Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Our study is a single arm, single center clinical trial. The enrolled patients will accept laparoscopic ileocecus-sparing right hemicolectomy. The primary endpoint: postoperative complications, 1-year local recurrence. The second endpoint: conversion to conventional right hemicolectomy, time to first flatus after surgery, number of harvested lymph nodes, 3-year disease free survival, R0 resection, Specimen morphometry

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: LISRH group
Following the principle of complete mesocolic excision(CME), Ileocecus-Sparing Right colectomy refers to the resection of the most portion of the ascending colon, hepatic flexure and mid to distal transverse colon. The extent of lymph node dissection and length of distal resection margin are similar to conventional right hemicolectomy. The length of proximal resection margin varies.
Procedure: laparoscopic ileocecus-sparing right hemicolectomy
The ileocecal artery(ICA) is skeletonized. The colic branch of ICA is divided and ligated. Preserve anterior cecal artery, posterior cecal artery and ileocecal branch of ICA. Divide and ligate the right colic artery(RCA) and middle colic artery(MCA) at their roots. Dissect the lymph nodes surrounding the ICA, RCA and MCA accordingly. Head-to-Head colocolic anastomois is done, with circular stapler via making an opening at the bottom of cecum.

Primary Outcome Measures

Primary Outcome Measures
