Hybrid endoscopic approaches for complex colorectal polyps with a non-lifting sign: the Greek experience.

Background: Hybrid approaches combining endoscopic full-thickness resection (EFTR) with conventional techniques (endoscopic mucosal resection [EMR], endoscopic submucosal dissection [ESD]) have enabled the resection of difficult fibrotic colorectal adenomas exhibiting a "non-lifting" sign, and polyps in difficult positions. We present our cohort treated with either EMR+EFTR or ESD+EFTR as salvage hybrid endoscopic approaches for complex colorectal polyps not amenable to conventional techniques.

Methods: Retrospective analysis included technical success, histological confirmation of margin-free resection, assessment of adverse events and follow up with histological assessment.

The Inflammatory Bowel Disease-Disk Tool for Assessing Disability in Inflammatory Bowel Disease Patients: Validation of the Greek Version.

Background: The Inflammatory Bowel Disease-Disk (IBD-Disk) is a physician-administered tool that evaluates the functional status of patients with Inflammatory Bowel Disease (IBD). The aim of our study was to validate the content of the IBD-Disk in a Greek cohort of IBD patients.

Methods: Two questionnaires [the IBD Disk and the IBD-Disability Index (IBD-DI)] were translated into Greek and administered to IBD patients at baseline visit, after 4 weeks and 6 months.

Granulomatous Peritonitis Secondary to Primary Sclerosing Cholangitis.

Primary sclerosing cholangitis (PSC) is a rare, chronic, and progressive disease of the liver characterized by cholestasis due to multifocal bile duct strictures. PSC can lead to liver fibrosis, and in 10-20% of cases, it leads to cholangiocarcinoma and end-stage liver disease. However, the pathogenesis of the disease is not clearly understood.

Cold snare polypectomy vs. hot snare polypectomy vs. argon plasma coagulation for small (5-9mm) left-sided colorectal polyps: a prospective randomized trial.

Objective: To compare recurrence rates among three endoscopic treatment modalities for 5-9 mm left-sided colorectal polyps.

Methods: Consecutive adults referred for elective colonoscopy (1/2015-1/2018) with at least one polyp of eligible size (5-9 mm) located distally to the splenic flexure were randomly assigned (1:1:1) to one of three treatment modalities: (1) cold snare polypectomy (CSP), (2) hot snare polypectomy (HSP) and (3) argon plasma coagulation (APC) ablation (50-60 W, flow: 2 l/min). The polyp site was marked with an endoscopic tattoo, and a follow-up colonoscopy with scar biopsies was performed >6 months after the index procedure.

Paradigm shift in management of acute iatrogenic colonic perforations: 24-year retrospective comprehensive study.

Through advanced endoscopic clipping techniques, endoscopic treatment of both diagnostic and therapeutic acute iatrogenic colonic perforations has been shown effective. The main purpose of this study was to compare the management of acute iatrogenic perforations (AIPs) of the colon before and after the introduction of advanced clipping techniques. We conducted a retrospective study from July 1996 to February 2020.

Experimental gastric endoscopic submucosal dissection: training in a porcine model.

Background: Endoscopic submucosal dissection (ESD) requires special skills and a long procedure time for a quality-controlled procedure. A universal training system remains to be established. Hands-on courses in animal models before advancing to the human colon appear to be essential, especially in Europe.

Use of a double-channel gastroscope reduces procedural time in large left-sided colonic endoscopic mucosal resections.

Background/aims: Endoscopic mucosal resection (EMR) of large colorectal lesions is associated with increased procedural time. The objective of this study was to evaluate the effect of double-channel gastroscope (DCG) use on the procedural time of EMRs in the rectosigmoid area.

Methods: All EMRs for sessile or flat rectosigmoid lesions ≥2 cm performed between July 2011 and September 2012 were retrospectively analyzed.

Sixty- versus thirty-seconds papillary balloon dilation after sphincterotomy for the treatment of large bile duct stones: a randomized controlled trial.

Background: Endoscopic biliary sphincterotomy followed by endoscopic papillary balloon dilation is a promising method for large stones. However, there are no data on the optimal duration of papillary balloon dilation after a biliary sphincterotomy.

Aims: To compare the effectiveness and complications of the endoscopic papillary balloon dilation for 60s versus 30s after endoscopic biliary sphincterotomy.

Intramural hematoma of the ascending colon leading to intraperitoneal hemorrhage: a possible post-polypectomy complication.

A 61-year-old male on anticoagulant therapy underwent an endoscopic multiple colon polypectomy in our Department according to established procedures. Several days later he developed an intramural colonic hematoma, which burst into the peritoneal cavity leading to fatal intra-peritoneal hemorrhage. Herein we present the case and discuss the causative role of the anticoagulant therapy but also of the endoscopic procedure .
