What Is the Meaning of an Early Anastomotic Recurrence after Curative Right Hemicolectomy? A Synchronous, Metachronous, or What Else?

In this paper we present a case of unexpected early local recurrence after surgery for colon cancer. Notably, an anastomotic recurrence was diagnosed two months after curative right hemicolectomy. Accurate preoperative endoscopic and radiological explorations were carried out, the resection was performed according to the oncological surgical principles, and the pathologic report confirmed the oncological radicality of the treatment performed. Therefore, the precocity of local recurrence appeared surprising, and led us to carry out a review of the literature in order to look into its possible explanations. The results of this research are presented.
