Alvimopan addition to a standard perioperative recovery pathway.

BACKGROUND AND OBJECTIVES

Alvimopan, a peripherally acting mu-opioid receptor antagonist, decreased time to gastrointestinal recovery and hospital length of stay in open bowel resection patients in Phase 3 trials. However, the benefit in laparoscopic colectomy patients remains unclear.

METHODS

A retrospective case series review was performed to study addition of alvimopan to a well-established standard perioperative recovery pathway for elective laparoscopic colectomy. The main outcome measures were length of stay and incidence of charted postoperative ileus. Wilcoxon and chi-square tests were used to calculate P values for length of stay and postoperative ileus endpoints, respectively.

RESULTS

Demographic/baseline characteristics from the 101 alvimopan and 64 pre-alvimopan control patients were generally comparable. Mean length of stay in the alvimopan group was 1.55 days shorter (alvimopan, 2.81±0.95 days; control, 4.36±2.4 days; P<.0001). The proportion of patients with postoperative ileus was lower in the alvimopan group (alvimopan, 2%; control, 20%; P<.0001).

CONCLUSION

In this case series, addition of alvimopan to a standard perioperative recovery pathway decreased length of stay and incidence of postoperative ileus for elective uncomplicated laparoscopic colectomy. The improvement in the mean length of stay for patients who receive alvimopan is a step forward in achieving a fasttrack surgery model for elective laparoscopic colectomies.
