Abstract
BACKGROUND Gastric per-oral endoscopic myotomy (G-POEM) is an innovative treatment that has become increasingly utilized for patients with refractory gastroparesis. The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness of G-POEM for the treatment of gastroparesis. METHODS Individualized search strategies were developed through February 2021 in accordance with the PRISMA and MOOSE guidelines. This meta-analysis was performed by calculating pooled proportions and mean difference preprocedure and postprocedure with rates estimated using random effects models. Measured outcomes included technical success, clinical success, improvement in gastroparesis cardinal symptom index (GCSI), change in gastric emptying rate, alterations in impedance planimetry (functional lumen imaging probe [FLIP]) assessment, and adverse events. RESULTS A total of 20 studies (n=797 patients; 67.41% female) were included. The mean age was 48.92±11.61 y, with an average duration of 4.24±1.11 y since gastroparesis diagnosis. Technical success was 98.47% [(95% CI: 97.14, 99.19);I2=0.00] with a mean myotomy length of 3.78±1.16 cm. In terms of clinical success, mean preprocedure GCSI scores were 3.38±0.37 and improved significantly postprocedure [weighted mean difference -1.56 (95% CI: -1.89 to -1.24); I2=82.53; P<0.001]. Gastric retention after 4 hours demonstrated ~50% improvement (preprocedure 43.08±9.24% versus postprocedure 22.97±10.19%; P<0.001). FLIP assessment with 40 mL and 50 mL balloons demonstrated a significant increase in diameter, distensibility index, and cross-sectional area postprocedure (all P<0.05). Procedure-associated adverse events occurred among 10.92% [(95% CI 5.09 to 19.32); I2=82.85] of patients. CONCLUSION G-POEM appears safe and highly effective for the treatment of patients with refractory gastroparesis regardless of symptom predominance or etiology.

Abstract
Gastric peroral endoscopic myotomy (G-POME) is an emerging minimally invasive endoscopic technique involving the establishment of a submucosal tunnel around the pyloric sphincter. In 2013, Khashab et al used G-POME for the first time in the treatment of gastroparesis with enhanced therapeutic efficacy, providing a new direction for the treatment of gastroparesis. With the recent and rapid development of G-POME therapy technology, progress has been made in the treatment of gastroparesis and other upper digestive tract diseases, such as congenital hypertrophic pyloric stenosis and gastric sleeve stricture, with G-POME. This article reviews the research progress and future prospects of G-POME for the treatment of upper digestive tract gastrointestinal diseases.

Abstract
Gastroparesis is a common complaint among patients with diabetes. Symptoms tend to improve following successful pancreas transplantation (PTx), but persist despite euglycemia in a subset of patients. We aimed to assess the benefit of gastric peroral endoscopic myotomy (G-POEM) in persistent gastroparesis following PTx. This was a single center retrospective review of all patients who underwent G-POEM for persistent gastroparesis following PTx. Patient demographics, pre and post procedure perception of symptom severity according to the patient assessment of upper gastrointestinal symptoms severity index (PAGI-SYM), gastroparesis cardinal symptom index (GCSI) score, and 36-item short form survey (SF36) score along with gastric emptying scintigraphy (GES) were analyzed. Seven PTx recipients underwent G-POEM for persistent gastroparesis symptoms. The majority were female. All reported nausea/vomiting, abdominal pain, bloating, and post prandial fullness prior to G-POEM. The post procedure survey scores improved in all patients although this was not significant. The improvement in gastric emptying on GES was statistically significant. G-POEM is a relatively new treatment option for gastroparesis. While it requires specialized proceduralist and training, we have documented improvement in the management of symptoms. With increasing experience, we anticipate more significant benefit in post PTx patients with persistent symptoms of gastroparesis undergoing G-POEM.

Abstract
Our review delves into the realm of peroral endoscopic myotomies (POEMs) in the upper gastrointestinal tract (UGT). In recent years, POEMs have brought about a revolution in the treatment of UGT motility disorders. Esophageal POEM, the first to be introduced, has now been validated as the primary treatment for achalasia. Subsequently developed, G-POEM displays promising results in addressing refractory gastroparesis. Over time, multiple endoscopic myotomy techniques have emerged for the treatment of Zenker's diverticulum, including Z-POEM, POES, and hybrid approaches. Despite the well-established efficacy outcomes, new challenges arise in the realm of POEMs in the UGT. For esophageal POEM, the future scenario lies in customizing the myotomy extent to the minimum necessary, while for G-POEM, it involves identifying patients who can optimally benefit from the treatment. For ZD, it is crucial to validate an algorithm that considers various myotomy options according to the diverticulum's size and in relation to individual patients. These challenges align with the concept of precision endoscopy, personalizing the technique for each subject. Within our text, we comprehensively examine each myotomy technique, analyzing indications, outcomes, and adverse events. Additionally, we explore the emerging challenges posed by myotomies within the context of the evolving field of precision endoscopy.

Abstract
BACKGROUND Post-lung transplant gastroparesis is a frequent debilitating complication of lung transplant recipients, as it can increase the risk for gastro-esophageal reflux disease and subsequent graft dysfunction. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of GPOEM in lung transplant patients with refractory gastroparesis. METHODS The present systematic review and meta-analysis wer performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. We selected studies that analyzed the gastroparesis cardinal symptom index (GCSI) before and after the procedure to verify the efficacy of GPOEM. Random-effects model was used and the analysis was performed with STATA 17. RESULTS Four observational studies (one conference abstract) with 104 patients were included in the meta-analysis. Prior treatments for gastroparesis included prokinetic agents and botulinum toxin in 78% (78/104) and 66.7% (66/99), respectively. Pooled estimate for clinical efficacy of GPOEM was 83% (95% CI 76%-90%). The pooled mean reduction in GCSI following the procedure was - 2.01 (- 2.35, - 1.65, p = 0.014). Three studies reported statistically significant improvement of gastro-esophageal retention or emptying in the post-GPOEM period. 30-day post-operative complications included minor or major bleeding (11.6%), severe reflux (1.2%), and pyloric stenosis (1.2%) requiring re-intervention. 90-day all-cause mortality was 2.6% with one patient dying from severe allograft rejection. CONCLUSION Our study showed that GPOEM is an effective and safe strategy for lung transplant patients with refractory gastroparesis and should be considered as a therapeutic strategy in this population. Larger multicenter trials are needed in the future to further evaluate the effect of GPOEM on allograft function and rates of rejection.

Abstract
OBJECTIVES This meta-analysis aimed to systematically evaluate the efficacy of acupuncture in treating postsurgical gastroparesis syndrome (PGS) after thoracic or abdominal surgery. DESIGN Systematic review and meta-analysis. DATA SOURCES Twelve databases (PubMed, Embase, Cochrane Library Cochrane Central Register of Controlled Trials (CENTRAL), Medline (Ovid) (from 1946), Web of Science, EBSCO, Scopus, Open Grey, China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Scientific Journals Database (VIP) and China Biology Medicine disc (CBM)) and three registration websites (WHO International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, and Chinese Clinical Trial Registry (ChiCTR)) were searched from the inception to September 2022, and citations of the included literature were screened. ELIGIBILITY CRITERIA All randomised controlled trials addressing invasive acupuncture for PGS. DATA EXTRACTION AND SYNTHESIS Key information on the included studies was extracted by two reviewers independently. Risk ratio (RR) with 95% CI was used for categorical data, and mean difference with 95% CI for continuous data. The quality of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation. Outcomes were conducted with trial sequential analysis (TSA). RESULTS Fifteen studies with 759 patients met the inclusion criteria. Subgroup analyses revealed that compared with the drug group, the drug and acupuncture group had a greater positive effect on the total effective rate (TER) (nine trials, n=427; RR=1.20; 95% CI 1.08 to 1.32; P-heterogeneity=0.20, I2=28%, p=0.0004) and the recovery rate (RCR) (six trials, n = 294; RR = 1.61; 95% CI 1.30 to 1.98; P-heterogeneity=0.29, I2=19%, p<0.0001) of PGS after abdominal surgery. However, acupuncture showed no significant advantages in terms of the TER after thoracic surgery (one trial, p=0.13) or thoracic/abdominal surgery-related PGS (two trials, n = 115; RR=1.18; 95% CI 0.89 to 1.57; P-heterogeneity=0.08, I2=67%, p=0.24) and the RCR after thoracic/abdominal surgery (two trials, n=115; RR=1.40; 95% CI 0.97 to 2.01; P-heterogeneity=0.96, I2=0%, p=0.07). The quality of evidence for TER and RCR was moderate certainty. Only one study reported an acupuncture-related adverse event, in the form of mild local subcutaneous haemorrhage and pain that recovered spontaneously. TSA indicated that outcomes reached a necessary effect size except for clinical symptom score. CONCLUSION Based on subgroup analysis, compared with the drug treatment, acupuncture combined drug has significant advantages in the treatment of PGS associated with abdominal surgery, but not with thoracic surgery.

Abstract
Gastroparesis is a chronic and debilitating gastrointestinal disorder with few medical treatment options. Traditional surgical management has involved laparoscopic pyloromyotomy or gastric stimulation. In recent years, gastric peroral endoscopic myotomy (GPOEM) has become an attractive, less invasive option for patients with refractory gastroparesis. There is little information on the long-term clinical success of GPOEM in patients with refractory gastroparesis. This systematic review aims to evaluate the data on this procedure's long-term clinical efficacy and safety. A comprehensive literature review was done in PubMed, EMBASE, Ovid, and Google Scholar databases from the date of earliest entry in May 2017 up to August 15, 2022. The Gastroparesis Cardinal Symptom Index (GCSI) score, adverse reaction, and length of stay were analyzed. Eleven studies were eligible for inclusion (900 patients), seven of the studies were retrospective, while four were prospective. The GCSI is a 6-point Likert scale questionnaire that assesses improvement in gastroparesis. An average decrease of GCSI by 1 point compared to baseline GCSI for all patients (described as clinical success) was found in 662 patients out of 713 (92.8%) at one-year follow-up, 421 out of 460 (91.5%) at two-year follow-up, 270 out of 270 (100%) at three-year follow-up, and 102 out of 102 (100%) at four-year follow-up. Adverse events occurred in 62 out of 835 patients (in nine studies), with two of the most frequent being bleeding and mucosal tears. GPOEM is an effective and safe treatment option for patients with refractory gastroparesis, with symptom improvement noted up to four years postoperatively.

Abstract
The "third space endoscopy" or also called "submucosal endoscopy" is a reality we can transfer to our patients since 2010. Various modifications of the submucosal tunneling technique allow access to the submucosa or deeper layers of the gastrointestinal tract. In addition to peroral endoscopic myotomy for the treatment of achalasia, also called esophageal POEM, other variants have emerged that make it possible to treat different esophageal motility disorders, esophageal diverticula, subepithelial tumors of various locations, gastroparesis, reconnection of complete esophageal strictures or even thanks to exceptional endoscopists, pediatric disorders such as Hirschsprung's disease. Although some technical aspects are yet to be standardized, these procedures are becoming widespread worldwide and will likely become the standard treatment of these pathologies soon.

Abstract
Gastric peroral endoscopic pyloromyotomy (G-POEM or POP) is an endoscopic therapeutic modality for treatment of refractory gastroparesis. Since the first case reported in 2013, there are more than 200 papers published on G-POEM. In this narrative review, we summarize the short-term and long-term outcomes and review other important studies. The technical success rate is 100% and the short-term (within 1 year) success rate is about 50-80%. The procedure time is between 50 and 70 min while the average length of hospital stay was 2-3 days. The adverse event rate was around 10%. Few patients need further intervention. Three studies showed that at the 4-year follow-up, the response to G-POEM was durable, but there was a yearly recurrence rate of 13% or more. Redo G-POEM is feasible and can be of benefit for some patients. Most of the studies showed that long duration of illness is associated with poor outcomes. However, reliable predictors for successful outcomes are still unknown. Current literature indicates G-POEM is superior to gastric electric stimulator and surgical pyloroplasty. Endoflip has been used at G-POEM to predict the outcome, but the result is very preliminary. A recent sham study confirms the short-term efficacy of G-POEM. G-POEM is safe and about 50% of patients can be discharged to home on the same day. G-POEM allows for direct biopsy of the gastric muscle, which is the location of the pacemaker cells, the interstitial cells of Cajal; therefore, G-POEM may provide a new path for further research on the pathogenesis of gastroparesis.

Abstract
Third space endoscopy or submucosal endoscopy using a mucosal flap valve allows secure access to the submucosal and deeper layers of the gastrointestinal tract without the risk of a full-thickness perforation. This allows the performance of submucosal tunneling and myotomy for spastic segments of the gastrointestinal tract. Per oral endoscopic myotomy (POEM) has been described for the treatment of achalasia cardia and other spastic esophageal disorders and is widely implemented. Endoscopic pyloromyotomy (G-POEM) has been performed for the treatment of refractory gastroparesis. Z-POEM for Zenker's diverticulum, D-POEM for epiphrenic diverticulum, and per-rectal endoscopic myotomy for treatment of Hirschsprung's disease are described..

Abstract
BACKGROUND AND AIMS G-POEM is an emerging method for treatment of severe gastroparesis. Safe mucosal closure is necessary to avoid adverse events. The aim of this study was to compare the efficacy of two closure methods: clips and endoscopic suturing (ES) after G-POEM. METHODS We performed a single center, prospective study. The closure method was assigned at the discretion of an endoscopist prior to the procedure. The main outcome was the proportion of subjects with successful closure. Unsuccessful closure was defined as a need for a rescue method, or a need for an additional intervention or incomplete closure-related adverse events. Secondary outcomes were the easiness of closure (VAS score 1 = very difficult, 10 = easy), closure time, and cost. RESULTS A total of 40 patients [21 female; mean age, range 47.5; (20-74)] were included; 20 received ES and 20 clips [mean number of clips 6; range (4-19)]. All 20 patients with ES (100%, 95% CI 84-100%) and 18 patients with clips (89%, 95% CI 70-97%) had successful closure (p = 0.49). One patient needed a rescue method (KING closure) and the other patient an additional clipping on POD1. Closure with clips was quicker [mean time 9.8 (range 4-20) min vs. 14.1 (5-21) min; p = 0.007] and cheaper [mean cost 807 USD (± 402) vs. 2353 USD (± 145); p < 0.001]. Endoscopist assessed the easiness of ES and clips as comparable [mean VAS, range 7.5 (3-10) (ES) vs. 6.9 (3-10) (clips); p = 0.3]. CONCLUSIONS Both ES and clips are effective methods for mucosal closure in patients undergoing G-POEM. However, centres using clips should have a rescue closure method available as clips may fail in some patients. Closure with ES is more costly than with clips.

Evaluation of the safety profile of endoscopic pyloromyotomy by G-POEM: a French multicenter study. Therap Adv Gastroenterol 2022; 15:17562848221122472. [PMID: 36213725 PMCID: PMC9536103 DOI: 10.1177/17562848221122472] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 08/02/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Gastric per oral endoscopic esophageal myotomy (G-POEM) is a promising procedure to treat refractory gastroparesis. The safety profile of G-POEM is an important topic because gastroparesis is a functional pathology, with a procedure whose effectiveness is between 50 and 65% depending on the studies. OBJECTIVES We present this retrospective multicenter study, with the aim of establishing a safety profile, focusing on serious adverse events (AEs). DESIGN This was a multicenter observational cohort study conducted in five French expert centers. METHODS All patients who underwent G-POEM for refractory gastroparesis between 2015 and 2021 were included for analysis. AEs were classified into per endoscopic, early postoperative, and late postoperative, up to 1 month. Their severity was assessed using Dindo-Clavien and American Society for Gastrointestinal Endoscopy classification. The primary objective was to evaluate the rate of G-POEM severe AEs. Secondary objectives were to document other postoperative AEs, and to identify predictive factors. RESULTS In all, 217 patients were included: 81 men and 136 women, mean age 52 ± 17 years. The average procedural time was 44 ± 14 min (12-78). The average hospital stay was 3.7 ± 2.3 days. The AEs rate classified as Clavien-Dindo ⩾3 was 0.4% (one delayed bleeding requiring blood transfusion and endoscopic management). There were no deaths or patients admitted to intensive care unit. The rates of mucosotomy and capnoperitoneum were 3.7 and 1.8%, respectively, without clinical consequences. Most patients (81.5%) did not experience any AE. Three cases of dumping syndrome occurred, quickly managed by dietary measures. CONCLUSION Our study confirms the safety of G-POEM with less than 0.5% of serious AEs, medically managed. This outcome makes this a procedure to have a good benefit-risk ratio.

Abstract
Gastroparesis is characterized by symptoms suggesting retention of food in the stomach with objective evidence of delayed gastric emptying in the absence of mechanical obstruction in the gastric outflow. This condition is increasingly encountered in clinical practice. These guidelines summarize perspectives on the risk factors, diagnosis, and management of gastroparesis in adults (including dietary, pharmacological, device, and interventions directed at the pylorus), and they represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation process. When the evidence was not appropriate for Grading of Recommendations, Assessment, Development, and Evaluation, we used expert consensus to develop key concept statements. These guidelines should be considered as preferred but are not the only approaches to these conditions.

Abstract
Background: Gastroparesis is a debilitating medical condition with limited treatment options. Gastric per-oral pyloromyotomy (G-POEM) has emerged as a promising treatment option with remarkable short-term clinical success shown in multiple studies. While the post-procedure protocol is not standardized across many centers, the majority of the centers observes these patients in the hospital after the procedure for monitoring. In this single-center prospective study, we evaluated the safety and feasibility of same day discharge after the G-POEM procedure. Methods: All the patients with refractory gastroparesis undergoing G-POEM from October 2019 to March 2020 were enrolled. A total of 25 patients were enrolled in the procedure. Based on the pre-defined criteria, patients were either discharged on the same day after the procedure or admitted to the hospital for further observation. The patient and procedure-related data were extracted from the chart review. Univariate analysis was performed (chi-squared test) on categorical variables after organizing categorical variables as numeric counts or percentages. The student t test was performed on continuous variables after reporting as mean and standard deviation. For analysis with a smaller sample size, Fisher exact and Mann–Whitney tests were used. Results: A total of 25 patients were enrolled. The technical success of G-POEM was 100% and clinical success was 80% (20/25) at 1-month follow-up. Of the 25 patients, 9 patients (36%) were discharged on the same day according to the procedure from the recovery unit. Of the remaining 16 patients who were admitted to the hospital post-procedure, 10 (40%) were admitted due to procedure-related causes while other admissions were either pre-planned or due to social reasons. The average Charlson comorbidity index was lower in the same day discharge group (P < 0.05). The number of patients requiring double myotomy was higher in the same day discharge group (P < 0.05). The overall complication rate of G-POEM in the study cohort was 12% (3/25) with all complications being mild without any severe adverse events. Conclusion: G-POEM is a safe and effective method of treatment for refractory GP with higher clinical success in short-term follow-up. The same day discharge after G-POEM is safe and feasible in >50% of patients with close periprocedural monitoring.

Abstract
Our tripartite narrative review discusses Peroral Endoscopic Myotomy (POEM), gastric POEM (GPOEM) and POEM for Zenker's diverticula (ZPOEM). POEM is the prototypical procedure that launched the novel "3rd space endoscopy" field of advanced endoscopy. It revolutionized achalasia therapy by offering a much less invasive version of the prior gold standard, the laparoscopic Heller myotomy (HM). We review in detail indications, outcomes, technique variations and comparative data between POEM and HM particularly with regard to the hotly debated issue of GERD. We then proceed to discuss two less illustrious but nevertheless important offshoots of the iconic POEM procedure: GPOEM for gastroparesis and ZPOEM for the treatment of hypopharyngeal diverticula. For GPOEM, we discuss the rationale of pylorus-directed therapies, briefly touch on GPOEM technique variations and then focus on the importance of proper patient selection and emerging data in this area. On the third and final part of our review, we discuss ZPOEM and expound on technique variations including our "ultra-short tunnel technique". Our review emphasizes that, despite the superiority of endoscopy over surgery for the treatment of hypopharyngeal diverticula, there is no clear evidence yet of the superiority of the newfangled ZPOEM technique compared to the conventional endoscopic myotomy technique practiced for over two decades prior to the advent of ZPOEM.

Abstract
Simple Summary Flexible endoscopy has an important part in the diagnosis and treatment of postoperative complications after oncologically intended esophagectomy. Endoscopy offers the possibility of effective therapy with minimal invasiveness at the same time, and the use of endoscopic therapy procedures can avoid re-operations. In this review we present the advantages of endoscopic treatment opportunities during the last 20 years regarding patients’ treatment after esophageal cancer resection. According to prevalence and clinical relevance, four relevant postoperative complications were identified and their endoscopic treatment procedures discussed. All endoscopic therapy procedures for anastomotic bleeding, anastomotic insufficiencies, anastomotic stenosis and postoperative delayed gastric emptying are presented, including innovative developments. Abstract Background: Esophageal cancer (EC) is the sixth-leading cause of cancer-related deaths in the world. Esophagectomy is the most effective treatment for patients without invasion of adjacent organs or distant metastasis. Complications and relevant problems may occur in the early post-operative course or in a delayed fashion. Here, innovative endoscopic techniques for the treatment of postsurgical problems were developed during the past 20 years. Methods: Endoscopic treatment strategies for the following postoperative complications are presented: anastomotic bleeding, anastomotic insufficiency, delayed gastric passage and anastomotic stenosis. Based on a literature review covering the last two decades, therapeutic procedures are presented and analyzed. Results: Addressing the four complications mentioned, clipping, stenting, injection therapy, dilatation, and negative pressure therapy are successfully utilized as endoscopic treatment techniques today. Conclusion: Endoscopic treatment plays a major role in both early-postoperative and long-term aftercare. During the past 20 years, essential therapeutic measures have been established. A continuous development of these techniques in the field of endoscopy can be expected.

Abstract
Gastroparesis is a chronic disease of the stomach that causes a delayed gastric emptying, without the presence of a stenosis. For 30 years the authors identified pylorospasm as one of the most important pathophysiological mechanisms determining gastroparesis. Studies with EndoFLIP, a device that assesses pyloric distensibility, increased the knowledge about pylorospasm. Based on this data, several pyloric-targeted therapies were developed to treat refractory gastroparesis: Surgical pyloroplasty and endoscopic approach, such as pyloric injection of botulinum and pyloric stenting. Notwithstanding, the success of most of these techniques is still not complete. In 2013, the first human gastric per-oral endoscopic myotomy (GPOEM) was performed. It was inspired by the POEM technique, with a similar dissection method, that allows pyloromyotomy. Therapeutical results of GPOEM are similar to surgical approach in term of clinical success, adverse events and post-surgical pain. In the last 8 years GPOEM has gained the attention of the scientific community, as a minimally invasive technique with high rate of clinical success, quickly prevailing as a promising therapy for gastroparesis. Not surprisingly, in referral centers, its technical success rate is 100%. One of the main goals of recent studies is to identify those patients that will respond better to the therapies targeted on pylorus and to choose the better approach for each patient.

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
Gastroparesis is characterized by symptoms suggestive of, and objective evidence of, delayed gastric emptying in the absence of mechanical obstruction. This review addresses the normal emptying of solids and liquids from the stomach and details the myogenic and neuromuscular control mechanisms, including the specialized function of the pyloric sphincter, that result in normal emptying, based predominantly on animal research. A clear understanding of fundamental mechanisms is necessary to comprehend derangements leading to gastroparesis, and additional research on human gastric muscles is needed. The section on pathophysiology of gastroparesis considers neuromuscular diseases that affect nonsphincteric gastric muscle, disorders of the extrinsic neural control, and pyloric dysfunction that lead to gastroparesis. The potential cellular basis for gastroparesis is attributed to the effects of oxidative stress and inflammation, with increased pro-inflammatory and decreased resident macrophages, as observed in full-thickness biopsies from patients with gastroparesis. Predominant diagnostic tests involving measurements of gastric emptying, the use of a functional luminal imaging probe, and high-resolution antral duodenal manometry in characterizing the abnormal motor functions at the gastroduodenal junction are discussed. Management is based on supporting nutrition; dietary interventions, including the physical reduction in particle size of solid foods; pharmacological agents, including prokinetics and anti-emetics; and interventions such as gastric electrical stimulation and pyloromyotomy. These are discussed briefly, and comment is added on the potential for individualized treatments in the future, based on optimal gastric emptying measurement and objective documentation of the underlying pathophysiology causing the gastroparesis.

Abstract
GOAL A comprehensive review of treatments for nausea and vomiting (N/V). BACKGROUND N/V are common symptoms encountered in medicine. While most cases of acute N/V related to a specific cause can be straightforward to manage, other cases of acute N/V such as chemotherapy-induced N/V and especially chronic unexplained N/V can be difficult to control, leading to a significant decline in the patient's quality of life and increased cost of medical care from repeated hospitalizations. STUDY Traditional management has relied on pharmacotherapy which may be inadequate in a certain proportion of these patients. Many of the medications used in the management of N/V have significant side effect profiles making the need for new and improved interventions of great importance. RESULTS This review covers a broad review of the pathophysiology of N/V, pharmacotherapy, including safety concerns and controversies with established pharmaceuticals, newer immunotherapies, bioelectrical neuromodulation (including gastric electrical stimulation), behavioral and surgical therapies, and complementary medicine. CONCLUSION On the basis of emerging understandings of the pathophysiology of N/V, improved therapies are becoming available.

Long-term Outcome of Gastric Per-Oral Endoscopic Pyloromyotomy in Treatment of Gastroparesis. Clin Gastroenterol Hepatol 2021; 19:816-824. [PMID: 32450364 DOI: 10.1016/j.cgh.2020.05.039] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 05/15/2020] [Accepted: 05/18/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Gastric per oral endoscopic pyloromyotomy (GPOEM) is a promising treatment for gastroparesis. There are few data on the long-term outcomes of this procedure. We investigated long-term outcomes of GPOEM treatment of patients with refractory gastroparesis. METHODS We conducted a retrospective case-series study of all patients who underwent GPOEM for refractory gastroparesis at a single center (n = 97), from June 2015 through March 2019; 90 patients had more than 3 months follow-up data and were included in our final analysis. We collected data on gastroparesis cardinal symptom index (GCSI) scores (measurements of postprandial fullness or early satiety, nausea and vomiting, and bloating) and SF-36 questionnaire scores (measures quality of life). The primary outcome was clinical response to GPOEM, defined as a decrease of at least 1 point in the average total GCSI score with more than a 25% decrease in at least 2 subscales of cardinal symptoms. Recurrence was defined as a return to baseline GCSI or GCSI scores of 3 or more for at least 2 months after an initial complete response. The secondary outcome was the factors that predict GPOEM failure (no response or gastroparesis recurrence within 6 months). RESULTS At initial follow-up (3 to 6 months after GPOEM), 73 patients (81.1%) had a clinical response and significant increases in SF-36 questionnaire scores (indicating increased quality of life) whereas 17 patients (18.9%) had no response. Six months after GPOEM, 7.1% had recurrence. At 12 months, 8.3% of patients remaining in the study had recurrence. At 24 months, 4.8% of patients remaining in the study had a recurrence. At 36 months, 14.3% of patients remaining in the study had recurrence. For patients who experienced an initial clinical response, the rate of loss of that response per year was 12.9%. In the univariate and multivariate regression analysis, a longer duration of gastroparesis reduced the odds of response to GPOEM (odds ratio [OR], 0.092; 95% CI, 1.04-1.3; P = .001). On multivariate logistic regression, patients with high BMIs had increased odds of GPOEM failure (OR, 1.097; 95% CI, 1.022-1.176; P = .010) and patients receiving psychiatric medications had a higher risk of GPOEM failure (OR, 1.33; 95% CI, 0.110-1.008; P = .052). CONCLUSIONS In retrospective analysis of 90 patients who underwent GPOEM for refractory gastroparesis, 81.1% had a clinical response at initial follow-up of their procedure. 1 year after GPOEM, 69.1% of all patients had a clinical response and 85.2% of initial responders maintained a clinical response. Patients maintained a clinical response and improved quality of life for as long as 3 years after the procedure. High BMI and long duration gastroparesis were associated with failure of GPOEM.

Gastric peroral endoscopic pyloromyotomy for decompensated gastroparesis: comprehensive motility analysis in relation to treatment outcomes. Endosc Int Open 2021; 9:E137-E144. [PMID: 33532550 PMCID: PMC7834704 DOI: 10.1055/a-1311-0859] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Accepted: 10/05/2020] [Indexed: 12/26/2022] Open
Abstract
Background and study aims There are no reliable data to predict which patients with gastroparesis (GP) would benefit the most from gastric peroral endoscopic pyloromyotomy (G-POEM). The aim of the present study was to assess whether antro-duodenal motility patterns and pyloric distensibility can predict the outcome of G-POEM in patients with decompensated GP. Patients and methods In an open-label study, patients with GP and refractory symptoms were eligible for treatment with G-POEM if treatment attempts according to a standardized stepwise protocol had failed. Baseline assessment included Gastroparesis Cardinal Symptom Index (GCSI), C13-octanoic gastric emptying breath test and high-resolution antro-duodenal manometry. Pyloric distensibility using EndoFlip measurements was assessed at baseline and 3 months after the procedure. Explorative analyses were performed on potential predictors of response using logistic regression analyses. Results Twenty-four patients with decompensated GP underwent G-POEM. At baseline, 78.3 % and 61.9 % of patients showed antral hypomotility and neuropathic motor patterns, respectively. The technical success rate was 100 % (24/24). Mean GCSI improved significantly at 3, 6, and 12 months after G-POEM ( P = 0.01). Median distensibility index (DI) improved significantly as compared with baseline (7.5 [6.9;11.7] vs. 5.3[3.1;8.1], P = 0.004). A significant correlation was found between clinical response at 6 months and pyloric DI improvement ( P = 0.003). No potential predictors of clinical response after G-POEM could be identified in an explorative analysis. Conclusions G-POEM improved pyloric distensibility patterns in patients with decompensated GP. Clinical response at 6 months after G-POEM was associated with pyloric distensibility improvement. However, no potential predictors of response could be identified from either antro-duodenal motility patterns or pyloric distensibility.

Abstract
Background: Gastric per oral endoscopic myotomy (GPOEM) was developed as a therapeutic option for gastroparesis after the pylorus was identified as a key target for gastroparesis management. This study includes a systematic literature review of studies in which GPOEM was utilized as therapy for gastroparesis. Methods: A literature search was conducted in three databases (MEDLINE, Scopus and Embase) of articles that included the keywords “GPOEM”, “Gastric per oral endoscopy myotomy” or “per oral pyloromyotomy” and “Gastroparesis” in the abstract or title. The search covered articles published until 29 February 2020. Results: A total of 139 articles were identified. Only 15 articles met the final inclusion criteria and were retrieved for qualitative data synthesis. Conclusion: GPOEM for gastroparesis is shown to have a high success rate among the studies but data interpretations are limited because of small sample sizes and short follow-up. Subjective and objective data prior to and post-GPOEM will be mandatory to establish credibility. The procedure is technically feasible and safe based on the limited studies available.

Abstract
BACKGROUND AND AIMS Gastroparesis is a symptomatic chronic disorder of the stomach characterized by delayed gastric emptying in the absence of mechanical obstruction. Several endoscopic treatment modalities have been described that aim to improve gastric emptying and/or symptoms associated with gastroparesis refractory to dietary and pharmacologic management. METHODS In this report we review devices and techniques for endoscopic treatment of gastroparesis, the evidence regarding their efficacy and safety, and the financial considerations for their use. RESULTS Endoscopic modalities for treatment of gastroparesis can be broadly categorized into pyloric, nonpyloric, and nutritional therapies. Pyloric therapies such as botulinum toxin injection, stent placement, pyloroplasty, and pyloromyotomy specifically focus on pylorospasm as a therapeutic target. These interventions aim to reduce the pressure gradient across the pyloric sphincter, with a resultant improvement in gastric emptying. Nonpyloric therapies, such as venting gastrostomy and gastric electrical stimulation, are intended to improve symptoms. Nutritional therapies, such as feeding tube placement, aim to provide nutritional support. CONCLUSIONS Several endoscopic interventions have shown utility in improving the quality of life and symptoms of select patients with refractory gastroparesis. Methods to identify which patients are best suited for a specific treatment are not well established. Endoscopic pyloromyotomy is a relatively recent development that may prove to be the preferred pyloric-directed intervention, although additional and longer-term outcomes are needed.

Short-term outcomes of double versus single pyloromyotomy at peroral endoscopic pyloromyotomy in the treatment of gastroparesis (with video). Gastrointest Endosc 2020; 92:603-609. [PMID: 31958460 DOI: 10.1016/j.gie.2020.01.016] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Accepted: 01/08/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS The prevalence of gastroparesis (Gp), a chronic debilitating disorder, and resulting hospitalizations are increasing. Gastric peroral endoscopic pyloromyotomy (POP or GPOEM) is a novel technique in the treatment of refractory Gp. Despite the initial promising results of GPOEM, one-third of patients do not exhibit any clinical response. Furthermore, loss of clinical response was reported in several studies. No response or loss of response after GPOEM may be related to inadequate myotomy. The aim of our study is to examine whether double pyloromyotomy at GPOEM is superior to single pyloromyotomy. METHOD A retrospective case-controlled study of patients who underwent GPOEM for refractory Gp at our tertiary care institution between June 2015 and March 2018 was performed. Because the follow-up time for the single myotomy group was much longer than that of the double myotomy group, we matched the length of follow-up for the single myotomy group to that of the double myotomy group. The outcomes were measured by the changes in the Gastroparesis Cardinal Symptom Index (GCSI) before and 3 to 6 months after the procedure. Adverse events and other procedural and clinical parameters were also compared. RESULTS Ninety patients underwent GPOEM (55 single and 35 double pyloromyotomy). The mean age was 47 ± 14 years, and the mean duration of symptoms was 5.3 ± 4.4 years. The average GCSI score was 3.8 before the GPOEM, and the average GCSI score 6 months after procedure was 1.8. Thirty-seven of 55 (67%) patients who underwent single pyloromyotomy achieved clinical response compared with 30 of 35 (86%) patients who underwent double pyloromyotomy. There were no significant differences for procedure time, postoperative pain, or length of hospital stay between the 2 groups. There was no difference in adverse events in the 2 pyloromyotomy groups. CONCLUSION Double pyloromyotomy is a safe and feasible technique during GPOEM. Clinical success was higher in patients undergoing double pyloromyotomy compared with single pyloromyotomy in this nonrandomized, short-term follow-up study. Long-term studies are needed to further confirm our results.

Abstract
Background and aim Gastric peroral endoscopic pyloromyotomy (G-POEM) is a new therapeutic option for refractory gastroparesis (GP). A systematic review and meta-analysis was conducted to assess the effectiveness of G-POEM in refractory GP. For the quality of evidence, we used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Methods We performed a literature search using MEDLINE, Embase, Cochrane library, LILACS and the Science citation index for studies related to G-POEM from the inception of its technique through January 2019. We selected studies that analyzed the gastroparesis cardinal symptom index (GCSI) and 4-hour solid-phase gastric emptying scintigraphy (GES) before and after the procedure to verify the efficacy of G-POEM, the main outcome measured. An analysis was performed using RevMan 5.3. Results Ten studies comprising 281 patients were included in this systematic review. The pooled mean difference in GCSI following the procedure was 1.76 (95 % CI: [1.43, 2.08], I 2 = 72 %). We also performed GCSI subgroup analysis by follow-up duration that showed a pooled mean difference of 1.84 (95 % CI: [1.57, 2.12], I 2 = 71 %). The pooled mean difference in GES after the procedure was 26.28 (95 % CI: [19.74, 32.83], I 2 = 87 %), corresponding to a significant drop in percentage values of the gastric retention 4-hour scintigraphy. Conclusion This meta-analysis demonstrates that G-POEM is effective and shows promising outcomes in the clinical response and gastric emptying scintigraphy for gastroparesis. Therefore, it should be considered in the management of refractory gastroparesis.

Abstract
BACKGROUND AND AIMS Gastroparesis (GP) is a chronic debilitating condition. Prior pyloric-targeted procedures are either invasive or have questionable efficacy. Gastric peroral pyloromyotomy (G-POEM) has been proposed as a minimally invasive approach. We performed a pooled analysis to evaluate the efficacy and safety of G-POEM for GP. METHODS Electronic databases (Medline, Scopus, EMBASE) were searched up to January 2019. Studies including patients who underwent G-POEM for GP were eligible. Procedural, clinical, and safety outcomes were assessed by pooling data with a random- or fixed-effect model according to the degree of heterogeneity to obtain a proportion with a 95% confidence interval. RESULTS Ten studies were eligible for inclusion (292 patients), and 2 of the 10 studies were prospective. Seven studies were performed in the United States, 2 in France, and 1 in China. Endoscopic pyloromyotomy was feasible in all patients. Significant symptomatic improvement was achieved after 83.9% of procedures (mean follow-up, 7.8 ± 5.5 months). When comparing the mean values of pre- and postprocedural scintigraphic evolution, there was a significant decrease of the residual percentage at 2 and 4 hours. The overall adverse events rate was 6.8%. CONCLUSIONS G-POEM appears to be a promising approach for GP in terms of safety and efficacy outcomes in the short term.

Abstract
AIM to evaluate the efficacy and safety of gastric per-oral endoscopic myotomy (G-POEM) for the treatment of refractory gastroparesis. METHODS PubMed, Embase and Cochrane databases were searched and used for study inclusion. Clinical studies since January 2013 to October 2019 were identified as suitable for inclusion. Conference papers, review articles, case reports, animal studies, letters, studies with repetitive data, studies that did not mention the Gastroparesis Cardinal Symptom Index (GCSI) score/gastric emptying scintigraphy (GES) hours or were not indicated in the standard form were excluded. GCSI score, GCSI reduction, gastric emptying scintigraphy at four hours (GES-4h) and GES time (GET) reduction were considered as major indexes and the meta-analysis was achieved using Review Manager 5.3. Research bias was measured according to Cochrane handbook. RESULTS nine studies were included with a total of 235 patients that underwent G-POEM, and the technical success rate was 100%. After G-POEM, patients reported changes in GCSI score (6/9 studies, mean difference 1.41 [CI: 0.93, 1.88], p < 0.0001), GCSI reduction (8/9 studies, odds ratio 3.00 [CI: 2.24, 4.03], p < 0.0001), GES-4h (8/9 studies, mean difference 23.78 [CI: 19.88, 27.68], p < 0.00001) and GET reduction (6/9 studies, odds ratio 3.50 [CI: 2.12, 5.78], p < 0.00001). The intra-procedure complication rate was 5.1% (12/235), including capnoperitoneum (seven cases) and accidental mucotomy (five cases). The post-procedure complication rate was 6.8% (16/235), including abdominal pain (three cases), bleeding (three cases), ulcer (one case), difficulty swallowing (one case) and others (eight cases). Both per- and post-procedure complications were easily managed by conservative or endoscopic treatments. CONCLUSION the results show that gastroparesis patients can benefit from G-POEM, the success rate was impressive and the complication rate was relatively low. However, caution is necessary when interpreting the results, primarily due to the limitations of uncontrolled studies. Randomized control studies are still needed for further evaluations.

Abstract
The field of third space endoscopy (TSE), also called submucosal endoscopy using a mucosal flap valve, allows secure access to the submucosal and deeper layers of the gastrointestinal tract without the risk of a full-thickness perforation. Since the first description of per-oral endoscopic myotomy (POEM) for the treatment of achalasia cardia 10 years ago, this field has expanded rapidly. Several new procedures, submucosal tunneling endoscopic resection, gastric-POEM, Zenker POEM, per-rectal endoscopic myotomy, diverticular POEM, and recanalization for complete esophageal obstruction (per-oral endoscopic tunneling for restoration of the esophagus), have been performed. All TSE procedures employ a similar technique-after a mucosal incision, a submucosal tunnel is created, a myotomy is performed, or a subepithelial tumor is resected distal to the site of mucosal incision, after which the mucosal incision is closed. Potential indications for TSE include resection of subepithelial tumors in the esophagus, gastroesophageal junction, or stomach; refractory gastroparesis; Zenker diverticulum; Hirschsprung disease or other forms of megacolon; and recanalization for complete esophageal obstruction. Data are currently available for POEM, submucosal tunneling endoscopic resection, and gastric-POEM, although mainly in the form of retrospective studies, and randomized trials and long-term follow-up data are limited. Submucosal endoscopy has an excellent safety profile with very few intraoperative adverse events, the majority being related to insufflation, although bleeding, perforation, and sepsis have been reported. TSE procedures require special training and have demonstrated a learning curve.

Abstract
PURPOSE OF REVIEW The main scope of this review article is to introduce readers to the innovative field of third-space endoscopy and offer a closer look at its history, milestones, and procedure spectrum while discussing ongoing and future challenges arising from its increasing adoption worldwide. RECENT FINDINGS Over the past few years, third-space endoscopy has been utilized in various diagnostic and interventional procedures performed throughout the gastrointestinal tract: obliteration of Zenker's diverticulum, myotomy for achalasia, gastroparesis or Hirschsprung's disease, biopsy or removal of subepithelial tumors, stricture management, post-per-oral endoscopic myotomy endoscopic fundoplication, and mediastino-, thoraco-, and peritoneoscopy. Third-space endoscopic interventions have revolutionized the management of esophageal motility disorders, gastroparesis, and gastrointestinal tract subepithelial tumors. Despite the high efficacy and safety of such interventions, some common (e.g., the high level of necessary endoscopic skill) and unique for each procedure (e.g., post-procedure gastroesophageal reflux or poor outcomes in patient subgroups) challenges still remain. Through a dedicated endoscopic training, a rigorous pre-procedure patient evaluation and selection, and the application of modified or new techniques, challenges can be overcome thus establishing existing procedures and paving the way for additional breakthroughs in the field of third-space endoscopy.

Chang KJ. Endoscopic foregut surgery and interventions: The future is now. The state-of-the-art and my personal journey. World J Gastroenterol 2019; 25:1-41. [PMID: 30643356 PMCID: PMC6328959 DOI: 10.3748/wjg.v25.i1.1] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/13/2018] [Accepted: 12/14/2018] [Indexed: 02/06/2023] Open
Abstract
In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic, the content will progress as follows: "lessons learned", "technical considerations" and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years. Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver, pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease (GERD), achalasia, esophageal diverticula, Barrett's esophagus (BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors. For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy (POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique (Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection (ESD) which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies (radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy. Importantly, in regard to early gastric cancer and submucosal tumors (SMTs) of the stomach, ESD and full thickness resection (FTR) can excise these lesions en-bloc and endoscopic suturing is now used to close large defects and perforations. For treatment of patients with malignant gastric outlet obstruction (GOO), endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty (ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound (EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.
