Objective: To study the therapeutic effect of endoscopic submucosal dissection and mucosal resection on gastric neuroendocrine tumor. Methods: A hundred patients with gastric neuroendocrine tumor that were treated in the Affiliated Hospital of Chifeng University from January 2016 to May 2021 were randomly selected for this research. They were divided into two groups, which were the control group (endoscopic mucosal resection) and the study group (endoscopic submucosal dissection), by the digital table method. The curative effects of the two groups were observed and compared. Results: Before operation, there were no significant differences in serum CgA, TNF-?, and IL-6 between the two groups, p > 0.05. After surgical treatment, the operation time and hospital stay of the patients in the study group were shorter than those in the control group, the amount of surgical bleeding was also less compared to the control group, and the complete tumor resection rate was higher than that in the control group (p < 0.05); the levels of IL-6 and CgA of the study group were lower than those in the control group, while the levels of TNF-? were higher than those of the control group, p < 0.05; the postoperative complication rate of the study group was lower than that of the reference group (p < 0.05). Conclusion: Endoscopic submucosal dissection is more effective for gastric neuroendocrine tumors. The resection rate of the tumor is high, and the operation risk is low.

Abstract Background and study aims Several previous reports indicate that endoscopic injection of triamcinolone acetonide (TA) after widespread endoscopic submucosal dissection (ESD) is effective for preventing esophageal stricture. We investigated the efficacy of injecting TA in two sessions for preventing stricture formation post-ESD. Patients and methods Sixty-six consecutive patients with widespread mucosal defects that affected more than three-fourths of the circumference of the esophagus were included. The study group (n = 40) received TA injections over two sessions: immediately after and 14 days after ESD. The control group (n = 26) did not receive a TA injection. This study was performed retrospectively against historical controls. The primary endpoint of this study was frequency of stricture after TA injection. The secondary endpoint was number of required endoscopic balloon dilations (EBDs) after TA injection. Results The post-ESD stricture rate among patients who had subcircumferential mucosal defects was 45.7 % in the study group (16/35 patients), which was significantly lower than the rate of 73.9 % in the control group (17/23 patients; P = 0.031). The number of EBD procedures required was significantly lower in the study group (median 0, range 0 – 7) than in the control group (median 4, range 0 – 20; P < 0.001). There was no significant difference between the study and control groups among the patients who had full circumferential mucosal defects. Conclusion This study showed that performing two sessions of TA injection is an effective and safe treatment for prevention of esophageal stricture following subcircumferential ESD.

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 &lt; 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 &lt; 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 &lt; 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.

Submucosal Dissection

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.

Abstract Background and study aims Sessile serrated lesions (SSL) are major precursor lesions of serrated pathway cancers, and appropriate treatment may prevent interval colorectal cancer. Studies have reported the outcomes of endoscopic mucosal resection (EMR) for SSL; however, there are insufficient reports on endoscopic submucosal dissection (ESD). We examined the characteristics and outcomes of SSL and compared them to those of non-SSL in ESD. Patients and methods We reviewed 370 consecutive cases in 322 patients who underwent colorectal ESD between January 2016 and March 2020 at our hospital. There were 267 0-IIa lesions that were stratified into 41 SSL and 226 non-SSL (intramucosal cancer, adenoma) cases. We used propensity matching to adjust for the variances in the factors affecting treatment between the SSL and non-SSL groups. Results In the baseline cases, young women and proximal colon tumor location were significantly more common in the SSL group. There were no statistically significant differences between the SSL and non-SSL groups in terms of en bloc resection rate (97.6 % vs. 99.6 %; P = 0.28), R0 resection rate (92.7 % vs. 93.4 %; P = 0.74), perforation (0 % vs. 0.9 %; P > 0.99), and postoperative bleeding (2.4 % vs. 1.8 %; P = 0.56). Thirty-eight pairs were matched using propensity score, and the median dissection speed (12 vs. 7.7 cm2/h; P = 0.0095) was significantly faster in the SSL than in the non-SSL group. Conclusions ESD for SSL was safely performed, and SSL was smoother to remove than non-SSL. ESD might be an acceptable endoscopic treatment option for SSL.

Gastrointestinal Lesions

<b><i>Introduction:</i></b> Endoscopic submucosal dissection (ESD) is a well-established endoscopic technique for the treatment of gastrointestinal lesions. Colorectal ESD outcomes are less reported in the Western literature, and Portuguese data are still very scarce. Our aim was to describe our experience on colorectal ESD regarding its outcomes and safety profile. <b><i>Methods:</i></b> We conducted a retrospective evaluation of recorded data on ESDs performed between 2015 and 2020. Only ESDs performed on epithelial neoplastic lesions were selected for further analysis. <b><i>Results:</i></b> Of a total of 167 colorectal ESDs, 153 were included. Technical success was achieved in 147 procedures (96%). The lesions were located in the colon (<i>n</i> = 24) and rectum (<i>n</i> = 123). The en bloc resection rate was 92% and 97%, the R0 resection rate was 83% and 82%, and the curative resection rate was 79% and 78% for the colon and the rectum, respectively. The need for a hybrid technique was the only risk factor for piecemeal or R1 resection. We report a perforation rate of 3.4% and a 4.1% rate of delayed bleeding; all the adverse events were manageable endoscopically, without the need of blood transfusions or surgery. Most of the lesions were laterally spreading tumours of the granular mixed type (70%), and 20% of the lesions were malignant (12% submucosal and 8% intramucosal cancer). <b><i>Conclusion:</i></b> Our series on colorectal ESD reports a very good efficacy and safety profile. This technique can be applied by endoscopists experienced in ESD.
