Prevention of Esophageal Stricture After Whole Circumferential Endoscopic Resection: A Review for Endoscopists.

The incidence of esophageal stricture without stricture prophylaxis measures after whole circumferential endoscopic resection is almost 100%, which substantially decreases the patients' quality of life and requires multiple sessions of endoscopic balloon dilation. To date, there are many reports concerning the prevention of esophageal stricture after whole circumferential endoscopic resection. Oral steroid may be effective for preventing esophageal stricture after whole circumferential endoscopic resection.

Comparison between endoscopic submucosal tunnel dissection and endoscopic submucosal dissection for superficial neoplasia at esophagogastric junction: a case-matched controlled study of a single center from China.

Background: So far, little evidence is available for the comprehensive comparison of endoscopic submucosal tunnel dissection (ESTD) with endoscopic submucosal dissection (ESD) for the treatment of superficial neoplasia at esophagogastric junction (EGJ).

Methods: EGJ superficial neoplasia patients with ESTD treatment between January, 2021 and August, 2020 were retrospectively reviewed and individually matched at 1:1 ratio with those with ESD treatment according to lesion size, specimen area and lesion location, forming ESTD and ESD group, respectively. A sample size of 17 patients was collected for each group.

Hybrid endoscopic submucosal dissection: An alternative resection modality for large laterally spreading tumors in the cecum?

Background: Endoscopic resection for large, laterally spreading tumors (LSTs) in the cecum is challenging. Here we report on the clinical outcomes of hybrid endoscopic submucosal dissection (ESD) in large cecal LSTs.

Methods: We retrospectively reviewed data from patients with cecal LSTs ≥ 2 cm who underwent ESD or hybrid ESD procedures between January of 2008 and June of 2019.

Autologous skin-grafting surgery to prevent esophageal stenosis after complete circular endoscopic submucosal tunnel dissection: a case-matched controlled study.

Background: The incidence of postoperative stenosis after endoscopic resection of wholly circumferential superficial esophageal squamous cell neoplasms (SESCNs) is extremely high.

Methods: Between January 2011 and April 2019, 19 patients who underwent autologous skin-grafting surgery (ASGS) after complete circular endoscopic submucosal tunnel dissection (ccESTD) were enrolled to form the ASGS group. Cases in the ASGS group were individually matched at a 1:1 ratio to cases undergoing fully covered esophageal stent (FCES) placement alone (FCES group) based on pathological diagnosis, curative resection, longitudinal length of ulceration, lack of stent migration, time to stent removal, follow-up period and operators.

Efficacy and safety of endoscopic submucosal tunnel dissection for rectal laterally spreading tumors.

Background: Evidence that comprehensively compares the efficacy and safety of endoscopic submucosal tunnel dissection (ESTD) with endoscopic submucosal dissection (ESD) for rectal laterally spreading tumors (LSTs) is limited.

Methods: Between January 2009 and June 2018, 143 rectal LSTs in 143 patients who had undergone either ESD (n = 84) or ESTD (n = 59) were included in the study. One-to-one propensity score matching (PSM) was performed, and 50 pairs were selected.

Clinical experience of using a novel self-help inflatable balloon to prevent esophageal stricture after circumferential endoscopic submucosal dissection.

Although endoscopic submucosal dissection (ESD) is gradually becoming a first-line treatment for superficial esophageal neoplasms (SEN), strictures occur in almost 100% of cases after circumferential ESD. A standard method to prevent stricture has not been established. Thus, we propose a novel self-help inflatable balloon to prevent stricture.

Inhibitory role of S-nitrosoglutathione in the aggregation of frozen platelets, and its effect on the expression of membrane glycoproteins.

The aim of this study was to explore the effects of S-nitrosoglutathione (GSNO) on the aggregation of frozen platelets, the platelet nitric oxide (NO) content and the expression of membrane glycoproteins. The level of frozen platelet aggregation was measured using a platelet aggregation analyzer, while the content of NO was measured by the nitrate reductase method and the expression of frozen platelet membrane glycoproteins was determined by flow cytometry. The level of frozen platelet aggregation was reduced from 35.

Survey of spinal cord injury-induced neurogenic bladder studies using the Web of Science.

Objective: To identify global trends in research on spinal cord injury-induced neurogenic bladder, through a bibliometric analysis using the Web of Science.

Data Retrieval: We performed a bibliometric analysis of studies on spinal cord injury-induced neurogenic bladder using the Web of Science. Data retrieval was performed using key words "spinal cord injury", "spinal injury", "neurogenic bladder", "neuropathic bladder", "neurogenic lower urinary tract dysfunction", "neurogenic voiding dysfunction", "neurogenic urination disorder" and "neurogenic vesicourethral dysfunction".
