A Real World Study of Laparoscopic Preservation of the Pylorus Gastrectomy

For the patients with early gastric cancer (T1), preoperative evaluation (gastroscope, ultrasound gastroscope and abdominal enhanced CT) showed that the tumor was located in the body of the stomach, and the margin was enough to retain the pylorus and non lymph node metastasis (N0). Lappg (D1 + lymph node dissection) and traditional laparoscopic distal gastrectomy (BII type anastomosis, D1 + lymph node dissection) were included A control study was conducted to evaluate the difference of long-term quality of life, gastric emptying rate, incidence of basic reflux gastritis, bile contraction function, immune index, nutritional index and disease-free survival and overall survival between the two groups.
