Primary | Complication rate | Complication rate within 1 month postoperatively.All complications of surgery will be documented and graded by the Clavien-Dindo classification system,generally including anastomotic leakage, abdominal infection, bleeding, incision infection, incision implantation, intestinal obstruction, and rectovaginal fistula. | Up to 30 days postoperatively. | |
Secondary | C-reactive protein (CRP) | Detection of serum CRP levels (mg/L) to evaluate surgical stress response and immune function. | 1 day before operation, 1, 3, 5 days postoperatively, and up to 2 weeks. | |
Secondary | Interleukin | Detection of serum levels of Interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) (pg/L) to evaluate surgical stress response and immune function. | 1 day before operation, 1, 3, 5 days postoperatively, and up to 2 weeks. | |
Secondary | Cortisol | Detection of Serum Cortisol Level (nmol/L) to evaluate surgical stress response and immune function. | 1 day before operation, 1, 3, 5 days postoperatively, and up to 2 weeks. | |
Secondary | CD3, CD4, and CD8 lymphocyte subsets | Count CD3, CD4, and CD8 lymphocyte subsets (pieces/ul) to assess surgical stress response and immune function. | 1 day before operation, 1, 3, 5 days postoperatively, and up to 2 weeks. | |
Secondary | Positive rate of tumor cells | Intraoperative peritoneal lavage fluid will be collected both for aerobic culture and centrifuged ,stained and viewed to find exfoliated cancer cells.The sample will be considered positive if at least one tumor cell was detected. | Intraoperative. | |
Secondary | bacterial positive rate | Intraoperative peritoneal lavage fluid will be collected both for aerobic culture and centrifuged ,stained and viewed to find exfoliated cancer cells.The sample will be considered positive if at least one tumor cell was detected. | Intraoperative. | |
Secondary | Pain assessment | Visual analogue scale (VAS) will be used to evaluate the postoperative pain. If analgesics were needed, the type and dose of analgesics after operation should be recorded. | 1 day before operation, 1, 2, 3 days postoperatively, and up to 2 weeks. | |
Secondary | Wexner scale | Wexner scale (0 are normal continence, 20 are maximum incontinence with maximum disturbance of lifestyle) will be used to evaluate the defecation function. | 1 day before operation, and 1, 3, 6 months postoperatively. | |
Secondary | LARS scale | LARS scale(0~20 points are defined as no LARS, Scores from 21 to 29 were defined as mild LARS, and from 30 to 42 as severe LARS. The higher the score, the worse the anal bowel function) will be used to evaluate the defecation function. | 1 day before operation, and 1, 3, 6 months postoperatively. | |
Secondary | Postoperative recovery composite | Including the time to first flatus (record the patient's first self induced exhaust time after operation, accurate to hours, and perform auscultation of bowel sounds regularly every day after operation), the time to first ambulation (hours), the time to first eating (hours) and the time to first defecation (hours). | Up to 2 weeks. | |
