Evaluating Efficacy Of Functional Luminal Imaging Probe In Preoperative Evaluation For Antireflux Procedures

Introduction: The COVID-19 pandemic caused significant decreases in outpatient procedures, many of which are required before to antireflux operation (ARS). The purpose of this study was to add functional luminal imaging probe (FLIP) to esophagogastroduodenoscopy (EGD) and esophageal pH monitoring to assess its utility in decreasing the need for follow up studies in patients being evaluated for ARS. Method(s): Retrospective observational study was performed on 81 patients being evaluated for GERD who underwent EGD, pH monitoring, and FLIP. Data collected included average distensibility index (DI) at 60 mL, presence of repetitive anterograde or retrograde contractions, hiatal hernia dimensions, pathology results, pH data, and need for follow-up testing. Result(s): Based on FLIP results, HRM was recommended in 35 patients (43.2%). This included 14 patients with DI suggestive of significant esophagogastric junction outflow obstruction, eight of whom completed HRM with four confirmed as achalasia. FLIP results were suspicious for eosinophilic esophagitis (EoE) in four patients of which one was confirmed as EoE on biopsy. Gastric emptying study was felt to be necessary for 11 patients before to ARS. Conclusion(s): FLIP identified patients with possible alternative pathologies including achalasia and EoE that would otherwise be a contraindication to ARS. FLIP at the time of EGD and pH monitoring is useful as it guides the clinical decision on need for additional outpatient procedures, which may be difficult to obtain in pandemic conditions. FLIP was effective at reducing the requirements for further follow-up testing in the majority of patients being evaluated for potential ARS.

Acute-Onset Achalasia Following a Recent COVID-19 Infection: A Case Report.

Achalasia is a rare esophageal motility disorder that leads to dysphagia, regurgitation, and several other symptoms. While the etiology of achalasia is not completely understood, studies have suggested an immune reaction to viral infections, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as a potential cause. Here, we present a case report of a previously healthy 38-year-old male who presented to the emergency room with severe shortness of breath, recurrent vomiting, and dry cough, that had progressively worsened over five days. The patient was diagnosed with coronavirus disease 2019 (COVID-19), and a chest CT also revealed prominent features of achalasia with a markedly dilated esophagus and areas of narrowing at the distal esophagus. The initial management of the patient included IV fluids, antibiotics, anticholinergics, and corticosteroid inhalers which improved his symptoms. This case report highlights the importance of considering the acute-onset of achalasia in COVID-19 patients and the need for further research on the potential association between SARS-CoV-2 and achalasia.

Myasthenia gravis with achalasia secondary to thymoma: a case report and literature review.

Background: Myasthenia gravis is an autoimmune neuromuscular junction disorder characterized by fatigable muscle weakness and autoantibodies. Frequent associations exist between myasthenia gravis and thymic abnormalities, including hyperplasia and thymoma. Several autoimmune illnesses have been identified to be associated with thymoma; however, a few case reports have linked thymoma and achalasia, and the underlying mechanism is unknown. Case report: A 43-year-old man with thymoma-associated myasthenia gravis presented with dysphagia that was refractory to conventional treatment of myasthenia gravis. This dysphagia was challenging to diagnose even after multiple gastroenterology consults and upper endoscopy. The diagnosis of achalasia type II was established after a comprehensive evaluation, including upper endoscopy, barium swallow, and high-resolution esophageal manometry. The patient underwent elective pneumatic balloon dilatation, which successfully alleviated his dysphagia. Conclusion: This case confirmed the association between myasthenia gravis secondary to thymoma and achalasia and showed how the diagnosis of achalasia was challenging. Awareness of this association is crucial for early diagnosis and treatment, improving affected patients' quality of life.

Esophageal Squamous Cell Carcinoma: An Unfavorable Complication of Achalasia

Introduction: Achalasia is a motility disorder of the esophagus characterized by impaired relaxation of the lower esophageal sphincter and loss of peristalsis in the distal esophagus. It is a rare condition with an annual incidence of 0.5-1.2 per 100,000 individuals. The etiology of primary achalasia is unknown, however secondary achalasia can be attributed to malignancy, infections or systemic diseases such as amyloidosis. An infrequent complication of achalasia is esophageal squamous cell carcinoma which has a prevalence of 26 in every 1,000 cases. We present a case of interval locoregionally advanced esophageal squamous cell carcinoma only 2 years after a normal upper endoscopy. Case Description/Methods: A 67-year-old female with known achalasia and previous pneumatic dilation in her 30s presented to our outpatient clinic in 2019 with complaints of worsening chronic dysphagia. EGD was performed which revealed a significantly dilated esophagus with candida esophagitis. Despite completing antifungal therapy, she continued to experience dysphagia to solids and liquids. Barium swallow demonstrated absent peristalsis with pooling of contrast within the esophagus. High-Resolution Manometry testing demonstrated absent peristalsis. She opted for surgical myotomy, however due to COVID restrictions, the procedure was delayed. Repeat EGD was performed in 2022 for pre-surgical evaluation and showed a large obstructing friable esophageal mass in the lower third of the esophagus. Pathology was consistent with invasive poorly differentiated squamous cell carcinoma. PET scan showed locoregional disease with FDG-avid esophageal and gastrohepatic node lesions. She was started on chemoradiation with Paclitaxel and Carboplatin (Figure). Discussion(s): The risk of esophageal squamous cell carcinoma in achalasia has significantly increased with incidence of approximately 1 in 300 patients. The presumed mechanism of malignancy in achalasia is poor emptying resulting in food stasis, bacterial overgrowth and inflammation leading to dysplasia and development of carcinoma. Given the relatively low incidence, there are currently no guidelines on routine endoscopic screening to assess for malignancy in patients with achalasia. Survival rates are poor as patients are often diagnosed at advanced stages. This case aims to illustrate the importance and need for interval screening in individuals with long standing achalasia to improve outcomes.

Laparoscopic Paraesophageal Hernia (PEH) Repair, Roux-en-Y Gastric Bypass, and Per Oral Endoscopic Myotomy (POEM) in a Patient with Achalasia After Sleeve Gastrectomy.

BACKGROUND: GERD and Achalasia are two known complications after sleeve gastrectomy. Treatment towards each of these complications varies and requires a tailored approach. METHODS: We present a 55-year-old female with class II obesity and a previous history of sleeve gastrectomy who developed significant gastroesophageal reflux disease refractory to medical management. After a covid infection in fall of 2020, she began to report new symptoms of dysphagia that progressed from solids to liquids. She underwent extensive workup including upper endoscopy, upper GI barium swallow, manometry, pH impedence, and EndoFlip leading to a diagnosis of Achalasia type II as well as a paraesophageal hernia. RESULTS: Given these findings, she underwent a combined paraesophageal hernia repair with conversion of sleeve gastrectomy to Roux-en-Y gastric diversion and an intra-operative peroral endoscopic myotomy. Intraoperatively, she was noted to have significant lower abdominal adhesions leading to performing the Roux-en-Y reconstruction through a supramesocolic defect in a retrocolic fashion. CONCLUSIONS: While the development of heartburn and achalasia after sleeve gastrectomy is rare, it requires interventions dedicated towards each etiology. This case demonstrates treatment of both these symptoms is feasible in a single operation.

Is the Sars-CoV-2 virus a possible trigger agent for the development of achalasia?

BACKGROUND: Achalasia is an autoimmune disease whose probable causal agent is a neurotropic virus that chronically infects the myenteric plexus of the esophagus and induces the disease in a genetically susceptible host. The association between achalasia and coronaviruses has not been reported. AIMS: To evaluate the presence of the SARS-CoV-2 virus, the ACE2 expression, the tissue architecture, and immune response in the lower esophageal sphincter muscle (LESm) of achalasia patients who posteriorly had SARS-CoV-2 (achalasia-COVID-19) infection before laparoscopic Heller myotomy (LHM) and compare the findings with type II achalasia patients and transplant donors (controls) without COVID-19. METHODS: The LESm of 7 achalasia-COVID-19 patients (diagnosed by PCR), ten achalasia patients, and ten controls without COVID-19 were included. The presence of the virus was evaluated by in situ PCR and immunohistochemistry. ACE2 receptor expression and effector CD4 T cell and regulatory subsets were determined by immunohistochemistry. KEY RESULTS: Coronavirus was detected in 6/7 patients-COVID-19. The SARS-CoV-2 was undetectable in the LESm of the achalasia patients and controls. ACE2 receptor was expressed in all the patients and controls. One patient developed achalasia type II post-COVID-19. The percentage of Th22/Th17/Th1/pDCreg was higher in achalasia and achalasia-COVID-19 pre-HLM vs. controls. The Th2/Treg/Breg cell percentages were higher only in achalasia vs. controls. CONCLUSION & INFERENCES: SARS-CoV2 and its receptor expression in the LESm of achalasia patients who posteriorly had COVID-19 but not in the controls suggests that it could affect the myenteric plexus. Unlike achalasia, patients-COVID-19 have an imbalance between effector CD4 T cells and the regulatory mechanisms.

Influence of Anxiety and Depression on the Symptoms of Achalasia Patients: A Retrospective Cohort Study in China during COVID-19.

BACKGROUND: Idiopathic achalasia (AC) may be affected by anxiety and/or depression; however, reliable evidence is still lacking. The present retrospective cohort study aimed to explore the influence of psycho-mental factors on the severity of AC. METHODS: All patients in the AC database of the Tianjin Medical University General Hospital from 2012 to 2020 were divided into two subgroups, intervention (n = 202) and medication (n = 84), according to previous treatments. Healthy people (n = 300) who underwent gastrointestinal endoscopy comprised the control group. The severity of symptoms and the anxiety and depression score of AC patients and controls were monitored by telephone and compared before and during COVID-19. In addition, the factors of AC symptoms during the COVID-19 were discussed by multiple linear regression. RESULTS: During COVID-19, the anxiety and depression levels of AC patients and healthy individuals were deteriorated. For AC patients, before and after COVID-19, symptoms, anxiety, and depression scores in the medication group were more serious than those in the intervention group. Furthermore, previous therapy, depression, and gender were found to be significantly related to the severity of AC symptoms during COVID-19. CONCLUSIONS: The outbreak of COVID-19 made AC patients and healthy people anxious and depressed. Depression rather than anxiety might worsen the AC symptoms. Interventional therapy might protect AC patients against psychological abnormalities during COVID-19.

The first report of a known 4A syndrome patient with suspected manifestations of COVID-19, what was the final outcome?

The present study was performed on a 24-year-old Iranian man referred to Hospital with suspected symptoms of COVID-19, including fever, weakness, and cough. According to medical history, he had Alacrima, esophageal Achalasia, and adrenal insufficiency from childhood. Based on medical records and clinical examinations, the physician suspected 3A syndrome in the patient and requested further examination for MRI, CXR, and COVID-19 RT-PCR test. The result of the COVID-19 RT-PCR test was negative the next day. The patient's CXR showed ground-glass opacity (GGO) and pulmonary fibrosis. Based on images and MRI reports, severe posterior cortical atrophy disproportionate to chronological age and bilateral atrophy of the lacrimal gland were reported. After reviewing and summarizing the records, history, examinations, and Paraclinical tests, the patient was identified as a case of 4A syndrome.

Effectiveness of Telehealth in Meeting Needs of Benign Foregut Patients

INTRODUCTION: Telehealth visits became a staple in surgical practice in the setting of COVID-19. The objective of this study is to assess benign foregut patient satisfaction and perceived cost savings with use of telehealth visits. METHOD(S): This is a single academic center prospective study of benign foregut patients evaluated for routine postoperative care by a telehealth visit over a 1-year period. Patients who agreed to participate completed a survey assessing their experience with telehealth. RESULT(S): There were 19 patients (13 phone, 6 virtual) ages 21 to 74 years (male:female 5:14) included. A total of 84% underwent hiatal hernia repair, and others underwent operation for achalasia, feeding access, gastric pacemaker, and choledocholithiasis (average length-ofstay 3.5 days, range 0 to 13). The majority (84.2%) reported a high overall satisfaction score (>4/5, range 3 to 5). Of these patients, 94.7% agreed/strongly agreed that their provider was able to adequately assess their problem, that their concerns were addressed, and that they would participate in future telehealth visits. The average time to drive to a hypothetical in-person appointment was 180 minutes (range 20 to 480 minutes). When comparing telehealth with hypothetical in-person visits, no patients had to take time off work for telehealth vs 15.8% would for in-person visits. A total of 21% would need a family member to take time off for in-person visit;of those, 75% would have suffered wage loss;36.8% and 42.1% would require overnight accommodation and meal costs for hypothetical in-person visits, respectively (travel time range 180 to 480 minutes). CONCLUSION(S): Postoperative benign foregut patients were very satisfied with telehealth care with time and cost-saving benefits reported for those traveling long distances for in-person visits.

Laparoscopic Paraoesophageal Hernia, Gastric Bypass and Peroral Endoscopic Myotomy in a patient with Achalasia and Gastroesophageal reflux after Sleeve Gastrectomy

Daniel Slack Charlotte NC1, Paul Colavita Charlotte NC1, Abdelrahman Nimeri Charlotte NC1 Carolinas Medical Center, Atrium Health1 We present a 55-year-old female with class II obesity and a previous history of sleeve gastrectomy who developed significant gastroesophageal reflux disease refractory to medical management. After a covid infection in fall of 2020 she began to report new symptoms of dysphagia that progressed from solids to liquids. She underwent extensive workup including upper endoscopy, upper GI barium swallow, manometry, pH impedence and EndoFlip leading to a diagnosis of Achalasia type II as well as a paraesophageal hernia. Given these findings she underwent a combined paraesophageal hernia repair with conversion of sleeve gastrectomy to Roux-en-Y gastric diversion and an intra-operative Peroral Endoscopic Myotomy. Intra-operatively she was noted to have significant lower abdominal adhesions leading to performing the Roux-en-Y reconstruction through a supramesocolic defect in a retrocolic fashion. The patient tolerated the procedure well and recovered with improvement of both her reflux and achalasia.

Perception of the COVID-19 pandemic in patients with achalasia and its impact on gastrointestinal symptoms: a proof-of-concept study.

Background: Currently, no data are available on COVID-19 pandemic perception in patients with achalasia. We evaluated how the COVID-19 lockdown was perceived by these patients and its impact on their upper gastrointestinal symptoms. Methods: COVID-19 perception was assessed in 64 patients with achalasia using a previously published survey. Upper gastrointestinal symptoms were assessed using a standardized questionnaire and the results were compared to those obtained before the COVID-19 pandemic. All questionnaires were administered by telephone/video calls during the second Italian lockdown. Results: Fifty-one patients (79.7%) responded to the survey. For the question "On a 0-100 scale, how worried are you about the COVID-19 pandemic?" the mean score was 72.8±27.1, and 64.7% of patients with achalasia gave a score >60 on a visual analog scale of 0-100. In addition, those who considered themselves more vulnerable or anxious about contracting the infection than the general population, showed a significantly higher score for COVID-19 fear compared to those who felt less vulnerable or anxious (79.7±27.6 vs. 62.5±23.6, P=0.027; 80.9±19.6 vs. 57.1±33.1, P=0.002, respectively). The selected patients (n=29), who had not undergone any change in medical/surgical treatment for at least one year before the COVID-19 pandemic, had a significant worsening of the intensity-frequency score of regurgitation, heartburn, odynophagia, water brash, and epigastric burning during the lockdown (P<0.05). Finally, 75% of the patients were very interested in using Telemedicine. Conclusions: The COVID-19 lockdown had a significant impact on the psychological aspects and upper gastrointestinal symptoms of patients with achalasia. Telemedicine might represent a follow-up strategy.

[Features and results of minimally invasive treatment of recurrent achalasia]. / Osobennosti i rezul'taty maloinvazivnogo lecheniya retsidiva akhalazii kardii.

OBJECTIVE: To evaluate the early and long-term postoperative outcomes in patients with recurrent achalasia, as well as the main features of surgical treatment. MATERIAL AND METHODS: There were 7 patients (4 men and 3 women) with recurrent achalasia. Mean age of patients was 42.3±13.5 years, body mass index - 22.7±3.3 kg/m2. Physiological status ASA grade 1-3 was observed in all patients. Concomitant diseases were diagnosed in 5 (71.4%) cases. Six (85.7%) patients underwent laparoscopic Heller cardiomyotomy with Dor fundoplication. Peroral endoscopic myotomy (POEM) was performed in 1 (14.3%) patient. Mean preoperative Eckardt score was 10.7±1.4 points, mean GERD-HRQL score - 42.7±6.4 points. According to preoperative radiography, 5 (71.4%) patients had achalasia stage III, 2 (28.6%) ones - stage IV. RESULTS: All patients underwent laparoscopic Heller esophagocardiomyotomy with anterior Dor fundoplication and posterior partial fundoplication with posterior cruroraphy. Intraoperative complications (perforation of esophageal mucosa) occurred in 3 (42.9%) patients. Mean surgery time was 130±56 min, mean blood loss - 37 ml (35-205 ml), mean hospital-stay - 11.3±7.7 days. Postoperative complications Clavien-Dindo grade 3-4 were detected in 1 (14.3%) patient. One patient was diagnosed with bilateral pneumonia (SARS-Cov-2 infection) in 4 postoperative days. Median postoperative follow-up period was 22 months. Mean BMI in 6 months after surgery was 25.3±3.1 kg/m2, mean Eckardt score - 2.1±0.7 points, mean GERD-HRQL score - 3.3±0.9 points. CONCLUSION: Our data confirm the effectiveness and safety of the modified laparoscopic Heller procedure with Dor fundoplication as the main method for recurrent achalasia.

INCREASED BURDEN OF SWALLOWING DISORDERS DURING THE COVID-19 PANDEMIC: A HOSPITAL SYSTEM-WIDE AUDIT

BACKGROUND: The indirect health impact of COVID-19 caused by delayed access to care or deferred medical procedures is yet to be fully appreciated. METHODS: We conducted a hospital system-wide audit of all inpatient gastrointestinal (GI) consults performed during the lockdown phase (3/23/2020 – 5/10/2020, n = 558) and the reopening phase (6/1/2020 –7/19/2020, n = 713) of the pandemic and compared against data from 2019 in order to discover any changes in disease burdens. GI diagnoses were derived from the patients' discharge summaries and verified by an independent review of the associated GI consult notes. RESULTS: The volume of inpatient consults was reduced by 27.7% during the lockdown phase compared to the same period in 2019. Yet, the proportion of consults for swallowing disorders (food impaction or chronic dysphagia from eosinophilic esophagitis or achalasia) was increased by 50.9% (p = 0.04). Coincidentally, all outpatient esophageal motility study or elective endoscopic dilation procedures at our hospital system were post-poned during this phase. While the volume of consults was restored during the reopening phase to 101% of that of the same period in 2019. The proportion of consults for swallowing disorders remained elevated by 47.7% (p = 0.02). In comparison, there was no significant change in the proportions of consults for foreign/caustic substance ingestion, inflammatory bowel diseases, or gastrointestinal bleeding during either the lockdown phase or the reopening phase. CONCLUSIONS: There was a significant surge in the demand for inpatient consults for swallowing disorders following the onset of the COVID-19 pandemic, coinciding with the postponement of elective endoscopic procedures. Resources should be allocated to manage patients with underlying esophageal motility disorders more effectively as the pan-demic continues.

Impact of the COVID-19 pandemic on endoscopic cancer detection at a single-centre in the UK

Introduction Endoscopy services were paused during the first wave of the COVID-19 pandemic between March - April 2020. Endoscopy resumed in May 2020 at a reduced productivity alongside early clinical triage in an effort to use resources responsibly. We assessed whether our reduced service led to reductions in gastrointestinal (GI) cancer detection. We assessed differences in the choice of initial investigation, clinical triage and referral to endoscopy time among GI cancers diagnosed via the suspected GI cancer referral pathway. Methods GI cancer diagnoses were reviewed retrospectively over a seven month period (Mar-Oct 2020). Inclusion criteria were patients coded with a new diagnosis of GI cancer. The volume of endoscopic procedures performed was assessed using our endoscopy reporting software. Results were compared to the equivalent time period in 2019. Differences in time to endoscopy (days) were evaluated with a two-sample unpaired t-test. Results There was a 28.5% reduction in GI cancer diagnoses in 2020 (Mar-Oct) compared to 2019 (191 vs 267), with a 27.1% reduction in GI cancers diagnosed via endoscopic procedures (132 vs 181). There was a 42.7% reduction in endoscopic procedures in 2020 (Mar-Oct) compared to 2019 (6977 vs 12186). In terms of referrals for suspected GI cancers from GPs, there was a 30% reduction (3188 vs 4579). In 2020 (Mar-Oct), among cancers diagnosed via endoscopic procedures on the suspected GI cancer pathway, 40 of 68 (58.8%) patients had imaging as their first investigation (n=5 Barium swallow, n=13 CT abdomen, n=22 CT colonography) compared to 21 of 81 (25.9%) patients in 2019 (n=11 CT abdomen, n=9 CT colonography). Following the start of clinical triage (May-Oct 2020), 36 of 54 (67%) patients were triaged as 'very urgent'. 17 of 54 (31%) patients were triaged as 'urgent'. 1 patient was not prioritised as their barium swallow suggested a diagnosis of achalasia which was later found to be an oesophageal malignancy (referral to endoscopy 95 days). There was no significant difference in referral to endoscopy time in 2020 (Mar-Oct) [mean 45 days, SD 40.2] compared to 2019 [mean 41.6 days, SD 26.7] (mean difference 3.4 days p=0.55). Conclusions The COVID-19 pandemic has led to a 28.5% reduction in GI cancer diagnoses. This worrying reduction in cancer detection will need to be ameliorated by an increase in endoscopy capacity. Radiological investigations were utilised more during this period to assess suspected GI cancer referrals. 98% of cancer patients were appropriately prioritised as very urgent or urgent based on clinical triage, and radiological investigations aided in triage. There was no significant difference in referral to endoscopy time. We highlight that achalasia diagnosed on barium swallow should always visualised directly, even with curtailed endoscopy capacity.

Impact of the COVID-19 pandemic on high-resolution manometry and peroral endoscopic myotomy for esophageal motility disorder in Japan.

AIM: To elucidate the impact of the coronavirus disease 2019 (COVID-19) on the practice of high-resolution manometry (HRM) and peroral endoscopic myotomy (POEM) in Japan. METHODS: We utilized a large-scale database involving 14 high-volume centers in Japan to investigate changes in the numbers of HRM and POEM procedures performed and outcomes of POEM between 2019 and 2020. A questionnaire survey was also conducted to analyze pandemic-associated changes in the HRM and POEM protocols. RESULTS: Compared to that in 2019, the number of HRM and POEM procedures decreased by 17.2% (1587-1314) and 20.9% (630-498), respectively. These declines were prominent during the state of emergency from April to May 2020, particularly in pandemic areas. HRM and POEM in nonpandemic areas were relatively unaffected. From 2019 to 2020, there was a 0.4% (254-248) decrease in POEM cases within the prefecture, but the number outside the prefecture decreased by 33.6% (372-247). During the pandemic, the safety and efficacy of POEM were maintained. The implementation of personal protective equipment (PPE) measures varied among facilities, and PPE for POEM was relatively insufficient compared to that for HRM. CONCLUSION: The COVID-19 pandemic influenced HRM and POEM practices in Japan. It is necessary to establish a sufficient system for HRM and POEM in each hospital as well as countrywide to overcome the effects of the pandemic.

Detection of cytokine storm in patients with achalasia using ELISA.

Esophageal achalasia is characterized by abnormal peristaltic movements of the esophageal body and impaired relaxation of the lower esophageal sphincter (LES). However, its etiology remains unknown. In our previous study, it was shown that in the LES of patients with achalasia, hsv1-miR-H1 was overexpressed, ATG16L1 expression was downregulated and interleukin (IL)-1ß levels were upregulated. However, systemic features were not evaluated. Herein, the plasma cytokine levels in patients with achalasia were determined. Plasma was collected from patients at Nagasaki University Hospital between February 2013 and March 2016, both before and after peroral endoscopic myotomy (POEM). Cytokine analysis was performed using plasma collected from 10 healthy individuals (control group) and 12 patients with achalasia using the Bio-Plex Pro™ Human Cytokine 27-plex assay kit. The levels of IL-17, IL-1ß, C-C motif chemokine ligand 2, IL-4, IL-5, IL-1ra, IL-7, IL-12, interferon-γ, IL-2, fibroblast growth factor-2, colony-stimulating factor (CSF)2 and CSF3 were significantly higher in patients with achalasia compared with the control subjects. However, the levels did not differ between plasma samples collected before and after POEM. Thus, the occurrence of a cytokine storm was confirmed in the patients with achalasia.
