Abstract Background and study aims Mucosal traction as a supportive technique is very useful for endoscopists during endoscopy. For gastric submucosal tumor (SMT), our team explored a method of pulling the SMT with a snare combined with endoclips (PSMT-SE). This study preliminarily explored its feasibility to assist resection of gastric SMT. Patients and methods Operation-related data from patients who underwent gastric SMT removal assisted by PSMT-SE at the Gastrointestinal Endoscopy Center of Guangzhou Nanfang Hospital, China between January 2017 and October 2018 were retrospectively collected: tumor size and location, origin of tumor, total operation time, en bloc resection rate, intraoperative and postoperative complications. Results Forty-two gastric SMTs in 41 patients were included in this study. Fifteen tumors were located in the gastric fundus, 11 in the gastric body, two in the gastric angle, 10 in the gastric antrum, and four in the greater curvature of the gastric fundus and the body junction. Further, 11 tumors originated from the submucosa and 31 originated from the muscularis propria. Endoscopic submucosal dissection and endoscopic full-thickness resection assisted by PSMT-SE were performed to resect 30 and 12 tumors, respectively. PSMT-SE could effectively expose the surgical field. Median diameter of resected tumors was 2.0 (0.7) cm, the total operation time was 45.5 (27.0) min, and the en bloc resection rate was 100 %. No intraoperative or postoperative complications were observed. Conclusion PSMT-SE is a potentially useful method for assisting resection of gastric SMT with tumor traction. Further prospective studies with large sample sizes are warranted.

Abstract OBJECTIVE To explore the efficacy and safety of en bloc resection therapy on posterior fossa tumor in children. METHODS A retrospective analysis was conducted on the clinical data of 94 patients with posterior fossa tumor admitted to Department of Pediatric Neurosurgery, Xinhua Hospital Affiliated to Shanghai Jiaotong University School Of Medicine from January 2018 to December 2019. Among them, 35 cases were treated with traditional resection (control group) and 59 cases with en bloc resection (observation group). We counted the amount of blood loss and the time during tumor resection, We compare the symptoms and signs between the two groups and determine a extent of tumor resection based on microscopic observation and preoperative and postoperative imaging comparison. RESULT: The total tumor resection rate of the observation group (88.1%, 52 / 59) was significantly higher than that of the control group (62.85%, 22 / 35, P < 0.05). The average bleeding volume of 90.8ml in the observation group was significantly smaller than that of the control group (113.3ml, P < 0.05), and the average operation time of 38.6min in the observation group was shorter than that of the control group (57.4min, P < 0.05) only for tumor resection procedure. CONCLUSION En bloc resection technique can effectively accelerate the resection time, reduce intraoperative bleeding and improve the total resection rate of tumors in children’s posterior cranial fossa.

Background: Traditional endoscopic submucosal dissection (ESD) has developed different methods, such as pocket method(P-ESD), traction-assisted method(T-ESD) and Hybrid method(H-ESD). In this meta-analysis, the benefits and drawbacks of different ESD methods were discussed and ranked. Study design: Studies comparing different methods of colorectal ESD were searched by PubMed, Embase, and Cochrane Library databases. The study was conducted for five endpoints: en bloc resection rate, R0 resection rate, operation time, dissection speed, and adverse events rate. Pairwise and network meta-analyses were performed through Rev Man 5.4 and Stata 16.0. The quality of all included studies was assessed using the Cochrane Risk of Bias Tool and Newcastle-Ottawa Scale. Results: Twenty-six studies met the inclusion criteria, including 7 RCTs and 19 non-RCTs, with a total of 3002 patients. The pooled analysis showed that the en bloc resection rate of H-ESD was significantly lower than C-ESD, P-ESD and T-ESD [RR=0.28, 95%CI (0.12, 0.65); RR = 0.11, 95% CI (0.03, 0.44); RR = 8.28, 95% CI (2.50, 27.42)]. Compared with C-ESD, the operation time of H-ESD and T-ESD was significantly shorter [MD=-21.83, 95%CI (-34.76, -8.90); MD=-23.8, 95%CI (-32.55, -15.06)]. Meanwhile, the operation time of T-ESD was also significantly shorter than P-ESD [MD=-18.74, 95%CI (-31.93, -5.54)]. The dissection speed of T-ESD was significantly faster than C-ESD [MD=6.26, 95%CI (2.29, 10.23)]. Conclusion: P-ESD and T-ESD are probably the two best methods of colorectal ESD at present. The advantages of P-ESD are high en bloc resection rate and low incidence of adverse events. The advantages of T-ESD are rapid dissection and short operation time.

Endoscopic submucosal dissection (ESD) is considered superior to endoscopic mucosal resection as an endoscopic resection because of its higher en bloc resection rate, but it is more difficult to perform. As ESD techniques have become more common, and the range of treatment by ESD has expanded, the number of possible complications has also increased, and endoscopists need to manage them. In this report, we will review the management of critical complications, such as hemorrhage, perforation, and stenosis, and we will also discuss educational methods for acquiring and improving ESD skills.

Abstract Background and Aims Ulcerative colitis [UC] patients are at an increased risk of developing colorectal cancer due to chronic inflammation. Endoscopic submucosal dissection [ESD] allows removal of non-invasive neoplastic lesions in the colon, but few data are available on its efficacy in UC patients. Methods Data from consecutive UC patients diagnosed with visible dysplastic lesions in the colon who underwent ESD were evaluated. The en bloc removal, R0 resection and complication rates were calculated. Local recurrence and metachronous lesions during follow-up were identified. A systematic review of the literature with pooled data analysis was performed. Results A total of 53 UC patients [age: 65 years; range 30–74; M/F: 31/22] underwent ESD. The en bloc resection rate was 100%, and the R0 resection rate was 96.2%. Bleeding occurred in seven [13.2%] patients, and perforation in three [5.6%] cases, all treated at endoscopy. No recurrence was observed, but two metachronous lesions were detected. Data from six other studies [three Asian and three European] were available. By pooling data, en bloc resection was successful in 88.4% (95% confidence interval [CI] = 83.5–92) of 216 lesions and in 91.8% [95% CI = 87.3–94.8] of 208 patients. R0 resection was achieved in 169 ESDs, equivalent to a 78.2% [95% CI = 72.3–83.2] rate for lesions and 81.3% [95% CI = 75.4–86] rate for patients. No difference between European and Asian series was noted. Conclusions This pooled data analysis indicated that ESD is a suitable tool for safely and properly removing non-invasive neoplastic lesions on colonic mucosa of selected UC patients.

Background. To systematically evaluate the safety and efficacy of endoscopic submucosal dissection (ESD) versus endoscopic mucosal resection (EMR) for early gastric cancer (EGC). Methods. We searched the databases of PubMed, Web of Science, EMBASE, and the Cochrane Library from January 2000 to April 2017 and included studies that compared the outcomes of ESD with EMR for EGC. These eligible studies that met the inclusion criteria were screened out and were assessed by two independent investigators. Result. In total, 18 retrospective cohort studies were eligible for analysis. Our results indicated that ESD is more beneficial than EMR in increasing the complete resection rate and en bloc resection rate and decreasing the local recurrence rate. However, ESD prolonged operative time and increased incidence of gastric perforation than EMR. No differences were found in postoperative bleeding rate between the two approaches. Conclusion. Compared with EMR, ESD offers higher complete resection rate, higher en bloc resection rate, and lower local recurrence rate but has prolonged operative time and increased incidence of gastric perfusion. There is no statistical difference in the rate of postoperative bleeding between the two groups. However, the above conclusion needs further verification by well-designed, randomized trials with larger samples and long follow-up periods.

Abstract Background We analyzed the efficacy of precutting endoscopic mucosal resection (EMR), which is a method of making a full or partial circumferential mucosal incision around a tumor with a snare tip for en bloc resection. Methods We reviewed cases from 2011 to 2018 in which precutting EMR (n = 167) and standard EMR (n = 557) were performed for lesions of 10 – 30 mm. Precutting EMR was indicated for benign lesions of 20 – 30 mm or lesions of < 20 mm for which standard EMR was difficult. Through propensity score matching of the two groups, the therapeutic outcomes for 35 lesions of ≥ 20 mm and 98 lesions of < 20 mm in each group were analyzed. Results In the two sizes of lesion, there were significant differences between the precutting and standard groups in the en bloc resection rate (≥ 20 mm 88.6 % vs. 48.5 %, P < 0.001; < 20 mm 98.0 % vs. 85.7 %, P = 0.004) and the histological complete resection rate (≥ 20 mm 71.4 % vs. 42.9 %, P = 0.02; < 20 mm 87.8 % vs. 67.3 %, P < 0.001). Conclusion Precutting EMR enabled high en bloc resection rates in cases involving difficult lesions.

Abstract Background Endoscopic resection, including endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFR), was used to resect small gastric submucosal tumors (SMTs). Our team explored a method of tumor traction using a snare combined with endoclips to assist in the resection of SMTs. This study aims to explore the safety and effectiveness of the method. Methods This research performed a propensity-score-matching (PSM) analysis to compare ESD/EFR assisted by a snare combined with endoclips (ESD/EFR with snare traction) with conventional ESD/EFR for the resection of gastric SMTs. Comparisons were made between the two groups, including operative time, en bloc resection rate, perioperative complications, and operation-related costs. Results A total of 253 patients with gastric SMTs resected between January 2012 and March 2019 were included in this study. PSM yielded 51 matched pairs. No significant differences were identified between the two groups in perioperative complications or the costs of disposable endoscopic surgical accessories. However, the ESD/EFR-with-snare-traction group had a shorter median operative time (39 vs 60 min, P = 0.005) and lower rate of en bloc resection (88.2% vs 100%, P = 0.027). Conclusions ESD/EFR with snare traction demonstrated a higher efficiency and en bloc resection rate for gastric SMTs, with no increases in perioperative complications and the costs of endoscopic surgical accessories. Therefore, the method seems an appropriate choice for the resection of gastric SMTs.
