Hello, Failure to regain normal bowel movements after abdominal surgery depends on several associated things like prior fluid and electrolyte balance, duration of the surgery, intra-operative and post-operative developments etc. Management is usually done by observation, maintenance of fluid and electrolyte balance, prevention of possible infection through prophylactic antibiotics, passage of a flatus tube to relieve pain due to gaseous distension and so on. There are no known long term risks as the condition usually is temporary. Hope this helps.
