[Delayed healing of colonic anastomoses after tumour resection (author's transl)]

Local tumour recurrences at colonic anastomoses in an early, curable stage are rarely missed by double contrast enema. On the other hand, the variable appearances caused by inflammatory lesions, which delay healing of the anastomosis, are often misinterpreted as recurrences. Early post-operative investigation with a water-soluble contrast medium is therefore important. Small and transient leaks at the suture line may cause intramural inflammatory lesions with a variety of symptoms and may be confused with local recurrences. They are due to delayed healing at the anastomosis and will only be interpreted correctly if there is regular radiological follow-up.
