Abstract
The aim of this study is to assess the safety and efficacy of Permacol® implant for the treatment of idiopathic faecal incontinence using a novel injection technique. Patients with idiopathic passive faecal incontinence were selected for trans-submucosal injection of Permacol® after assessment by anorectal physiology and endoanal ultrasonography. Clinical assessment and St. Mark’s Incontinence Score were used to evaluate efficacy before and at two time points (1 and 2 years) after treatment. Rockwood Score were also used to determine quality of life before and after treatment. The Friedman and Chi-square tests were used to compare continuous and categorical data, respectively. A p value of <0.05 was deemed significant. Thirty-eight patients (24 female), median age 66 years, were recruited. At maximum clinical follow-up (median of 9 months), response to Permacol® injections was categorised as excellent, good, fair and poor in 12, 5, 4 and 17 patients, respectively. St. Mark’s Score improved in 72 and 63 % of patients at 1 and 2 years, respectively. However, a smaller proportion of patients (39 and 27 %, respectively) achieved a 50 %, or more, improvement in Mark’s Score. All four domains of Rockwood Quality of Life Score improved on first and second year follow-up, however, only two domains, coping and embarrassment, were statistically significant. Permacol® injection improved symptoms by >50 % in 39 and 27 % of patients on short and medium-term follow-ups, respectively. The trans-submucosal technique for injection of Permacol® in this study was safe with no significant adverse outcomes.
