Intracorporeal Versus Extracorporeal Anastomosis In Laparoscopic Right Colon Resection

2021年9月30日 更新者:Yonsei University

Intracorporeal Versus Extracorporeal Anastomosis In Laparoscopic Right Colon Resection: A Prospective Randomized Multi-center Clinical Trial

STUDY DESIGN This study is a prospective, randomized, multi-center study comparing intracorporeal versus extracorporeal anastomosis in performing laparoscopic right colectomy. The study subjects will be randomly assigned to 1. intracorporeal anastomosis (experimental group) 2. extracorporeal anastomosis (control group) with 1:1 manner. After surgery the subjects will be followed up at 1month, after then, every 3 month in total 3 years.

STUDY POPULATION

1. Screening A detailed review of the medical records will be performed to assess inclusion/exclusion criteria for all subjects who have been diagnosed with right colon tumor (malignant or benign) or benign disease (complicated diverticulitis and so on) that are subject to a right colectomy procedure.

All patients who are eligible, meet the inclusion and none of the exclusion criteria of this study, will be offered enrollment into the study at each site.

RISK ANALYSIS

  1. Potential risks All these procedures are in practice today and only surgeons competent in a technique shall be allowed to perform those surgeries. Therefore, there are no anticipated additional risks than would normally be encountered from these surgeries when they are performed for these patients.
  2. Potential benefits There may be some benefit due to having closer follow-up in the study.

QUALIFICATION OF PARTICIPATING SURGEONS

  1. Surgical procedure

    • Laparoscopic surgery: a surgical technique where operations are performed far from their target anatomy location through small incisions normally less than 15mm.
    • Extracorporeal anastomosis: the anastomosis is performed by pulling out the bowel through a laparotomy.
    • Intracorporeal anastomosis: the anastomosis is performed inside the abdominal cavity with a laparoscopic technique. Specimen extraction will be done through Pfannenstiel incision or similar incision in lower abdomen.
  2. Procedure standardization and qualification procedure Participating surgeons should complete the learning curve of the procedure and experience at least 50 laparoscopic right colectomy. They are required to be evaluated by the quality control (QC) committee. They should submit their unedited videos of laparoscopic right colectomy and must be accepted by 2 or more of total 3 QC committee members.

STATISTICAL ANALYSIS Based on attaining a success rate of 85% for the primary endpoint, a total of 106 subjects will be required for each group. Accounting for a 5% loss, a total of 241 subjects will be recruited for this study.

STUDY METHODS

  1. Ethical committee approval The study protocol, patient informed consent form and other required study documentation will be reviewed and approved by an institutional review board or any other authority body, prior to study start-up.
  2. Study duration and enrollment The total study duration will be approximately 5 years. Study enrollment will take approximately 24 months. The study subjects will have a short-term follow-up at 30 and 3 months post procedure, with long term follow-up upto 3 years after surgery. Surveillance will be performed according to standard follow-up guideline after colorectal cancer surgery.
  3. Randomization All the enrolled subject will be randomly assigned to one of the study group (intracorporeal or extracorporeal). The randomization will be performed upon the enrollment at the central institution stratifying center on 1:1 manner by a coordinator who is not aware of any clinical information
  4. Data collection Data will be collected at baseline, operative procedure, discharge, 1 month, 3 months and 1 year. A screening log will be maintained at each site during the enrollment period, in which all patients eligible for the trial shall be identified. This will be maintained to ensure no patient selection bias occurs within a center or by a surgeon.
  5. Informed Consent Using the study-specific, IRB approved, informed consent form, information pertinent to this study will be provided to the subjects in writing and in their native, non-technical, language. The consent form will include a description of the study and its purpose, potential benefits, potential risks, site contact information, and all other elements required of an informed consent.

    Subjects are required to voluntarily sign the informed consent form before any study-specific procedure is performed. The Investigator and/or his/her authorized designee, trained on the protocol and performing a consent, will conduct the informed consent process and will answer questions the subjects may have. If the subject agrees to participate, the informed consent form must be signed and dated by the subject or his/her legally authorized representative prior to enrollment in the study and separately signed and dated by the person taking consent. Only subjects who have signed the study informed consent will be included in the study.

  6. Withdrawal and discontinuation The subject's participation in any clinical trial is voluntary. The subject has the right to withdraw at any time without penalty or loss of benefit. Study withdrawal means the subject is no longer participating in the study and no further follow-ups will be performed. All subjects that withdraw after informed consent is signed will be evaluated at the time of withdrawal. Every effort will be made to document the subject outcome at the time of withdrawal. The investigator has the right to discontinue subjects from the study at their discretion to ensure wellbeing of the subject. The reasons for withdrawal shall be documented.
