Endoscopic full‑thickness resection with clip‑ and snare‑assisted traction for gastric submucosal tumours in the fundus: A single‑centre case series. Oncol Lett 2023; 25:151. [PMID: 36936023 PMCID: PMC10018235 DOI: 10.3892/ol.2023.13737] [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: 10/24/2022] [Accepted: 02/15/2023] [Indexed: 03/06/2023] Open
Abstract
Exposed endoscopic full-thickness resection (Eo-EFTR) has been recognized as a feasible therapy for gastrointestinal submucosal tumours (SMTs) originating deep in the muscularis propria layer; however, Eo-EFTR is difficult to perform in a retroflexed fashion in the gastric fundus. As a supportive technique, clip- and snare-assisted traction may help expose the surgical field and shorten the operation time in endoscopic resection of difficult regions. However, the application of clip- and snare-assisted traction in Eo-EFTR of SMTs in the gastric fundus is limited. Between April 2018 and December 2021, Eo-EFTR with clip- and snare-assisted traction was performed in 20 patients with SMTs in the gastric fundus at The First Affiliated Hospital of Soochow University. The relevant clinical data were collected retrospectively for all of the patients and analysed. All 20 patients underwent Eo-EFTR successfully without conversion to open surgery or severe adverse events. The en bloc resection rate and R0 resection rate were both 100%. Two patients had abdominal pain and fever after the operation, and five patients had fever, which recovered with medical therapy. No complications, such as delayed bleeding or delayed perforation, were observed. The postoperative pathology indicated that 19 cases were gastrointestinal stromal tumours and one case was leiomyoma. During the follow-up, no residual tumour, local recurrence or distant metastasis was detected by endoscopy or abdominal computed tomography. In conclusion, Eo-EFTR with clip- and snare-assisted traction appears to be a relatively safe and effective treatment for gastric SMTs in the fundus. However, prospective studies on a larger sample size are required to verify the effect of the clip- and snare-assisted traction in Eo-EFTR.

Abstract
The risk-benefit profile of submucosal endoscopic procedures is generally favorable but there exist unique considerations regarding the recognition, treatment, and prevention of submucosal endoscopic complications. Bleeding during the procedure can be managed with knife electrocautery, tamponade by injection of additional submucosal agent, or hemostatic forceps, depending on the location and degree of bleeding. Delayed bleeding should be managed with repeat endoscopy. Potential means to reduce the risk of delayed bleeding include anticipatory coagulation of visible vessels in the dissection ulcer base, applied hemostatic chemicals, snares, clips, and sheets of cultured cells.

Abstract
BACKGROUND AND AIMS Effective traction is an important prerequisite for successful endoscopic submucosal dissection (ESD). The combined orthodontic rubber band (ORB) and clip method was effective in colorectal cancer ESD. To date, the method was not reported in gastric ESD. This study aimed to investigate its efficacy and safety for gastric neoplasms ESD. METHODS We retrospectively analyzed data of 118 patients with gastric neoplasms treated by ESD from November 2020 to April 2022, 43 by ORB-ESD and 75 by the conventional ESD. The primary outcome measure was the ESD procedure time. Clinical data on efficacy and safety were also collected and analyzed. Propensity score matching (PSM) matched the patients in both groups. RESULTS PSM successfully matched 31 pairs of patients. The ORB-ESD operation time was shorter (median [interquartile range], 35 [30-48] vs. 49 [40-70] min, P < 0.001) and dissection speed was higher (median [interquartile range], 22.6 [14.4-29.3] vs. 13.5 [9.6-17.9] mm2/min, P < 0.001) than in the conventional ESD. The groups were similar in muscular injury rate, frequency and time of use of thermal hemostatic forceps, postoperative adverse events, en bloc resection, and R0 resection rate (P > 0.05). CONCLUSIONS Compared to the conventional ESD, ORB-ESD significantly reduced the procedure time and increased the dissection speed, proving beneficial to gastric ESD.

Abstract
BACKGROUND AND AIMS Simultaneous endoscopic submucosal dissection (ESD) is occasionally used in synchronous multiple gastric neoplastic lesions (SMGL). Therefore, we aim to evaluate the safety and efficacy of simultaneous ESD for SMGL compared with ESD for single lesions. METHODS A total of 1058 patients who received ESD from November 2006 to September 2019 were retrospectively evaluated in this study, including 997 single gastric epithelial lesions treated by single ESD (unifocal group) and 125 SMGL from 61 patients treated by simultaneous ESD (multifocal group). RESULTS The mean procedure time was 49.2 ± 41.30 min and 89.5 ± 66.33 min in unifocal group and multifocal group, respectively (p < 0.001). There was no significant difference in postoperative stenosis rate (1.0% vs. 0.0%, p = 1.000), intraoperative bleeding (endoscopic resection bleeding-c3 grade) rate (0.5% vs. 1.6%, p = 0.696), postoperative bleeding rate (1.3% vs. 0.0%, p = 0.461), and perforation rate (0.9% vs. 1.6%, p = 0.449) between the two groups. In addition, en block resection rate (p = 0.825), complete resection rate (p = 0.856) and curative resection rate (p = 0.709) were comparable between the two groups. During the follow-up, the local recurrence rate per patient: p = 0.363; per lesion: p = 0.235) was not significantly different between the two groups, however, the cumulative incidence of metachronous lesions after treatment was significantly higher in the multifocal group than the other group (10.0% vs. 3.2%, p = 0.004). CONCLUSIONS Simultaneous ESD is safe and effective in the treatment of SMGL. However, separate ESD is recommended for SMGL with longer procedure time. Besides, the metachronous gastric neoplastic lesions should be paid attention to during follow-up.

Abstract
Endoscopic resection is first-line therapy in the management of superficial neoplasms throughout the gastrointestinal tract, as well as an increasingly viable therapeutic alternative in the resection of selected small deep lesions throughout the upper and lower gastrointestinal tract. The mainstay of therapy has traditionally been endoscopic snare polypectomy and endoscopic mucosal resection. However, recent innovative advancements in therapeutic endoscopy have provided for the ability to resect large superficial lesions and selected subepithelial lesions in en bloc and margin-negative fashion. In this review, we discuss the current state of the art in advanced endoscopic resection techniques including endoscopic submucosal dissection and endoscopic full-thickness resection.

Recent approach for preventing complications in upper gastrointestinal endoscopic submucosal dissection. DEN OPEN 2022; 2:e60.

Abstract
Although endoscopic submucosal dissection (ESD) is a minimally invasive treatment method for upper gastrointestinal (GI) tumors, patients undergoing upper GI ESD sometimes fall into a serious condition from complications. Thus, it is important to fully understand how to prevent complications when performing upper GI ESD. One of the major complications in esophageal and gastric ESD is intraoperative perforation. To prevent this complication, blind dissection should be avoided. Traction-assisted ESD is a useful technique for maintaining good endoscopic view. This method was proven to reduce the incidence of intraoperative perforation, which would become a standard technique in esophageal and gastric ESD. In gastric ESD, delayed bleeding is the most common complication. Recently, a novel prediction model (BEST-J score) consisting of 10 factors with four risk categories for delayed bleeding in gastric ESD was established, and a free mobile application is now available. For reducing delayed bleeding in gastric ESD, vonoprazan ≥20 mg/day is the sole reliable method in the current status. Duodenal ESD is still challenging with a much higher frequency of complications, such as perforation and delayed bleeding, than ESD in other organs. However, with the development of improved devices and techniques, the frequency of complications in duodenal ESD has been decreasing. To prevent intraoperative perforation, some ESD techniques, such as using the distal tips of the Clutch Cutter, were developed. An endoscopic mucosal defect closure technique would be mandatory for preventing delayed complications. However, several unresolved issues, including standardization of duodenal ESD, remain and further studies are demanded.

Abstract
BACKGROUND Endoscopic resection bleeding (ERB) classification was proposed by the authors' team to evaluate the severity of intraoperative bleeding (IB) during endoscopic submucosal dissection (ESD). This study aimed to evaluate the application of ERB classification and to analyze the risk factors of major IB (MIB) and postoperative bleeding (PB) associated with ESD for gastric neoplastic lesions. METHODS We retrospectively enrolled a total of 1334 patients who underwent ESD between November 2006 and September 2019 at The First Medical Center of Chinese People's Liberation Army General Hospital. All patients were divided into the non-MIB group (including ERB-0, ERB-controlled 1 [ERB-c1], and ERB-c2) and the MIB group (including ERB-c3 and ERB-uncontrolled [ERB-unc]) according to the ERB classification. Risk factors of major MIB and risk factors of PB were analyzed using a logistic regression model. RESULTS Among the 1334 patients, 773 (57.95%) had ERB-0, 477 (35.76%) had ERB-c1, 77 (5.77%) had ERB-c2, 7 (0.52%) had ERB-c3, and no patients had ERB-unc. The rate of PB in patients with IB classifications of ERB-0, ERB-c1, ERB-c2, and ERB-c3 were 2.20% (17/773), 3.35% (16/477), 9.09% (7/77), and 2/7, respectively. In multivariate analysis, proximal location (odds ratio [OR]: 1.488; 95% confidence interval [CI]: 1.045-3.645; P = 0.047) was the only significant risk factor of MIB. Chronic kidney disease (CKD) (OR: 7.844; 95% CI: 1.637-37.583; P = 0.010) and MIB (ERB-c3) (OR: 13.932; 95% CI: 2.585-74.794; P = 0.002) were independent risk factors of PB. CONCLUSIONS Proximal location of lesions was a significant risk factor of MIB. Additionally, CKD and MIB (ERB-c3) were independent risk factors of PB. More attention should be paid to these high-risk patients for MIB and PB.

Abstract
OBJECTIVE To study computed tomography (CT) imaging characteristics of bladder tumors, to explore the value of CT in tumor diagnosis, and to identify the relevant factors of CT missed diagnosis so that medical staff can be more accurate in the diagnosis of bladder tumors. METHODS To retrospectively analyze the CT manifestations of 153 bladder tumor cases confirmed by paraffin pathology in our hospital and to study the difference between the benign and CT imaging features. CT indicators mainly include the number, location, morphology, calcification, bladder wall smoothness, CT value, degree of enhancement, and invasion of surrounding tissues and organs. Then, we retrospectively analyze 17 cases of CT missed diagnosis of bladder tumors, analyze related factors, and discuss the role of CT in the diagnosis of bladder tumors. RESULTS This study has shown that with the help of CT images, the diagnosis rate of bladder tumors has been greatly improved. Of the 153 patients studied, noninvasive urothelial carcinoma accounted for 18.95% of all benign and malignant bladder tumors, invasive urothelial carcinoma accounted for 67.93%, prostatic metastatic carcinoma and inflammatory myofibroblastoma accounted for 8.47%, pheochromocytoma accounted for 1.31%, inverted papilloma accounted for 1.31%, tubular choriocarcinoma accounted for 0.63%, and endocystitis accounted for 1.31%. In addition, the blood supply level, CT index bladder wall smoothness, and CT value are also statistically significant (P < 0.05). CONCLUSIONS CT is of high value in the diagnosis of bladder tumors, and benign and malignant bladder tumors have CT and CT imaging features. The size of bladder tumors is related to the missed diagnosis rate of CT. The application of CT examination technology can improve the accuracy of diagnosis of bladder tumors.

Abstract
This article explores advances in endoscopic neoplasia detection with supporting clinical evidence and future aims. The ability to detect early gastric neoplastic lesions amenable to curative endoscopic submucosal dissection provides the opportunity to decrease gastric cancer mortality rates. Newer imaging techniques offer enhanced views of mucosal and microvascular structures and show promise in differentiating benign from malignant lesions and improving targeted biopsies. Conventional chromoendoscopy is well studied and validated. Narrow band imaging demonstrates superiority over magnified white light. Autofluorescence imaging, i-scan, flexible spectral imaging color enhancement, and bright image enhanced endoscopy show promise but insufficient evidence to change current clinical practice.

Abstract
BACKGROUND AND AIMS Several traction methods have sought to overcome the technical difficulties of endoscopic submucosal dissection (ESD). However, traction direction has remained limited in most of these methods, with lack of clarity about the optimal method and traction direction for gastric ESD. A spring-and-loop with clip (SLC) has been developed as a multidirectional traction device. Here, we investigated whether SLC traction-assisted ESD (SLC-ESD) improved procedure-related outcomes compared with conventional ESD (C-ESD) among patients with superficial gastric neoplasms. METHODS This single-center randomized controlled trial included patients with superficial gastric neoplasms undergoing SLC-ESD or C-ESD between October 2018 and December 2019. Using the multidirectional traction function, we set traction vertical to the gastric wall for SLC-ESD. The primary outcome was the median procedure time for gastric ESD. RESULTS The SLC-ESD and C-ESD groups comprised 40 patients each, and all the enrolled patients underwent the assigned treatment. The median ESD procedure time was significantly shorter in the SLC-ESD group (29.1 minutes) than in the C-ESD group (52.6 minutes; P = .005). SLC had a mean attachment time of 1.82 minutes. En bloc resection was achieved without perforation in all the patients in both groups. CONCLUSIONS Our findings suggest that SLC-ESD reduces gastric ESD procedure time without increasing the risk of perforation and that the vertical direction to the gastric wall is the appropriate traction direction for gastric ESD.

Efficacy of endoscopic preventive procedures to reduce delayed adverse events after endoscopic resection of superficial nonampullary duodenal epithelial tumors: a meta-analysis of observational comparative trials. Gastrointest Endosc 2021; 93:367-374.e3. [PMID: 32835670 DOI: 10.1016/j.gie.2020.08.017] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 08/19/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Although various procedures have been used to prevent serious adverse events after endoscopic resection of the duodenum, their effectiveness has not been determined. In this study, we conducted a systematic review and meta-analysis to determine whether endoscopic preventive procedures reduce delayed adverse events. METHODS Studies on endoscopic treatment for superficial nonampullary duodenal tumors were selected. We compared the following 2 groups: the closure group, which underwent mucosal sutures and coverage of mucosal defects after resection, and the unclosed group, which did not. The primary outcome was the rate of delayed adverse events, including perforation and bleeding. The pooled risk ratios (RRs) of all outcomes investigated, the 95% confidence intervals (CIs), and P values were calculated. RESULTS A total of 438 patients from 4 studies were included in the meta-analysis. The pooled overall adverse event rates in the closure group and unclosed group were 3.6% and 21.1%, respectively. This rate was significantly lower in the closure group (RR, 0.19; 95% CI, 0.10-0.38; P < .01; I2 = 0%), and the rate of delayed bleeding was significantly lower in the closure group (RR, 0.14; 95% CI, 0.06-0.33; P < .01; I2 = 0%). Regarding delayed perforation, the RR in the closure group was 0.39 (95% CI, 0.12-1.32; P = .13; I2 = 0%). CONCLUSIONS Preventive procedures significantly reduced the risk of delayed adverse events by more than 80%. After endoscopic resection of the duodenum, the implementation of preventive procedures, including mucosal sutures and coverage of mucosal defects, to delay adverse events is strongly recommended.

Abstract
BACKGROUND & AIMS Endoscopic screening for gastric cancer is routine in some countries with high incidence and is associated with reduced gastric cancer-related mortality. Immigrants from countries of high incidence to low incidence of gastric cancer retain their elevated risk, but no screening recommendations have been made for these groups in the United States. We aimed to determine the cost effectiveness of different endoscopic screening strategies for noncardia gastric cancer, compared with no screening, among Chinese, Filipino, Southeast Asian, Vietnamese, Korean, and Japanese Americans. METHODS We generated a decision-analytic Markov model to simulate a cohort of asymptomatic 50-year-old Asian Americans. The cost effectiveness of 2 distinct strategies for endoscopic gastric cancer screening was compared with no screening for each group, stratified by sex. Outcome measures were reported in incremental cost-effectiveness ratios (ICERs), with a willingness-to-pay threshold of $100,000/quality-adjusted life-year (QALY). Extensive sensitivity analyses were performed. RESULTS Compared with performing no endoscopic gastric cancer screening, performing a 1-time upper endoscopy with biopsies, with continued endoscopic surveillance if gastric intestinal metaplasia was identified, was cost effective, whereas performing ongoing biennial endoscopies, even for patients with normal findings from endoscopy and histopathology, was not. The lowest ICERs were observed for Chinese, Japanese, and Korean Americans (all <$73,748/QALY). CONCLUSIONS Endoscopic screening for gastric cancer with ongoing surveillance of gastric preneoplasia is cost effective for Asian Americans ages 50 years or older in the United States. The lowest ICERs were for Chinese, Japanese, and Korean Americans (all <$73,748/QALY).

Frontiers of Robotic Gastroscopy: A Comprehensive Review of Robotic Gastroscopes and Technologies. Cancers (Basel) 2020; 12:cancers12102775. [PMID: 32998213 PMCID: PMC7600666 DOI: 10.3390/cancers12102775] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 09/22/2020] [Accepted: 09/25/2020] [Indexed: 02/06/2023] Open
Abstract
Simple Summary With the rapid advancements of medical technologies and patients’ higher expectations for precision diagnostic and surgical outcomes, gastroscopy has been increasingly adopted for the detection and treatment of pathologies in the upper digestive tract. Correspondingly, robotic gastroscopes with advanced functionalities, e.g., disposable, dextrous and not invasive solutions, have been developed in the last years. This article extensively reviews these novel devices and describes their functionalities and performance. In addition, the implementation of artificial intelligence technology into robotic gastroscopes, combined with remote telehealth endoscopy services, are discussed. The aim of this paper is to provide a clear and comprehensive view of contemporary robotic gastroscopes and ancillary technologies to support medical practitioners in their future clinical practice but also to inspire and drive new engineering developments. Abstract Upper gastrointestinal (UGI) tract pathology is common worldwide. With recent advancements in robotics, innovative diagnostic and treatment devices have been developed and several translational attempts made. This review paper aims to provide a highly pictorial critical review of robotic gastroscopes, so that clinicians and researchers can obtain a swift and comprehensive overview of key technologies and challenges. Therefore, the paper presents robotic gastroscopes, either commercial or at a progressed technology readiness level. Among them, we show tethered and wireless gastroscopes, as well as devices aimed for UGI surgery. The technological features of these instruments, as well as their clinical adoption and performance, are described and compared. Although the existing endoscopic devices have thus far provided substantial improvements in the effectiveness of diagnosis and treatment, there are certain aspects that represent unwavering predicaments of the current gastroenterology practice. A detailed list includes difficulties and risks, such as transmission of communicable diseases (e.g., COVID-19) due to the doctor–patient proximity, unchanged learning curves, variable detection rates, procedure-related adverse events, endoscopists’ and nurses’ burnouts, limited human and/or material resources, and patients’ preferences to choose non-invasive options that further interfere with the successful implementation and adoption of routine screening. The combination of robotics and artificial intelligence, as well as remote telehealth endoscopy services, are also discussed, as viable solutions to improve existing platforms for diagnosis and treatment are emerging.

Kyoto classification in patients who developed multiple gastric carcinomas after Helicobacter pylori eradication. World J Gastrointest Endosc 2020; 12:276-284. [PMID: 32994858 PMCID: PMC7503616 DOI: 10.4253/wjge.v12.i9.276] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 07/29/2020] [Accepted: 08/16/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Endoscopic Kyoto classification predicts gastric cancer risk; however, the score in the patients with primary gastric cancer after Helicobacter pylori (H. pylori) eradication therapy is unknown.
AIM To elucidate the Kyoto classification score in patients with both single gastric cancer and multiple gastric cancers developed after H. pylori eradication.
METHODS The endoscopist recorded the Kyoto classification at the endoscope and the Kyoto classification score at the time of the first diagnosis of gastric cancer after H. pylori eradication. The score was compared between single gastric cancer group and multiple gastric cancers group.
RESULTS The Kyoto score at the time of diagnosis of 45 cases of gastric cancer after H. pylori eradication was 4.0 points in average. The score was 3.8 points in the single gastric cancer group, and 5.1 points in the multiple gastric cancers group. The multiple group had a significantly higher score than the single group (P = 0.016). In the multiple gastric cancers group, all the patients (7/7) had 5 or higher Kyoto score, while in single gastric cancer group, the proportion of patients with a score of 5 or higher was less than half, or 44.7% (17/38).
CONCLUSION Patients diagnosed with gastric cancer after H. pylori eradication tended to have advanced gastritis. In particular, in cases of multiple gastric cancers developed after H. pylori eradication, the endoscopic Kyoto classification score tended to be 5 or higher in patients with an open type atrophic gastritis and the intestinal metaplasia extended to the corpus.

Abstract
BACKGROUND A national endoscopic screening program for gastric cancer was rolled out in Japan in 2015. We used a microsimulation model to estimate the cost-effectiveness of current screening guidelines and alternative screening strategies in Japan. METHODS We developed a microsimulation model that simulated a virtual population corresponding to the Japanese population in risk factor profile and life expectancy. We evaluated 15 endoscopic screening scenarios with various starting ages, stopping ages, and screening intervals. The primary outcomes were quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratio. Cost-effective screening strategies were determined using a willingness-to-pay threshold of $50,000 per QALY gained. One-way sensitivity and probabilistic sensitivity analyses were done to explore model uncertainty. RESULTS Using the threshold of $50,000 per QALY, a triennial screening program for individuals aged 50 to 75 years was the cost-effective strategy, with an incremental cost-effectiveness ratio of $45,665. Compared with no endoscopic screening, this strategy is predicted to prevent 63% of gastric cancer mortality and confer 27.2 QALYs gained per 1000 individuals over a lifetime period. Current screening guidelines were not on the cost-effectiveness efficient frontier. The results were robust on one-way sensitivity analyses and probabilistic sensitivity analysis. CONCLUSIONS This modeling study suggests that the endoscopic screening program in Japan would be cost-effective when implemented between age 50 and 75 years, with the screening repeated every 3 years. These findings underscore the need for further evaluation of the current gastric cancer screening recommendations.

Abstract
Endoscopic submucosal dissection (ESD) is generally used to treat gastric mucosal and submucosal lesions. Nevertheless, ESD is more difficult and complicated to perform than a traditional endoscopic mucosal resection, which can increase the incidence of various complications including hemorrhage, perforation and infection. Hemorrhage is a major post-ESD complication. Prevention and early diagnosis of post-ESD bleeding for gastric lesions are closely associated with the efficacy and safety of the operation. Many studies have reported the risks of and the preventative measures for hemorrhage after gastric ESD, but there remain some issues to be solved. We thus reviewed the risk factors, precautions and treatments for hemorrhage after ESD of gastric lesions.

Abstract
Background and Study Aim Superficial gastrointestinal (GI) neoplasms can be treated with endoscopic mucosal resection (EMR) and/or endoscopic submucosal dissection (ESD). These techniques are widely used in Eastern countries; however, its use in the West is limited. The aim of this study was to evaluate the current implementation of ESD in Western countries. Methods Western endoscopists (n = 279) who published papers related to EMR/ESD between 2005 and 2017 were asked to complete an online survey from December 2017 to February 2018. Results A total of 58 endoscopists (21%) completed the survey. Thirty performed ESD in the esophagus (52%), 45 in the stomach (78%), 36 in the co-lorectum (62%), and 6 in the duodenum (10%). The median total number of lesions ever treated per endoscopist was 190, with a median number per endoscopist in 2016 of 41 (7 [IQR 1-21], 6 [IQR 4-16], and 28 [5-63] in the esophagus, in the stomach, and in the colon and rectum, respectively). En bloc resection rates were 97% in the esophagus, 95% in the stomach, and 84% in the colorectum. Complete resection (R0) was achieved in 88, 91, and 81%, respectively. Curative rates were 69, 70, and 67%, respectively. Major complications (perforation or delayed bleeding) occurred more often in colorectal ESD (12 vs. 6% in the esophagus and 7% in the stomach). In the upper GI tract, the majority of resected lesions were intramucosal adenocarcinoma (59% in the esophagus; 47% in the stomach), while in the colorectum the majority were adenomas (59%). Conclusion ESD seems to be performed by a large number of centers and endoscopists. Our results suggest that ESD is being successfully implemented in Western countries, achieving a good rate of efficacy and safety according to European guidelines.

Abstract
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have been well-established methods of treating upper gastrointestinal neoplasia. The aim of this study was to identify the safety and effectiveness of endoscopic treatment for gastric neoplasia within a 2-day hospital stay.Between 2004 and 2015, a total of 914 patients with gastric neoplasia were treated with EMR or ESD within 2 days of hospitalization. The neoplasia sites, en bloc resection rates, pathology, local residual neoplasia rates, and major complications were evaluated retrospectively.The mean age was 63.4 years old, and 636 (69.6%) patients were male. Adenoma was the most common final diagnosis (60.9%), followed by adenocarcinoma (28.9%). The first follow-up endoscopy was performed 4.9 ± 1.1 months after the procedure, and an average of 4.4 endoscopic examinations were performed for 7.16 years (range, 2.1 to 10.2 years). Additional surgery was performed in 11 (1.2%) cases based on post-procedure pathology results. On follow-up endoscopy, a mean of 5.9 months after the procedure, there were 18 residual neoplasia cases (EMR = 13, ESD = 5). Only 4 (0.4%) patients returned to the emergency unit with delayed bleeding, but all 4 cases were successfully controlled with endoscopic treatment. There were no other complications such as delayed perforation or aspiration pneumonia during the 2 days in hospital.EMR and ESD within only 2 days in hospital showed safe and effective outcomes in terms of managing early gastric neoplasia with low complication and local residual rates.

Abstract
BACKGROUND/AIMS Open resection/laparoscopic resection (LR) is the traditional treatment of gastric submucosal tumor (G-SMT). The endoscopic resection (ER) technology provides good results for G-SMT treatment but lacks sufficient evidence-based evidence. This retrospective study aimed to compare the clinical efficacy of ER [endoscopic submucosal dissection (ESD), endoscopic submucosal excavation (ESE), and endoscopic full-thickness resection (EFR)] and LR [laparoscopic wedge resection (LWR) and laparoscopic subtotal gastrectomy (LSG)] for G-SMT. PATIENTS AND METHODS From January 2013 to January 2017, data of patients with G-SMT with tumor diameter <5 cm were collected from the database of The Affiliated Hospital of Qingdao University and classified based on surgical methods. Demographics, tumor characteristics, surgical outcomes, complications and tumor recurrence were recorded and compared. RESULTS Overall, 275 patients with G-SMT were enrolled: 152 underwent ER (ESD, n = 65; ESE, n = 23; EFR, n = 61) and 123 underwent LR (LWR, n = 93; LSG, n = 30). Age, sex, R0 resection rate, tumor location, type, recurrence and complications were not statistically significant (P > 0.05). The ER group had a significantly higher percentage of intraluminal tumor (94.1% vs 62.4%) and smaller tumor size (1.8 ± 0.8 vs 3.4 ± 1.2 cm) than the LR group. The ER group had less muscular tumors than the LR group (54.6% vs 70.7%). The ER group had no serosal tumor. The ER group had shorter hospitalization time, postoperative hospital stay and diet recovery time. The LR group had shorter operation time, less cost and less blood loss. CONCLUSION ER and LR are safe and effective treatments for SMT. For small intraluminally growing SMT, ER is better than LR.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) is commonly used to treat early-stage digestive cancer because it results in a higher frequency of en-bloc resection and a lower frequency of local recurrence. However, the efficacy and safety of duodenal ESD remain unclear. Therefore, present study is aimed at evaluating clinical outcomes of duodenal ESD. METHODS To evaluate the efficacy and safety of duodenal ESD, electronic databases (MEDLINE, CENTRAL and EMBASE) were searched by two independent reviewers. The authors were contacted for additional information. A meta-analysis was performed to evaluate the efficacy and safety of duodenal ESD. RESULTS A total of 7 studies (203 patients) were included in the quantitative synthesis analysis. The pooled proportions of the frequencies of en-bloc resection, need for surgical intervention, bleeding, intraoperative perforation and delayed perforation were 87%, 4%, 2%, 15% and 2%, respectively. The quality of evidence regarding on surgical intervention outcomes was rated as moderate, whereas that of en-bloc resection was rated as low because of its marked inconsistency. CONCLUSIONS Duodenal ESD produced acceptable outcomes in terms of the en-bloc R0 resection, but the incidence of procedure-related adverse events is high (PROSPERO register, CRD42017057110).

[PMID: 30402144 PMCID: PMC6200958 DOI: 10.3892/etm.2018.6729] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Accepted: 08/02/2018] [Indexed: 12/19/2022] Open
Abstract
The present study aimed to evaluate whether second-look endoscopy (SLE) is able to prevent delayed bleeding after endoscopic submucosal dissection (ESD) of gastric carcinoma and to identify which types of lesion require SLE. ESD of gastric cancer at the early stage was performed on 210 patients between October 2014 and September 2016. Mucosal damage-associated bleeding within 24 h after ESD was considered as delayed bleeding. The association of the characteristics of patients and lesions, as well as surgical factors, with the incidence of bleeding as a measure of outcome was analyzed. A total of 110 patients with melena and/or hematemesis underwent SLE on the second day following gastric ESD. Within the entire cohort (n=210), late delayed bleeding (LDB) was defined as hematemesis or melena occurring following second-look endoscopy. Early delayed bleeding (EDB) was defined as hematemesis or melena occurring from the end of ESD to second-look endoscopy, or as active or possible bleeding at the time of the second-look endoscopy was reported in 17 (8.1%) and 20 patients(9.5%), respectively. The median interval between late delayed bleeding and ESD was one day (range, 1–10 days). The incidence of late delayed bleeding was significantly decreased in the SLE group compared with that in the non-SLE group (4.5 vs. 12%, P=0.028). Multivariate analyses revealed that ulcer, flat gross type, lesion diameter (>2 cm), the resected tumor size of >40 mm and Helicobacter pylori infection were independently associated with late delayed bleeding after ESD, while flat gross type, ulcer, the resected tumor size of >40 mm and artificial ulcer diameter >3 cm were independently associated with early delayed bleeding. Thus, the data of the present study indicates that second-look endoscopy following gastric ESD may be useful in preventing post-ESD delayed bleeding and should be performed on the second day.

Abstract
BACKGROUND & AIMS There are marked racial and ethnic differences in non-cardia gastric cancer prevalence within the United States. Although gastric cancer screening is recommended in some regions of high prevalence, screening is not routinely performed in the United States. Our objective was to determine whether selected non-cardia gastric cancer screening for high-risk races and ethnicities within the United States is cost effective. METHODS We developed a decision analytic Markov model with the base case of a 50-year-old person of non-Hispanic white, non-Hispanic black, Hispanic, or Asian race or ethnicity. The cost effectiveness of a no-screening strategy (current standard) for non-cardia gastric cancer was compared with that of 2 endoscopic screening modalities initiated at the time of screening colonoscopy for colorectal cancer: upper esophagogastroduodenoscopy with biopsy examinations and continued surveillance only if intestinal metaplasia or more severe pathology is identified or esophagogastroduodenoscopy with biopsy examinations continued every 2 years even in the absence of identified pathology. We used prevalence rates, transition probabilities, costs, and quality-adjusted life years (QALYs) from publications and public data sources. Outcome measures were reported in incremental cost-effectiveness ratios, with a willingness-to-pay threshold of $100,000/QALY. RESULTS Compared with biennial and no screening, screening esophagogastroduodenoscopy with continued surveillance only when indicated was cost effective for non-Hispanic blacks ($80,278/QALY), Hispanics ($76,070/QALY), and Asians ($71,451/QALY), but not for non-Hispanic whites ($122,428/QALY). The model was sensitive to intestinal metaplasia prevalence, transition rates from intestinal metaplasia to dysplasia to local and regional cancer, cost of endoscopy, and cost of resection (endoscopic or surgical). CONCLUSIONS Based on a decision analytic Markov model, endoscopic non-cardia gastric cancer screening for high-risk races and ethnicities could be cost effective in the United States.

Abstract
OBJECTIVES Gastric lipomas are rare adipose tumors that constitute less than 1% of gastric tumors. While lipomas generally do not need removal unless symptomatic, endoscopic resection has been proposed as safe for gastric lipomas smaller than 2 cm. Yet, there is no consensus on the optimal treatment method for larger lipomas. We report a case of a giant 7-cm gastric lipoma successfully removed by endoscopic submucosal dissection (ESD) and systematically review the literature for gastric lipomas removed by ESD. METHODS Systematic review was conducted by searching PubMed and Scopus databases, up to 15 February 2018, using combinations of relevant terms. RESULTS We report a 55-year-old male with known gastroesophageal reflux disease and asthma, who sought medical attention due to chronic heartburn and asthma exacerbations. These symptoms were attributed to a large 7 cm × 3 cm gastric lipoma that caused gastric outlet obstruction. The lipoma was safely removed by ESD, allowing quick recovery and alleviation of symptoms. In our review, we identified 20 gastric lipomas treated with ESD, with 15 (75%) being 2 cm or larger. The average size of the lipomas was 4 cm (range: 1.2-9 cm). All lipomas were limited to the submucosa, with 80% of the tumors located in the antrum. Three lipomas were removed by submucosal tunneling. All tumors were successfully removed en bloc and no major complications were reported. CONCLUSION Our findings support the conclusion that ESD may be a safe alternative to conventional surgery for removal of large symptomatic gastric lipomas.

Endoscopic submucosal dissection versus endoscopic mucosal resection for type 0-II superficial gastric lesions larger than 20 mm. Ann Gastroenterol 2018; 31:338-343. [PMID: 29720859 PMCID: PMC5924856 DOI: 10.20524/aog.2018.0237] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2017] [Accepted: 01/12/2018] [Indexed: 12/13/2022] Open
Abstract
Background: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are increasingly used for the treatment of superficial gastrointestinal neoplasia. However, the limits and the indications for each technique are still debated. Our retrospective study aimed to compare these techniques in patients with gastric flat lesions larger than 20 mm without the non-lifting sign. Methods: Between January 2013 and July 2016, a total of 36 patients with early gastric flat lesions larger than 20 mm and without the non-lifting sign were resected by ESD and were followed up by endoscopy. As a control group, 40 EMR cases from our database were matched. En bloc and curative resection were compared between the two groups according to histological assessment, tumor size, recurrence, complication rate, and procedure time. A Kaplan-Meier comparison was performed for both groups with a log-rank test to compare the survival curves; the chi-square test was employed for other parameters. Results: En bloc resection rate and curative resection rate were significantly higher in the ESD group than in the EMR group. Procedure time was significantly longer in the ESD group. No significant differences were found in the recurrence and complication rates, although the former were higher in the EMR group and the latter in the ESD group. Survival curves were similar for both groups. Conclusions: Our retrospective analysis seems to confirm a clear advantage for ESD over EMR in removing early superficial gastric neoplasm. Although ESD has expanded the endoscopic resectability of endoscopic gastric lesions, EMR may still be considered one of the therapeutic options for flat gastric lesions without the non-lifting sign.
