Abstract
BACKGROUND Esophageal symptoms of gastroesophageal reflux are the same in functional heartburn, non-erosive disease, and erosive disease. Their patient-perceived intensity may be related to gastroesophageal reflux intensity. OBJECTIVE To evaluate whether the symptoms in GERD patients are related to the intensity of gastroesophageal acid reflux. METHODS To test this hypothesis, 68 patients with heartburn (18 with functional heartburn, 28 with non-erosive reflux disease, and 22 with erosive reflux disease) had their symptoms evaluated by the Velanovich score (which mainly focuses on heartburn) and the Eating Assessment Tool (EAT-10) (which focuses on dysphagia). They were submitted to esophageal endoscopy and then, on another day, they answered the Velanovich and EAT-10 questionnaires and underwent manometry and 24-hour pHmetry (measured 5 cm proximal to the upper border of the lower esophageal sphincter). RESULTS The Velanovich score was higher in patients with non-erosive and erosive diseases than in those with functional heartburn. The mean EAT-10 score did not differ between functional heartburn, erosive, and non-erosive gastroesophageal reflux disease. Considering the threshold of ≥5 to define dysphagia, 4 (22%) patients with functional heartburn, 12 (43%) with non-erosive disease, and 9 (41%) with erosive disease had dysphagia (P=0.18). There was: a) a moderate correlation between the Velanovich and DeMeester score and between Velanovich score and the percentage of acid exposure time (AET); b) a weak correlation between EAT-10 and DeMeester score and between EAT-10 and acid exposure time. CONCLUSION There is a moderate positive correlation between heartburn and gastroesophageal reflux measurement. Dysphagia has a weak positive correlation with reflux measurement.

Abstract
PURPOSE The purpose of our study was to evaluate the role of timed barium esophagogram (TBE) in quantitative measurement of improved esophageal emptying in primary achalasia patients treated with POEM. Also, we investigated the correlation of TBE with improvement of clinical symptoms as measured by Eckardt score. METHODS This retrospective study included 30 patients who underwent POEM due to primary achalasia. As a baseline study, all patients underwent TBE and were evaluated for clinical status by Eckardt score based on presence and frequency of dysphagia, regurgitation, substernal pain, and weight loss. Follow-up evaluation was performed within 3 months after POEM. Pre- and post-POEM TBE results were compared using a calculated value based on summation of height of the barium columns on 1-, 2- and 5-min delayed images. Also, the correlation of TBE with improvement of Eckardt score was evaluated using Pearson's correlation test. RESULTS There was a significant decrease in the calculated value of height between pre- and post-POEM TBE studies (40.5 ± 15.8-17.0 ± 11.6, p < 0.01). Also, the Eckardt score decreased significantly after POEM (6.7 ± 2.0-0.8 ± 1.0, p < 0.01). Pearson's correlation test revealed a positive correlation between improvement of TBE results and Eckardt score (correlation coefficient = 0.56, p < 0.01). CONCLUSION TBE is an objective method for quantitative measurement of improved esophageal emptying in primary achalasia patients treated with POEM and shows positive correlation with clinical symptoms evaluated by Eckardt score.

Abstract
INTRODUCTION Gastric peroral endoscopic myotomy (G-POEM) is a promising but still experimental endoscopic method for the treatment of gastroparesis. CASE REPORT We describe the case of a 31 years old female patient with severe refractory postsurgical gastroparesis preceded by fundoplication done for reflux disease. She has had digestive problems since childhood. In 2018, the first G-POEM was performed but did not lead to any clinical improvement. We proposed to perform a repeated G-POEM given that impedance planimetry measurement showed persistent pylorospasm. The patient agreed and the second G-POEM was performed in February 2021 (the first re-G-POEM in the Czech Republic) with a satisfactory clinical result; a subsequent gastric emptying study also showed a significant improvement. CONCLUSION This case report shows the feasibility of performing a repeated endoscopic pyloromyotomy in patients with gastroparesis and proven pylorospasm. One can only hypothesize whether the lack of effect of the first procedure was caused by an incomplete myotomy (failure of the procedure) or the need for a double myotomy, which is considered a standard in some centers.

Abstract
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.

Abstract
Objective Esophageal diverticulum is rare, and the concomitance of esophageal motility disorders (EMDs) and the efficacy of novel endoscopic treatment have not been investigated in Japan. Methods An examination including high-resolution manometry (HRM) was performed for patients with both EMDs and epiphrenic diverticulum. EMD-related epiphrenic diverticulum and Zenker's diverticulum were treated using salvage peroral endoscopic myotomy (s-POEM) and endoscopic diverticulotomy, respectively. Results Six cases of epiphrenic diverticulum were diagnosed in this study. Among 125 patients with achalasia and spastic disorders, concomitant epiphrenic diverticulum was observed in 4 (3.2%). Of these, three showed a normal lower esophageal sphincter pressure on HRM, although gastroscopy and esophagography revealed typical findings of an impaired lower esophageal sphincter relaxation. These four patients were successfully treated with s-POEM, and the Eckardt score improved from 6.3 to 0.25 at 32.5 (range: 13-56) months of follow-up, with equivalent treatment efficacy to that observed for achalasia and spastic disorders without epiphrenic diverticulum. In contrast, the two remaining cases of epiphrenic diverticulum had normal esophageal motility. Six cases of Zenker's diverticulum were diagnosed, and endoscopic diverticulotomy was successfully performed in all. The dysphagia score decreased from 2.8 to 0.17 at 14.8 (range: 2-36) months of follow-up. Overall, 12 endoscopic treatments were performed for esophageal diverticulum; no adverse events were observed. Conclusion In epiphrenic diverticulum patients, concomitant EMDs are not rare and should be carefully diagnosed. A normal lower esophageal sphincter pressure on HRM does not always mean a normal lower esophageal sphincter relaxation. S-POEM and endoscopic diverticulotomy are effective minimally invasive treatment options for EMD-related epiphrenic diverticulum and Zenker's diverticulum.

Abstract
Aspiration, the inadvertent introduction of fluids or solids into the trachea, is a severe risk in patients with achalasia, presenting major challenges for anesthesia providers. Achalasia is an autoimmune reaction resulting in decreased lower esophageal peristalsis and the inability of the lower esophageal sphincter to relax, preventing the passage of food and liquids. A 47-yearold woman with a history of achalasia presented to the endoscopy suite for esophagogastroduodenoscopy. The patient was admitted with complaints of dysphagia and the inability to tolerate solids and liquids. Despite the recommendation from the gastroenterology team for monitored anesthesia care, the anesthesia care team advocated for general anesthesia with rapid sequence induction to protect the airway. On introduction of the video laryngoscope (GlideScope, Verathon Inc), a pool of saliva and food particles were observed in the posterior oropharynx. This case study examines a severe case of achalasia requiring unconventional treatment. This case illustrates the need for maintaining a high index of suspicion for aspiration risk in patients with achalasia during their precarious and stressful course of management, and the importance of collaboration between the anesthesia and the gastroenterology care teams in safely managing these patients.

Abstract
The pathophysiology of Gastroesophageal reflux disease (GERD) is multifactorial determined and remains a matter of discussions between the involved medical subspecialties, mainly gastroenterologists and gastrointestinal surgeons, but also ear-nose-and-throat colleagues and pulmonologists. The purpose of this manuscript is an overview on the different pathophysiologic components of GERD, their influence as well as a certain weighing of their involvement in the disease.
The lower esophageal sphincter (LES) represents together with the muscles and ligamentous structures of the diaphragm at the esophageal hiatus the antireflux barrier between esophagus and stomach. The crucial factor in GERD is an increased amount of gastric contents refluxing into the esophagus above the physiologic level.
This creates pathologic esophageal acid exposure (EAE) to the mucosa, which may lead to symptoms and damage. The underlying pathophysiologic mechanisms are anatomical components such as LES and diaphragm, and functional components such as LES-incompetence, transient LES relaxations, impaired esophageal motility, gastroduodenal dysfunctions and alterations of the refluxate such as duodeno-gastro-esophageal reflux.
The quantitative assessment of these components has been reported in a number of studies demonstrating the importance of LES-incompetence (incidence 80 %) and the role of hiatal hernia (incidence 80 %) in the severity of GERD indicated by excessive esophageal acid exposure and visible damage of the esophageal mucosa. All known pathophysiologic components of GERD can be investigated currently by diagnostic assessment, detecting a LES-incompetence or an increase in transient relaxations, detecting a hiatal hernia with increasing size, detecting increasing exposure to gastric contents in addition to other possible functional associated disorders such as an insufficient esophageal motility and or a delayed gastric emptying, which all can aggravate the disease and the patient's status.

Abstract
PURPOSE OF REVIEW This review highlights recent research advances regarding the pathophysiology and treatment of gastroparesis. RECENT FINDINGS Differences in brain activity have been identified on functional MRI imaging in gastroparesis patients with nausea. Abdominal pain is common in patients with gastroparesis and does not correlate with the severity of gastric emptying delay, though may be associated with depression and anxiety. Autonomic dysfunction may play an important role in the pathophysiology of gastroparesis. There is increasing sentiment that gastroparesis should be considered a part of the same spectrum of gastric neuromuscular disorders. The risk of tardive dyskinesia with metoclopramide has likely been significantly overestimated historically. Endoscopic BoTox injection of the pylorus and gastric electrical stimulation remain controversial treatments for gastroparesis. New, highly selective 5-hydroxytryptamine 4 (5-HT4) agonists appear safe and may be effective in improving symptoms of gastric emptying. Long-term data assessing the use of gastric peroral endoscopic myotomy (G-POEM) for the treatment of refractory gastroparesis suggest durable clinical improvement. SUMMARY Altered central processing and autonomic dysfunction may be important factors in the pathogenesis of gastroparesis. While the risk of tardive dyskinesia appears much lower than historically advertised, there is increasing hope for novel therapeutics with the advent of new 5-HT4 agonists, neurokinin-1 receptor (N1KR) antagonists, and G-POEM.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) has been recommended for achalasia treatment. To prevent the potential of infective risk, antibiotic prophylaxis is usually administered, whereas the additional need of antibiotic therapy after POEM is uncertain. The primary endpoint was to determine whether prophylaxis versus prophylaxis plus short therapy was needed after POEM. METHODS Consecutive patients scheduled for POEM were randomly assigned (1:1) to group A (prophylactic cefazolin 2 g IV) or group B (prophylaxis + cefazolin 2 g IV × 3 followed by oral amoxicillin/clavulanate 3 g/day). Infective risk was assessed by means of host response, namely body temperature and serum levels of white blood cells and C-reactive protein; immune response (the cytokines interleukin [IL]-6, IL-1β, and tumor necrosis factor-α and microbial translocation mediators lipopolysaccharide binding protein and soluble CD14); and blood cultures at time points before (t0) and after (t1, t2) POEM. RESULTS After POEM, none of the 124 enrolled patients (54.6 ± 12.6 years old; 64 men) developed any fever (body temperature: t0, 36.56± .49°C; t1, 36.53± .52°C; t2, 36.48± .41°C), without any differences between groups at any time point. Regarding systemic inflammation, no difference was reported between groups in serum levels of C-reactive protein and white blood cells. Considering microbial translocation mediated response, lipopolysaccharide binding protein (group A: t0, 1539 ± 168.6 pg/mL; t1, 1321 ± 149.1 pg/mL; t2, 2492 ± 283.2 pg/mL; group B: t0, 1318 ± 115.9 pg/mL; t1, 1492 ± 163.8 pg/mL; t2, 2600 ± 328.2 pg/mL) and soluble CD14 (group A: t0, 2.16 ± .15 μg/mL; t1, 1.89 ± .15 μg/mL; t2, 2.2 ± .15 μg/mL; group B: t0, 2.1 ± .13 μg/mL; t1, 2 ± .13 μg/mL; t2, 2.5 ± .2 μg/mL) were similar between the 2 groups; the immune response cytokines IL-6, IL-1β, and tumor necrosis factor-α also were similar in the 2 groups. In relation to blood cultures, at t1 the group B bacteremia rate was 3.2% (2/62) and group A was 1.6% (1/62) with no difference (P = .6). All subsequent blood cultures were negative at t2. CONCLUSIONS According to our study, postprophylactic short-term antimicrobial therapy after POEM is not required because of a very low residual infective risk. (Clinical trial registration number: NCT03587337.).

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) has a high prevalence worldwide, and its incidence is increasing annually. Modified Xiaochaihu Decoction (MXD) could relieve the symptoms of GERD, but the effects of MXD on GERD manifestations and relapse prevention need to be further explained. Therefore, we performed a prospective, double-blind, and double-simulation study.
AIM To verify the efficacy of MXD for GERD and its effect on esophageal motility.
METHODS Using randomization, double-blinding, and a simulation design, 288 participants with GERD were randomized to the treatment group and control group and received herbs (MXD) plus omeprazole simulation and omeprazole plus herbs simulation, respectively, for 4 wk. The GERD-Q scale score and esophageal manometry were measured at baseline, after treatment, and at 1 mo and 3 mo follow-up visits when medication was complete to evaluate recurrence indicators.
RESULTS The GERD-Q scale score in both groups decreased significantly compared to those before treatment (P < 0.01). However, no significant difference was observed between the two groups (P > 0.05). Esophageal manometry showed that participants with lower esophageal sphincter pressure reduction and the proportion of ineffective swallowing (more than 50%) improved in both groups from baseline (P < 0.01), especially in the treatment group (P < 0.05). The percentage of small intermittent contractions, large intermittent contractions, and increased pre-phase contractions in the treatment group significantly improved compared with baseline (P < 0.05) but did not improve in the control group (P > 0.05). There was no significant difference between the groups after treatment (P > 0.05). The percentage of weak esophageal contractility (distal contractile integral < 450 mmHg·s·cm), improved in both groups (P < 0.01), but no significant difference was observed between the groups after treatment (P > 0.05). The relapse rate in the treatment group was lower than that in the control group at the 1 mo (P < 0.01) and 3 mo follow-up (P < 0.05).
CONCLUSION MXD has a similar therapeutic effect to omeprazole in mild-to-moderate GERD. The therapeutic effect may be related to increased pressure in the lower esophageal sphincter and reduced ineffective swallowing.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is used to treat achalasia with efficacy and reliability. However, during the procedure potential complications require attention in terms of anesthesia. This study aimed to investigate complications of the POEM procedure and its effects on arterial blood gas (ABG) parameters, peak airway pressures (PIP), hemodynamics, and postoperative analgesia requirements. METHODS Data from 220 patients who underwent POEM between 2014 and 2017 were retrospectively assessed. During the procedure, ABG samples, PIP, mean arterial pressure, and heart rate were recorded. The effects of the procedure and paracentesis on ABG, PIP, mean arterial pressure, heart rate, perioperative complications, and postoperative analgesia requirements were assessed. RESULTS Data from 220 POEM patients were analyzed. During the procedure, the mean PaCO2 was 48.27±6.34 mm Hg, which was significantly higher than the PaCO2 values before and after the procedure. The mean increase in maximum PIP was 5.90±3.49 cmH2O during the procedure. However, there was a significant decrease in PaCO2 and PIP values in cases with paracentesis compared with those without paracentesis. With regards to complications, subcutaneous emphysema (48, 21.8%), pneumoperitoneum requiring decompression (66, 30%), pneumothorax (1, 0.5%), aspiration pneumonia (1, 0.5%), and bronchospasm (5, 2.2%) were observed during the procedure. In the postoperative period, 58 patients (26%) had additional analgesia requirements because of visual analog scale values >3. CONCLUSION Periprocedural abdominal decompression with veress needle led to a reduction in arterial PaCO2 and PIP, and improved postoperative analgesia. Serious complications because of perioperative aspiration and CO2 insufflation were observed during the POEM procedure.

Abstract
BACKGROUND AND AIMS Gastroparesis (GP) is a multifactorial disease associated with a large burden on the health care systems. Pyloric-directed therapies including gastric peroral endoscopic myotomy (G-POEM) can be effective in improving patient quality of life and symptom severity. We report on the safety and efficacy of G-POEM and its impact on the quality of life of patients managed at a large referral center. METHODS Consecutive patients with confirmed GP referred for G-POEM due to failure of medical therapy were included. All patients were assessed at baseline and then at 1, 3, 6, and 12 and 24 months after G-POEM using validated symptom and quality of life instruments, including the Gastroparesis Cardinal Symptom Index (GCSI), Patient Assessment of Gastrointestinal Disorders Symptom Severity Index (PAGI-SYM), and 36-Item Short Form Survey (SF-36). Patients were evaluated before and 6 months after the procedure with EGD, 4-hour scintigraphy, and pyloric EndoFLIP. Technical success was defined as the ability to perform full-thickness pyloromyotomy. Clinical response was defined as an improvement of ≥1 point on GCSI. RESULTS Fifty-two patients (median age, 48 years; range, 25-80 years, 88% female) underwent G-POEM between February 2018 and September 2020 for the following phenotypes: vomiting-predominant (n=30), dyspepsia-predominant (n=16), and regurgitation-predominant (n=6) GP. The technical success rate was 100%. Adverse events were noted in 3 of 52 patients (5.77%), and were all managed successfully endoscopically. Clinical response was achieved in 68%, 58%, and 48% of patients at 1-month, 6-month, and 12-month follow-up (P < .001, P < .001, and P < .01, respectively). When classified by the cause of GP, the clinical response rates were diabetic GP 64% (11 of 17), postsurgical GP 67% (6 of 9), and idiopathic GP 72% (13 of 18). A statistically significant improvement in PAGI-SYM scores was observed at 1, 3, 6, 12, and 24 months, in addition to significant improvement in several domains of SF-36. Mean 4-hour gastric emptying was reduced 6 months after G-POEM (10.2%) compared with baseline (36.5%, P < .001). We report a significant reduction in the number of emergency department visits and days spent in the hospital up to 24 months after G-POEM. CONCLUSIONS G-POEM appears to be a safe and feasible treatment alternative for refractory GP with significant short-term and mid-term improvements in overall symptoms, quality of life scores, and health care utilization.

Abstract
BACKGROUND AND AIMS In advanced achalasia patients with sigmoid esophagus, peroral endoscopic myotomy (POEM) might be technically challenging and its outcomes are not well known in western population. Hence, our study aims were to assess and compare the safety and efficacy of POEM in achalasia patients with and without sigmoid esophagus. MATERIALS AND METHODS Medical records of achalasia patients who had POEM at our institution between April 2014 and December 2019 were reviewed. Patients who underwent work-up comprising timed barium esophagram (TBE) and high-resolution esophageal manometry (HREM) before POEM along with 2-month post-POEM esophageal pH study, TBE and HREM were included in the final analysis. Patients were categorized as either sigmoid or no sigmoid esophagus based on the morphology of esophagus on TBE as per Japan Esophageal Society guidelines. Treatment success was defined as reduction of post-POEM Eckardt score to ≤3. RESULTS A total of 168 patients (sigmoid esophagus=20; no sigmoid esophagus=148) were included. Esophageal width on TBE at 1 minute was significantly higher in sigmoid esophagus group compared with no sigmoid esophagus group (4.9 vs. 3.0 cm, P<0.001). Procedural outcomes and complications were similar in both groups. At 2-month follow-up, both groups had significant improvement in Eckardt scores, TBE, and HREM parameters. Treatment success was high and similar in both sigmoid and no sigmoid groups (94.4% vs. 93.2%, P=0.84). The rates of gastroesophageal reflux disease were also similar in both groups. CONCLUSIONS Our study findings suggest that POEM is safe and highly effective treatment for achalasia patients with sigmoid esophagus similar to those without sigmoid esophagus in western population. POEM should be considered as the treatment of choice in advanced achalasia with sigmoid esophagus.

Abstract
Achalasia is a disorder of impaired lower esophageal sphincter (LES) relaxation and failed peristalsis traditionally characterized by manometry.1 As impaired LES relaxation is a mechanism of reduced esophagogastric junction (EGJ) opening, abnormally reduced EGJ distensibility assessed with functional luminal imaging probe (FLIP) was reported among patients with untreated achalasia.2-5 Therefore, we aimed to describe the performance characteristics of EGJ opening parameters on FLIP panometry among a large cohort of treatment-naïve achalasia patients.

Abstract
Chagas disease, caused by the infection of the protozoan parasite Trypanosoma cruzi, has clinical consequences in the heart and digestive tract. The most important changes in the digestive tract occur in the esophagus (megaesophagus) and colon (megacolon). Esophageal dysfunction in Chagas disease results from damage of the esophageal myenteric plexus, with loss of esophageal peristalsis, partial or absent lower esophageal sphincter relaxation, and megaesophagus, which characterizes secondary esophageal achalasia. The treatment options for the disease are similar to those for idiopathic achalasia, consisting of diet and behavior changes, drugs, botulinum toxin, peroral endoscopic myotomy (POEM), pneumatic dilation of the lower esophageal sphincter, laparoscopic Heller myotomy, and esophagectomy. Chagas disease causes a life-threatening cardiopathy, and this should be considered when choosing the most appropriate treatment for the disease. While some options are palliative, for temporary relief of dysphagia (such as drugs, botulinum toxin, and pneumatic dilation), other therapies provide a long-term benefit. In this case, POEM stands out as a modern and successful strategy, with good results in more than 90% of the patients. Esophagectomy is the option in Chagas disease patients with advanced megaesophagus, despite the increased risk of complications. In these cases, peroral endoscopic myotomy may be an option, which needs further evaluation.

Abstract
INTRODUCTION The modification of NOTES (natural orifice transluminal endoscopic surgery) by mucosal safety flap has introduced us to the world of third space endoscopy (TSE). POEM (per-oral endoscopic myotomy) for achalasia cardia being its first vista, the realm expanded so that we can now remove en bloc a subepithelial/intramural tumor by POET (per-oral endoscopic tumor resection), perform G-POEM (gastric per-oral endoscopic myotomy) for refractory gastroparesis, restore esophageal continuity in complete obstruction by performing POETRE (per-oral endoscopic tunneling for the restoration of the esophagus), divide the septum in Zenker diverticulum completely with negligible risk of perforation by Z-POEM (Zenker per-oral endoscopic myotomy) and relieve constipation in Hirschsprung disease by PREM (per-rectal endoscopic myotomy). However, the real potential of TSE became evident with the introduction of POEM with fundoplication. TSE has opened the gates of the peritoneal cavity. Improved expertise and equipment will make the role of endoscopist complimentary to the surgeon with the dawn of a new field in therapeutic endoscopy. AREAS COVERED This review intends to comprehensively discuss the various aspects of POEM for achalasia studied so far followed by a brief discussion about other applications of TSE and the future perspectives in this exciting field.

Abstract
BACKGROUND POEM (Per Oral Endoscopic Myotomy) is rapidly becoming a valid option for surgical myotomy in achalasia patients. Several techniques to perform POEM are described, but all concentrate on the division of the circular muscle fibers in a proximal-to-distal fashion. Our aim is to present the distal-to-proximal, or the bottom-up technique using the Flush/Dual knife, which overcomes the disadvantages of the standard technique. METHODS A retrospective study on a prospectively maintained database was performed on all patients treated by POEM in our institution. Clinical presentation, operating time, adverse events, and outcomes were studied. RESULTS POEM was performed on 105 achalasia patients. The first 15 cases were performed using the standard technique and were compared to the next 90 cases performed using the bottom-up technique. The average preop Eckardt scores in the standard and bottom-up groups were 9.5 and 8.8, respectively, declining to 1.4 and 0.5, 3 months post myotomy (p < 0.001). The average procedure time was 111.2 min for the standard technique and 74.3 for the bottom-up technique. (p = 0.002). Perioperative adverse events included 14 instances of pneumoperitoneum, 3 tunnel leaks, and 4 patients with fever on postoperative day one. Pneumoperitoneum needing decompression and postoperative fever were more prevalent in the standard technique group. CONCLUSIONS As POEM is becoming more common for the treatment of achalasia, refinements of the technique and instruments used are valuable. We compared our experience of the standard technique to our bottom-up technique and found the latter to be equally effective as well as safer, faster, and easier. We, therefore, suggest considering performing POEM in this technique.

Abstract
BACKGROUND Although the link between achalasia and morbid obesity is unclear, the reported prevalence is 0.5-1% in this population. For bariatric surgery patients, optimal type and timing of achalasia intervention is uncertain. METHODS Patient charts from a single academic institution were retrospectively reviewed. Between 2012 and 2019, 245 patients were diagnosed with achalasia, 13 of whom underwent bariatric surgery and were included. Patients were divided into two groups depending on the timing of their achalasia diagnosis and bariatric surgery. Groups were compared in terms of type and timing of intervention as well as treatment response. RESULTS Group 1 included 4 patients diagnosed with achalasia before bariatric surgery. Three had laparoscopic Heller myotomy (LHM) and 1 had a per oral endoscopic myotomy (POEM). These patients had laparoscopic gastric bypass (LGB) within 5 years of achalasia diagnosis. Postoperatively, 1 had severe reflux with regurgitation necessitating radiofrequency energy application to the lower esophageal sphincter. All had relief from dysphagia. Group 2 included 9 patients diagnosed with achalasia after bariatric surgery. Achalasia subtypes were evenly distributed. Initial operations were: 5 LGB, 2 laparoscopic sleeve gastrectomy (LSG), 1 duodenal switch (DS), 1 lap band. One LSG patient was converted to LGB concurrently with LHM. On average, achalasia was diagnosed 8.3 years after bariatric surgery. Achalasia interventions included: 1 pneumatic dilation, 1 Botox injection, 1 POEM, 6 LHM. While LHM was the most common procedure, 4 of 6 patients experienced recurrent dysphagia, one of whom required esophagectomy. CONCLUSIONS Achalasia is a challenging problem in the bariatric surgery population. Recurrent symptoms are common. Patients treated for achalasia after bariatric surgery tended to have worse symptom resolution than those diagnosed prior to bariatric surgery. Additional prospective studies are needed to elucidate whether interventions for achalasia should be performed concurrently or in a particular sequence for optimal results.

Abstract
The aim of this study is to design an implantable Lower Esophageal Sphincter (LES) stimulator connected and controlled by an Android Bluetooth for the treatment of the gastroesophageal reflux disease (GERD). Then the animal experiments are carried out to evaluate the function of the system. The LES stimulator is composed of an external controller, an Android application (APP) via a smart phone and an implantable electronic device (IED). The external controller is designed to receive the settings parameters information sent by the Android APP via a Bluetooth module, and then is programmed to generate specific electrical stimulation pulses to the LES. The Android APP controls the start and stop of stimulation and the settings of stimulation parameters. The in vivo IED consists of a bipolar stimulating lead, a bipolar head connector and a receiving module. The bipolar stimulating lead is constructed of biocompatible materials: platinum-iridium electrodes which are coated with parylene and an outer silicone rubber sheathing. The size of the receiving module has been significantly decreased to 20×20×2 mm3, which is packaged by polydimethylsiloxane (PDMS) and proposed to deliver stimulation pulses from the external controller to the implantable lead. The one-month implantation experiment on rabbits has been performed to evaluate the LES stimulator. The results indicate that the proposed LES stimulator meets the requirements of the functions, effectiveness and safety.

Abstract
BACKGROUND Postsurgical gastroparesis is recognized as a gastrointestinal dysfunction syndrome following foregut surgery. Gastric peroral endoscopic myotomy (G-POEM) is suggested as a minimally invasive therapy for gastroparesis. But the long-term efficacy and safety of G-POEM in treating postsurgical gastroparesis are rarely explored. METHODS The primary outcomes included the symptomatic improvement based on gastroparesis cardinal symptoms index (GCSI) and the improvement of gastric emptying. The secondary outcomes included the improvement of gastroesophageal reflux symptoms and complications of G-POEM. RESULTS The severity of postsurgical gastroparesis was not associated with the onset time and the course of the disease. G-POEM significantly reduced GCSI throughout the follow-up period (p < 0.0001). For different anastomotic site, a significant improvement of GCSI was found at 6 month post-G-POEM (F4,165 = 74.18, p < 0.0001). Subscale analysis of GCSI showed that nausea/vomiting, post-prandial fullness/early satiety, and bloating were improved significantly at 6-month post-G-POEM (p < 0.0001, respectively). Half-emptying and whole-emptying time were significantly shortened in patients with different anastomotic site post-G-POEM (half-emptying time: F3,174 = 65.44, p < 0.0001; whole-emptying time: F3,174 = 54.85, p < 0.0001). The emptying of ioversol was obviously accelerated after G-POEM. GCSI wasn't related to pyloric length, pyloric diameter, and thickness of pyloric wall. GERDQ was also used to evaluate the clinical efficacy of G-POEM. For each time points, GERDQ didn't differ significantly in patients with different anastomotic site (F4,104 = 0.8075, p = 0.5231). For patients with different anastomotic site, GERDQ was improved significantly at different time points (F4,104 = 59.11, p < 0.0001). The higher the esophageal anastomotic site was, the faster G-POEM improved the symptoms of gastroesophageal reflux. No one required re-hospitalization for any complication. CONCLUSION G-POEM is a minimally invasive therapy with long-term effectiveness and safety in treating postsurgical gastroparesis.

Abstract
Approximately 30% of all affected patients suffering from gastroparesis do not respond to any available treatment modality. Gastric peroral endoscopic myotomiy (G-POEM, antropyloromyotomy) represents a new principle of therapy. In this single center study, G-POEM showed a high technical success rate with a very low procedural complication rate. However, the clinical response beyond a short-term post-interventional improvement did not succeed in a single patient. The heterogeneity of the clinical picture, which represents a spectrum of different pathophysiological, etiological and clinical characteristics, still requires a therapy tailored to the individual patient. G-POEM should be considered especially in patients with pylorus-dominant gastroparesis.

Abstract
An 11-year-old, neutered female, Labrador retriever dog was presented with a history of intractable vomiting, regurgitation, and coughing. Computed tomography (CT) imaging identified marked hypertrophy of the distal esophagus with a suspicion of distal esophageal achalasia, based on the observation of a "bird beak" appearance. This was later confirmed on a fluoroscopic swallow study. Marked hypertrophy of the gastric pylorus was also identified on CT imaging, and polypoid gastric mucosal hyperplasia was diagnosed based on the gross endoscopic appearance combined with gastric histopathology. Secondary aspiration pneumonia was diagnosed based on the results of CT imaging, bronchoscopy and bronchoalveolar lavage fluid analysis. Medical therapy alone failed to elicit any significant improvement, but clinical resolution was achieved following surgical intervention comprising Ventral Heller myotomy, Dor's fundoplication, and pyloroplasty.

Abstract
INTRODUCTION Esophageal achalasia is a rare condition, characterised by progressive dysphagia due to innervation of the esophageal muscles and non-relaxation of the lower esophageal sphincter. The standard of care of surgical treatment is laparoscopic Heller myotomy. POEM-Peroral endoscopic myotomy is a new approach offering incision-less and selective myotomy. AIMS This study aims to describe our experience and outcomes using this new surgical technique. METHODS We performed a retrospective study using prospectively maintained data of all achalasia patients treated by POEM in our department. Data collected included patient demographics, gender, age, BMI, data related to the disease course in addition to data related to the surgery itself as well as both short and long term post-operative follow-up. RESULTS Over the course of five years we performed 86 POEM operations, demonstrating a decrease in the Eckardt score from a mean of 8.87 to a mean of 0.7 in the immediate postoperative. Mean operative time was 86 minutes, with mean hospitalization time of 4 days. Intraoperative complications included 2 mucosal injuries while post-operative complications included 4 incomplete mucosal closures, 5 recurrent dysphagia and 5 patients with reflux requiring medical therapy. CONCLUSIONS In the last decade, POEM procedure is being performed worldwide and has been performed in our department for the past five years. Our results show a success rate of 94.2% with minor complications. In our institution, as in many institutions globally, POEM is the preferred method for treating achalasia.

Abstract
Achalasia is a rare idiopathic disease, associated with significant morbidity and negative impact on life quality. The disorder is characterized by impairments in the esophageal motility and loss of the lower esophageal sphincter (LES) relaxation. Achalasia symptoms include dysphagia, regurgitations, chest pain, vomiting and weight loss. Diagnosis of achalasia is based on an appropriate clinical presentation and typical findings on complementary tests. These tests include endoscopy showing a dilated esophageal lumen containing fluid or food, High-resolution manometry (HRM) shows evidence of obstruction at the gastro-esophageal junction and motility failure, and barium swallow shows esophageal dilation and distal narrowing. The recent advent of HRM has permitted more precise diagnosis of achalasia and three subtype designations, based on the pattern of esophageal motility disorders, as per the Chicago Classification. Treatment options include: drugs, endoscopic by means of Botox injection or balloon dilation, and the traditional surgery, laparoscopic Heller myotomy (LHM). The new advent in treatment is the novel per-oral endoscopic myotomy (POEM), a less invasive therapy, approaching the traditional LHM. Since the first POEM procedure performed in 2008, massive amounts of evidence are accumulating regarding the high efficacy and safety profiles of POEM, introducing it as an excellent first line treatment. The current review discusses the diagnosis and management of achalasia, with special highlights on the recent progress of HRM and POEM.

Abstract
Achalasia cardia is an esophageal motility disorder rarely reported in children and more so in young infants. Common clinical presentations include vomiting, dysphagia, regurgitation, recurrent pulmonary aspiration and failure to thrive. Diagnosis is made by barium swallow study and esophageal manometry, which is the gold standard test. Pharmocological management and endotherapy often fails and results in recurrence of symptoms. Laparoscopic Hellers myotomy, with or without anti-reflux procedure is the standard treatment of choice for children. Per-oral endoscopic myotomy is utilized for treatment of achalasia in adults, but its safety, efficacy, and feasibility is not studied in children.

Abstract
Electrical stimulation therapy (EST) of lower esophageal sphincters (LES) is a new technique for the treatment of gastroesophageal reflux disease (GERD). In this paper, an implantable LES stimulator with wireless power transmission is proposed for the treatment of GERD. The LES stimulator is composed of an implantable pulse generator (IPG), an external controller, and a wireless power transmission module. The IPG, whose area is 31×21 mm2, is designed to generate voltage-regulated constant-current stimulation pulses. The external controller allows for wireless programming of the IPG via a Bluetooth Low Energy (BLE) module. The wireless power transmission module provides power for the IPG. According to the measurement of output stimulus waveforms, the proposed LES stimulator is capable of delivering electrical stimulations with a current ranging between 0 and 8 mA. To evaluate the safety and efficacy of the proposed LES stimulator, experiments were performed on 12 male New Zealand white rabbits. Esophageal manometry was performed before and after the procedure and the LES pressure (LESP) has been recorded. The mean LESP is increased significantly in the stimulation group than the sham group (stimulation group: 9.25±1.24 mmHg vs 13.99 ±1.28 mmHg, p<;0.05; sham group: 9.00±1.22 mmHg vs 9.23±1.27 mmHg, p=0.267). The results show that the electrical stimulation delivered by the LES stimulator can safely and effectively increase resting LES pressure in acute animal models, suggesting that the implantable LES stimulator is a perspective approach for treating GERD in clinics.

Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) represents one of the most common gastrointestinal disorders, but is still a challenge to cure. Proton pump inhibitors (PPIs) are currently the GERD's standard treatment, although not successful in all patients; some concerns have been raised regarding their long term consumption. Recently, some studies showed the benefits of inspiratory muscle training in increasing the lower esophageal sphincter pressure in patients affected by GERD, thereby reducing their symptoms. MATERIALS AND METHODS Relevant published studies were searched in Pubmed, Google Scholar, Ovid or Medical Subject Headings using the following keywords: "GERD" and physiotherapy", "GERD" and "exercise", "GERD" and "breathing", "GERD and "training". RESULTS At the end of our selection process, four publications have been included for systematic review. All of them were prospective controlled studies, mainly based on the training of the diaphragm muscle. GERD symptoms, pH-manometry values and PPIs usage were assessed. CONCLUSIONS Among the non-surgical, non-pharmacological treatment modalities, the breathing training on diaphragm could play an important role in selected patients to manage the symptoms of GERD.

Abstract
Aim of the present study is the presentation of our experience in conservative treatment of coin-shaped, ingested foreign bodies in lower esophagus and the consideration about the indications of this method's appliance in clinical practice. From 2011 to 2014, 79 children in total (45 male - 34 female), aged from 8 months to 13 years (average 4.8 years) were admitted to our Department due to foreign body ingestion. In 21/79 patients the foreign body lodged in the esophagus, in 9 in the upper and in 12 in the lower esophagus. Cases of pre-existing esophageal stricture or of esophageal obstruction, due to sharp or linear foreign bodies or disk battery, were excluded. Finally, our study group consisted of 11 patients, aged from 10 months to 10 years (aver- age 4.6 years). The average time elapsed from the ingestion of the foreign body until the admission of the child in the Emergency Department was 4 hours. Young patients were administered suppository form of hyoscine-N-butylbromide, followed by repetition of radiograph 6 hours later. In 9 cases the ingested foreign body passed to the stomach within the first six hours, while in 2 cases no alteration of its position was noted, thus endoscopic removal followed. In these 9 cases the foreign body passed through the gastrointestinal (GI) tract and was excreted within the next 1-3 days. Smooth muscle relaxation of the lower esophageal sphincter after administration of hyoscine-N-butylbromide was successful in 82% of our patients, while the success rate in relevant publications ranges from 20 to 42%. In conclusion, it is worth noting that the pharmaceutical relaxation of the lower esophageal sphincter is a safe alternative method of treatment in cases of foreign bodies lodged in the lower esophagus, except for linear or sharp objects or coin batteries. Given that the majority of hospitals in Northern Greece lacks of pediatric gastroenterologists, while endoscopic intervention - when indicated - should be conducted early after admission, it is obvious that the proposed method becomes essential.

Abstract
The esophagogastric junction is a muscle, not a mucosal, junction. The boundary of the esophagus is at the upper esophageal sphincter and lower esophageal sphincter (LES) at the oral and anal ends, respectively. The distal end of the LES is the esophagogastric junction. Fine palisade vessels occur in the mucosa above the LES, and the esophagogastric junction is at the distal end of this palisade zone. The esophagogastric junction is defined as the part changing into the lumen seen in radiographic, examination or in surgically resected specimens. It is extremely difficult to identify the esophagogastric junction pathologically, requiring special effort.

Abstract
BACKGROUND In 2012 the United States Food and Drug Administration approved implantation of a magnetic sphincter to augment the native reflux barrier based on single-series data. We sought to compare our initial experience with magnetic sphincter augmentation (MSA) with laparoscopic Nissen fundoplication (LNF). METHODS A retrospective case-control study was performed of consecutive patients undergoing either procedure who had chronic gastrointestinal esophageal disease (GERD) and a hiatal hernia of less than 3 cm. RESULTS Sixty-six patients underwent operations (34 MSA and 32 LNF). The groups were similar in reflux characteristics and hernia size. Operative time was longer for LNF (118 vs 73 min) and resulted in 1 return to the operating room and 1 readmission. Preoperative symptoms were abolished in both groups. At 6 months or longer postoperatively, scores on the Gastroesophageal Reflux Disease Health Related Quality of Life scale improved from 20.6 to 5.0 for MSA vs 22.8 to 5.1 for LNF. Postoperative DeMeester scores (14.2 vs 5.1, p=0.0001) and the percentage of time pH was less than 4 (4.6 vs 1.1; p=0.0001) were normalized in both groups but statistically different. MSA resulted in improved gassy and bloated feelings (1.32 vs 2.36; p=0.59) and enabled belching in 67% compared with none of the LNFs. CONCLUSIONS MSA results in similar objective control of GERD, symptom resolution, and improved quality of life compared with LNF. MSA seems to restore a more physiologic sphincter that allows physiologic reflux, facilitates belching, and creates less bloating and flatulence. This device has the potential to allow individualized treatment of patients with GERD and increase the surgical treatment of GERD.

Abstract
Although laparoscopy-assisted proximal gastrectomy (LAPG) with esophagogastrostomy for early gastric cancer (EGC) is technically feasible and oncologically safe, it has not been popularized because of the frequent occurrence of reflux esophagitis associated with loss of the lower esophageal sphincter (LES). Herein, we present surgical outcomes in patients with LES-preserving LAPG (LES-p LAPG), which may contribute to protecting against postoperative gastroesophageal reflux or stricture in the treatment of proximal EGC. From November 2009 to May 2010, LES-p LAPG was performed in nine patients with clinical EGC, located at the proximal one-third of the stomach with the upper margin of the tumor 3-4 cm from the esophagogastric junction. After the resection of the proximal stomach with D1 + β lymph node dissection, gastrogastrostomy was performed using a 25-mm circular stapler through a mini-laparotomy wound at the epigastrium. The median operating time was 137.5 min (range 120-180). The median number of retrieved lymph nodes and length of the proximal resection margin were 27 (range 7-49) and 2.4 cm (range 0.7-5), respectively. The postoperative complications included one gastrogastrostomy stricture and one case of leakage, which were managed by endoscopic balloon dilation and conservative treatment, respectively. None of the patients suffered from symptoms of reflux esophagitis during the follow-up period (median 15 months; range 8-28 months). This technique of LES-p LAPG for the treatment of proximal EGC could be a simple, safe, and useful technique to prevent esophageal reflux or stricture. This technique requires prospective validation.

Abstract
OBJECTIVE Through monitoring esophageal dynamic change, and detection of laryngopharyngeal reflux(LPR) and gastroesophageal reflux events,to discuss the relationship of vocal cord polyps with laryngopharyngeal reflux. METHODS Thirty-two patients with vocal cord polyps were diagnosed by electronic laryngoscopy in Nanfang Hospital between October 2011 to May 2012. This study applied high-resolution esophageal manometry (HRM) and ambulatory 24-hour multichannel intraluminal impedance-pH monitoring (MII-pH) to obtain the upper esophageal sphincter(UES) and lower esophageal sphincter pressure, characteristics of sectional esophageal motility; laryngopharyngeal reflux (LPR)and gastroesophageal reflux events, as well as the reflux properties of substances. Sixteen healthy volunteers were recruited as normal controls. RESULTS UES relaxation duration, duration of UES relaxation time, UES relaxation recovery time and mean length of LES were all shorter than those of the control group (t were 2.244, 2.624, 2.310 and -2.397, P < 0.05). There were 40.6% (13/32) LPR and 50.0% (16/32) gastroesophageal reflux found in vocal polyp patients. Median number (M [P25; P75]) of laryngopharyngeal acid reflux events were 0.5[0.0;3.5] and 0.0[0.0;0.0] in vocal polyp group and the controls, median mean time of laryngopharyngeal acid exposure 0.1[0.0;1.7] and 0.0[0.0;0.0] min, median clearance time of laryngopharyngeal acid were 3.5[0.0;53.5] and 0.0[0.0;0.0] s, median scores of DeMeester were 14.8[1.6;31.3] and 1.8[1.1;4.1] and median frequency of total liquid reflux episodes were 46.5[25.3;69.0] and 32.5[20.0;36.3], respectively. The median numbers of laryngopharyngeal acid reflux events, time of acid exposure, time of acid clearance, DeMeester scores and frequency of total liquid reflux episodes were increased or higher in vocal polyp group than those in the controls (z were 2.481, 2.767, 2.767, 2.344 and 1.980, P < 0.05). CONCLUSIONS There are upper esophageal sphincter and Lower esophageal sphincter dismotility in vocal polyp patients with LPR. LPR events were dominated by acid reflux in upright position.Esophageal dynamic disfunction and LPR should be considered in the study of the pathogenesis of vocal cords polyps.

Abstract
BACKGROUND When an esophageal stent is placed through the lower esophageal sphincter (LES), gastroesophageal reflux symptoms may persist despite high-dose proton pump inhibitor therapy. A recently developed, short segment, uncovered nitinol stent with a tricuspid-like valve can be placed inside a previously placed esophageal stent. OBJECTIVE To evaluate the technical feasibility and safety of a reflux control system (RCS) in distally placed esophageal stents. DESIGN A prospective case series. SETTING Two tertiary-care referral centers. PATIENTS This study involved 10 patients who had an "open" stent placed through the LES and 1 patient with severe bile reflux after esophagojejunostomy. INTERVENTION Placement of an RCS with fluoroscopic and (in selected cases) endoscopic guidance, from April to October 2010. MAIN OUTCOME MEASUREMENTS Technical success of RCS placement and complications. RESULTS Placement of an RCS was successful on the first attempt in all patients; complete expansion to the wall of the host stent was confirmed by fluoroscopy in all cases. In 3 patients, the host stent migrated in <1 month with the RCS still inside. In 8 patients, the RCS was in place for a median of 134 days (range 33-225 days). Three patients died because of malignant disease progression. Eight RCSs were removed endoscopically, together with the host stent without complications. RCS migration did not occur. LIMITATIONS Small number of patients, nonrandomized design, lack of pH measurements. CONCLUSION Placement of an RCS in a host stent is technically feasible and safe. An RCS can be considered in symptomatic patients with open esophageal stents to prevent gastroesophageal reflux.

Abstract
BACKGROUND/AIMS Important lesions related to gastroesophageal reflux disease (GERD) are located around the gastroesophageal junction (GEJ). This study examined the distribution of endoscopic findings around the GEJ and elucidated their relationship to each other and esophageal manometric features. METHODS Endoscopic data were collected prospectively from 2,450 consecutive diagnostic upper gastrointestinal endoscopies. The presence and degree of hiatal hernia (HH), columnar-lined esophagus (CLE), and reflux esophagitis (RE) were recorded. Esophageal manometric data were collected from 181 patients. RESULTS The prevalence of HH, CLE, and RE was 9.8, 18.8, and 9.9%, respectively. Of all HH and CLE cases, 62.8 and 98.9%, respectively, were of the short-segment variety. Of all RE cases, 95.0% were mild. Younger age, male gender, the presence of HH, and a higher gastroesophageal flap valve (GEFV) grades were associated with the presence of RE. Increased ZAP grades were associated with increased prevalence and grades of HH, CLE, and RE. Higher GEFV grades were associated with increased prevalence and grades of HH, CLE, and RE. Lower esophageal sphincter pressure (LESP) decreased in patients with HH or RE compared to those without HH or RE. CONCLUSIONS Endoscopic findings around the GEJ revealed that a substantial proportion of our patients showed features potentially related to GERD. In combination with other recent reports, our study implies that Korea is no longer a very-low-prevalence area of GERD, although it may predominate in silent or milder forms.

Abstract
BACKGROUND/AIMS Vagal nerve and pylorus-preserving nearly total gastrectomy reconstructed by interposition of a jejunal J pouch (hereinafter called NTGP) is a function-preserving operation for early gastric cancer. However, some patients after NTGP have suffered from postprandial food stasis in the substitute stomach, and postprandial stasis leads to abdominal symptoms. To clarify the clinical effect of mosapride citrate (hereinafter called MS) for prevention of food stasis in the substitute stomach for patients after NTGP, we studied the clinical effects of MS before and after administration of MS. METHODOLOGY In a total of 24 patients (18 males, 6 females; aged 44-70 years, average 58.1 years) during 5 years after NTGP for early gastric cancer (D1 lymph node dissection, curability A), the relationship between their postoperative quality of life (QOL) and emptying function of the substitute stomach (hereinafter called EFS) was compared using a radioisotope method before MS therapy and after MS therapy at an oral dose of 15mg/day for 3 months. RESULTS The interviews showd that after MS therapy, patients had more evident appetite and ate more food with a slight increase in body weight (0.52Kg) compared with patients before MS therapy. Before and after MS therapy, patients had no early dumping symtoms, while patients after MS therapy clearly had fewer symptoms such as reflux esophagitis, nausea, and abdominal pain compared with before MS therapy. After MS therapy, patients also had significantly decreased abdominal fullness compared with before MS therapy (p = 0.0046). Endoscopically, we found reflux esophagitis in 4 patients before MS therapy but in no patients after MS therapy. All patients before MS therapy showed residual contents in the substitute stomach, but only 10 patients after MS therapy showed residual contents in the substitute stomach. There was a significant difference between before and after MS therapy (p = 0.0016). Regarding EFS, the time to 50% residual rate before MS therapy (98.7 +/- 13.0 min) was significantly slower than that after MS therapy (83.2 +/- 13.8 min) (p = 0.0134). After MS therapy (37.0 +/- 4.9%), the residual rates at 120 minutes were significantly decreased compared with patients before MS therapy (44.8 +/- 5.3%) (p = 0.0028). Patients after MS therapy clearly had improved stasis of substitute stomach compared with before MS therapy. CONCLUSIONS It was considered that MS therapy subsequently improves abdominal fullness due to the postprandial food stasis in the substitute stomach, contributing to the improvement of QOL of patients after NTGP.

Abstract
BACKGROUND The success of fundoplication surgery varies widely; furthermore, complications after fundoplication can be common. We introduced a new device to treat GERD: biomechanical augmentation of the lower esophageal sphincter (LES) by use of a magnetic reinforcing appliance. OBJECTIVES The aim was to determine whether a magnetic appliance could safely increase LES pressure, maintain a closed sphincter except during swallowing and belching, and increase the gastric yield pressure in a porcine model. DESIGN Ex vivo work-assessed design variables that would augment the reflux barrier yet still preserve swallow function. Porcine acute and chronic (44 weeks) postimplant studies were also performed. A single animal underwent planned device removal. MAIN OUTCOME MEASUREMENTS Gastric yield pressure, animal behavior, endoscopy, barium studies, balloon expansion studies, esophageal manometry, and histology. RESULTS Gastric yield pressure correlated with increasing magnetic forces (R(2)=0.5608, P< .001). The sphincter augmentation device was safe in all animals, with no observed effect on eating behavior and normal weight gain. The mucosa of the esophagus appeared normal at all intervals, and there was no device migration or significant tissue inflammation. The average LES pressure rose after implantation (P< .005). Balloon and barium studies demonstrated a closed sphincter with normal opening of the gastroesophageal junction during swallowing. CONCLUSIONS Magnetic sphincter augmentation is a novel approach for the treatment of GERD. This study demonstrates the safety and feasibility of such a device in a porcine model. Further investigation of this device for the treatment of GERD in humans seems warranted.

Abstract
BACKGROUND AND STUDY AIMS The most permanent method of treating achalasia is a surgical myotomy. Because of the requirement for a mucosal incision and the risk of perforation, this procedure has not generally been approached endoscopically. We hypothesized that we could perform a safe and robust myotomy by working in the submucosal space, accessed from the esophageal lumen. MATERIALS AND METHODS Four pigs were used for this experiment. Baseline lower esophageal sphincter (LES) pressures were recorded and the pigs underwent upper endoscopy using a standard endoscope. A submucosal saline lift was created approximately 5 cm above the LES and a small nick was made in the mucosa in order to facilitate the introduction of a dilating balloon. After dilation, the scope was introduced over the balloon into the submucosal space and advanced toward the now visible fibers of the LES. The circular layer of muscle was then cleanly incised using an electrocautery knife in a distal-to-proximal fashion, without complications. The scope was then withdrawn back into the lumen and the mucosal defect was closed with endoscopically applied clips. The entire procedure took less than 15 minutes. Manometry was repeated on day 5 after the procedure and the animals were euthanized on day 7. RESULTS LES pressures fell significantly from an average of 16.4 mm Hg to an average of 6.7 mm Hg after the myotomy. The necropsy examinations revealed no evidence of mediastinitis or peritonitis. CONCLUSIONS Endoscopic submucosal esophageal myotomy is feasible, safe, and effective in the short term. It has the potential for being useful in patients with achalasia. The submucosal space is a novel and potentially important field of operation for endoscopic procedures.

Abstract
A 6-year-old boy presented with nocturnal cough of 8 months duration. Upper gastrointestinal endoscopy (UGIE) showed an esophagogastric polyp and esophagitis. The 24 hours ambulatory pH recording revealed moderate gastro esophageal reflux (GER) and esophageal manometry demonstrated hypotensive lower esophageal sphincter (LES). A diagnosis of gastroesophagel reflux disease (GERD) with hypotensive LES and inflammatory esophagogastric polyp was made. The child's symptoms subsided with antireflux treatment.

Abstract
Although the etiology of gastroesophageal reflux disease (GERD) is multifactorial, the pathophysiology of the disease in morbidly obese patients remains incompletely understood. The aims of this study were to compare in morbidly obese (body mass index (BMI) > or =35) and nonmorbidly patients (BMI <35) with GERD: (a) lower esophageal sphincter (LES) profile; (b) esophageal body function; and (c) esophageal acid exposure. We reviewed esophageal manometry and ambulatory 24-hour pH monitoring studies of 599 consecutive patients with GERD (DeMeester score >14.7). Patients were divided into two groups according to the BMI: (1) 520 patients (86.8%) with BMI <35 and (2) 79 patients (13.2%) with BMI > or =35. While the DeMeester score was not different between the two groups, morbidly obese patients had higher LES pressure and higher amplitude of peristalsis in the distal esophagus (DEA). Among these patients, LES and DEA pressures were often hypertensive. A linear regression model showed that BMI, LES pressure, LES abdominal length, and DEA were independently associated with the DeMeester score. These data showed that: (a) BMI was independently associated to the severity of GERD; and (b) in most morbidly obese patients with GERD, reflux occurred despite normal or hypertensive esophageal motility. These findings show that the pathophysiology of GERD in morbidly obese patients might differ from that of nonobese patients, suggesting the need for a different therapeutic approach.

Abstract
BACKGROUND/AIMS Persistent postoperative dysphagia diminishes the good effect of laparoscopic anti-reflux surgery. An excessive increase of the intraoperative lower esophageal sphincter pressure (LESp) is supposed to be related to the persistent postoperative dysphagia and its knowledge could lead to the modification of the surgical technique followed by improved clinical outcomes. This study aims to describe the relation between the intraoperative LESp increase and the incidence of postoperative dysphagia and to find whether a combination of intraoperative manometry and mechanical calibration of the wrap is able to decrease the incidence of the persistent postoperative dysphagia. METHODOLOGY The randomized, prospective, two-branch study included 39 patients suffering from symptoms of gastroesophageal reflux disease. All patients underwent pre- and postoperative manometry, 24-hour pH-metry and laparoscopic anti-reflux surgery. The intraoperative LESp was measured in the study arm only. RESULTS A higher incidence of persistent postoperative dysphagia was revealed in patients with the intraoperative LESp increase more than 15 mmHg. This complication was not found in patients with the LESp increase under 8 mmHg with no impact on the efficacy of the surgery. The combination of the intraoperative manometry and the mechanical calibration of the wrap seems to bring the benefit only to a small number of the patients. CONCLUSIONS According to our results, the intraoperative LESp measurement proved to be a useful supplementary method which was easy to perform, and which enables a modification of the surgical technique to decrease the incidence of the persistent postoperative dysphagia.

Abstract
BACKGROUND Alterations in esophageal motility may occur after placement of an adjustable gastric band as treatment for morbid obesity, near the gastro-esophageal junction. It causes an outlet obstruction, especially during follow-up after the band is filled. METHODS 29 morbidly obese patients underwent conventional manometry preoperatively, 6 weeks postoperatively before and after filling the band and at 6 months postoperatively. A questionnaire was used to assess upper gastrointestinal symptoms during follow-up. RESULTS After band placement, there was a significant increase in lower esophageal sphincter (LES) end-expiratory pressure at 6 weeks with an empty band: 1.3 (0.9-1.9) kPa (median (interquartile range) (P=0.003), 6 weeks with a filled band: 2.1 (1.5-2.8) kPa (P=0.0001), and at 6 months: 1.5 (1.3-1.9) kPa (P=0.001), compared to the preoperative pressure: 0.8 (0.6-1.3) kPa. Also after band placement, the high pressure zone length increased (preop 5.0 (4.3-6.0) cm vs 6 weeks 6.0 (5.0-6.5) cm (P=0.003). The propagation of peristaltic contractions was not significantly altered after band placement. Heartburn decreased 6 weeks postoperatively (P=0.04) but increased at 6 months. Heartburn at 6 months was correlated with pouch formation (0.667; P<0.01). CONCLUSION Adjustable gastric band placement causes an increase in LES pressure and length of the high pressure zone. It decreases reflux symptoms in the short-term, but this effect appears not to be related to an effect on LES pressure or length. Pouch formation increases reflux symptoms without having any relationship to LES pressure and length. Band placement in the short-term does not disturb propagation of esophageal contractions.
