Indications for Gallbladder Surgery in Gallstone Disease

August 26, 2010 updated by: Haraldsplass Deaconess Hospital
The aim of the study is to identify patients with gallstone disease that should be operated and those that may potentially be observed. This selection was based on symptoms and clinical presentation. The consequences that may arise for the patient if observation is chosen compared with outcome after cholecystectomy has been markers of outcome.

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.

Detailed Description

  1. Randomized clinical trial (RCT) of observation versus surgery for uncomplicated gallstone disease
  2. RCT of observation versus operation for acute cholecystitis
  3. Study of outcome after cholecystectomy in patients from 1. and 2.
  4. Study of symptoms in gallstone disease and symptom relief after cholecystectomy
  5. Long-term morbidity and mortality, including cancer, after cholecystectomy
  6. Long-term follow-up of patients with silent gallstones

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 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients admitted to a hospital for either acute cholecystitis or uncomplicated symptomatic gallstone disease randomized to observation or operation. Patients from a population screening study for gallstones performed in 1983. Patients operated for gallstone disease in 1983.

Description

Inclusion criteria:

  • Symptomatic gallstone disease (SGBS):

Episodes of pain in the right subcostal or midline epigastric area lasting more than 30 min, with ultrasonography signs of gallstones.

  • Ultrasonographic: echo with an acoustic shadow in a visible gallbladder, or an echo with positional change and size <3 mm or, alternatively no demonstrable gallbladder but a strong echo with an acoustic shadow in the position of the gallbladder

Exclusion Criteria SGBS:

  • Infrequent and/or minimal pain that need only very occasional medication
  • Age below 18 or above 80
  • Not willing to participate

Inclusion criteria, acute cholecystitis (AC):

  • Acute abdominal pain
  • Duration of more than 8-12 h
  • Tenderness on clinical examination in the upper right quadrant
  • Presence of gallbladder stones and signs of inflammation on ultrasonography and in clinical biochemistry data, including an elevated temperature

Exclusion criteria, AC:

  • Severe concomitant disease
  • Suspected Common Bile Duct stone
  • Acalculous cholecystitis
  • Localized peritonitis suggesting gallbladder perforation or gangrenous cholecystitis

Inclusion criteria 1983 cohort of patients:

  • Participation in a screening study for gallstones in 1983
  • Operated for symptomatic gallstone disease in Bergen, Norway in 1983

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.

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.
