Surgical site infection (SSI) is a potentially morbid and costly complication following major colorectal resection. In recent years, there has been growing attention placed on the accurate identification and monitoring of such surgical complications and their costs, measured in terms of increased morbidity to patients and increased financial costs to society. We hypothesize that incisional SSIs following elective colorectal resection are more frequent than is generally reported in the literature, that they can be predicated by measurable perioperative factors, and that they carry substantial morbidity and cost.
Over a 2-year period at a university hospital, data on all elective colorectal resections performed by a single surgeon were retrospectively collected. The outcome of interest was a diagnosis of incisional SSI as defined by the Center of Disease Control and Prevention. Variables associated with infection, as identified in the literature or by experts, were collected and analyzed for their association with incisional SSI development in this patient cohort. Multivariate analysis by stepwise logistic regression was then performed on those variables associated with incisional SSI by univariate analysis to determine their prognostic significance. The incidence of SSI in this study was compared with the rates of incisional SSI in this patient population reported in the literature, predicted by a nationally based system monitoring nosocomial infection, and described in a prospectively acquired intradepartmental surgical infection data base at our institution.
One hundred seventy-six patients undergoing elective colorectal resection were identified for evaluation. The mean patient age was 62 +/- 1.2 years, and 54% were men. Preoperative diagnoses included colorectal cancer (57%), inflammatory bowel disease (20%), diverticulitis (10%), and benign polyp disease (5%). SSIs were identified in 45 patients (26%). Twenty-two (49%) SSIs were detected in the outpatient setting following discharge. Of all preoperative and perioperative variables measured, increasing patient body mass index and intraoperative hypotension independently predicted incisional SSI. Although we could not measure statistically increased length of hospital stay associated with SSI, a representative population of patients with SSI accumulated a mean of $6200/patient of home health expenses related to wound care. Our rates of SSI were substantially higher than that reported generally in the literature, predicted by the National Nosocomial Infection System, or described by our own institutional surgical infection data base.
The incidence of incisional SSI in patients undergoing elective colorectal resection in our cohort was substantially higher than generally reported in the literature, the NNIS or predicted by an institutional surgical infection complication registry. Although some of these differences may be attributable to patient population differences, we believe these discrepancies highlight the potential limitations of systematic outcomes measurement tools which are independent of the primary clinical care team. Accurate surgical complication documentation by the primary clinical team is critical to identify the true frequency and etiology of surgical complications such as incisional SSI, to rationally approach their reduction and decrease their associated costs to patients and the health care system.

    ABSTRACT: Purpose. Surgical site infections (SSIs) remain a significant problem after laparotomies. The aim of this review was to assess the evidence on the efficacy of subcutaneous wound drainage in reducing SSI. Methods . MEDLINE database was searched. Studies were identified and screened according to criteria to determine their eligibility for meta-analysis. Meta-analysis was performed using the Mantel-Haenszel method and a fixed effects model. Results . Eleven studies were included with two thousand eight hundred and sixty-four patients. One thousand four hundred and fifty patients were in the control group and one thousand four hundred and fourteen patients were in the drain group. Wound drainage in all patients shows no statistically significant benefit in reducing SSI incidence. Use of drainage in high risk patients, contaminated wound types, and obese patients appears beneficial. Conclusion . Using subcutaneous wound drainage after laparotomy in all patients is unnecessary as it does not reduce SSI risk. Similarly, there seems to be no benefit in using it in clean and clean contaminated wounds. However, there may be benefit in using drains in patients who are at high risk, including patients who are obese and/or have contaminated wound types. A well designed trial is needed which examines these factors.

    ABSTRACT: The antibiotics used for prophylaxis in colorectal surgery must maintain appropriate plasma concentrations during the entire surgery to avoid surgical site infections caused by aerobes and anaerobes; cefuroxime plus metronidazole is one of the combinations used. The aim of this study was to evaluate the adequacy of cefuroxime plus metronidazole administration as prophylaxis in colorectal surgery. In total, 63 patients electively undergoing rectal or colon surgery were administered 1500mg of cefuroxime and 1500mg of metronidazole in 15-min and 1-h infusions, respectively, prior to surgery. Blood samples were withdrawn during and after surgery for determination of plasma concentrations by high-performance liquid chromatography. Population pharmacokinetic models were developed using NONMEM 7.2.0. Pharmacokinetic/pharmacodynamic (PK/PD) simulations were performed to explore the ability of different dosage regimens to achieve the pharmacodynamic targets. Pharmacokinetics for both antibiotics were best described by a two-compartment model. Elimination of cefuroxime was conditioned by creatinine clearance (CLCr). The half-life of cefuroxime was 1.5h for patients with normal renal function and 4.9h in patients with renal impairment. Elimination and distribution of metronidazole were affected by patient body weight (BW). PK/PD analysis revealed that a single-dose protocol of 1500mg of cefuroxime and metronidazole is adequate in short surgeries (≤2h). However, for longer surgeries, recommendations are suggested depending on the patient's CLCr and BW. Additional doses of cefuroxime are needed for patients with moderate renal impairment or those presenting normal renal function. For metronidazole, an additional dose is needed for patients with a BW of 90kg. Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy. All rights reserved.

    • "Obesity predisposes to a number of medical conditions. Current literature suggests obesity to be a risk factor for the development of umbilical hernias (UH) (Shenkman et al. 1993; Smith et al. 2004). Furthermore, obesity has been shown to influence not only surgical outcome but also the rate of recurrence in patients undergoing ventral hernia repair (Regnard et al. 1988; Sugerman et al. 1996; Sauerland et al. 2004).

    ABSTRACT: Obesity is a risk factor for the development of umbilical hernia. Open hernia closure could be challenging in obese patients leading to high rates of recurrence. The aim of this study was to investigate the effectiveness and safety of hernia patches in the management of obese patients with umbilical hernias. All the patients included in this study were managed in the department of surgery of a primary care hospital in Germany. The data of patients undergoing umbilical hernia repair within a two-year period was retrospectively reviewed. Patients managed with the PVP were included for analysis. 24 obese patients were analyzed. Small and medium size patches were used in 15 and 9 patients respectively. The median duration of surgery was 40 min and the median length of hospital stay was 4d. The mean length of follow-up was 12 ± 9 months (range: 6-30 months). The rate of recurrence was 4.1% and the rate of complication was 8.3%. Obese patients presenting with small and medium size umbilical hernias could be safely and effectively managed with prosthetic patches like the Proceed Ventral Patch. However, the limited overlap zone following hernia closure with such a patch can be an issue.
