Abstract
BACKGROUND Advanced endoscopic resection techniques are used to treat colorectal neoplasms that are not amenable to conventional colonoscopic resection. Literature regarding the predictors of the outcomes of advanced endoscopic resections, especially from a colorectal surgical unit, is limited. OBJECTIVE To determine the predictors of short-term and long-term outcomes after advanced endoscopic resections. DESIGN Retrospective case series. SETTINGS Tertiary care center. PATIENTS Patients who underwent advanced endoscopic resections for colorectal neoplasms from November 2011 to August 2022. INTERVENTIONS Endoscopic mucosal resection, endoscopic submucosal dissection, hybrid endoscopic submucosal dissection, and combined endoscopic laparoscopic surgery. MAIN OUTCOME MEASURES Predictors of en bloc and R0 resection, bleeding, and perforation were determined using univariable and multivariable logistic regression models. Cox regression models were used to determine the predictors of tumor recurrence. RESULTS A total of 1213 colorectal lesions from 1047 patients were resected (median age 66 [interquartile range, 58-72] years, 484 women [46.2%], median BMI 28.6 [interquartile range, 24.8-32.6]). Most neoplasms were in the proximal colon (898; 74%). The median lesion size was 30 (interquartile range, 20-40; range, 0-120) mm. Nine hundred eleven lesions (75.1%) underwent previous interventions. The most common Paris and Kudo classifications were 0 to IIa flat elevation (444; 36.6%) and IIIs (301; 24.8%), respectively. En bloc and R0 resection rates were 56.6% and 54.3%, respectively. Smaller lesions, rectal location, and procedure type (endoscopic submucosal dissection) were associated with significantly higher en bloc and R0 resection rates. Bleeding and perforation rates were 5% and 6.6%, respectively. Increased age was a predictor for bleeding (OR 1.06; 95% CI, 1.03-1.09; p < 0.0001). Lesion size was a predictor for perforation (OR 1.02; 95% CI, 1.00-1.03; p = 0.03). The tumor recurrence rate was 6.6%. En bloc (HR 1.41; 95% CI, 1.05-1.93; p = 0.02) and R0 resection (HR 1.49; 95% CI, 1.11-2.06; p = 0.008) were associated with decreased recurrence risk. LIMITATIONS Single-center, retrospective study. CONCLUSIONS Outcomes of advanced endoscopic resections can be predicted by patient-related and lesion-related characteristics. See Video Abstract . PREDICTORES DE LA RESECCION R, EN BLOQUE Y LAS COMPLICACIONES POR RESECCIONES ENDOSCPICAS AVANZADAS EN CASOS DE NEOPLASIA COLORRECTAL RESULTADOS DE PROCEDIMIENTOS ANTECEDENTES:Las técnicas avanzadas de resección endoscópica se utilizan para el tratamiento de neoplasias colorrectales que no son susceptibles de resección colonoscópica convencional. La literatura sobre los predictores de los resultados de las resecciones endoscópicas avanzadas, especialmente en una unidad de cirugía colorrectal, es limitada.OBJETIVO:Determinar los predictores de resultados a corto y largo plazo después de resecciones endoscópicas avanzadas.DISEÑO:Serie de casos retrospectivos.LUGAR:Centro de tercer nivel de atención.PACIENTES:Pacientes sometidos a resecciones endoscópicas avanzadas por neoplasias colorrectales desde noviembre de 2011 hasta agosto de 2022.INTERVENCIÓNES:Resección endoscópica de la mucosa, disección endoscópica submucosa (ESD), ESD híbrida, cirugía laparoscópica endoscópica combinada.PRINCIPALES MEDIDAS DE RESULTADO:Los predictores de resección en bloque y R0, sangrado y perforación se determinaron mediante modelos de regresión logística univariables y multivariables. Se utilizaron modelos de regresión de Cox para determinar los predictores de recurrencia del tumor.RESULTADOS:Se resecaron 1.213 lesiones colorrectales en 1.047 pacientes [edad media 66 (58-72) años, 484 (46,2%) mujeres, índice de masa corporal medio 28,6 (24,8-32,6) kg/m 2 ]. La mayoría de las neoplasias se encontraban en el colon proximal (898, 74%). El tamaño medio de la lesión fue de 30mm (RIC: 20-40, rango: 0-120). 911 (75,1%) lesiones tenían intervenciones previas. Las clasificaciones de París y Kudo más comunes fueron 0-IIa elevación plana (444, 36,6%) y III (301, 24,8%), respectivamente. Las tasas de resección en bloque y R0 fueron del 56,6% y 54,3%, respectivamente. Las lesiones más pequeñas, la ubicación rectal y el tipo de procedimiento (ESD) se asociaron con tasas de resección en bloque y R0 significativamente más altas. Las tasas de sangrado y perforación fueron del 5% y 6,6%, respectivamente. La edad avanzada [1,06 (1,03-1,09), p < 0,0001] fue un predictor de sangrado. El tamaño de la lesión [1,02 (1,00-1,03), p = 0,03] fue un predictor de perforación. La tasa de recurrencia del tumor fue del 6,6%. En bloque [HR 1,41 (IC 95% 1,05-1,93), p = 0,02] y la resección R0 [HR 1,49 (IC 95% 1,11-2,06), p = 0,008] se asociaron con un menor riesgo de recurrencia.LIMITACIONES:Estudio unicéntrico, retrospectivo.CONCLUSIONES:Los resultados de las resecciones endoscópicas avanzadas pueden predecirse según las características del paciente y de la lesión.

Abstract
Background and study aims Endoscopic submucosal dissection (ESD) allows removal of tumors en-bloc. Western adoption of ESD has been hindered by its steep learning curve. Western data regarding ESD learning curve are limited. We analyzed the learning curve of a single endoscopist at a tertiary referral center in the United States. Patients and methods All consecutive ESDs performed by a single endoscopist at a tertiary referral center in the United States from 2015 through 2022 were identified. Descriptive statistics and CUSUM analysis were used to describe the learning curve for en-bloc, R0 resection, and resection speed. Results In our study, 503 patients with 515 lesions were included. Severe submucosal fibrosis was found in 17% of the lesions. The rates of en-bloc, R0, and curative resections were 81.9%, 71.1%, and 68.4%, respectively. CUSUM analysis showed that the learning curve plateaued at 268, 347, and 170 cases for en-bloc resection, R0 resection, and achieving a resection speed > 9 cm 2 /hr. Fibrosis significantly affected the R0 resection rate in the regression analysis (95% confidence interval 0.21-0.55). In colonic ESD curve analysis, the learning plateau was reached after 185 cases for both en-bloc and R0 resection. Conclusions Following ex-vivo training in an animal model, an untutored expert operator achieved competency in ESD between 250 and 350 procedures. Our data can inform development of future training programs in the West.

Abstract
BACKGROUND The existing ex vivo models of endoscopic submucosal dissection (ESD) cannot simulate intraoperative hemorrhage well. We aimed to establish an ESD training method by applying an ex vivo training model with continuous perfusion (ETM-CP). METHODS Four training sessions were conducted for 25 novices under the guidance of 2 experts. Eventually, 10 novices completed ESD operations on a total of 89 patients after the training. The resection effectiveness, resection speed, complication rate, and novice performance before and after the training were compared. The data regarding the effects of the training and the model were gathered through a questionnaire survey. RESULTS In terms of the simulation effect of the model, ETM-CP was evaluated as similar to the live pig in all aspects (P > 0.05). The questionnaire analysis revealed that the ESD theoretical knowledge, skill operation, and self-confidence of novices were improved after the training (P < 0.05). The resection time per unit area had a correlation with the number of training periods (rs = - 0.232). For novice performance, the resection time per unit area was shortened (P < 0.05). There was no difference in patient performance between the novice group and the expert group after the training in terms of en bloc resection, R0 resection, complication rate, endoscopic resection bleeding (ERB) score, muscularis propria injury (MPI) score, and resection time per unit area (P > 0.05). CONCLUSION The ETM-CP is effective for ESD training.

Abstract
BACKGROUND We aimed to compare the outcomes and the cost differences of endoscopic submucosal dissection (ESD) procedures in the endoscopy suite (ES) versus the operating room (OR). MATERIALS AND METHODS The procedures in the OR were compared with procedures performed in the ES for demographics, lesion characteristics, procedure outcome, and procedure charges. The study included 163 procedures in the ES and 73 in the OR. RESULTS Both were similar in age, sex, body mass index, and intraprocedural and postoperative 30-day (late) complications. ES cases had significantly greater polyp size, were more commonly right-sided polyps, and had shorter hospital stays, with similar en bloc and margin-negative resection rates. The overall cost ratio of ESD procedures in ES to OR was 0.47 ( P <0.001). CONCLUSIONS Colorectal ESD procedures performed in the ES have similar efficacy and safety as those in the OR. Procedures performed in the ES were associated with a shorter length of stay and significant periprocedural cost savings.

Abstract
BACKGROUND AND AIMS As there is still no consensus about the adequate training strategy for ESD in Western countries, we evaluated unsupervised prevalence-based learning curves including detailed organ-specific subgroup analysis. METHODS The first 120 ESDs of four operators (n = 480) were divided into three groups (1: ESD 1-40, 2: ESD 41-80, 3: ESD 81-120). Outcome parameters were rates of technical success, en bloc and R0 resection, the resection speed, rates of conversion to EMR, curative resection, adverse events, surgery due to adverse events, and recurrence. In addition, we analyzed the achievement of quality benchmarks indicating levels of expertise. RESULTS After exclusion of pretreated lesions, 438 procedures were enrolled in the final analysis. Technical success rates were > 96% with significant improvements regarding rate of en bloc resection (from 82.6 to 91.2%), resection speed (from 4.54 to 7.63 cm2/h), and rate of conversion to EMR (from 22.0 to 8.1%). No significant differences could be observed for rates of R0 resection (65.9 vs. 69.6%), curative resection (55.8 vs. 55.7%), adverse events (16.3 vs. 11.7%), surgery due to adverse events (1.5 vs. 1.3%), and recurrence (12.5 vs. 4.5%). Subgroup and benchmark analysis revealed an improvement in esophageal, gastric, and rectal ESD with achievement of competence levels for the esophagus and stomach within 80 and most of the benchmarks for proficiency level within 120 procedures. Some of the benchmarks could also be achieved in rectal ESD. CONCLUSIONS This trial confirms safety and feasibility of unsupervised ESD along the initial learning curve with prevalence-based indication and exclusion of colonic cases.

Abstract
BACKGROUND Colorectal endoscopic submucosal dissection is technically demanding, and the traction offered by gravity, cap, or clip-with-line during conventional endoscopic submucosal dissection remains unsatisfactory. Robotic systems are still under development and are expensive. We proposed double-scope endoscopic submucosal dissection with strong and adjustable traction offered by snaring the lesion with additional scope. OBJECTIVE This study aimed to test the novel double-scope endoscopic submucosal dissection with snare-based traction. DESIGN This was a retrospective study that reviewed double-scope endoscopic submucosal dissection compared with matched conventional endoscopic submucosal dissection, and size, location, morphology, and pathology between groups were compared. SETTINGS This study was conducted in a referral endoscopy center in a local hospital. PATIENTS This study included patients with colorectal lesions receiving double-scope endoscopic submucosal dissection and matched conventional endoscopic submucosal dissection. MAIN OUTCOME MEASURES The pathological completeness, procedure time, and complications were analyzed. RESULTS Fifteen double-scope endoscopic submucosal dissection procedures, with 11 lesions located in the proximal colon with a median size of 40 mm, were performed. The median procedure time of double-scope endoscopic submucosal dissection was 32.45 (interquartile range, 16.03-38.20) minutes. The time required for second scope insertion was 2.57 (interquartile range, 0.95-6.75) minutes; for snaring, 3.03 (interquartile range, 2.12-6.62) minutes; and for actual endoscopic submucosal dissection, 28.23 (interquartile range, 7.90-37.00) minutes. All lesions were resected completely. No major complication was encountered. The procedure time was significantly shorter than that of 14 matched conventional endoscopic submucosal dissections (54.61 [interquartile range, 33.11-97.25] min; p = 0.021). LIMITATIONS This was a single-center, single-operator, retrospective case-controlled study with limited cases. CONCLUSIONS This study confirmed the feasibility of double-scope endoscopic submucosal dissection with snare-based traction to shorten procedure time and to simplify endoscopic submucosal dissection. Additional trials are required.

Abstract
BACKGROUND Using conventional endoscope to perform endoscopic submucosal dissection (ESD) is difficult because of the one-handed operation and blind dissection caused by gravity. Poor visualization of the submucosal plane causes ESD to be associated with a high risk of bleeding and perforation. This study aimed to develop a novel ESD-assistive robot system and to evaluate its efficacy. METHODS A novel flexible auxiliary single-arm transluminal endoscopic robot (FASTER) was developed. A total of 36 artificial lesions in ex vivo porcine stomachs were removed using the FASTER-assisted ESD method (n = 18) and the conventional ESD method (n = 18). Lesions were 2 cm or 4 cm in diameter, located on the anterior and posterior walls of the antrum. Primary outcome measurements were dissection time and dissection speed. RESULTS The dissection time in FASTER-assisted ESD was significantly shorter than that in conventional ESD (7 min vs 13 min, p = 0.012), mainly because of the faster dissection speed (148.6 vs 97.0 mm2/min, p = 0.002). The total procedure time in FASTER-assisted ESD was shorter than that in conventional ESD, but the difference was not significant (16 min vs 24 min, p = 0.252). Complete en bloc resection was achieved in all lesions. No perforations were detected. The FASTER exhibited the ability of regrasp, multidirectional traction, and proper tension control during ESD. CONCLUSION FASTER significantly increased the dissection speed by providing proper traction and achieving good submucosal vision. This new device is expected to facilitate ESD in clinical practice.

Abstract
Endoscopic submucosal dissection was introduced in Japan for the mini-invasive treatment of early gastric cancer, as part of national screening program considering high prevalence of disease in these latitudes. This technique allows en-bloc curative oncological excision and to obtain in a single step R0-resection, characterization, histological staging and potential cure of the tumor with a very high cost-benefit balance. Over the years, Western endoscopists have adopted endoscopic submucosal dissection, achieving good rates of efficacy, long-term improved outcomes and safety, with low risk of local recurrence comparable to those obtained in Asian institutes. However, according to some authors, the excellent outcomes from East country could not be representative of the Western experience. Despite epidemiological differences of early gastric cancer, scant volume data and limitations in training opportunities between Western and Eastern countries, European Society of Gastrointestinal Endoscopy have adopted Japanese guidelines and developed a European core curriculum for endoscopic submucosal dissection training. Endoscopists should be able to estimate the probability of performing a curative resection by considering the benefit/risk relationship case-by-case in order to implement a correct decision-making process.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) enables the curative resection of early malignant lesions and is associated with reduced recurrence risk. Due to the lack of comprehensive ESD data in the West, the German ESD registry was set up to evaluate relevant outcomes of ESD. METHODS The German ESD registry is a prospective uncontrolled multicenter study. During a 35-month period, 20 centers included 1000 ESDs of neoplastic lesions. The results were evaluated in terms of en bloc, R0, curative resection rates, and recurrence rate after a 3-month and 12-month follow-up. Additionally, participating centers were grouped into low-volume (≤20 ESDs/y), middle-volume (20-50/y), and high-volume centers (>50/y). A multivariate analysis investigating risk factors for noncurative resection was performed. RESULTS Overall, en bloc, R0, and curative resection rates of 92.4% (95% confidence interval [CI], 0.90-0.94), 78.8% (95% CI, 0.76-0.81), and 72.3% (95% CI, 0.69-0.75) were achieved, respectively. The overall complication rate was 8.3% (95% CI, 0.067-0.102), whereas the recurrence rate after 12 months was 2.1%. High-volume centers had significantly higher en bloc, R0, curative resection rates, and recurrence rates and lower complication rates than middle- or low-volume centers. The lesion size, hybrid ESD, age, stage T1b carcinoma, and treatment outside high-volume centers were identified as risk factors for noncurative ESD. CONCLUSION In Germany, ESD achieves excellent en bloc resection rates but only modest curative resection rates. ESD requires a high level of expertise, and results vary significantly depending on the center's yearly case volume.

Abstract
OBJECTIVE Although scissor-type knives such as the Stag-Beetle (SB) Knife Jr are expected to result in a safe and easy colorectal endoscopic submucosal dissection (CR-ESD), information regarding the learning curve is lacking. Therefore, this study evaluated the learning curve with using SB Knife Jr. MATERIALS AND METHODS We retrospectively reviewed 507 CR-ESD procedures performed in 464 patients using SB Knife Jr. The primary endpoint was a learning curve to achieve a satisfactory complete resection rate. The secondary endpoints were learning curves to achieve a satisfactory en bloc resection rate, curative resection rate, and resection speed. RESULTS The complete, en bloc, and curative resection rates were 91.9%, 95.9%, and 84.0%, respectively. Moving average analysis showed that 39 cases were required for a complete resection rate of >80%, 41 for an en bloc resection rate of >90%, and 50 for a curative resection rate of >75%. We divided the procedure into three phases using the cumulative sum method: I, II, and III (cases 1-36, 37-119, and 120-507, respectively). Although we found no significant between-phase differences, the complete resection rate showed an increasing trend in Phase III (83.3 vs. 89.2 vs. 93.3%; p = .099). The en bloc resection rate (91.7 vs. 91.6 vs. 97.2%; p = .047) and resection speed (20.5 vs. 7.2 vs. 6.8 min/cm2; p < .001) were greater in Phase III. Despite the larger specimen size (27.3 vs. 38.2 vs. 40.4 mm; p < .001) and more severe fibrosis (p < .001) in Phase III, the procedure time was shorter (73.8 vs. 57.8 vs. 54.2 min; p = .041). The curative resection rate was not significantly different between phases. CONCLUSIONS SB Knife Jr enables safe and easy CR-ESD during the introductory period compared to the conventional tip-type knife and has an acceptable learning curve. Therefore, using this knife will encourage the widespread adoption of CR-ESD in Asian general hospitals and non-Asian countries.

Abstract
Background Colorectal endoscopic submucosal dissection (ESD) is an effective but challenging procedure. To facilitate ESD, several methods that apply traction are available; however, the optimal one remains to be established. The aim of this study was to evaluate the feasibility and safety of the double-endoscope assisted ESD (DEA-ESD) by improving traction to treat complex colorectal lesions. Methods Naïve or previously treated lesions in the rectum and sigmoid colon were included. A grasping forceps advanced through a small-caliber endoscope (GIF-XP190N, Olympus Medical Systems, Tokyo, Japan, 5.4 mm outer diameter) was used to apply traction to the mucosal flap. Lesions were deemed complex when they exceeded a total of nine points on the SMSA scoring system (size, morphology, site, and access) and recurrent when they were previously treated with endoscopic mucosal resection (EMR). Outcome measures included procedural success, total procedure time, complications, and recurrence rate at 3-month follow-up. Results Nine patients (mean age 62.3 ± 14.5 years) were included; five had rectal and four had tumors in the sigmoid colon. The median SMSA score was 14 (SMSA Level IV—complex polyp), while three patients were pre-treated with EMR. DEA-ESD was technically feasible in all cases. En bloc resection and R0 resection rates were 100%, respectively, with a mean procedure time of 128.4 ± 54.1 min. No immediate or delayed complications occurred. Conclusions DEA-ESD is a feasible and safe method for treating complex or recurrent tumors in the rectum and distal colon.

Abstract
Background and study aims There are no data showing the outcome of ESD during live endoscopy events (LEE). ESD performed during the Augsburg Endo-Update LEE were compared with matched routine procedures with the aim of demonstrating non-inferiority of LEE ESD. Patients and methods ESD performed during the Endo-Update between 2006 and 2018 were reviewed. The controls were routine procedures matched according to age, location and lesion size. Resection, recurrence, survival and complication rates, procedure time and propofol sedation were assessed. Clinically relevant margins were assumed for resection and complication rates, procedure time and propofol sedation quantity. Results Thirty-eight ESD were performed in the given time period, and were compared with 38 matched routine ESD. En bloc and curative resection rates in the LEE group and in the control group were 100 % and 87 % as well as 84 % and 71 % respectively, while procedure times were 135 and 125 minutes, respectively. Non-inferiority was demonstrated for resection rates and procedure time. The complication rate was lower in the LEE group as compared with the control group (5 % vs 13 %) while propofol sedation was similar in both groups (863 mg vs 872 mg). Recurrence and 5-year survival rates for both groups were 4 % vs 0 % and 70 % vs 65% respectively. Conclusions The resection rate and procedure time of ESD during LEE was non-inferior to those of routine ESD procedures. Comparison of the complication rates, however, was inconclusive owing to the low patient number and complication risk in both groups.

Abstract
Pioneered in Japan to address the limitations of endoscopic mucosal resection in the stomach, endoscopic submucosal dissection (ESD) has been applied throughout the gastrointestinal tract, including the colorectum. ESD is technically challenging and has been slowly gaining traction in the West. However, for the committed and resourceful endoscopist, proficiency in ESD can still be achieved. Moreover, improvement in techniques and devices are likely to ease the learning curve while improving procedural duration, safety, and efficacy of colorectal ESD. This article reviews challenges and methods in learning ESD in the United States and provides a primer on performing ESD and full-thickness resection in the colorectum.

Abstract
Aim The aim of the study was to evaluate costs associated with colonic endoscopic submucosal dissection (ESD) for treatment of colorectal cancer. Methods The study is a retrospective analysis of data on 395 patients treated by colonic ESD. Results The operation, consumable items, and medication accounted for 71% of the total costs for colonic ESD treatment. Medication and consumable items' costs were higher if lesions occurred in the transverse colon and right hemicolon compared to the left hemicolon. Medication, consumable items, and total costs were higher for larger lesions. Lesion numbers and carcinoma were associated with higher medication, consumable items, operation, and total costs. Positive surgical margins and complications of hemorrhage or perforation were positively correlated with higher costs for medication, consumable items, and total costs. Conclusion Labor costs for doctors and nurses remain low in China. Costs for medication and consumable items were higher for treatment involving the transverse colon or right hemicolon (vs. the left hemicolon), larger lesions, carcinoma, and a positive surgical margin. A benchmark cost estimate for ESD treatment including 4 days of postoperative hospitalization was determined to be approximately 5400 USD.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is an advanced method allowing en bloc resection of large and complex lesions in colon and rectum. Herein, the European experience of colorectal ESD was systematically reviewed in the medical literature to determine the clinical efficacy and safety of colorectal ESD in Europe. MATERIAL AND METHODS A systematic search of PubMed for full-text studies including more than 20 cases of colorectal ESD emanating from European centres was performed. Data were independently extracted by two authors using predefined data fields, including efficacy and safety. RESULTS We included 15 studies containing a total of 1404 colorectal ESD cases (41% in the colon) performed between 2007 and 2018. Lesion size was 40 mm (range 24-59 mm) and procedure time was 102 min (range 48-176 min). En bloc resection rate was 83% (range 67-93%) and R0 resection rate was 70% (range 35-91%). Perforation rate was 7% (range 0-19%) and bleeding rate was 5% (range 0-12%). The percentage of ESD cases undergoing emergency surgery was 2% (range 0-6%). Additional elective surgery was performed in 3% of all cases due to histopathological findings showing deep submucosal invasion or more advanced cancer. The recurrence rate was 4% (range 0-12%) after a median follow-up time of 12 months (range 3-24 months). CONCLUSIONS This review shows that ESD is effective and safe for treating large and complex colorectal lesions in Europe although there is room for improvement. Thus, it is important to develop standardized and high-quality educational programs in colorectal ESD in Europe.
