Achalasia in pregnancy.

Achalasia is characterised by incomplete relaxation of the lower oesophageal sphincter and aberrant oesophageal peristaltic activity resulting in impaired oesophageal emptying. This rare condition in pregnancy is unique as both the disease and its treatment are associated with fetomaternal risks and complications. A woman in her early 30s, gravida 3 para 2 at 35 weeks' pregnancy with suspected oesophageal achalasia, presented with shortness of breath, cough and fever following frequent bouts of vomiting and fluid regurgitation. She was diagnosed with aspiration pneumonia complicated by severe metabolic acidosis, malnutrition syndrome and fetal growth restriction. Following stabilisation of the acute clinical problems, delivery was expedited via caesarean section. Postpartum endoscopy confirmed the diagnosis of achalasia as per initial suspicion. Definitive surgery was performed several months later after optimisation of the patient's nutritional status. This case illustrates the life-threatening complications of achalasia in pregnancy.

[Achalasia cardiae causing megaesophagus: "From the beginnings to the resolution"]. / Megaoesophagust okozó achalasia cardiae: "a kezdetektol a megoldásig".

Achalasia cardiae miatt az elso oesophago-cardia myotomiát több mint száz évvel ezelott Ernst Heller német sebész végezte. Az achalasiás betegek a mai napig ettol a beavatkozástól várják panaszaik megszunését. Az achalasia napjainkban is chronikus, progresszív betegség, aminek oki kezelését nem ismerjük, a gyógyítására, a panaszok enyhítésére gyógyszeres (calcium csatorna blokkolók stb.), endoscopos (botulinum toxin inj., ballonos tágítás, per oralis endoscopos myotomiát [POEM]) és sebészi (laparoscopos, thoracoscopos myotomia) kezeléseket váltakozó sikerrel alkalmazunk.A betegség progresszivitása miatt a betegek 5%-ánál a nyelésképtelenségig fokozódó dysphagia, megaoesophagus alakul ki, megoldására mutéti beavatkozás válik szükségessé. A muködésképtelen nyelocso eltávolítása és pótlása kiterjedt, nem elhanyagolható morbiditással és mortalitással járó beavatkozás. Közleményünkben egy 45 éves nobeteg kórtörténetét, az általunk alkalmazott mutéti beavatkozást ismertetjük. A beteg a mutét óta panaszmentes.

Abnormal performance of peroral endoscopic myotomy (POEM): a case misdiagnosed as achalasia of cardia.

BACKGROUND: Pseudoachalasia is a rare disease that behaves similarly to achalasia (AC), making it sometimes difficult to differentiate. CASE PRESENTATION: We report a case of 49-year-old male with adenocarcinoma of the gastroesophageal junction misdiagnosed as achalasia. No obvious abnormalities were found in his initial examinations including upper digestive endoscopy, upper gastrointestinal imaging and chest computed tomography (CT). During the subsequent introduced-peroral endoscopic myotomy (POEM), it was found that the mucosal layer and the muscular layer had severe adhesion, which did not receive much attention, delayed the clear diagnosis and effect treatment, and ultimately led to a poor prognosis for the patient. CONCLUSIONS: This case suggests that when patients with AC found mucosal and muscular adhesions during POEM surgery, the possibility should be considered that the lesion may be caused by a malignant lesion.

Prediction, prevention and management of gastroesophageal reflux after per-oral endoscopic myotomy: An update.

Achalasia cardia, the most prevalent primary esophageal motility disorder, is predominantly characterized by symptoms of dysphagia and regurgitation. The principal therapeutic approaches for achalasia encompass pneumatic dilatation (PD), Heller's myotomy, and the more recent per-oral endoscopic myotomy (POEM). POEM has been substantiated as a safe and efficacious modality for the management of achalasia. Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy, the incidence of gastroesophageal reflux disease (GERD) following POEM is notably higher than with the aforementioned techniques. While symptomatic reflux post-POEM is relatively infrequent, the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications. Contemporary advancements in the field have enhanced our comprehension of the risk factors, diagnostic methodologies, preventative strategies, and therapeutic management of GERD subsequent to POEM. This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux, potential modifications in the POEM technique to mitigate GERD risk, and the strategies for managing reflux following POEM.

Oesophagectomy in End-Stage Achalasia.

Presentation A 53 year old male with known Chicago Classification type II achalasia, and successful pneumatic dilatation five years previously, presented with severe dysphagia and 17.5 kg weight loss over 3 months. Diagnosis He underwent OGD and contrast imaging to reveal a mega oesophagus secondary to progressive achalasia. Treatment After initial nutritional pre-habilitation with naso-enteric feeding, he underwent a laparoscopic heller's myotomy with clinical and radiological improvement. However quick relapse of symptoms and a failed, atonic, massively dilated oesophagus lead to the decision to proceed to transhiatal oesophagectomy. Discussion Achalasia is a spectrum of motility disorder, and where it has progressed to mega-oesophagus, the success of standard therapeutic approaches is limited. End stage achalasia in this context, with nutritional failure or recurrent pneumonia/bronchiectasis, can be safely treated with an oesophageal resection which is curative, removing a "failed" oesophagus in its entirety.

Butterfly Wings Effect on High Resolution Manometry in A Patient with Esophageal Achalasia.

A 57-year-old man presented with dysphagia in solids and liquids deteriorating in the last months and weight loss of 3 kg. A thoracic CT revealed a limit dilatation of the lower esophagus with food residue. An upper endoscopy was performed revealing bubble content and a contraction of the Lower Esophageal Sphincter (LES). A barium esophagogram demonstrated deceleration of esophageal emptying and a bird beak sign indicative of esophageal achalasia (Figure A). High resolution esophageal manometry was performed to evaluate the subtype of achalasia. The catheter could not be intubated into the stomach because of LES spasticity, it folded back cephalad at this level, producing a mirror image, the characteristic "butterfly wings" appearance of a folded manometry catheter (Figure B).

Global trends in incidence and prevalence of achalasia, 1925-2021: A systematic review and meta-analysis.

BACKGROUND: Achalasia poses a significant socioeconomic burden, yet global trends remain undocumented. This study aims to describe the worldwide trends in the incidence and prevalence of achalasia from 1925 to 2021 and explore their correlation with various factors through a comprehensive systematic review. METHODS: We searched the PubMed/MEDLINE, Embase, and Cochrane databases from inception to 30 June 2023, to identify studies reporting the incidence or prevalence of achalasia in the general population. This study utilized pooled estimates with 95% confidence intervals (CI) to estimate the incidence and prevalence of achalasia, and conducted various subgroup analyses. RESULTS: A total of 26 eligible studies covering approximately 269 million participants and 20,873 patients from 14 countries across five continents were included. Global pooled incidence and prevalence of achalasia were estimated to be 0.78 cases per 100,000 person-years (95% CI, 0.64-0.93; number of studies, 26; sample population, 269,315,171) and 10.82 cases per 100,000 person-years (95% CI, 8.15-13.48; number of studies, 14; sample population, 192,176,076), respectively. The incidence of achalasia was higher in Oceania (than Asia and Africa) and in adults (than children) after the introduction of the Chicago classification. Prevalence followed a similar pattern. The pooled incidence of achalasia showed an overall upward trend from 1925 to 2021 (1925-1999; 0.40 [0.32-0.49] vs. 2018-2021; 1.64 [1.33-1.95] cases per 100,000 person-years). CONCLUSIONS: The incidence and prevalence of achalasia have notably increased, particularly with advancements in diagnosis, and show significant variation worldwide, despite the large heterogeneity within the sample population. Further studies are necessary to accurately assess the global incidence and prevalence of achalasia.

Peroral endoscopic myotomy: a two-center retrospective study of practice and adverse events.

Background and study aims: Peroral endoscopic myotomy (POEM) is the preferred technique for the treatment of esophageal motility disorders and is less invasive than surgery. This study was performed to compare two university centers in the practice of POEM, in terms of efficacy and adverse events, for the treatment of esophageal motility disorder. Patients and methods: Retrospective comparative study of patients undergoing a POEM between September 2020 and December 2022 from the University Hospital of Liège (Belgium) and Besançon (France). The clinical success was defined by an Eckardt score ≤ 3 after the procedure. Results: Fifty-five patients were included. In both centers, 87,3% of the patients had achalasia (mostly type II), and 12,7% had another esophageal motility disorder. The use of antibiotic prophylaxis was systematic in Liège center but not in Besançon center (100% and 9.1% respectively). The mean value of the post-operative Eckardt score was 1.55± 2.48 in both center with 93.2% of patients with a score ≤ 3 (92% in Besançon and 94.74% in Liège). The rate of adverse event was generally low. There were two minor adverse events more frequent in Liège, clinical capnomediastinum and pain at day one, but they were managed with conservative treatment. Only 7.3% of the total patients had an infectious phenomenon that did not correlate with the use of antibiotic prophylaxis. Conclusion: The post-operative Eckardt score and the adverse event rate were comparable between the university centers. This study confirmed that POEM is a safe and effective technique. It also showed that using an antibiotic prophylaxis does not influence the development of infectious adverse events.

Robotic Heller Myotomy for Advancements in Surgical Management of Achalasia.

Achalasia is an esophageal motility disorder. It occurs due to the destruction of nerves in the lower esophageal sphincter (LES), which leads to the failure of the LES to relax. Patients typically complain of dysphagia, chest pain, and regurgitation. They often report drinking liquids with solids intake to help propel food boluses into the stomach. The diagnosis of achalasia is typically confirmed with an esophagogram and a motility study (esophageal manometry). An esophagogram classically shows the bird beak sign with tapering in the distal esophagus. The treatment for achalasia includes both surgical and non-surgical options. Surgical treatment is associated with a lower rate of recurrences, high clinical success rate, and durability of symptom relief. The current gold standard of surgical technique is myotomy, or the dividing of the muscle fibers of the distal esophagus. Surgical myotomy can be accomplished via a laparoscopic or robotic technique; per-oral endoscopic myotomy is a new alternative intervention. Due to the theoretical risk of gastroesophageal reflux following a myotomy, an antireflux procedure is sometimes performed. We reviewed the approach to a robotic heller myotomy for the treatment of achalasia.

Long-term efficacy of peroral endoscopic myotomy for achalasia under different criteria.

BACKGROUND: Peroral endoscopic myotomy (POEM) has emerged as a widely accepted treatment for achalasia, with limited studies for over 2 years. Additionally, traditional measurements of achalasia after POEM have deficiencies. The study aimed to analyze the long-term outcomes of POEM under different criteria. METHODS: Patients with achalasia who received POEM between November 2012 and March 2021 were recruited. Patients and characteristics were shown, and risk factors related to two novel definitions of recurrence, symptomatic reflux, and reflux esophagitis were analyzed. RESULTS: Three hundred and twenty-one patients were included. At a median follow-up of 52 months, twenty-three failures happened (7.17%) under the modified criterion, and forty-seven failures occurred (14.64%) under the normal standard. Hospitalization (P = 0.027) and esophageal myotomy length (P = 0.039) were significantly associated with long-term efficacy under the modified and normal criteria, respectively. Fifty-two patients (16.20%) reported reflux symptoms and endoscopy performed in 88 patients revealed reflux esophagitis in 22 cases (25.00%). There were no predictors in the analysis of symptomatic reflux and gender (P = 0.010), LESP (P = 0.013), IRP (P = 0.015), and the esophageal myotomy length (P = 0.032) were statistically related to reflux esophagitis. CONCLUSION: POEM is an extremely safe and effective treatment for achalasia with long-term follow-up. Shorter hospitalization and shorter esophageal myotomy length may decrease the incidence of recurrence under the modified and normal criteria, respectively. Long-term outcomes of POEM are unpredictable. No risk factors were related to symptomatic reflux, and male patients with low preoperative LESP and IRP needed relatively shorter esophageal myotomy to prevent reflux esophagitis.

Fertility and sexual activity in patients with Triple A syndrome.

Objective: Triple A syndrome, caused by autosomal recessively inherited mutations in the AAAS gene is characterized by alacrima, achalasia, adrenal insufficiency, and neurological impairment. To the best of our knowledge, no patients of both sexes have been reported to have offspring. Our aim was to assess the causes of infertility in male patients with this multisystemic syndrome, and to present a female patient that spontaneously conceived a child. Design: Cross-sectional study. Methods: Six males aged 19-48 years were included. Gonadotropins, testosterone, DHEAS, androstenedione, inhibin B, anti-Mullerian hormone measurements and testicular ultrasound were performed. Results: All six male patients had impaired general health and neurological symptoms including erectile and ejaculatory dysfunction. None of them had an offspring. The only demonstrated cause of infertility in our male patients was erectile and ejaculatory dysfunction which precludes sexual intercourse. Our patients had normal libido but were sexually abstinent. Except for low adrenal androgen levels, the concentrations of all measured hormones as well as testicular ultrasound were normal which may indicate the possibility of spermatogenesis in male patients with triple A syndrome. Little is known about fertility in female patients, but based on our observations spontaneous pregnancies seem to be possible. Conclusion: Our results contribute to still scarce knowledge on fertility in patients with Triple A syndrome and as well represents a foundation for further research on causes of infertility and possible treatment options.
