Brief Summary

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

  • 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.
  • 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.

Outcome Measures

Primary Outcomes (1)

  • surgical site infection

    The efficacy of the anastomosis technique is defined as a lack of surgical site infection within 30 postoperative days. 1. Superficial surgical site infection 2. Deep surgical site infection

    within 30 postoperative days

Secondary Outcomes (8)

  • 3 year disease-free survival

    3 years

  • Tissue morphometry

    within 30 postoperative days

  • Incidence of incisional hernia within 1 year after surgery

    1 year

  • Postoperative pain score in visual analogue scale

    within 7 postoperative days

  • Length of postoperative hospital stay

    within 7 postoperative days

  • +3 more secondary outcomes

Study Arms (2)

Intracorporeal anastomosis

EXPERIMENTAL

In this group, 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.

Procedure: Intracorporeal anastomosis

Extracorporeal anastomosis

ACTIVE COMPARATOR

In this group, the anastomosis is performed by pulling out the bowel through a laparotomy.

Procedure: Extracorporeal anastomosis

Interventions

In this group, 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.

Intracorporeal anastomosis

In this group, the anastomosis is performed by pulling out the bowel through a laparotomy.

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years or older
  • Right colon tumor with indication for right colectomy (malignant disease).
  • Patients with adequate performance status (Eastern Cooperative Oncology Group Scale score of ≤2)

You may not qualify if:

  • Patient with a comorbid illness or condition that would preclude the use of surgery.
  • Patients with cT4b tumors.
  • Patients whose disease condition requires major simultaneous combined resection other than right colectomy (e.g. other intestinal resection, liver resection)
  • Patients unwilling to comply with all follow-up study requirements
  • Patient undergoing emergency procedures
  • Obstructive disease (but, possible to enroll after stent insertion resolving obstruction)
  • Impossible preoperative bowel preparation
  • Metastatic disease
  • Pregnant or suspected pregnancy
  • Complicated inflammatory bowel disease (Crohn´s Disease, Ulcerative Colitis, Intestinal tuberculosis, Behcet's disease, Undetermined inflammatory bowel disease) that combined with intraabdominal abscess or intestinal fistula
  • No Informed consent
