    ABSTRACT: Closure of the fistula tract with an anal fistula plug has been reported to provide success rates as high as 80%. The purpose of this study was to evaluate our results with this new method. From June 2006 to September 2007, an anal fistula plug was used for the treatment of high transsphincteric fistulas. Success was defined as no residual leakage or abscess formation and closure of the external opening. Fifteen patients (seven women), median age 46 years (range 32-58 years), were included in the study. Three had Crohn's disease, three had an anovulvar fistula and seven had undergone previous surgical-repair attempts. Three patients expelled the prosthesis on postoperative day 2, 5 and 7, respectively, and a second plug placement was followed by expulsion again. One patient developed an abscess that was noted on postoperative day 4. The fistula tract healed in 6/15 patients (40%) after 3 months and in 8/15 (53.3%) after 7 months. The success rate in Crohn's disease was 33%. No significant difference was found between patients with or without previous surgical repair. In our experience, this simple technique provided success rates of 40% at 3 months and 53% at 7 months.

    ABSTRACT: Background / Purpose: Using Dindo’s classification of surgical complications, the aims of this study were to evaluate morbidity, mortality and identify risks factors among the patients who underwent ileorectal anastomosis (IRA) for various colonic diseases.Between June 1994 and May 2008, all patients who underwent a total colectomy (TC) with formation of an IRA in our institution were reviewed. Collecting data from medical records, we listed all medical, surgical complications, including anastomotic leakage and mortality. Dindo’s classification was used to grade postoperative complications.Patient’s characteristics, aetiologies and surgical procedures are detailed in Table 1 on the Poster. Postoperative complications are detailed in Table 2 using Dindo’s classification, and Table 3 shows their occurrence according to underlying pathology. Main conclusion: IRA should be considered as a safe procedure with only 7% of anastomotic leakage. Age and non-elective surgery are independent risk factors for medical complications whereas age is the only risk factor for surgical complications.

    ABSTRACT: Before undergoing sacral nerve stimulation (SNS) for faecal incontinence (FI), patients are investigated with morphologic, dynamic and electrophysiologic tests. The purpose of our study was to evaluate their value in the selection of patients who may benefit most from neuromodulation. If temporary stimulation resulted in a good objective response, a permanent neuromodulator was implanted. Patients were reviewed at 3 months and then at 6 monthly intervals. Asked by telephone, patient's satisfaction was described as good, satisfactory or poor. Forty-five consecutive patients (41 females, median age 59 years) with FI (Wexner 16.1 +/- 2.9) underwent SNS. Temporary stimulation was successful in 32 (71)% patients. At a median follow-up of 33 months, the neuromodulator remained in place in 25 (55%) patients, two do whom switched it off, leaving 23 (51%) with a functioning neuromodulator. There was no statistically significant difference between the characteristics (including manometry, ultrasound and electrophysiology) of patients undergoing implantation (n = 32) or not (n = 13) and those with or without a functioning stimulator (n = 23: n = 13). In the 23 patients with a functioning stimulator the result was good in 12, satisfactory in five and poor in six. There was no statistically significant difference in the patient characteristics between those with a good result (n = 12) and the remainder (n = 32). The findings suggest that investigation for FI does not facilitate patient selection for SNS and cannot be used to predict outcome.
