Study summary

Since the first report of laparoscopic resection of a benign hepatic tumor by Professor H. Reith in 1991, the laparoscope has been widely used in liver disease. Based on its advantages in laparoscopic vision and amplification, laparoscopic hepatectomy (LH) has been well recognized globally. Generally speaking, for lesions located in the left, front or lower part of the liver, corresponding to Couinaud segments II, III, IVb, V and VI, an LH surgery is recommended; however, for lesions located in segments VII and VIII, the surgery is high technically difficult due to poor exposure. Therefore,the investigators employ the left lateral position plus jackknife position to better expose lesions in these segments, hoping to reduce surgical time and bleeding in LH.

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 Jun 22, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
