Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The effects of coffee have been shown to act as a colonic stimulant. Caffeinated coffee stimulates colonic activity, most notably in the transverse/descending colon, in magnitude similar to a meal, 60% stronger than water, and 23% stronger than decaffeinated coffee. \[1\] Moreover, the consumption of both water and caffeine causes a decrease in the rectal sensory threshold for the desire to defecate, while anal sphincter pressure after caffeine intake is significantly higher than after water intake. This may result in an earlier desire to defecate. \[2\] Coffee has also been shown to have an effect on defecation by increasing rectal tone by 45% (measured with a barostat) thirty minutes after consumption. \[3\]

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study Objectives

Primary objective: To determine if the use of coffee in the postoperative period will reduce time to recovery of GI function by at least one day in patients undergoing elective colorectal operations. (This will be assessed by twice daily interview of patients as to whether they have passed flatus or had a bowel movement)

Secondary objective: To determine if the use of coffee in the postoperative period will reduce hospital length of stay by at least one day, and to also evaluate the tolerance of solid food, which will help determine postoperative ileus and rates of vomiting/nasogastric tube (re)insertion, and other perioperative morbidities such as anastomotic leak, wound infection, and intra-abdominal abscesses in patients undergoing elective colorectal operations.

Study Design

This study involves the evaluation of patients who consume coffee compared with patients who consume warm water during the postoperative period after elective colorectal surgery with primary anastomosis.

This study will be a single-center, randomized trial. Patients who undergo elective colorectal surgery at Cedars-Sinai Medical Center and agree to participate in the study will be randomized 1:1:1 to those who drink regular coffee, decaffeinated coffee, and no coffee. Randomization will occur via an online program (www.randomizer.org), which assigns participants to experimental conditions. The subjects assigned to drink regular coffee, decaffeinated coffee, or warm water will be given a 4oz cup three times daily and will be instructed to consume all of its liquid contents.

Postoperative care will otherwise be the same for all subjects, as dictated by the clinical judgment of the surgical team.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Regular coffee

Will receive a 4oz cup coffee, three times daily (at 8:00, 12:00, and 16:00 hours)and instructed to consume the entirety of its liquid contents. This liquid consumption will begin on the morning of POD #1 at 8:00 hours. Duration of experimental treatment will last until first flatus or bowel movement or 7 days, whichever comes first.

Group Type EXPERIMENTAL

Regular Coffee

Intervention Type OTHER

Regular coffee will be given a 4oz cup three times daily and will be instructed to consume all of its liquid contents.

Decaffeinated coffee

Will receive a 4oz cup of decaffeinated coffee (at 8:00, 12:00, and 16:00 hours) and instructed to consume the entirety of its liquid contents. This liquid consumption will begin on the morning of POD #1 at 8:00 hours. Duration of experimental treatment will last until first flatus or bowel movement or 7 days, whichever comes first.

Group Type EXPERIMENTAL

Decaffeinated coffee

Intervention Type OTHER
