Abstract Artificial Intelligence ( ai ) systems are precious support for decision-making, with many applications also in the medical domain. The interaction between md s and enjoys a renewed interest following increased possibilities of deep learning devices. However, we still have limited evidence-based knowledge context, design, psychological mechanisms that craft an optimal human– collaboration. In this multicentric study, 21 endoscopists reviewed 504 videos lesions prospectively acquired...
Accurate in-vivo optical characterization of colorectal polyps is key to select the optimal treatment regimen during colonoscopy. However, reported accuracies vary widely among endoscopists. We developed a novel intelligent medical device able seamlessly operate in real-time using conventional white light (WL) endoscopy video stream without virtual chromoendoscopy (blue light, BL). In this work, we evaluated standalone performance computer-aided diagnosis (CADx) on prospectively acquired...
Pembrolizumab is an immune checkpoint inhibitor (ICI) that demonstrated to enhance the prognosis of patients with advanced lung cancer. However, adding immunotherapy clinical practice has brought new challenges, such as immune-related adverse events (irAEs), which have changed chemotherapy's previously well-understood safety profile. Immune-mediated hepatitis, although less prevalent and extensively studied, represents a significant toxicity may evolve into potentially severe complication,...
Introduction: Gastrointestinal neuroendocrine tumors (GI-NETs) are being more frequently diagnosed and treated by endoscopic resection (ER) techniques. However, comparison studies of the different ER techniques or long-term outcomes rarely reported. Methods: This was a single-center retrospective study analyzing short after gastric, duodenum, rectal GI-NETs. Comparison between standard EMR (sEMR), with cap (EMRc), submucosal dissection (ESD) made. Results: Fifty-three patients GI-NET (25 15...
Objectives The management of individuals with gastric intestinal metaplasia (GIM) includes biopsies for its staging and to diagnose Helicobacter pylori (Hp ). Advanced-stage GIM can be estimated by endoscopy through EGGIM, a new device permits the real-time assessment ammonia identification Hp infection. aim this study was assess simultaneous use EGGIM avoid reduce burden care in clinical practice. Methods A multicentre involving 101 consecutively enrolled patients [52% male; 65(18–85)...
Here we report a case of 61-year-old woman who underwent en-bloc endoscopic submucosal dissection (ESD) 10mm depressed lesion (Paris 0-IIc, Figure A) in the mid-esophagus. Histopathology showed with high-grade squamous dysplasia (R0). On follow-up endoscopy at 6 and 12 months scar was regular, without signs recurrence. Seven after last endoscopy, patient presented chest pain dysphagia. Endoscopy an ulcero-vegetating tumor 3cm same location previous ESD (Figure B), biopsies poorly...
Abstract Text 62 years-old male submitted to a total gastrectomy due gastric cancer.Within 72 hours, the patient developed sepsis.CT revealed an anastomotic leak.Endoscopy showed 45% dehiscence with large-sized cavity.Endoluminal vacuum therapy(EVT)was placed intracavitary.After third replacement, presented hemorrhage through transnasal tube.New endoscopy EVT in situ.After removal, 3 cm granulated cavity clot its distal portion was identified. Given tissue granulation and possible...
<b><i>Introduction/Aim:</i></b> Gastric neuroendocrine tumors (GNETs) frequently have an indolent clinical course, despite their metastatic potential. The aim of the study was to identify prognostic factors associated with overall survival and risk metastases evaluate impact serial measurements chromogranin A (CgA). <b><i>Methods:</i></b> authors performed a retrospective cohort including consecutive patients GNET diagnosed between 2010 2019,...
Anastomotic leakage after esophagectomy is associated with high mortality and impaired quality of life.The objective this work was to determine the effectiveness management esophageal anastomotic (EAL) for gastroesophageal junction (GEJ) cancer.Patients submitted GEJ cancer at a tertiary oncology hospital between 2014 2019 (n = 119) were retrospectively reviewed EAL risk factors its outcomes determined.Older age nodal disease identified as independent leak (adjusted OR 1.06, 95% CI...
Introduction The cumulative lifetime risk of gastric cancer (GC) in patients with Lynch syndrome (LS) is reported to be 8%. There limited evidence on specific factors for GC and no agreement among guidelines endoscopic surveillance schedule LS patients. Aims methods We conducted a retrospective cohort study identify precancerous conditions (chronic atrophic gastritis intestinal metaplasia) case–control compare the prevalence these control group. Results included 385 (40.5% male, mean age...
Aims Immune-checkpoint inhibitors are a fundamental piece in the treatment of several malignancies. These immunotherapies present specific toxicities related to their mechanism action, commonly referred as immune-related adverse events (irAE). Among gastrointestinal irAE, upper GI involvement is infrequent, and gastritis rarely reported.
Aims To detect the prevalence of small bowel polyps, namely non-duodenal in patients with Familial Adenomatous Polyposis (FAP) who underwent Videocapsule Endoscopy (VE).
Abstract Text 1st case: woman with metastatic breast cancer,admitted for lithiasic cholecystitis. Exploratory laparoscopy showed invasion of the gallbladder by liver metastases.The patient underwent EUS-GBD successful placement LAMS. 2nd man cholangiocarcinoma admitted acute cholecystitis peri-vesicular abscess. Initially submitted to percutaneous cholecystostomy without success and then cholecistoduodenostomy (+LAMS). Due persistent fever, endoscopic clearance stent obstruction was needed...
Aims Self-expandable metal stents (SEMS) are a minimally invasive treatment for anastomotic leaks (AL). Our aim was to compare clinical and safety outcomes of fully covered (FC) partially (PC) SEMS [1].
