This study determines the effect of chewing gum in the immediate postoperative period to facilitate ileus recovery following cholecystectomy. This is a randomized controlled trial in 2009. Twenty-four patients undergoing cholecystectomy and they divided in to two equal groups (n=12). Patients in group A chewed sugarless gum there time after surgery, each time 20 miniutes in 4, 10 and 18 hours after finishing sugery.

Data were analyzed using SPSS software version-13.5 and student t-test. The first bowel sound heard 3 ±1.3 and 2.8 ±1.3 hours post-operatively in cases and controls, respectively. The above findings were not significant between two groups. Furthermore gas passing reported at 18.3±10.5 and 36.28±12.6 hours post-operation in case and control groups respectively. The first defecation was occured at 36.8 ±21.7 and 69.5 ±19.2 hours after operation in case and control groups, respectively (p =0.001).
