Case Discussion

Paralytic ileus is the failure of passage of enteric contents through the small and large bowel loops due to paralysis of intestinal motility and not a mechanical obstruction.

Some degree of ileus is an expected finding after abdominopelvic surgery and routine conventional recovery times have been reported up to 72 hours. Prolonged postoperative ileus for more than 72 hours has been termed "paralytic" ileus by some and operative difficulty, operation more than 3 hours, bowel handling, drop in hematocrit levels, the need of a transfusion, and lack of mobility after operation are common risk factors for a long-standing post-surgical ileus.

Sometimes a prolonged postoperative paralytic ileus is concerned for small bowel obstruction, bowel perforation, peritonitis, and intra-abdominal abscess and needs more evaluations.
