Endoscopic submucosal dissection for rectal neoplasia extending to the dentate line: European experience

Abstract Background and study aims The ideal treatment strategy for rectal neoplasia extending to the dentate line (RNDL) is not well defined. Endoscopic mucosal resection (EMR) and submucosal dissection (ESD) compete with surgical techniques such as transanal endoscopic microsurgery (TEM). Non-Asian data and prospective data on ESD are lacking. The study aim was to evaluate the role of ESD in treatment of RNDL in a Western center. Patients and methods Eighty-six patients with rectal adenomas were included. ESD was performed in 86 rectal adenomas including 24 RNDLs (27.9 %) and 62 lesions distant from the dentate line (72.1 %). Results En bloc resection rate was comparable (91.7 % vs. 93.5 %, P = 0.670) between ESD for RNDL and non-RNDL. R0 resection rate was significantly lower in ESD for RNDL compared to that for non-RNDL (70.8 % vs 88.7 %; P = 0.039), but most non-R0 resection was unclear margin (Rx) and was not obvious positive margin (R1). Accordingly, the recurrence rate after ESD for RNDL (4.5 %) was not statistically different from that for non-RNDL (0 %, P = 0.275) and was lower than that previously reported for EMR. Median procedure time was 127 vs. 110 minutes (P = 0.182). Risk of delayed bleeding (20.8 % vs. 0 %, P = 0.001) and postinterventional pain (33.3 % vs. 14.5 %, P = 0.07) increased in RNDL cases, but they were managed conservatively. Incidence of stricture (4.2 % vs. 1.6 %, P = 0.483) and perforation (0 % vs. 1.6 %, P = 1.000) were similar. Conclusions ESD is a feasible and safe resection technique for RNDLs. A randomized controlled trial comparing ESD to other methods (EMR or transanal surgery) is warranted.

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.

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.

Objectives. Endoscopic submucosal dissection (ESD) for early colorectal neoplasms is regarded as a difficult technique and should commence after receiving the experiences of ESD in the stomach. The implementation of colorectal ESD in countries where early gastric cancer is uncommon might therefore be difficult. The aim is to delineate the feasibility and the learning curve of colorectal ESD performed by a colonoscopist with limited experience of gastric ESD.Methods. The first fifty cases of colorectal ESD, which were performed by a single colonoscopist between July 2010 and April 2013, were enrolled.Results. The mean of age was 64 (±9.204) years with mean size of neoplasm at 33 (±12.63) mm. The mean of procedure time was 70.5 (±48.9) min. The rates ofen blocresection, R0 resection, and curative resection were 86%, 86%, and 82%, respectively. Three patients had immediate perforation, but no patient developed delayed perforation or delayed bleeding.Conclusion. Our result disclosed that it is feasible for colorectal ESD to be performed by a colonoscopist with little experience of gastric ESD through satisfactory training and adequate case selection.

Abstract Background and study aims Surgery is the standard treatment for colon tumors associated with diverticulum. Use of endoscopic submucosal dissection (ESD) to treat such tumors is controversial. The aim of this study was to assess the safety and feasibility of ESD in treating superficial colorectal tumors situated near or involving diverticulum. Patients and methods Consecutive patients from two referral centers who had colorectal tumors near or involving diverticulum treated by ESD were retrospectively studied. Clinicopathological characteristics and clinical outcomes were analyzed. Results Of the 12 patients studied, six had tumors near diverticulum and six had tumors involving diverticulum. The overall en-bloc R0 resection rate, median tumor size and procedure time were 67 %, 26.5 mm (range, 15 – 80 mm) and 110 minutes (range, 50 – 220 minutes), respectively. For tumors near diverticulum group, the en-bloc R0 resection rate was 100 % and no adverse events (AEs) or residual/recurrent tumors were observed. In contrast, for intradiverticular tumors group, the en-bloc R0 resection rate was low at 33 %, and one AE (perforation) was observed. The diverticula were ≥ 6 mm in diameter in the patients with incomplete resection. However, all but one diverticulum was unrecognized before ESD. Two residual tumors were detected at the 12-month surveillance and one required surgery. Conclusions This case series indicates that ESD is safe and feasible for treating colorectal tumors near a diverticulum and might be feasible for tumors involving a diverticulum smaller than 6 mm. Selection for smaller diverticulum size may contribute to higher en-bloc R0 resection rates.

ABSTRACT BACKGROUND: Endoscopic submucosal dissection (ESD) of esophageal superficial neoplasm is associated with a high en bloc R0 resection rate and low recurrence. OBJECTIVE: We aim to compare the performance and clinical outcomes of ESD via ESD after circumferential incision (ESD-C) versus submucosal tunneling (ESD-T). METHODS: Single-center retrospective analysis of all consecutive patients who underwent ESD for superficial esophageal cancer, between 2009 and 2018. ESD-T was defined as the technique of making the mucosal incisions followed by submucosal tunneling in the oral to anal direction. ESD-C consisted of completing a circumferential incision followed by ESD. Main study outcomes included en bloc and R0 resection rates. Secondary outcomes included procedural characteristics, curative resection rate, local recurrence and adverse events. RESULTS: A total of 65 procedures (23 ESD-T and 42 ESD-C) were performed for ESCC (40; 61.5%) and BE-neoplasia (25; 38.5%). There were no statistically significant differences between patients who underwent ESD-T versus ESD-C in en bloc (91.3% vs 100%, P=0.12), R0 (65.2% vs 78.6%, P=0.24), curative resection rates (65.2% vs 73.8%, P=0.47) and mean procedure time (118.7 min with vs 102.4 min, P=0.35). Adverse events for ESD-T and ESD-C were as follows: bleeding (0 versus 2.4%; P=0.53), perforation (4.3% vs 0; P=0.61), esophageal stricture (8.7% versus 9.5%; P=0.31). Local recurrence was encountered in 8.7% after ESD-T and 2.4% after ESD-C (P=0.28) at a mean follow-up of 8 and 2.75 years, respectively (P=0.001). CONCLUSION: ESD-T and ESD-C appear to be equally effective with similar safety profiles for the management of superficial esophageal neoplasms.

Abstract Background: Methods have been developed for preventing delayed bleeding (DB) after gastric endoscopic submucosal dissection (GESD). However, none of the methods can completely prevent DB. We hypothesized that DB could be prevented by a modified search, coagulation, and clipping (MSCC) method for patients at low risk for DB and by combining the use of polyglycolic acid (PGA) sheets and fibrin glue with the MSCC method (PMSCC method) for patients at high risk for DB (antibleeding [ABI] strategy). This study assessed the technical feasibility of this novel strategy.Methods: We investigated 123 lesions in 121 consecutive patients who underwent GESD in Kushiro Rosai Hospital between April 2018 and January 2020. The decision for continuation or cessation of antithrombotic agents was based on the Guidelines for Gastroenterological Endoscopy in Patients Undergoing Antithrombotic Treatment.Results: Oral antithrombotic agents were administered to 28 patients (22.8%). The en bloc R0 resection rate was 98.4%. The MSCC method and the PMSCC method for preventing DB were performed in 114 and 9 lesions, respectively. The median resection time of the MSCC method was 16 min, and the median speed (the resection area divided by the resection time) was 3.6 cm2/10 min. The median resection time of the PMSCC method was 59 min, and the median speed was 1.3 cm2/10 min. The only delayed procedural adverse event was DB in 1 (0.8%) of the 123 lesions.Conclusions: The ABI strategy is feasible for preventing DB both in patients at low risk and in those at high risk for DB after GESD, whereas the PMSCC method may be necessary for reduction of time.

Abstract Background and study aims Resecting large colorectal sessile tumors using endoscopic submucosal dissection (ESD) is challenging because of severe submucosal fibrosis. Previously, we reported that ESD strategy using the pocket-creation method (PCM) is useful for large colorectal sessile tumors, but there are no large studies reporting the effectiveness and safety of the PCM for resection of large colorectal sessile tumors. Patients and methods This was a retrospective review of 90 large colorectal sessile tumors in 89 patients who underwent ESD in our institution. Large colorectal sessile tumors were defined as polypoid lesions 20 mm or more in diameter. We divided them into PCM (n = 40) and conventional method (CM) groups (n = 50). The primary outcome measure was en bloc resection. The inverse-probability-treatment weighting (IPTW) approach was used to adjust for selection bias. Results Both PCM and CM achieved high en bloc resection (100 % vs. 94 %, non-adjusted P = 0.25, IPTW-adjusted P = 0.19) and R0 resection rates (88 % vs. 78 %, non-adjusted P = 0.28, IPTW-adjusted P = 0.27). When PCM was used, the rate of pathologically negative vertical margins was significantly greater than with the CM (IPTW-adjusted P = 0.045). The dissection time was significantly shorter (IPTW-adjusted P = 0.025) and dissection speed faster (IPTW-adjusted P = 0.013) using the PCM than when the CM was used. There was no significant difference in the incidence of adverse events (intraprocedural perforation and delayed bleeding, IPTW-adjusted P = 0.68). Conclusion Although en bloc resection and R0 resection rates were similar, PCM significantly increased the rate of negative vertical margins with rapid dissection for treatment of large colorectal sessile tumors.

Abstract Background and study aims The pocket-creation method (PCM) is a novel strategy for endoscopic submucosal dissection (ESD). The aim of this study is to determine the efficacy of the PCM for colorectal laterally spreading tumors, non-granular type (LST-NG). Patients and methods The records of 126 consecutive patients with colorectal LST-NG who underwent ESD between April 2012 and July 2015 were retrospectively reviewed. Patients were divided into PCM (n = 73) and conventional method (CM) (n = 53) groups. Results The en bloc resection rate in the PCM group was significantly higher than in the CM group (100 % [73/73] vs. 92 % [49/53], P = 0.03). The en bloc resection rate with severe fibrosis was higher in the PCM group than in the CM group (100 % [3/3] vs. 60 % [3/5]). The R0 resection rate for the two groups was not statistically significantly different (93 % [68/73] vs. 91 % [48/53], P = 0.74). The perforation rate in the PCM group was lower than in the CM group although not statistically significantly less (0 % 0/73 vs. 4 % 2/53, P = 0.18). For lesions resected en bloc, dissection speed for the PCM group was significantly faster than for the CM group (median [IQR], 19 [13 –24] vs. 14 [10 – 22] mm2/min, P = 0.03). Conclusion ESD using PCM achieves a reliable and safe resection of colorectal LST-NG.

Abstract Background Endoscopic submucosal dissection (ESD) of residual or locally recurrent (RLR) colonic lesions after previous endoscopic mucosal resection (EMR) is an attractive but challenging technique. The present study aimed to evaluate the effectiveness and safety of ESD with double clip and rubber band traction (DCT-ESD) of RLR colonic lesions. Methods We retrospectively analyzed all consecutive DCT-ESD procedures for RLR colonic lesions (rectum excluded) performed in two French centers. The frequency of en bloc and R0 resections, procedure speed, additional surgery, and complications were evaluated. R0 resection was also used to investigate the learning curve. Results Among the 53 resections, 49 (92.5 %) were performed en bloc and 42 (79.2 %) achieved R0. The median procedure speed was 21 mm2/min. There were four (7.5 %) intraoperative perforations and one delayed bleeding; these were successfully treated endoscopically. There was no salvage surgery for complications. The R0 rate increased from 16/26 (61.5 %) for the first 26 procedures to 26/27 (96.3 %, P = 0.002) for the last 27 procedures. Conclusions DCT-ESD appears to be a safe and effective treatment for RLR colonic lesions after EMR.

Abstract Background and study aims Endoscopic submucosal dissection (ESD) has become the standard treatment for colorectal ESD, but large colorectal tumors remain difficult to remove. We developed a new method, called the palisade technique, by modifying the multiple tunneling technique. In this method, a palisade of submucosal tissue is left beneath the tumor to anchor a dissected specimen, maintaining effective submucosal traction. Patients and methods The study included 11 patients with large colorectal tumors that were over half the circumference of the colorectal lumen which were treated using the palisade technique from August 2017 to October 2019. Overall resection outcomes were assessed. Results All 11 lesions were removed en bloc. The R0 resection rate was 45.6 % because of marginal burning of the specimen, but no local recurrence was found after a median observation period of 31 months. The median submucosal dissection time (SDT) and submucosal dissection speed (SDS) were 170 minutes and 23.1 mm2/min, respectively. One case of post-ESD hemorrhage was successfully managed endoscopically, and two cases of post-colorectal ESD coagulation syndrome were managed conservatively. Conclusion The palisade technique can be an effective and safe technique for treating large colorectal tumors that extend over half the luminal circumference.
