Study summary

The study is a prospective radonmized comparison between needlescopic adrenalectomy and conventional laparoscopic adrenalectomy for benign adrenal tumors less than 5 cm. The operative success rate, operative time, intraoperative blood loss, intraoperative or postoperative complication, postoperative pain, postoperative hospital stay, convalescence, and wound cosmesis were compared.

Read the detailed description

Needlescopic instruments, defined as those with a diameter of no more than 3 mm. They result in smaller incisions than conventional 5- to 12-mm instruments, and thus better cosmesis. It may further reduce postoperative pain, hospital stay, and recovery time.

All operations were performed with the lateral transperitoneal approach. A 12-mm port was created near the umbilicus for a 30-degree telescope, and another two(for left lesions) or three (for right lesions) 2-mm working ports (Tyco Healthcare, Norwalk, Connecticut, USA) were created along the ipsilateral subcostal region. Careful dissection was done with the use of a 2-mm hook or scissors electrocoagulator. The adrenal vein of the lesion side was isolated and controlled with a 2-mm mini-bipolar coagulation apparatus (Tyco Healthcare) for a long segment. The vein was then transected closer to the adrenal gland, leaving the coagulated stump at the renal vein or vena cava as long as possible, even when a short right adrenal vein was encountered. Then the adrenal gland with the tumor was dissected from its surrounding tissues after several tiny vessels were transected with the needlescopic instruments mentioned above. The specimen was put into a retrieval bag and removed through the umbilical port.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 11, 2008, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
