Anastomotic leakage leads to increase the rate of secondary interventions, re-operations, longer postoperative hospital stay, increased cost, and major impact on the patient's quality of life. In the medium to long term, patient may be unfit for post-operative adjuvant therapy with decreased the disease survival. Furthermore anastomotic leakage itself may increase the local recurrence, a reduction in overall survival, and a large proportion of patients are left with a permanent stoma.
