Seven-Year Experience of Intramural Surgery in the Middle East: A Safety and Feasibility Analysis. J Clin Med 2024; 13:3989. [PMID: 38999553 PMCID: PMC11242680 DOI: 10.3390/jcm13133989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Revised: 06/26/2024] [Accepted: 07/04/2024] [Indexed: 07/14/2024] Open
Abstract
Background: Intramural surgery techniques, particularly esophageal peroral endoscopic myotomy (E-POEM), gastric peroral endoscopic myotomy (G-POEM), and peroral endoscopic myotomy for Zenker's (Z-POEM), have emerged as forefront minimally invasive endoscopic procedures. While several studies have reported on the outcomes in North America and Asia, evidence in the Middle East and North Africa remains limited. This study aims to evaluate the feasibility and safety of intramural surgery techniques within this region. Methods: This retrospective cohort study was conducted with approval from the institutional review board. All patients who underwent esophageal peroral endoscopic myotomy, gastric peroral endoscopic myotomy, and peroral endoscopic myotomy for Zenker's from January 2016 to August 2023 were included. Results: In total, 119 patients underwent intramural surgery procedures during this period. The esophageal peroral endoscopic myotomy group had 81 (68%) patients, the gastric peroral endoscopic myotomy had 34 (28.6%) patients, and the peroral endoscopic myotomy for Zenker's had 4 (3.4%) patients. The full cohort was 48.7% female, with a mean overall age of 40.5 years. The mean overall body mass index was 27.5 kg/m2. The chief complaint was dysphagia (n = 80, 67.2%). All cases were successfully completed endoscopically. During the first 30 days, the most common complications were nausea/vomiting requiring admission (n = 4, 4.76%) and pneumomediastinum (n = 2, 2.38%). At a follow-up of 19 months, there were four mortalities; the causes of death were cardiac arrest (three cases) and end-stage prostate cancer (one case). Conclusions: Intramural surgery techniques are safe and technically feasible with low complication rates. Our study suggests that clinical success in the Middle East and Northern Africa population is comparable to larger international series.

Abstract
PURPOSE OF REVIEW Third space endoscopy (TSE) offers diverse treatment options for a variety of conditions of the gastrointestinal tract and motility disorders. Accuracy and precise dissection have helped treat complex conventional surgeries with TSE. Despite over a decade of its presence, difficult situations are routinely encountered. RECENT FINDINGS The first challenging situation is decision-making (before the procedure), the second is tackling procedure-induced pulmonary / insufflation-related adverse events and intra-operative complications (during the procedure), and the third is post-operative complications and morbidity (post-procedure). The performance of TSE procedures is not without risk. Patients should receive enough time to weigh their options, considering that attitudes toward risk impact decision-making. Continuous basic patient monitoring and the micro-movements of endoscopic and electrosurgical equipment is crucial to avoid accidental injury. Anaesthetists should be mindful of anticipated complications and closely monitor, diagnose, and treat them. Demanding situations need careful consideration, problem-solving, or persistence to overcome challenges. This brief review provides inputs on preventing and tackling difficult situations in TSE.

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
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
BACKGROUND : Patients with gastroparesis who have undergone prior intrapyloric botulinum toxin injection (BTI) may seek an opinion regarding peroral pyloromyotomy (POP). There are only two small reports assessing the role of BTI as a predictor for successful treatment with POP. METHODS We performed a retrospective cohort study to assess whether symptomatic improvement after BTI predicts a response to POP. We included 119 patients who had undergone both BTI and POP at Cleveland Clinic Ohio or Cleveland Clinic Florida from January 2016 to September 2019. RESULTS 65.5 % of patients had symptomatic improvement after BTI. Gastroparesis Cardinal Symptom Index (GCSI) scores were available for 74 patients, with 64 % achieving a response to POP, defined as a decrease in mean GCSI ≥ 1. In multivariable analysis, response to BTI (odds ratio [OR] 7.7 [95 %CI 2.2-26.1]) and higher pre-POP GCSI score (OR 2.3 [95 %CI 1.2-4.6]) were independent predictors of response to POP. CONCLUSIONS Clinical improvement after BTI is a predictor of response to POP in patients with gastroparesis. This information may aid in improving patient selection for POP.

Abstract
BACKGROUND The pylorus plays a key role in the control of gastric content outflow. Impairment of pyloric physiology has been observed in gastroparesis, particularly when associated with diabetes mellitus or opioid intake or after antireflux surgery. New tools have been developed to identify pyloric dysfunction in routine care, including functional luminal impedance planimetry (FLIP). As such, a new therapeutic strategy targeting the pylorus, namely endoscopic pyloromyotomy (G-POEM), has received increasing attention and emerged as a promising treatment for gastroparesis. PURPOSE The present review details the involvement of the pyloric pathophysiology in gastroparesis, as well as clinical results of G-POEM according to the current literature.

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
Submucosal endoscopy (third-space endoscopy) can be defined as an endoscopic procedure performed in the submucosal space. This procedure is novel and has been utilized for delivery to the submucosal space in a variety of gastrointestinal diseases, such as a tumor, achalasia, gastroparesis, and subepithelial tumors. The main submucosal endoscopy includes peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, and endoscopic submucosal tunnel dissection. Submucosal endoscopy has been used as a viable alternative to surgical techniques because it is minimally invasive in the treatment and diagnosis of gastrointestinal diseases and disorders. However, there is limited evidence to prove this. This article reviews the current applications and evidence regarding submucosal endoscopy while exploring the possible future clinical applications in this field. As our understanding of these procedures improves, the future of submucosal endoscopy could be promising in the fields of diagnostic and therapeutic endoscopy.

Abstract
Gastroparesis, once regarded as a rare disease, is difficult to diagnose and challenging to treat; there were many breakthrough advances in the 2010s, shifting the paradigm of the understanding of this complex entity and its management. Similar to diabetes, its increasing prevalence reflects increased accessibility to diagnostic modalities and suggests that gastroparesis was underacknowledged in the past. Major developments in the three main aspects of the disease include the discovery of smooth muscle cells, interstitial cells of Cajal, PDGFRα+ cells syncytium, rather than interstitial cells of Cajal alone, as the main gastric pacemaker unit; the development of validated point-of-care diagnostic modalities such as a wireless motility capsule, the carbon 13-labeled breath test, and impedance planimetry; and the introduction of novel minimally invasive therapeutic options such as newer pharmacologic agents and gastric peroral endoscopic pyloromyotomy. All aspects of these advances will be discussed further in this review.

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
Third space endoscopy (TSE), a type of natural orifice transluminal endoscopic surgery, was first introduced a decade ago, and since then, has revolutionized the field of therapeutic endoscopy. TSE involves tunneling into the submucosal space between the intestinal mucosa and the muscularis propria. By accessing this "third space," endoscopists can perform minimally invasive myotomies, resections, and dissections while maintaining the mucosa and preventing full-thickness perforation. TSE procedures can be used to treat motility disorders as well as neoplasms throughout the gastrointestinal tract, which were traditionally conditions that would require open or laparoscopic surgery. The main TSE procedures include peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, endoscopic submucosal tunnel dissection, peroral endoscopic tunneling for restoration of the esophagus, and per-rectal endoscopic myotomy. Some of those procedures have now been accepted as viable alternative to surgical techniques due to their limited invasiveness, safety and cost. This review will explore the different techniques recently added to our arsenal while describing their potential efficacy and limitations.

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

Abstract
OBJECTIVE Although gastric per-oral endoscopic myotomy (G-POEM) is considered a promising technique for the management of refractory gastroparesis, high-quality evidence is limited. We prospectively investigated the efficacy and safety of G-POEM in unselected patients with refractory gastroparesis. DESIGN In five tertiary centres, patients with symptomatic gastroparesis refractory to standard medical therapy and confirmed by impaired gastric emptying were included. The primary endpoint was clinical success, defined as at least one score decrease in Gastroparesis Cardinal Symptom Index (GCSI) with ≥25% decrease in two subscales, at 12 months. GCSI Score and subscales, adverse events (AEs) and 36-Item Short Form questionnaire of quality of life were evaluated at baseline and 1, 3, 6 and 12 months after G-POEM. Gastric emptying study was performed before and 3 months after the procedure. RESULTS Of 80 enrolled patients, 75 patients (94%) completed 12-month follow-up. Clinical success at 12 months was 56% (95% CI, 44.8 to 66.7). GCSI Score (including subscales) improved moderately after G-POEM (p<0.05). In a regression model, a baseline GCSI Score >2.6 (OR=3.23, p=0.04) and baseline gastric retention >20% at 4 hours (OR=3.65, p=0.03) were independent predictors of clinical success at 12 months, as was early response to G-POEM at 1 month after therapy (OR 8.75, p<0.001). Mild procedure-related AEs occurred in 5 (6%) patients. CONCLUSION G-POEM is a safe procedure, but showed only modest overall effectiveness in the treatment of refractory gastroparesis. Further studies are required to identify the best candidates for G-POEM; unselective use of this procedure should be discouraged. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry NCT02732821.

Abstract
Autonomic neuropathy in patients with diabetes mellitus, and especially complications related to gastrointestinal neuropathy, are often overlooked in the clinic. Diabetic gastroenteropathy affects every segment of the gastrointestinal tract and generates symptoms that may include nausea, early satiety, vomiting, abdominal pain, constipation, and diarrhea. Severe cases can be complicated by weight loss, dehydration, and electrolyte disturbances. The pathophysiology is complex, the diagnostics and treatment options are multidisciplinary, and there is generally a lack of evidence for the treatment options. The aims for this review are first to summarize the pathophysiology and describe possible and expected symptoms and complications.Further, we will try to supply the clinician with a straightforward tool for diagnostics, and then, we shall summarize established treatment options, including diet recommendations, pharmacological and non-pharmacological options. Finally, we will explore the multiple possibilities of novel treatment, looking at medications related to the pathophysiology of neuropathy, other manifestations of autonomic neuropathies, and symptomatic treatment for other gastrointestinal disorders, also including new knowledge of endosurgical and neuromodulatory treatment. The overall goal is to increase awareness and knowledge on this frequent diabetic complication and to provide better tools for diagnosis and treatment. Ultimately, we hope to encourage further research in this field, as there are clear shortcomings in terms of biomarkers, pathophysiology, as well as treatment possibilities. In conclusion, diagnosis and management of diabetic gastroenteropathy are challenging and often require multidisciplinary teams and multimodal therapies. Treatment options are sparse, but new pharmacological, endoscopic, and neuromodulatory techniques have shown promising results in initial studies.

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
BACKGROUND AND AIM Gastroparesis is a potentially debilitating gastric motility disorder with limited treatment options. Highest efficacy treatments include gastric per-oral endoscopic myotomy (GPOEM) and surgical pyloromyotomy. This study compares the efficacy and safety of GPOEM versus laparoscopic pyloromyotomy for refractory gastroparesis. METHODS Patients who underwent GPOEM or laparoscopic pyloromyotomy for refractory gastroparesis from four centers across the USA and Latin America were included in a dedicated registry. Data collected included patient demographics, imaging, laboratory values, clinical success, gastroparesis cardinal symptom index, procedure time, pre-op and post-op gastric emptying times, adverse events, and hospital length of stay. RESULTS A total of 102 patients were included (mean age 47; 32.4% male): GPOEM n = 39, surgical pyloromyotomy n = 63.Technical success was 100% in both groups. Clinical success was 92.3% in the GPOEM group and 82.5% in the surgery group (P = 0.164). The GPOEM group had a significantly higher post-op GSCI score reduction by 1.3 units (P < 0.00001), post-op retention reduction at 2 h by 18% (P < 0.00001), post-op retention reduction at 4 h by 25% (P < 0.00001) and a lower procedure time by 20 min (P < 0.00001) as compared with surgery. GPOEM also had a lower hospital length of stay by 2.8 days (P < 0.00001). Adverse events were significantly fewer in the GPOEM group (13%) compared with surgery group (33.3%; P = 0.021). Mean blood loss in the GPOEM group was only 3.6 mL compared with 866 mL in the surgery group. CONCLUSIONS The GPOEM may be a less invasive, safer, and more efficacious procedural treatment for refractory gastroparesis as compared with surgical pyloromyotomy.

Abstract
Introduction: Esophagus dysmotility is a crucial risk factor of gastroesophageal reflux disease (GERD), which is one of the most common diseases in digestive medicine globally. This review emphasizes the mechanisms of esophagus dysmotility in diabetes and summarizes more targeted treatments for these patients to avoid the overuse of proton pump inhibitors (PPIs).Areas covered: Diabetes mellitus (DM) is a clear factor that must not be neglected in the development of GERD. Previous studies have preliminarily researched the esophagus deterioration in diabetes. However, the multi-faceted mechanisms of esophagus dysmotility in diabetes need more studies. Besides, targeted treatments for these patients rather than conventional PPIs are urgently needed.Expert opinion: The treatments for GERD patients with diabetes should be further explored. Pharmacological approaches such as prokinetic agents, psychotherapy can be adopted. Meanwhile, it's feasible to explore non-drug treatments. For example, Electroacupuncture (EA) at Zusanli (ST-36) may be effective to protect the networks of intestinal cells of Cajal (ICCs) in diabetes. More effective approaches should be explored to achieve individualized treatment for these patients.

Abstract
The field of endoscopic esophageal surgery is based on the concept of natural orifice transluminal endoscopic surgery (NOTES). Submucosal space surgery or third space surgery with the use of flexible endoscopy allows for decreased morbidity and hospital length of stay with equivalent outcomes for patients. In the case of achalasia, per oral endoscopic myotomy (POEM) allows for management of refractory cases in setting of previous Heller Myotomy or in patients whom laparoscopic or thoracoscopic surgery is contraindicated. Lastly, POEM more directly divides circular muscular layer of esophagus without destroying surrounding structures that exist to prevent reflux. The innovations in endoscopic surgery began in the animal lab with experiments in the porcine model to develop a way to access the peritoneal cavity through an entry point in the gastric mucosa. Over the last 10 years, the biggest treatment innovations in endoscopy have focused on management of achalasia with the use of POEM. POEM became possible as technology was developed that revolutionized the use of flexible technology and the methods of mucosal closure. In addition to benign esophageal disease, endoscopic methods improved in management of esophageal malignancy with endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD). The innovations of endoscopic surgery have been developed through the utilization of the submucosal space as a method to ensure adequate closure of the mucosal entry point into the peritoneal cavity. The goal of this review paper is to explore POEM and other techniques in endoscopic esophageal surgery for the management of esophageal diverticulum, submucosal tumors, gastroparesis, and gastrointestinal esophageal reflux disease.

Abstract
BACKGROUND Data on the long-term outcomes of gastric peroral endoscopic myotomy (G-POEM) for refractory gastroparesis are lacking. We report the results of a large multicenter long-term follow-up study of G-POEM for refractory gastroparesis. METHODS This was a retrospective multicenter study of all G-POEM operations performed in seven expert French centers for refractory gastroparesis with at least 1 year of follow-up. The primary endpoint was the 1-year clinical success rate, defined as at least a 1-point improvement in the Gastroparesis Cardinal Symptom Index (GCSI). RESULTS 76 patients were included (60.5 % women; age 56 years). The median symptom duration was 48 months. The median gastric retention at 4 hours (H4) before G-POEM was 45 % (interquartile range [IQR] 29 % - 67 %). The median GCSI before G-POEM was 3.6 (IQR 2.8 - 4.0). Clinical success was achieved in 65.8 % of the patients at 1 year, with a median rate of reduction in the GCSI score of 41 %. In logistic regression analysis, only a high preoperative GCSI satiety subscale score was predictive of clinical success (odds ratio [OR] 3.41, 95 % confidence interval [CI] 1.01 - 11.54; P = 0.048), while a high rate of gastric retention at H4 was significantly associated with clinical failure (OR 0.97, 95 %CI 0.95 - 1.00; P = 0.03). CONCLUSIONS The results confirm the efficacy of G-POEM for the treatment of refractory gastroparesis, as evidenced by a 65.8 % clinical success rate at 1 year. Although G-POEM is promising, prospective sham-controlled trials are urgently needed to confirm its efficacy and identify the patient populations who will benefit most from this procedure.

Li P, Ma B, Gong S, Zhang X, Li W. Gastric per-Oral Endoscopic Myotomy for Refractory Gastroparesis: A Meta-Analysis. J Gastrointest Surg 2021; 25:1108-1116. [PMID: 32394124 DOI: 10.1007/s11605-020-04520-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Accepted: 01/14/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The emerging gastric per-oral endoscopic myotomy (G-POEM) is becoming an alternative treatment method for gastroparesis. This study aimed to evaluate the feasibility and safety of G-POEM for gastroparesis. METHODS Relevant publications were identified through searching PubMed, EMBASE, Cochrane Library, and Web of Science before April 1, 2019. Studies presenting the clinical data of G-POEM for the treatment of gastroparesis were included. Data about effectiveness and safety were extracted, pooled, and analyzed. Forest plots were graphed based on random effects models. RESULTS A total of 272 patients representing 8 studies were eligible for analysis. The pooled rates of GCSI at preprocedure, 1-3 months, 6 months, and 12 months, were 3.25 (95% CI, 2.75-3.75), 1.80 (95% CI, 1.10-2.49), 1.56 (95% CI, 0.45-2.68), and 1.10 (95% CI, 0.75-1.45), respectively. The pooled results of 4-h GES pre- and post-G-POEM were 41.89% (95% CI, 32.75-51.03%) and 16.48% (95% CI, 9.83-23.14%), respectively. Furthermore, the pooled clinical response rate was 84% (95% CI, 77-89%). The GES improvement rate and GES normal rate were also analyzed, and the results were 84% (95% CI, 77-90%) and 53% (95% CI, 39-66%), respectively. Finally, the pooled adverse events rate was 12% (95% CI, 6-19%). CONCLUSIONS G-POEM was shown to be feasible and safe for the treatment of gastroparesis with various etiologies, which could be a potential first-line therapy for certain patients. Future studies are needed to investigate the appropriate patients for G-POEM to explore the "most beneficial" subgroup of patients.

Significant changes in impedance planimetry (EndoFLIP™) measurements after peroral pyloromyotomy for delayed gastric emptying. Surg Endosc 2021; 36:1536-1543. [PMID: 33742274 DOI: 10.1007/s00464-021-08441-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 03/05/2021] [Indexed: 01/17/2023]
Abstract
BACKGROUND The endoluminal functional lumen imaging probe (FLIP) can be used to obtain real-time measurements of the diameter (Dmin), cross-sectional area (CSA), and distensibility of the pylorus before and after peroral pyloromyotomy (POP), an emerging endoscopic treatment for delayed gastric emptying. Our study aims to report our single-center experience in performing POP with FLIP measurements before and after pyloromyotomy. METHODS A retrospective review of a prospectively maintained gastroesophageal database was performed. Demographic and perioperative data, including intraoperative FLIP measurements of the pylorus before and after POP, were analyzed. Measurements were compared using paired t tests. RESULTS Thirty-four patients underwent POP between February 2017 and July 2020. Twenty-three (67.7%) patients were male and the average age was 59 years. The etiology of delayed gastric emptying was post-vagotomy in 22 patients, idiopathic gastroparesis in 7 patients, and diabetic gastroparesis in 5 patients. There were no significant differences in pre-myotomy or post-myotomy FLIP measurements when comparing the post-vagotomy versus the gastroparesis groups. There were significant increases in Dmin, CSA, and distensibility index when comparing pre-myotomy and post-myotomy readings for all patients (all p < 0.001). At follow-up, 64.7% of patients reported resolution of all symptoms. CONCLUSION POP is an effective intervention in patients with delayed gastric emptying. Significant changes in FLIP measurements before and after POP suggest that FLIP may be a useful adjunct in guiding the management of delayed gastric emptying.

Abstract
Gastroparesis (GP) is commonly seen in hospitalized patients. Refractory vomiting and related dehydration, electrolyte abnormalities, and malnutrition are indications for hospital admission. In addition, tube feeding intolerance is a common sign of gastric dysmotility in critically ill patients. The diagnosis and management of GP in the hospital setting can be quite challenging. Diagnostic tests are often deferred because of patient intolerance of the oral meal for standard scintigraphy or severity of the primary disease. The diagnosis of GP is often established on the basis of clinical scenario and risk factors for gastric motor dysfunction. Medical therapy in GP is directed toward controlling nausea and vomiting by prokinetic and antinausea medications and correcting nutrition risks or treating malnutrition with nutrition therapy. Enteral nutrition is the preferred nutrition intervention for patients with GP. Delayed gastric emptying in critically ill patients has a negative impact on the timely delivery of enteral feeding and meeting the energy and protein goals. Measures to improve gastric tolerance or provide feeding beyond the stomach are often needed, since early enteral nutrition has been an important target of therapy for critically ill patients. This review will address the current understanding of the mechanisms of GP and feeding intolerance in critical illness, diagnostic workup, drug therapies, and interventions to improve the provision of enteral nutrition in hospital settings when gastric dysmotility is present or suspected.

Abstract
BACKGROUND Gastroparesis (GPS) is a rare disease with multiple etiologies that results in delayed gastric emptying. Diagnosis of GPS can be challenging due to its rather complex clinical presentation. Pharmacologic refractory cases require surgical interventions, all of which have yet to be standardized and characterized. OBJECTIVES We present a review of the literature and provide an update of current therapies for patients with GPS. SETTING Department of General Surgery, Academic Hospital, United States. METHODS We conducted a comprehensive search in PubMed, Google Scholar, and Embase of English-written articles published in the last 38 years, with an advance title search of "gastroparesis management." Other keywords included: "surgical management" and "refractory gastroparesis." Further references were obtained through cross-reference. RESULTS A total of 12,250 articles were selected after eliminating duplicates. Following thorough screening of selection criteria, 68 full-text articles were included for review. CONCLUSION GPS is a challenging disease to manage. Nutritional support must remain the primary approach, followed by either medical or surgical treatment modalities if necessary. In patients with refractory gastroparesis, adjunctive therapies have been proposed as promising long-term options.

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
INTRODUCTION Per-oral endoscopic pyloromyotomy (POP) is a promising new therapy in the treatment of gastroparesis, where the pyloric muscle is cut using an endoscopic tunneling technique. This study was designed to report outcomes from our initial experience and compare the rate of complications to the laparoscopic equivalent using the American College of Surgeons (ACS) risk calculator. METHODS Patients who underwent POP between August 2018 to May 2019 were prospectively followed in a database approved by the institutional review board. Preoperatively, patients were evaluated objectively with a 4-hour gastric emptying study (GES). Following POP, all patients were invited for repeat GES 3 months postoperatively. The same cohort was entered into the ACS risk calculator using laparoscopic pyloromyotomy (LPM) as the selected procedure. Complication risk of LPM was then compared with the actual complication rate of POP. RESULTS There were 11 patients that met study criteria (median age 52). Sixty-four percent (7/11) of patients agreed to do repeat GES postoperatively. Of those, 6 of 7 (86%) had normal GES (<10% emptying at 4 h) and the mean improvement was 36.4%. All patients were entered into the ACS risk calculator in which LPM (CPT code 43800) was used as a control. The postoperative complication rate was less than the median predicted risk of LPM in all categories including overall complications (0% vs. 10.05%), return to the operating room, (0% vs. 2.68%), and sepsis (0% vs. 1.42%). The rate of readmission (9% vs. 6.29%, P=0.65) was higher in the POP group than LPM predicted. Length of stay for all patients was significantly shorter than predicted (1.8 vs. 4.6 d, P<0.001). CONCLUSIONS All POP patients had objective improvement in their GES and 86% had normal GES following this procedure. POP had significantly lower morbidity and reduced length of stay compared with that predicted of the laparoscopic equivalent using the ACS risk calculator.

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
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
Achalasia is a type of esophageal motility disorder, consisting of relaxation dysfunction of the lower esophagus and disturbed esophageal peristalsis. Related clinical symptoms include dysphagia, regurgitation, chest pain, and weight loss. Traditional treatment options include endoscopic botulinum toxin injection, endoscopic pneumatic dilation, and laparoscopic Heller’s myotomy. These therapies mainly relieve symptoms by reducing the pressure on the lower esophageal sphincter and reducing blood flow resistance at the esophagogastric junction. Based on endoscopic submucosal dissection and natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) is a purely endoscopic method of myotomy with minimal invasiveness and a low rate of adverse events when performed by experienced operators. Since then, numerous studies have shown the significant clinical efficacy and safety of POEM. The purpose of this article is to introduce different modified POEMs, special indications for different POEMs, and their advantages as well as disadvantages.

Abstract
BACKGROUND AND AIMS Endoluminal functional luminal imaging probe (EndoFLIP) is an imaging tool that measures the physiologic characteristics of GI sphincters. In this study, we used EndoFLIP to evaluate the association between the pyloric physiologic measurements and the clinical outcomes of gastric peroral endoscopic myotomy (G-POEM) in patients with refractory gastroparesis. METHODS Thirty-seven patients from 5 centers who underwent G-POEM for management of refractory gastroparesis and had EndoFLIP measurements were evaluated. Cross-sectional area (CSA), balloon pressure, and the distensibility index (DI) of the pylorus were evaluated by EndoFLIP at 40 mL and 50 mL balloon fills before and after G-POEM. One-year clinical success and change in gastric emptying study 3 months after the G-POEM procedure were compared with the EndoFLIP measurements. RESULTS Clinical success was achieved in 26 (70%) patients. Post-G-POEM CSA and DI were significantly higher in the clinical success group with both 40-mL volume distension (CSA: 89.9 ± 64.8 vs 172.5 ± 71.9 mm2, P =.003; DI: 5.8 ± 4.4 vs 8.8 ± 6.1 mm2/mm Hg, P =.043) and 50-mL volume distention (CSA: 140.1 ± 89.9 vs 237.5 ± 80.3 mm2, P =.003; DI: 5.6 ± 3.3 vs 9.9 ± 6.6 mm2/mm Hg, P =.049). CSA using 40-mL volume distention with an area under the curve of 0.83 yielded a specificity of 91% and a sensitivity of 71% at a cutoff point of 154 mm2. CONCLUSIONS Post-G-POEM CSA of the pylorus is associated with clinical success and improvement in a gastric emptying scan after G-POEM. EndoFLIP measurements of the pylorus have the potential to be used as a tool to predict the clinical outcome of G-POEM.

Abstract
Gastroparesis is characterized by delayed gastric emptying, with symptoms such as nausea, vomiting and abdominal pain, in the absence of mechanical obstruction. In most cases, it is idiopathic although diabetes mellitus is another leading cause. The physiology of gastric emptying is a complex process which is influenced by various inputs including the central nervous system, enteric nervous system and gut hormones. Developments in our understanding of gastroparesis have now demonstrated dysfunction in these systems, thus disrupting normal gastric emptying. Once mechanical obstruction is excluded, gastric scintigraphy remains the gold standard for diagnosis although wireless motility capsule and breath testing are alternative methods for diagnosis. Treatment for gastroparesis is challenging, and widely available therapies are often limited either by their poor evidence for efficacy or concerns over their long-term safety profile. Novel prokinetic agents have shown initial promise in clinical trials, and new endoscopic techniques such as gastric per-oral endoscopic myotomy are emerging. These new treatment modalities may provide an option in refractory gastroparesis with the adage of reduced morbidity compared to surgical treatments.

Gastric Per Oral Pyloromyotomy for Post-Vagotomy-Induced Gastroparesis Following Esophagectomy. J Gastrointest Surg 2020; 24:715-719.

Abstract
BACKGROUND Following the success of per-oral endoscopic myotomy (POEM) for achalasia, application of this minimally invasive skillset has broadened to other disease processes. Since 2013, gastric per-oral pyloromyotomy (GPOP) has become an increasingly accepted therapy for refractory gastroparesis. Although it does not treat the underlying etiology of the disease, pyloromyotomy has demonstrated measurable improvements in gastric emptying scintigraphy, nausea, and quality of life. Gastroparesis is a common complication of esophagectomy due to the inherent vagotomy that occurs during creation of the gastric conduit. Fifteen to 30% of post-esophagectomy patients develop gastroparesis with a large portion of them reporting symptoms refractory to medical therapy, botox injection, and endoscopic dilation. Therefore, GPOP may have the potential to offer symptomatic relief to a significant population of debilitated post-esophagectomy patients. MATERIALS AND METHODS The procedure was recorded using standard operating room equipment. Materials utilized included high-definition single-channel gastroscope, therapeutic overtube, clear endoscopic cap, triangle tip (TT) knife, ERBE energy source, endoscopic clips, sclerotherapy needle, methylene blue with epinephrine, and CO2 insufflator. RESULTS We present a video of GPOP for a 71-year-old male with post-vagotomy-induced gastroparesis after esophagectomy. His pre-operative course was significant for persistent nausea and vomiting, diet intolerance, 20 lb weight loss, and frequent hospitalizations for aspiration pneumonia. Post-operatively, the patient recovered well and was discharged home on post-operative day 1 on a liquid diet. At 3-week follow-up, his nausea, vomiting, and PO intolerance had improved. At 6-month follow-up, he had no recent admissions for aspiration pneumonia and his pylorus remained widely patent on EGD. CONCLUSIONS GPOP status post-esophagectomy presented multiple challenges: difficulty maintaining field of view and insufflation, establishing tension and counter tension for the mucosotomy, and a limited working space. With care and patience, endoscopists trained to perform POEM may apply their skillset to help a large population of patients suffering with post-esophagectomy gastroparesis.

Abstract
Gastroparesis is delayed gastric emptying in the absence of mechanical obstruction. Cases are attributed to narcotic use, smoking, diabetes, and postsurgical complications; however, several incidences are unknown. Treatment options include diet modification, gut-stimulating medications (e.g., metoclopramide, domperidone), laparoscopic pyloroplasty, and, in the most severe cases, partial gastrectomy with Roux-en-Y reconstruction. Recently, a novel therapy has been developed, peroral endoscopic pyloromyotomy (POP). This procedure is similar to a laparoscopic pyloroplasty; however, it is performed completely endoscopically, thus negating the need for incisions. Here we present a case of gastroparesis treated with this novel technique.

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
Gastroparesis is a debilitating disease of insufficient gastric emptying and visceral hypersensitivity characterized by nausea, vomiting, early satiety, and bloating. Gastric emptying scintigraphy (GES), in combination with typical symptoms and normal esophagogastroduodenoscopy findings, is used to diagnose the disease. Gastric per-oral endoscopic pyloromyotomy (G-POEM) has emerged as a novel technique for treating gastroparesis, with up to an 80% success rate. This procedure involves myotomy of the distal stomach. We hypothesize that responders to this therapy are characterized by more distal dysmotility than nonresponders, as defined by GES retention patterns. Methods: We used regional gastric emptying measurements from diagnostic GES to determine the proximal or distal predominance of disease for each patient. We then compared treatment response and symptoms in each patient to total gastric half-emptying time (T½), proximal gastric T½, and a ratio comparing the 2 values. Results: In total, 47 patients underwent G-POEM during the study period. A significant difference (P < 0.01) was found in proximal-to-total T½ ratio between responders and nonresponders. A significant difference between pre- and postprocedural proximal-to-total T½ ratios was identified for each patient. No correlations were identified between motility patterns and symptoms or in motility patterns among the different etiologies of the disease. Conclusion: Proximal-to-total T½ ratio may represent an important patient selection factor for G-POEM versus other treatment modalities going forward. Local retention patterns in GES may not inform the symptom profile in gastroparesis.

Abstract
Gastroparesis is defined by delayed gastric emptying (GE) and symptoms of nausea, vomiting, bloating, postprandial fullness, early satiety and abdominal pain. Most common aetiologies include diabetes, postsurgical and postinfectious, but in many cases it is idiopathic. Clinical presentation and natural history vary by the aetiology. There is significant morbidity and healthcare utilisation associated with gastroparesis. Mechanistic studies from diabetic animal models of delayed GE as well as human full-thickness biopsies have significantly advanced our understanding of this disorder. An innate immune dysregulation and injury to the interstitial cells of Cajal and other components of the enteric nervous system through paracrine and oxidative stress mediators is likely central to the pathogenesis of gastroparesis. Scintigraphy and 13C breath testing provide the most validated assessment of GE. The stagnant gastroparesis therapeutic landscape is likely to soon see significant changes. Relatively newer treatment strategies include antiemetics (aprepitant), prokinetics (prucalopride, relamorelin) and fundic relaxants (acotiamide, buspirone). Endoscopic pyloromyotomy appears promising over the short term, especially for symptoms of nausea and vomiting. Further controlled trials and identification of the appropriate subgroup with pyloric dysfunction and assessment of long-term outcomes are essential. This review highlights the clinical presentation, diagnosis, mechanisms and treatment advancements for gastroparesis.

Abstract
BACKGROUND AND AIMS Gastric peroral endoscopic myotomy (G-POEM) is a novel minimally invasive technique in endosurgery. Data is limited as to its efficacy, safety, and predictive factors. We conducted this meta-analysis to evaluate the clinical outcomes of G-POEM and used the outcomes of surgical pyloroplasty as a comparator group in the treatment of refractory gastroparesis. METHODS We searched multiple databases from inception through March 2019 to identify studies that reported on G-POEM and pyloroplasty in gastroparesis. Our primary outcome was to analyze and compare the pooled rates of clinical success, in terms of Gastroparesis Cardinal Symptom Index (GCSI) score and 4-h gastric emptying study (GES) results, with G-POEM and pyloroplasty. RESULTS Three hundred and thirty-two and 375 patients underwent G-POEM (11 studies) and surgical pyloroplasty (seven studies), respectively. The pooled rate of clinical success, based on the GCSI score, with G-POEM was 75.8% (95% CI 68.1-82.1, I2 = 50) and with surgical pyloroplasty was 77.3% (95% CI 66.4-85.4, I2 = 0), with no significance, p = 0.81. The pooled rate of clinical success, based on the 4-hour GES results, with G-POEM was 85.1% (95% CI 68.9-93.7, I2 = 74) and with surgical pyloroplasty was 84% (95% CI 64.4-93.8, I2 = 81), with no significance, p = 0.91. The overall adverse events were comparable. Based on meta-regression analysis, idiopathic gastroparesis, prior treatment with botulinum toxin and gastric stimulator seemed to predict clinical success with G-POEM. CONCLUSION G-POEM demonstrates clinical success in treating refractory gastroparesis. Idiopathic gastroparesis, prior treatment with botulinum injections and gastric stimulator appear to have positive predictive effects on the 4-h GES results after G-POEM. Outcomes seem comparable to surgical pyloroplasty.

Abstract
This review covers the epidemiology, pathophysiology, clinical features, diagnosis, and management of diabetic gastroparesis, and more broadly diabetic gastroenteropathy, which encompasses all the gastrointestinal manifestations of diabetes mellitus. Up to 50% of patients with type 1 and type 2 DM and suboptimal glycemic control have delayed gastric emptying (GE), which can be documented with scintigraphy, 13C breath tests, or a wireless motility capsule; the remainder have normal or rapid GE. Many patients with delayed GE are asymptomatic; others have dyspepsia (i.e., mild to moderate indigestion, with or without a mild delay in GE) or gastroparesis, which is a syndrome characterized by moderate to severe upper gastrointestinal symptoms and delayed GE that suggest, but are not accompanied by, gastric outlet obstruction. Gastroparesis can markedly impair quality of life, and up to 50% of patients have significant anxiety and/or depression. Often the distinction between dyspepsia and gastroparesis is based on clinical judgement rather than established criteria. Hyperglycemia, autonomic neuropathy, and enteric neuromuscular inflammation and injury are implicated in the pathogenesis of delayed GE. Alternatively, there are limited data to suggest that delayed GE may affect glycemic control. The management of diabetic gastroparesis is guided by the severity of symptoms, the magnitude of delayed GE, and the nutritional status. Initial options include dietary modifications, supplemental oral nutrition, and antiemetic and prokinetic medications. Patients with more severe symptoms may require a venting gastrostomy or jejunostomy and/or gastric electrical stimulation. Promising newer therapeutic approaches include ghrelin receptor agonists and selective 5-hydroxytryptamine receptor agonists.

Abstract
PURPOSE OF REVIEW Peroral endoscopic myotomy (POEM) and gastric peroral endoscopic myotomy (G-POEM) are minimally invasive endoscopic procedures for the treatment of esophageal motility disorders and refractory gastroparesis, respectively. In this review, we highlight the most recent publications on the technical aspects of POEM and G-POEM. RECENT FINDINGS POEM has evolved into a standard therapeutic option in patients with all achalasia subtypes with excellent durability and safety profile. G-POEM is a novel endoscopic procedure with promising results in terms of efficacy, safety, and symptom improvement in patients with refractory gastroparesis. SUMMARY POEM and G-POEM are novel endoscopic procedures. Practice patterns vary among endoscopists and procedure techniques continue to evolve. Comparative studies examining outcomes of different techniques are needed.

Abstract
OBJECTIVE For patients with gastroparesis, temporary pyloric disruption has been shown to improve symptoms and gastric emptying. Per-oral pyloromyotomy (POP) is an innovative endoscopic procedure to divide the pylorus from within a submucosal tunnel, as a corollary to surgical pyloromyotomy. Here we evaluate subjective and objective outcomes 12-weeks after POP at a high volume center. METHODS The first 100 consecutive patients undergoing POP were included, with procedure dates between January 2016 and October 2017. Patients were evaluated using the Gastroparesis Cardinal Symptom Index (GCSI), and 4-hour solid-phase scintigraphic gastric emptying studies (GES) prior to procedure and at 90 days post-POP RESULTS:: The study cohort was 85% female with a mean age of 45.0 ± 14.6 years. Gastroparesis etiologies were divided among idiopathic (56%), diabetic (21%), postsurgical (19%), and other in 4%. There were 67% of the patients who had previous endoscopic or surgical interventions for gastroparesis. Most POP procedures were performed in the operating room (97%) and were completed in an average of 33 minutes. Ten patients incurred complications (10%), which included 1 diagnostic laparoscopy and 2 cases of gastrointestinal bleeding. Overall GCSI improved from a preoperative mean of 3.82 ± 0.86 to 2.54 ± 1.2 (P < 0.001). The improvement in each GCSI subscore was also highly statistically significant. Among the patients with postoperative GES available, 78% had objectively better 4-hour emptying with a mean improvement in retention by 23.6% (P < 0.001). This included 57% of patients with normal gastric emptying post-POP. CONCLUSION For patients with medically refractory gastroparesis, POP results in both subjective and objective improvement in the majority of patients. Prior intervention does not obviate POP as a therapeutic option. POP should be included along the treatment algorithm for patients with gastroparesis as an organ-sparing procedure.
