    During the care of patients with novel coronavirus infection at the Lomonosov MSU Medical Research and Education Center from April 21 to June 13, 2020, we observed cases of spontaneous mediastinal emphysema (spontaneous pneumomediastinum) as a manifestation or a probable complication of COVID-19.The aim of the paper. To provide clinical case descriptions and approaches to the management of patients with spontaneous pneumomediastinum in COVID-19 associated pneumonia, as they are not addressed in the current clinical guidelines, and therefore are worthy of special attention.Among 224 patients with laboratory-confirmed diagnosis of the novel coronavirus infection COVID-19, five cases of pneumomediastinum without pneumothorax were identified. Of these, in two cases the pneumomediastinum developed during noninvasive lung ventilation (NLV) (one case) and invasive lung ventilation (one case). In three cases, spontaneous mediastinal emphysema was not associated with lung ventilation. By the time of publication, one case of pneumomediastinum was completed, and four patients remained hospitalized. All five patients were males aged from 52 to 84 years.This paper presents in depth the description of two cases of mediastinal and subcutaneous emphysema in patients with COVID-19

    PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

    Technique of the laparoscopic pelvic exenteration

    No full text
    Background: Laparoscopic surgery has proved itself to be a “golden standard” for treatment of most abdominal and retroperitoneal cancers. Such a serious procedure as pelvic exenteration continues to be a complex surgical intervention usually performed through a  conventional laparotomic access. However, studies on minimally invasive approach for this intervention have becoming increasingly published in the world literature.Aim: To describe the laparoscopic pelvic exenteration technique of pelvic exenteration, as well as to assess short- and long-term results of these interventions.Materials and methods: From 2011 to 2018, 21 procedures of laparoscopic pelvic exenteration have been performed in 6  surgical centers (Moscow, Russia). Six (6) patients had previously confirmed cervical cancer, 7 patients had bladder cancer, 4 patients had rectal cancer, 1 patient had vaginal cancer, 2 patients had relapsing vaginal cancers after previous uterine extirpation, and 1 patient had an ovarian neoplasm.Results: The laparoscopic pelvic exenteration volumes were as follows: 9  total, 7 anterior and 5 posterior procedures. In 19 out of 21 cases, negative resection margin (R0) was possible. Median duration of the procedure was 254 minutes, median blood loss was 515 ml, and median postoperative hospital stay was 13 days. Postoperative complications were registered in 6 (28.6%) patients. The 3-year overall survival was 85.71%.Сonclusion: The choice of laparoscopic access can reduce blood loss, decrease the rates of early postoperative complications, contributes to a more comfortable postoperative period with early activation and less severe pain syndrome, and leads to a reduction in the duration of hospital stay. These results of the laparoscopic technique are comparable with those of laparoscopic and open pelvic exenteration published by other authors

    Aim: This study aimed to describe the change in surgical practice and the impact of SARS-CoV-2 on mortality after surgical resection of colorectal cancer during the initial phases of the SARS-CoV-2 pandemic. Method: This was an international cohort study of patients undergoing elective resection of colon or rectal cancer without preoperative suspicion of SARS-CoV-2. Centres entered data from their first recorded case of COVID-19 until 19 April 2020. The primary outcome was 30-day mortality. Secondary outcomes included anastomotic leak, postoperative SARS-CoV-2 and a comparison with prepandemic European Society of Coloproctology cohort data. Results: From 2073 patients in 40 countries, 1.3% (27/2073) had a defunctioning stoma and 3.0% (63/2073) had an end stoma instead of an anastomosis only. Thirty-day mortality was 1.8% (38/2073), the incidence of postoperative SARS-CoV-2 was 3.8% (78/2073) and the anastomotic leak rate was 4.9% (86/1738). Mortality was lowest in patients without a leak or SARS-CoV-2 (14/1601, 0.9%) and highest in patients with both a leak and SARS-CoV-2 (5/13, 38.5%). Mortality was independently associated with anastomotic leak (adjusted odds ratio 6.01, 95% confidence interval 2.58–14.06), postoperative SARS-CoV-2 (16.90, 7.86–36.38), male sex (2.46, 1.01–5.93), age >70 years (2.87, 1.32–6.20) and advanced cancer stage (3.43, 1.16–10.21). Compared with prepandemic data, there were fewer anastomotic leaks (4.9% versus 7.7%) and an overall shorter length of stay (6 versus 7 days) but higher mortality (1.7% versus 1.1%). Conclusion: Surgeons need to further mitigate against both SARS-CoV-2 and anastomotic leak when offering surgery during current and future COVID-19 waves based on patient, operative and organizational risks
