A NEW SURGICAL DEVICE FOR INTRAOPERATIVE RECTAL WASHOUT

CANCER CELLSColon CancerLOCAL RECURRENCERECTAL CANCERWASHOUT

Introduction

The anastomosis procedure in colorectal cancer can be followed by the formation of loco-regional recurrences by implanting into the mucosa of the carcinogenic cells.
Rectal intraoperative lavage has shown that these cells can be removed allowing a reduction of recurrence up to 40%, but modern minimally invasive surgical techniques do not allow intraoperative washing. The revolutionary forceps allows to perform an intraoperative wash and combines the benefits of minimally invasive surgery with the oncological benefits of washout.

Technical features

The instrument is a pincer-enterostat integrated into a mechanical stapler that allows iso-peristaltic lavage of the colon-rectum, below the lower pole of the neoplasm, before the colonic suture section. The washing allows to perform the subsequent surgical procedures in a perfectly decontaminated area of the intestine. The optimal direction of penetration of the washing fluid (in the oral-aboral sense), allows a more effective removal of the exfoliated cells compared to the known retrograde rectal washing techniques.
