    A pure sensory neuronopathy (also referred to as a sensory ganglionopathy) is one of a handful of classical neurological paraneoplastic syndromes. Current guidelines recommend that in cases of sensory neuronopathy, a search for an underlying malignancy be pursued for up to 4 years. We report the case of a 52-year-old woman with a sensory neuronopathy who was eventually diagnosed with a cholangiocarcinoma 6 years after the onset of her disease. A CT fluorodeoxyglucose positron emission tomography (FDG-PET) scan performed 18 and 24 months after disease onset failed to identify an underlying neoplasm. Immunomodulatory treatment with corticosteroids, intravenous immunoglobulins and plasma exchange were ineffective. Investigations for Sjogren's disease were negative. A third FDG-PET performed 6 years after symptom onset identified a cholangiocarcinoma, which was confirmed histologically following open resection. Since the tumour was removed, our patient's condition has not progressed, but there has been no improvement and she remains severely disabled

    Introduction: Too small or too big liver grafts for recipient's size has detrimental effects on transplant outcomes. Research Questions: The purpose was to correlate donor-recipient body surface area (BSA) ratio or BSA index (BSAi) with recipient survival, graft survival, hepatic artery or portal vein, or vena cava thrombosis. High and low BSAi cut-off points were determined. Design: There were 11,245 adult recipients of first deceased donor whole liver-only grafts performed in the UK from January 2000 until June 2020. The transplants were grouped according to the BSAi and compared to complications, graft and recipient survival. Results: The BSAi ranged from 0.491 to 1.691 with a median of 0.988. The BSAi > 1.3 was associated with a higher rate of portal vein thrombosis within the first 3 months (5.5%). This risk was higher than size-matched transplants (OR: 2.878, 95% CI: 1.292-6.409, P = 0.01). Overall graft survival was worse in transplants with BSAi ≤ 0.85 (HR: 1.254, 95% CI: 1.051-1.497, P = 0.012) or BSAi > 1.4 (HR: 3.704, 95% CI: 2.029-6.762, P 1.4. These findings were confirmed by bootstrap internal validation. No statistically significant differences were detected for hepatic artery thrombosis, occlusion of hepatic veins/inferior vena cava or recipient survival. Conclusions: Donor-recipient size mismatch affects the rates of portal vein thrombosis within the first 3 months and overall graft survival in deceased-donor liver transplants

    Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

    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

    Background: Splenic salvage is the ultimate goal of the treatment for splenic injury. We experimentally investigated a spleen salvage technique after spleen injury using radiofrequency ablation technology. Methods: A grade IV spleen trauma was produced in 10 white male Landrace pigs (the lower pole of the spleen was sharply divided at the level where the lower hilar vessel enters the organ) under general anesthesia. A Radionics Cooltip Radio Frequency needle was used to stop the bleeding in every case. The electrode was inserted in four to six different sites and each session lasted for 2 to 6 minutes. Results: All bleeding sites were controlled intraoperatively with no additional means. Postoperatively, all animals appeared clinically healthy, and at the time the animals were killed, no blood, pus, or other fluid was identified in the abdomen or chest. Subcapsular or perisplenic hematomas were not found either. Conclusion: We believe that radiofrequency ablation may be used in splenic injury to stop bleeding, especially when blood transfusion or surgery is indicated. This procedure may reduce the frequency of open surgery for repair of the injury, the number of splenectomies, and the amount of blood transfusion required. The advantage of use under ultrasound or computed tomographic guidance or laparoscopically makes it even more appealing. Thus, we suggest that further study in human subjects is required to validate our results

    Pancreaticojejunostomy Versus Pancreaticogastrostomy After Pancreaticoduodenectomy: An Up-to-date Meta-Analysis

    No full text
    Background: The reconstruction of the pancreas after pancreaticoduodenectomy (PD) is a crucial factor in preventing postoperative complications as pancreatic anastomosis failure is associated with a high morbidity rate and contributes to prolonged hospitalization and mortality. Several techniques have been described for the reconstruction of pancreatic digestive continuity in the attempt to minimize the risk of a pancreatic fistula. The aim of this study was to compare the results of pancreaticogastrostomy and pancreaticojejunostomy after PD. Methods: A systematic review and meta-analysis were conducted of randomized controlled trials (RCTs) published up to January 2015 comparing patients with pancreaticogastrostomy (PG group) versus pancreaticojejunostomy (PJ group). Two reviewers independently assessed the eligibility and quality of the studies. The meta-analysis was conducted using either the fixed-effect or the random-effect model. Results: Eight RCTs describing 1,211 patients were identified for inclusion in the study. The meta-analysis shows that the PG group had a significantly lower incidence rate of postoperative pancreatic fistulas [OR 0.64 (95% confidence interval 0.46–0.86), p =.003], intra-abdominal abscesses [OR 0.53 (95% CI, 0.33–0.85), p =.009] and length of hospital stay [MD −1.62; (95% CI 2.63–0.61), p =.002] than the PJ group, while biliary fistula, mortality, morbidity, rate of delayed gastric emptying, reoperation, and bleeding did not differ between the two groups. Conclusion: This meta-analysis suggests that the most effective treatment for reconstruction of pancreatic continuity after pancreatoduodenectomy is pancreaticogastrostomy. However, the advantage of the latter could potentially be demonstrated through further RCTs, including only patients at high risk of developing pancreatic fistulas

    BACKGROUND: Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary complications in patients undergoing elective cancer surgery. METHODS: This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020. Patients suspected of SARS-CoV-2 infection before operation were excluded. The primary outcome measure was postoperative pulmonary complications at 30 days after surgery. Preoperative testing strategies were adjusted for confounding using mixed-effects models. RESULTS: Of 8784 patients (432 hospitals, 53 countries), 2303 patients (26.2 per cent) underwent preoperative testing: 1458 (16.6 per cent) had a swab test, 521 (5.9 per cent) CT only, and 324 (3.7 per cent) swab and CT. Pulmonary complications occurred in 3.9 per cent, whereas SARS-CoV-2 infection was confirmed in 2.6 per cent. After risk adjustment, having at least one negative preoperative nasopharyngeal swab test (adjusted odds ratio 0.68, 95 per cent confidence interval 0.68 to 0.98; P = 0.040) was associated with a lower rate of pulmonary complications. Swab testing was beneficial before major surgery and in areas with a high 14-day SARS-CoV-2 case notification rate, but not before minor surgery or in low-risk areas. To prevent one pulmonary complication, the number needed to swab test before major or minor surgery was 18 and 48 respectively in high-risk areas, and 73 and 387 in low-risk areas. CONCLUSION: Preoperative nasopharyngeal swab testing was beneficial before major surgery and in high SARS-CoV-2 risk areas. There was no proven benefit of swab testing before minor surgery in low-risk areas
