Study summary

Laparoscopic anterior resection is a standardized procedure requiring a small muscle split incision to retrieve the specimen and to fashion the proximal part of the double stapled anastomosis. Most patients can be included within a standardized perioperative care program called Enhanced Recovery After Surgery (ERAS). A new evolution as a primary step towards a complete Natural Orifice Translumenal Endoscopic Surgery (NOTES)-procedure is a hybrid approach (transrectal and laparoscopic). The dissection is performed laparoscopically but the specimen is retrieved within an endobag through the rectum. The anastomosis is created intracorporeally using a triple stapled technique. There are no trials available in the literature concerning these 2 techniques. Therefore this study will be undertaken to establish the role of the 2 surgical procedures and to compare them after short-term follow-up.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The record gives a start of Dec 2009, a primary completion of Dec 2011 and a completion of Jun 2025. It does not say whether these dates are actual or estimated.

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 1, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
