Short-term Outcomes of SILS+1 Versus CLS for Distal Gastric Cancer

A Prospective Randomized Controlled Study of the Short-term Efficacy of Single-hole Plus One-hole Total Laparoscopic Surgery Versus Five-hole Total Laparoscopic Surgery for Distal Gastric Cancer

To evaluate the short-term outcomes of single-incision plus one-port laparoscopic surgery (SILS + 1) versus conventional laparoscopic surgery(CLS) for distal gastric cancer whose clinical stage was cT1-3N0-2M0

The gastric cancer patients with cT1-3N0-2M0 were randomized at a 1:1 ratio to the CLS group or the SILS+1group, then it will evaluate the short-term outcomes between two groups.

Inclusion Criteria:

• pathological diagnosis of gastric cancer
• clinically diagnosed cT1b-3N0-2M0 lesions according to the 8th Edition of the American Joint Committee on Cancer(AJCC) Cancer Staging Manual(measured using abdominal CT)
• tumor size ≤ 5cm
• planned to conduct subtotal gastrectomy

Exclusion Criteria:

• preoperative radiotherapy and chemotherapy
• tumor perforation
• severe mental disease
