Abstract
AIM: To assess the efficacy of biofeedback therapy in the patients received intersphincteric resection for very low rectal cancer.
METHODS: From 1999 to 2006, a total of 16 patients underwent intersphincteric resection, and all of them received biofeedback treatments. Therapeutic responses were evaluated with Vaizey, Wexner scoring systems and vectorial manometry.
RESULTS: After biofeedback treatments, the Vaizey and Wexner scores were markedly decreased as compared with those before treatments (6.4 vs 8.6, P < 0.001; 5.4 vs 7.2, P < 0.001); the maximal contraction pressure (mmHg) and contraction vector volume [cm×(mmHg)2] were significantly increased (205.6 ± 44.5 vs 143.6 ± 46.5, P < 0.001; 50 664.6 ± 8040.1 vs 13 337.0 ± 7491.1, P < 0.001); the asymmetric index as the resting or contracting of sphincter was dramatically down-regulated (46.8 ± 7.5 vs 58.3 ± 7.4, P < 0.001; 29.9 ± 6.7 vs 38.3 ± 7.2, P < 0.001); at last, the positive rate of rectoanal reflex was also increased from 6.3% to 31.3%.
CONCLUSION: The maximal pressure and vector volume are deficient in patients after intersphincteric resection, while biofeedback therapy can partly improve the anal sphincter function ......
