Filter by:The patients with upper gastric cancer (cT1N0M0) or gastroesophageal adenocarcinoma (diameter less than 4 cm) will be enrolled into this study. Each of these patients will undergo radical proximal gastrectomy and be randomly allocated into one of the two groups, double tract anastomosis group or esophagogastrostomy group. The following data will be collected to compare the difference between the two reconstruction methods: the rate of reflux esophagitis, postoperative quality of life, economic expenditure, the safety of operation, postoperative recovery, postoperative nutrition status and oncological effect. Through the comprehensive analysis, the result of this study will elucidate the best of the reconstruction method after proximal gastrectomy.
The incidence of gastric cancer is the highest in China, and surgery is one of the most effective treatment methods. Da Vinci robot radical gastrectomy for gastric cancer has the advantage of minimally invasive and fine operation. However, due to complicated perigastric anatomy, abundant blood supply and wide distribution of lymph nodes, it is widely used in clinical use of .Combine the 3D printing technique with imaging examination (digestive endoscopy,3Dct cta/ctv, etc.) ,making the 3D model of da Vinci robot assisted radical gastrectomy can fully show the anatomical relationship around gastric cancer, determine the flow and variation of splenic portal vessels, and the distribution of splenic hilar lymph nodes. In order to eliminate the imagination difference of spatial anatomical structure before operation, it is easier for surgeons to optimize the operation plan, to control the operation process and to improve the accuracy, and to adopt individualized operation suitable for the patients.

The treatment of early gastric cancer can be divided into endoscopic resection and surgery, and the precise staging of early gastric cancer is very important to prevent unnecessary surgery or additional surgery after the procedure. The possibility of endoscopic resection is determined by the risk of lymph node metastasis. The risk factors of lymph node metastasis of early gastric cancer are lesion size, presence of ulceration, histologic differentiation, and depth of invasion. In contrast to other factors, the factor of invasion depth is relatively difficult to predict by using the conventional white light endoscopy (WLE). Therefore, the endoscopic ultrasonography (EUS) has been tried to use for prediction of the invasion depth. However, many studies reported that the accuracy of endoscopic ultrasonography for predicting the depth of invasion was varied. A system consisting of a magnifying endoscope combined with narrow-band imaging (NBI), with the spectral band width narrowed by optical filters, was developed to enhance visualization of mucosal surface structure and vascular architecture. There were some reports that the magnifying endoscopy with narrow band imaging (ME-NBI) is superior to predict the histologic differentiation, depth of invasion and lesion margin than WLE. In this study, we divide the patients with suspected early gastric cancer (EGC) into the two groups as group using conventional WLE and EUS and group using WLE and ME-NBI, and try to compare the accuracy of EUS and ME-NBI for predicting the invasion depth of EGC. We also try to analyze the factors that affect the accuracy for predicting of depth such as characteristics of cancer lesion and histologic differentiation of cancer in each group. In addition, we try to analyze the characteristic imaging findings of ME-NBI for early gastric cancer and gastric adenoma and evaluate the efficacy of ME-NBI for early gastric cancer and gastric adenoma diagnosis.
Gastric cancer is the one of the leading cause of cancer death in the worldwide. Gastric cancer originates from the most superficial mucosal epithelial cells of the stomach wall, which can occur in various parts of the stomach, and can invade different depths and breadth of the gastric wall. Without chemotherapy treatment the GC patients' Median Survival Time (MST) lasts only 3-4 months. Although treated with multi-chemotherapy MST has been improved, the drugs show strong toxicities in the patients. Thus the more accurate, lower toxicity, targeted antitumor drugs are put into second-line treatment program for advanced gastric cancer. Apatinib, a novel targeted inhibitor of VEGF receptor 2 (VEGFR2), shows significant antitumor activity in the patients with GC. The purpose of this study is to determine whether apatinib plus capecitatine can improve progression free survival in patients with advanced gastric cancer.
Gastric cancer is a common gastrointestinal tumor, and surgical operation is still the main method of gastric cancer treatment. Reported for the first time since 1994, the laparoscopic gastric cancer radical prostatectomy, laparoscopic technique is widely applied in the field of gastrointestinal surgery, has gradually replaced the traditional open operation as the main mode of surgical treatment for gastric cancer. Although laparoscopy has many advantages, there are still disadvantages, such as the discomfort of the physician, the reverse operation, and the ease of shaking, which hinder the application of laparoscopy. In recent years, the Da Vinci robot assisted gastric resection has become a new way to treat gastric cancer. Compared with the traditional laparoscopy and laparotomy, the operation of the robot is more precise and flexible, with obvious advantages of minimally invasive and good application value and prospect. The aim of the study is to compare value (outcomes/costs) of surgery in patients with Gastric Cancer by 3 approaches: open, laparoscopic, and robotic.First of all, the investigators will collect 500 cases of Gastric Cancer patients, randomly assigned for the open, laparoscopic, and robotic group. Secondly, to analyzing the demographic data,basic treatment and follow-up data, including the operation time, blood loss, the number of cut edge positive, the distances of cut edge away from the tumor edge, the cases of anastomotic fistula bleeding, stenosis, average such confinement, the meal time, cost of treatment, tumor recurrence rate, the presence of residual stomach, upset stomach and frequency, reflux esophagitis, bile reflux gastritis and other indicators.
The purpose of this study is to investigate the efficacy and safety of HIPEC plus apatinib and S-1 in the conversion therapy of gastric cancer with positive exfoliative cancer cells
Postoperative gastroesophageal reflux is one of the most common complications of distal gastrectomy. With more attention paid on it by surgeons, several new operation methods have been practised. Among all these, distal gastrctomy with Billroth II + Braun anastomosis was reported to be an useful method to decrease postoperative reflux rate. Meanwhile, the direction of anastomotic peristalsis has also been reported to affect the anastomosis and thus make difference in reflux rate. We design this study to investigate the potential effect and the superiority of antiperistaltic vs isoperistaltic Billroth II + Braun reconstruction in distal gastrectomy.
