Perforation associated with endoscopic submucosal dissection for duodenal neoplasm without a papillary portion.

ABSTRACT: To investigate predictors of perforation after endoscopic resection (ER) for duodenal neoplasms without a papillary portion.This was a single-center, retrospective, cohort study conducted between April 2003 and September 2014. A total of 54 patients (59 lesions) underwent endoscopic mucosal resection (EMR) (n = 36) and endoscopic submucosal dissection (ESD) (n = 23). Clinical features, outcomes, and predictors of perforation were investigated.Cases of perforation occurred in eight (13%) patients (95%CI: 4.7%-22.6%). Three ESD cases required surgical management because they could not be repaired by clipping. Delayed perforation occurred in two ESD cases, which required surgical management, although both patients underwent prophylactic clipping. All patients with perforation who required surgery had no postoperative complications and were discharged at an average of 13.2 d after ER. Perforation after ER showed a significant association with a tumor size greater than 20 mm (P = 0.014) and ESD (P = 0.047).ESD for duodenal neoplasms exceeding 20 mm may be associated with perforation. ESD alone is not recommended for tumor treatment, and LECS should be considered as an alternative.

Minimally invasive management of large duodenal lipoma: endoscopic submucosal dissection.

Project description:ObjectiveThis study was performed to compare the clinical outcomes of large duodenal lipomas (DLs) of ≥2 cm between endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFTR).MethodsThis retrospective study included patients who underwent endoscopic resection of large DLs from June 2017 to March 2021 at our hospital. Clinicopathologic features, clinical outcomes, and follow-up endoscopy findings were retrospectively reviewed.ResultsTwenty-three patients (12 men) with a mean age of 57.4 years were included. The median tumor size was 28.4 ± 13.3 mm. ESD was performed in 19 patients, and EFTR was performed in 4. Complete resection was achieved in 21 patients. The operative time and postoperative hospital stay were significantly shorter in the ESD than EFTR group. Four patients in the EFTR group developed a fever; no other adverse events occurred. No patients required surgical intervention. During the average follow-up of 21.1 months, no residual tumor, recurrence, or metastasis was observed.ConclusionBoth ESD and EFTR provide minimally invasive, localized treatment of selected DLs. ESD might have some advantages in resecting large DLs in terms of procedure time and hospitalization.

Endoscopic Submucosal Dissection of Papillary Gastric Adenocarcinoma; Systematic Review.

Project description:This study evaluated the possibility of endoscopic submucosal dissection (ESD) for early gastric cancer with papillary adenocarcinoma (EGC-PAC). PAC, an uncommon pathologic type of stomach cancer, is classified into differentiated-type histology. However, aggressive features, including a high rate of submucosal invasion, lymphovascular invasion (LVI), and lymph node metastasis (LNM), have been reported in studies with surgical specimens. Treatment outcomes of ESD for EGC-PAC have not been precisely demonstrated. Core databases were sought for the following inclusion criteria: studies of endoscopic resection or surgery of EGC-PAC presenting the following therapeutic indicators; en bloc resection, complete resection, curative resection, recurrence, complications associated with procedures, LVI, or LNM that enabled an analysis of ESD possibility. Overall, 15 studies were included for systematic review. Frequent submucosal invasion and high LVI were noted in EGC-PAC. However, PAC was not significantly associated with LNM. Pooled en bloc resection, complete resection, and curative resection rates were 89.7% (95% confidence interval: 55.3%-98.4%), 85.3% (67.7%-94.2%), and 67% (43%-84.5%), respectively. No LNM was observed if EGC-PAC satisfied the curative resection criteria. ESD seems technically feasible, although a high LVI rate results in a lower rate of curative resection.

Current Challenge: Endoscopic Submucosal Dissection of Superficial Non-ampullary Duodenal Epithelial Tumors.

Project description:Opinion statementWith the widespread use of esophagogastroduodenoscopy in recent years, the detection rate of superficial non-ampullary duodenal epithelial tumors (SNADETs) is increasing. Most SNADETs are early-stage adenocarcinoma or benign conditions, including adenoma. Therefore, endoscopic resection is desirable from the perspective of quality of life. However, endoscopic resection for SNADETs has not yet been established. Endoscopic submucosal dissection (ESD) is the most promising method for the treatment of SNADETs, because ESD provides a high rate of en bloc resection and a low rate of recurrence regardless of the tumor size. However, the difficulty of the procedure and a high rate of severe adverse events including perforation and bleeding have become major problems. Various preventive countermeasures for adverse events, such as use of specific devices, endoscope stabilization methods, and endoscopic closure of the post-ESD ulcer using clips, are reported to reduce the risk of the adverse events of ESD for SNADETs. This article reviews and highlights the current state of ESD for SNADETs and new challenges towards safe and effective ESD.

Clinical importance of colonoscopy in patients with gastric neoplasm undergoing endoscopic submucosal dissection.

Project description:To evaluate the usefulness of total colonoscopy (TCS) for patients undergoing gastric endoscopic submucosal dissection (ESD) and to assess risk factors for colorectal neoplasms.Of the 263 patients who underwent ESD at our department between May 2010 and December 2013, 172 patients undergoing TCS during a one-year period before and after ESD were targeted. After excluding patients with a history of surgery or endoscopic therapy for colorectal neoplasms, 158 patients were analyzed. Of the 868 asymptomatic patients who underwent TCS during the same period because of positive fecal immunochemical test (FIT) results, 158 patients with no history of either surgery or endoscopic therapy for colorectal neoplasms who were matched for age and sex served as the control group for comparison.TCS revealed adenoma less than 10 mm in 53 patients (33.6%), advanced adenoma in 17 (10.8%), early colorectal cancer in 5 (3.2%), and advanced colorectal cancer in 4 (2.5%). When the presence or absence of adenoma less than 10 mm, advanced adenoma, and colorectal cancer and the number of adenomas were compared between patients undergoing ESD and FIT-positive patients, there were no statistically significant differences in any of the parameters assessed. The patients undergoing ESD appeared to have the same risk of colorectal neoplasms as the FIT-positive patients. Colorectal neoplasms were clearly more common in men than in women (P = 0.031). Advanced adenoma and cancer were significantly more frequent in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus (P = 0.019).In patients undergoing gastric ESD, TCS appears to be important for detecting synchronous double neoplasms. Advanced adenoma and cancer were more common in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus. Caution is therefore especially warranted in patients with these risk factors.
