Technical Feasibility of Routine Intraoperative Cholangiography During Elective Rigid-hybrid Transvaginal Natural Orifice Transluminal Endoscopic Cholecystectomy

April 28, 2013 updated by: Daniel Steinemann, MD, Cantonal Hosptal, Baselland

An Open Case Series About Technical Feasibility of Routine Intraoperative Cholangiography (IOC) During Elective Rigid-hybrid Transvaginal Natural Orifice Transluminal Endoscopic Cholecystectomy (tvNCC)

While gold standard in the treatment of symptomatic gall stones is laparoscopic cholecystectomy with instruments introduced through multiple abdominal wall incisions, transvaginal access to the peritoneal cavity offers an alternative avoiding injury of the abdominal wall. Transvaginal hybrid-NOTES cholecystectomy has been demonstrated effective and safe. However it has not been demonstrated up-to-date if intraoperative cholangiography is feasible during such procedure. This observational case series describes success and technical feasibility of intraoperative cholangiography during transvaginal cholecystectomy. The investigators hypothesis is that cholangiography is feasible equal to conventional laparoscopic cholecystectomy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Women with gallstones
30 women with symptomatic gallstone disease with an indication for elective cholecystectomy
Procedure: Cholangiography during transvaginal rigid-hybdrid NOTES cholecystectomy
During transvaginal rigid-hybrid NOTES cholecystectomy a intraoperative cholangiography is performed. After dissection of the Calot's triangle and distal clipping of the cystic duct, the cystic duct is incised and a regular cholangiography catheter is inserted. Contrast is injected and an image is obtained using an image-converter. After extraction of the catheter the cystic duct is clipped proximally. This intervention is performed in all patients included in the study.

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
Number of patients with successful introduction of cholangiography catheter into cystic duct (yes/no)
Time Frame: intraoperative
Was the introduction of the cholangiography catheter into the cystic duct successfull during transvaginal rigid-hybrid cholecystectomy.
intraoperative

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
Time required for cholangiography
Time Frame: intraoperative
From incision of the cystic duct to clipping of the cystic duct
intraoperative
Intraoperative complications
Time Frame: intraoperative
intraoperative
postoperative complications
Time Frame: within 6 weeks from surgery
within 6 weeks from surgery

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

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.
April 1, 2012

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.
