Abstract
BACKGROUND Submucosal tumors (SMTs) of the gastrointestinal tract are a rare pathological entity comprising a wide variety of neoplastic and non-neoplastic lesions. Even if most SMTs are benign tumors (e.g., leiomyomas), a smaller portion may have a malignant potential (e.g., gastrointestinal stromal tumor (GIST)). Preoperative diagnosis of SMT in bariatric patients may arise challenging clinical dilemmas. Long-term surveillance may be difficult after bariatric surgery. Moreover, according to SMT location, its presence may interfere with planned surgery. Submucosal tunneling endoscopic resection (STER) has emerged as an effective approach for minimally invasive en bloc excision of SMTs. This is the first case series of STER for SMTs before bariatric surgery. METHODS Seven female patients underwent STER for removal of SMTs before bariatric surgery. All lesions were incidentally diagnosed at preoperative endoscopy. STER procedural steps comprised mucosal incision, submucosal tunneling, lesion enucleation, and closure of mucosal defect. RESULTS En bloc removal of SMT was achieved in all cases. Mean procedural time was of 45 min (SD 18.6). No adverse event occurred. Mean size of the lesions was 20.6 mm (SD 5.8). Histological diagnoses were 5 leyomiomas, 1 lipoma, and 1 low grade GIST. Bariatric procedure was performed after a mean period of 4.1 months (SD 1.6) from endoscopic resection. CONCLUSION STER is a safe and effective treatment for the management of SMT even in bariatric patients awaiting surgery. Preoperative endoscopic resection of SMTs has the advantages of reducing the need for surveillance and removing lesions that could interfere with planned surgery. STER did not altered accomplishment of bariatric procedures.

MARTINS RK, RIBEIRO IB, DE MOURA DTH, HATHORN KE, BERNARDO WM, DE MOURA EGH. PERORAL (POEM) OR SURGICAL MYOTOMY FOR THE TREATMENT OF ACHALASIA: A SYSTEMATIC REVIEW AND META-ANALYSIS. ARQUIVOS DE GASTROENTEROLOGIA 2020; 57:79-86. [DOI: 10.1590/s0004-2803.202000000-14] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 10/24/2019] [Indexed: 02/06/2023]
Abstract
ABSTRACT BACKGROUND: Achalasia is a neurodegenerative motility esophageal disorder characterized by failure of lower esophageal sphincter relaxation. The conventional treatment option for achalasia has been laparoscopic Heller myotomy (LHM). However, in 2010, Inoue et al. described peroral endoscopic myotomy (POEM), a minimally invasive procedure, as an alternative therapy. To date, some studies with small sample sizes have aimed to compare outcomes of LHM vs POEM. OBJECTIVE: Thus, the aim of this study is to perform a systematic review and meta-analysis to better evaluate the efficacy and safety of these two techniques. METHODS: Individualized search strategies were developed from inception through April 2019 in accordance with PRISMA guidelines. Variables analyzed included operative time, overall adverse events rate, post-procedure gastroesophageal reflux disease (GERD), hospitalization length, post-procedure pain score, and Eckardt Score reduction. RESULTS: Twelve cohort trials were selected, consisting of 893 patients (359 in POEM group and 534 in LHM.) No randomized clinical trials were available. There was no difference in operative time (MD= -10,26, 95% CI (-5,6 to 8,2), P<0.001) or Post-Operative Gastroesophageal Reflux (RD: -0.00, 95%CI: (-0.09, 0.09), I2: 0%). There was decreased length of hospital stay for POEM (MD: -0.6, 95% CI (-1.11, -0.09), P=0.02), and an increased mean reduction in Eckardt score in POEM patients (MD = -0.257, 95% CI: (-0.512 to -0.002), P=0.048), with similar rates of adverse events. CONCLUSION: POEM demonstrated similar results compared to laparoscopic Heller myotomy with regards to improvement of dysphagia, post-procedure reflux, and surgical time, with the benefit of shorter length of hospital stay. Therefore, POEM can be considered an option for patients with achalasia.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has become an acceptable incisionless treatment for achalasia based on encouraging outcomes in multiple series worldwide. This report reflects our early experience. METHODS Data were collected prospectively on all patients undergoing POEM between June 2011 and April 2016 under IRB approval. Diagnosis of achalasia was confirmed by standard preoperative work-up. Primary outcome was symptom relief, measured by Eckardt score. Secondary outcomes were operative time, length of stay (LOS), adverse events, failure, and recurrence. RESULTS Fifty patients were included; 30 were female. Mean age was 55.7 ± 17.7 years. Mean BMI was 29.5 ± 9.2. Median OR time was 133.5 minutes (range 70-462); average myotomy was 13.1 ± 2.3 cm. One early case was converted to a laparoscopic Heller myotomy due to extensive submucosal fibrosis from a recent Botox injection. Two cases were aborted; one due to extensive submucosal fibrosis and the other to intraoperative capnopericardium. Median LOS was 1 day (range 0.8-8). Two major complications occurred: intraoperative cardiac arrest due to capnopericardium and postoperative submucosal hemorrhage. There were no deaths. Mean postoperative Eckardt score was 1.0 ± 1.9 (range 0-8) at 2-6 weeks (vs. preoperative score 7.7 ± 2.8; P < .0001); mean dysphagia component 0.35 ± 0.28 (vs. preoperative score 2.6 ± 0.7; P < .0001). Two recurrences were identified, both at 6 months. CONCLUSIONS POEM is a safe and durable treatment for achalasia in the short term. We demonstrated marked improvement of symptoms in all completed cases. There was an acceptable serious adverse event rate of 4%, failure of 6% due to patient selection, and recurrences occurring in only 4% of cases.

Systematic Review and Meta-Analysis of Perioperative Outcomes of Peroral Endoscopic Myotomy (POEM) and Laparoscopic Heller Myotomy (LHM) for Achalasia. Surg Laparosc Endosc Percutan Tech 2018; 27:123-131.

Abstract
AIMS AND OBJECTIVES Laparoscopic Heller myotomy (LHM) is the preferred surgical method for treating achalasia. However, peroral endoscopic myotomy (POEM) is providing good short-term results. The objective of this systematic review and meta-analysis was to compare the safety and efficacy of LHM and POEM. MATERIALS AND METHODS A search of PubMed, Cochrane database, Medline, Embase, Science Citation Index, and current contents for English-language articles comparing LHM and POEM between 2007 and 2016 was performed. Variables analyzed included prior endoscopic treatment, prior medical treatment, prior Heller myotomy, operative time, overall complications rate, postoperative gastroesophageal reflux disease (GERD), length of hospital stay, postoperative pain score, and long-term GERD. RESULTS Seven trials consisting of 483 (LHM=250, POEM=233) patients were analyzed. Preoperative variables, for example, prior endoscopic treatment [odds ratio (OR), 1.32; 95% confidence interval (CI), 0.23-4.61; P=0.96], prior medical treatment [weighted mean difference (WMD), 1.22; 95% CI, 0.52-2.88; P=0.65], and prior Heller myotomy (WMD, 0.47; 95% CI, 0.13-1.67; P=0.25) were comparable. Operative time was 26.28 minutes, nonsignificantly longer for LHM (WMD, 26.28; 95% CI, -11.20 to 63.70; P=0.17). There was a comparable overall complication rate (OR, 1.25; 95% CI, 0.56-2.77; P=0.59), postoperative GERD rate (OR, 1.27; 95% CI, 0.70-2.30; P=0.44), length of hospital stay (WMD, 0.30; 95% CI, -0.24 to 0.85; P=0.28), postoperative pain score (WMD, -0.26; 95% CI, -1.58 to 1.06; P=0.70), and long-term GERD (WMD, 1.06; 95% CI, 0.27-4.1; P=0.08) for both procedures. There was a significantly higher short-term clinical treatment failure rate for LHM (OR, 9.82; 95% CI, 2.06-46.80; P<0.01). CONCLUSIONS POEM compares favorably to LHM for achalasia treatment in short-term perioperative outcomes. However, there was a significantly higher clinical treatment failure rate for LHM on short-term postoperative follow-up. Presently long-term postoperative follow-up data for POEM beyond 1 year are unavailable and eagerly awaited.

Abstract
OBJECTIVE To investigate the effects of sequential nutritional support on nutritional status and immune regulation in patients with early severe traumatic brain injury (STBI). PATIENTS AND METHODS A total of 62 patients diagnosed with STBI enrolled from Chaoyang Hospital (Beijing, China) from February 2015 to October 2016 were divided into two groups. The observational group (n=34) was given sequential nutritional support and the control group (n=28) was given the standard formula of whole protein enteral preparations. The energy supply for the two groups was 30 kcal/kg/d and protein 1.6 g/kg/d, respectively. The albumin (ALB), total protein (TP), high-sensitivity C-reactive protein (Hs-CRP), neuron-specific enolase (NSE), Glasgow Coma Score (GCS), and regulatory T cells before and after nutritional treatment were measured in both groups. RESULTS At the 14th day, the levels of ALB (41.7±4.2 g/L) and TP (70.6±4.9 g/L) were significantly higher than those in the control group (33.5±2.3 g/L and 62.3±3.9 g/L) (P<0.05). The levels of Hs-CRP and NSE were significantly lower in the observational group (0.96±0.82 mg/L and 11.96±7.82 ng/L) than in the control group (1.17±0.74 mg/L and 19.17±6.74 ng/L) (P<0.05). The GCS score in the observational group (11.5±2.9) was significantly higher than that in the control group (8.1±1.7) (P<0.05). The percentage of Tregs in the peripheral CD4+ lymphocytes was significantly lower in the observational group than in the control group (P<0.05). CONCLUSION The effect of sequential nutritional support is better than conventional nutritional support in patients with STBI. The findings call for early identification of malnutrition and individual nutritional support.

Abstract
Achalasia is an acquired neuromuscular disorder that has been treated using a variety of modalities throughout medical history. Recently, the technique of per oral endoscopic myotomy (POEM) was introduced to treat the disease using a truly minimally invasive, natural orifice technique that is rapidly being adopted across the world. This review outlines the development of POEM, the technique itself, and gives a comparison to other procedures, specifically laparoscopic Heller myotomy (LHM).

Abstract
The EndoFLIP (Endolumenal Functional Lumen Imaging Probe, Crospon Inc, Galway, Ireland) device uses the technique of impedance planimetry to evaluate dimensions and distensibility of the upper and lower esophageal sphincter. The null hypotheses for this study were that EndoFLIP variables would be stable between anesthestic episodes and would not be affected by body position when evaluating the upper and lower esophageal sphincters in healthy dogs. During each of three consecutive general anesthesia episodes administered to eight healthy adult research colony dogs with a standardized protocol, the EndoFLIP catheter was positioned to measure cross-sectional area, intrabag pressure, upper and lower esophageal sphincter length at two different balloon fill volumes (30 and 40 mL) and two body positions (lateral and dorsal recumbency). From these measured variables, a distensibility index was also calculated. Mixed effect analysis of variance was used to evaluate the fixed marginal and interaction effects of anesthesia episode, body position, and balloon volume on measured and calculated variables. For the upper esophageal sphincter significant interactions were present between anesthetic episode and body position for all variables except intrabag pressure; adjusting for body position significant differences were present between anesthetic episodes for all variables except distensibility index; adjusting for anesthetic episode cross-sectional area, intrabag pressure, upper esophageal sphincter length and distensibility index were all affected by body position. For the lower esophageal sphincter distensibility index was the only variable where a significant interaction between anesthesia episode and body position occurred; cross-sectional area, intrabag pressure, and lower esophageal length were not significantly affected by anesthesia episode when adjusting for body position; distensibility index was the only variable significantly affected by body position. Measurements of the geometry of the lower esophageal sphincter as measured by the EndoFLIP device were consistent under conditions of general anesthesia. Similar measurements taken at the upper esophageal sphincter displayed greater variability between anesthetic episodes and were affected to a greater extent by body position. Body position should be standardized in studies using the EndoFLIP to assess geometric and functional characteristics of the upper and lower esophageal sphincters.

Abstract
BACKGROUND Achalasia is a rare esophageal motility disorder that is characterized by loss of peristalsis and failure of relaxation of the lower esophageal sphincter (LES), particularly during swallowing. This review focuses on the diagnosis of esophageal motility disorders as defined by the Chicago Classification ver 3.0, and presents management options with regard to per-oral endoscopic myotomy (POEM) as the treatment of choice. METHODS A concise review of literature was performed for articles related to the management of achalasia, and this was contrasted with our institution's current practice. RESULTS Achalasia is still incompletely understood, and management is focused on establishing a proper diagnosis, and relieving the obstructive symptoms. CONCLUSIONS Achalasia should be considered when dysphagia is present, and not otherwise caused by an obstruction or inflammation, and when criteria is met as per the Chicago Classification ver 3.0. Lowering LES tone and disruption of LES can be accomplished by various methods, most notably pneumatic balloon dilatation and surgical myotomy. POEM has been gaining momentum as a first line therapy for achalasia symptoms, and can be considered an important tool for motility disorders of the esophagus.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has emerged as an effective weight-loss procedure for morbid obesity that is also effective for treating comorbidities such as diabetes. However, it has been associated with the development of GERD postoperatively. The pathophysiology of post-LSG GERD is unknown, and current studies have shown conflicting results. The aim of our study is to shed light on this issue by investigating the effect of LSG on the lower esophageal sphincter (LES) function and the relationship of LES function to GERD symptoms. METHODS A prospective study of patients undergoing LSG from 10/2013 to 8/2014 at a single academic tertiary referral center was carried out. Patients undergoing a concomitant procedure such as hiatal hernia repair or laparoscopic gastric band removal were excluded. Distensibility of the LES was measured after pneumoperitoneum and after LSG. Baseline GERD-HRQL was obtained with follow-up GERD-HRQL and weight at 3 and 6 months. The primary outcomes measured were LES distensibility and GERD-HRQL scores after LSG. Our secondary outcome was a correlation between LES distensibility and GERD-HRQL scores after LSG. RESULTS Fifteen subjects were enrolled (5M/10F). Mean age was 51 years (30-71 years), and mean BMI 45 kg/m2 (30-58). We were able to obtain follow-up data for all patients at 3 months. Mean LES distensibility increased from 1.2 before LSG to 2.2 after LSG (p = 0.017). Median GERD-HRQL was 0 before LSG and remained essentially negative at 1 and 0 (3 and 6 months postoperatively, respectively). Three (27 %) of the patients had de novo GERD at 3 months following LSG. One (25 %) patient had remission of GERD. There was no correlation between LES distensibility and GERD symptoms. CONCLUSION While LSG weakens the LES immediately, it does not predictably affect postoperative GERD symptoms; therefore, distensibility is not the only factor affecting development of postoperative GERD, confirming the multifactorial nature of post-LSG GERD.

Abstract
We aimed to assess the short-term outcomes of per-oral endoscopic myotomy (POEM) compared with laparoscopic Heller myotomy (LHM) for achalasia through a meta-analysis of nonrandomized comparative studies.We searched PubMed, Embase, Medline, Cochrane Library, and Google Scholar for studies that compared POEM and LHM for achalasia and were published between January 1, 2008 and December 31, 2014. The Methodological Index for Nonrandomized Studies (MINORS) was used to evaluate the quality of the studies. Random- and fixed-effects meta-analytical models were used, and between-study heterogeneity was assessed.Four nonrandomized comparative studies that included 317 patients (125 in the POEM group and 192 in the LHM group) met our research criteria and were assessed. There were no differences between the POEM and LHM groups in terms of sex, preoperative Eckhart score, length of myotomy, operation time, length of hospital stay, and complications. The patients in the POEM group were older than those in the LHM group (MD =2.81, 95% CI 0.27-5.35; P = 0.03) with high between-study homogeneity (χ = 1.96, df = 2, I = 0%; P = 0.38). The patients in the POEM group had a lower Eckardt score after surgery compared with those in the LHM group (MD = -0.30, 95% CI -0.42 to -0.18; P < 0.001) with high between-study homogeneity (χ = 0.00, df = 1, I = 0%; P = 1.00).The efficacy and safety of POEM appear to be comparable to those of LHM. Multicenter and randomized trials with larger sample size are needed to further compare the efficacy and safety of POEM and LHM for the treatment of achalasia.

Abstract
Achalasia is a motility disorder of the esophagus characterized by dysphagia, regurgitation of undigested food, chest pain, weight loss and respiratory symptoms. The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry (HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type II achalasia are better after treatment compared to younger patients, males and type III achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies.

Abstract
Peroral endoscopic myotomy (POEM) is an innovative, minimally invasive, endoscopic treatment for esophageal achalasia and other esophageal motility disorders, emerged from the natural orifice transluminal endoscopic surgery procedures, and since the first human case performed by Inoue in 2008, showed exciting results in international level, with more than 4000 cases globally up to now. POEM showed superior characteristics than the standard 100-year-old surgical or laparoscopic Heller myotomy (LHM), not only for all types of esophageal achalasia [classical (I), vigorous (II), spastic (III), Chicago Classification], but also for advanced sigmoid type achalasia (S1 and S2), failed LHM, or other esophageal motility disorders (diffuse esophageal spasm, nutcracker esophagus or Jackhammer esophagus). POEM starts with a mucosal incision, followed by submucosal tunnel creation crossing the esophagogastric junction (EGJ) and myotomy. Finally the mucosal entry is closed with endoscopic clip placement. POEM permitted relatively free choice of myotomy length and localization. Although it is technically demanding procedure, POEM can be performed safely and achieves very good control of dysphagia and chest pain. Gastroesophageal reflux is the most common troublesome side effect, and is well controllable with proton pump inhibitors. Furthermore, POEM opened the era of submucosal tunnel endoscopy, with many other applications. Based on the same principles with POEM, in combination with new technological developments, such as endoscopic suturing, peroral endoscopic tumor resection (POET), is safely and effectively applied for challenging submucosal esophageal, EGJ and gastric cardia tumors (submucosal tumors), emerged from muscularis propria. POET showed up to know promising results, however, it is restricted to specialized centers. The present article reviews the recent data of POEM and POET and discussed controversial issues that need further study and future perspectives.

Abstract
In general, the treatment methods for esophageal achalasia are largely classified into four groups, including drug therapy using nitrite or a calcium channel blocker, botulinum toxin injection, endoscopic therapy such as endoscopic balloon dilation, and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913, but the most common approach has changed from open-chest surgery to laparoscopic surgery. Currently, the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy, to thoracoscopic surgery, and to laparoscopic surgery, the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux, but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently, a new endoscopic approach, peroral endoscopic myotomy (POEM), has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.

Abstract
INTRODUCTION Per-oral endoscopic myotomy (POEM) is an emerging treatment for achalasia. Pneumatic dilation, botulinum toxin injection, and previous myotomy increase the difficulty of subsequent Heller myotomy, but their impact on POEM remains unknown. The purpose of this study was to compare patients who had undergone prior treatment for their achalasia to those undergoing POEM as an initial therapy. METHODS AND PROCEDURES All patients undergoing POEM were entered into a prospective database from August 2012 to October 2014. Data collected included demographics, dysphagia and symptom survey scores, operative time, clips required for mucosotomy closure, perioperative complications and length of hospital stay. RESULTS Forty-five patients underwent POEM during the study period. Fifteen (30%) had undergone previous treatment (seven Botox injection, five pneumatic dilation and three Heller myotomy). Primary POEM patients were younger than those who had had prior treatment (mean age 46 ± 17 vs. 64 ± 12 years, p < 0.001), but gender, body mass index and ASA class were not significantly different. There were no conversions to Heller myotomy or perioperative complications in either group. Operative time for primary POEM was 103 ± 27 versus 102 ± 29 min following prior treatment (p = 0.84). Mucosotomy closure required a median 7 (4-16) and 8 (5-16) clips, respectively (p = 0.08). Length of stay was 1 day in each group. Median dysphagia scores decreased from 4 (0-5) to 1 (0-4) following primary POEM and 4 (0-5) to 0 (0-4) in the prior treatment group (p = 0.45) during a median follow-up of 10 months (5-17 months). All patients in each group expressed satisfaction with their procedure and would undergo the procedure again given the benefit of hindsight. CONCLUSION Per-oral endoscopic myotomy is a safe and effective treatment for achalasia which improves dysphagia and disease-specific quality of life. Previous endoscopic or laparoscopic treatment of achalasia does not affect the performance or early outcome of POEM.

Abstract
Achalasia is a motility disorder of the esophagus, characterized by aperistalsis of the esophageal body and incomplete relaxation of the lower esophageal sphincter (LES). Peroral endoscopic myotomy (POEM) is an emerging novel endoscopic procedure for the treatment of achalasia by incision of LES via a submucosal tunnel. On the basis of initial data suggesting an acceptable safety profile and excellent short-term symptom resolution, there is growing enthusiasm in favor of POEM. In this review we outline the technical aspects of POEM, summarize the available data on safety and outcomes, and suggest future directions for further advancement of this minimally invasive approach for the treatment of achalasia.
