoperative days in the ICU, time to oral feedings, GERD, TEF or overall hospital stay. There were no cases of gastric necrosis. There were 3 deaths in the PGP group and one in the TGP group.

CONCLUSIONS

We observed benefits in the TGP group versus the PGP approach in terms of anastomotic dehiscence and dumping syndrome, as well as a trend toward a lower incidence of anastomotic stenosis. Based on this experience, we recommend the TGP approach for patients who need an esophageal replacement by a gastric pull-up.

Clinical outcome, quality of life, and mental health in long-gap esophageal atresia: comparison of gastric sleeve pull-up and delayed primary anastomosis

INTRODUCTION

Pediatric surgeons have yet to reach a consensus whether a gastric sleeve pull-up or delayed primary anastomosis for the treatment of esophageal atresia (EA), especially of the long-gap type (LGEA) should be performed. Thus, the aim of this study was to evaluate clinical outcome, quality of life (QoL), and mental health of patients with EA and their parents.

METHODS

Clinical outcomes of all children treated with EA from 2007 to 2021 were collected and parents of affected children were asked to participate in questionnaires regarding their Quality of Life (QoL) and their child's Health-Related Quality of Life (HRQoL), as well as mental health.

RESULTS

A total of 98 EA patients were included in the study. For analysis, the cohort was divided into two groups: (1) primary versus (2) secondary anastomosis, while the secondary anastomosis group was subdivided into (a) delayed primary anastomosis and (b) gastric sleeve pull-up and compared with each other. When comparing the secondary anastomosis group, significant differences were found between the delayed primary anastomosis and gastric sleeve pull-up group; the duration of anesthesia during anastomosis surgery (478.54 vs 328.82 min, p < 0.001), endoscopic dilatation rate (100% vs 69%, p = 0.03), cumulative time spent in intensive care (42.31 vs 94.75 days, p = 0.03) and the mortality rate (0% vs 31%, p = 0.03). HRQoL and mental health did not differ between any of the groups.

CONCLUSION

Delayed primary anastomosis or gastric sleeve pull-up appear to be similar in patients with long-gap esophageal atresia in many key aspects like leakage rate, strictures, re-fistula, tracheomalacia, recurrent infections, thrive or reflux. Moreover, HrQoL was comparable in patients with (a) gastric sleeve pull-up and (b) delayed primary anastomosis. Future studies should focus on the long-term results of either preservation or replacement of the esophagus in children.

Outcome of long gap esophageal atresia at 6 years: A prospective case control cohort study

BACKGROUND DATA

EA is the most frequent congenital esophageal malformation. Long gap EA remains a therapeutic challenge for pediatric surgeons. A case case-control prospective study from a multi-institutional national French data base was performed to assess the outcome, at age of 1 and 6 years, of long gap esophageal atresia (EA) compared with non-long gap EA/tracheo-esophageal fistula (TEF). The secondary aim was to assess whether initial treatment (delayed primary anastomosis of native esophagus vs. esophageal replacement) influenced mortality and morbidity at ages 1 and 6 years.

METHODS

A multicentric population-based prospective study was performed and included all patients who underwent EA surgery in France from January 1, 2008 to December 31, 2010. A comparative study was performed with non-long gap EA/TEF patients. Morbidity at birth, 1 year, and 6 years was assessed.

RESULTS

Thirty-one patients with long gap EA were compared with 62 non-long gap EA/TEF patients. At age 1 year, the long gap EA group had longer parenteral nutrition support and longer hospital stay and were significantly more likely to have complications both early post-operatively and before age 1 year compared with the non-long gap EA/TEF group. At 6 years, digestive complications were more frequent in long gap compared to non-long gap EA/TEF patients. Tracheomalacia was the only respiratory complication that differed between the groups. Spine deformation was less frequent in the long gap group. There were no differences between conservative and replacement groups at ages 1 and 6 years except feeding difficulties that were more common in the native esophagus group.

CONCLUSIONS

Long gap strongly influenced digestive morbidity at age 6 years.

Esophageal substitution or esophageal elongation procedures in patients with complicated esophageal atresia? Results of a comparative study

BACKGROUND

In newborns with complex esophageal atresia, there are situations in which a primary anastomosis cannot be safely performed. The alternative is performing a late anastomosis after the esophageal ends have gone through a period of spontaneous growth or after elongations of the distant ends of the esophagus and create an anastomosis under tension which causes risks of morbidity. An alternative to the elongation procedures is to perform a cervical esophagostomy with a gastrostomy for nutritional support and later on an esophageal replacement. The purposes of this retrospective chart review study are to report on our experience with esophageal substitution procedures in such cases, address the quality of life of a group of patients, and compare our results with those of patients who underwent esophageal elongation procedures as reported in the literature.

METHODS

Patients with esophageal atresia underwent esophageal replacement procedures and quality of life was assessed in a group of esophagocoloplasty patients.

RESULTS

From February 1978 to July 2019, 276 children (232 colonic interpositions and 44 total gastric transpositions) were studied; the most frequent complication was cervical anastomosis leakage [70 (30.2%) esophagocoloplasty patients and 7 (15.9%) gastric transposition patients], which sealed spontaneously in all but 4 patients. The quality of life was considered excellent or good in approximately 90% of the studied 70 out of the 276 patients; the comparison with the esophageal elongation procedures showed that esophageal substitution procedures promoted excellent long-term results with normal deglutition function (98.2% of patients, versus 33.3%, 36.5%, and 62.5%, respectively from the elongation series, P <0.0001 for all comparisons).

CONCLUSION

Esophagocoloplasty or total gastric transposition is a good alternative to treat patients with complex esophageal atresia.

Evaluation of Bilayer Silk Fibroin Grafts for Tubular Esophagoplasty in a Porcine Defect Model

Surgical reconstruction of tubular esophageal defects with autologous gastrointestinal segments is the gold standard treatment to replace damaged or diseased esophageal tissues. Unfortunately, this approach is associated with adverse complications, including dysphagia, donor-site morbidity, and in some cases patient death. Bilayer silk fibroin (BLSF) scaffolds were investigated as alternative, acellular grafts for tubular esophagoplasty in a porcine defect model for 3 months of implantation. Adult Yucatan mini-swine (n = 5) were subjected to esophageal reconstruction with tubular BLSF grafts (2 cm in length) in combination with transient esophageal stenting for 2 months followed by a 1-month period, where the graft site was unstented. All animals receiving BLSF grafts survived and were capable of solid food consumption, however strictures were noted at graft regions in 60% of the experimental cohort between 2 and 3 months postop and required balloon dilation. In addition, fluoroscopic analysis showed peristaltic function in only 1/5 neotissues. Following swine harvest at 3 months, ex vivo tissue bath evaluations revealed that neoconduits exhibited contractile responses to carbachol, electric field stimulation, and KCl, whereas sodium nitroprusside and isoproterenol induced relaxation effects. Histological (Masson's Trichrome) and immunohistochemical analyses of regenerated tissue conduits showed a stratified, squamous epithelium expressing pan-cytokeratins buttressed by a vascularized lamina propria containing a smooth muscle-rich muscularis mucosa surrounded by a muscularis externa. Neuronal density, characterized by the presence of synaptophysin-positive boutons, was significantly lower in neotissues in comparison to nonsurgical controls. BLSF scaffolds represent a promising platform for the repair of tubular esophageal defects, however improvements in scaffold design are needed to reduce the rate of complications and improve the extent of constructive tissue remodeling. Impact statement The search for a superior "off-the-shelf" scaffold capable of repairing tubularesophageal defects as well as overcoming limitations associated with conventional autologous gastrointestinal segments remains elusive. The purpose of this study was to investigate the performance of an acellular, bilayer silk fibroin graft (BLSF) for tubular esophagoplasty in a porcine model. Our results demonstrated that BLSF scaffolds supported the formation of tubular neotissues with innervated, vascularized epithelial and muscular components capable of contractile and relaxation responses. BLSF scaffolds represent a promising platform for esophageal tissue engineering.

Prospective evaluation of clinical outcomes and quality of life after gastric tube interposition as esophageal reconstruction in children

Few studies on gastric tube interposition for esophageal reconstruction in children have assessed the long-term outcomes and quality of life (QoL). The aim of this study is to evaluate the long-term outcomes and QoL after a gastric tube interposition by reviewing our experiences with esophageal reconstruction.Twenty-six patients were included who underwent gastric tube interposition from 1996 to 2011 at our institution. We reviewed the medical records and conducted telephone surveys, prospectively performed esophagography, endoscopy, 24-hour pH monitoring, and esophageal manometry. The median follow-up period of 12 (range, 3-18) years.Median age at the time of surgery and survey were 9 (range, 2-50) months and 12.4 (range, 3.1-19.0) years, respectively. There were 14 cases of reoperation of gross type C and B esophageal atresia (EA) and 10 cases of long gap pure EA. The z scores of anthropometric data at the survey did not increase after the operation. Severe stricture in esophagography was observed in 20% of patients, but improved with balloon dilation with intact passage. Gastroesophageal reflux was able to be treated with medications. Esophageal peristalsis was observed in 1 of 8 patients in manometry. No Barrett esophagus or metaplasia was not found from endoscopy. QoL was similar to the general population and did not differ between age groups.Gastric tube interposition could be considered for esophageal reconstruction in pediatric patients when native esophageal anastomosis is impossible. Nutritional evaluation and support with consecutive radiological evaluation to assess the anastomosis site stricture are advised.

Oesophageal replacement with stomach: A personal series and review of published experience

AIM

To describe the outcomes of oesophageal replacement using stomach in children.

METHODS

All children undergoing oesophageal replacement in a regional centre were prospectively recorded in a customised database and subjected to continual follow up. Complications within 30 days were classified as early, and all other complications were classified as late. Outcomes were related to a comprehensive analysis of published experience where studies were classified as having long-term follow up if the median duration exceeded 5 years.

RESULTS

Ten children underwent oesophageal replacement using the stomach between 1998 and 2016. Indications were oesophageal atresia (6), caustic ingestion (2), foreign body ingestion (1) and oesophageal hamartoma (1). Two children died at 2 and 7 months after gastric transposition. All survivors are under review, with a median follow up of 8.5 years (range 3-14 years). Complications occurred in every case. Among survivors, three had early complications and eight had late complications. Early complications included anastomotic leak (2) and lung compression by stomach (1). Late complications were anaemia (8), anastomotic stricture (7), oesophagitis (5), dumping syndrome (2), perforation of a jejunostomy (1), para-gastric hiatal hernia (1), gastric outlet obstruction (1), Barrett's oesophagus (1), prolonged inability to swallow (1) and recurrent lower respiratory tract infections (1). Among 57 publications, only three achieved complete long-term follow up. The incidence of reported complications was higher when follow up was complete.

CONCLUSIONS

Oesophageal replacement by gastric transposition in children leads to serious chronic morbidity. Published experience masks this because of incomplete and short follow up.

Outcomes of primary gastric transposition for long-gap esophageal atresia in neonates

BACKGROUND

Gastric transposition is a relatively novel method of esophageal replacement. The purpose of this retrospective study was to assess the outcomes of long-gap esophageal atresia (LGEA) treated with esophageal replacement using primary gastric transposition in neonates.

METHODS

Between March 2008 and May 2015, 14 newborns with LGEA were treated in our hospital. They were all found to have gaps of over 3 cm at the time of the surgery and were diagnosed with LGEA. Primary gastric transposition was performed. They also underwent a gastric drainage procedure by pyloromyotomy. The nasogastric tube was removed if no anastomotic fistula was present and oral feeding was initiated. After initial recovery and discharge, the patients were evaluated with outpatient follow-ups or telephone follow-ups from 1 month after the surgery.

RESULTS

The mean age of the neonates at the time of the surgery was 32 hours (range, 4-96 h). The mean birth weight was 2550 g (range, 2100-3500 g). There were 2 deaths in this series of patients due to respiratory failure or withdrawal of treatment by the parents, with a mortality rate of 14.3%. Seven of the neonates developed unilateral or bilateral severe pneumonia. Early anastomotic leak occurred in 3 cases and anastomotic strictures occurred in 4 cases. These 4 neonates were able to eat a fairly normal diet after esophageal balloon dilation. Gastroesophageal reflux occurred in 7 of 12 cases. Feeding multiple small meals and postural support for positioning and feeding were instructed for these 7 cases. Subsequently, the symptoms alleviated and they had no additional surgical therapy. None of the neonates had delayed gastric emptying or gastric retention.

CONCLUSION

Primary gastric transposition may be a rewarding reconstructive option in the treatment of LGEA.

Surgical outcomes of different approaches to esophageal replacement in long-gap esophageal atresia: A systematic review

BACKGROUND

Esophageal replacement (ER) surgery has been widely used in long-gap esophageal atresia (LGEA) over the past few decades. The most commonly used surgical approaches in many pediatric surgical centers include colon interposition (CI), gastric pull-up (GPU), jejunal interposition (JI), and gastric tube reconstruction (GTR). However, there is no systematic evidence on which is the optimal conduit for the native esophagus. The aim of this systematic review was to evaluate the short- and long-term outcomes among these 4 replacement approaches in LGEA cases based on current evidence.

METHODS

PubMed, Web of Science, Cochrane Library, and EMBASE were searched for relevant literature on November 18 2016. Studies on ER in LGEA were reviewed and selected according to eligibility criteria. We focused on surgical outcomes regarding to different replacement approaches, including postoperative complications and long-term follow-up. Both detailed descriptions of single studies and pooled data analysis were conducted. Data were computed by Reviewer Manager 5.3.

RESULTS

Twenty-three studies were included (4 comparative retrospective, 3 prospective, and 16 retrospective) with a total of 593 patients (393 LGEA, 66.3%). The number of patients with available data for analysis was 534 (90.1%), including 127 patients (98 LGEA) of GPU, 335 (223 LGEA) of CI, 45 (all LGEA) of JI, and 27 (all LGEA) of GTR. Follow-up information was provided in 15 studies. Anastomotic leak and stricture, respiratory problems, and gastroesophageal reflux were analyzed as major postoperative complications. Long-term follow-ups were concentrated on growth and feeding conditions.

CONCLUSION

Current evidence on short- and long-term outcomes of ER in LGEA patients was limited, and proper prospective comparative studies were lacking. This present systematic review indicates CI and GPU as comparable and favorable approaches, especially CI in the long-term outcomes. Studies on JI and GTR were limited, which need larger sample size to assess their validity and outcomes.

Decellularized material as scaffolds for tissue engineering studies in long gap esophageal atresia

INTRODUCTION

Esophageal atresia refers to an anomaly in foetal development in which the esophagus terminates in a blind end. Whilst surgical correction is achievable in most patients, when a long gap is present it still represents a major challenge associated with higher morbidity and mortality. In this context, tissue engineering could represent a successful alternative to restore oesophageal function and structure. Naturally derived biomaterials made of decellularized tissues retain native extracellular matrix architecture and composition, providing a suitable bed for the anchorage and growth of relevant cell types. Areas covered: This review outlines the various strategies and challenges in esophageal tissue engineering, highlighting the evolution of ideas in the development of decellularized scaffolds for clinical use. It explores the interplay between clinical needs, ethical dilemmas, and manufacturing challenges in the development of a tissue engineered decellularized scaffold for oesophageal atresia. Expert opinion: Current progress on oesophageal tissue engineering has enabled effective repair of patch defects, whilst the development of a full circumferential construct remains a challenge. Despite the different approaches available and the improvements achieved, a gold standard for fully functional tissue engineered oesophageal constructs has not been defined yet.

Partial gastric pull-up in the treatment of patients with long-gap esophageal atresia

BACKGROUND

This study was to analyze outcomes of long-gap esophageal atresia (LGEA) treated with partial gastric pull-up (PGP) into the thorax.

METHODS

The medical records of all children who had undergone PGP for LGEA from 1999 to 2012 were reviewed. Preoperative data, initial postoperative course, complications, time to full oral nutrition, follow-up diagnostics and nutritional status were assessed.

RESULTS

Nine children who had undergone PGP were followed up for a mean period of 6.2 ± 3.1 years. Their median gestational age was 37 ± 2 weeks, and mean birth weight 2462 ± 658 g. Eight children were primarily treated with a gastrostomy, their mean age at PGP was 11.4 ± 10.9 weeks and mean weight was 4484 ± 1966 g. Their mean operation time was 199 ± 51 minutes. Leakage was an early postoperative complication in three children, one of whom had a consecutive stricture resection. Late complications were stenosis (n=7) and gastro-esophageal reflux (n=5). The general status of the children was judged as "good" or "very good" on the last presentation. The median percentile of the body-mass-index was 25. Gastroscopy at 3.7 ± 3.2 years after the operation revealed a grade I esophagitis in two children. There was no death in this group of children.

CONCLUSIONS

Because of its high complication rate, partial gastric pull-up cannot be recommended as an alternative for the treatment of LGEA at present. A final judgment could be made on the basis of a comparative study.

Surgical treatment of esophagogastric dysfunction forty years after reverse gastric tube esophagoplasty for congenital esophageal anomaly

BACKGROUND

In 1968, Burrington first described use of the reverse gastric tube esophagoplasty for esophageal replacement in children with esophageal atresia or acquired stenosis. There are few documented cases of long-term follow-up of these patients.

CASE REPORT

We describe a 41-year-old female who presented with progressive dysphagia 40 years after reverse gastric tube for a congenital esophageal stenosis as an infant. Repeated endoscopic dilations were unsuccessful in relieving her symptoms, and she subsequently underwent a modified Ivor-Lewis esophagogastrectomy with resection of the reverse gastric tube and reconstruction using her remaining gastric remnant.

CONCLUSIONS

This report describes what we believe to be the longest recorded follow-up after reverse gastric tube esophagoplasty and highlights the potential for long-term complications after surgery for congenital anomalies.

Should patients with esophageal atresia be submitted to esophageal substitution before they start walking?

Esophagocoloplasty and gastric transposition are two major methods for esophageal substitution in children with esophageal atresia, and there is broad agreement that these operations should not be performed before the children start walking. However, there are some reported advantages of performing such operations in the first months of life or in the neonatal period. In this study, we compared our experience with esophageal substitution procedures performed in walking children with esophageal atresia, with the outcomes of children who had the operation before the third month of life reported in the literature. The purpose of this study was to establish if we have to wait until the children start walking before indicating the esophageal replacement procedure. From February 1978 to October 2009, 129 children with esophageal atresia underwent esophageal replacement in our hospital (99 colonic interpositions and 30 gastric transpositions). The records of these patients were reviewed for data regarding demographics, complications (leaks, graft failures, strictures, and graft torsion), and mortality and compared with those reported in the two main articles on esophageal replacement in the neonatal period or in patients less than 3 months of age. The main complication of our casuistic was cervical anastomosis leakage, which sealed spontaneously in all except in four patients. One patient of the esophagocoloplasty group developed graft necrosis and three patients in the gastric transposition group had gastric outlet obstruction, secondary to axial torsion of the stomach placed in the retrosternal space. The long-term outcome of the patients in both groups was considered good to excellent in terms of normal weight gain, absence of dysphagia, and other gastrointestinal symptoms. The comparisons of the main complications and mortality rates in walking children with esophageal substitutions performed in the first months of life showed that the incidences of cervical anastomotic leaks and graft failures were similar, but mortality rate in the first few months of life was significantly greater than that observed in our group of patients (P= 0.001). Based on the comparison of our results with those of published series, we conclude that the recommendation of performing esophagocoloplasty or total gastric transposition in children with esophageal atresia after they start walking is still valid.

Effect of esophagoplasty on the mucosa structure in the gastric transplant

Structural modifications of the gastric tube transplant were studied during the delayed period after esophagoplasty carried out for benign diseases of the esophagus. Adaptive and pathological reactions manifesting in atrophic and sclerotic changes in the mucosa formed the basis for transplant reorganization. The leading morphological markers were degeneration and hypersecretion of the foveolar epithelium, focal atrophy of the fundal glands with foci of pyloric metaplasia, hypertrophy and fibrosis of the muscle plate, and stromal sclerosis. Abundant polymorphonuclear infiltration of the mucosa with lymphoid follicular hyperplasia were observed in H. pylori contamination of the gastric transplant.

Colonic interposition for esophageal replacement in children remains a good choice: 33-year median follow-up of 65 patients

INTRODUCTION

Gastric pull-up has become the predominant technique for esophageal replacement because of allegedly deficient results of colon grafts. This retrospective study examines the long-term results in a large series of colonic interpositions.

PATIENTS AND METHOD

One hundred six children (median, 2.9 years; range, 0.32-15 years) had their esophagus replaced between 1965 and 2008, of which 96 had colon grafts. Those survivors who were 18 years and older were contacted and, if willing, interviewed, examined, and had their functional ability rated using the Karnofsky index.

RESULTS

Ninety-six children had undergone a colon graft, and of these, 9 (9.3%) died. There were 65 long-term survivors whose indications for surgery included caustic injury (n = 32), failed tracheoesophageal fistula repair (n = 16), pure esophageal atresia (n = 14), and others (n = 3). The graft was either retrosternal (n = 49) or mediastinal (n = 16 patients). Twelve patients were unavailable for long-term assessment. After a median follow-up of 33.3 (11-41) years, 23 (43%) of 53 individuals experienced mild symptoms of reflux; scoliosis, 12 (22%) of 53, and/or other complications, 15 (27%) of 53 required further surgery. Thirty-two patients (60%) with Karnofsky indexes of 80% or higher felt healthy, 19 (36%) had mild life-style limitations (index, 40%-80%), and 2 had indexes less than 40%. Most patients live normal lives.

CONCLUSIONS

Colon conduits restored gastrointestinal continuity with limited mortality and considerable morbidity but good functional outcome and health perception in the long-term. Our study suggests that colon grafts are no worse than gastric pull-ups in the long-term.

Repair of long-gap esophageal atresia: gastric conduits may improve outcome—a 20-year single center experience

INTRODUCTION

Treatment of long-gap esophageal atresia (LEA) is a major challenge. Options for reconstruction include native esophagus, or replacement with stomach, colon, or small intestine. However, debate continues regarding the optimal conduit for esophageal replacement.

METHODS

Medical records of patients with a diagnosis of esophageal atresia during a 20-year period were reviewed.

RESULTS

Twenty-eight cases of LEA were identified. Ten patients underwent primary anastomosis either after serial pouch dilations (9/10) and/or after a lengthening procedure (2/10). Nine received colonic interpositions, and the remainder were reconstructed with a gastric tube (n = 3), or gastric interposition (n = 2). One patient died prior to repair, and two await definitive treatment. Repeat esophageal reconstruction was required in four patients because of conduit ischemia. Two ischemic events occurred in the colonic interposition group, and two in the native esophageal repairs. All patients, except one who relocated, received long-term follow-up (mean 4.2 years: range 0.5-11.5 years).

CONCLUSIONS

Surgeon's expertise and patient's anatomy should be considered when selecting an appropriate operation for LEA. Although native esophagus is generally preferred, it is associated with a high rate of stricture. Although our study has a limited by numbers, we found that patients with gastric conduits had lower complication rates and no conduit ischemia. We suggest that gastric transposition may be favored as an initial reconstructive option.

Esophageal atresia repair with thoracotomy: the Cincinnati contemporary experience

Esophageal atresia/tracheoesophageal fistula (EA/TEF) repair using an open muscle-sparing thoracotomy has been the standard approach used in our institution. Whereas perioperative mortality is now very uncommon, short- and long-term morbidity is very common in these patients. However, the complexity of the esophageal anatomy and significant comorbidities appear to be important contributors to significant complications in these patients. At least 30% of the EA/TEF patients required esophageal dilatations for anastomotic stricture; this increased to 50% for patients with pure EA. Gastroesophageal reflux requiring an antireflux procedure was performed 23% of the time for EA/TEF and 30% for EA patients. In addition, there were a few complications, such as winging of the scapula and scoliosis, that were attributed in part to the utilization of a nonmuscle-sparing thoracotomy. The standard muscle-sparing thoracotomy remains a very versatile and useful approach to repairing esophageal atresia, and it is the standard for repairing more complex anatomical variants. The self-reported long-term quality of life in these patients is very good, except for a few individuals with protracted feeding disorders and severe dysphagia.

Esophageal atresia: the total care in a high-risk population

The outcome of cases of esophageal atresia depends on many factors that affect the prognosis. These factors have been identified since Waterston aimed to classify the anomaly according to the risk factors. There are other factors that affect the outcome, and these differ in different parts of the globe. This comprehensive review attempts to incorporate all the factors--preoperative, operative, and postoperative--that can pose risks to the ultimate survival of the baby. Early detection for proper management of these cases is essential. Feasibility to perform early esophageal replacement has come as a boom for these high-risk cases. Total care in a high-risk population of esophageal atresia depends on the investigative modalities adopted, available neonatal ICU care, and the surgeon's experience. An attempt continues to decrease the associated morbidity and mortality in high-risk babies born with esophageal atresia and tracheoesophageal fistula.
