Reduction in adhesive small-bowel obstruction by Seprafilm adhesion barrier after intestinal resection.

IntroductionAlthough Seprafilm® has been demonstrated to reduce adhesion formation, it is not known whether its usage would translate into a reduction in adhesive small-bowel obstruction.MethodsThis was a prospective, randomized, multicenter, multinational, single-blind, controlled study. This report focuses on those patients who underwent intestinal resection (n = 1,701). Before closure of the abdomen, patients were randomized to receive Seprafilm® or no treatment. Seprafilm® was applied to adhesiogenic tissues throughout the abdomen. The incidence and type of bowel obstruction was compared between the two groups. Time to first adhesive small-bowel obstruction was compared during the course of the study by using survival analysis methods. The mean follow-up time for the occurrence of adhesive small-bowel obstruction was 3.5 years.ResultsThere was no difference between the treatment and control group in overall rate of bowel obstruction. The incidence of adhesive small-bowel obstruction requiring reoperation was significantly lower for Seprafilm® patients compared with no-treatment patients: 1.8 vs. 3.4 percent (P < 0.05). This finding represents an absolute reduction in adhesive small-bowel obstruction requiring reoperation of 1.6 percent and a relative reduction of 47 percent. In addition, a stepwise multivariate analysis indicated that the use of Seprafilm® was the only predictive factor for reducing adhesive small-bowel obstruction requiring reoperation. In both groups, 50 percent of first adhesive small-bowel obstruction episodes occurred within 6 months after the initial surgery with nearly 30 percent occurring within the first 30 days. Additionally no first adhesive small-bowel obstruction events were reported in Years 4 and 5 of follow-up.ConclusionsThe overall bowel obstruction rate was unchanged; however, adhesive small-bowel obstruction requiring reoperation was significantly reduced by the use of Seprafilm®, which was the only factor that predicted this outcome.

Readmission rates and cost following colorectal surgery

BACKGROUND: Hospital readmission is emerging as a quality indicator by the state, federal, and private payors with the goal of denying payment for select readmissions. OBJECTIVE: We designed a study to measure the rate, cost, and risk factors for hospital readmission after colorectal surgery. STUDY DESIGN/SETTING: We reviewed commercial health insurance records of 10,882 patients who underwent colorectal surgery over a 7-year period (2002–2008). PATIENTS: All patients undergoing colon and/or rectal resection ages 18 to 64 were included. MAIN OUTCOME MEASURE: The 30-day and 90-day readmission rates, the number of readmissions per patient, the median cost, length of stay, and risk factors for readmission were analyzed. RESULTS: Thirty-day readmission occurred in 11.4% (1239/10,882) of patients. Readmission between 31 and 90 days occurred in an additional 11.9% (1027/10,882) of patients for a total 90-day readmission rate of 23.3%. Two or more readmissions occurred in 1.4% (155) and 5.2% (570) of patients in the first 30 and 90 days. Mean readmission length of stay was 8 days, and the median cost per stay was

Initial hospitalization risk factors for readmission were the diagnosis of a surgical site infection (OR 1.2), creation of a stoma (OR 1.2), discharge to nursing home (OR 1.2), index admission length of stay >7 days (OR 1.2), proctectomy (OR 1.1), and severity of illness score (severity of illness 3 = OR 1.1; severity of illness 4 = OR 1.3). CONCLUSIONS: Readmission after colorectal surgery occurs frequently and is associated with a cost of approximately

Epigenetic Regulation of WNT Signaling Pathway Genes in Inflammatory Bowel Disease (IBD) Associated Neoplasia

Background: Crohns disease (CD) and ulcerative colitis (UC) result from pathophysiologically distinct dysregulated immune responses, as evidenced by the preponderance of differing immune cell mediators and circulating cytokine expression profiles. MicroRNAs (miRNAs) are small, noncoding RNAs that act as negative regulators of gene expression and have an increasingly recognized role in immune regulation. We hypothesized that differences in circulating immune cells in CD and UC patients are reflected by altered miRNA expression and that miRNA expression patterns can distinguish CD and UC from normal healthy individuals. Methods: Peripheral blood was obtained from patients with active CD, inactive CD, active UC, inactive UC, and normal healthy adults. Total RNA was isolated and miRNA expression assessed using miRNA microarray and validated by mature miRNA quantitative reverse‐transcription polymerase chain reaction. Results: Five miRNAs were significantly increased and two miRNAs (149* and miRplus‐F1065) were significantly decreased in the blood of active CD patients as compared to healthy controls. Twelve miRNAs were significantly increased and miRNA‐505* was significantly decreased in the blood of active UC patients as compared to healthy controls. Ten miRNAs were significantly increased and one miRNA was significantly decreased in the blood of active UC patients as compared to active CD patients. Conclusions: Peripheral blood miRNAs can be used to distinguish active CD and UC from healthy controls. The data support the evidence that CD and UC are associated with different circulating immune cells types and that the differential expression of peripheral blood miRNAs may form the basis of future diagnostic tests for inflammatory bowel disease.

Postoperative Venous Thromboembolism Rates Vary Significantly After Different Types of Major Abdominal Operations

BACKGROUND Surgical site infections (SSI) are a common and costly problem, prolonging hospitalization and increasing readmission. Adherence to well-known infection control process measures has not been associated with substantial reductions in SSI. To date, the global burden of preventable SSI continues to result in patient harm and increased health care costs on a broad scale. STUDY DESIGN We designed a study to evaluate the association between implementation of a surgery-based comprehensive unit-based safety program (CUSP) and postoperative SSI rates. One year of pre- and post-CUSP intervention SSI rates were collected using the high-risk pilot module of the American College of Surgeons National Surgical Quality Improvement Program (July 2009 to July 2011). The CUSP group met monthly and consisted of a multidisciplinary team of front-line providers (eg, surgeons, nurses, operating room technicians, and anesthesiologists) who were directly involved in the care of colorectal surgery patients. Surgical Care Improvement Project process measure compliance was monitored using standard methods from the Centers for Medicare and Medicaid Services. RESULTS In the 12 months before implementation of the CUSP and interventions, the mean SSI rate was 27.3% (76 of 278 patients). After commencement of interventions, the rate was 18.2% (59 of 324 patients) for the subsequent 12 months--a 33.3% decrease (95% CI, 9-58%; p < 0.05). The interventions included standardization of skin preparation; administration of preoperative chlorhexidine showers; selective elimination of mechanical bowel preparation; warming of patients in the preanesthesia area; adoption of enhanced sterile techniques for skin and fascial closure; addressing previously unrecognized lapses in antibiotic prophylaxis. There was no difference in surgical process measure compliance as measured by the Surgical Care Improvement Project during the same time period. CONCLUSIONS Formation of small groups of front-line providers to address patient harm using local wisdom and existing evidence can improve patient safety. We demonstrate a surgery-based CUSP intervention that might have markedly decreased SSI in a high-risk population.

Patterns of Recurrence Following Liver Resection for Colorectal Metastases: Effect of Primary Rectal Tumor Site

OBJECTIVES To measure the effect of obesity on surgical site infection (SSI) rates and to define the cost of SSIs in patients undergoing colorectal surgery. DESIGN, SETTING, AND PATIENTS This is a retrospective cohort study of 7020 colectomy patients using administrative claims data from 8 Blue Cross and Blue Shield insurance plans. Patients who had a total or segmental colectomy for colon cancer, diverticulitis, or inflammatory bowel disease between January 1, 2002, and December 31, 2008, were included. MAIN OUTCOME MEASURES We compared 30-day SSI rates among obese and nonobese patients and calculated total costs from all health care claims for 90 days following surgery. Multivariate logistic regression was performed to identify risk factors for SSIs. RESULTS Obese patients had an increased rate of SSI compared with nonobese patients (14.5% vs 9.5%, respectively; P < .001). Independent risk factors for these infections were obesity (odds ratio = 1.59; 95% confidence interval, 1.32-1.91) and open operation as compared with a laparoscopic procedure (odds ratio = 1.57; 95% confidence interval, 1.25-1.97). The mean total cost was

Total length of stay was longer in patients with infection than in those without infection (mean, 9.5 vs 8.1 days, respectively; P < .001), as was the probability of hospital readmission (27.8% vs 6.8%, respectively; P < .001). CONCLUSIONS Obesity increases the risk of an SSI after colectomy by 60%, and the presence of infection increases the colectomy cost by a mean of
