Detection of Postoperative Intestinal Ischemia in Small Bowel Transplants

الملخص EN

Small bowel transplantation is acknowledged as auto- and allotransplantation.

In both instances, there is up to a 4%–10% risk of postoperative ischemia, and as the small bowel is extremely susceptible to ischemia, the timely diagnosis of ischemia is important.

The location of the transplant, whether it is buried in the abdominal cavity or in the neck region, increases the challenge, as monitoring becomes more difficult and the consequences of neglect more dangerous.

All methods for the early detection of postoperative ischemia in small bowel transplants are described together with the requirements of the ideal monitoring method.

A small bowel transplant can be inspected directly or indirectly; the blood flow can be monitored by Doppler or by photoplethysmography, and the consequences of the blood flow can be monitored.

The ideal monitoring method should be reliable, fast, minimally invasive, safe, objective, easy, cheap, and comfortable.

No monitoring methods today fulfill the criteria of the ideal monitoring method, and evidence-based guidelines regarding postoperative monitoring cannot be made.

The choice of whether to implement monitoring of ischemia—and if so, which method to choose—has to be made by the individual surgeon or center.
