The Value of Early Postoperative Colonoscopy in The Early Diagnosis of Anastomotic Leakage After Surgery for Low Colorectal Cancer
Recruiting · Not Applicable · Nanchong Central Hospital · registry updated 2026-06-25
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
The goal of this clinical trial is to learn whether early postoperative colonoscopy is valuable in the early diagnosis of anastomotic leakage after surgery for low colorectal cancer.The main questions it aims to answer are: 1. Will the median diagnosis time of AL in the intervention group (early colonoscopy group) be significantly shorter than that in the control group? 2. Can targeted treatment (such as endoscopic vacuum therapy (EVT)) be initiated earlier in the early colonoscopy group, thereby reducing the incidence of AL and the rate of unplanned re-laparotomy? Researchers will compare the median diagnosis time of AL in the intervention group (early colonoscopy group) with the control group to observe whether early postoperative colonoscopy can detect anastomotic leakage earlier. Participants will: Experimental group (early colonoscopy group): 1. Colonoscopy will be performed on the 5th to 8th day after surgery (the surgeon will decide the specific date within this time window based on the patient's recovery). 2....
