Lesion-Based Convolutional Neural Network in Diagnosis of Early Gastric Cancer.
Lesion-Based Convolutional Neural Network in Diagnosis of Early Gastric Cancer. Clin Endosc. 2020 Mar;53(2):127-131 Authors: Yoon HJ, Kim JH Abstract Diagnosis and evaluation of early gastric cancer (EGC) using endoscopic images is significantly important; however, it has some limitations. In several studies, the application of convolutional neural network (CNN) greatly enhanced the effectiveness of endoscopy. To maximize clinical usefulness, it is important to determine the optimal method of applying CNN for each organ and disease. Lesion�-based CNN is a type of deep learning model designed to learn the entire lesion from endoscopic images. This review describes the application of lesion-based CNN technology in diagnosis of EGC. PMID: 32252505 [PubMed]
This report presents the case of a 55-year-old woman with a previous Roux-en-Y gastric bypass who was shown by endoscopy to have an invasive adenocarcinoma located in the distal thoracic esophagus. This necessitated an excision of the thoracic esophagus and the gastric pouch. A laparoscopic and thoracoscopic Ivor-Lewis esophagogastrectomy was performed for this complex patient with esophageal adenocarcinoma. The remnant stomach was fashioned into a gastric conduit using a 60-mm linear stapler with a staple height of 4.1 mm (Echelon, Ethicon Endosurgery, Blue Ash, OH). The reconstruction was performed using a 25-mm Orvil (C...
This study aimed to evaluate the usefulness of HALDG compared with laparoscopy-assisted distal gastrectomy (LADG). Consecutive patients who underwent HALDG (n=58) or LADG (n=90) for stage I gastric cancer between 2005 and 2016 were eligible. Operative time was significantly shorter and blood loss was significantly higher in HALDG than in LADG (P
In some countries with high prevalence of gastric cancer, endoscopic screening has demonstrated benefit from early diagnosis. Therapeutic interventions in endoscopic mucosal resection and submucosal dissection are increasingly used to treat early gastric neoplasia suggesting possible benefit to early detection. However, in other regions with a high prevalence of gastric cancer there are no standardized upper esophagogastroduodenoscopy (EGD) screening programs.
Gastric cancer is the 6th leading cause of cancer-related death worldwide. Gastric intestinal metaplasia (GIM) is a premalignant condition that can lead to gastric adenocarcinoma. However, GIM continues to be challenging to diagnose, and random gastric biopsies can often miss GIM. Narrowband imaging (NBI) has shown potential in the detection of GIM, but pooled estimates are not known compared to standard white light endoscopy (WLE).
Irreversible electroporation (IRE) has recently been conceived as a new minimally invasive ablation method, using microsecond electric fields to produce nanoscale defects in the cell membrane bilayer and induce cell death while keeping all other molecules, including the extracellular matrix, intact. Here, we present a in vivo study that examines the effects of IRE on the stomach, an organ whose collateral damage is of particular concern in the anticipated use of IRE for treatment of abdominal cancers.
Endoscopic submucosal dissection (ESD) has become a widely accepted as a standard treatment for early gastric cancer (EGC) with differentiated histology. However, therapeutic outcome of ESD for undifferentiated cancer is still controversial. As ESD is a technique that leaves the at-risk native stomach, patients with EGC who have previously underwent ESD have the potential to develop metachronous gastric cancer (MGC). Given evidence has demonstrated that the cumulative incidence of MGC after endoscopic resection is not negligibly low.
Endoscopic submucosal dissection (ESD) is considered the procedure of choice in the treatment of early gastric cancer (EGC) in selected cases. It offers advantages over open or laparoscopic surgery because of the minimally invasive approach, organ preservation, higher postoperative quality of life, lower medical costs and with a similar efficacy in terms of oncologic aspects. The cure rates described in the Japanese literature are about 88% -90%. Despite very low levels of major complications, ESD is usually performed as an inpatient procedure, in a range of 2 to 7 days in both eastern and western centers.
Progression of endoscopic diagnosis contributes improvement of detecting early gastric cancer (EGC). Endoscopic resection like endoscopic submucosal dissection (ESD) achieves surefire treatment of EGC. Now metachronous gastric cancer (MGC) after ESD becomes a problem. We analyzed the patients who had MGC after ESD to clarify the feature of MGC.
Endoscopic submucosal dissection (ESD) is a curative method for some cases of early gastric cancer (EGC). However, there are still some patients who underwent additive gastrectomy after ESD because of lymph node metastasis (LNM) risk. If an accurate predicting for the risk of LNM before ESD is possible, appropriate treatment strategy could be established at the timing of decision for ESD. We aimed to investigate pre-procedural features for predicting the risk of LNM in EGC.
This study aimed to determine risk factors related to the development of IM to guide proper management in Thailand.
