title: Gallstone ileus.
abstract: Twenty patients with gallstone ileus were treated over a 20-year period. The demographics were typical: mean age 76, female to male ratio of 5:1, and 60 per cent incidence of concomitant medical ailments. An 85 per cent preoperative diagnostic rate was unusually high. An analysis of the study halves demonstrated a stable preoperative diagnostic rate, decrease in preoperative delay (7.5 vs. 4.7 days), and a rise in mortality rate (0 vs. 11%) without an unfavorable effect from a 26 per cent incidence of single-stage procedures (0% mortality). Gallstone ileus still carries a mortality rate of five to ten times that of all other nonmalignant mechanical small bowel obstructions. Anticipated improvements related to augmented preoperative diagnostic yields shortened preoperative delays, and selective surgical management have not been substantiated. Improved mortality rates may await refinements in resuscitation, monitoring, and surgical skills.
