Whole bowel irrigation--an alternative to traditional bowel washout

The objective of this study was to determine whether or not whole bowel irrigation through oral route was a safe and acceptable alternative to traditional bowel washout per rectum in preparation for large bowel surgery. Out of a total of 114 patients, 32 had whole bowel irrigation, 71 had traditional washout and 11 had no bowel preparation. The irrigation involved approximately 12 litres of normal saline over an average period of 3 1/4 hours. The preparation of the colon by whole bowel irrigation was better as indicated by total absence of faeces and the cleanliness of the colon at operation. However, there was no significant difference in wound infection rate between the two groups although the severity of wound infection was lesser in the first group. There were no major complications like anastomotic breakdown, burst abdomen, abscess or fistula formation and septicaemia in this group. Based on this experience we believe that whole bowel irrigation is a good alternative method of bowel preparation. The advantages of this method are that it is short and rapid, avoiding prolonged pre-operative hospitalisation and is acceptable to most patients.
