Dieta precoce em pacientes submetidos à ressecção colônica : estudo clínico randonizado

Abstract

Nutrition plays a key role in surgical patient care. Early oral feeding after colorectal resections is one of the many factors that contribute to enhance recovery after surgery, mainly impacting on postoperative ileus. The aim of this study was to evaluate the impact of early postoperative oral feeding in patients submitted to elective colorectal resection. Patients were randomly assigned to either a conventional postoperative dietary regimen(diet only after passage of flatus or stool) or a free diet on the first postoperative day (study group). Altogether 29 patients were enrolled in trial, 69% were women. Mean age and nutritional requirements were similar in both groups. Good nutritional status was showed in 86% of patient in the traditional care group versus 46% in the study group (p<0,05). There was no difference between groups in terns of procedures (laparotomy or laparoscopic resections). Median hospital stay was 5,0 days in the traditional group versus 3,0 days in the study group (p<0,05). Elimination of flatus was reported on the 2nd postoperative day inthe traditional group versus on the first, in the study group. Complication rates and acceptance of diet were similar in both groups. Diarrhea occurred more frequently in the traditional group (OR=1,86; IC95%:1,08-3,20) In conclusion, early oral intake is well tolerated, leads to a significant decreased hospital stay and no increase in complications.
