OBJECTIVE: Some conditions, previously managed by general surgeons, may be treated more successfully by colorectal specialists. This argument is well established for rectal cancer but does it also apply to benign conditions? This study compares the treatment strategies and outcomes for fistulae-in-ano by general and colorectal surgeons in a district general hospital.
METHOD: Patients who had surgery for fistula-in-ano from January 1992-October 2003 were identified from theatre records. Case notes were reviewed for data on type of fistula, aetiology, surgery performed and recurrence. All patients were sent a questionnaire requesting details of recurrence and incontinence. The severity of incontinence was assessed using the Faecal Incontinence Quality of Life Scale (FIQOLS) and the Faecal Incontinence Severity Index (FISI).
RESULTS: Eighty four patients (male = 53) were identified. Colorectal surgeons performed surgery in 34 and general surgeons in 50 patients. These groups were comparable with terms of age, gender, aetiology (colorectal: IBD = 5, cryptoglandular = 21: general IBD = 14, cryptoglandular = 24; P = 0.28; Chi-squared test), and type of fistulae (colorectal: inter-sphincteric = 20, trans-sphincteric = 13: general inter-sphincteric = 30, trans-sphincteric = 18: P = 1.0; Fisher's exact test). Colorectal surgeons carried out fewer fistulotomies (47.1%vs 84.0%; P < 0.001; Fisher's exact test), more staged fistulotomies with Setons (44.1%vs 10.0%: P < 0.001; Fisher's exact test), and had fewer recurrences (9.7%vs 30.0%: P < 0.05; Fisher's exact test) when compared with general surgeons. Five patients with recurrence from the general surgery group were subsequently referred to the colorectal surgeons; four patients had further surgery (fistulotomy = 2; staged fistulotomy = 2) with no recurrence to date; one patient required proctectomy. Forty seven (64.4%) patients answered the questionnaire. There was no difference between patients operated on by colorectal or general surgeons with regards the frequency (43.5%vs 62.5%: P = 0.25; Fisher's exact test) or severity [FISI 26 (21-38); median (inter-quartile range) vs 26 (17-38); median (inter-quartile range: P = 0.85; Mann-Whitney test) of faecal incontinence. There was no difference between the groups with regards any of the four scales that comprised the FIQOLS.
CONCLUSIONS: The number of included patients is far too low to draw any conclusions but there were some interesting trends. For similar patient samples, colorectal surgeons seem to adopt a more conservative approach and have fewer recurrences than general surgeons. These differences are not reflected in the frequency or severity of postoperative incontinence.
