SummaryBackgroundSurgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.MethodsThis international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.FindingsBetween Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001).InterpretationCountries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.FundingDFID-MRC-Wellcome Trust Joint Global Health Trial Development Grant,...
Resumen A nivel de la línea media de la pared anterior del abdomen existen comúnmente ciertos defectos parietales, ellos son: las hernias umbilicales, las hernias epigástricas y la diástasis de los rectos. La técnica de MILOS (mini and Less Open sublay) permite una reparación de estos defectos con la colocación de un material protésico en el espacio pre peritoneal retro muscular (sub lay) con buenos resultados.Con el objetivo de valorar los resultados de la aplicación de esta técnica se presenta este estudio observacional descriptivo prospectivo sobre pacientes adultos de ambos sexos, portadores de defectos primarios de la línea media sometidos a tratamiento quirúrgico con técnica de MILOS de marzo a noviembre del
RESUMENIntroducción: La técnica cerrada es cada vez mas utilizada en el tratamiento quirúrgico del quiste pilonidal, ya que es simple, con periodo de corto tiempo quirúrgico, hospitalización y cicatrización, aunque en nuestro medio aún no sea la mas utilizada.Objetivo: Describir la experiencia del tratamiento del quiste pilonidal con la técnica cerrada con colgajo de avance en nuestro servicio.Materiales y método: El trabajo presenta un diseño observacional, descriptivo de corte transversal. Se estudió 30 pacientes de ambos sexos con diagnóstico de quiste pilonidal, intervenidos quirúrgicamente con la técnica cerrada con colgajo de avance en la II Cátedra de Clínica Quirúrgica del Hospital de Clínicas en el periodo enero 2014 a enero 2017.Resultados: 30 pacientes, edad promedio: 27,4 con rango entre 17 a 41 años, de los cuales el 70% (21) eran del sexo masculino y 30% (9) del sexo femenino, el promedio del tiempo quirúrgico fue 39 min y la estancia hospitalaria de 6 a 12 horas post quirúrgicas, el 90% (27) de los pacientes no presentó complicación alguna, presentando buena cicatrización en 15 días, la morbilidad fue del 10% (2 infecciones del sitio quirúrgico y 1 hematoma) y mortalidad nula.Discusión: En el trabajo de Karydakis, la edad promedio fue de 24,5 años en el nuestro de 27,4; el 53% fue hombre, en el nuestro 70%; la hospitalización promedio fue de 2,5 días, el nuestro de 6 a 12 horas. La recuperación completa de la mayoría fue de 15 días en ambos trabajos.Palabras claves: quiste pilonidal, colgajo de avance. SUMMARYIntroduction: The closed techinique is one of the most used in the surgical treatment of the pilonidal cyst, because it is simple and reproductible, it presents a period of short surgical time, of hospital stay and cicatrizacion.Objective: to describe experience of treatment of the pilonidal cyst with the closed flap technique in our service. (21) were male, and 30% (9) were female, the average surgical time was 39 minutes, and the avarege hospital stay was 6 to 12 hours post surgical procedure, 90%(27) of the patients did not present any complications, prsenting good healing in an average of 15 days, the morbidity was 10% (2 surgical site infections and 1 hematoma), and mortality was null. MANejoDiscussion: in a Word of Karydakis obtained similar results to our work, the average age was 24,5 years in our 27,4; the 53% was a man, in our 70%; the average hospitalization was 2,5 days, in our 6 to 12 hour period. The complete recovery of the major-ity of the patients was of 15 days in both works.Keywords: Pilonidal Cyst, Closure flap technique. INTRODUCCIÓNEl quiste pilonidal es un proceso infeccioso que se produce en la hendidura del surco interglúteo(1), que afecta con mayor frecuencia a varones con una relación 3:1, rara vez ocurre antes de la pubertad y después de la tercera década(2).Tiene varias teorías, primero se propuso la teoría congé-nita, luego la adquirida(3,4).Aunque se ha definido como quiste, las cavidades pilonidales no son verdaderos quistes, ya que tienen revestimiento epitel...
