Does adjuvant antibiotic treatment after drainage of anorectal abscess prevent development of anal fistulas? A randomized, placebo-controlled, double-blind, multicenter study.

BACKGROUND: The risk of fistula formation is a major concern after incision and drainage of an anorectal abscess. OBJECTIVE: Our objective was to the test the effects of antibiotic treatment on fistula formation after incision and drainage of anorectal abscesses. DESIGN: Randomized, placebo-controlled, double-blind study. SETTING: Multicenter trial at 3 teaching hospitals in Turkey. PATIENTS: Patients who underwent abscess drainage between September 2005 and January 2008 were evaluated for eligibility. Exclusion criteria included penicillin allergy, antimicrobial agent usage before enrolment, other infection, previous anorectal surgery, inflammatory bowel disease, suspicion of Fournier gangrene, secondary and recurrent anorectal abscesses, anal fistula at time of the surgery, immune compromised states, and pregnancy. INTERVENTION: Patients were randomly assigned to receive placebo or amoxicillin-clavulanic acid combination treatment for 10 days after abscess drainage. MAIN OUTCOME MEASURES: The primary end point was rate of anorectal fistula formation at 1-year follow-up. RESULTS: : Of 334 patients assessed for eligibility, 183 entered the study (placebo, 92; antibiotics, 91). Data were available for per-protocol analysis from 151 patients (placebo, 76; antibiotics, 75) with a mean age of 37.6 years; 118 patients (78.1%) were men. Overall, 45 patients (29.8%) developed anal fistulas during 1-year follow-up. Fistula formation occurred in 17 patients (22.4%) in the placebo group and in 28 patients (37.3%) in the antibiotic group (P = .044). Risk of fistula formation was increased in patients with ischiorectal abscess (odds ratio, 7.82) or intersphincteric abscess (odds ratio, 3.35) compared with perianal abscess. CONCLUSION: Antibiotic treatment following the drainage of an anorectal abscess has no protective effect regarding risk of fistula formation.

Professional holistic care of the person with a stoma: online learning.

Stoma care nurse specialists are valued for their diverse expertise, but it is essential that all practitioners who regularly care for people with stomas have the opportunity to develop professionally and influence this important area of practice. The vision of a clinical and educational team from Suffolk and south Norfolk led to the development of innovative web-based learning material. The aim is to inspire nurses to engage actively with people who have a stoma. 'Professional care of the person with a stoma' is about caring for the whole person, physically and emotionally, from the period before surgery, to their continuing care in the community. An overview of four aspects of stoma care is presented here as a way of sharing with a wider audience the expert practice harnessed during the development of this web-based module.

[Mechanical preparation in elective colorectal surgery, a usual practice or a necessity?]. / Preparación mecánica en cirugía electiva colo-rectal. Costumbre o necesidad?

UNLABELLED: Pre-operative preparation of the colon is carried out with oral and/or intravenous administration of antibiotics and through the mechanical preparation of the colon using various substances to decrease the intraluminal bacterial concentration and remove the larger quantity of fecal material as possible, thus decreasing the risk of anastomosis dehiscence due to an increase in the intraluminal pressure. The role of antibiotics has been completely established while that of mechanical preparation is still questioned. The objective of this study is to assess the actual impact of mechanical preparation on colorectal surgery. MATERIALS AND METHODS: Forty seven patients who underwent elective colorectal surgery were prospectively evaluated, out of which only 24 had mechanical preparation. We compared variables such as age, sex, preoperative hemoglobin, albumin and leukocyte values, surgery characteristics and type of anastomosis, as well as complications in both groups. RESULTS: We found a higher incidence of fistulas, dehiscences and general complications in the group undergoing mechanical preparation of the colon. CONCLUSION: The results show that mechanical preparation of the colon does not provide any benefit and may result in a higher incidence of complications in colorectal surgery.
