Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to challenge the existing clinical practice of employing laparoscopic cholecystectomy as the treatment for gallbladder dyskinesia by comparing it to a regimen of active non-surgical therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Willing and eligible patients will be enrolled into the trial and randomized to surgical vs non-surgical treatment following informed consent. The following information will be collected over the next 18 months: age,race, sex, baseline and follow-up quality of life quationnaire scores, a complete medical history, including co-morbid illnesses, medications and surgical history, and a complete assessment of symptoms, including disease specific symptoms against the Rome III criteria for functional gallbladder disorder. Patients randomized to surgery will be referred for immediate laparoscopic cholecystectomy. Patients in the non-surgical management group will be counseled on maintenance of a low-fat diet, and provided with a prescription for amitriptyline 25mg once daily.

Patients with persistent, non responsive symptoms that fail to respond to at least one week of administration of amitriptyline will be allowed to voluntarily, cross over into the surgically treated group.

After randomization, certain data collection points will be unique to the two groups. These are as follows and are in addition to the general data which will be collected from both groups:

Surgery group: operative/pathology findings \& operative complications

Non-surgical group:

Patients will be asked to maintain a food diary and a symptom diary. Patients will be asked to report any medication related side effects.

Both groups will receive a phone call for assessment of conditions. Non-surgical groups will be asked to report any medication related side effects.

Follow-up for both groups will continue throughout the 18 month period. In addition to the monthly calls, Patients will be contacted every three months after their initial treatment to take the SF-8 questionnaire and obtain an assessment of symptoms using the Rome III criteria.
