Ultimate fate of the leaking intestinal anastomosis: does leak mean permanent stoma?

Abstract

Background: The ultimate fate of the leaking intestinal anastomosis is unknown. We sought to analyze long-term outcomes of anastomotic leak with an emphasis on identifying the likelihood of re-establishing intestinal continuity and the potential for releak with corrective surgery.

Methods: All consecutive subjects treated for clinical anastomotic leak from January 2001 through December 2007 were retrospectively reviewed. Patients were stratified by management of leak: (1) drainage alone, (2) proximal loop diversion, (3) repair/revision without diversion, (4) end stoma, or (5) tube enterostomy. We then determined management of anastomotic leak, mortality, corrective procedures, releak, and re-establishment of intestinal continuity.

Results: In a database of 2,627 intestinal procedures, 79 patients had 88 anastomotic leaks with a final overall mortality of 10.1%. The aggregate rate of re-establishment of intestinal continuity was lowest for the patients treated by end stoma (44.4%) as compared to other initial management options (p < 0.01). Of the patients who survived their initial anastomotic leak, 20.5% had another leak (releak).

Conclusions: Patients who underwent resection of the leaking anastomosis and end stoma or proximal loop diversion have a high rate of long-term fecal diversion. The proportion of patients who experience an anastomotic releak is substantial following further corrective surgery to re-establish intestinal continuity.
