While it is clear that in certain cases simple mechanical obstruction of the small bowel can be treated successfully without recourse to surgery, the management of obstruction of the small bowel by decompression is not without danger, especially when the exact nature of the lesion has not been ascertained. In certain instances of diagnostic uncertainty, suction decompression of the bowel postpones the inevitable train of events and creates a false sense of security.
