Table 3:

Adjusted Risk of 30-Day Adverse Events Following Ileal Pouch Anal Anastomosis Creation

Adverse Event	Delayed Pouch (ref: PTC)
Unplanned reoperation	0.42 (0.24–0.75)
Unplanned readmission	0.95 (0.77–1.16)
Major adverse eventa	0.72 (0.52–0.99)
Minor adverse eventb	0.48 (0.32–0.73)

Risk ratios after controlling for age, sex, race, BMI, smoking status, diabetes, preoperative albumin, and American Society of Anesthesiology class.

^aA major adverse event is defined as an organ space SSI, sepsis, septic shock, acute renal failure, stroke/cerebrovascular accident, myocardial infarction, cardiac arrest requiring cardiopulmonary resuscitation, time on ventilator greater than 48 hours, hospitalization greater than 30 days, or death.

^bA minor adverse event is defined as a wound disruption, deep incisional SSI, superficial SSI, urinary tract infection, pneumonia, deep venous thrombosis/thrombophlebitis requiring therapy, and pulmonary embolus.

PTC = pouch creation at the time of colectomy.
