[The Effect of Fennel Tea Drinking on Postoperative Gut Recovery after Gynecological Malignancies Operation]

To reveal if whether fennel fruit (Fructus Foeniculi) tea drinking enhances the recovery of intestinal function after gynecologic malignancies operation.

A total of 159 patients undergoing laparotomy for gynecological cancers were randomized into a tea group (n=78) and a control group (n=81). The patients in tea group drank a cup of fennel fruit tea while patients in control group drank the equal quantity of water twice per day from the first morning after operation until the first flatus. Every cup of tea consists of 5 gram of dried fennel fruit and 130 mL boiled water. The patents only drank the filtrate. Groups were compared in terms of time to first flatus and defecation, postoperative hospital stay, length of parenteral nutrition, ileus symptoms and other postoperative complications.

Postoperative hospital [(5.6 +/- 1.2) d vs. (6.7 +/- 2.0) d, P<0.001], the mean time to flatus [(53.1 +/- 11.3) h vs. (64.2 +/- 13.6) h, P<0.001)], and the mean time to defecation [(4.3 +/- 1.0) d vs. (5.4 +/- 1.2) d, P < 0.001)] were significantly lower in tea group compared with those in control group. Ileus symptoms were observed more in patients in the control group compared to patients in tea group [relative risk = 2.6; 95% confidence interval, 1.5-4.5; P=0.001].

Fennel tea drinking after laparotomy for gynecological malignancis, an economical care, is safe, well to lerated and associated with rapider recovery of bowel motility, shorter hospital stay and fewer complications.
