Case contributed by Dirk Tromp
Diagnosis almost certain

Presentation

Abdominal pain.

Patient Data

Age: 60 years old
Gender: Female

Multiple anterior abdominal wall incisional hernias. Two loops of herniating small bowel, with one loop obstructed and not incarcerated, and another which is incarcerated but not obstructed - conforming to a Richter's hernia. 

Incidental horseshoe kidney with a left ureteric stent.

Case Discussion

Richter's hernias involve only one side of the bowel wall. These incarcerate more frequently than other types of hernias, however rarely obstruct due to lesser degree of impingement of the lumen.
