- Bleeding from the mesentery and hematoma formation in the mesentery. Here, the bleeding must be controlled with a further deep puncture. Subsequently, careful attention must be paid to whether the bowel ends to be anastomosed are still adequately perfused; if necessary, a re-resection must be performed.
- A massive contamination through stool leakage should be avoided as much as possible. For this, soft bowel clamps can be placed on the bowel ends, and a moist drape should be used.
- Bleeding from the staple line can be oversewn with a continuous suture or single button sutures.
- In case of thread breakage during anastomosis, the suture should either be reapplied anew or a new thread placed and knotted.
