Persisting symptoms and decreased health-related quality-of-life in a cross-sectional study of treated achalasia patients

Landscape of Psychological Profiles in Patients With Esophageal Achalasia

INTRODUCTION

Esophageal achalasia (EA) is a chronic esophageal dysmotility disease, of which psychological distress was poorly understood. This study aims to assess the status of psychosocial characteristics in EA and to determine the relationship between psychological distress and EA.

METHODS

Seventy pairs of age and gender-matched patients with EA and healthy control individuals were prospectively enrolled from December 2019 to April 2020 at our hospital. Demographic, psychosocial, and clinical data were obtained. Psychosocial assessments contained psychological distress (Symptom Checklist-90 Revised), perceived stress (Perceived Stress Scale-14), and stressful life events (Life Events Scale). Comparison for psychological parameters was made between patients with EA and controls as well as for EA before/after per oral endoscopic myotomy (POEM). Spearman rank correlation coefficients were used to testify the association between psychological distress and achalasia symptoms.

RESULTS

The mean course and Eckardt score of patients with EA were 4.26 ± 5.11 years and 6.63 ± 2.21, respectively. There was a significant difference between patients with EA and healthy individuals in Global Severity Index ( P = 0.039) and Positive Symptoms Total ( P = 0.041) for Symptom Checklist-90 Revised as well as positive intensity ( P = 0.011) for the Life Events Scale. Somatization ( P < 0.001), anxiety ( P = 0.021), anger-hostility ( P = 0.009), and others (appetite and sleep, P = 0.010) accounted for the most difference. Somatization was positively associated with chest pain ( P = 0.045). Two patients with EA developed recurrence and showed no relationship with psychological status. Psychological status was significantly improved after POEM.

DISCUSSION

Psychological distress, especially somatization, was more prevalent in patients with EA than healthy controls. POEM seemed able to improve psychological distress.

Per-oral endoscopic myotomy is safe and effective for pediatric patients with achalasia: A long-term follow-up study

BACKGROUND

Per-oral endoscopic myotomy (POEM) is emerging as a prefer treatment option for pediatric achalasia. However, data are limited on the long-term efficacy of POEM in children and adolescents with achalasia.

AIM

To evaluate the safety and long-term efficacy of POEM for pediatric patients with achalasia and compare those outcomes with adult patients.

METHODS

This retrospective cohort study was conducted in patients with achalasia who underwent POEM. Patients aged under 18 years were included in the pediatric group; patients aged between 18 to 65 years who underwent POEM in the same period were assigned to the control group. For investigation of long-term follow-up, the pediatric group were matched with patients from the control group in a 1:1 ratio. The procedure-related parameters, adverse events, clinical success, gastroesophageal reflux disease (GERD) after POEM, and quality of life (QoL) were evaluated.

RESULTS

From January 2012 to March 2020, POEM was performed in 1025 patients aged under 65 years old (48 in the pediatric group, 1025 in the control group). No significant differences were observed in the occurrence of POEM complications between the two groups (14.6% vs 14.6%; P = 0.99). Among the 34 pediatric patients (70.8%) who underwent follow-up for 5.7 years (range 2.6-10.6 years), clinical success was achieved in 35 patients (35/36; 97.2%). No differences were observed in post-POEM GERD occurrence (17.6% vs 35.3%; P = 0.10). QoL was significantly improved in both groups after POEM.

CONCLUSION

POEM is safe and effective for pediatric patients with achalasia. It can achieve significant symptoms relief and improve QoL.

Psychological burden of achalasia: Patients' screening rates of depression and anxiety and sex differences

OBJECTIVE

Achalasia is associated with reduced quality of life in affected patients but research regarding the psychological burden of achalasia in terms of depression and anxiety is scarce. The current study therefore aims to investigate rates of depression and anxiety in patients with achalasia in relation to prevalence rates in the general population and to examine the extent to which achalasia-related characteristics (time since diagnosis, symptom load, achalasia-related quality of life, treatment history) predict symptoms of depression and anxiety.

METHODS

Using validated screening instruments, rates of depression and anxiety were assessed in a cross-sectional survey of a sample of 993 patients with achalasia and compared to population controls stratified by age and sex. Associations between depression and anxiety and achalasia-related factors were explored using linear regression.

RESULTS

Compared to population controls, screening rates of female patients with achalasia were between 3.04 (p = .004) and 7.87 (p < .001) times higher for depression and 3.10 (p < .001) times higher for anxiety, respectively. No significant differences were found for male patients with achalasia. Both achalasia-related quality of life and symptom load were independently related to impaired mental health.

CONCLUSION

Women appear to be specifically affected by the psychological burden of achalasia, pointing to sex-specific or gendered experiences of the disease. In addition to symptom reduction, psychological support may prove beneficial for improving the well-being of patients with achalasia.

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.

European guidelines on achalasia: United European Gastroenterology and European Society of Neurogastroenterology and Motility recommendations

INTRODUCTION

Achalasia is a primary motor disorder of the oesophagus characterised by absence of peristalsis and insufficient lower oesophageal sphincter relaxation. With new advances and developments in achalasia management, there is an increasing demand for comprehensive evidence-based guidelines to assist clinicians in achalasia patient care.

METHODS

Guidelines were established by a working group of representatives from United European Gastroenterology, European Society of Neurogastroenterology and Motility, European Society of Gastrointestinal and Abdominal Radiology and the European Association of Endoscopic Surgery in accordance with the Appraisal of Guidelines for Research and Evaluation II instrument. A systematic review of the literature was performed, and the certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Recommendations were voted upon using a nominal group technique.

RESULTS

These guidelines focus on the definition of achalasia, treatment aims, diagnostic tests, medical, endoscopic and surgical therapy, management of treatment failure, follow-up and oesophageal cancer risk.

CONCLUSION

These multidisciplinary guidelines provide a comprehensive evidence-based framework with recommendations on the diagnosis, treatment and follow-up of adult achalasia patients.

High-resolution manometric guidance during laparoscopic Heller myotomy: Impact on quality of life and symptom severity for children with achalasia

BACKGROUND

High-resolution esophageal manometry (HREM) during laparoscopic Heller myotomy (LHM) with fundoplication for achalasia allows tailoring of myotomy length and wrap tightness. The purpose of this study is to quantify long-term postoperative symptom severity and quality of life using validated questionnaires.

METHODS

Children ≤18 years with achalasia who previously underwent LHM with intraoperative HREM from 2010 to 2017 were prospectively surveyed. Eckardt Symptom Score (ESS), Achalasia Severity Questionnaire (ASQ), Pediatric Quality of Life Inventory (PedsQL), and Pediatric GERD Symptom and Quality of Life (PGSQ) questionnaires were administered. Scores for historical controls were obtained from prior survey instrument validation studies as comparison.

RESULTS

Of 30 eligible patients, 12 (40%) completed the surveys. Mean age at time of surgery was 13 ± 3 years. Assessment was performed at least 10 months after surgery with mean time elapsed of 3.6 ± 2 years. Average premyotomy lower esophageal sphincter (LES) pressure, postmyotomy LES pressure, and postfundoplication LES pressure were 30 ± 10 mmHg, 14 ± 6 mmHg, and 18 ± 9, respectively. ESS (2.3/12), ASQ (39/100 ± 16), PGSQ (symptom: 0.6/4 ± 0.4, school: 0.4/4 ± 0.4), and overall PedsQL (82/100 ± 15) were similar to those of healthy historical controls.

CONCLUSION

Children with achalasia undergoing LHM with intraoperative HREM had sustained long-term symptom improvement and quality of life scores comparable to healthy patients.

Heller's myotomy and pneumatic dilatation in the treatment of achalasia: a population-based case-control study assessing long-term quality of life

Long-term health-related quality-of-life (HRQL) outcomes have not been widely reported in the treatment of achalasia. The aims of this study were to examine long-term disease-specific and general HRQL in achalasia patients using a population-based case-control method, and to assess HRQL between treatment interventions. Manometrically diagnosed achalasia cases (n = 120) were identified and matched with controls (n = 115) using a population-based approach. Participants completed general (SF-12) and disease-specific (Achalasia Severity Questionnaire [ASQ]) HRQL questionnaires, as appropriate, in a structured interview. Mean composite scores for SF-12 (Mental Component Summary score [MCS-12] and Physical Component Summary score [PCS-12]) and ASQ were compared between cases and controls, or between intervention groups, using an independent t-test. Adjusted mean differences in HRQL scores were evaluated using a linear regression model. Achalasia cases were treated with a Heller's myotomy (n = 43), pneumatic dilatation (n = 44), or both modalities (n = 33). The median time from last treatment to HRQL assessment was 5.7 years (interquartile range 2.4-11.5). Comparing achalasia patients with controls, PCS-12 was significantly worse (40.9 vs. 44.2, P = 0.01), but MCS-12 was similar. However, both PCS-12 (39.9 vs. 44.2, P = 0.03) and MCS-12 (46.7 vs. 53.5, P = 0.004) were significantly impaired in those requiring dual treatment compared with controls. Overall however, there was no difference in adjusted HRQL between patients treated with Heller's myotomy, pneumatic dilatation or both treatment modalities. In summary, despite treatment achalasia patients have significantly worse long-term physical HRQL compared with population controls. No HRQL differences were observed between the treatment modalities to suggest a benefit of one treatment over another.

Achalasia-Specific Quality of Life After Pneumatic Dilation or Laparoscopic Heller Myotomy With Partial Fundoplication: A Multicenter, Randomized Clinical Trial

OBJECTIVES

Achalasia is a chronic, progressive, and incurable esophageal motility disease. There is clinical uncertainty about which treatment should be recommended as first-line therapy. Our objective was to evaluate the effectiveness of pneumatic dilation compared with laparoscopic Heller myotomy with partial fundoplication in improving achalasia-specific quality of life.

METHODS

This was a prospective, multicenter, randomized trial at five academic hospitals in Canada. Fifty previously untreated adults with a clinical diagnosis of primary achalasia, confirmed by manometric testing, were enrolled between November 2005 and March 2010, and followed for 5 years after treatment. Randomization was stratified by site, in random blocks of size four and with balanced allocation. Patients were treated with pneumatic dilation or laparoscopic Heller myotomy with partial fundoplication. The primary outcome was the difference between the treatments in the mean improvement of the achalasia severity questionnaire (ASQ) score at 1 year from baseline. Prespecified secondary outcomes included general and gastrointestinal quality of life, symptoms, esophageal physiology measures (lower esophageal sphincter relaxation and pressure, esophageal emptying, abnormal esophageal acid exposure), complications, and incidence of retreatment. Functional and imaging studies were performed blinded and all outcome assessors were blinded.

RESULTS

There were no significant differences between treatments in the improvement of ASQ score at 1 year from baseline (27.5 points in the Heller myotomy arm vs. 20.2 points in the pneumatic dilation arm; difference 7.3 points, 95% confidence interval -4.7 to 19.3; P=0.23). There were no differences between treatments in improvement of symptoms, general and gastrointestinal quality of life, or measures of esophageal physiology. Improvements in ASQ score diminished over time for both interventions. At 5 years, there were no differences between treatments in improvement of ASQ score, symptoms, and general or gastrointestinal quality of life. There were no serious adverse events. No patient who received Heller myotomy required retreatment, whereas five patients treated initially with pneumatic dilation required retreatment.

CONCLUSIONS

Treatment with pneumatic dilation or laparoscopic Heller myotomy similarly improves achalasia-specific disease severity at 1 year. Either of the therapeutic approaches can be used as first-line therapy for previously untreated adults with achalasia.

Patient-Reported Outcomes in Eosinophilic Esophagitis and Achalasia

OPINION STATEMENT

The activity of a particular esophageal disease, such as eosinophilic esophagitis (EoE) or achalasia, can be evaluated using clinician-reported outcome (ClinRO) measures assessing various endoscopic, histologic, functional, and laboratory findings, and patient-reported outcome (PRO) measures. The patient-reported outcome (PRO) measures are those that are designed to be self-reported by patients. Commonly used PRO instruments include those that assess symptom severity, health-related quality of life, "general" quality of life, or health status. Regulatory authorities increasingly rely on PRO measures to support labeling claims for drug development. Validated PRO measures for various esophageal diseases are needed in order to unify and standardize the way disease activity is assessed, define clinically meaningful endpoints for use in interventional and observational studies, compare the efficacy/effectiveness of various therapies, and optimize therapeutic algorithms for management of these diseases. This article reviews commonly used PRO instruments designed to assess symptom severity and quality of life in adult patients with EoE and achalasia.

Pediatric Achalasia in the Netherlands: Incidence, Clinical Course, and Quality of Life

OBJECTIVE

To assess incidence and clinical course of Dutch patients with achalasia diagnosed before 18 years of age as well as their current symptoms and quality of life (QoL).

STUDY DESIGN

Retrospective medical chart review and a cross-sectional study assessing current clinical status using the Eckardt score and reflux disease questionnaire. General QoL was measured using Kidscreen-52 for patients <18 years of age or to 36-Item Short Form Health Survey for patients ≥18 years of age.

RESULTS

Between 1990 and 2013, 87 children (mean age 11.4 ± 3.4 years, 60% male) diagnosed with achalasia in the Netherlands were included. Mean incidence was 0.1/100,000/y (range 0.03-0.21). Initial treatment was pneumodilation (PD) in 68 (79%) patients and Heller myotomy (HM) in 18 (21%) patients. Retreatment was required more often after initial PD compared with initial HM (88% vs 22%; P < .0001). More complications of initial treatment occurred after HM compared with PD (55.6% vs 1.5%; P < .0001). Three esophageal perforations were seen after HM (16.7%), 1 after PD (1.5%). Sixty-three of 87 (72%) patients were prospectively contacted. Median Eckardt score was 3 (IQR 2-5), with 32 patients (44.5%) having positive scores suggesting active disease. Reflux disease questionnaire scores were higher after initial HM vs PD (1.71 [0.96-2.90] vs 0.58 [0-1.56]; P = .005). The 36-Item Short Form Health Survey (n = 52) was lower compared with healthy population norms for 7/8 domains. Kidscreen-52 (n = 20) was similar to population norms.

CONCLUSIONS

Pediatric achalasia is rare and relapse rates are high after initial treatment, especially after pneumodilation, but with more complications after HM. Symptoms often persist into adulthood, without any clinical follow-up. QoL in adulthood was decreased.

Diagnostic yield of 96-h wireless pH monitoring and usefulness in patients' management

OBJECTIVE

To get insight into usefulness of 96-h wireless monitoring in diagnosis of gastro-esophageal reflux disease (GERD) and in patients' management.

MATERIAL AND METHODS

51 patients who underwent 96-h wireless and 51 matched patients who underwent 24-h traditional pH monitoring were enrolled and retrospectively contacted with a structured telephone interview.

RESULTS

In the wireless group, the 96-h recording improved (p < 0.05) the diagnostic yield compared with the first 48-h recording by allowing Symptom Association Probability to be measured in eight more patients and by decreasing indeterminate tests from 11 to 5. After pH monitoring, concordance between results of the test and treatment for GERD was higher in the wireless compared with the traditional group, 78% versus 58% of the patients (p < 0.05). Both improvement/disappearance of the clinically relevant symptom and satisfaction (score of 1-10) at time of the telephone interview were however similar in the two groups, 73% versus 65% and 7.0 versus 6.5.

CONCLUSIONS

Wireless pH monitoring prolonged to 96 h increased the likelihood to exclude/confirm GERD as the cause of the clinically relevant symptoms in those patients with an indeterminate result for GERD after the first 48 h. Outcome was however similar to the one of traditional pH monitoring.

Health-related quality of life in children with achalasia

AIMS

To assess self-reported QoL in children with achalasia aged 5-18 and compare this with both disease and healthy control children in a prospective study.

METHODS

All children diagnosed with achalasia at one hospital were asked to participate in this study by completing the self-report module of the validated PedsQL™ generic QoL assessment. All children attending a tertiary paediatric gastroenterology clinic from February 2009 to May 2009 with chronic constipation or inflammatory bowel disease were asked to participate in this study as disease controls. The PedsQL™ considers physical, emotional, social and school domains and is scored from 0-100. Healthy children were also recruited from the same site. Groups were compared using Analysis of Variance with Tukey's post-hoc test.

RESULTS

One hundred and sixty one children completed the assessment (90 (56%) male, mean age 11.3 yrs ± 3.4 years) including 17 children with achalasia, 44 with chronic constipation, 59 with inflammatory bowel disease and 41 healthy children. QoL was significantly lower in the achalasia group compared to both children with IBD (73 vs. 82, p = 0.035) and healthy children (73 vs. 84, p = 0.005), and was comparable to that of children with chronic constipation (73 vs. 74, p = 0.99).

CONCLUSION

Children with achalasia report a significantly lower QoL compared to children with inflammatory bowel disease and healthy children.

Effect of laparoscopic esophagomyotomy on chest pain associated with achalasia and prediction of therapeutic outcomes

BACKGROUND

The effect of myotomy for achalasia on chest pain has not been clarified. The current study aimed to investigate the therapeutic effect of laparoscopic myotomy on chest pain associated with achalasia and to identify prognostic factors for outcomes.

METHOD

Between March 2005 and September 2008, 95 patients were available for detailed interviews and for assessment of clearance by timed barium esophagogram (TBE) before and after surgery. Of the 95 patients, 47 (24 men; mean age, 42.9 ± 13.5 years) who experienced chest pain before surgery were studied. The subjects were asked in detail about dysphagia and chest pain before surgery and 6 months after surgery. The frequency and severity of the symptoms were graded on a scale of 0 to 4. In addition, the values obtained by multiplying the grade for frequency by the grades for severity of the two symptoms were defined as the dysphagia score and the chest pain score, respectively. The patients with chest pain scores of 0 after surgery were defined as group A and those with scores smaller than their preoperative scores as group B. The remaining patients with other scores were defined as group C. The background factors and clinical conditions of the three groups were compared.

RESULTS

The mean chest pain score decreased from 5.0 ± 3.2 to 1.0 ± 1.6 (p < 0.001). The score after surgery was 0 for 27 patients and showed a decrease for 15 patients. Although the three groups did not differ in their characteristics, differences were noted in postoperative TBE factors (i.e., groups A and B had significantly shorter barium columns than group C at 1 and 5 min after surgery (p = 0.001).

CONCLUSION

Laparoscopic myotomy had a therapeutic effect on chest pain associated with achalasia, and improvement in postoperative esophageal clearance may influence the therapeutic effect.

Disease-specific health-related quality of life in patients with esophageal achalasia before and after therapy

BACKGROUND

To evaluate disease-specific health-related quality of life (HRQoL) in patients with symptomatic esophageal achalasia before and after therapy.

METHODS

Symptoms and disease-specific HRQoL were evaluated before and 3 months after therapy. Therapy selection, either dilatation or myotomy, depended exclusively on the opinion of the physician on charge of the patient. Symptom severity was graded from 0 to 3, using a scoring system. A disease-specific questionnaire for achalasia developed and validated in Spanish language with 18 items and four subscales (AE-18) was used to evaluate HRQoL. Changes after therapy in HRQoL and its association with clinical improvement were analyzed.

KEY RESULTS

Sixty-five patients were prospectively included in eight hospitals in Spain. Of them, 47 were treated with dilatation, and 18 with laparoscopic Heller myotomy. After therapy, AE-18 global and subscales scores improved significantly. Changes in HRQoL were associated with improvement in symptoms. An important improvement in symptoms (>or=50%) was needed to obtain a minimal clinically important improvement (>or=20%) in HRQoL.

CONCLUSIONS & INFERENCES

Disease-specific HRQoL improves in patients with symptomatic achalasia after therapy with dilatation or myotomy. The degree of improvement of HRQoL depends on the degree of improvement of esophageal symptoms.

A pneumatic dilation strategy in achalasia: prospective outcome and effects on oesophageal motor function in the long term

BACKGROUND

Long-term follow-up studies of achalasia after pneumatic dilation, mostly retrospective, have shown variable results.

AIM

To examine the outcome of achalasia after pneumatic dilation using a prospective follow-up programme.

METHODS

One or two dilations (first dilation treatment) in 77 patients to achieve stable (>1 year) remission and patients followed up with yearly clinical and manometric assessments. Endoscopy, pH monitoring and barium swallow were also performed.

RESULTS

A total of 69 patients achieved stable remission and were followed up for 5.6 years (3-10.7) [median (IQ range)], whereas six patients underwent cardiomyotomy and two experienced a perforation. Twelve of the 69 patients relapsed after 2.6 years (1.7-5.1): nine of 12 underwent one to two further dilations. Six-year remission rate (by Kaplan-Meyer estimates) was 82% after first dilation treatment and 96% after all dilations. Continuous antisecretory treatment was clinically needed in 16%, oesophagitis present in 7% and reflux pathological in 28% of the patients. Beneficial effects of dilation on oesophageal motility and on diameter of the oesophageal body at barium swallow were maintained during follow-up.

CONCLUSIONS

A management strategy including sessions of pneumatic dilation until stable remission and a standardized follow-up is highly successful in the long term. Gastro-oesophageal reflux is clinically relevant in a minority of patients.

Clinical predictors of achalasia

Limited access to esophageal manometry (EM) may delay identification and treatment of patients with achalasia. In order to assess predictors to fast-track patients for manometric confirmation of achalasia, we compared the clinical, radiographic, and endoscopic characteristics of achalasia patients to patients with functional dysphagia without manometric features of achalasia (controls). Patients referred for esophageal manometry to assess functional dysphagia prospectively identified over a 12-month period were asked to participate in this study. The Achalasia Symptom Questionnaire (ASQ), a structured 11-question survey (score: 0-best, 67-worst), was completed by all consenting patients. ASQ scores, esophago-gastro-duodenoscopy and upper gastro-intestinal (UGI) contrast study findings were compared between patents with subsequently confirmed achalasia and those in whom achalasia was excluded by EM. Univariate logistic regression identified predictors that were tested by multivariate logistic regression to generate the model. Of the 803 EM performed over this 12-month period, 95 patients were referred specifically to assess functional dysphagia. Of these, 50 were confirmed to have achalasia, and 45 had dysphagia without manometric evidence for achalasia and hence comprised the control group. ASQ scores were higher in achalasia patients (37+/-13 versus 23+/-10). Endoscopy and/or contrast esophagogram reports were available in 92% achalasia patients and 80% controls. Significant predictors for achalasia identified on univariate logistic regression included ASQ score, abnormal findings on endoscopy, and contrast UGI study. Using multivariate logistic regression, we were able to accurately predict the probability of achalasia to be P where P=ey/(1+ey) and y=5.6+(0.089xASQ)+(2.088xEGD)+(3.083xUGI), e=exponential constant 2.7182, esophagogastroduodenoscopy (EGD) and UGI=0 if normal and 1 if abnormal. Dropping the predictor ASQ, the formula changes to y=-2.7+(1.987xEGD)+(2.861xUGI). Using only noninvasive investigations (i.e. eliminating EGD), the formula changes to y=-4.9653+(0.0951xASQ)+(3.4312xUGI). The probability of achalasia can be calculated in patients with functional dysphagia based on clinical, endoscopic, and radiographic findings allowing for a prioritization of EM studies.

Functional dyspepsia and irritable bowel syndrome in patients with achalasia and its association with non-cardiac chest pain and a decreased health-related quality of life

OBJECTIVE

In patients with achalasia, little is known about symptoms of the gastrointestinal tract other than the esophagus. The purpose of this study was to determine the prevalence of two functional disorders, functional dyspepsia (FD) and irritable bowel syndrome (IBS), in a group of treated achalasia patients and to assess the additional impact of these disorders on health-related quality of life (HRQoL).

MATERIAL AND METHODS

Questionnaires assessing the Rome II criteria for FD and IBS together with the Eckardt clinical symptom score and RAND-36 were sent to 171 treated achalasia patients.

RESULTS

Of these patients, 76.6% returned their questionnaires. In the group of achalasia patients, 23% fulfilled the criteria for FD (Dutch general population 13-14%), and 21% fulfilled the criteria for IBS (Dutch general population 1-6%). The prevalence of frequent chest pain (at least weekly) was higher in patients with FD and/or IBS than in those without these symptoms (54.2% versus 28.2%; p=0.004). Female patients with achalasia and with frequent chest pain showed a higher probability of fulfilling the FD and/or IBS criteria (adjusted OR 2.90 (1.18-7.14) and 3.35 (1.4-8.1), respectively; both with p <0.05). Patients fulfilling the FD and/or IBS criteria scored a lower HRQoL on the RAND-36 subscales--pain, social functioning, and vitality--as compared with patients not fulfilling these criteria (p <0.006). CONCLUSIONS; Symptoms of FD and IBS in patients with treated achalasia are common and have a negative impact on HRQoL. Therefore, this has to be included in the standard evaluation of achalasia patients. The association with chest pain suggests a mutual underlying mechanism.

Evaluation of the response to treatment in patients with idiopathic achalasia by the timed barium esophagogram: results from a randomized clinical trial

To choose which treatment would be most effective for the individual patient with newly diagnosed achalasia is difficult for the tending physician. A diagnostic tool that would allow prediction of the symptomatic and functional response after treatment for achalasia is therefore needed. The timed barium esophagogram (TBE) is a method that allows objective assessment of esophageal emptying, but the value of TBE in the clinical management of achalasia remains to be clarified. The aim of this study was first, to assess the ability of TBE to predict symptoms and treatment failure during post-treatment follow-up. Second, to determine whether esophageal emptying as assessed by TBE differs after treatment with pneumatic dilatation or laparoscopic myotomy. Fifty-one patients with newly diagnosed achalasia were prospectively randomized to pneumatic dilatation (n = 26) or laparoscopic myotomy (n = 25). Evaluation with TBE was performed before (n = 46) and after treatment (n = 43). The median interval between treatment and post-treatment TBE was 6 months, and the median follow-up time after the post-treatment TBE was 18 months. Following therapeutic intervention, TBE parameters did not differ significantly between treatment groups. However, significant correlations were found between the height of the barium column at 1 min and the symptom scores at the end of follow up for 'dysphagia for liquids' (P < 0.05, rho = 0.47), 'chest pain' (P < 0.05, rho = 0.42), and the 'Watson dysphagia score' (P < 0.05, rho = 0.46). Patients with less than 50% improvement in this TBE-parameter (height at 1 min) post-treatment had a 40% risk of treatment failure during follow-up. In summary, pneumatic balloon dilatation and laparoscopic myotomy similarly affected esophageal function as assessed by TBE-emptying. Lack of improvement in barium-column height post-treatment was associated with an increased risk of treatment failure which should motivate close surveillance in order to detect symptomatic recurrence at an early stage.
