The Advantages and Disadvantages Between Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction After Laparoscopy-assisted Distal Gastrectomy for Gastric.

To search which is the better reconstructions by comparing and analyzing the advantages and disadvantages between Uncut Roux-en-Y and Billroth II reconstructions after laparoscopy-assisted distal gastrectomy for gastric cancer. Method: It's a prospective study including all patients underwent laparoscopy-assisted distal gastrectomy (LADG) in the First Hospital of Jilin University, from February 2016 to February 2017. All surgical procedures will be performed by the single surgery team, which is leaded by professor Wang Quan. The reconstruction method will be selected randomly from Uncut Roux-en-Y and Billroth II anastomosis by drawing lots preoperatively without distinct indications. Clinical data, operation data and perioperative complications and related physiological indexes of differences.

Uncut Roux-en-Y Reconstruction will be used after laparoscopy-assisted distal gastrectomy for early gastric cancer.

Billroth II Reconstruction will be used after laparoscopy-assisted distal gastrectomy for early gastric cancer.

All surgical procedures will be performed by the single surgery team ,which is leaded by professor Wang Quan. Uncut Roux-en-Y construction will be used in this group.

The time of reconstruction during operations of Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction

In the morning of 1-6 days after operation , monitor the number of gastric juice's potential of hydrogen ( pH) value through gastric tube and write down the data. So if the data is greater than 7,the complication of bile reflux happened

the amount of blood loss during operations of Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction

During the operation the amount of blood loss will be recorded in the operating note by nurses in milliliters.

During the upper gastrointestinal radiography，if there is residual food,the meglumine diatrizoate will be separate and then write down the number.

During the upper gastrointestinal radiography,if there is meglumine diatrizoate refluxing to esophagus,it will be observed and written down in number.

all patients of this clinical trial will be investigated by Gastroesophageal reflux disease questionnaire(GerdQ),and all patients whose score is beyond 8 will be collected.

Inclusion Criteria: Clinical diagnosis of distal gastric cancer underwent laparoscopy-assisted distal gastrectomy Exclusion Criteria: have simultaneously other cancer have severe systemic inflammatory disease ,serious illness such as diabetes, chronic lung diseases have upper gastrointestinal surgery can't bear the gastric tube the period is too late or the tumor is too large to carry on a laparoscopy assisted radical distal gastrectomy
