The main questions it aims to answer are:\n\n1. Does non-dressing of postoperative wounds in gastrointestinal tumor surgery provide equivalent or better wound healing compared to traditional dressing techniques?\n2. Can non-dressing of postoperative wounds reduce patient pain and healthcare costs? Participants in this study, who are diagnosed with gastrointestinal tumors and undergoing surgery, will be randomly assigned to either the non-dressing group or the dressing group. The non-dressing group will have their surgical wounds left exposed after initial postoperative care, while the dressing group will receive regular wound dressing changes every 48-72 hours. Researchers will compare these two groups to see if there are differences in the rate of wound complications, pain levels, and overall healthcare costs.\n\nThis study aims to provide evidence-based recommendations for postoperative wound care in gastrointestinal tumor surgeries, potentially improving patient outcomes and reducing medical expenses.', 'detailedDescription': "Research Objectives and Design:\n\nThis study is a prospective, randomized controlled trial primarily aimed at comparing the efficacy of wound healing between non-dressing and dressing methods post-gastrointestinal tumor surgery. The secondary objective is to evaluate the effectiveness of the non-dressing approach in reducing postoperative pain and medical expenses.\n\nInclusion Criteria and Sample Size:\n\nThe study plans to enroll 212 patients aged 75 years or younger, diagnosed pathologically with gastrointestinal tumors and scheduled for curative surgery or open gastrointestinal bypass surgery. Participants must have an ECOG (Eastern Cooperative Oncology Group) performance status score of 0/1 and be capable of understanding and signing the informed consent. Exclusion criteria include inability to complete postoperative follow-up, ineligibility for surgical treatment, concurrent skin diseases, history of abdominal trauma or surgery, other uncontrolled severe diseases, ongoing other cancer treatments, and current use of drugs that may affect wound healing.\n\nStudy Methodology:\n\nParticipants will be randomly assigned to one of two groups: a non-dressing group (Group A) and a dressing group (Group B). Group A will have dressings removed 48 hours post-surgery and keep the wound exposed unless signs of infection are present. Group B will undergo regular dressing changes every 48 to 72 hours until sutures are removed between the 7th and 14th postoperative days. Both groups will be closely monitored for wound treatment and complications such as fat liquefaction, infection, and wound dehiscence.\n\nWithdrawal/Early Termination Criteria:\n\nPatients may withdraw from the study voluntarily at any time. Researchers can also decide to withdraw a patient if continued treatment is deemed not in the patient's best interest. Reasons for withdrawal include but are not limited to other concurrent diseases, death, relapse, complications, receiving non-study treatments, or patient's request to exit the study.\n\nFollow-up Plan:\n\nThe study will conduct stringent follow-ups, including observation and assessment of the surgical wound 30 days post-surgery, recording the frequency of dressing changes, total costs, pain scores, and wound comfort levels. The follow-up endpoints include patient withdrawal, change in treatment modality, disease progression, death, or reaching the study's end date.\n\nObservation and Evaluation during the Trial:\n\nAll trial procedures must be preceded by obtaining informed consent approved by an ethical committee. All data collected during the trial will be statistically analyzed following the intention-to-treat principle."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
