Bilateral gracilis neosphincter construction for treatment of faecal incontinence.

Neosphincter formation with gracilis muscle is used for faecal incontinence refractory to conservative measures and after failed sphincter repair. In this study both gracilis muscles were used to create a neosphincter to determine whether this provides superior physiological and clinical results. Ten patients of median age 39 (range 18-73) years were treated. The mean resting and squeeze pressures before operation were 16 (range 0-40) and 44 (range 0-68) cmH2O respectively. The operation was covered by a defunctioning loop left iliac fossa colostomy. Nine of the ten patients have had the stoma closed and are fully continent after a mean follow-up of 24 (range 6-40) months. One patient who had an ileoanal pouch and bilateral graciloplasty has urgency of defaecation. None of the patients has to wear a pad or is taking constipating agents. All nine patients have satisfactory evacuation on isotope defaecography and are continent to artificial stool. After operation the mean resting and squeeze pressures were 78 (range 70-112) and 121 (range 90-188) cmH2O respectively. Bilateral graciloplasty provides satisfactory results for grade 4 faecal incontinence refractory to other operative and non-operative measures, and may be an alternative to stimulated dynamic graciloplasty.
