الوصف: AIM The main aim of this study was to compare the long-term outcome of a conventional colorectal endoscopic submucosal dissection (ESD) in which submucosal dissection was continued throughout until the completion of resection (ESD-T) to hybrid endoscopic submucosal dissection (ESD-H) in the colorectum. METHOD Medical records of 836 colorectal neoplasia patients treated by ESD-T or ESD-H were reviewed. ESD-H was defined as colorectal ESD with additional snaring in the final stage of the procedure. Primary outcomes were the overall and metastatic recurrence rates. Secondary outcomes were short-term outcomes such as the en bloc resection rate, procedure time and adverse events. RESULTS The overall recurrence rate was higher in the ESD-H than in the ESD-T group (5.7% vs 0.7%, P = 0.001). The metastatic recurrence rate showed no significant difference between these groups (1.4% vs 1.4%, P = 1.000). Multivariate analysis revealed that a failed en bloc resection (hazard ratio 24.097; 95% CI 5.446-106.237; P

الوصف: Background and aim The feasibility of endoscopic submucosal dissection (ESD) as a treatment option for dysplasia in ulcerative colitis (UC) has been reported, but the associated therapeutic decision-making and clinical outcomes have not been extensively investigated. Methods We retrospectively reviewed 25 UC patients who were referred for potential ESD of non-polypoid or sessile dysplasia. We analyzed the treatment decisions and the ESD and colectomy outcomes for this patient group. Results All lesions were located at the colitic segments. The median UC duration was 13.4 years. A colectomy was recommended for 10 patients because of ulceration with indistinct borders (one patient), non-ulceration with indistinct borders (two patients), and non-lifting signs (seven patients). The remaining 15 patients underwent ESD. The en bloc and R0 resection rates were 93.3% and 80%, respectively. The median hospitalization periods were 1 (range, 1-2) day after ESD and 7 (range, 5-30) days after colectomy. No procedure-related complications occurred after ESD, but early and late postoperative complications occurred in two (22.2%) and six (66.7%) of the colectomized patients, respectively. Fourteen ESD cases were followed endoscopically for a median period of 24.7 (range, 5.2-64.8) months. Local recurrence occurred in 2 (14.3%) patients, and metachronous recurrence was identified in two separate patients (14.3%). Conclusions Endoscopic submucosal dissection is a feasible endoscopic treatment option for UC-associated dysplasia showing noninvasive pit or vascular patterns, no surface ulceration, distinct borders, and appropriate lifting after submucosal injection. Meticulous endoscopic surveillance is essential to monitor for local or metachronous recurrence of dysplasia after ESD.

الوصف: Background/Aims Endoscopic mucosal resection with circumferential mucosal incision (CMI-EMR) may offer benefits comparable to those of endoscopic submucosal dissection (ESD), while requiring less technical proficiency than ESD. Methods We retrospectively compared the outcomes of CMI-EMR (n=34) and size-matched ESD (n=102), which were performed by a Korean endoscopist for colorectal epithelial lesions of 20–35 mm. Procedural parameters of CMI-EMRs performed by an American ESD novice (n=30) were compared with those performed by the Korean endoscopist. Results The lesion size was 22.3±3.9 mm and 22.9±2.4 mm in the CMI-EMR and size-matched ESD groups, respectively (p=0.730). The resection time was 12.7±7.0 minutes in the CMI-EMR group and 45.6±30.1 minutes in the ESD group (p

الوصف: Few studies have compared the costs of colorectal endoscopic submucosal dissection (ESD) and endoscopic piecemeal mucosal resection (EPMR). Here, we aimed to investigate the cost-effectiveness of these approaches by analyzing clinical outcomes and costs. Data from patients undergoing colorectal ESD and EPMR were retrospectively reviewed. Clinical outcomes (procedure time, complete resection, and recurrence) were compared, and total direct costs (procedural and follow-up) were assessed. Data from 429 ESD and 115 EPMR patients were included in the analysis. The complete resection rate was significantly higher (83.9% vs. 32.2%, p

الوصف: Background and Aims Colorectal endoscopic submucosal dissection (ESD) is difficult and time consuming. Optimization of ESD with snaring (optimized hybrid ESD) may shorten the procedure time. The purpose of this study was to prospectively compare ESD and optimized hybrid ESD in the colorectum. Methods We prospectively enrolled 70 patients with colorectal neoplasia ≥20 mm. The patients were randomized to receive either ESD (36 patients) or optimized hybrid ESD (34 patients). In the optimized hybrid ESD group, snare resection was performed after an adequate amount of submucosal dissection. The primary outcome was procedure time. Secondary outcomes were en bloc and complete resection rates and adverse event rates. Results ESD could not be completed in 5 patients (13.9%) in the ESD group because of technical difficulties. We tried hybrid ESD to finish the resection, and en bloc resection was achieved in 4 patients (80%). The mean procedure time was shorter in the optimized hybrid ESD group compared with the ESD group (27.4 vs 40.6 minutes; P = .005). The en bloc resection rates were similar (94.1% vs 100%; P = .493), as were the complete resection rates (91.2% vs 93.5%; P > .999) and perforation rates (3 patients [8.8%] vs 2 patients [6.5%]; P > .999). Conclusions Optimized hybrid ESD achieves shorter procedure times than ESD, with similar en bloc resection rates and adverse event rates. Optimized hybrid ESD in the colorectum may offer an easy alternative to colorectal ESD and a rescue method for failed ESD cases. (Clinical trial registration number: NCT01944540.)

الوصف: BACKGROUND/AIMS We aimed to investigate the factors associated with piecemeal resection of colorectal neoplasia (CRN), in spite of endoscopic submucosal dissection (ESD). MATERIALS AND METHODS We analyzed the retrospective data for colorectal ESD cases from January 2005 to April 2014. We also reviewed the piecemeal endoscopic mucosal resection (EMR) for CRNs ≥20 mm, performed over the same period. RESULTS En bloc resection was possible in 648 (85.7%) of 756 lesions in 740 patients. Multivariate analysis showed that hybrid ESD (odds ratio (OR), 29.07; 95% confidence interval (CI), 15.46-54.65; p

الوصف: We aimed to evaluate the recurrence rate of colorectal neoplasia showing histologic lateral margin involvement after en bloc endoscopic submucosal dissection (ESD). We reviewed 527 colorectal lesions that were removed by en bloc ESD from 2005 to 2013 and followed by endoscopy. Based on the postprocedural pathologic reports, the lesions were categorized as follows: lesions with clear deep and positive lateral margins (n = 63) and lesions with R0 resection (n = 299). The tumor size was 45.7 ± 21.1 mm in the lateral margin-positive group and 30.6 ± 15.1 in the R0 group (P

الوصف: The therapeutic outcome of endoscopic submucosal dissection (ESD) for large protruding tumors has not yet been evaluated. We aimed to compare the outcomes of ESD in protruding tumors with those of laterally spreading tumors (LSTs). Endoscopic submucosal dissection was attempted in 218 patients with 220 colorectal tumors ≥30 mm in diameter (67, protruding tumors; 153, LSTs) from July 2007 to June 2014. We retrospectively reviewed patient medical records, therapeutic outcomes, and procedure-related adverse events. This study defined lesions with a height of 10 mm or more as protruding tumors and those with a height under 10 mm as LSTs. The mean lesion diameter, height, and volume were 43.8, 9.5 mm, and 13.6 cm3, respectively. The mean procedure time was 75.5 min. Deep submucosal cancer was more frequent in protruding tumors than in LSTs (11.9 vs. 2.6 %, P = 0.005). Severe fibrosis was more common in protruding tumors than in LSTs (19.4 vs. 3.9 %, P

الوصف: Background/Aims: Although colorectal endoscopic submucosal dissection (ESD)-related perforation is not uncommon, the factors affecting clinical outcomes after perforation have not been investigated. This study was designed to investigate the factors influencing the clinical course of ESD-related colon perforation. Methods: Forty-three patients with colorectal ESD-related perforation were evaluated. The perforations were classified as endoscopic or radiologic perforations. The patients’ medical records and endoscopic pictures were analyzed. Results: The clinical outcomes were assessed by the duration of nil per os, intravenous antibiotics administration, and hospital stays, which were 2.7±1.5, 4.9±2.3, and 5.1±2.3 days, respectively. Multivariate analyses revealed that a larger tumor size, ESD failure, specific endoscopists, and abdominal pain were independently related to a poorer outcome. The time between perforation and clipping was 15.8±25.4 minutes in the endoscopic perforation group. The multivariate analysis of this group indicated that delayed clipping, specific endoscopists, and abdominal pain were independently associated with poorer outcomes. Conclusions: Tumor size, ESD failure, abdominal pain, and the endoscopist were factors that affected the clinical outcomes of patients with colorectal ESD-related perforation. The time between the perforation and clipping was an additional factor influencing the clinical course of endoscopic perforation. Decreasing this time period may improve outcomes.

الوصف: Background and Aims The incidence of rectal neuroendocrine tumors (NETs) is increasing, and most small rectal NETs can be treated endoscopically. Cap-assisted EMR (EMR-C) was suggested as an effective treatment for rectal NETs in a few studies. We aimed to compare the outcomes of conventional EMR, EMR-C, and endoscopic submucosal dissection (ESD) for the treatment of rectal NETs. Methods A total of 138 rectal NETs were treated endoscopically by a single endoscopist at Asan Medical Center. We analyzed 122 rectal NETs that had been removed by using EMR (n = 56), EMR-C (n = 34), or ESD (n = 32). Results The histologic complete resection rate was higher in the EMR-C group than in the EMR group (94.1% vs 76.8%, P = .032). Intraprocedural bleeding tended to be more frequent in the EMR-C group than in the EMR group (8.8% vs 0%, P = .051). No differences in the rates of adverse events or histologic complete resections were observed between the EMR-C group and the ESD group for 6-mm to 8-mm NETs; however, the procedure time was significantly shorter in the EMR-C group (3.9 ± 1.1 minutes) than in the ESD group (19.0 ± 12.1 minutes) ( P Conclusions EMR-C is the preferable technique for endoscopic resection of small rectal NETs.
