Abstract

A method and device for preventing or treating parastomal hernia is provided. The method can include positioning a graft material between a rectus sheath and a rectus abdominus muscle surrounding a stoma.

Claims (28)

1. A method of preventing parastomal hernia, comprising:

selecting a graft material for reinforcement of a stoma site;

forming an opening in an abdominal wall traversing the rectus abdominus;

dissecting a space between the rectus abdominus muscle and a rectus sheath of the abdominal wall surrounding the opening;

inserting the graft material into the space between the rectus abdominus muscle and the rectus sheath;

passing a portion of a hollow organ through the graft material and the opening in the abdominal wall to form a stoma between the hollow organ and the abdominal wall with the graft material surrounding the hollow organ; and

attaching a portion of the hollow organ to the abdominal wall to produce an ostomy, the graft material is not actively fixed to the rectus abdominus muscle or the rectus sheath.

2. The method of claim 1 , wherein the space is formed between a posterior rectus sheath and the rectus abdominus muscle.

3. The method of claim 1 , wherein the space is formed between an anterior rectus sheath and the rectus abdominus muscle.

4. The method of claim 1 , wherein the space is formed between an anterior rectus sheath and the rectus abdominus muscle and a posterior rectus sheath and the rectus abdominus muscle, and wherein a first graft material is inserted into the space between the anterior rectus sheath and the rectus abdominus muscle and a second graft material is inserted into the space between the posterior rectus sheath and the rectus abdominus muscle.

5. The method of claim 1 , wherein the graft material is non-synthetic.

6. The method of claim 1 , wherein the graft material is an acellular tissue matrix.

7. The method of claim 6 , wherein the graft material is a dermal matrix.

8. The method of claim 1 , wherein the graft material is inserted into the space through the opening in the abdominal wall.

9. A method of repairing a parastomal hernia, comprising:

selecting a graft material for reinforcement of a stoma site;

dissecting a space between the rectus abdominus muscle and the rectus sheath of the abdominal wall surrounding a stoma site;

inserting the graft material into the space between the rectus abdominus muscle and the rectus sheath to surround the stoma site;

wherein the graft material is not actively fixed to the rectus abdominus muscle or the rectus sheath.

10. The method of claim 9 , wherein the space is formed between a posterior rectus sheath and the rectus abdominus muscle.

11. The method of claim 9 , wherein the space is formed between an anterior rectus sheath and the rectus abdominus muscle.

12. The method of claim 9 , wherein the space is formed between an anterior rectus sheath and the rectus abdominus muscle and a posterior rectus sheath and the rectus abdominus muscle, and wherein a first graft material is inserted into the space between the anterior rectus sheath and the rectus abdominus muscle and a second graft material is inserted into the space between the posterior rectus sheath and the rectus abdominus muscle.

13. The method of claim 9 , wherein the graft material is non-synthetic.

14. The method of claim 9 , wherein the graft material is an acellular tissue matrix.

15. The method of claim 14 , wherein the graft material is a dermal matrix.

16. The method of claim 9 , further including detaching the stoma from the abdominal wall before inserting the graft material into the space between the rectus abdominus muscle and the rectus sheath to surround the stoma site;

passing a portion of a hollow organ forming the stoma through the graft material and an opening in the abdominal wall to reform a stoma between the hollow organ and the abdominal wall with the graft material surrounding the hollow organ; and

attaching a portion of the hollow organ to the abdominal wall to produce an ostomy.
