There are severel problems associated with the closing of a temporary loop-ileostomy after surgery for rectal cancer. The purpose of this study is to answer two questions:

1. The choice of anastomotic method - does it influence the postoperative course?
2. The use of a prophylactic mesh when closing the stoma site - will there be less hernias?

Postoperative complications after closure of a temporary loop ileostomy after rectal cancer surgery are common. In this study the investigators propose the hypothesis that a stapled anastomotic technique will decrease postoperative small bowel obstruction and a mesh closure of the stoma site in the abdominal wall will decrease hernia formation.

All patients will be randomized to stapled or hand-sewn anastomosis. The randomization to mesh or suture closure of the abdominal wall is optional.

The stapled anastomotic technique is performed by the use of a linear staple device and the hand-sewn technique with a running seromuscular monofilament suture.

The stoma site has two options and will be closed either by the use of mesh (lightweight), positioned under the muscle (retromuscular), or just by long-lasting suture. The anterior fascia of the rectus as well as the skin are closed by the use of running monofilament longlasting sutures, the latter in a pursestring procedure.

Inclusion Criteria:

• loop ileostomy after rectal cancer surgery
• loop ileostomy closure is permitted and possible according to clinical practice

Exclusion Criteria:

• patient unable to understand written or oral information
