Clinical Outcomes of Endoscopic Submucosal Tunnel Dissection Vs Endoscopic Submucosal Dissection in Gastric Lesions: a Systematic Review and Meta-analysis

Abstract Background and objectives: Many studies have verified that endoscopic submucosal dissection (ESD) has prominent advantages in en bloc resection and low recurrence rate. However, ESD also has technical difficulty for some large-area gastric lesions. Endoscopic submucosal tunneling dissection (ESTD) combined the tunnel technique with the traditional ESD technique for treating gastrointestinal mucosal lesions under tunnel endoscopy. This technique has been gradually applied to the treatment of large-scale early cancer and precancerous lesions, and has achieved good results. Yet no meta-analysis has been published, so we performed this study to determine the efficacy and safety of ESTD vs ESD in gastric lesions through clinical outcomes.Methods: We performed the literature search in PubMed, Cochrane Library, Web of Science, Embase, Wanfang, and CNKI dating up to February 9, 2021. Studies comparing the clinical outcomes of ESTD and ESD in gastric lesions were enrolled. The Newcastle-Ottawa Quality Assessment Scale was used to evaluate the quality of these studies. Results: Four articles were included that involved a total of 920 patients (187 from the ESTD group and 733 from ESD group). ESTD has higher en bloc resection and R0 resection rate, faster dissection speed, and lower complication rate. The curative resection rate and recurrence rate of ESTD group is comparable with ESD group.Conclusions: ESTD technique is an effective and safe treatment procedure in gastric lesions, and may be prior to ESD for large gastric lesions.

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 Endoscopic submucosal dissection (ESD) has been accepted as a standard treatment for early gastric cardiac cancer (EGCC). Here, we investigate the clinical outcomes of the EGCC patients who underwent ESD in different indications. Methods From January 2011 to October 2019, we enrolled 502 EGCC lesions from 495 patients which were resected by ESD at our center. We retrospectively analyzed the short-term and long-term clinical outcomes among different indication groups. Results The number of the patients in the absolute indication (AI), expanded indication (EI) and beyond the expanded indication (BEI) groups was 265, 137 and 93, respectively. The en bloc resection rate was 100%, 100% and 98.9% (P = 0.185). The complete resection rate was 99.3%, 98.5% and 74.5%, respectively (P < 0.001). During a median follow-up of 48.1 months, the lymph node metastasis rate was 0%, 0% and 2.3% (P < 0.001). The distant metastasis rate was 0.4%, 0% and 2.3% (P = 0.150). The five-year disease-specific survival rate in the BEI group was 96.6% (P = 0.016), compared to 99.6% in the AI group and 100% in the EI group. Conclusion The efficacy for ESD patients in EI group was almost equal to the AI group. Patients in the BEI group showed generally favorable clinical outcomes and needed to be carefully checked after ESD. ESD may be an optional treatment for patients unsuitable for gastrectomy.

Background and Aim. The clinical outcomes of endoscopic submucosal dissection (ESD) for gastric tube cancer (GTC) after esophagectomy remain unclear. The aim of this study was to evaluate the clinical outcomes and safety of ESD for GTC. Patients and Methods. Twenty GTC lesions in 18 consecutive patients who underwent ESD between February 2008 and June 2018 were included in this retrospective study. The endpoints were the treatment outcomes of ESD (i.e., en bloc resection rate, complete en bloc resection rate, and curative resection rate), the adverse events following ESD, and the long-term outcomes. Results. The en bloc resection rate was 100%, while the complete en bloc resection rate and curative resection rate were 80% each. Adverse events were observed in 16.7% (3/18) of patients: one postoperative bleeding, 1 intraoperative perforation that required emergency surgery, and 1 pyothorax that required chest drainage. The 1-, 3-, and 5-year overall survival rates were 100%, 70.9%, and 70.9%, respectively. Although local recurrence was detected in 1 case of noncurative resection, no GTC- or ESD-related deaths were observed. Conclusion. ESD for GTC was feasible and acceptable to enable en bloc resection and to prevent cancer death. However, ESD for GTC should be performed more carefully than common gastric ESD because serious adverse events specific to the gastric tube may occur.

Abstract Background Hybrid endoscopic submucosal dissection (ESD) is increasingly utilized to overcome the complexity of conventional ESD. This systematic review and meta-analysis evaluated the efficacy and safety of hybrid ESD for treatment of colorectal lesions. Methods Search strategies were developed in accordance with PRISMA guidelines. Pooled proportions were calculated with rates estimated using random effects models. Measured outcomes included en bloc resection, procedure-associated complications, recurrence, and need for surgery. Subgroup analyses were performed to compare effectiveness of conventional versus hybrid ESD. Results 16 studies (751 patients) were included with a mean (standard deviation [SD]) lesion size of 27.96 (10.55) mm. En bloc resection rate was 81.63 % (95 % confidence interval [CI] 72.07 – 88.44; I2 = 80.89). Complications, recurrences, and need for surgery occurred in 7.74 % (95 %CI 4.78 – 12.31; I2 = 65.84), 4.52 % (95 %CI 1.40 – 13.65; I2 = 76.81), and 3.64 % (95 %CI 1.76 – 7.37; I2 = 15.52), respectively. Mean procedure duration was 48.83 (22.37) minutes. On subgroup analyses comparing outcomes for conventional (n = 1703) versus hybrid ESD (n = 497), procedure duration was significantly shorter for hybrid ESD (mean difference 18.45 minutes; P = 0.003), with lower complication rates (P = 0.04); however, hybrid ESD had lower en bloc resection rates (P < 0.001). There was no difference in rates of recurrence or surgery (P > 0.05). Conclusion While hybrid ESD was safe and effective for removal of colorectal lesions, with shorter procedure duration, fewer complications, and no difference in recurrence versus conventional ESD, hybrid ESD was associated with a lower en bloc resection rate.

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

Introduction: 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. Methods: 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. Results: 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 (n = 24) and rectum (n = 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). Conclusion: Our series on colorectal ESD reports a very good efficacy and safety profile. This technique can be applied by endoscopists experienced in ESD.
