Trend of emergency general surgery procedures during COVID-19 pandemic.

BACKGROUND: In early 2020, the novel coronavirus infection (COVID-19) spread rapidly throughout the whole world, causing a massive response in terms of health resource disposal. Moreover, lockdowns were imposed in entire countries. This study aims to assess whether there was a downward trend in emergency general surgery (EGS) procedures accomplished throughout the COVID-19 pandemic and to determine patients' and diseases' characteristics. METHODS: This is a multicentric retrospective observational cohort analysis conducted on patients who underwent EGS procedures during the lockdown and the same period of the previous year in the three Third Level Hospitals of Friuli Venezia Giulia, Italy. RESULTS: During the study period, 138 patients underwent EGS procedures versus the 197 patients operated on in 2019, meaning a 30.0% decrease in the number of surgeries performed. The incidence rate for EGS procedures was 2.5 surgeries per day during the COVID-19 pandemic compared to 3.5 surgeries per day in 2019 (P<0.001). The characteristics of patients operated on in 2020 were comparable to those of patients who underwent EGS in 2019, except for the higher prevalence of male patients during the COVID-19 pandemic (76.8 vs. 55.8; P<0.001). No difference was recorded in disease severity between the two study periods. CONCLUSIONS: During the COVID-19 pandemic, a significant reduction in EGS procedures carried out was recorded. However, no clear explanation can be given to elucidate this fact.

Can Preoperative Multidetector Computed Tomography Identify Predictive Features of Difficult Native Hepatectomy at Liver Transplantation?

BACKGROUND: Native hepatectomy represents the most demanding surgical step during orthotopic whole liver transplantation (LT). The surgical risk assessment of LT candidates is currently mainly based on clinical and laboratory data, but even preoperative imaging data may be predictive of a complex native hepatectomy. METHODS: A retrospective study on a cohort of 110 LT recipients was conducted. The radiologic variables investigated on pre-LT multidetector computed tomography scan were the length of the retrohepatic inferior vena cava (IVC-L), volume of the dorsal liver sector (DLS-V), complete encirclement of the IVC by the DLS (IVC-CE), max diameter of the native liver (L-D), max diameter of the spleen (S-D), and presence of large spontaneous portosystemic shunts (SPSS). The parameters defining complex native hepatectomy were the operative time, number of red blood cell (RBC) units transfused, IVC replacement technique switch, and post-LT relaparotomy for major bleeding. RESULTS: In a multivariate analysis, the operative time was predicted by hepatocellular carcinoma (HCC) diagnosis (regression coefficient [RC]: 18.237, P = .009), S-D (RC: 3.733, P = .007), and IVC-CE (RC: 20.174, P = .01); the RBC units transfused by an history of gastroesophageal variceal bleeding (RC: 2.503, P = .039), Model for End-Stage Liver Disease (MELD) score (RC: .259, P = .039), and L-D (RC: -0.519, P = .027); the switch to a IVC replacement technique by L-D (odds ratio [OR]: 0.641, P = .028) and IVC-L (OR: 1.065, P = .023); and the relaparotomy for bleeding by L-D (OR: 0.632, confidence interval [CI]: 0.437 to 0.916, P = .015). CONCLUSIONS: Pre-LT multidetector computed tomography (MDCT) seems to be a very useful tool in the surgical risk assessment of LT candidates.

Risk Factors for Graft Loss Due to Acute Vascular Complications in Adult Renal Transplantation Using Grafts Without Vascular Anomalies.

BACKGROUND: Vascular complications are the main cause of early graft loss in renal transplant (RT). A graft with multiple vessels represents the most validated risk factor. The aim of the present study was to identify potential predictive factors for acute vascular complications causing graft loss when graft vascular anomalies are excluded. METHODS: This is a retrospective case-control (1:3 ratio) study extrapolated from the RT series of the Renal Transplant Unit - Udine University Hospital, during the period 1993-2017. Grafts with multiple vessels and retransplant cases were excluded. RESULTS: The overall prevalence of graft loss due to acute vascular complications was 2.6% (25/961). Seventeen complicated recipients had grafts without vascular anomalies (case group). The median time between RT and complication was 6 days (interquartile range, 4-23 days). The following types of vascular complications were recorded: 5 isolated renal artery thromboses (0.5%), 4 isolated renal vein thromboses (0.4%), 4 combined renal artery and vein thromboses (0.3%), 3 renal artery ruptures due to mycotic arteritis (0.3%), and 1 renal artery nonmycotic pseudoaneurysm (0.1%). No differences were recorded between the groups in terms of donors and grafts characteristics. Complicated recipients showed a statistically higher prevalence of thromboembolism history (P = .046) and vascular atherosclerosis (P = .048). During the postoperative course, blood stream infections (P = .02), acute rejection (P = .03), bleeding from a nonmacrovascular source (P = .04), and multiple reintervention because of nonvascular complications (P = .03) were identified as significant risk factors. CONCLUSIONS: Recipient characteristics and post-RT complications rather than donor and graft characteristics are relevant risk factors for graft loss due to acute vascular complications when graft vascular anomalies are excluded.

Does the status of surgical resident compared to that of consultant have an impact on patient's satisfaction over the informed consent process?

OBJECTIVE: The informed consent process is a fundamental element of best practice in the surgical patient's care. The aim of the present study is to investigate the value of informed consent from the patient's perspective in a Teaching Hospital. In particular, the role of the Residents within this process is analyzed to compare their performance with that of Consultants. DESIGN: This is a prospective observational study based on a consecutive cohort of patients who were offered an elective surgical procedure during the period April 2015 - September 2015. SETTING: The study was conducted in the Surgical and Transplantation Unit of the University Hospital of Udine, Italy, accredited by the Joint Commission International. PARTICIPANTS: The study population consisted of 236 patients. The participants were asked on a voluntary basis to fill in a self-evaluating questionnaire after being requested to complete a written informed consent before the operation. RESULTS: In the present study we didn't register any significant difference of patient's satisfaction over informed consent when we evaluated the performance of Residents in comparison to Consultants. CONCLUSIONS: We believe that our positive results may be related to our educational training approach. However, adequate education of Residents about seeking informed consent is not sufficient to guarantee an effective informed consent process if it is not supported as a counterpart by the promotion of correct and positive patient knowledge and perception of the Residents' skills, clinical role and responsibilities.
