Filter by:The safety and efficacy of Laparoscopy-assisted Pylorus-preserving Gastrectomy (LAPPG) for the treatment of early gastric cancer (EGC) remain controversial. The investigators conducted a randomized controlled trial to compare LAPPG and laparoscopic distal gastrectomy with D2 lymph node dissections for EGC.
The aim of the present study was to assess whether it was necessary to conduct magnifying endoscopy with narrow band imaging (ME-NBI) targeted biopsy compared with endoscopic forceps biopsy (EFB) from white light endoscopy in diagnosing early gastric cancer (EGC). Meanwhile, the investigators proposed the most cost-effective way to diagnose EGC.
The gastric cancer is the second most frequently diagnosed cancer and the third leading cause of cancer death in China.80%-90% patients were detected at middle and later stage.The five-year survival rate for advanced gastric cancer patients is less than 10% due to the shortage of effective treatment method.The five-year survival rate for early gastric cancer patients is beyond 90%.The reason for poor diagnosis and treatment is that current methods do not achieve the diagnosis of early gastric cancer.Endoscopy with biopsy is still the main method for confirming gastric cancer.But it is limited to identify early gastric cancer and it leads to the low diagnostic rate of early gastric cancer. Infrared endoscopic imaging is a new great potential method of diagnosis of early gastric cancer, since the first report in the 1990s, people have been exploring in this field. Through intravenous injection of exogenous contrast medium, such as the indocyanine green, it makes mucosal lesions highlight,and avoids the interference of background light.If specific target molecular is linked to the contrast medium,the specific imaging of the lesion can be presented. What is more,due to the strong penetration power of infrared light,its imaging depth also increases significantly.Indocyanine green had also been demonstrated safe in clinical studies and widely used. On this basis,we apply for the research about near-infrared endoscopy to diagnose early gastric cancer,and discuss its feasibility of the infrared endoscopy to diagnose early gastric cancer and clinical value.
The aim of the present study was to evaluate characteristics of background mucosa in early gastric cancer (EGC), and to seek for the optimal assessment for EGC screening.
Endoscopic submucosal dissection is commonly performed under light to moderate sedation, and minimizing patient movement is of key importance for successful outcome. Propofol has widely replaced benzodiazepines as sedative drug of choice, and has been reported to enhance the quality of procedure in our past study. However, despite higher satisfaction scores of the endoscopists and faster post-procedural recovery, patient satisfaction scores were found to be higher in patients that received midazolam and meperidine instead of propofol and remifentanil. This seems to be due to the anterograde amnestic effects of midazolam rather than the quality of sedation itself. Investigator hypothesized that by premedicating the patient with low lose midazolam before receiving sedation for ESD with propofol and fentanyl, patient satisfaction would be enhanced without affecting endoscopic performance.
This study evaluates whether Helicobacter pylori eradication improves precancerous lesions including glandular atrophy and intestinal metaplasia as well as metachronous cancers or dysplasias after endoscopic mucosal resection for gastric cancer.
AIM Verified if the first stage of the Train the trainer (TTT)plan could improve the young endoscopist's ability to detect the early gastric cancer（EGC）. METHOD 1. a retrospective analysis of the ten young endoscopist's painless gastroscopy examination from January 1, 2014 to December 31, 2014. According mainly to the endoscopic report and pateint's History, quantity of gastroscope, gastric cancer and the early gastric cancer. 2. the first step of the train the trainer plan(TTT) activised in March 19-20,2015,which including the diagnosis and operation "hand in hand" teach by Professor Yano Takeshiin,and the case discussion,and so on. Five young endoscopist accepted the TTT plan and the other five not accepted. 3. The five doctors who accepted the TTT do the gastroendoscopy in accordance with the TTT content (for the T1 period),.(1) the patient's name, (2)gender, (3)age,(4)past medical history (Helicobacter pylori<HP>, gastritis, gastric ulcer, oral drug operation, etc.),（5）gastroscope operation time,(6)the location of the lesion- longitudinal (upper, middle and lower),(7) the location of the lesion -circumferential (lessor curvature, Greater curvature, anterior wall, posterior wall),(8) lesion size, (9)conventional white-light imaging (red, white, no change), (10)magnifying endoscopy with narrow-band imaging (EM-NBI) microvascular and mirosurface pattern VS classification system(VSCS) (boundaries, microvascular pattern and microsurface pattern; don't do it), (11)microscopy types (uplift type, flat type, concave type or IIc I/IIa or IIb), (12)histological type (differentiated and undifferentiated type) and (13) pathological (low grade neoplasia, high-level neoplasia etc.). For the treatment of endoscopy submucosal dissection (ESD) patients, further pathological results were recorded after ESD, including the pathology, edge and basal conditions. The other five doctors do the gastroendoscopy as they do before. (300 cases / person) 4. 2-4 TTT activity ;The five doctors who accepted the TTT do the gastroendoscopy in accordance with the TTT content (for the T2-T4 period),.The other five doctors do the gastroendoscopy as they do before. 5. Statistics the number of early gastric cancer have been found by the five young doctors, and how mang gastroscopy they have done.pay attention to The rates of EGC detection.
The purpose of this study is to determine whether Endoscopic Submucosal Dissection combine with Laparoscopic Regional Lymph node Dissection for early gastric cancer can improve Disease-free survival ？
Endoscopic submucosal dissection (ESD) is an advanced technique that enables en bloc resection of superficial tumors in the gastrointestinal tract. ESD, however, is a time-consuming procedure that requires a high level of endoscopic skill to achieve a desirable oncologic outcome. Several procedure-related complications may occur after ESD. Especially, iatrogenic ulcer bleeding after ESD can be a concern for both endoscopists and patients. In order to reduce the bleeding rate, proton pump inhibitors (PPIs) are administered after ESD. In addition, ulcer protective agents such as rebamipide can be added to PPIs for accelerating ulcer healing. We aimed to evaluate the efficacy of polaprezinc for healing of iatrogenic ulcer.
A new Magnetic-controlled Capsule Endoscopy (MCE) was developed by ANKON and got SFDA's approval in China in 2013. It has recently been evaluated to compare the diagnostic accuracy of MCE with that of standard gastroscopy for gastric diseases in 70 patients with encouraging results (In Press). To further testify the diagnostic accuracy of MCE for both the diffuse and focal diseases in stomach, we performed this single-blinded multi-center prospective study compared MCE with gastroscopy in patients with gastric symptoms and indication for upper GI Endoscopy.
