Brief Summary in Scientific Language

We conduct an endoscopic control of the colorectal anastomosis after resection of the colon sigmoideum or rectum. The healing of the anastomosis will be graded with an endoscopic score.

Interventions/Observational Groups

  •   Patients that underwent a colorectal resection with creation of a colorectal anastomosis, with or without loop Ileoostomy that matched the inclusion criteria received a flexible rectoscopy on day 5.-8. after Surgery as a screening. The anastomosis receives a rating via a sore. A possibly following therapeutic intervention wasn't part of this Study.

Primary Outcome

successful and safe execution of an postoperative endoscopic Control of the anastomosis after a colorectal resection

end of 1:1-Block primary endpoint
start of 1:1-Block secondary endpoint

Secondary Outcome

- examination of anastomotic healing in regard to the different types of anastomis
examination of anastomotic healing related to the operation
- clinical relevance of an occult anastomotic leakage
- identification of clinical parameters enabling a prediction of the risk of an anstomotic leakage
- identification of criteria for the best timing of the operation
- application of a standardized score for the endoscopic evaluation of colorectal anastomosis
