Comparison of minimally invasive and open gastric transposition in children

Long-gap esophageal atresia: gastric transposition or esophageal lengthening with delayed primary anastomosis? A systematic review

PURPOSE

This study aims to evaluate different surgical approaches to long-gap esophageal atresia (LGEA) with or without tracheoesophageal fistula (TEF) is unclear.

METHODS

A systematic literature review was done comparing gastric transposition versus esophageal lengthening with delayed primary anastomosis in infants with LGEA+/-TEF. The primary outcome was time to full oral feeds. Secondary outcomes were time to full enteric feeds, need for further surgery, growth, mortality, and postoperative adverse events.

RESULTS

No comparative studies were found. However, the literature was re-interrogated for non-comparative studies. Four hundred thirty-eight articles were identified and screened, and 18 met the inclusion criteria. All were case series. Forty-three infants underwent gastric transposition, and 106 had esophageal lengthening with delayed primary anastomosis. One study on gastric transposition reported time to full oral feeds, and one study in each group reported growth. Time to full enteric feeds was reported in one study in each group. 30% of infants had further surgery following gastric transposition, including hiatus hernia repair (5/43, 12%) and esophageal dilation (7/43, 16%). Following esophageal lengthening, 62/106 (58%) had anti-reflux surgery, 58/106 (55%) esophageal dilatation and 11/106 (10%) esophageal stricture resection. Anastomotic complications occurred in 13/43 (30%), gastrointestinal in 16/43 (37%), respiratory in 17/43 (40%), and nerve injury in 2/43 (5%) of the gastric transposition group. In the esophageal lengthening group, anastomotic complications occurred in 68/106 (64%), gastrointestinal in 62/106 (58%), respiratory in 6/106 (6%), and none sustained nerve injury. Each group had one death due to a cause not directly related to the surgical procedure.

CONCLUSIONS

This systematic review highlights the morbidity associated with both surgical procedures and the variety in reporting outcomes.

Short and Medium Term Outcomes of Open and Laparoscopic Assisted Oesophageal Replacement Procedures

AIM OF THE STUDY

We describe the short- and medium-term outcomes following open and laparoscopic assisted oesophageal replacement surgery in a single tertiary paediatric surgical centre.

METHODS

A retrospective review (institutional audit approval no. 3213) on patients who underwent open or laparoscopic-assisted oesophageal replacement (OAR vs. LAR) at our centre between 2002 and 2021 was completed. Data collected (demographics, early complications, stricture formation, need for oesophageal dilatations, and mortality) were analysed using GraphPad Prism v 9.50 and are presented as median (IQR).

RESULTS

71 children (37 male) had oesophageal replacement surgery at a median age of 2.3 years (IQR 4.7 years). 51 were LAR (6 conversions). Replacement conduit was stomach (n = 67), colon (n = 3), or jejunum (n = 1). Most gastric transpositions had a pyloroplasty (46/67) or pyloromyotomy (14/67). Most common pathology was oesophageal atresia (n = 50 including 2 failed transpositions), caustic injury (n = 19 including 3 due to button battery), stricture of unknown cause (n = 1), and megaoesophagus (n = 1). There were 2 (2.8 %) early postoperative deaths at 2 days (major vessel thrombosis), 1 month (systemic sepsis), and one death at 5 years in the community. The rate of postoperative complications were comparable across LAR and OAR including anastomotic leak, pleural effusions, or early strictures. More patients with caustic pathology needed dilatations (60 % vs 30 % in OA, p = 0.05).

CONCLUSIONS

Outcomes of open and laparoscopic-assisted oesophageal replacement procedures are comparable in the short and medium term. Anastomotic stricture is higher in those with caustic injury.

Minimal access surgery of corrosive and thermal strictures of the foregut

Background and Aim

: Conventional surgery for caustic/thermal strictures (CS/TS) entails considerable trauma, which may be mitigated by minimal access surgery (MAS). Experience with its use in CS/TS is both heterogeneous and limited, hence, warrants a comprehensive review.

Methods

: Medical literature/indexing databases were systematically searched for pertinent articles published in English, from 1990 to 2021, and analysed.

Results

: Fifty relevant articles, pertaining to over 200 patients, were found. They showed that MAS is feasible in CS/TS management. It reduces the access damage in chest and abdomen whilst facilitating resection or bypass of the affected gut segment through different combination of operations, sequence of steps, conduits and routes. The procedures range from completely minimal access to hybrid ones, with reduced complications and faster recovery. Hybrid procedures prove as expeditious as open ones.

Conclusions

: MAS proves efficacious in restoring alimentary continuity in corrosive/thermal strictures of the foregut.

Functional outcome after laparoscopic assisted gastric transposition including pyloric dilatation in long-gap esophageal atresia

BACKGROUND/PURPOSE

Among the options for esophageal replacement in long-gap esophageal atresia (LGEA), gastric transposition (GT) is accessible for an endoscopic approach. Here we report a novel technique and functional results after laparoscopic-assisted gastric transposition (LAGT), including pyloric dilatation in patients with LGEA.

METHODS

Retrospective analysis of 14 children undergoing LAGT. Surgical steps included the release of the gastrostomy, transumbilical ante-situ section of the stomach including pyloric balloon-dilation, and laparoscopically controlled transhiatal retromediastinal blunt dissection followed by LAGT for cervical anastomosis to the proximal esophagus.

RESULTS

The median age at LAGT was 110 days (33-327 days), bodyweight 5.3 kg (3.1-8.3 kg). Operation time was 255 min (180-436 min); one conversion was necessary. The duration of ventilation was 4 days (1-14 days). Postpyloric feeding was started after 2 days, and oral feeding after 13 days. Complications were recurrent pleural effusion or pneumothorax and transient Horner syndrome or transient incomplete paresis of the recurrence nerve. After a median follow-up of 60 months (13-240 months), all children have a patent upper GI tract, show weight gain, and are fed without delayed gastric emptying, dumping, or reflux. Severe (n = 1) or mild (n = 2) anastomotic or pyloric (n = 5) stenosis was resolved with endoscopic dilatations.

CONCLUSIONS

Functional outcome after LAGT in patients with LGEA is good. The laparoscopic retromediastinal dissection preserves thoracal structures and increases patients' safety. The technique of pyloric dilatation might also prevent dumping syndrome.

Outcomes in adulthood of gastric transposition for complex and long gap esophageal atresia

BACKGROUND

Long term outcomes of gastric transposition (GT) for complex esophageal atresia (EA) are poorly reported. We aimed to perform comprehensive long term follow up of adults who had been treated with GT for EA as children.

METHODS

Consecutive patients who underwent GT for EA in childhood aged >18 years old were identified alongside age matched patients who had primary repair (PR). Type of EA, comorbidities and details of surgery were recorded. Telephone interviews included medical history, current symptoms - including gastrointestinal symptom rating scale (GSRS), morbidity and health related quality of life (HRQoL) using gastrointestinal quality of life index (GIQLI).

RESULTS

32 participants were interviewed in each group (mean age 29 years). BMI (19.9 ± 3.5) was significantly lower (p = 0.0006) in GT group. 6/32 (19%) still required supplementary feeding. Adult morbidity included anastomotic stricture (34%), chronic respiratory disease (28%), dumping symptoms (25%), anemia (47%) and depression (19%). 3 patients required major revision surgery. Participants in both groups report regular upper gastrointestinal symptoms (GSRS: GT = 2.1, PR = 2.0) and were more symptomatic than the normal population (1.4) but not statistically different from each other. HRQoL (GIQLI = 113) was lower than after PR (122) but not significantly different (p = 0.29) and the normal population (125). 23% of GT participants had higher than normal HRQoL.

CONCLUSIONS

GT for EA is associated with significant morbidity and symptoms, including issues previously unreported in adulthood such as mental health problems. This mandates long term follow up and quality transition of these patients into adult care.

Single-incision laparoscopy-assisted gastric transposition combined with thoracoscopic esophagectomy for esophageal replacement

INTRODUCTION

We present a novel approach to single-incision laparoscopy-assisted gastric transposition combined with thoracoscopic esophagectomy in a child with long-segment corrosive esophageal stricture (CES).

MATERIALS AND SURGICAL TECHNIQUE

A 2.5-year-old boy with a history of caustic ingestion underwent periodic esophageal dilatations at 3-week intervals, four sessions of topical mitomycin C application, and a strict antacid/H₂ antagonist therapy for 8 months. The esophageal replacement was indicated because of persistent corrosive esophageal stricture. First, thoracoscopic native esophagus dissection was performed. After gastric mobilization with single-incision laparoscopy, esophagectomy and esophagogastric anastomosis were performed through the cervical incision. There was no complication, and the patient had gained weight by the end of the 12-month follow-up.

DISCUSSION

Single-incision laparoscopy-assisted gastric transposition combined with thoracoscopic esophagectomy is feasible, safe, and effective in patients with corrosive esophageal stricture.

Management of long gap esophageal atresia: A systematic review and evidence-based guidelines from the APSA Outcomes and Evidence Based Practice Committee

BACKGROUND

Treatment of the neonate with long gap esophageal atresia (LGEA) is one of the most challenging scenarios facing pediatric surgeons today. Contributing to this challenge is the variability in case definition, multiple approaches to management, and heterogeneity of the reported outcomes. This necessitates a clear summary of existing evidence and delineation of treatment controversies.

METHODS

The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee drafted four consensus-based questions regarding LGEA. These questions concerned the definition and determination of LGEA, the optimal method of surgical management, expected long-term outcomes, and novel therapeutic techniques. A comprehensive search strategy was crafted and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized to identify, review and report salient articles.

RESULTS

More than 3000 publications were reviewed, with 178 influencing final recommendations. In total, 18 recommendations are provided, primarily based on level 4-5 evidence. These recommendations provide detailed descriptions of the definition of LGEA, treatment techniques, outcomes and future directions of research.

CONCLUSIONS

Evidence supporting best practices for LGEA is currently low quality. This review provides best recommendations based on a critical evaluation of the available literature. Based on the lack of strong evidence, prospective and comparative research is clearly needed.

TYPE OF STUDY

Treatment study, prognosis study and study of diagnostic test.

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.

Surgical techniques for esophageal replacement in children

PURPOSE

Surgical techniques for esophageal replacement (ER) in children include colon interposition, gastric tube, gastric transposition, and jejunal interposition. This review evaluates the merits and demerits of each.

METHOD

Surgical techniques, complications, and outcome of ER are reviewed over last seven decades.

RESULTS

Colon interposition is the time-tested procedure with minimal and less serious complications. Long-term complications include reflux, halitosis, colonic segment dilatation, and anastomotic stricture, sometimes requiring surgical interventions especially for dilatation and reflux. Gastric tube is technically more risky, and associated with early serious complications like prolonged leak in neck or mediastinum, graft necrosis, and ischemia leading to stricture of the tube. Long-term results are good. Gastric transposition is much simpler, can be performed in emergency and in newborns. It involves a single anastomosis in the neck. Post-operative complications include gastric stasis, bile reflux, restricted growth, and decreased pulmonary functional capacity. Jejunal interposition has not been used extensively due to short mesentery but long-term results are good in expert hands.

CONCLUSION

Colon is the most preferred and safest organ for ER. Stomach is a vascular and muscular organ with lower risk of ischemia. Gastric tube is a demanding technique. Jejunum or ileum is alternative for redo cases.

Esophageal replacement

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

Unusual postoperative complication of minimally invasive transhiatal esophagectomy and esophageal substitution for absolute dysphagia in a child with corrosive esophageal stricture

Esophageal substitution in children is a rare and challenging surgery. The minimally invasive approach for esophageal substitution is novel and reported from a few centers worldwide. While detailed report on the various complications of this approach has been discussed in adult literature, the pediatric experience is rather limited. We report the laparoscopic management of a rare complication which developed after laparoscopic esophagectomy and esophageal substitution. The timely recognition and management by the minimally invasive approach have been highlighted.

Preservation of native esophagus in infants with pure esophageal atresia has good long-term outcomes despite significant postoperative morbidity

PURPOSE

To evaluate long-term outcomes of pure esophageal atresia (EA) repair with preservation of native esophagus.

METHODS

Infants with pure EA treated at our institution (2000-2010) and with minimum 5-year follow-up were reviewed (REB:1000046653). Data analysed included demographics, management and outcomes and are reported as mean ± SD/median (range).

RESULTS

Of 185 infants with EA, 12 (7 %) had pure EA (gestational age: 36 ± 2.4 weeks, birth weight: 2353 ± 675 g). Ten had associated anomalies, including trisomy-21 (n = 2) and duodenal atresia (n = 1).

SURGERY

1 patient (short gap) underwent primary thoracoscopic anastomosis, 11 had gastrostomy (Stamm, n = 5; image-guided, n = 6) as initial procedure. At definitive repair (age: 128 ± 91 days; weight 5.5 ± 2.3 kg): ten had primary anastomosis and 1 had Collis gastroplasty. No patient had esophageal replacement surgery.

OUTCOMES

three patients had gastrostomy dehiscence requiring re-operation. At post-operative esophagram, seven had anastomotic leak successfully treated conservatively. Seven patients developed strictures requiring balloon dilatations (median two dilatations, range 1-10), six received antireflux surgery. At 7-year follow-up (range 5-15 years), all patients had the gastrostomy closed and were on full oral feeds.

CONCLUSIONS

The management of pure EA continues to be challenging. The preservation of native esophagus is possible with significant morbidity. The long-term outcomes are favourable.
