Laparoscopic Proximal Gastrectomy with Transrectal Specimen Extraction (GC-NOSES V)

Abstract

Proximal gastrectomy is a standard procedure for early gastric cancer or benign lesions in the upper stomach. Proximal gastrectomy with transrectal specimen extraction (GC-NOSES V) is mainly applicable to male and some female patients with early lesions in the upper stomach. On the basis of strict adherence to the radical resection of tumor and digestive tract reconstruction in the conventional laparoscopic surgery for gastric cancer, this procedure opens the rectum and extracts the specimen through the anus, which manifests the combination of minimally invasive surgery and function preservation surgery. This is a resection extraction NOSES procedure. The operating characteristics of this procedure are (1) radical resection of gastric cancer, dissection of lymph nodes, and digestive tract reconstruction completely under laparoscopy. The operation is the same as that in the conventional laparoscopic surgery, and the operation difficulty is not increased; (2) with no auxiliary incision in the abdominal wall, the function of abdominal wall is preserved, and the postoperative pain is reduced to the maximum extent. This procedure can not only ensure the radical resection of tumors but also reduce the damage to organs and tissues.
