Plain English Summary

Background and study aims
Rectal cancer is treated with surgery to partially or totally remove the rectum along with the surrounding tissue containing blood vessels and lymph nodes. It is important to remove the local lymphatic system because it may contain cancer that has spread (metastases). Lymph nodes are found by the artery that supplies blood to the rectum. The extent of lymph node removal is determined by where the artery is tied (ligated) by the surgeon. Different surgeons remove more or less of the lymphatic system. There are usually two locations of arterial ligation, called “high tie” and “low tie”. The aim of our study is to find out whether the level of arterial ligation affects the incidence of complications after the operation and the patients’ long-term survival.

Who can participate?
Patients aged 18 or over undergoing surgery for rectal cancer

What does the study involve?
Participants are randomly allocated to one of two groups. One group undergoes high arterial ligation, and the other low arterial ligation. After hospital discharge participants are invited to routine follow-up visits every three months over the next 5 years. Participants should contact the department in case of any adverse symptoms or events. Quality of life, disease recurrence and complications are assessed.

What are the possible benefits and risk of participating?
There are neither direct benefits nor special risks of participating in the study since all of the proposed methods of the surgery are normally performed by different surgeons. Both methods of arterial ligation are recommended in rectal cancer treatment. Participation in the study will improve treatment for rectal cancer in the future by determining the best range of lymphatic system removal.

Where is the study run from?
Gdynia Centre of Oncology of Maritime Hospital in collaboration with the Medical University of Gdansk, Poland

When is the study starting and how long is expected to run for?
April 2011 to June 2019

Scientific title

Oncological and surgical outcome after high versus low ligation of inferior mesenteric artery during curative surgery from rectal cancer

Acronym

Study hypothesis

Oncological and surgical outcome after ligation and division of superior rectal artery just beneath the origin of left colic artery (low tie) is not inferior than after ligation of inferior mesenteric artery at its origin (high tie) during curative surgery for rectal cancer.
