Study summary

Laparoscopic right hemicolectomy (LRH) is an accepted surgical procedure for several right sided colonic pathologies. Recently the advantages of the intracorporeal ileotransversostomy over the extracorporeal anastomosis is appearing in the literature. Additionally, specimen extraction through the natural orifices is an emerging method when combined with the totally laparoscopic procedures. Our observations on natural orifice surgery was promising . In our daily surgical practice, investigators prefer the intracorporeal anastomosis and this study was conducted to compare the specimen extraction sites after LRH. Here investigators aimed to compare the results of conventional and natural orifice specimen extractions (NOSE) after totally LRHs.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2013 to primary completion in Mar 2019, 74 months.

Of 99 non-industry interventional studies with no phase under Surgical Wound, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 53. This study's 74 months is above that.

Counting every sponsor, half of 126 studies reached it within 18 months; a quarter within 9 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

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 Oct 14, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
