Non-enhanced abbreviated MRI as a periodic surveillance protocol for colorectal liver metastases compared with contrast-enhanced CT: a prospective observational study.

Background: Adopting appropriate noninvasive radiological method is crucial for periodic surveillance of liver metastases in colorectal cancer (CRC) patients after surgery, which is closely related to clinical management and prognosis. This study aimed to prospectively enroll stage II-III CRC patients for the surveillance of liver metastases, and compare the diagnostic performance of contrast-enhanced CT (CE-CT) and non-enhanced abbreviated MRI (NE-AMRI) during this process.
Methods: 587 CRC patients undergoing radical resection of the primary tumor were evaluated by 1 to 3 rounds of surveillance tests, consisting of abdominal CE-CT and contrast-enhanced MRI (CE-MRI) within 7 days at 6-month intervals.

Thoracoscopic right upper lobectomy is a demanding procedure especially in case of hilar adhesions. Herein, we reported a simple technique as the simultaneous ligation of hilar structures to facilitate thoracoscopic right upper lobectomy. After resections of fissures and of hilar lymph nodes, the following structures were sequentially isolated and simultaneously resected in their natural position: V2+A2 vessels; right upper bronchus; and V1+V3+A1+A3 vessels.

Introduction: Altered vascular microcirculation is recognized as a risk factor for anastomotic leakage (AL) in colorectal surgery. However, few studies evaluated its impact on AL using different devices, with heterogeneous results. The present study reported the initial experience measuring gut microcirculatory density and flow with the aid of incidence dark-field (IDF) videomicroscopy (Cytocam, Braedius, Amsterdam, The Netherlands) comparing its operative outcome using a propensity score matching (PSM) model based on age, gender, and Charlson Comorbidity Index (CCI).

Background: The two-stage surgical technique of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) enables extensive liver resection and promotes future liver remnant regeneration (FLR), in part by inhibiting the Hippo signalling pathway. Its main effector, Yes-associated protein (YAP), has low intrinsic transcriptional activity and requires the transcription enhanced associated domain factor (TEAD) family members as cofactors for target gene transcription. We evaluated the intracellular localization and expression of TEAD1-4, hypothesized to regulate the activity of YAP and, consequently, liver regeneration.

Papillary fibroelastomas (PFEs) are rare, benign, primary cardiac tumors, typically found on the valve surfaces and more commonly on the left side of the heart, with occurrences in the right atrium even rarer. In this case, a highly mobile tumor was incidentally detected in the right atrium of an 83-year-old woman with advanced right lung cancer during preoperative transthoracic echocardiography and magnetic resonance imaging. Although the patient was asymptomatic and of advanced age, the tumor's high mobility warranted resection.
