A Study on the Tolerability of Early Postoperative Feeding in Patients with Colorectal Cancer

ABSTRACT

BACKGROUND: Resolution of postoperative ileus has traditionally been the moment at which bowel function returns. The re-start of postoperative oral feeding usually occurs after that. Recently, many reports have been published on early postoperative feeding in patients operated on laparoscopically and even in patients receiving a laparotomy. The aim of this study was to scrutinize the validity of early postoperative feeding. METHODS: Fiftyfour colorectal cancer patients who had undergone radical resective surgery for cure were included in this study and were divided into two group. Group 1 included 32 patients who were fed in a traditional manner. Group 2 consisted of 22 patients who received a regular diet on the first postoperative day. The mean age was 62, the male-to-female ratio was 1.21. Thirteen tumor were located on the right side colon, 4 on the left side colon, 10 on the rectosigmoid, 27 on the rectum. Operative methods were 13 right hemicolectomies, 4 left hemicolectomies, 19 low anterior resections, and 18 abdominoperineal resections. The possible problems associated with early oral feeding were well understood by the patients and consents were obtained. Immediately after the operation, the nasogastric tube was removed in the operation room, and The time of complete recovery from anesthesia was 3 to 5 hours later. At that time, liquid drink was given; then, liquid food or blended food was allowed. RESULT: Early oral intake was tolerable in 14 patients out of 21 (67%); in 8 patients a nasogastric tube was reinserted due to severe nausea, vomiting, and/or abdominal distension. All those minor problems were resolved after reinsertion of the nasogastric tube and returning to the traditional method. In one patient, who had a received a low anterior resection, a serious complication, anastomatic leakage, developed. Early oral intake was not thought to be the exact cause of the leakage, but it made the problem more complicated. A huge amount of feces soiled the peritoneal cavity and the already dissected retroperitoneum. CONCLUSIONS: The tolerability of early postoperative oral intake was 67%. In the remainder of patients, all the minor problems except one, were relieved by simply returning to the traditional method. However, early postoperative oral intake should be used with caution for patients who experience difficulty with anastomosis or have an intraoperative technical breakdown and in whom the possibility of leakage exists.
