About this study

Official title: Randomized Controlled Trial Between PRA(Posterior Retroperitoneoscopic Adrenalectomy) and LA(Laparoscopic Adrenalectomy)

The purpose of this study is to compare two surgical methods of adrenalectomy. One is called PRA(posterior retroperitoneal adrenalectomy), which is performed through 3 or 4 holes at patient's back. The other is LA(laparoscopic adrenalectomy) which is performed through patient's abdominal cavity after making 3 or 4 holes in the abdomen.

Read the detailed description

Since 1992, transabdominal LA(laparoscopic adrenalectomy) has been a standard method of adrenalectomy. This traditional method has been used widely because this procedure provides wide view of the whole abdomen which is familiar to surgeons. But due to its unique location at retroperitoneum, adrenal is still not easy to approach. So various retroperitoneal approaches were designed and adjusted. Among those, PRA(posterior retroperitoneal adrenalectomy) has showed good outcomes in many institutes. PRA facilitates direct approach to kidney and adrenal gland, and so operative time can be shortened. But there has been no randomized controlled trial between these two methods.

Therefore, as experienced surgeons in both methods, we want to practice this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Operation time

    operation time will be measured by attending nerse

    Measured: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks

Secondary outcomes (5)
  1. Pain sensation after surgery

    Pain score will be described daily during hospitalization, and also at out patient clinic after discharge

    Measured: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks

  2. Recovery of bowel movement

    Gas out is regarded as a recovery of bowel movement

    Measured: Participants will be followed the duration of hospital stay, an expected average of 5 days

  3. Wound complication

    Measured: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks

  4. Blood loss during operation

    Measured: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks

  5. Intra-operative hemodynamic status

    Events as below will be recorded and compared severe hypertension(systolic BP>200mmHg), severe hypotension(systolic BP<90mmHg), Tachycardia(HR>110/min), Bradycardia(HR<50/min)

    Measured: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks

Questions about this trial

What is this clinical trial studying?

A study testing PRA and LA in people with Adrenal Disease, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Operation time (time frame: Participants will be followed until the first visit of out patients clinic after discharge, an expected average of 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01676025, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2017.
