Perioperative use of statins in elective colectomy

Statins have many beneficial effects and may attenuate the proinflammatory and metabolic stress response to surgery and consequently reduce postoperative morbidity.

This study investigated whether perioperative use of statins improved short-term outcomes after elective colectomy.

This study is a retrospective review of prospectively collected data.

This study was conducted in consecutive patients undergoing elective colonic resection within an enhanced recovery program at a tertiary hospital (Manukau Surgery Centre, Middlemore Hospital, Auckland, New Zealand) from January 2005 to December 2010.

Complications, hospital stay, and readmissions were recorded for 30 days postoperatively. Postoperative functional recovery was measured by the use of the validated Surgical Recovery Score. Serum proinflammatory cytokines were measured on postoperative day 1.

There were 269 patients; 86 patients were on a statin perioperatively, whereas 183 patients had no statin. Members of the statin group were older (median age, 72 vs 69 years; p = 0.021), included more men (53% vs 40%; p = 0.049), and included a higher number of patients with an ASA score of 3 (55% vs 22%; p < 0.001). Patients on statin therapy had a significantly lower number of anastomotic leaks (1% vs 7%; p = 0.031). However, there was no significant difference in total complications or median hospital stay. The 2 groups had comparable functional recovery, and there was no significant difference in serum cytokine levels.

This retrospective study did not analyze type, duration, or dose of statins given perioperatively.

Patients on perioperative statins had greater baseline perioperative risks compared with nonusers, but they achieved equivalent outcomes overall. Statin use was associated with reduced anastomotic leaks. Thus, perioperative statin use may reduce morbidity after elective colectomy, and this finding warrants further investigation.
