Drain-site recurrence of an ileocaecal valve adenocarcinoma

Drain-site recurrence following colorectal cancer resection is a rare event and is described in few case reports. The majority of these reports are following minimally invasive surgery. This report describes a case of an isolated drain-site recurrence of primary colorectal cancer in a male patient in his 50s. He previously underwent an open right hemicolectomy and segmental small bowel resection for an obstructing ileocaecal valve adenocarcinoma. This was followed by adjuvant chemotherapy. Two years into surveillance, a redo ileocolic resection was performed for an anastomotic recurrence. While undergoing surveillance imaging, a new deposit was detected at a right-sided surgical drain site. Subsequently, a full thickness en bloc resection was performed. To date, the postoperative course has been uneventful. This case describes a drain-site recurrence from a colorectal primary.
