To achieve ″tube-free″ by improving the perioperative management of laparoscopic colorectal surgery. The laparoscopic ″tube-free″ colorectal surgery and conventional laparoscopic colorectal surgery which indwelled nasogastric tube, peritoneal drainage tube and urinary catheter postoperative were compared in the postoperative recovery and complications to proof the feasibility and safety of laparoscopic ″tube-free″ colorectal surgery.

Forty-nine patients with colorectal cancer were randomly divided into conventional indwelling three tube operation group (control group) (twenty-three cases) and "tube-free" operation group (TF group) (twenty-six cases). The baseline characteristics of the patients, the postoperative recovery index, 40-item quality of recovery scoring system (QoR-40) assessment and the postoperative safety index were compared.

There were three patients who had postoperative urinary retention in the TF group. The postoperative days of opioid analgesics (Z=5.241, P<0.001) and days of hospitalization (t=3.2, P=0.002) in the TF group were significantly shorter than those in the control group. The difference was not statistically significant. There was no significant difference in the incidence of complications such as anastomotic leakage, intestinal obstruction, wound infection, pulmonary infection, heart failure, deep vein thrombosis and cardio cerebral vascular accident between the two groups (P>0.05). The total score of QoR-40 at forty-eight hours after operation in the TF group was significantly higher than that in the control group (Z=5.774, P<0.01), and the sub-score of comfort, self-care and pain in the TF group was significantly better than that in the control group (P<0.01).

Conventional indwelling nasogastric tube, catheter and drainage tube after colorectal surgery does not benefit the patients. Laparoscopic ″tube-free″ colorectal surgery which reduces postoperative discomfort, improves patient quality recovery after operation without increasing the occurrence of short-term postoperative complications is a safe and feasible treatment measures.
