Introduction:

In current clinical practice, immediate coloanal anastomosis (ICA) remains the standard technique for restoring the gastrointestinal tract following coloproctectomy for low rectal cancer. This anastomosis still requires a temporary diverting stoma to decrease the postoperative morbidity, which remains significantly high. As an alternative, some authors have proposed a two-stage delayed coloanal anastomosis (TS-DCA). This article reports on the surgical technique of TS-DCA.

Methods:

The case described is of a 53-year-old woman, without any particular history, in whom colonoscopy motivated by rectal bleeding revealed an adenocarcinoma of the low rectum. Magnetic resonance imaging showed a tumor ~ 1 cm above the puborectalis muscle, graded cT3N +. The extension workup was negative. Seven weeks after chemoradiotherapy, a coloproctectomy with total mesorectal excision (TME) was performed. A TS-DCA was chosen to restore the digestive tract.

Conclusion:

Two-stage delayed coloanal anastomosis is a safe and effective alternative for restoring the digestive tract after proctectomy for low rectal cancer. Recent data seem to show a clear advantage of this technique in terms of morbidity. (AU)
