Colon Neoplasm
Conditions
Brief summary
Objective:The comparison between total laparoscopic colectomy with intracorporeal anastomosis by overlap method and laparoscopic-assisted colectomy with extracorporeal anastomosis for colon cancer surgery. Condition or disease：Left colon cancer Intervention/treatment： Procedure:Intracorporeal left colectomy Overlap anastomosis Procedure: Extracorporeal left colectomy convention anastomosis
Detailed description
This a simple randomized, single-center, single-blind, randomized controlled trial study.The patients were randomly divided into experimental groups and control groups by computer.The perioperative recovery data, complications and oncology index of total laparoscopic colectomy with intracorporeal anastomosis and laparoscopic-assisted colectomy with extracorporeal anastomosis would be compared.
Interventions
PROCEDURETotal laparoscopic with intracorporeal anastomosis by overlap method
After the intestinal canal was dissociated and vascularized, the intestinal canal was nuded and cut off, and the distal and proximal intestinal canals were overlapped by 6 cm
PROCEDURELaparoscopic-assisted colectomy with extracorporeal anastomosis
After the corresponding colon and blood vessels were dissociated and treated, the carbon dioxide pneumoperitoneum was removed. The appropriate length of the incision was cut at the corresponding position of the abdomen, and the incision protector was placed. The tumor was lifted together with the free intestinal canal to the outside of the abdomen. The intestinal canals at the quasi-dismembered sites on both sides of the tumor were nuded, and the colon-colon functional end-to-end anastomosis was performed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The incidence of early complications | one month after surgery | According to Clavein Dindo grading standards（The scale is divided into four levels, with the minimum（Ⅰ） and the maximum（Ⅳ） level. The higher the level that more severe symptoms.）, the incidence of complications within one month after surgery, such as incision infection, bleeding, anastomotic leakage, ileus, etc., was counted |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| the time of first flatus | one month after surgery | Observation of patients exhaust on days after operation |
| the time of first defecation | one month after surgery | Observation of patients bowl movement on days after operation |
| the time of first oral feeding | one month after surgery | Observation of patients oral intake on days after operation |
| anastomotic orifice stricture and torsion | one month after surgery | According to results of intestinal barium contrast, colonoscopy and clinical symptoms to judgment |
| the incision length and cosmetic | one month after surgery | Comparing length and cosmetic of two groups measuring with metric |
| pain score | postoperative 6 hours, the first day and the third day | Estimate for pain of subject By Visual Analog Scale for Pain (VAS Pain，The scale is divided into four levels, with the minimum（1 score） and the maximum（10 score） level. The higher the level that more severe pain.) |
| postoperative hospitalization days | one month after surgery | Observation of patients hospitalization duration on days post-surgery |
