Minimally Invasive Versus Open Surgery for PHC

May 30, 2022 updated by: Renyi Qin

Minimally Invasive Versus Open Surgery for Perihilar Cholangiocarcinoma(PHC)：A Multicenter Real-world Study

Brief Summary: This is a multicentric, retrospective, real-world study to investigate the surgical outcomes of minimally invasive surgery compared with open surgery for Perihilar Cholangiocarcinoma (PHC), with the perioperative characteristics and long-term overall survival being compared. We aimed to find out whether the minimally invasive surgery is safe or feasible for PHC. And we also want to find out patients with what kind of characteristic can be benefit from the minimally invasive surgery compared with the open approach.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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.

Study Population

A retrospective review of a real-world institutional databases from 10 hospitals in China identified PHC patients who underwent curative LS or OP surgery (including R0 and R1) form January 2012 and January 2019.Patients with pathologically confirmed PHC and without any evidence of distant metastasis by preoperative examinations were included.

Description

Inclusion Criteria:

Histologically confirmed PHC.

Exclusion Criteria:

  1. Peritoneal seeding or metastasis to the liver, para-aortic lymph nodes, or distant sites;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Postoperative length of stay
Time Frame: up to 90 days
defined as the time from being admitted to hospital to discharge
up to 90 days
Overall survival
Time Frame: through study completion, an average of 5 year
defined as the duration from the first day after surgery to either the date of death or the last follow-up
through study completion, an average of 5 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Operation time
Time Frame: intraoperative
defined as the time from skin incision or trocar placement to complete skin closure
intraoperative
Reoperation within 90 days
Time Frame: up to 90 days
defined as any reoperation within 90 days
up to 90 days
Mortality
Time Frame: up to 90 days
defined as any death within 30 days and 90 days, respectively
up to 90 days
Readmission within 90 days
Time Frame: up to 90 days
defined as any readmission within 90 days
up to 90 days
Intraoperative blood loss
Time Frame: intraoperative
recorded by the anesthetist using a vacuum system
intraoperative
postoperative complications
Time Frame: up to 90 days
Postoperative complications were reviewed within 90 days after surgery and graded according to Clavien-Dindo (CD) classification system.Postoperative biliary leakage, hemorrhage, and liver failure were defined and classified according to the criteria set out by the International Study Group of Liver Surgery (ISGLS). Wound infection was defined as purulent drainage from the incision or/and positive findings of culture of the fluid or tissue aseptically obtained from the incision.
up to 90 days
Operative details
Time Frame: intraoperative
including blood transfusion, vascular resection, number of resected lymph nodes
intraoperative
R0 resection
Time Frame: intraoperative
defined as tumor-free margins in all the reported surgical margins (biliary and circumferential margins)
intraoperative
Vessel reconstruction
Time Frame: intraoperative
defined as any repair or replacement of major vessels during surgery
intraoperative

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
