- Brief Summary
To understand the current situation of the postoperative gastrointestinal dysfunction in patients with colorectal cancer effect a radical cure, and analyze the risk factors, and build the colorectal cancer radical surgery in patients with gastrointestinal dysfunction risk prediction nomogram model decision tree classification and regression tree model, through internal validation evaluation the performance of the two models in the modeling data set and dividing the postoperative gastrointestinal dysfunction risk level.Two risk prediction models were used to carry out external verification, evaluate the clinical practicability and effectiveness of the model, and provide reference for further promotion of the model.
- Detailed Description
Colorectal cancer is characterized by high morbidity and mortality. Surgical treatment is the main treatment for colorectal cancer. Surgery is the best treatment for long-term survival.
Surgery is a destructive operation, can lead to local tissue injury, physical barrier damage, causes the patient's body, and a series of metabolism, neuroendocrine and immune response, all of which can cause local inflammation or systemic inflammatory response, also leads to occurrence of related complications, such as abdominal and pelvic infection, fever, anastomotic infection and fistula, intestinal obstruction, etc., Thus increasing the risk of postoperative complications. The trauma and irritation of gastrointestinal tract caused postoperative gastrointestinal dysfunction.
The procedure of surgery is accompanied by anesthesia, and the anesthesia mode of gastrointestinal surgery is mainly general anesthesia. Opioid analgesics are one of the most important components of general anesthesia. The most common side effects of opioid analgesics include postoperative intestinal obstruction, nausea and vomiting, chills and urinary retention. The use of anesthetic drugs further aggravated the postoperative gastrointestinal dysfunction.
At the same time, laparoscopic surgery must establish pneumoperitoneum pressure. In recent years, studies have suggested that pneumoperitoneum pressure can lead to changes in the body's internal environment, resulting in a series of pathophysiological changes such as tissue ischemia, intestinal edema, and release of inflammatory factors in the gastrointestinal tract, resulting in dysfunction of gastrointestinal function.
All the above reasons lead to gastrointestinal dysfunction as the highest complication after radical resection of colorectal cancer.A review of previous literature shows that there is no predictive assessment tool for gastrointestinal dysfunction in patients after radical resection of colorectal cancer.Therefore, it is necessary to construct a risk prediction model for patients after radical resection of colorectal cancer, and to verify the clinical practicability of the model through external verification.

Group Intervention Description questionnaires assessed patient with colorectal cancer after surgery Questionnaires set Patients with colorectal cancer who had a radical resection surgery.
- Primary Outcome Measures
Name Time Method gastrointestinal dysfunction 3 days after surgery The gastrointestinal dysfunction will be assessed by 《Intake, Feeling nauseated, Emesis, Exam, and Duration of symptoms scoring system(I-FEED)》.The questionnaire consisted of 5 items.The scale contains five items, with the highest score of 3 and the lowest score of 0 for each item. Items include: tolerance to eating, presence of nausea, presence of vomiting, presence of bloating, duration of symptoms.A score of 6 or greater is a diagnosis of gastrointestinal dysfunction.
- Secondary Outcome Measures
Name Time Method BMI Baseline Weight/(Height)²
Smoking history Baseline Smoking history will be assessed by 《Patient General Data Collection Form》,described by "yes" or "not".If patient has smoking history, the form will record how many cigarettes are smoked per day.
Nutritional Risk Baseline It will be assessed by《European Nutritional Risk Screening 2002(NRS 2002)》.If the score ≥3, it indicates high nutritional risk.The scale contains three items, namely, disease severity, nutritional status, and age. Among them, the highest score of disease severity and nutritional status was 3 and the lowest score was 0. Age ≥70 years is one point.
Preoperative bowel preparation one day before surgery It will be assessed by 《Bristol stool form scale》.Divided into 7 types, type 1 stool is granular, difficult to discharge. Type 2 is salami, which is hard. Type 3 is a strip with a cracked surface. Type 4 is strip, smooth surface, soft texture, easy to discharge. Type 5 stools are clumpy and soft in texture. Type 6 is a mushy loose stool. Type 7 is watery stool.
Previous medication history Baseline Medications history will be assessed by 《Patient General Data Collection Form》,described by "History of use of chemotherapeutics" 、"History of use of opiates"、"History of use of antithrombotic drugs" or "not".
Previous operation history Baseline Previous operation history will be assessed by 《Patient General Data Collection Form》,described by "History of non-abdominal surgery" 、"History of colectomy surgery"、"History of rectotomy surgery"、"History of other abdominal surgery" or "none".
Patient Mobility in the hospital one day after surgery Patient Mobility l will be assessed by 《Inter-rater reliability of the Johns Hopkins Highest Level of Mobility Scale (JH-HLM)》.The maximum score of the scale is 8 points, 1 to 3 points means that only bed activities can be carried out, 4-5 points means that bedside activities can be carried out, and 6-8 points means that under-bed activities can be carried out. The higher the score, the higher the level of activity.
