Incisional Surgical Site Infection after Abdominal Fascial Closure with Triclosan-Coated Barbed Suture vs Triclosan-Coated Polydioxanone Loop Suture vs Polydioxanone Loop Suture in Emergent Abdominal Surgery: A Randomized Clinical Trial.

BACKGROUND: Triclosan-coated sutures have been shown to reduce surgical-site infection (SSI) in emergent operation for fecal peritonitis. Barbed sutures provoke a homogeneous distribution of tension throughout the suture, implying better blood supply to the wound edges and healing. The aim of this study was to evaluate the effect, on SSI and evisceration, of using triclosan-coated and barbed sutures for fascial closure in patients undergoing emergent surgery. STUDY DESIGN: A prospective, randomized clinical trial was performed. Patients were randomized into 3 groups: those undergoing aponeurotic closure with triclosan-coated barbed suture (Stratafix Symmetric [Johnson & Johnson]), patients undergoing closure with triclosan-coated polydioxanone loop suture (PDS plus [Johnson & Johnson]), and patients undergoing closure with polydioxanone loop suture (PDS [Johnson & Johnson]). Primary investigated outcomes were SSI and evisceration rates during a follow-up period of 30 days. The primary analysis plan was based on a per-protocol approach. RESULTS: Incisional SSI was 6.4% (3 of 47) in the Stratafix Symmetric group, 8.9% (4 of 45) in the PDS plus group, and 23.4% (11 of 47) in PDS group (p = 0.03). The evisceration rate was 0% in Stratafix Symmetric, 8.9% (4 of 45) in PDS plus, and 12.8% (6 of 47) in PDS (p = 0.05). Median hospital stay was 4 days (range 2 to 14 days) in Stratafix Symmetric, 5 days (range 2 to 21 days) in PDS plus, and 8 days (range 2 to 60 days) in PDS (p = 0.012). The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) was associated with a lower risk of incisional SSI (p = 0.009), and the use of barbed suture was associated with a lower risk of evisceration (p = 0.019). Comparing Stratafix Symmetric with PDS plus, there were no significant differences in SSIs, but the evisceration rate was significantly higher in the PDS plus group (p = 0.036). CONCLUSIONS: The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) in emergent surgery reduces the incidence of incisional SSIs. The use of barbed sutures reduces the incidence of evisceration.

Microbiologic Analysis of Complicated and Uncomplicated Acute Appendicitis.

BACKGROUND: Microbiologic studies suggest that complicated (CAA) and uncomplicated (UAA) acute appendicitis are different entities. Routine peritoneal fluid cultures continue to be controversially related to a low positive rate, found mainly in UAA; to isolation of typical micro-organisms with expected susceptibilities; and to a community-acquired intra-abdominal infection. The aim of this study was to describe microbiologic isolates in CAA and UAA and the usefulness of peritoneal fluid cultures to determine the susceptibilities to our antibiotic therapy guidelines. METHODS: This study was a retrospective review of a prospective database collected at University San Juan Hospital (Spain) between June 2014 and June 2017. Complicated acute appendicitis was defined as gangrenous or perforated, whereas UAA was defined as phegmonous or suppurative. Our antibiotic recommendations are amoxicillin-clavulanic acid and in patients with ß-lactam allergies, metronidazole plus aztreonam, and an aminoglycoside (gentamicin or tobramycin). Microbiologic cultures were performed in 264 patients, 157 with a CAA and 107 with a UAA. RESULTS: The positive culture rate was significantly higher in CAA (59%) than in UAA (24.3%). Gram-positive cocci (51.6% CAA; 23.1% UAA), including Streptococcus constellatus (29% CAA; 3.8% UAA), and anaerobes (67.7% CAA; 42.3% UAA) were significantly more common in CAA. The rates of antibiotic resistance were amoxicillin-clavulanic acid 14% (17.2% CAA; 3.8% UAA), gentamicin or tobramycin 8.4% (9.7% CAA; 3.8% UAA), ciprofloxacin 5.9% (6.5% CAA; 3.8% UAA), and ertapenem 10.9% (14% CAA; 0 UAA). CONCLUSIONS: The culture-positive rate was higher in CAA, with different isolates and susceptibilities than in UAA, identifying a higher frequency of gram-positive cocci (including S. constellatus) and anaerobes. We recommend obtaining peritoneal fluid cultures in CAA, which frequently will lead to a change in the antimicrobial drug therapy guidelines, creating specific recommendations in AA.

Use of New Technologies in the Prevention of Suicide in Europe: An Exploratory Study.

BACKGROUND: New technologies are an integral component of today's society and can complement existing suicide prevention programs. Here, we analyzed the use of new technologies in the prevention of suicide in 8 different European countries. OBJECTIVE: The aim of this paper was to assess the opinions of professionals in incorporating such resources into the design of a suicide prevention program for the region of Zamora in Spain. This investigation, encompassed within the European project entitled European Regions Enforcing Actions against Suicide (EUREGENAS), includes 11 regions from 8 different countries and attempts to advance the field of suicide prevention in Europe. METHODS: Using a specifically designed questionnaire, we assessed the opinions of 3 different groups of stakeholders regarding the use, frequency of use, facilitators, content, and format of new technologies for the prevention of suicide. The stakeholders were comprised of policy and public management professionals, professionals working in the area of mental health, and professionals related to the social area and non-governmental organizations (NGOs). A total of 416 participants were recruited in 11 regions from 8 different European countries. RESULTS: The utility of the new technologies was valued positively in all 8 countries, despite these resources being seldom used in those countries. In all the countries, the factors that contributed most to facilitating the use of new technologies were accessibility and free of charge. Regarding the format of new technologies, the most widely preferred formats for use as a tool for the prevention of suicide were websites and email. The availability of information about signs of alarm and risk factors was the most relevant content for the prevention of suicide through the use of new technologies. The presence of a reference mental health professional (MHP) was also considered to be a key aspect. The countries differed in the evaluations given to the different formats suggesting that the cultural characteristics of the country should be taken into account. CONCLUSIONS: New technologies are much appreciated resources; however they are not often underused in the field of suicide prevention. The results of this exploratory study show that new technologies are indeed useful resources and should be incorporated into suicide prevention programs.

Predictive factors for mortality in Fournier' gangrene: a series of 59 cases.

AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department. METHODS: Retrospective analysis study between 1998 and 2012. RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P=.023), hemoglobin (S 13; D 11; P=.014), hematocrit (S 37; D 31.4; P=.009), white blood cells (S 17,400; D 23,800; P=.023), serum urea (S 58; D 102; P<.001), creatinine (S 1.1; D 1.9; P=.032), potassium (S 3.7; D 4.4; P=.012) and alkaline phosphatase (S 92; D 133; P=.014). Predictive scores: Charlson index (S 1; D 4; P=.013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P=.001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P=.002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P=.004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]). CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described.

[Epiploic appendagitis: a rare cause of abdominal pain]. / Apendagitis epiploica, causa poco frecuente de dolor abdominal.

BACKGROUND: Epiploic appendagitis is an atypical cause of abdominal pain whose knowledge could avoid diagnostic or treatment errors. Diagnosis has been performed with abdominal ultrasound or tomography with the only treatment being nonsteroidal anti-inflammatory drugs. OBJECTIVE: To analyze patients diagnosed in our hospital. METHODS: We performed a 4-year retrospective and descriptive study (March 2009-March 2013) of patients diagnosed with epiploic appendagitis in our hospital. RESULTS: Seventeen patients were included, 14 females and three males with a median age of 57 years. Symptom delay was 72 h. Abdominal pains were located in the left lower quadrant in 64.7% and right lower quadrant in 35.3% of patients. Blood test demonstrated leukocytes 6,300 (5,000-9,500), neutrophils 61.6% (57-65.8), and C reactive protein 1.5 (0.85-2.92). Diagnosis was confirmed with abdominal ultrasound or tomography in 88.2% and intraoperatively in 11.8%. CONCLUSIONS: Epiploic appendagitis was more frequent in women. Abdominal pain was located in the lower quadrant, more predominant in left than right. Blood tests were normal except for increased levels of C-reactive protein. Diagnosis was made mostly preoperatively due to imaging tests, avoiding unnecessary surgical intervention.

ANTECEDENTES: la apendagitis epiploica es una causa poco frecuente de dolor abdominal cuyo conocimiento podría evitar errores diagnósticos y terapéuticos. El diagnóstico suele establecerse mediante ecografía o tomografía abdominal; el tratamiento es sintomático, con antiinflamatorios. OBJETIVO: analizar los casos diagnosticados en nuestro centro. MATERIAL Y MÉTODOS: estudio retrospectivo y descriptivo de pacientes con diagnóstico de apendagitis epiploica durante 4 años (marzo 2009 a marzo 2013). RESULTADOS: se incluyeron 17 pacientes, 14 mujeres y 3 hombres, con una mediana de edad de 57 años. El periodo de latencia de los síntomas fue 72 horas. En 64.7% de los pacientes el dolor abdominal se localizó en el cuadrante inferior izquierdo y en 35.3% en el derecho. Laboratorio: leucocitos 6,300 (5,000-9,500), neutrófilos 61.6% (57- 65.8), proteína C reactiva 1.5 (0.85-2.92). El diagnóstico se confirmó mediante ecografía o tomografía abdominal en 88.2%, e intraoperatorio en 11.8%. CONCLUSIONES: la apendagitis epiploica fue más frecuente en mujeres. La clínica fue dolor abdominal en los cuadrantes inferiores, más frecuente en el lado izquierdo, con RESULTADOS de laboratorio normales, excepto la elevación de la proteína C reactiva. En la mayoría de los casos el diagnóstico se estableció preoperatoriomente, gracias al uso de pruebas radiológicas que evitó las intervenciones quirúrgicas innecesarias.

[Appendiceal diverticulitis: comparative study of 7 cases versus 442 acute appendicitis]. / Diverticulitis apendicular: Estudio comparativo de 7 casos versus 442 apendicitis agudas.

BACKGROUND: Appendiceal diverticulitis (AD) is a rare cause of acute appendicitis (AA) which is most frequently diagnosed after appendectomy in pathological study. OBJECTIVE: To compare AA versus AD. METHODS: Retrospective analytic study in avperiod of 51 months fom January 2009 to March 2013 in the Hospital Universitario San Juan de Alicante (Spain), including patients with clinical or radiological suspicious of acute appendicitis which was confirmed intraoperatively and with the pathological study. RESULTS: We included 449 patients, 442 typical AA (98.5%) and 7AD (1.5%). DA was more frequent in women (57%) with a median age of 44 years old (range 37 to 57 years old), whereas AA was more frequent in men (61%) with a median age of 28 years old (range 15 to 46 years old). Leukocyte count, neutrophils and C-reactive protein were respectively 13,300 per mm3 (range 10,700 to 15,700 per mm3), 87.1% (range 84.6 to 89.6%) and 1.82 mg/dL (range 0.59 to 5.31 mg/dL) in AD versus 14,700 per mm3 (range 12,300 to 17,600 per mm), 81.6% (range 75.1 to 86.4%) and 2.71 mg/dL (range 0.67 to 75 mg/dL) in AA. Alvarado score and appendicitis diagnostic score were respectively 7 (range 6 to 8) and 6 (range 5 to 7) in AD and 7 (range 5 to 7) and 6 (range 5 to 6) in AA. An appendiceal perforation was seen in 3 AD (43%) and 80 AA (18%). CONCLUSION: AD appeared in older patients with a clinical and blood test profile similar to AA but with a higher perforation rate.
