Donor stool is obtained from OpenBiome, a third-party stool bank that screens donors for medication use, allergies, and health-related conditions and prepares stool per a standard protocol including suspension in normal saline. 250ml of donor stool is used for colonoscopic FMT in patients with over one meter squared of body surface area. For small children this quantity may be reduced proportionately. The entire 250ml's are placed into the ileum, cecum and/or ascending colon, or at the extent reached by the colonoscope, via the operative channel of the colonoscope. Patients are asked to maintain a right lateral recumbent position as much as possible for the hour after infusion, to encourage permanence of the material in the proximal colon. Of note, the FMT colonoscopy does not include meticulous mucosal examination if not otherwise indicated, and as such is not a substitute for routine colorectal cancer screening. Patients are monitored by post-anesthesia care unit (PACU) personnel until ready for discharge, per standard unit protocol.
