RESUMO
BACKGROUND: There is limited evidence on the efficacy of peroral endoscopic myotomy (POEM) in patients with esophageal diverticula. AIMS: This meta-analysis aimed to assess the efficacy and safety profile of POEM in patients with Zenker (ZD) and epiphrenic diverticula. METHODS: With a literature search through August 2020, we identified 12 studies (300 patients) assessing POEM in patients with esophageal diverticula. The primary outcome was treatment success. Results were expressed as pooled rates and 95% confidence intervals. RESULTS: Pooled rate of technical success was 95.9% (93.4%-98.3%) in ZD patients and 95.1% (88.8%-100%) in patients with epiphrenic diverticula. Pooled rate of treatment success was similar for ZD (90.6%, 87.1%-94.1%) and epiphrenic diverticula (94.2%, 87.3%-100%). Rates of treatment success were maintained at 1 year (90%, 86.4%-97.4%) and 2 years (89.6%, 82.2%-96.9%) in ZD patients. Pooled rate of symptom recurrence was 2.6% (0.9%-4.4%) in ZD patients and 0% in patients with epiphrenic diverticula. Pooled rates of adverse events and severe adverse events were 10.6% (4.6%-16.6%) and 3.5% (0%-7.4%) in ZD and 8.4% (0%-16.8%) and 8.4% (0%-16.8%) in epiphrenic diverticula, respectively. CONCLUSION: POEM represents an effective and safe therapy for the treatment of esophageal diverticula.

INTRODUCTION: Gastric peroral endoscopic pyloromyotomy (G-POEM) is a novel option for patients with gastroparesis. It involves submucosal tunneling across the pylorus, followed by pyloromyotomy, and subsequent closure of the endoscopic tunnel. The aim of this study was to determine the learning curve for G-POEM. METHODS: Consecutive patients undergoing G-POEM by a single operator were included from a prospective registry over 2 years. Demographics, procedure info, postprocedure follow-up data, and adverse events were collected. Nonlinear regression and cumulative sum control chart analyses were conducted for the learning curve. Clinical outcomes were improvement in Gastroparesis Cardinal Symptom Index score and gastric emptying scintigraphy. RESULTS: Thirty-six patients were included (16.7% M, mean age 46 y). The majority had idiopathic gastroparesis (n=16, 44%), with the remaining having diabetes (n=5, 17%), postsurgical (n=10, 28%), or other (n=4, 11%). Technical success was achieved in 35 of 36 (97%). There was a significant reduction in the total Gastroparesis Cardinal Symptom Index score (2.09 units, P<0.00001) and a significant reduction in postoperative gastric emptying scintigraphy (82.44 mins, P<0.00001). Mean follow-up was 15 months (SD, 1.05). Median procedure time was 60.5 minutes (range, 35 to 136). Cumulative sum control chart shows 60-minute procedure was achieved at the 18th procedure. Procedure durations further reduced with consequent procedures with the last 3 being 45 minutes, thus demonstrating continued improvement with ongoing experience (nonlinear regression P<0.0001). CONCLUSION: Endoscopists experienced in G-POEM are expected to achieve a reduction in procedure time over successive cases, with efficiency reached at 60.5 minutes and a learning rate of 18 cases with continuing improvement.

Esophagocardiomyotomy followed by anterior fundoplication is a standard treatment of achalasia cardia, whereas cruroraphy with complete or partial posterior fundoplication is carried out for hiatal hernia and gastroesophageal reflux disease. The most common postoperative complications of hiatal hernia repair are dysphagia due to malformed cuff, phenomenon of 'telescope' and slow gastric emptying syndrome. Recurrent hiatal hernia is observed in 3-15% of cases. Currently, there are a lot of reports devoted to redo antireflux procedures in patients with hiatal hernia. The goal of the study is to demonstrate difficulties of diagnosis and treatment in a patient with achalasia cardia after previous hiatal hernia repair.

Up to 77% of Down syndrome (DS) patients have associated structural or functional gastrointestinal abnormalities. Functional disturbances, such as processes affecting the enteric nervous system, can often affect the outcome of corrective surgical procedures. Recently, an association between DS and achalasia has been reported. In this report we present a 28-year-old male patient with a history of Down syndrome and achalasia, who presented with recurrent dysphagia, gastroesophageal reflux, and recurrent aspirations. The patient had previously undergone a laparoscopic Heller myotomy with Dor fundoplication. Unfortunately, despite this surgery, he continued to require multiple esophageal dilations, and intraesophageal administration of Botox therapy. Additionally, there were numerous subsequent hospital admissions for recurrent aspiration pneumonia. Evaluation revealed an incomplete myotomy and a revision long Heller myotomy was successfully performed intraabdominally and he is now symptom and aspiration free.

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.

This study aims to develop a standardized algorithm for gastroesophageal image acquisition and diagnostic assessment using real-time MRI. Patients with GERD symptoms undergoing real-time MRI of the esophagus and esophagogastric junction between 2015 and 2018 were included. A 10 ml bolus of pineapple juice served as an oral contrast agent. Patients performed Valsalva maneuver to provoke reflux and hiatal hernia. Systematic MRI assessment included visual presence of achalasia, fundoplication failure in patients with previous surgical fundoplication, gastroesophageal reflux, and hiatal hernia. A total of 184 patients (n = 92 female [50%], mean age 52.7 ± 15.8 years) completed MRI studies without adverse events at a mean examination time of 15 min. Gastroesophageal reflux was evident in n = 117 (63.6%), hiatal hernia in n = 95 (52.5%), and achalasia in 4 patients (2.2%). Hiatal hernia was observed more frequently in patients with reflux at rest (n = 67 vs. n = 6, p < 0.01) and during Valsalva maneuver (n = 87 vs. n = 8, p < 0.01). Real-time MRI visualized a morphologic correlate for recurring GERD symptoms in 20/22 patients (90%) after fundoplication procedure. In a large-scale single-center cohort of patients with GERD symptoms undergoing real-time MRI, visual correlates for clinical symptoms were evident in most cases. The proposed assessment algorithm could aid in wider-spread utilization of real-time MRI and provides a comprehensive approach to this novel imaging modality.

BACKGROUND: Several studies have examined the efficacy of gastric peroral endoscopic myotomy (G-POEM) for gastroparesis. AIM: To evaluate the mid-term efficacy of G-POEM by meta-analysis of studies with a minimum 1 year of follow-up. METHODS: We reviewed several databases from inception to 10 June 2021 to identify studies that evaluated the efficacy of G-POEM in refractory gastroparesis, and had at least 1 year of follow-up. Our outcomes of interest were clinical success at 1 year, adverse events, difference in mean pre- and 1 year post-procedure Gastroparesis Cardinal Symptom Index (GCSI) score, and difference in mean pre- and post-procedure EndoFLIP measurements. We analysed data using a random-effects model and assessed heterogeneity by I2 statistic. RESULTS: We included 10 studies comprising 482 patients. Pooled rates (95% CI) of clinical success at 1 year and adverse events were 61% (49%, 71%) and 8% (6%, 11%), respectively. Mean GCSI at 1 year post-procedure was significantly lower than pre-procedure; mean difference (MD) (95% CI) -1.4 (-1.9, -0.9). Mean post-procedure distensibility index was significantly higher than pre-procedure in the clinical success group at 40 and 50 mL volume distension; standardised mean difference (95% CI) 0.82 (0.07, 1.64) and 0.91 (0.32, 1.49), respectively. In the clinical failure group, there was no significant difference between mean pre- and post-procedure EndoFLIP measurements. CONCLUSIONS: G-POEM is associated with modest clinical success at 1 year. Additional studies with longer follow-up are required to evaluate its longer-term efficacy.

BACKGROUND: Achalasia is a rare benign esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES). The treatment of achalasia is not curative, but rather is aimed at reducing LES pressure. In patients who have failed noninvasive therapy, surgery should be considered. Myotomy with partial fundoplication has been considered the first-line treatment for non-advanced achalasia. Recently, peroral endoscopic myotomy (POEM), a technique that employs the principles of submucosal endoscopy to perform the equivalent of a surgical myotomy, has emerged as a promising minimally invasive technique for the management of this condition. AIM: To compare POEM and laparoscopic myotomy and partial fundoplication (LM-PF) regarding their efficacy and outcomes for the treatment of achalasia. METHODS: Forty treatment-naive adult patients who had been diagnosed with achalasia based on clinical and manometric criteria (dysphagia score ≥ II and Eckardt score > 3) were randomized to undergo either LM-PF or POEM. The outcome measures were anesthesia time, procedure time, symptom improvement, reflux esophagitis (as determined with the Gastroesophageal Reflux Disease Questionnaire), barium column height at 1 and 5 min (on a barium esophagogram), pressure at the LES, the occurrence of adverse events (AEs), length of stay (LOS), and quality of life (QoL). RESULTS: There were no statistically significant differences between the LM-PF and POEM groups regarding symptom improvement at 1, 6, and 12 mo of follow-up (P = 0.192, P = 0.242, and P = 0.242, respectively). However, the rates of reflux esophagitis at 1, 6, and 12 mo of follow-up were significantly higher in the POEM group (P = 0.014, P < 0.001, and P = 0.002, respectively). There were also no statistical differences regarding the manometry values, the occurrence of AEs, or LOS. Anesthesia time and procedure time were significantly shorter in the POEM group than in the LM-PF group (185.00 ± 56.89 and 95.70 ± 30.47 min vs 296.75 ± 56.13 and 218.75 ± 50.88 min, respectively; P = 0.001 for both). In the POEM group, there were improvements in all domains of the QoL questionnaire, whereas there were improvements in only three domains in the LM-PF group. CONCLUSION: POEM and LM-PF appear to be equally effective in controlling the symptoms of achalasia, shortening LOS, and minimizing AEs. Nevertheless, POEM has the advantage of improving all domains of QoL, and shortening anesthesia and procedure times but with a significantly higher rate of gastroesophageal reflux.

PURPOSE: Esophageal dysmotility and disorders of the lower esophageal sphincter are well documented in morbidly obese patients. Esophageal achalasia has been reported in up to 1% of obese patients but the development of such esophageal motility disorder after laparoscopic sleeve gastrectomy (LSG) is extremely rare. The purpose of this video was to demonstrate the management of a type II esophageal achalasia diagnosed in a 46-year-old female patient 4-year after LSG. MATERIALS AND METHODS: An intraoperative video has been anonymized and edited to demonstrate the feasibility of laparoscopic Heller myotomy and anterior Dor fundoplication on the mentioned patient. RESULTS: The operation started with the section of the perigastric adhesions. Proceeding in a clockwise direction, the esophagogastric junction, the anterior esophageal wall, and the His angle were freed. A residual slightly dilated fundus was found and isolated. After mobilization of the distal esophagus and identification of the anterior vagus nerve, a "hockey stick" myotomy was carried out for 6 cm on the esophagus and for 2 cm on the gastric side. An anterior Dor fundoplication was fashioned using the residual gastric fundus. CONCLUSION: Esophageal achalasia in patients that previously underwent LSG is exceptional but should always be suspected in case of pathognomonic symptoms onset. In tertiary referral centers, laparoscopic Heller myotomy and, if technically feasible, an anterior Dor fundoplication seem safe and effective to relieve gastroesophageal outflow obstruction and prevent gastroesophageal reflux.

The Reyes technique for the management of severe, acute corrosive injuries of the esophagus has been modified and successfully applied to two children and one adult whose cases are reported. None developed stricture and two were uncomplicated. Esophagomegaly, motility dysfunction, upper gastrointestinal bleeding, and pneumonitis complicated the hospitalization of one child whose subsequent course has been asymptomatic. Until more experience can be recorded, widespread use is not yet recommended.

The Serra-Dória procedure has been used in the treatment of advanced or relapsed megaesophagus due to Chagas disease. Little is known, however, about cardiovascular complications following this procedure. The purpose of this study was to settle independent predictors of cardiovascular complications following the Serra-Dória procedure in patients with megaesophagus secondary to chronic Chagas disease. A total of 76 patients who underwent the Serra-Dória operation for Chagas disease megaesophagus from 1998 to 2010 were included. A multivariate stepwise logistic regression analysis was performed to identify predictors of cardiovascular complications. Mean age was 61±10 years; 55% were male. Advanced megaesophagus (grades III/IV) were found in 65 (86%) of patients. Twenty-two (29%) patients had one comorbidity, and five (7%) three co-morbidities before operation. Two (3%) patients died following the operation. Twenty-nine (38%) patients presented cardiovascular complication following the Serra-Dória procedure; 15 (44%) were mild, 7 (21%) moderate, and 12 (35%) severe. Age>61 years was the only independent predictor of cardiovascular complication following Serra-Dória procedure. In patients with megaesophagus secondary to chronic Chagas disease, the Serra-Dória procedure is associated with a low mortality rate and a high frequency of cardiac complication.

PURPOSE: To report an unusual case of dysphagia that developed immediately after stent-grafting of a thoracoabdominal aortic aneurysm. CASE REPORT: A 79-year-old woman was submitted to a staged hybrid repair of a thoracoabdominal aortic aneurysm and developed new onset dysphagia and regurgitation early after stent-grafting of the thoracic aorta. Esophageal imaging showed a marked endoluminal stenosis, suggesting the development of secondary achalasia. The patient was submitted to endoscopic injections of botulinum toxin at the lower esophageal sphincter, which completely resolved the symptoms. CONCLUSION: Acute dysphagic syndrome after thoracic aorta endografting has been anecdotically reported, and its etiology remains undefined. In this report, we illustrate the clinical features of this rare condition, discuss etiological hypotheses, and suggest a noninvasive therapeutic approach.

The triad of adrenocortical insufficiency with alacrima and achalasia is an unusual disease entity in paediatrics. The association of autonomic and peripheral neuropathies has more commonly been reported in older individuals. We describe four children (two siblings) with this disorder, aged between 3 and 6 years at diagnosis, all of whom had clinical neurological abnormalities when examined between 6 and 8 years of age. In addition, we performed cardiovascular autonomic testing in three subjects: heart rate variation during deep breathing was abnormal in all three; Valsalva ratio was abnormal in two; and postural systolic blood pressure response was abnormal in one. Pupillary reflexes were abnormal in the only subject in which they could be measured. These results indicate that subtle neurological and, in particular, autonomic abnormalities can be detected at an early age. We propose that autonomic neuropathy be considered as an integral feature of this rare condition and suggest the term "4A" syndrome as a useful mnemonic for the association of adrenocortical insufficiency, achalasia and alacrima with autonomic and other neurological abnormalities.
