Low delayed bleeding and high complete closure rate of mucosal defects with the novel through-the-scope dual-action tissue clip after endoscopic resection of large nonpedunculated colorectal lesions (with video).

BACKGROUND AND AIMS: Complete closure after endoscopic resection of large nonpedunculated colorectal lesions (LNPCLs) can reduce delayed bleeding but is challenging with conventional through-the-scope (TTS) clips alone. The novel dual-action tissue (DAT) clip has clip arms that open and close independently of each other, facilitating tissue approximation. We aimed to evaluate the rate of complete closure and delayed bleeding with the DAT clip after endoscopic resection of LNPCLs. METHODS: This was a multicenter prospective cohort study of all patients who underwent defect closure with the DAT clip after EMR or endoscopic submucosal dissection (ESD) of LNPCLs ≥20 mm from July 2022 to May 2023. Delayed bleeding was defined as a bleeding event requiring hospitalization, blood transfusion, or any intervention within 30 days after the procedure. Complete closure was defined as apposition of mucosal defect margins without visible submucosal areas <3 mm along the closure line. RESULTS: One hundred seven patients (median age, 64 years; 42.5% women) underwent EMR (n = 63) or ESD (n = 44) of LNPCLs (median size, 40 mm; 74.8% right-sided colon) followed by defect closure. Complete closure was achieved in 96.3% (n = 103) with a mean of 1.4 ± .6 DAT clips and 2.9 ± 1.8 TTS clips. Delayed bleeding occurred in 1 patient (.9%) without requiring additional interventions. CONCLUSIONS: The use of the DAT clip in conjunction with TTS clips achieved high complete defect closure after endoscopic resection of large LNPCLs and was associated with a .9% delayed bleeding rate. Future comparative trials and formal cost-analyses are needed to validate these findings. (Clinical trial registration number: NCT05852457.).

Trends and outcomes of percutaneous endoscopic gastrostomy in hospitalized patients with malignant and nonmalignant ascites: a nationwide population study.

BACKGROUND: Patients with ascites resulting from chronic debilitating diseases often require non-oral enteral nutrition and undergo placement of a percutaneous endoscopic gastrostomy (PEG) tube. The aim of our study was to assess the nationwide trends and outcomes of PEG tube placement among patients with ascites. METHODS: Using the Nationwide Inpatient Sample (NIS), we conducted a retrospective analysis of adult patients (≥18 years) who underwent PEG tube placement (n=789,167) from 2010-2014. We divided these patients into 2 groups: with or without ascites. We compared demographics, complications, and in-hospital outcomes between the groups. STATA-13 was used for statistical analysis. Statistical significance was assigned at P<0.05. RESULTS: Patients with ascites who underwent PEG tube placement were found to have a significantly higher rate of complications, including peritonitis (7.52 vs. 0.72%; P<0.001), aspiration pneumonia (20.41 vs. 2.69%; P<0.001), hemoperitoneum (0.72 vs. 0.19%; P<0.001), procedure-related hemorrhage (1.69 vs. 0.9%; P<0.001) and esophageal perforation (0.51 vs. 0.47%; P<0.001). In addition, these patients also had higher in-hospital mortality (16.33% vs. 7.02%; P<0.001) despite having a relatively lower prevalence of comorbidities. Length of stay was longer in the ascites group (28.08 vs. 19.45 days; 0.001). Over the study period, however, we observed an increasing trend for PEG tube placement in hospitalized patients with ascites. CONCLUSION: PEG tube placement in hospitalized patients with ascites is associated with significantly higher mortality, a longer stay, and more procedure-related complications.

Zollinger Ellison Syndrome in a Patient with Multiple Endocrine Neoplasia Type 1: A Classic Presentation.

Zollinger Ellison Syndrome (ZES) is characterized by a wide spectrum of conditions including severe gastroesophageal reflux disease, peptic ulcer disease, watery diarrhea, and weight loss. We present a case of a 60-year-old woman being evaluated for severe dyspepsia, vomiting, and chronic diarrhea, who was diagnosed to have ZES associated with a pancreatic neuroendocrine tumor, in the setting of multiple endocrine neoplasia (MEN) type 1. Although cases of ZES have been reported previously, we believe that our case is a classic presentation of ZES diagnosed on the basis of typical radiologic, endoscopic, and endosonographic features.
