COVID-19 pandemic and lockdown stress consequences in people with and without Irritable Bowel Syndrome.

BACKGROUND: While all resources have been mobilized to fight COVID-19, this study aimed to analyze the consequences of lockdown and pandemic stress in participants with and without Irritable Bowel Syndrome (IBS). METHODOLOGY: An online survey was proposed to people with or without IBS during the exponential phase of the pandemic in France. The questionnaire included questions about socio-demographic data, conditions of confinement, activities carried out, IBS characteristics, measurement of stress level, consequences on sleep, fatigue, anxiety and depression, and quality of life (both perceived non-specific and specific for IBS). RESULTS/DISCUSSION: From March 31 to April 15, 2020, 304 participants, 232 with IBS and 72 without were included in the survey (mean age: 46.8 ± 16.8 years, female gender: 75.3%). Age, level of education, financial resources, living space per person and activities performed during confinement were identical in both groups. Stress linked to fear of COVID-19, lockdown and financial worries was at the same level in both groups, but the psychological consequences and deterioration of quality of life (QOL) were both higher in IBS participants. In a univariate analysis, teleworking, solitary confinement, and low household resources had a variable impact on the scores of depression, anxiety, fatigue and non-specific perceived QOL, but in a multivariate analysis, the only factor explaining a deterioration of non-specific QOL was the fact of suffering from IBS. CONCLUSION/PERSPECTIVES: Stress linked to the COVID-19 pandemic and confinement is high and equivalent in both IBS and non-IBS participants, with higher psychological and QOL consequences in IBS patients who have altered coping capacities.

Expectations of IBS patients concerning disease and healthcare providers: Results of a prospective survey among members of a French patients' association.

BACKGROUND AND AIMS: IBS patients have an impaired quality of life (QoL) and feel dissatisfaction with medical care. We aim to describe the expectations of members of the French Association of IBS patients (APSSII) concerning health care providers (HCPs) and a patients' organization. PATIENTS AND METHODS: From January to June 2013, APSSII members were asked to answer questionnaires on their expectations and experiences concerning IBS and HCP. RESULTS: 222/330 (67%) responded (women: 68.5%, 46.5±17.7 years, disease duration: 8.8±0.7 years, IBS-D 33.6%, IBS-C 26.7%, IBS-M 38.2%. IBS-SSS>300 in 53% and HAD score>19 in 45%). QoL impairment was correlated with disease severity and HAD score (r=-0.707 and r=-0.484, P<0.001 respectively), but not with IBS subtype. Expectations for IBS were "improved health", "better information on causes and treatments" (94%) and "better disease recognition" (86%). A significant gap was observed between expectations and experiences with HCPs. Better information, less isolation, recognition of the disease and a decrease in medical expenses were the main expectations for joining a patients' organization. CONCLUSIONS: French IBS patients have a severe disease with a significant psychological impact and impaired QoL in half of the patients, certain unsatisfied expectations concerning HCP and high expectations in joining a patients' organization.

Sacral nerve modulation for faecal incontinence: influence of age on outcomes and complications. A multicentre study.

AIM: Faecal incontinence is frequent in the elderly. Little is currently known about the efficacy of sacral nerve modulation (SNM) in the elderly. The present study aimed to assess the impact of age on the outcome of SNM and on the surgical revision and explantation rates by comparing the results of a large data set of patients. METHOD: Prospectively collected data from patients who underwent an implant procedure between January 2010 and December 2015 in seven French centres were retrospectively evaluated. In total, 352 patients [321 women; median age (range): 63 (24-86) years] were included. Clinically favourable and unfavourable outcomes, and surgical revision and explantation rates, were compared according to the age of the patients. RESULTS: A similar outcome was observed when comparing patients < 70 years and ≥ 70 years (a favourable outcome in 79.2% and 76.2%, respectively, P = 0.89). The probability of a successful treatment as a function of time was similar for the two age groups (< 70 years and ≥ 70 years, P = 0.54). The explantation and revision rates were not influenced by age (explantation rate: 17% in patients < 70 years vs 14% in patients ≥ 70 years, P = 0.89; and revision rate: 42% in patients < 70 years vs 40% in patients ≥ 70 years, P = 0.89). The probability of explantation as a function of time was similar for the two age groups (P = 0.82). The limitations of this study were its retrospective status, the rate of loss at follow-up and different durations of patient follow-up. CONCLUSIONS: Our results suggest that patients ≥ 70 years suffering from faecal incontinence benefit from SNM with a similar risk as a younger population.

Rapid drink challenge test during esophageal high resolution manometry in patients with esophago-gastric junction outflow obstruction.

BACKGROUND: Esophago-gastric junction (EGJ) outflow obstruction is of unclear significance. Rapid drink challenge (RDC) test is easy to perform during esophageal high resolution manometry. We aimed to assess the yield of RDC test in patients with EGJ outflow obstruction. METHODS: Manometry studies of patients with EGJ outflow obstruction according to the Chicago Classification v3.0 were retrospectively reviewed. Pan-esophageal pressurization (PEP), esophageal shortening, and pressure gradient across the EGJ were analyzed during RDC test (200-mL free drinking in sitting position) and compared according to the causes of EGJ outflow obstruction determined by charts review. KEY RESULTS: Seventy-five patients (29 males, mean age 62 years) were included. Causes of EGJ outflow obstruction were previous esophago-gastric surgery (40%), incomplete form of achalasia (7%), mediastinal neoplasia (7%), other associated conditions (21%), and undetermined (25%). Rapid drink challenge test was successfully performed in 70 patients and associated with PEP and shortening in 41% and 13%, respectively. The causes of EGJ outflow obstruction were similarly distributed in patients with and without PEP during RDC test. Esophageal shortening tended to be more likely in patients with definitive findings of obstruction (achalasia, previous surgery, neoplasia) than in the others. Dysphagia was more severe in patients with PEP and/or shortening during RDC test compared to those without. CONCLUSIONS & INFERENCES: Pan-esophageal pressurization and esophageal shortening were associated with symptoms severity but did not predict the cause of this disorder. Further prospective studies are necessary to determine if RDC test could help to select patients who might benefit from treatment.

Prevalence of fecal incontinence in a cohort of systemic sclerosis patients within a regional referral network.

BACKGROUND: The prevalence of gastrointestinal involvement in systemic sclerosis is higher than 75%. The estimated prevalence of fecal incontinence varies from 22% to 77%, but suffers from recruitment bias and patient reluctance. Our goal was to evaluate the prevalence of fecal incontinence in systemic sclerosis, and to identify associated risk factors. METHODS: Patients were recruited in the referral systemic sclerosis network of the Lyon University Hospitals, using self-administered questionnaires including constipation, fecal incontinence and Bristol Stool scales, quality of life, anxiety and depression. The cohort was compared with the historical ORALIA cohort that established the prevalence of fecal incontinence in the general population of the Rhône-Alpes region (France). RESULTS: Seventy-seven patients were included (mean age: 60 years, range: 32-84), and 86% were female. These were compared to 153 ORALIA individuals matched for age and sex. Fecal incontinence was present in 38% of patients and 6% of the general population. A longer duration of systemic sclerosis was the only characteristic associated with fecal incontinence. Abnormal stool consistency was more frequent in patients with fecal incontinence. CONCLUSION: Fecal incontinence and abnormal stool consistency are common in systemic sclerosis and should be systematically addressed.

3D High-definition anorectal manometry: Values obtained in asymptomatic volunteers, fecal incontinence and chronic constipation. Results of a prospective multicenter study (NOMAD).

BACKGROUND: 3D-high definition anorectal manometry (3DARM) may aid the diagnosis of functional anorectal disorders, but data comparing asymptomatic and symptomatic subjects are scarce. We aimed to describe 3DARM values in asymptomatic volunteers and those with fecal incontinence (FI) or chronic constipation (CC), and identify which variables differentiate best these groups. METHODS: Asymptomatic subjects were stratified by sex, age, and parity. Those with FI or CC were included according to anorectal symptom questionnaires. Endoanal ultrasound examination and 3DARM were performed the same day. Anal pressures were analyzed at rest, during voluntary squeeze, and during push maneuver, and compared between the 3 groups. Anal pressure defects were defined and compared to ultrasound defects. KEY RESULTS: A total of 126 subjects (113 female, mean age 52 years, range 18-83) were included; 36 asymptomatic, 38 FI, 42 CC. Anal resting and squeeze pressures, and rectal sensitivity values were lower in FI women than in the other groups. Typical anal sphincter asymmetry during squeezing was less frequently observed in FI women. A dyssynergic pattern during push maneuver was found in 70% of asymptomatic subjects, and with a similar frequency in the 2 symptomatic groups. There was slight concordance between 3D-pressure defects and ultrasound defects. CONCLUSIONS & INFERENCES: 3D anal pressures in asymptomatic women were significantly lower than in men, and in FI compared to asymptomatic women. The classical dyssynergic pattern during push maneuver was found as frequently in asymptomatic and symptomatic patients. Further studies should try to identify 3DARM variables that could reliably identify dyssynergic defecation.

Validation of criteria for the definition of transient lower esophageal sphincter relaxations using high-resolution manometry.

BACKGROUND: Criteria for transient lower esophageal sphincter relaxations (TLESRs) are well-defined for Dentsleeve manometry. As high-resolution manometry (HRM) is now the gold standard to assess esophageal motility, our aim was to propose a consensus definition of TLESRs using HRM. METHODS: Postprandial esophageal HRM combined with impedance was performed in 10 patients with gastroesophageal reflux disease. Transient lower esophageal sphincter relaxations identification was performed by 17 experts using a Delphi process. Four investigators then characterized TLESR candidates that achieved 100% agreement (TLESR events) and those that achieved less than 25% agreement (non-events) after the third round. Logistic regression and decision tree analysis were used to define optimal diagnostic criteria. KEY RESULTS: All diagnostic criteria were more frequently encountered in the 57 TLESR events than in the 52 non-events. Crural diaphragm (CD) inhibition and LES relaxation duration >10 seconds had the highest predictive value to identify TLESR. Based on decision tree analysis, reflux on impedance, esophageal shortening, common cavity, upper esophageal sphincter relaxation without swallow and secondary peristalsis were alternate diagnostic criteria. CONCLUSION & INFERENCES: Using HRM, TLESR might be defined as LES relaxation occurring in absence of swallowing, lasting more than 10 seconds and associated with CD inhibition.

Randomized clinical trial of sacral nerve stimulation for refractory constipation.

BACKGROUND: Open studies have reported favourable results for sacral nerve stimulation in the treatment of refractory constipation. Here, its efficacy was assessed in a double-blind crossover RCT. METHODS: Patients with at least two of the following criteria were included: fewer than three bowel movements per week; straining to evacuate on more than 25 per cent of attempts; or sensation of incomplete evacuation on more than 25 per cent of occasions. Response to therapy was defined as at least three bowel movements per week and/or more than 50 per cent improvement in symptoms. Responders to an initial 3-week peripheral nerve evaluation were offered permanent implantation of a pulse generator and were assigned randomly in a crossover design to two 8-week intervals of active or sham stimulation. At the end of the two trial periods, the patients received active stimulation until the final evaluation at 1 year. RESULTS: Thirty-six patients (34 women; mean(s.d.) age 45(14) years) underwent peripheral nerve evaluation. Twenty responded and received a permanent stimulator. A positive response was observed in 12 of 20 and 11 of 20 patients after active and sham stimulation periods respectively (P = 0·746). Pain related to the device occurred in five patients and wound infection or haematoma in three, leading to definitive removal of the pulse generator in two patients. At 1 year, 11 of the 20 patients with an implanted device continued to respond. Stimulation had no significant effect on colonic transit time. CONCLUSION: These results do not support the recommendation of permanent implantation of a pulse generator in patients with refractory constipation who initially responded to temporary nerve stimulation. Registration number: NCT01629303 (http://www.clinicaltrials.gov).

Impact of Intragastric Balloon Before Laparoscopic Gastric Bypass on Patients with Super Obesity: a Randomized Multicenter Study.

BACKGROUND: Super obese patients are recommended to lose weight before bariatric surgery. The effect of intragastric balloon (IGB)-induced weight loss before laparoscopic gastric bypass (LGBP) has not been reported. The aim of this prospective randomized multicenter study was to compare the impact of preoperative 6-month IGB with standard medical care (SMC) in LGBP patients. METHODS: Patients with BMI >45 kg/m2 selected for LGBP were included and randomized to receive either SMC or IGB. After 6 months (M6), the IGB was removed and LGBP was performed in both groups. Postoperative follow-up period was 6 months (M12). The primary endpoint was the proportion of patients requiring ICU stay >24 h; secondary criteria were weight changes, operative time, hospitalization stay, and perioperative complications. RESULTS: Only 115 patients were included (BMI 54.3 ± 8.7 kg/m2), of which 55 underwent IGB insertion. The proportion of patients who stayed in ICU >24 h was similar in both groups (P = 0.87). At M6, weight loss was significantly greater in the IGB group than in the SMC group (P < 0.0001). Three severe complications occurred during IGB removal. Mean operative time for LGBP was similar in both groups (P = 0.49). Five patients had 1 or more surgical complications, all in the IGB group (P = 0.02). Both groups had similar hospitalization stay (P = 0.59) and weight loss at M12 (P = 0.31). CONCLUSION: IGB insertion before LGBP induced weight loss but did not improve the perioperative outcomes or affect postoperative weight loss.

Factors associated with nonresponse to proton pump inhibitors therapy in patients referred for esophageal pH-impedance monitoring.

Nonresponse to proton pump inhibitors (PPI) concerns up to 40% of patients treated for gastroesophageal reflux disease (GERD). Identifying predictive factors of nonresponse might help to optimize patients' treatment. The aim of this study was to determine clinical factors associated with nonresponse to PPI therapy in patients referred for pH-impedance monitoring. One hundred and sixty-eight consecutive patients (105 females, mean age 52 years, range 17-83) were included between October 2011 and May 2013. Before the realization of high-resolution manometry and 24-hour pH-impedance monitoring they completed a questionnaire including Rome III criteria for functional dyspepsia and irritable bowel syndrome (IBS). Comparisons between patients with and without PPI response were performed using chi-square or analysis of variance tests. One hundred and twenty-six patients (83%) were considered as PPI nonresponders and 26 (17%) as responders. No significant difference was observed for age and body mass index. No manometric and pH-impedance profiles were identified as associated with PPI response. The percentage of patients with functional dyspepsia and IBS was higher in PPI nonresponders patients than in responders (65.6% and 27.2%, respectively, vs. 38.5% and 7.7%, P = 0.01 and P = 0.03). This study confirms that functional digestive disorders are more frequent in patients with persistent GERD symptoms on PPI and they might be indicative of nonresponse to PPI therapy.

Extensive preoperative workup in diffuse esophageal leiomyomatosis associated with Alport syndrome influences surgical treatment: A case report.

INTRODUCTION: Diffuse esophageal leiomyomatosis is a rare disease. Misdiagnosis is frequent and previous surgeries can complicate surgical management. The only treatment described for severe symptomatic cases is esophagectomy. PRESENTATION OF CASE: We describe a case of diffuse esophageal leiomyomatosis associated with Alport syndrome in a 21 year-old female where endoscopic ultrasonography (EUS) with concomitant fluoroscopy and 3D-gastric computed tomography (3D-GCT) modified surgical management. DISCUSSION: The diagnosis of diffuse esophageal leiomyomatosis is difficult but can be greatly facilitated by extensive endoscopic and radiologic workup. Esophagectomy should only be entertained after complete anatomic mapping of the lesions, especially after previous surgeries. CONCLUSION: EUS and 3D-GCT should strongly be considered as part of routine preoperative workup in these patients.

Inter-observer agreement for diagnostic classification of esophageal motility disorders defined in high-resolution manometry.

High-resolution esophageal manometry (HRM) is a recent development used in the evaluation of esophageal function. Our aim was to assess the inter-observer agreement for diagnosis of esophageal motility disorders using this technology. Practitioners registered on the HRM Working Group website were invited to review and classify (i) 147 individual water swallows and (ii) 40 diagnostic studies comprising 10 swallows using a drop-down menu that followed the Chicago Classification system. Data were presented using a standardized format with pressure contours without a summary of HRM metrics. The sequence of swallows was fixed for each user but randomized between users to avoid sequence bias. Participants were blinded to other entries. (i) Individual swallows were assessed by 18 practitioners (13 institutions). Consensus agreement (≤ 2/18 dissenters) was present for most cases of normal peristalsis and achalasia but not for cases of peristaltic dysmotility. (ii) Diagnostic studies were assessed by 36 practitioners (28 institutions). Overall inter-observer agreement was 'moderate' (kappa 0.51) being 'substantial' (kappa > 0.7) for achalasia type I/II and no lower than 'fair-moderate' (kappa >0.34) for any diagnosis. Overall agreement was somewhat higher among those that had performed >400 studies (n = 9; kappa 0.55) and 'substantial' among experts involved in development of the Chicago Classification system (n = 4; kappa 0.66). This prospective, randomized, and blinded study reports an acceptable level of inter-observer agreement for HRM diagnoses across the full spectrum of esophageal motility disorders for a large group of clinicians working in a range of medical institutions. Suboptimal agreement for diagnosis of peristaltic motility disorders highlights contribution of objective HRM metrics.

Botulinum toxin injection for hypercontractile or spastic esophageal motility disorders: may high-resolution manometry help to select cases?

Endoscopic injections of botulinum toxin in the cardia or distal esophagus have been advocated to treat achalasia and spastic esophageal motility disorders. We conducted a retrospective study to evaluate whether manometric diagnosis using the Chicago classification in high-resolution manometry (HRM) would be predictive of the clinical response. Charts of patients with spastic and hypertensive motility disorders diagnosed with HRM and treated with botulinum toxin were retrospectively reviewed at two centers. HRM recordings were systematically reanalyzed, and a patient's phone survey was conducted. Forty-five patients treated between 2008 and 2013 were included. Most patients had achalasia type 3 (22 cases). Other diagnoses were jackhammer esophagus (8 cases), distal esophageal spasm (7 cases), esophagogastric junction outflow obstruction (5 cases), nutcracker esophagus (1 case), and 2 unclassified cases. Botulinum toxin injections were performed into the cardia only in 9 cases, into the wall of the distal esophagus in 19 cases, and in both locations (cardia and distal esophagus) in 17 cases. No complication occurred in 31 cases. Chest pain was noticed for less than 7 days in 13 cases. One death related to mediastinitis occurred 3 weeks after botulinum toxin injection. Efficacy was assessed in 42 patients: 71% were significantly improved 2 months after botulinum toxin, and 57% remained satisfied for more than 6 months. No clear difference was observed in terms of response according to manometric diagnosis; however, type 3 achalasia previously dilated and with normal integrated relaxation pressure (4s-integrated relaxation pressure < 15 mmHg) had the worst outcome: none of these patients responded to the endoscopic injection of botulinum toxin. Endoscopic injections of botulinum toxin may be effective in some patients with spastic or hypercontractile esophageal motility disorders. The manometric Chicago classification diagnosis does not seem to predict the results. Prospective randomized trials are required to identify patients most likely to benefit from esophageal botulinum toxin treatment.

Randomized clinical trial: effect of the 5-HT4 receptor agonist revexepride on reflux parameters in patients with persistent reflux symptoms despite PPI treatment.

BACKGROUND: Approximately, 20-30% of patients with gastro-esophageal reflux disease (GERD) experience persistent symptoms despite treatment with proton pump inhibitors (PPIs). These patients may have underlying dysmotility; therefore, targeting gastric motor dysfunction in addition to acid inhibition may represent a new therapeutic avenue. The aim of this study was to assess the pharmacodynamic effect of the prokinetic agent revexepride (a 5-HT4 receptor agonist) in patients with GERD who have persistent symptoms despite treatment with a PPI. METHODS: This was a phase II, exploratory, multicenter, randomized, placebo-controlled, double-blind, parallel-group study in patients with GERD who experienced persistent symptoms while taking a stable dose of PPIs (ClinicalTrials.gov identifier: NCT01370863). Patients were randomized to either revexepride (0.5 mg, three times daily) or matching placebo for 4 weeks. Reflux events and associated characteristics were assessed by pH/impedance monitoring and disease symptoms were assessed using electronic diaries and questionnaires. KEY RESULTS: In total, 67 patients were enrolled in the study. There were no significant differences between study arms in the number, the mean proximal extent or the bolus clearance times of liquid-containing reflux events. Changes from baseline in the number of heartburn, regurgitation, and other symptom events were minimal for each treatment group and no clear trends were observed. CONCLUSIONS & INFERENCES: No clear differences were seen in reflux parameters between the placebo and revexepride groups.

Oesophageal function assessed by high-resolution manometry in patients with diabetes and inadequate glycaemic control.

AIMS: To describe oesophageal function in people with diabetes and poor glycaemic control using oesophageal high-resolution manometry and to compare the result between control subjects and patients with gastro-oesophageal reflux disease. METHODS: The results of oesophageal high-resolution manometry and a gastric emptying test were reviewed in 20 patients with diabetes. The high-resolution manometry protocol consisted of 5-ml swallows of water and multiple swallows of water. Oesophageal motility disorders were classified according to the Chicago classification system. The occurence of multiphasic contractions and intragastric and intrabolus pressures were measured. High-resolution manometry results were compared between 10 control subjects and 20 patients with gastro-oesophageal reflux disease. Data were expressed as medians and compared using Mann-Whitney and chi-squared tests. RESULTS: Oesophageal motility disorders were similarly distributed between the groups. Multiphasic contractions occurred more frequently in patients with diabetes than in those with gastro-oesophageal reflux disease (60 vs 20% per patient; P<0.01) and were not observed in control subjects. Gastric emptying was delayed in six patients with diabetes and did not correlate with symptoms or oesophageal motility disorders. Intrabolus pressure was higher in patients with diabetes and gastroparesis than in those without (17 vs 10 mmHg; P=0.02) and correlated with intragastric pressure (r=0.46, P<0.01). During multiple swallows of water, oesophageal contractile activity was incompletely inhibited in 83% of patients with diabetes and gastroparesis vs 9% without (P<0.01). Oesophageal function and gastric emptying were not influenced by fasting glycaemia. CONCLUSIONS: Patients with gastroparesis might present with impaired inhibition of contractile activity during multiple swallows of water. Increased intrabolus pressure is suggestive of delayed oesophageal clearance as a consequence of gastroparesis.

Transcutaneous electrical tibial nerve stimulation in the treatment of fecal incontinence: a randomized trial (CONSORT 1a).

OBJECTIVES: The objective of this study was to show that although transcutaneous electrical tibial nerve stimulation (TENS) is being increasingly used to treat fecal incontinence (FI), its efficacy has never been proved using controlled trials. METHODS: In this randomized, double-blind, sham-controlled trial, 144 patients aged 30-82 years from nine centers were randomly assigned to receive either active or sham stimulations for 3 months. The primary end point was the response to treatment based on the number of incontinence and urgency episodes. Secondary end points were severity scores, quality of life scores, delay to postpone defecation, patient self-assessment of treatment efficacy, physician assessment of TENS efficacy, anorectal manometry, and adverse events. RESULTS: No statistically significant difference was seen between active and sham TENS in terms of an improvement in the median number of FI/urgency episodes per week. Thirty-four patients (47%) who received the active TENS treatment exhibited a >30% decrease in the FI severity score compared with 19 patients (27%) who received the sham treatment (odds ratio 2.4, 95% confidence interval 1.1-5.1, P=0.02). No differences in delay to postpone defecation, patient self-assessment of treatment efficacy, or anorectal manometry were seen between the two groups. The evaluating physicians rated the active stimulations as more effective than the sham stimulations (P=0.01). One minor therapy-related adverse event was observed (1.5%) (see Supplementary Consort 1b). CONCLUSIONS: We failed to demonstrate any benefit of TENS on our primary end-point.

Achalasia-like disorder after laparoscopic adjustable gastric banding: a reversible side effect?

Literature data concerning the effect of laparoscopic adjustable gastric banding (LAGB) on esophageal motility are conflicting. Achalasia-like disorder involving the absence of esophageal peristalsis and impaired esophago-gastric junction (EGJ) is probably under-estimated and can result in failure and band removal. The aim of our study was to focus on cases of achalasia-like disorder and study its evolution after band deflating or removal. LAGB patients with food intolerance and whose esophageal manometry confirmed dysmotility were selected from our database. Achalasia-like disorder was defined as the absence of esophageal peristalsis (< 20% contraction waves) with impairment of EGJ relaxation. Manometric control was performed after removal or band deflating; functional results were assessed. Eleven patients among 20 (55%) with esophageal motility disorders (EMD) fitted the manometric criteria of achalasia-like disorder with a mean EGJ resting pressure of 32.1 cmH(2)O and a EGJ relaxation pressure of 24.2. Nine patients out of 11 underwent band removal which resulted in the resolution of their symptoms. The other two underwent band deflation. Manometric control after band removal showed both a decrease in resting and relaxation EGJ pressures (mean of 9.5 and 6.5 cmH(2)O) and a recovery of wave contractions in 87.5% of cases. Four patients underwent revision surgery due to weight regain with a successful outcome. Achalasia-like disorder is a manometric diagnosis and accounts for a significant part of symptomatic EMD after LAGB. It often results in band removal, allowing some reversibility of the disorders.
