Disparate reporting of SSIs makes direct cost comparisons difficult, but this review indicated that SSIs are extremely costly. Thus, rigorous procedures must be implemented to minimize SSIs. More economic and QoL studies are required to make accurate cost estimates and to understand the true burden of SSIs.

Cytokines are polypeptides produced mainly by activated leucocytes in response to infection and injury, including surgical trauma. Several reports have described the systemic cytokine response to a surgical operation, some of them in a sequential way1,2. This study was designed to determine the peritoneal and systemic cytokine response to elective abdominal surgery during the first 72 h after operation.

Since laparoscopic cholecystectomy has become the standard procedure for the treatment of gallstone disease, several cases have been reported in patients with situs inversus. These cases require more technically demanding procedures due to the symmetrical disposition of the anatomy. Thus, handedness could influence the performance of these operations. The two of us (L.M.O.) and (J.M.B.), a right-handed and a left-handed surgeon, respectively, placed the instruments in reverse mode from that used in orthotopic patients. The right-handed surgeon felt more impairment when dissecting with his left hand and decided to cross the instruments within the abdomen. The left-handed surgeon was able to alternate the performance of the dissection maneuvers between the right and left hands. Surgical procedures are apparently designed for right-handed surgeons and can be approached by the left-handed in alternative ways. In fact, the accommodation of laparoscopic cholecystectomy to left-handedness has been described in the literature. The rare opportunity to operate in a symmetrical way allows the right-handed surgeon to understand the absence of comfort and ergonomy often experienced by left-handed colleagues.

BackgroundOrgan-space surgical site infections (SSI) are the most serious and costly infections after colorectal surgery. Most previous studies of risk factors for SSI have analysed colon and rectal procedures together. The aim of the study was to determine whether colon and rectal procedures have different risk factors and outcomes for organ-space SSI.MethodsA multicentre observational prospective cohort study of adults undergoing elective colon and rectal procedures at 10 Spanish hospitals from 2011 to 2014. Patients were followed up until 30 days post-surgery. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Oral antibiotic prophylaxis (OAP) was considered as the administration of oral antibiotics the day before surgery combined with systemic intravenous antibiotic prophylaxis.ResultsOf 3,701 patients, 2,518 (68%) underwent colon surgery and 1,183 (32%) rectal surgery. In colon surgery, the overall SSI rate was 16.4% and the organ-space SSI rate was 7.9%, while in rectal surgery the rates were 21.6% and 11.5% respectively (p < 0.001). Independent risk factors for organ-space SSI in colon surgery were male sex (Odds ratio -OR-: 1.57, 95% CI: 1.14–2.15) and ostomy creation (OR: 2.65, 95% CI: 1.8–3.92) while laparoscopy (OR: 0.5, 95% CI: 0.38–0.69) and OAP combined with intravenous antibiotic prophylaxis (OR: 0.7, 95% CI: 0.51–0.97) were protective factors. In rectal surgery, independent risk factors for organ-space SSI were male sex (OR: 2.11, 95% CI: 1.34–3.31) and longer surgery (OR: 1.49, 95% CI: 1.03–2.15), whereas OAP with intravenous antibiotic prophylaxis (OR: 0.49, 95% CI: 0.32–0.73) was a protective factor. Among patients with organ-space SSI, we found a significant difference in the overall 30-day mortality, being higher in colon surgery than in rectal surgery (11.5% vs 5.1%, p = 0.04).ConclusionsOrgan-space SSI in colon and rectal surgery has some differences in terms of incidence, risk factors and outcomes. These differences could be considered for surveillance purposes and for the implementation of preventive strategies. Administration of OAP would be an important measure to reduce the OS-SSI rate in both colon and rectal surgeries.

There is a pronounced systemic response to hepatic resection under total vascular exclusion that is reflected by the increase in IL-6 concentration and correlates with the operative blood loss and postoperative outcome. This might be used as an indicator of the response to specific treatments in this type of surgery. Treatments that minimise the IL-6 response to major hepatic resection may be of value.

Ante la pandemia por SARS-CoV-2 resulta fundamental conocer los aspectos claves de la infecció n: su origen epidemioló gico, presentació n, curso clínico, diagnó stico y los tratamientos empleados (aú n experimentales en muchos casos). El conocimiento sobre el virus es limitado, pero a medida que progresa la pandemia y se conoce má s su fisiopatología se está publicando nueva evidencia de forma masiva. Los especialistas quirú rgicos se enfrentan a una situació n sin precedentes: deben colaborar en plantas mé dicas o urgencias atendiendo a estos pacientes, y ademá s tomar decisiones sobre pacientes quirú rgicos con posible COVID-19. Esta revisió n narrativa pretende resumir los aspectos má s relevantes y sintetizar los conceptos bá sicos sobre COVID-19 para los cirujanos.
