Influence of Arrangement of Small Intestine Order on the Recovery of Bowel Function After Laparoscopic Colorectal Surgery

Study Overview
=================
Brief Summary
-----------------
The method of arranging and restoring the position of the small intestine under laparoscopy is used to determine whether it can promote the recovery of intestinal function after colorectal surgery.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Arrangement group<br>Experimental group: After the completion of laparoscopic-assisted colorectal cancer surgery, the chief surgeon performed laparoscopic small bowel arrangement before closing the abdomen, straightening the small bowel from the colon-small bowel anastomosis or the ileocecal valve to the ligament of Trevor, and restoring the original position of the small bowel. Afterwards, close the abdomen. | Procedure: Arrangement of small intestine order before close the abdomen<br>* After the completion of laparoscopic-assisted colorectal cancer surgery, the chief surgeon performed laparoscopic small bowel arrangement before closing the abdomen, straightening the small bowel from the colon-small bowel anastomosis or the ileocecal valve to the ligament of Trevor, and restoring the original position of the small bowel.
