A Richter's hernia can result in strangulation and necrosis in the absence of intestinal obstruction. It is a relatively rare but dangerous type of hernia.[1]

Richter's hernia have also been noted in laparoscopic port-sites, usually when the fascia is not closed for ports larger than 10mm. A high index of suspicion is required in the post operative period as this sinister problem can closely mimic more benign complications like port-site haematomas.[2][3]

Treatment is resection and anastomosis. Mortality increases with delay in surgical intervention.
