BACKGROUND: The importance of the overlapping scar in an anterior sphincteroplasty is often emphasized. The aim of this study was to identify the tissue type used in overlapping sphincter repair based upon ultrasound images, and to correlate these results with the immediate clinical outcome. METHODS: Data were collected prospectively on all patients with faecal incontinence who underwent anterior overlapping sphincteroplasty between June 1998 and May 1999. Continence was assessed by a standardized incontinence score ranging from 0 to 20. Pre-operative ultrasound images were compared to intraoperative ultrasound findings for each patient. In each case the surgeon performed an overlap of what was grossly felt to represent scar after which a single blinded observer performed intraoperative ultrasound. The degree of overlap was measured and classified as hyperechoic over hyperechoic (muscle over muscle; Type 1), hyperechoic over or under hypoechoic (muscle over or under scar; Type 2), hypoechoic over hypoechoic (scar over scar; Type 3). The patient follow-up included incontinence score that was obtained by telephone interview; suboptimal outcome was considered as an incontinence score >/= 6. Statistical analysis was performed using the Mann-Whitney test and Wilcoxon matched-pairs test. RESULTS: Fourteen female patients with a mean age of 51.6 (range 28-79) years were evaluated. The mean pre-operative incontinence score was 17.1 (range 7-20) and 13 of the 14 (93%) patients had an incontinence score >/= 15. All pre-operative ultrasound images were hypoechoic which correlated with the surgeon's intraoperative findings of scar. The operative appearance included two Type 1, four Type 2, and eight Type 3 images. Larger pre-operative ultrasound image defects were statistically significantly related to intraoperative Type 3 ultrasound images. At a mean follow up of 7.5 (range 2-16) months the mean postoperative incontinence score was 4.5 (range 0-12). In patients with Type 1 and Type 2 images, the mean postoperative score was 8.6 (range 4-12) whereas in patients with Type 3 it was 1.3 (range 0-5) (P < 0.003); 7 of the 8 patients in Type 3 (87.5%) had an incontinence score

The present review deals with the elective and emergency management of colonic Crohn's disease (CD). Failed medical therapy is among the most common indications for the operative treatment. In case of fistula the operation is usually a resection of the diseased segment of colon with wedge or segmental excision and closure of the secondarily involved organ. The incidence of Crohn's colonic stricture ranges from 5% to 17%. The main indication for performing a total colectomy and ileoproctostomy in patients with extensive Crohn's colitis is to avoid a permanent ileostomy and preserve rectal function. The authors performed 60 laparoscopic procedures: 35 ileocolic resections, 10 total colectomies, 10 loop ileosigmoidectomies, and 1 proctectomy. In conclusion, the choice of operation depends on many factors, such as the site and extent of disease. In some select instances a segmental resection of CD may afford better function than an ileoproctostomy.
