Randomized Study Comparing Two Established Gastrointestinal Suture Techniques - One-layer-continuous Versus Double-layer-continuous Suture

Randomized Trial to Compare Two Gastrointestinal Anastomosis Techniques - Single Layer Continuous Versus Double Layer Continuous

The purpose of this study is to examine the frequency of postoperative complications depending on the number of suture layers in colo-colonic and ileo-colonic anastomoses Hypothesis: double-layer suture has less anastomotic leakages compared to single-layer suture.

Inclusion Criteria:

• at least 18 years old,
• planned for elective surgery
• at least one hand-sutured ileo-colonic or colo-colonic anastomosis

Exclusion Criteria:

• ASA-Score > 3,
• missing written consent of the informed patient
• no existing choice between suture-techniques according to the surgeon
• patient not able to cooperate/non-compliance
• rectal anastomoses
