Abstract
Background and aim Various techniques for direct biopsy from gastrointestinal subepithelial tumors (SETs) have been reported, although no standard method has been established. A common feature of these techniques is the removal of overlaying mucosa to enable direct biopsies from the SETs. These methods have been synthesized under the collective term "unroofing technique". We conducted a multicenter retrospective study to assess its efficacy and identify potential complications. Methods This study was conducted in 10 hospitals and involved all eligible patients who underwent unroofing techniques to obtain biopsies for gastrointestinal SETs between April 2015 and March 2021. The primary endpoint was the diagnostic accuracy of the unroofing technique, and the secondary endpoints were the incidence of adverse events and the factors contributing to the accurate diagnosis. Results The study included 61 patients with 61 gastrointestinal SETs. The median tumor size was 20 mm, and the median procedure time was 38 min, with 82% successful tumor exposure. The rate of pathological diagnosis was 72.1%. In 44 patients with a pathological diagnosis, two showed discrepancies with the postresection pathological diagnosis. No factors, including facility experience, organ, tumor size, or tumor exposure, significantly affected the diagnostic accuracy. There was one case of delayed bleeding and two cases of perforation. Conclusion The diagnostic yield of the unroofing technique was acceptable. The unroofing technique was beneficial regardless of institutional experience, organ, tumor size, or actual tumor exposure.

Abstract
BACKGROUND Several liquid-based cytology (LBC) methods are currently used, but the diagnostic accuracy of each method is not well known. We aimed to compare the diagnostic performance of SurePathTM LBC and conventional smear (CS) cytology in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) samples of esophageal, gastric, and duodenal lesions. METHODS As a prospective randomized noninferiority study, patients who needed EUS-FNA due to subepithelial mass in the upper gastrointestinal tract were randomly assigned 1:1 to the LBC and CS groups. Cytologic preparation was carried out using a crossover design where 1 method was used for the first needle-pass sample and another method was used for the second needle-pass sample. The primary outcome was to compare the diagnostic performance between LBC and CS using the final diagnosis as the gold standard. RESULTS A total of 87 patients were randomized and 60 patients were analyzed. There were no differences between LBC and CS in diagnostic accuracy (91.7% vs 86.7%, P = .380), sensitivity (97.7% vs 90.7%, P = .169), specificity (76.5% vs 76.5%, P > .99), negative predictive value (92.9% vs 76.5%, P = .225), or positive predictive value (91.3% vs 90.7%, P = .921). The background of LBC was less bloody than that of CSs (5.0% vs 53.3%, P < .001) and the sample preparation time of LBC was shorter than that of CSs (29 ± 7 seconds vs 90 ± 17 seconds, P < .001). CONCLUSION In the EUS-FNA of a subepithelial mass in the upper gastrointestinal tract, the diagnostic performance of LBC was not inferior to that of CS. The field of view was better in LBC, because the background was less bloody and necrotic. As LBC is more convenient to perform and takes shorter time, it is expected that it can replace the CS method for EUS-FNA samples.

Abstract
Gastric subepithelial tumors (SETs) are often incidentally found during examinations of the gastrointestinal tract. Able to arise from any layer of the stomach, these tumors are predominantly asymptomatic and are classified as either benign or malignant based on size, consistency, shape, and mobility as determined by endoscopic evaluation. We present the first reported case of a gastric SET presenting as a chronic organizing hematoma. In doing so, we discuss the necessity of multimodal imaging techniques and multidisciplinary management in identifying often obscure gastric SETs to intervene on potentially malignant masses early.

Abstract
INTRODUCTION Underwater endoscopic mucosal resection (UW-EMR) has been recently introduced as an effective technique for rectal third layer subepithelial tumors. Therefore, we aimed to assess the safety, efficacy, and procedure time of UW-EMR for upper gastrointestinal subepithelial tumors (SETs) originating from the deep mucosal and/or submucosal layers. METHODS Between August 2018 to July 2022, a total of 17 SETs (7 duodenal SETs, 6 gastric SETs, and 4 esophageal SETs) were included in this study. On endoscopic ultrasound examinations, the tumors were found to be embedded in the submucosa without muscularis propria invasion. All SETs were resected successfully using UW-EMR. The characteristics of the tumors and their R0 resection rate, adverse event rate, and recurrence rate were evaluated retrospectively. RESULTS The mean tumor size was 0.9 cm (range, 0.3-1.5 cm). En bloc resection and complete resection rates were 100%, respectively. The patients showed no complications such as perforation or bleeding. Histologic assessments of the resected tumors revealed 9 neuroendocrine tumors (7 on the duodenum, 2 on the stomach), 2 gastric cystica profunda, 1 gastric follicular lymphoma, 1 gastric fibromyxoma, 3 esophageal granular cell tumors, and 1 esophageal adenoid cystic carcinoma. The mean procedural time was 3.2 min (range, 1.3-8.7 minutes). The overall en bloc and complete resection rates were 100%, respectively. No recurrence was observed during the follow-up period. CONCLUSION UW-EMR is a safe and effective treatment for upper gastrointestinal SETs embedded in the submucosal layer. Further studies are needed to compare other endoscopic resection techniques.

Abstract
BACKGROUND AND AIM The small endoscopic ultrasound (EUS)-suspected gastric gastrointestinal stromal tumors (GISTs), gastric subepithelial tumors at the muscularis propria layer on EUS, are detected frequently. Bite-on-bite forceps biopsy and EUS-guided tissue sampling yield variable results. This study aimed to analyze clinicopathologic features of the small EUS-suspected gastric GISTs 2 cm or less in size and to evaluate the efficacy and safety of the endoscopic incisional biopsy (EIB) for these small tumors. METHODS This prospective study investigated 70 patients with small EUS-suspected gastric GISTs 2 cm or less in size in two stages. Firstly, 30 patients were recruited for the efficacy and safety evaluation of the EIB. Secondly, 40 patients were randomly assigned to receive either EIB or the bite-on-bite biopsy for comparison of the diagnostic yield, procedure time, and adverse event rate. RESULTS Combining two study stages, leiomyoma (74%) was diagnosed histologically to outnumber GIST (26%) with a diagnostic rate of 94% for patients receiving EIB. KIT exon 11 mutations (50%) and PDGFRA exon 12 mutations (16%) were detected in the small gastric GISTs. In the direct comparison, the diagnostic yield of EIB and the bite-on-bite biopsy was 85% and 50%, respectively (P = 0.018). There was no statistically significant difference of the mean procedure time or adverse event rate between these two groups. CONCLUSIONS Leiomyoma is more common than expected among these small tumors. Tissue diagnosis with an effective and safe sampling technique, such as EIB, is necessary for making further clinical decisions.

Abstract
Background: Considering the widespread use of esophagogastroduodenoscopy, the prevalence of upper gastrointestinal (GI) subepithelial tumors (SET) increases. For relatively safer removal of upper GI SETs, endoscopic submucosal dissection (ESD) has been developed as an alternative to surgery. This study aimed to analyze the outcome of endoscopic resection for SETs and develop a prediction model for the need for laparoscopic and endoscopic cooperative surgery (LECS) during the procedure. Method: We retrospectively analyzed 123 patients who underwent endoscopic resection for upper GI SETs between January 2012 and December 2020 at our institution. Intraoperatively, they underwent ESD or submucosal tunneling endoscopic resection (STER). Results: ESD and STER were performed in 107 and 16 patients, respectively. The median age was 55 years, and the average tumor size was 1.5 cm. En bloc resection was achieved in 114 patients (92.7%). The median follow-up duration was 242 days without recurrence. Perforation occurred in 47 patients (38.2%), and 30 patients (24.4%) underwent LECS. Most perforations occurred in the fundus. Through multivariable analysis, we built a nomogram that can predict LECS requirement according to tumor location, size, patient age, and sex. The prediction model exhibited good discrimination ability, with an area under the curve (AUC) of 0.893. Conclusions: Endoscopic resection is a noninvasive procedure for small upper-GI SETs. Most perforations can be successfully managed endoscopically. The prediction model for LECS requirement is useful in treatment planning.

Abstract
Simple Summary Gastrointestinal stromal tumors (GIST) are potentially malignant tumors and require evidence-based surgical and/or medical treatment. Laparoscopy has similar safety and prognostic outcomes to those of laparotomy and is currently a standard procedure for localized GISTs. However, surgery for gastric GISTs less than 2 cm may be re-evaluated due to the indolent nature of the GIST and other competing risks among GIST patients. A work-up with endoscopy and endoscopic ultrasonography as well as endoscopic or percutaneous biopsy is important for the preoperative diagnosis of GISTs. Medical treatment with tyrosine kinase inhibitors is the mainstay for recurrent/metastatic GISTs. The activity of an individual drug is well correlated with gene alterations, and, in the era of precision medicine, cancer genome profiling should be considered before medical treatment. Abstract Gastrointestinal stromal tumors (GISTs) are the most frequent malignant mesenchymal tumors in the gastrointestinal tract. The clinical incidence of GISTs is estimated 10/million/year; however, the true incidence is complicated by frequent findings of tiny GISTs, of which the natural history is unknown. The initial work-up with endoscopy and endoscopic ultrasonography plays important roles in the differential diagnosis of GISTs. Surgery is the only modality for the permanent cure of localized GISTs. In terms of safety and prognostic outcomes, laparoscopy is similar to laparotomy for GIST treatment, including tumors larger than 5 cm. GIST progression is driven by mutations in KIT or PDGFRA or by other rare gene alterations, all of which are mutually exclusive. Tyrosine kinase inhibitors (TKIs) are the standard therapy for metastatic/recurrent GISTs. Molecular alterations are the most reliable biomarkers for TKIs and for other drugs, such as NTRK inhibitors. The pathological and genetic diagnosis prior to treatment has been challenging; however, a newly developed endoscopic device may be useful for diagnosis. In the era of precision medicine, cancer genome profiling by targeted gene panel analysis may enable potential targeted therapy even for GISTs without KIT or PDGFRA mutations.

Abstract
INTRODUCTION Esophageal subepithelial lesions (SELs) are rare, and the majority of them are benign. SELs are often covered with normal mucosa, thereby resulting in some malignant SELs to be easily missed or misdiagnosed. We report 2 cases of esophageal intramural squamous cell carcinomas (SCCs) that presented as SELs and were endoscopically removed. PATIENT CONCERNS Case 1 is a 63-year-old man with abdominal distension; case 2 is a 65-year-old man with increasing dysphagia for 2 months. DIAGNOSIS In case 1, endoscopy showed a 1.5-cm mucosal eminence with normal overlying mucosa. Endoscopic ultrasound (EUS) revealed that it might be derived from the muscularis mucosa or submucosa. In case 2, endoscopy revealed a 1.2-cm hemispherical lesion covered with smooth mucosa. Furthermore, EUS revealed that this lesion might be derived from the submucosa. INTERVENTIONS In both cases, the lesions were removed by endoscopic submucosal dissection (ESD). Pathological examination revealed esophageal SCC nests with intramural growth patterns. OUTCOMES The first patient underwent postoperative radiotherapy, whereas the second patient did not receive any additional treatment. Both patients agreed to regular follow-up, and no tumor recurrence or metastasis was observed. CONCLUSION First, not all esophageal SELs are benign, and a small number of SELs can be malignant. Second, these cases illustrate the value of newer endoscopic techniques, especially ESD. Thus, it is important to be alert when visualizing the esophagus for the possibility of a subtle SEL so that further evaluation and treatment, if necessary, can be undertaken, ideally with a less invasive approach afforded by ESD.

Abstract
Recently, there have been important developments in minimally invasive full-thickness resection of subepithelial tumors (SETs) of the upper gastrointestinal tract. However, there remain challenges with techniques such as laparoscopy-endoscopy cooperative surgery (LECS) and non-exposed endoscopic wall-inversion surgery (NEWS). The aim of the present study was to further investigate the feasibility, efficacy and safety of laparoscopy-assisted endoscopic full-thickness resection (ETFR) of SETs and to evaluate the clinical outcomes. This retrospective study included 16 patients with upper gastrointestinal SETs who underwent laparoscopy-assisted EFTR between July 2016 and December 2017. The patient characteristics, surgical outcomes, postoperative course, results of the histopathological examination and short-term outcomes were reviewed and analyzed. A total of 10 patients in the LECS group and 6 patients in the NEWS group presented with SETs in the stomach (15 cases) or duodenum (1 case). The mean tumor size in the LECS group (5.6 cm) was larger compared with that in the NEWS group (2.1 cm). R0 resection was achieved in all patients, without adverse events or tumor recurrence. The NEWS group exhibited a lower white blood cell count and C-reactive protein level on the first postoperative day, reflecting the less prominent inflammatory response, less bleeding and shorter hospitalization. Therefore, laparoscopy-assisted EFTR by LECS and NEWS is a feasible and safe minimally invasive treatment option for upper gastrointestinal SETs in selected patients.

Abstract
OBJECTIVE Some gastrointestinal subepithelial tumors (SETs) have malignant potential and complete resection may be required. However, endoscopic submucosal dissection (ESD) can be a tedious procedure and requires a long and extensive training to master. Devices for endoscopic full-thickness resection (EFTR) are limited and are not widely available. We report here a simpler endoscopic method to resect small SETs using a commercially available endoscopic mucosal resection (EMR) kit and enucleation technique. METHODS All patients with SET who underwent device-assisted resection at our tertiary care hospital from April 2015 to November 2016 were enrolled in this retrospective study. All procedures were performed by a single expert endoscopist with an advanced endoscopy trainee. A mucosectomy and a limited dissection under mucosa were performed to preserve the mucosa before a device-assisted enucleation of the tumor to facilitate endoscopic closure of the defect closure in all cases. RESULTS A total of 12 patients aged 38-70 y, of whom six were males, were included. Most of the tumors originated from the muscularis propria and were located at the proximal gastric body. The mean procedural duration was 53 minutes (range 23-91 min). The average size of the lesions was 13 mm (range 9-21 mm). The mean duration of hospitalization was 1.3 days. Bleeding and intentional perforation were all successfully managed during the procedure and did not result in any clinically significant adverse event. CONCLUSION A device-assisted EFTR using a commercially available EMR kit is a safe and feasible method for the endoscopic resection of small gastric extrovert SETs.

Abstract
BACKGROUND AND AIM Immunohistological evaluations are essential for diagnosing subepithelial tumors (SET). However, endoscopic ultrasound-guided sampling using fine-needle aspiration (FNA) needles is limited in its ability to procure core tissue for immunostaining. Fine-needle biopsy (FNB) needles may mitigate this limitation. The present study aimed to examine the efficacy of FNB needles for procuring samples that enable the diagnosis of SET. METHODS One hundred sixty patients were included in the study and separated into those whose samples were obtained using FNB needles (FNB group) and those whose samples were procured using FNA needles (FNA group). Groups were compared regarding the conclusive diagnosis rate and unwarranted resection rate. Propensity score matching was introduced to reduce selection bias. RESULTS Rates at which conclusive diagnoses were reached through adequate immunohistological evaluations were 82% and 60% in the FNB and FNA groups, respectively; this difference was significant (P = 0.013). Unwarranted resection rate was significantly lower in the FNB group (2%) than in the FNA group (14%; P = 0.032). Multivariate analyses showed that lesions ≤20 mm were a significant risk factor for lower conclusive diagnosis rates following the use of FNB needles (P = 0.017). CONCLUSIONS Fine-needle biopsy needles can be useful for obtaining samples that facilitate the diagnosis of SET and for avoiding unwarranted resections. However, FNB needles may be less advantageous for small SET.

Abstract
BACKGROUND Endoscopic resections in the duodenum harbor a significant risk of complications. The full-thickness resection device (FTRD) has shown favorable results concerning efficacy and safety in the resection of colorectal lesions. Data of its use in the duodenum are limited to a single, small case series (n = 4). METHODS Data of all consecutive patients scheduled for endoscopic full-thickness resection (EFTR) of duodenal lesions by FTRD in our institution were collected and analyzed retrospectively. Primary endpoint was technical success. RESULTS Between March 2014 and June 2017 EFTR of a duodenal lesion was planned in a total of 20 patients. Overall technical success was 17/20 (85.0%). Indication for EFTR was: adenomas (n = 13, seven treatment naïve, six pretreated), subepithelial tumors (n = 5) and T1 adenocarcinoma (n = 1). The FTRD could be advanced to the lesion in 19/20 cases (95.0%). R0-resection rate was 12/19 (63.2%). During follow-up after 3 and 12 months there were two recurrent adenomas that were successfully re-resected by FTRD. Minor bleedings occurred at the first postinterventional day in 3/19 (15.8%). There were no major bleedings and perforations. CONCLUSION This study confirmed the feasibility of duodenal EFTR and indicates good efficacy and safety. Larger studies are needed to further investigate this novel technique.

Abstract
Objective Although esophageal granular cell tumors have been reported to present as hypoechoic tumors, we noticed that their echogenicity is similar to that of the submucosal layer. We investigated the sonographic features of esophageal granular cell tumors and the diagnostic accuracy of the features. Methods Seven patients with esophageal granular cell tumors who underwent endoscopic ultrasonography were retrospectively reviewed. Thirteen patients with esophageal leiomyoma were selected as historical control subjects. The brightness of the tumor on ultrasonography images was measured and the echogenicity was standardized according to the echogenicity of the proper muscle and submucosal layers. Ten board-certified endoscopists then independently evaluated the endoscopic pictures of the 20 patients (Test 1), as well as the endoscopic ultrasonography images together with endoscopic pictures of the same patient set (Test 2). Results The standardized echogenicity in granular cell tumors was significantly higher than that in leiomyomas. The diagnostic accuracy of the 10 evaluators using endoscopic pictures alone (Test 1) was 72.0%. The addition of endoscopic ultrasonography images (Test 2) significantly improved the accuracy to 93.0%. Conclusion The echogenicity of granular cell tumors was similar to that of the submucosal layer, and it was significantly higher than that of leiomyomas. Endoscopic ultrasonography images facilitate the accurate identification of esophageal granular cell tumors.

Abstract
Endoscopic full-thickness resection (EFTR) is a "changing-concept" endoscopic resection technique, which safely allows resecting deep submucosal tumors (SMTs) in the gastrointestinal (GI) wall. It's a highly promising endoscopic procedure that allows full-thickness excision of a small piece of the complete GI wall by using only a flexible endoscope. EFTR is a meeting point between surgery and endoscopy and probably the onset of many prospective combined minimally invasive therapeutic techniques that science will explore. In this review, use of the EFTR technique for gastrointestinal SMTs is highlighted, focusing on some technical aspects, indications, contraindications and outcomes.

Abstract
Background/Aims To determine the incidence of regional lymphadenopathy in gastrointestinal (GI) schwannoma and to evaluate the relationship between peritumoral lymphoid cuff and lymphadenopathy. Methods We queried 118 GI tract schwannomas and reviewed radiologic findings, intraoperative findings, and electronic medical records of all cases for enlarged regional lymph nodes. Results Location of tumors included 85 gastric (72%), 11 colonic (9.3%), 7 esophageal (5.9%), 3 pancreatic (2.5%), 1 hepatic (0.8%), and 11 mesenteric (9.3%). The size of the tumors ranged from 0.2 to 11 cm (mean 3.8 cm). Histologically, 70.3% showed a peritumoral lymphoid cuff ranging in thickness from 0.3 to 6 mm (mean 1.6 mm). The peritumoral lymphoid cuff was significantly more frequent in gastric schwannomas (78.8%) followed by colonic (72.7%), esophageal (57.1%) and rare in other locations (p = 0.001). Of the 106 cases for which clinical or radiologic data was available for, 76 cases (71.7%) showed regional lymphadenopathy. The presence of peritumoral lymphoid cuff showed significant correlation with regional lymphadenopathy (p < 0.001) and the size of enlarged lymph nodes (p = 0.002). Conclusions A peritumoral lymphoid cuff is frequently seen in GI tract schwannomas and correlates well with regional lymphadenopathy. However, in a significant subset (29.7%), a lymphoid cuff was not present warranting continued need for caution in the preoperative radiologic and postoperative pathologic diagnoses.

Abstract
Background and Objectives The most accurate technology to detect and diagnose subepithelial tumors (SETs) is the endoscopic ultrasonography (EUS) combined with puncture techniques, such as the endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) or the endoscopic ultrasonography-guided fine-needle biopsy. Going further in the improvement of the results of tumor samples obtained endoscopically to diagnose the SETs, the canalization technique guided by miniprobes (MPs) to obtain biopsies of SET could be an alternative to EUS-FNA. The objective of this study is to analyze the results of samples obtained by this procedure. Materials and Methods A multicenter, retrospective study of a review of a database of 32 consecutive patients with a SET in the digestive tract, from 2000 to 2015 was conducted. All patients underwent EUS-performed by MP, to define the size, internal echostructure, and layer of origin of tumor. Once the echostructure was defined, it proceeded to the canalization technique to arrive to the tumor tissue. Results The average diameter of SETs in this series (32 patients) was about 21.6±11 mm (range: 5-41 mm). The diagnostic accuracy was 28/32, 87.50% (Confidence interval 95%: 76.04%-98.99%), and there were no major complications. All procedures were performed on outpatients, none of which required additional hospitalization. The 50% of patients were operated or endoscopically resected and in all cases, the previous pathological diagnosis was confirmed. Conclusions This is a feasible, safe, and effective procedure that allows to access to inside of SET to obtain deep biopsies. Tumor samples obtained by deep biopsy, with prior performing of the canalization technique guided by MP, were sufficient for histopathological and immunohistochemical diagnosis and similar to those obtained with other known methods (FNA Trucut, ProCore®, etc.). However, more prospective comparative studies with a larger number of patients and different specialists carrying out the procedure to reach a higher statistical significance are necessary.

Abstract
Background: Ectopic pancreas (EP) belongs to the most frequent subepithelial lesions (SELs) of the upper gastrointestinal (GI) tract. In the majority of cases, it is detected incidentally. Differential diagnosis from mesenchymal subepithelial tumors may be difficult. Methods: Among 24,308 endosonographic examinations and interventions, which were prospectively enrolled in the database of the German Endoscopic Ultrasound (EUS) Registry from January 2009 to August 2013, 575 were performed for suspected SELs of the upper GI tract. Sixty three cases of EP of the upper GI tract (stomach, n = 53; duodenum, n = 10; esophagus, n = 0) were extracted and retrospectively reviewed. Results: In 65.1% of cases, radial echoendoscopes or radial miniprobes were used for examination. Nearly 84% of EP was found in the stomach, 16% in the duodenum, none in the esophagus. In 88.9% of cases, the EUS examination discerned the layer of origin. In 59% of cases EP was described as a heterogeneous, in 28.6% as a homogeneous-hypoechoic and in 7.9% as a homogeneous-echogenic subepithelial mass lesion. Mean diameter was 13.0 mm × 8.1 mm, the mean ratio between long and short axis diameter was 1.75. EUS-guided fine needle aspiration (EUS-FNA) was used to accomplish cytological or histological diagnosis in only 6.3% of cases. Conclusions: EP accounts for 11% of all EUS examinations performed for subepithelial lesions of the upper GI tract and prospectively enrolled in the German EUS registry. Rather than being an eyecatcher, EP is a chameleon with numerous differential diagnoses. In selected cases, EUS-FNA may help clarifying the diagnosis.

Abstract
Catheter probe endoscopic ultrasonography (C-EUS) by ultrasonographic jelly-filled method has been used to evaluate esophageal subepithelial tumors (SETs). Ultrasonographic jelly is safe on the skin, but its internal safety has not been demonstrated. The jelly stored at room temperature is easily injected into the esophagus through the instrument channel of the endoscope. However, using jelly stored at room temperature remains problematic because the jelly is drained rapidly. We used cold lubricating jelly and an intravenous extension tube to resolve these problems. In this study, we evaluated the safety and efficacy of cold lubricating jelly-filled method. The medical records of patients who underwent C-EUS by using water or cold lubricating jelly-filled method for esophageal SETs from March 2013 to September 2016 in Gangneung Asan hospital were reviewed. Clinical characteristics and EUS findings were evaluated retrospectively. Image quality and procedure time between water and cold lubricating jelly-filled method were compared retrospectively. This study included 138 patients (74 males, 64 females) with esophageal SET with a mean age of 57.1 ± 11.1 years. Thirty-four patients had lesions in the upper esophagus, 58 patients had lesions in the middle esophagus, and 46 patients had lesions in the lower esophagus. The EUS diagnoses were leiomyoma (82.6%), hemangioma (4.3%), extrinsic compressive lesion (3.6%), granulosa cell tumor (2.9%), ectopic calcification (1.4%), cyst (1.4%), lipoma (0.7%), varix (0.7%), and inconclusive lesion (2.2%). The mean image score in the cold lubricating jelly filled-method group was higher than that in the water-filled method group (3.2 ± 0.7 vs. 2.8 ± 0.7, P = 0.002). The procedure time in the cold lubricating jelly filled-method group was shorter than that in the water-filled method group (10 minutes 27 seconds ± 4 minutes 22 seconds versus 13 minutes 20 seconds ± 6 minutes 20 seconds, P = 0.045). No procedure-related complication was observed. C-EUS using the cold lubricating jelly-filled method seems to provide better image quality and shorter procedure time compared with C-EUS using the water-filled method.

Abstract
OBJECTIVE Acquiring adequate tissue for immunohistochemical (IHC) analysis is important in the differential diagnosis of subepithelial tumors (SETs). In this study, we aimed to compare the diagnostic yield based on IHC analysis between endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and EUS-guided fine needle biopsy (EUS-FNB) after on-site cytological evaluation for cellularity in gastric SETs. METHODS In 22 patients with gastric SETs, EUS-guided tissue sampling was performed on the same SET in a randomized sequence, with EUS-FNA followed by EUS-FNB, or vice versa. After on-site cytological evaluation for cellularity, the cytological and histological examinations were performed. RESULTS There was a significant difference in the median number of needle passes to obtain adequate cellularity in the on-site cytological evaluation (2.0 for EUS-FNA vs 1.0 for EUS-FNB, P = 0.008). The proportion of adequate cellularity on the first needle pass was significantly higher in the EUS-FNB than in the EUS-FNA group (68.2% vs 31.8%, P = 0.034). However, diagnosis based on IHC examination was established in 15 (68.2%) and 18 (81.8%) cases by EUS-FNA and EUS-FNB, respectively (P = 0.488). CONCLUSIONS EUS-FNB decreases the number of needle passes to obtain adequate cellularity and yields a higher proportion of adequate cellularity during the first needle pass compared with EUS-FNA in gastric SETs. However, there was no significant difference in diagnostic yield with IHC stain between the two procedures after on-site cytological evaluation for adequate cellularity.

Abstract
Research in endoscopic ultrasound (EUS) is alive and kicking! This paper will present recent interesting developments in EUS based on research presented at the Digestive Disease Week (DDW) held in Chicago in 2014. Endosonographers are looking at various techniques to improve yield of fine needle aspiration and core biopsies, assess circulating tumor cells, apply EUS for personalized medicine and develop devices to ensure the adequacy of sampling. EUS may open new vistas in understanding of neurogastroenterology and gastrointestinal motility disorders as discussed in this paper. EUS guided drainage of pancreatic fluid collections, bile duct and gallbladder is feasible, and many randomized trials are being done to compare different techniques. EUS guided delivery of fiducials, drugs, coils or chemo loaded beads in possible. EUS has come off age, has matured and is here to stay! The DDW in 2014 in Chicago was a very active year for EUS. There were numerous papers on different aspects of EUS, some perfecting and improving old techniques, others dealing with randomized trials and many with novel concepts. In this paper, I will highlight some of the papers that were presented. It is not possible to discuss all the abstracts in detail. I have, therefore, chosen selected papers in different aspects of EUS to give the readers a flavor of the kind of research that was presented at DDW.
