Following colostomy surgery, the intestinal contents are rerouted, and it can take time for the bowel to adjust to this new configuration. The presence of gas, often with an unpleasant odor, can be attributed to the bacterial fermentation of the food that the patient has eaten, which is now passing through the colostomy.

In the immediate postoperative period, the bowel may not yet be fully functioning, and gas production is generally a sign that some level of digestive and fermentative processes are resuming. However, it is important to monitor the situation to ensure that bowel function is returning to normal, but malodor alone, especially just two days after surgery, does not indicate a problem. Early signs of ischemic bowel typically present with other symptoms such as severe abdominal pain, distention, or changes in vital signs, which are not implied here.

Similarly, the presence of malodorous gas does not necessarily signify inadequate preoperative bowel preparation, as the odor can change based on diet and the time frame after surgery. Thus, the interpretation that malodorous flatus from a colostomy is a normal, expected
