Conventional laparoscopic surgery (CLS) for colorectal cancer has been demonstrated to be safe and feasible and present minimally invasive benefits including faster recovery, reduced postoperative pain and shorter hospital stay, also acquiring comparable oncologic outcomes with open surgery. To achieve further minimally invasive outcomes, SILS plus one port surgery was attempted by some surgeons. Preliminary results showed that SILS+1 could achieve better minimally invasive benefits than CLS while preserving oncologic feasibility. Till now, ERAS has been practiced in colorectal cancer surgery for approximately 20 years. Studies have proven that ERAS is safe and significantly improved the recovery course of patients during perioperative period, meanwhile, the expense could be greatly reduced. Based on ERAS studies protocols and SILS+1 trials, investigators tried to combine SILS+1 with ERAS, hopefully to provide patients with more safe, economic, feasible and rapid surgery and perioperative strategies.

SILS plus one port surgery and enhanced recovery after surgery protocol both are methods taking the minimally invasive benefits for the patients including faster recovery, reduced postoperative pain and shorter hospital stay.
Rehabilitative rate
The percentage of patients who met discharge criteria in the fourth day after surgery
Time frame: 4 days
Postoperative hospital stays
Days from surgery to discharge
Time frame: 1 month
Medical cost
The patient's expenses from surgery to discharge are recorded in RMB "yuan"
Time frame: 1 month
Postoperative pain score
Postoperative pain is recorded using the visual analog scale (VAS) pain score tool on postoperative day . On a scale of 1 to 10, the higher the score, the greater the pain.
Time frame: Once a day from 6 hours to the fourth day after surgery
Postoperative recovery index
The first Time to early mobilization(hour), flatus(hour), liquid diet(hour), soft diet(hour), removal of the Nasogastric tubes(hour) , removal of the peritoneal drainage(hour) are used to assess the postoperative recovery
Time frame: 1 month
Postoperative inflammatory immune response
It includes the number of white blood cells and lymphocytes,CRP, IL-6
Time frame: 3 days
compliance with ERAS measures
It is defined as if the patients complete every ERAS measure or not. We can defined it "yes " or "not".
Time frame: perioperative
6 min postoperative walking test(6MWT)
Study site, subject preparation, trial procedures, and medical monitoring refer to the 6MWT guidelines issued by the American thoracic society in 2002.
Time frame: Once a day from the frist to the fourth day after surgery
hospital readmissions
It can be defined as the number of patients readmitted within 30 days because of postoperative complications.
Time frame: 30days
Morbidity and mortality rates
Morbidity and mortality rates are defined as postoperative complications graded according to Clavien-Dindo within 30 days.
Time frame: 30 days
