Role of fecal microbiota transplant in management of hepatic encephalopathy: Current trends and future directions

Table 4 Comparison of different fecal microbiota transplant preparation methods

FMT preparation method	Efficacy range (%)	Preservation of microbial diversity	Advantages	Disadvantages
Fresh[40]	85-100	High	Contains diverse microbial population	Requires immediate availability of the patient
Frozen[40]	83-95	Moderate	Allows for long term storage	Loss of some microbial diversity during freezing; Comprise on efficacy if not stored properly and use of incorrect thawing techniques
Frozen lyophilized[40]	78-84	Moderate	Longer shelf life; Can be easily incorporated into a capsule	Loss of some microbial diversity during encapsulation
