- Injury to the intestine (especially in cases of severe adhesions → extensive, careful adhesiolysis). In cases of extensive or multiple injuries to the intestinal wall, a small bowel segment resection with new anastomosis should be performed.
- Bleeding (→ bloodless, careful surgery)
- If there is poor blood supply to the ends of the connection, an intraoperative resection must be performed.

Intraoperative complications and their prevention
-
Postoperative complications and their prevention
- Peritonitis due to anastomotic leakage or intraoperatively unrecognized injury to other intestinal sections with leakage of stool into the free abdominal cavity
- Fecal fistula
- Incisional hernia (→ possibly wearing an abdominal binder for 6 weeks)
- Postoperative ileus (→ possibly bowel-stimulating measures), caution indirect indication of anastomotic leakage!
- Postoperative stenosis of the anastomosis (→ good blood supply to the anastomosis, tension-free surgery; reoperation may be necessary in individual cases)
- Wound infections (→ adequate wound drainage "Gunsight!")
