Patient selection: colorectal surgery
Early bowel obstruction = bowel obstruction within 30 days of surgery
Factors associated with an increased risk for early bowel obstruction:
(1) Crohn's disease (OR 12.3)
(2) diverticulitis or diverticulosis (OR 1.5)
(3) malignant tumor (OR 1.8)
(4) emergency admission (OR 2.5)
Factors associated with a reduced risk for early bowel obstruction:
(1) total colectomy (OR 0.6)
(2) benign tumor resection (0.4)
where:
• The risk associated with diverticulitis/diverticulosis depends on the extent of inflammation present. A ruptured diverticular abscess should be associated with an increased risk for obstruction. This situation may be covered by the emergency category.
• A patient with a total colectomy would have less to obstruct.
• The extent of the malignant tumor would impact the risk of early obstruction. A small tumor in a polyp should have a low risk for obstruction.
• Penetrating trauma was listed as a variable in the tables.
