After distal gastrectomy, duodenal stump closure, side to side anastomosis was underwent on the remnant stomach and jejunum,which was 25cm from Treitz ligament. Then underwent side to side anastomosis between jejunum about 35cm distance from gastrojejunostomy and jejunum about 5cm from Triez ligament . close the intestinal cavity on the input less than 5cm distance from the loop gastrojejunostomy anastomosis by using uncut Closure devices

After distal gastrectomy, duodenal stump closure, the investigators first underwent remnant stomach and upper jejunum side anastomosis. Then choose the jejunum about 25cm from Treitz ligament, premenstrual colon using a disposable cutting closure (or tubular stapling) in the rear wall of the stomach and jejunum anastomosis, common opening was closed with the (barbed wire) hand-stitched. After that, steps were same with the group A.

Uncut Closure devices would be used to close the intestinal cavity on the input less than 5cm distance from the loop gastrojejunostomy anastomosis.

Uncut Roux-en-Y anastomosis

Typical Billroth II anastomosis would be made after the Distal gastrectomy.

The investigators intend to conduct multi-center randomized controlled study to find if Uncut Roux-en-Y anastomosis to the distal gastric cancer patients after radical D2 can reduce the long-term complications, affect the quality of life, and improve the prognosis, comparing to Billroth II anastomosis.

Gastric cancer is still one of the most common malignant tumors, and gastric antrum cancer is still common. Radical surgery is the only way to treat gastric antrum cancer, surgical procedures and reconstruction are closely related with the prognosis and quality of life, the choice is crucial. Gastrojejunostomy after distal gastrectomy may affect the quality of radical surgery, and postoperative diet, nutritional status and quality of life. More and more centers tend to choose Billroth II anastomosis, but patients prone to have a variety of complications, including reflux gastritis and bile reflux, malnutrition, seriously affecting the quality of life and so on. According to preliminary pilot study found that, uncut Roux-en-Y anastomosis way can keep the continuity of nerve-muscle function of the reconstruction of digestive tract, and closes the input in order to reduce the incidence of reflux, for improving the nutritional status and reducing complications and improve quality of life. Therefore, the investigators intend to conduct multi-center randomized controlled study to find if Uncut Roux-en-Y anastomosis to the distal gastric cancer patients after radical D2 can reduce the long-term complications, affect the quality of life, and improve the prognosis.

Uncut Roux-en-y Anastomosis Reduce Postoperative Complication and Improve Nutritional Status After Distal Gastrectomy

The investigators would like to share the data to the Participating units.

This is a national-wide online survey, which aims to investigate the nutritional status and dietary intakes in Chinese discharged patients with cancer. It will provide relevant data for the "White Paper on Nutritional Diet of Cancer Patients in China", and also provide reference for the relevant work of nutrition support for cancer patients in clinical practice.

Nutritional status has significant impact on clinical outcome and quality of life in patients with cancer. Current surveys show that about 30-80% of patients with cancer have nutritional risk and/or malnutrition, and about 20% of the patients' death are directly caused by malnutrition. Appropriate and standardized nutrition therapy might not only improve the nutritional status, but also the clinical outcomes of patients with cancer, and improve their life quality and dignity.

At present, there is still lack of large-scale investigation and research on nutritional status and dietary intakes in discharged patients with cancer in China, and thus affects the overall level of nutritional management for cancer patients, as well as the formation of related guideline.

Therefore, we will conduct a national-wide cross-sectional online survey, which aim to investigate relevant data of nutritional status and dietary intakes among discharged patients with cancer. Data will be collected through an online semi-structured questionnaire using WeChat forms with a consent form. The link to the questionnaire was sent through emails, WeChat App groups, and other social media. The participants were encouraged to roll out the survey, and send the link to more patients as they could. On receiving and clicking the link, the participants will be directed to the information about the study and informed consent. After they accept to take the survey, they will fill up the demographic details and answer a set of questions related to nutritional status and dietary intake investigation.
