Background:
Prolonged postoperative ileus (PPOI) is a common problem after major abdominal surgery and can cause postoperative morbidity, extended hospitalization, as well as increased health care costs.
Aim:
To investigate whether the levels of cytokines from abdominal exudate are predictive for early diagnosis of PPOI after colorectal surgery.
Methods:
One hundred patients who had undergone elective resection for carcinoma of the sigmoid or rectum were recruited. The abdominal exudate was obtained from a drain tube after surgery to examine the levels of C-reactive protein (CRP), procalcitonin (PCT), and tumor necrosis factor alpha (TNF-α). The relationship between cytokine levels on postoperative day 1, 3 and 5 and the occurrence of PPOI was analyzed.
Results:
Eight patients developed PPOI, which was diagnosed on postoperative day 10-15. PCT levels on postoperative day 1 and 3 were not significantly different between the 8 patients who developed PPOI and the 92 patients without PPOI. In contrast, PCT levels on day 5 were significantly higher in patients who developed PPOI than in patients without PPOI. The levels of CRP and TNF-α were irregular from day 1 to 5, and were not significantly different.
Conclusions:
Increased PCT levels in abdominal exudate may predict PPOI in the early period following colorectal surgery.
