Colorectal anastomotic perforation secondary to acute ruptured appendicitis presenting as septic arthritis

Anastomotic leaks following abdominoperineal resection with rectal anastomosis become clinically significant in 2.9%-22% of cases. Local recurrence of cancer and local inflammation are the most common causes of these leaks . Colonic perforation presenting with suppurative involvement of the lower extremities has been previously reported. We describe herein the case of a colorectal anastomotic leak secondary to pathology-proved acute appendicitis presenting with suppurative necessitation causing right hip septic arthritis five years following lower anterior resection (LAR) for stage unspecified colorectal cancer. No similar case has been demonstrated in the surveyed literature.
