Introduction: Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay. Post-operative ileus (POI) is an important reason for remaining patients not permit oral (NPO) in post-operative period. The tradition was that when patients passed flatus, they were ready to consume a liquid diet, and then a solid food diet was gradually introduced. This approach was taken to avoid aspiration, gastric and intestinal distension, and anastomotic dehiscence. Although studies demonstrated that the conventional strict feeding regimens were not necessary, many surgeons still hesitated to allow early oral feeding. There has been concern that early oral intake would result in vomiting and severe paralytic ileus with subsequent aspiration pneumonia, wound dehiscence and anastomotic leakage. This belief has become surgical dogma, unsupported by scientific evidence. Aim: to investigates the effect of early oral postoperative carbohydrates feeding on postoperative outcome. Material and methods: forty abdominal surgery patients were randomly assigned to early oral postoperative feeding group (20) or traditional feeding group (20). In the early feeding group (study group), patients were initially started on clear fluid only 16 h after surgery and progressed to liquids (after 24 h) and then soft and regular diet in next day (after 48 h). In the post-operative period, the patients were visited each 12 h and clinical signs and symptoms such as, time of passed flatus and moved their bowels, nausea and vomiting, and the length hospital stay were assessed. Conclusions: This study showed that early oral postoperative carbohydrates feeding group passed flatus and moved their bowels much sooner than the control group thus reducing the duration of POI and hospital stay, but there is no increase in occurrence of of nausea and vomiting between tow groups.
