Objective. To investigate the effects and safety of the aqueous extract of the dried, immature fruit of Poncirus trifoliata (L.) Raf., known as Poncirus fructus (PF), in spinal cord injury (SCI) patients with neurogenic bowel. Methods. Thirty-one SCI patients with neurogenic bowel were recruited. Patients were evaluated based on clinical information, constipation score, Bristol Stool Form Scale, stool retention score using plain abdominal radiograph, and colon transit time. PF was administered in dosages of 800 mg each prior to breakfast and lunch for 14 days. Results. The morphological feature of the stool before and after administration indicated a statistically significant difference from 3.52 ± 1.33 to 4.32 ± 1.44 points (p<0.05). Stool retention score before and after administration of PF was represented with low significance (7.25 ± 1.60 to 6.46 ± 1.53 points) in the whole colon (p<0.05), and the colon transit time was significantly shortened (57.41 ± 20.7 to 41.2 ± 25.5 hours) in terms of the whole transit time (p<0.05). Side effects were observed in 7 people (28.0%) consisting of 2 people with soft stools and 5 people with diarrhea. Conclusion. For SCI patients, PF administration significantly improved defecation patterns, defecation retention, and colon transit time. PF could be an effective aid to improve colonic motility and constipation. [ABSTRACT FROM AUTHOR]

Study design:A 6-month follow-up study.Objectives:To investigate the outcome of transanal irrigation (TAI) in patients with spinal cord injury (SCI) and to identify factors significantly related to clinical success.Setting:Survey for community-dwelling patients with SCI in South Korea.Methods:Between December 2010 and March 2012, TAI was initiated with 52 patients (41 men; age: 44.5±11.0 years) with neurogenic bowel dysfunction (NBD). At 1, 3 and 6 months after initiation, a telephone interview was conducted. Data were collected on patient-specific bowel management and TAI performance as a new procedure.Results:Only 18 patients (34%) used TAI for at least 6 months, which was a lower compliance rate than similar studies in some European countries. Relative to the compliant group, the noncompliant group contained a higher proportion of tetraplegia than paraplegia (P=0.031), and a higher proportion dependent on physical help (P=0.034). In all, 33 of the 52 patients (63.5%) complained of practical problems with the TAI procedure such as expulsion of the rectal catheter. Fifteen patients (28.8%) presented with adverse effects. The incidence of practical problems or adverse effects did not alter the frequency of patient-reported successful outcome.Conclusion:Korean participants showed a relatively lower compliance rate with TAI. We conclude that TAI, combined with adequate patient instruction and physical assistance, has potential as a management tool for NBD in Korea. [ABSTRACT FROM AUTHOR]
