AI Article Synopsis

  • Ovarian neoplasms pose significant health risks for women, necessitating accurate categorization as benign, borderline, or malignant for effective surgical management.
  • This study evaluated the clinical advantages of intraoperative frozen section analysis in diagnosing adnexal masses suspected of being ovarian cancer by reviewing results from 106 cases.
  • The frozen section proved to be 93.3% accurate overall, but with varying sensitivities, particularly struggling with borderline and mucinous tumors, highlighting its strengths and limitations in diagnosing ovarian tumors.

Article Abstract

Background: Ovarian neoplasms are an important cause of morbidity and mortality in women. The surgical management of ovarian neoplasms depends on their correct categorisation as benign, borderline and malignant.

Aim: The aim of this study was to determine the clinical benefits of intraoperative frozen section analysis into the surgical management policy of women referred with an adnexal mass suspicious of ovarian cancer.

Methods: A retrospective study of 106 ovarian frozen section results was examined to determine the accuracy of frozen section diagnosis. The accuracy, sensitivity, specificity, and positive and negative predictive value of frozen section were studied.

Results: The overall accuracy to determine the status of malignancy was 93.3%. Sensitivity of the test was highest in the benign groups at 97.4% and lowest in the borderline groups at 25%. The accuracy of frozen section was 80% in serous tumours and 60% in mucinous. There were two (2.5%) false positive, three (10.7%) false negative and two overestimated diagnosis in frozen section examination. Eight malignancies (30.7%) were of metastatic origin, all of which (100%), were correctly identified on frozen section.

Conclusion: Frozen section appears to be an accurate technique for the histopathological diagnosis of ovarian tumours. Some limitations were observed among borderline and mucinous tumours. This emphasises the great value of frozen section in the diagnosis of ovarian tumours.

Background: As hypothermic circulatory arrest (HCA) is being more frequently induced in patients undergoing aortic arch surgery, its safety at different degrees has become a crucial area of study. The aim of this study was to assess the surgical outcomes of mild hypothermic circulatory arrest (MI-HCA) during aortic arch surgery.

Methods: Acute type A aortic dissection (ATAAD) patients who underwent total arch replacement (TAR) and frozen elephant trunk (FET) surgery between January 2014 and December 2023 were enrolled in this study.

Brain biopsy is commonly employed for the histological diagnosis of complex intracranial diseases. To improve the positive diagnostic rate, the precision of intraoperative tissue sampling is critical. This study evaluated the accuracy of fluorescence imaging technology in rapidly distinguishing tumours from nontumour tissue during surgery, thus providing real-time feedback to surgeons and optimizing the surgical workflow.

Purpose: Precise tumor excision is important in breast-conserving surgery (BCS). This study explores the safety and accuracy of fluorescence image-guided BCS (FIGS) using a lidocaine mucilage-ICG compound (L-ICG).

Methods: 54 patients who underwent BCS from August 2020 to September 2023 were enrolled.

Objectives: In this study, the spread of methylene blue was compared between an ultrasound-guided Pericapsular Nerve Group (PENG) block and a double injection technique, where the approach towards the inferomedial acetabulum was added to the latter.

Methods: The two techniques were performed in 11 fresh frozen cadavers. The spread was measured after anatomical dissection in which the supplying femoral and obturator nerves were identified.

Cryo-electron tomography (cryo-ET) is confronted with the intricate task of unveiling novel structures. General class discovery (GCD) seeks to identify new classes by learning a model that can pseudo-label unannotated (novel) instances solely using supervision from labeled (base) classes. While 2D GCD for image data has made strides, its 3D counterpart remains unexplored.
