Abstract
ObjectiveTo evaluate the efficacy of periodic fecal microbiota transplantation (FMT) for refractory constipation.
MethodsClinical data of 49 patients with refractory constipation undergoing FMT through standard transplantation path of nasojejunal tube between April 2015 and April 2016 in Intestinal Microenvironment Treatment Centre of Nanjing General Hospital were analyzed retrospectively. Of 49 patients, 25 received single FMT for only 6 days (single group) , and 24 received periodic FMT with another 6 days FMT 1 month after the first 6 days FMT (periodic group) . The follow up was at 12 weeks after treatment. Autonomous defecation frequency, Wexner constipation score, gastrointestinal quality of life index and related adverse reaction were evaluated and compared at 4-, 8- and 12-week after treatment. Statistical analysis was performed on the difference after treatment at each time point, and the greater difference indicated the better improvement.
ResultsThere were no statistically significant differences in general characteristics between the two groups (allP < 0.05) . Before treatment, Wexner constipation score was 17.32 ± 2.66 and 16.25 ± 2.47, gastrointestinal quality of life index was 81.84 ± 8.73 and 83.25 ± 7.87, autonomous defecation frequency was (1.64 ± 0.57) time/week and (1.42 ± 0.65) time/week in single group and periodic group respectively, whose differences were not significant (all P > 0.05) . Compared with before FMT treatment, the autonomous defecation frequency, Wexner constipation score, gastrointestinal quality of life index were obviously improved at the 4-, 8-, 12-week (all P = 0.000) . At the 4-week after FMT treatment, the improvement degree of autonomous defecation frequency, Wexner constipation score, gastrointestinal quality of life index was compared between two groups, and no statistically significant differences were found (all P > 0.05) . While at 8-week and 12-week after FMT treatment, as compared to single group, periodic group had greater Wexner constipation score (at 8-week: 7.29 ± 2.05 vs. 5.96 ± 2.30, t=2.135, P = 0.038; at 12-week: 7.21 ± 1.98 vs. 5.80 ± 2.43, t = 2.218, P = 0.031) , greater gastrointestinal quality of life index (at 8-week: 25.71±8.91 vs. 20.20±8.53, t = 2.211, P = 0.032; at 12-week: 24.16 ± 8.99 vs.18.92 ± 8.28, t = 2.127, P = 0.039) and better autonomous defecation frequency [at 8-week: (2.42±0.93) time/week vs. (1.72±0.61) time/week, t = 3.110, P = 0.003; at 12-week: (1.37±0.88) time/week vs. (0.84 ± 0.62) time/week, t = 2.454, P = 0.018].
ConclusionPeriodic FMT has better efficacy than single FMT in the treatment of refractory constipation.
