IMPORTANCE Surgical site infection following stoma reversal (SR) poses a substantial burden to the patient and health care system. Its overall incidence is likely underreported and poorly characterized. Improving our understanding of surgical site infection following stoma reversal may help us identify methods to decrease this complication. OBJECTIVE To evaluate the incidence of surgical site infection (SSI) and identify predictors of SSI following SR. DESIGN A review of computerized hospital records on SR performed from January 1, 2005, until February 27, 2011. SETTING An integrated medical system at the Michael E. DeBakey Veterans Affairs Medical Center. PARTICIPANTS AND INTERVENTION All adults undergoing SR during the study period. MAIN OUTCOME MEASURES Rates of SSI and characteristics of patients with and without SSI were compared. A logistic regression model was developed to identify predictors of SSI. RESULTS One hundred twenty-eight patients underwent SR; 46 patients (36.0%) had an SSI. In comparison with no SSI, the infection was associated with seromas (17.4% vs 2.4%, P = .004), fascial dehiscence (15.2% vs 2.4%, P = .01), intensive care unit admission (34.8% vs 17.1%, P = .03), increased hospital length of stay (20 vs 9 days, P = .02), readmission (32.6% vs 13.4%, P = .01), delayed wound healing (91 vs 66 days, P = .02), and reoperation (32.6% vs 13.4%, P = .01). On multivariate analysis, history of fascial dehiscence (odds ratio, 16.9; 95% CI, 1.94-387), colostomy (5.07; 2.12-13.0), thicker subcutaneous fat (2.02; 1.33-3.21), and black race (0.35; 0.13-0.86) were associated with incisional SSI. There was no significant difference in patient satisfaction or functional status in late follow-up (1-73 months). CONCLUSIONS AND RELEVANCE Surgical site infection is common following SR and is associated with significant morbidity. Four factors are strongly associated with increased risk of SSI in SR: history of fascial dehiscence, thicker subcutaneous fat, colostomy, and white race. Patients with none of these risk factors had a 0% SSI risk; patients with all 4 risk factors had a 100% risk of SSI.

ABSTRACT: Large databases provide a wealth of information for researchers, but identifying patient cohorts often relies on the use of current procedural terminology (CPT) codes. In particular, studies of stoma surgery have been limited by the accuracy of CPT codes in identifying and differentiating ileostomy procedures from colostomy procedures. It is important to make this distinction because the prevalence of complications associated with stoma formation and reversal differ dramatically between types of stoma. Natural language processing (NLP) is a process that allows text-based searching. The Automated Retrieval Console is an NLP-based software that allows investigators to design and perform NLP-assisted document classification. In this study, we evaluated the role of CPT codes and NLP in differentiating ileostomy from colostomy procedures. Using CPT codes, we conducted a retrospective study that identified all patients undergoing a stoma-related procedure at a single institution between January 2005 and December 2011. All operative reports during this time were reviewed manually to abstract the following variables: formation or reversal and ileostomy or colostomy. Sensitivity and specificity for validation of the CPT codes against the mastery surgery schedule were calculated. Operative reports were evaluated by use of NLP to differentiate ileostomy- from colostomy-related procedures. Sensitivity and specificity for identifying patients with ileostomy or colostomy procedures were calculated for CPT codes and NLP for the entire cohort. CPT codes performed well in identifying stoma procedures (sensitivity 87.4%, specificity 97.5%). A total of 664 stoma procedures were identified by CPT codes between 2005 and 2011. The CPT codes were adequate in identifying stoma formation (sensitivity 97.7%, specificity 72.4%) and stoma reversal (sensitivity 74.1%, specificity 98.7%), but they were inadequate in identifying ileostomy (sensitivity 35.0%, specificity 88.1%) and colostomy (75.2% and 80.9%). NLP performed with greater sensitivity, specificity, and accuracy than CPT codes in identifying stoma procedures and stoma types. Major differences where NLP outperformed CPT included identifying ileostomy (specificity 95.8%, sensitivity 88.3%, and accuracy 91.5%) and colostomy (97.6%, 90.5%, and 92.8%, respectively). CPT codes can identify effectively patients who have had stoma procedures and are adequate in distinguishing between formation and reversal; however, CPT codes cannot differentiate ileostomy from colostomy. NLP can be used to differentiate between ileostomy- and colostomy-related procedures. The role of NLP in conjunction with electronic medical records in data retrieval warrants further investigation.Surgery 06/2013; 154(2). DOI:10.1016/j.surg.2013.05.022 · 3.38 Impact Factor

ABSTRACT: Patient-related outcome measures (PROM) such as quality of life (QoL) after hernia repair are important to monitor, since QoL is an important indication of a hernia repair. Carolinas Comfort Scale (CCS) is a hernia-specific questionnaire regarding health-related QoL after a mesh hernia repair. The primary objective of this study was to monitor changes in health-related QoL over time after different mesh hernia repair procedures using the CCS. We performed a prospective study with an exploratory, intraobserver design enrolling consecutive patients who were to undergo elective mesh hernia repair. Four different hernia repair techniques were included and analyzed specifically for each surgical group. Patients scored themselves using CCS preoperatively and at several fixed times postoperatively. Since no gold standard exists for either hernia-specific QoL questionnaires or change of scores on PROMs as a function of time after hernia repair, we compared the CCS scores with the visual analog scale (VAS) scores reflecting the subdomains of the CCS. A total of 166 patients completed the study. CCS scores for QoL, pain, sensation of mesh, and activity limitations changed significantly with time during the 90-day study period. Furthermore, CCS and VAS showed significant agreement and correlation (ρ = 0.52-0.82, P < 0.001). The present study is the first to demonstrate significant changes over time in health-related QoL using the CCS after four different types of hernia repair with mesh.World Journal of Surgery 12/2013; 38(7).

ABSTRACT: The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.Cirugía Española 02/2014; 92(6).
