Conditions

Gastrointestinal neoplasms and neoplasm-like lesions (including gastric, duodenal, and colorectal lesions), with a focus on high-risk and complex gastrointestinal lesions.

Interventions

Gastric cohort:Combined endoscopic–laparoscopic surgery for gastric lesions
Colorectal cohort:Combined endoscopic–laparoscopic surgery for colorectal lesions
Duodenal cohort:Combined endoscopic–laparoscopic surgery for duodenal lesions

Eligibility

Age
18 Years to 80 Years

Inclusion criteria

Inclusion criteria: 1.Age 18–80 years, regardless of sex. 2.Diagnosed with gastrointestinal neoplasms or neoplasm-like lesions, and scheduled by the operator for dual-endoscopy minimally invasive treatment. Cases are considered “high-risk/complex” if conventional endoscopic treatment alone (e.g., EMR/ESD/EFTR) is expected to carry excessive risk or cannot be completed safely; 3.Lesions located in the stomach, duodenum, or colorectum. 4.Preoperative evaluation (endoscopic assessment with or without EUS/CT/MRI as appropriate) indicates localized disease without evidence of distant metastasis. 5.Considered fit to tolerate the planned procedure on anesthesia evaluation (ASA I–III or deemed feasible by the anesthesiology team). 6.Able to complete follow-up. 7.The subject or legally authorized representative voluntarily agrees to participate in the study and signs written informed consent.

Exclusion criteria

Exclusion criteria: 1.Definite or highly suspected advanced malignancy requiring standard radical resection and/or systematic lymph node dissection. 2.Imaging evidence of distant metastasis, peritoneal dissemination, or multiple unresectable lesions. 3.Judged preoperatively to be amenable to conventional endoscopic treatment alone (e.g., EMR/ESD/conventional closure) without surgical collaboration, with acceptable anticipated complication risk. 4.Severe cardiac, pulmonary, hepatic, or renal dysfunction, or other conditions rendering the patient unable to tolerate anesthesia/surgery (e.g., ASA = IV or deemed unsuitable by the anesthesiology team). 5.Uncorrectable coagulation dysfunction. 6.Inability to discontinue anticoagulant/antiplatelet therapy according to standard requirements, with unacceptable bleeding risk on assessment. 7.Active severe infection or unstable general condition. 8.Pregnancy or lactation. 9.Inability to provide informed consent or to comply with study procedures/follow-up. 10.Any other condition judged by the investigators to make the patient unsuitable for participation.
