Long-term efficacy of endoscopic vacuum therapy for the treatment of colorectal anastomotic leaks.

BACKGROUND

Anastomotic leaks are a severe complication after colorectal surgery. We aimed to evaluate the long-term efficacy of endoscopic vacuum therapy for their treatment.

METHODS

Retrospective review of a series of post-surgical colorectal leaks treated with endoscopic vacuum therapy, with minimum follow-up of 1 year. Generalized peritonitis or haemodynamic instability was considered contraindication to endoscopic treatment.

RESULTS

Endoscopic vacuum therapy was applied in 14 patients with colorectal leak, in 2 cases complicated by recto-vaginal fistula. Overall success rate was 79%, favoured by early beginning of treatment (90%) and presence of a stoma (100%) and no preoperative radiotherapy (86%). Median duration of treatment was 12.5 sessions (range 4-40). Median time for complete healing was 40.5 days (range 8-114), for a median cost of treatment of 3125 Euros. No complication related to endoscopic vacuum therapy was observed. Further surgery was required in 3 cases.

CONCLUSION

Endoscopic vacuum therapy is a safe treatment for post-surgical leaks, with high success rates.
