BACKGROUND
Anastomotic leaks after low anterior resection following rectal cancer is the major cause for morbidity and mortality. Various techniques for the conservative management of localised abscesses have been reported, but with variable results. Hence, in search of a new technique to treat anastomotic leak following low anterior resection, which is cost-effective and has good results.
MATERIALS AND METHODS
This study is a retrospective review of a prospectively maintained data of a novel technique to treat anastomotic leaks after low anterior resection with proximal diverting ileostomy in a single institution.
RESULTS
A total of 40 patients who underwent low anterior resection with diversion ileostomy for rectal cancer were studied. In them, 6 patients developed Grade B anastomotic leak, which were managed by this novel technique of paediatric endoscopic-guided transanal drainage of anastomotic leak following low anterior resection with diversion ileostomy using a 3-way Foley catheter. All the patients responded well, thus leading to local control of the septic foci without the need for any further radiological intervention or a laparotomy. This lead to salvaging the anastomosis. Out of the 6 patients managed by this technique, one patient developed stricture, which was managed by CRE balloon dilatation. All patients underwent stoma closure after a median postoperative time of 7 months.
CONCLUSION
Under paediatric endoscopic guidance, transanal drainage of anastomotic leak with an abscess cavity using a 3-way Foley catheter after low anterior resection with double-staple technique prevents further disruption of the anastomosis and local irrigation leads to faster sepsis control thus avoiding the morbidity of relaparotomy. This technique being a bedside procedure is cost-effective and feasible. This leads to good salvage of anastomosis along with early stoma closure and good long-term functional results.
