LOPEZ-KOSTNER, Francisco et al. Impact of anastomotic leak in colorectal surgery. Rev Chil Cir [online]. 2016, vol.68, n.6, pp.417-421. ISSN 0718-4026.  http://dx.doi.org/10.1016/j.rchic.2016.05.009.

Introduction: Anastomotic leak is the most important complication on colorectal surgery. Objective: Analyze the frequency and impact of anastomotic leaks in laparoscopic colorectal surgery. Material and methods: Longitudinal study of prospective database of patients undergoing colorectal surgery between July 2007 and August 2014. Results: 654 patients operated, 52.3% were men with an average age of 57 years (42-72). The most frequent indication was colorectal cancer in 244 patients, 159 (24.3%) operated for colon cancer and 85 (12.9%) for rectal cancer followed by diverticular disease in 239 patients (36.5%) and 171 patients (26.1%) with other diagnoses. In 44 patients (6.7%) anastomotic leakage was observed with a median of 4 days post surgery for diagnosis. As factors associated with filtration, we identified male gender, anesthesic risk according to ASA, need for conversion to laparotomy and ileoanal anastomosis. With regard to treatment, 15 (33.7%) were successfully treated with medical therapy alone and 29 required re-intervention, of which 23 (79.3%) required an ostomy protection. There was no mortality associated with surgery and average LOS was 12 vs. 5 days in patients with filtration compared with patients without anastomotic leakeage. Conclusion: This serie helps to identify patients groups with increased risk of anastomotic leakage who double their hospital LOS and in a higher percentage should need re-intervention. Suspicion and early diagnosis reduces morbidity and mortality.
