Complications of rectal anastomoses with end-to-end anastomosis (EEA) stapling instrument. Clinical and radiological leak rates and some practical hints.

The complications and results of rectal anastomoses carried out with the end-to-end anastomosis (EEA) stapling instrument on 50 patients by 5 consultant surgeons are recorded. There was a clinical leakage rate of 6% and a radiological leakage rate of 20% assessed by water-soluble contrast enema. The technique has advantages compared with hand-suture by allowing low anastomoses and preservation of sphincters and is accompanied by an acceptably low leakage rate. Despite the cost of disposable cartridges these advantages make the technique economical because of the avoidance of colostomies and reduction in hospital stay.
