Richter's hernia at a Tenckhoff catheter exit site.

A 60-year-old male presented with a 2-day history of nausea, vomiting, and abdominal pain 3 months after kidney transplantation. No clinical and x-ray signs of small obstruction were present. A CT scan of the abdomen showed incarcerated small bowel loop at the site of the earlier peritoneal dialysis catheter (Tenckhoff) that was removed 2 months before.
