Use of a report card to evaluate outcomes of achalasia surgery: beyond the Eckardt score

Achalasia: laparoscopic Heller myotomy with fundoplication versus peroral endoscopic myotomy-a systematic review and meta-analysis

There are various therapeutic options for achalasia. Nevertheless, peroral endoscopic myotomy (POEM) and laparoscopic Heller myotomy with fundoplication (LHM) are distinguished by their efficacy and low incidence of complications. Compare POEM and LHM regarding several outcomes in patients with achalasia. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An exhaustive literature search was performed using PubMed, Web of Science, and Cochrane Library databases. Studies comparing several outcomes between POEM and LHM in patients with achalasia were included. Data on clinical success, operative time, intraoperative complications, length of stay, reintervention rates, postoperative pain, overall complications, occurrence of GERD symptoms, use of proton bomb inhibitors and esophagitis were extracted. Quality assessment of the included studies was performed using the MINORS scale. We included 20 retrospective observational studies with a combined total of 5139 participants. The results demonstrated that there was no statistically significant difference in terms of intraoperative complications, postoperative complications, reintervention rate, occurrence of GERD symptoms, GERD HRQL, use of proton pump inhibitors, and esophagitis between POEM and LHM groups. Conversely, POEM was associated with higher clinical success and shorter operative time, length of stay, and postoperative pain. This meta-analysis concludes that both POEM and LHM, are effective and safe treatments for achalasia. However, POEM demonstrates better results regarding clinical success, operative time, length of stay, postoperative pain, and a tendency towards lower recurrence.

Comparing clinical outcomes of peroral endoscopic myotomy for achalasia between Eastern and Western countries: a systematic review and meta-analysis

Peroral endoscopic myotomy (POEM) has revolutionized the therapeutic strategy for achalasia with promising results. We conducted this meta-analysis to compare clinical outcomes between Eastern and Western countries. A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science and Cochrane Library databases to query for studies that assessed the efficacy of POEM for achalasia. All articles published from inception to December 31, 2021 were included. The primary outcome was the pooled clinical success rate. The secondary outcomes included the pooled technical success rate, incidence of adverse events, procedure time and hospital stay. Eighteen Eastern studies involving 5962 patients and 11 Western studies involving 1651 patients were included. The pooled clinical success rate and technical success rate for POEM was equal in the Eastern studies compared to Western studies. The pooled incidence of procedure adverse events for POEM was a little lower in the Eastern studies compared to Western studies (6.6% vs. 8.7%). Similarly, the incidence of reflux-related adverse events was lower in Eastern studies than that in Western studies. The pooled procedure time of POEM was shorter in Eastern studies compared to Western studies (61 minutes vs. 80 minutes), while the length of hospital stay was longer in Eastern studies compared to Western studies (5.8 days vs. 2.4 days). Overall, Eastern countries have the similar POEM outcomes compared to Western countries. However, Eastern countries still need to do more to reduce the length of hospital stay.

Using impedance planimetry to define the end of a peroral endoscopic myotomy

INTRODUCTION

Peroral endoscopic myotomy (POEM) is a minimally invasive endoscopic option for management of achalasia. Adequate distal myotomy is necessary for relief of symptoms, but when too long may also increase risk of reflux. The objective of this study is to evaluate clinical outcomes after POEM and final length of gastric myotomy using impedance planimetry (EndoFLIP).

METHODS

A retrospective review of 34 consecutive patients undergoing POEM with EndoFLIP were included. EndoFLIP measurements, including esophagogastric junction distensibility index (DI), minimum diameter (Dmin), and cross-sectional area (CSA) were recorded at 30- and 40-mL balloon-fill pre- and post- myotomy. The myotomy was considered complete when DI ≥ 3.4 mm2/mmHg. Postoperative Eckardt score (ES) was determined at initial postoperative visit and most recent follow-up. Linear and logistic regression were used to evaluate the association between gastric myotomy length and post-myotomy EndoFLIP measurements on postoperative ES and GERD. Wilcoxon rank-sum test was used to compare gastric myotomy lengths and EndoFLIP parameters in relation to clinical success and development of GERD, and paired t-test to compare EndoFLIP measurements and ES pre- and post-myotomy.

RESULTS

Final length of gastric myotomy measured 1 cm in 1 (2.9%), 1.5 cm in 11 (32.4%), 2.0 cm in 19 (55.9%), and 2.5 cm in 3 (8.8%) patients. Mean preoperative ES was 6.6 ± 2.2. All patients achieved ES < 3 postoperatively, which was maintained in 88.5% of patients at a median of 7.5 months of follow-up. Gastric myotomy length and post-myotomy EndoFLIP values were not associated with postoperative Eckardt scores or GERD.

DISCUSSION

Early and late symptom relief was achieved in 100 and 88.5% of patients, respectively, at a gastric myotomy length of 1-2.5 cm. Using EndoFLIP to define a completed myotomy at DI of 3.4 mm2/mmHg yielded variable lengths of gastric myotomy.

MANAGEMENT OF SYMPTOMS RECURRENCE AFTER MYOTOMY FOR ACHALASIA. A PRACTICAL APPROACH

BACKGROUND

Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases.

AIMS

This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy.

METHODS

A critical review was performed to gather evidence for a rational approach for managing the recurrence or persistence of achalasia symptoms after myotomy.

RESULTS

To properly manage an achalasia patient with significant symptoms after myotomy, such as dysphagia, regurgitation, thoracic pain, and weight loss, it is necessary to classify symptoms, stratify severity, perform appropriate tests, and define a treatment strategy. A systematic differential diagnosis workup is essential to cover the main etiologies of symptoms recurrence or persistence after myotomy. Upper digestive endoscopy and dynamic digital radiography are the main tests that can be applied for investigation. The treatment options include endoscopic dilation, peroral endoscopic myotomy, redo surgery, and esophagectomy, and the decision should be based on the patient's individual characteristics.

CONCLUSIONS

A good clinical evaluation and the use of proper tests jointly with a rational assessment, are essential for the management of symptoms recurrence or persistence after achalasia myotomy.

Mucosal injury during laparoscopic Heller cardiomyotomy: risk factors and impact on surgical outcomes

PURPOSE

To investigate the risk factors and outcomes of mucosal perforation (MP) during laparoscopic Heller myotomy (LHM) in patients with achalasia.

METHODS

We conducted a retrospective analysis of patients who underwent LHM for achalasia at a single facility.

RESULTS

Among 412 patients who underwent LHM for achalasia, MP was identified in 52 (12.6%). Old age, long disease duration, low albumin level, an esophageal transverse diameter  > 6 cm, and a sigmoid-shaped esophagus were found to be independent predictors of MP. These factors were assigned a pre-operative score to predict the perforation risk. MP had a significant impact on intra and post-operative outcomes. Gastric side perforation was associated with a higher incidence of reflux symptoms, whereas esophageal-side perforation had a higher incidence of residual dysphagia.

CONCLUSIONS

Many risk factors for MP have been identified. Correctable parameters like low serum albumin should be resolved prior to surgery, while uncorrectable parameters like old age and a sigmoid-shaped esophagus should be managed by experienced surgeons in high-volume centers. Implementing these recommendations will help decrease the incidence and consequences of this serious complication.

Impact of peroral endoscopic myotomy on high-resolution manometry findings and their association with the procedure's outcomes

BACKGROUND AND AIMS

Peroral endoscopic myotomy (POEM) is conducted for patients with esophageal motility disorders based on high-resolution manometry (HRM) findings. However, the impact of POEM on HRM findings and the associations between post-POEM HRM and outcomes have not been clarified.

METHODS

In a multicenter, observational, cohort study, patients with achalasia treated by POEM received follow-up HRM. Associations between patient characteristics, POEM procedures, and post-POEM HRM findings, including integrated relaxation pressure (IRP) and distal contractile integral (DCI), were investigated. Furthermore, POEM procedure outcomes were compared with post-POEM HRM findings.

RESULTS

Of 2171 patients, 151 (7.0%) showed residual high post-POEM IRP (≥26 mm Hg; Starlet [Starmedical Ltd, Tokyo, Japan]). In a multivariate analysis, high pre-POEM IRPs (odds ratio [OR], 24.3) and gastric myotomy >2 cm (OR, .22) were found to be positive and negative predictive factors of high post-POEM IRPs, respectively. Peristalsis recovery (DCI ≥500 mm Hg/cm/s, at least 1 swallow; Starlet) was visible in 121 of 618 patients (19.6%) who had type II to III achalasia. High pre-POEM IRP (OR, 2.65) and DCI ≥500 (OR, 2.98) predicted peristalsis recovery, whereas esophageal dilation (OR, .42) predicted a risk of no recovery. Extended myotomy did not reveal a significant impact on peristalsis recovery. High or low post-POEM IRP and DCI did not increase the incidence of clinical failure, reflux esophagitis, or symptomatic GERD.

CONCLUSIONS

Extended gastric myotomy decreased IRP values, whereas peristalsis recovery depended on the characteristics of achalasia. A residual high post-POEM IRP does not necessarily mean clinical failure. Routine HRM follow-up is not recommended after POEM.

Mid-Term and Long-Term Outcomes of Peroral Endoscopic Myotomy for the Treatment of Achalasia: A Systematic Review and Meta-Analysis

BACKGROUND AND AIMS

Peroral endoscopic myotomy (POEM) achieves a satisfactory short-term clinical response in patients with achalasia. However, data on mid- and long-term clinical outcomes are limited. We aimed to assess the mid- and long-term efficacy and safety of POEM in achalasia patients.

METHODS

Using the pre-designed search strategy, we identified relevant studies that evaluated the efficacy and safety of POEM with a minimum of 2-year follow-up in the Embase, Cochrane, and PubMed databases from inception to January 2021. Primary outcome was pooled mid- and long-term clinical success rate based on the Eckardt score. Secondary outcome was pooled long-term reflux-related adverse events.

RESULTS

A total of 21 studies involving 2,698 patients were included. Overall, the pooled clinical success rates with 2-, 3-, 4-, and 5-year follow-ups were 91.3% (95% confidence interval [CI] 88.4-93.6%), 90.4% (95% CI 88.1-92.2%), 89.8% (95% CI 83.6-93.9%), and 82.2% (95% CI 76.6-86.7%), respectively. Besides, the pooled long-term clinical success rates for type I, II, and III achalasia were 86.1% (95% CI 80.9-90.1%; I2 = 0%), 87.9% (95% CI 84.2-90.8%; I2 = 48.354%), and 83.9% (95% CI 72.5-91.2%; I2 = 0%), respectively. Moreover, the pooled incidence of symptomatic reflux and reflux esophagitis was 23.9% (95% CI 18.7-29.9%) and 16.7% (95% CI 11.9-23.1%), respectively.

CONCLUSIONS

POEM is associated with a long-term clinical success of 82.2% after 5 years of follow-up. Randomized control trials comparing POEM with laparoscopic Heller myotomy or pneumatic dilation with longer follow-up periods are needed to further demonstrate the long-term safety and efficacy of POEM.

Peroral endoscopic myotomy for the treatment of achalasia in the Unified Healthcare System (SUS): results of a short-term

INTRODUCTION

achalasia is a chronic disease. Since there is no curative treatment, diagnosed patients have pharmacological and/or surgical techniques available, aimed at minimizing the condition. POEM appears as a promising new type of palliative treatment with good rates of symptom improvement.

OBJECTIVE

evaluate the profile of POEM at the Clinical Hospital of the Federal University of Pernambuco (HC - UFPE) and correlate it with the world scenario.

METHODS

data collection was performed retrospectively from September 2017 to October 2019 with all patients undergoing POEM at the HC - UFPE. Sociodemographic, clinical, and hospital variables were evaluated before and three months after the procedure.

RESULTS

of 27 patients (52.41 ± 19.24 years old) who underwent the procedure, 66.7% had idiopathic etiology and 33.3% had etiology secondary to Chagas disease. 48% patients underwent previous procedures, of which seven used some type of medication for symptom control, two underwent pneumatic endoscopic dilation, and four underwent Heller cardiomyotomy with partial fundoplication. 62.5% of the evaluated patients had type II achalasia before the procedure. Seven (25.9%) patients presented the following adverse events: four presented bleeding, two pneumoperitoneum, and one both complications, all being treated conservatively. The Eckardt score reduced from 8.37 ± 1.45 to 0.85 ± 1.06 (p-value <0.001).

CONCLUSION

clinical improvement of symptoms and the patient profile followed the worldwide trend, with emphasis on the etiology secondary to Chagas disease, endemic in Brazil. Gastroesophageal reflux remains the main post-operative symptom.

Quality of life in patients with achalasia: Associations with Eckardt score and objective treatment outcomes after peroral endoscopic myotomy

Background and study aims  Knowledge on self-reported quality of life (QoL) in achalasia and QoL improvements after peroral endoscopic myotomy (POEM) is limited. Furthermore, the clinical role of QoL in achalasia follow-up has not been evaluated. The present study aimed to examine QoL in achalasia patients before and after POEM and assess associations between QoL, Eckardt score (ES) and objective results. Patients and methods  This was a single-center prospective study of treatment-naïve achalasia patients with 12-month follow-up after POEM including manometry, upper endoscopy, 24-hour pH registration, and timed barium esophagogram. QoL data were registered using European Organisation for Research and Treatment of Cancer core questionnaire (QLQ-C30) and esophageal module (QLQ-OES18). Comparison with a reference population was performed to assess impact of achalasia on QoL and effect of therapy. Mixed models for repeated measures were applied. Results  Fifty patients (26 females) with a median age of 47 years (18-76) were included. Before treatment, all QoL domains were significantly impaired compared with an age- and gender-adjusted reference population ( P  < 0.05). No significant QoL-differences were found after POEM, except for fatigue and nausea/vomiting. Clinically relevant QoL improvement was observed in ≥ 50 % of the patients in all QoL domains, except for physical and role functioning. QoL was significantly associated with ES ( P  < 0.05) but not with objective results. Conclusions  Achalasia is associated with severe QoL impairment. Following POEM, a significant and clinically relevant QoL improvement is observed. QoL is associated with ES, but not with objective results after POEM.

Comparative Analysis of Heller Myotomy With Dor Versus Toupet Fundoplication for Achalasia Cardia

Background Heller myotomy (HM) with partial fundoplication is the standard of care for achalasia cardia. However, the choice of partial fundoplication is controversial. In this study, we compared both types of fundoplication concerning subjective and objective parameters. Methodology This prospective comparative study comprised a total of 30 consecutive patients who underwent laparoscopic/robotic HM with either Dor fundoplication (DF) (n = 15) or Toupet fundoplication (TF) (n = 15). Preoperative baseline characteristics, intraoperative details, and postoperative complications were recorded. Patients were followed with Eckardt score, quality of life-related scores, 24-hour pH study, and high-resolution manometry (HRM) at the one-year follow-up. Results There was no significant difference between the two groups regarding preoperative baseline parameters, length of hospital stay, and postoperative complications. The HM+DF group had four (27%) patients with recurrence/failure with none in the HM+TF, but it was not significant (p = 0.79). Symptom scores were similar between the groups at six and 12 months of follow-up. One patient in the HM+DF group and two in the HM+TF group had significant pathological acid reflux (p = 0.483). On HRM, HM+TF showed a trend toward significance in terms of esophagogastric junction (EGJ) relaxation (p = 0.058) with a non-significant difference in median integrated relaxation pressure (p = 0.081). Conclusions The study showed a trend toward lower failure rates and improved EGJ relaxation with similar reflux rates in patients who underwent HM+TF compared to HM+DF. However, long-term follow-up is required to validate our findings with well-defined subjective and objective criteria.

Esophageal Achalasia: From Laparoscopic to Robotic Heller Myotomy and Dor Fundoplication

Objective:

Laparoscopic Heller myotomy and Dor fundoplication has become the gold standard in treating esophageal achalasia and robotic surgical platform represents its natural evolution. The objective of our study was to assess durable long-term clinical outcomes in our cohort.

Methods and Procedures:

Between June 1, 1999 and June 30, 2019, 111 patients underwent minimally invasive treatment for achalasia (96 laparoscopically and 15 robotically). Fifty-two were males. Mean age was 49 years (20 – 96). Esophageal manometry confirmed the diagnosis. Fifty patients underwent pH monitoring study, with pathologic reflux in 18. Preoperative esophageal dilation was performed in 76 patients and 21 patients received botulin injection. Dysphagia was universally present, and mean duration was 96 months (5 – 480).

Results:

Median operative time was 144 minutes (90 – 200). One patient required conversion to open approach. Four mucosal perforations occurred in the laparoscopic group and were repaired intraoperatively. Seven patients underwent completion esophageal myotomy and added Dor fundoplication. Upper gastrointestinal series was performed before discharge. Median hospital stay was 39 hours (24 – 312). Median follow up was 157 months (6 – 240), and dysphagia was resolved in 94% of patients. Seven patients required postoperative esophageal dilation.

Conclusions:

Minimally invasive Heller myotomy and Dor fundoplication are feasible. The operation is challenging, but excellent results hinge on the operative techniques and experience. The high dexterity, three-dimensional view, and the ergonomic movements of robotic surgery allow application of all the technical elements, achieving the best durable outcome for the patient. Robotic surgery is the natural evolution of minimally invasive treatment of esophageal achalasia.

Impact of Surgical Intervention on Nonobstructive Dysphagia: A Retrospective Study Based on High-Resolution Impedance Manometry in a Taiwanese Population at a Single Institution

Esophageal motility disorders account for a large proportion of nonobstructive dysphagia cases, which constitute a heterogeneous group of diagnoses that commonly result in peristaltic derangement and impaired relaxation of the lower esophageal sphincter. We performed a single-institution retrospective study enrolling consecutive patients with chief complaints of dysphagia who underwent HRIM from December 2014 to December 2019, and analyzed demographic, clinical, and manometric data using descriptive statistics. In total, 277 identified patients were included in the final analysis. Ineffective esophageal motility (n = 152, 24.5%) was the most common diagnosis by HRIM, followed by absent contractility, EGJ outflow obstruction, type II achalasia, and type I achalasia. Furthermore, surgery including exploratory, laparoscopic, and robotic myotomy, as well as POEM, is considered the most effective treatment for patients with non-spastic achalasia and EGJOO, due to its effective symptom palliation and prevention of disease progression; surgery also contributes to an obvious improvement of dysphagia compared with slightly less efficacy for other related symptoms. Our study aimed to elaborate the clinical characteristics of patients with nonobstructive dysphagia based on HRIM in a Taiwanese population, and to analyze the therapeutic outcomes of such patients who ultimately underwent surgical interventions.

Miotomia endoscópica peroral para o tratamento de acalásia no Sistema Único de Saúde (SUS): resultados de seguimento no curto-prazo

RESUMO Introdução: a acalasia é uma doença crônica. Por não haver tratamento curativo, os pacientes diagnosticados dispõem de técnicas farmacológicas e/ou cirúrgicas, visando minimizar o quadro. A POEM surge como um novo tipo de tratamento paliativo promissor com boas taxas de melhora dos sintomas. Objetivo: avaliar o perfil das POEM realizadas no Hospital das Clínicas da Universidade Federal de Pernambuco (HC - UFPE) e correlacioná-lo com o cenário mundial. Métodos: a coleta de dados foi realizada retrospectivamente no período de setembro de 2017 a outubro de 2019 com todos os pacientes submetidos a POEM no HC - UFPE. Variáveis sociodemográficas, clínicas e hospitalares foram avaliadas antes e três meses após o procedimento. Resultados: total de 27 pacientes (52,41 ± 19,24 anos) que realizaram o procedimento, 66,7% com etiologia idiopática e 33,3% com etiologia secundária à doença de Chagas. 48% tinham sido submetidos a procedimentos prévios, dos quais sete usaram algum tipo de medicamento para controle dos sintomas, dois foram submetidos à dilatação endoscópica pneumática e quatro à cardiomiotomia a Heller com fundoplicatura parcial. 62,5% dos pacientes avaliados tinham acalasia tipo ii antes do procedimento. Sete (25,9%) apresentaram eventos adversos: quatro sangramentos, dois pneumoperitônio e um ambas as complicações, todos foram tratados de forma conservadora. O escore de Eckardt reduziu de 8,37 ± 1,45 para 0,85 ± 1,06 (valor de p<0,001). Conclusão: melhora clínica e o perfil dos pacientes acompanhou a tendência mundial, destaque para a etiologia secundária à doença de Chagas, endêmica no Brasil. O refluxo gastroesofágico continua sendo o principal sintoma pós-operatório.

Beyond the Eckardt Score: Patient-Reported Outcomes Measures in Esophageal Disorders

PURPOSE OF REVIEW

To provide an overview of patient reported outcome measures (PROMs) and summarize their role in assessing undifferentiated dysphagia and common esophageal disorders, including achalasia, eosinophilic esophagitis (EoE), and gastroesophageal reflux disease (GERD).

RECENT FINDINGS

Given the subjective nature of swallowing disorders, accurate diagnoses often rely on capturing the patient experience. As a result, the number of PROMs used to characterize esophageal symptoms is increasing with a recent particular emphasis on EoE. Overall, esophageal-focused PROMs are used to interpret patient symptoms and quality of life, diagnosis, and symptom changes over time. There are limitations with each instrument, including factors affecting validity, reliability, accessibility, patient participation, and logistical implementation. PROM instruments can be helpful tools in the diagnosis and treatment of esophageal disorders. Instruments should be chosen based on factors such as target population and setting, including research, clinical, and quality improvement efforts. Future research should address how best to implement PROMs and integrate the obtained data with patient care.

One year comprehensive prospective follow-up of achalasia patients after peroral endoscopic myotomy

BACKGROUND AND AIMS

Peroral endoscopic myotomy (POEM) is an established therapy for achalasia, but outcome evaluation has often been limited to Eckardt score (ES). The present study was aimed to improve knowledge about outcome evaluation and predictive outcome factors by performing a comprehensive objective evaluation of achalasia patients treated by POEM.

METHODS

This single centre prospective study reports outcome data 12 months after POEM in treatment-naive achalasia patients. A predefined follow-up protocol included ES, high resolution manometry, 24-h pH measurement, upper endoscopy and timed barium esophagogram (TBE). Univariate and multivariate regression analyses were performed to analyze association between post-POEM variables and identify predictive factors for objective outcome.

RESULTS

Fifty patients were included with a drop-out rate of <5%. ES, lower oesophageal sphincter pressures, TBE heights and maximal oesophageal diameter were all reduced after POEM (p < .001), and 28% (13/47) of the patients had a positive 24-h pH registration. An oesophageal diameter >3 cm after POEM was associated with treatment failure assessed by ES (p = .04) and TBE (p = .03). Advanced achalasia stage (p = .02) and long symptom duration (p = .04) were identified as independent predictive factors for poor outcome assessed by TBE.

CONCLUSIONS

The present study confirms that POEM is an efficient therapy for achalasia. The comprehensive objective evaluation after POEM demonstrates that long symptom duration and major changes in oesophageal anatomy at diagnosis imply poor treatment outcome, and a post-POEM dilated oesophagus is associated with treatment failure.Key messagesPeroral endoscopic myotomy (POEM) is established as a safe and effective therapy for achalasia.Timed barium esophagogram offers objective variables that are valuable in treatment response evaluation. Advanced achalasia stage and long symptom duration are predictive factors for poor objective treatment response after POEM.

Implementation of a Timed Barium Esophagram Protocol for Assessment of Esophageal Function in Children

OBJECTIVES

Timed barium esophagram (TBE) is a fluoroscopic study that is widely employed as an adjunctive tool for diagnosing esophageal emptying disorders in adults (eg, achalasia, esophagogastric junction outflow obstruction [EGJOO]) and for following response to treatment. We aimed to describe the characteristics and feasibility of a pediatric TBE protocol and provide a first report of the potential value of TBE for assessment of esophageal emptying in the pediatric population.

METHODS

Retrospective chart review of pediatric patients at a tertiary pediatric hospital who underwent TBE from October 2017 to October 2019. Patient and test characteristics were summarized using descriptive statistics. Results from patients who had both TBE and high-resolution esophageal manometry (HRM) were used to generate ROC curves for TBE to identify esophageal emptying disorders.

RESULTS

Twenty-two patients underwent 25 TBE. Fourteen of 23 (61%) received 150 mL barium volume per protocol. Nearly half (42%) of subjects could tolerate ingesting barium within 20 seconds. Nine individuals underwent HRM. The sensitivity of standard adult TBE criteria (1 cm barium column height at 5 minutes) to detect emptying disorder was 100%, specificity 40%. A modified diagnostic cutoff (1.6 cm height at 5 minutes) offered 100% sensitivity, 80% specificity.

CONCLUSIONS

TBE is feasible and should be considered an adjunctive noninvasive screen for impaired esophageal emptying in children. There was heterogeneous adherence to protocol for timing and volume of barium; however, studies remained interpretable. This population may benefit from different diagnostic cutoffs than adults, and clinical judgment should be used until specific diagnostic cutoffs are determined in children.

Ineffective esophageal motility is not a contraindication to total fundoplication

INTRODUCTION

Ineffective esophageal motility (IEM) is a physiologic diagnosis and is a component of the Chicago Classification. It has a strong association with gastroesophageal reflux and may be found during work-up for anti-reflux surgery. IEM implies a higher risk of post-op dysphagia if a total fundoplication is done. We hypothesized that IEM is not predictive of dysphagia following fundoplication and that it is safe to perform total fundoplication in appropriately selected patients.

METHODS

Retrospective chart review of patients who underwent total fundoplication between September 2012 and December 2018 in a single foregut surgery center and who had IEM on preoperative manometry. We excluded patients who had partial fundoplication, previous foregut surgery, other causes of dysphagia or an esophageal lengthening procedure. Dysphagia was assessed using standardized Dakkak score ≤ 40 and GERD-HRQL question 7 ≥ 3.

RESULTS

Two hundred patients were diagnosed with IEM and 31 met the inclusion criteria. Median follow-up: 706 days (IQR 278-1348 days). No preoperative factors, including subjective dysphagia, transit on barium swallow, or individual components of manometry showed statistical correlation with postoperative dysphagia. Of 9 patients with preoperative dysphagia, 2 (22%) had persistent postoperative dysphagia and 7 had resolution. Of 22 patients without preoperative dysphagia, 3 (14%) developed postoperative dysphagia; for a combined rate of 16%. No patient needed re-intervention beyond early recovery or required reoperation for dysphagia during the follow-up period.

CONCLUSION

In appropriately selected patients, when total fundoplication is performed in the presence of preoperative IEM, the rate of long-term postoperative dysphagia is similar to the reported rate of dysphagia without IEM. With appropriate patient selection, total fundoplication may be performed in patients with IEM without a disproportionate increase in postoperative dysphagia. The presence of preoperative IEM should not be rigidly applied as a contraindication to a total fundoplication.
