Background: Despite improved revascularization options, many patients with chronic limb-threatening ischemia (CLI) require lower limb amputation. Duplex ultrasound (DUS) is recommended as first-choice imaging technique in CLI. However, the prognostic utility of DUS for planning lower limb amputations has never been described before. This study aims to evaluate if DUS and findings from physical examination could be used to help predict the best level of lower limb amputation in patients with CLI., Methods: A retrospective cohort of 124 patients with CLI and a lower limb amputation was analyzed. Outcome measurements were reoperation, revision, and conversion rates, which were related to findings from physical examination and DUS examinations., Results: Thirty-nine reoperations were performed, of which 17 stump revisions and 22 conversions were from below- to above-knee amputation. There was a discrepancy in findings of physical examination and DUS of 25% and 64% of femoral and popliteal pulsations respectively. Conversion rates increased with a more proximal occlusion on DUS. All patients with a vascular occlusion in the aortoiliac trajectory or deep femoral artery required a higher amputation level., Conclusions: Physical examination seems to be unreliable, and therefore should not be used to assess the optimal level of lower extremity amputation. Performing a primary above-knee amputation in patients with vascular occlusion in the aortoiliac trajectory or deep femoral artery could significantly reduce reoperation rates., (Copyright © 2020 Elsevier Inc.

Background: Worldwide, acute cholecystitis is a common disease. The current standard of treatment is according to the Tokyo Guidelines established in 2018. Conservative management with various combinations of analgesics, anti-inflammatory drugs, and percutaneous drainage are sometimes used to avoid or delay surgery, especially in frail patients, but little is known about the efficacy and safety of these strategies. Therefore, we evaluated the effect of antibiotic agents, with or without gallbladder drainage, or symptomatic treatment alone in patients with acute cholecystitis who were considered unfit for acute surgery. Patients and Methods: All patients whose initial treatment for cholecystitis was conservative who were admitted between 2014 and 2016 were included in this study. Patients were divided into three groups: those treated with antibiotic agents, those who received antibiotic agents in combination with percutaneous gallbladder drainage and those whose treatment was only symptomatic. Demographic characteristics, comorbidities, Tokyo Severity Classification, length of stay, re-admission rates, secondary treatment (delayed drainage or surgery), and complication rates were retrieved from their medical records. Results: Initially 33 were treated with conservative methods in this period. Fifteen patients were treated initially with antibiotic agents, 12 patients with antibiotic agents in combination with percutaneous drainage, and 6 patients received symptomatic treatment only. One patient had mild cholecystitis (Tokyo Severity Classification grade I) and the other 32 patients had moderate to severe (grade II or III) cholecystitis. Eventually, 25 patients (76%) underwent cholecystectomy, 2 of whom (8%) were emergency operations because of disease progression. Twelve patients (36%) were re-admitted, of whom the majority (83%) was re-admitted before cholecystectomy. Conclusion: Treatment of cholecystitis with antibiotic agents, drainage, or analgesic agents is feasible. However, it should be regarded as a bridge to surgery rather than a definitive solution because of frequent recurrence. Occasionally, an emergency operation could not be avoided as a result of disease progression under conservative treatment.
