OBJECTIVE: The objective of this selective EBM review is to determine whether or not “Is postoperative consumption of coffee effective in reducing postoperative ileus?”

STUDY DESIGN: Review of three randomized controlled trials written in the English language and were published in 2017, 2015, and 2012.

DATA SOURCES: Three randomized control trials were found via PubMed.

OUTCOMES MEASURED: Time in days from the end of surgery until the first passage of stool recorded by patient, or time measured in hours reported by nursing staff.

RESULTS: Dulkskas, et al. (2015) found that the time until the first bowel movement (measured in days) was significantly (p < 0.05) shorter in the coffee group (3.75 ± 1.53) and water groups (4.14 ± 1.14). Muller et al (2012) found that the time to the first postoperative bowel movement was significantly shorter in the coffee arm than in the water arm (p = 0.006). Finally, Gungorduk, et al. (2017) stated the mean time to defecation in patients who consumed coffee postoperatively vs the control group was significantly reduced (43.1±9.4 vs 58.5±17.0 hours; P<.001).

CONCLUSION: Postoperative consumption of coffee is a well-tolerated and cheap method of therapy to prevent and reduce the likelihood of prolonged postoperative ileus. All three studies demonstrate that coffee consumption after intraperitoneal surgery significantly (p<0.05) reduced time to first defecation after surgery compared to the control group that consumed only water postoperatively.
