Objectives: Thoraco-dorsal artery perforator (TDAP) flaps have been increasingly used in breast and soft tissue reconstruction. Perforator localization is often done using a hand-held doppler, however, false results are not uncommon. This study aimed to systematically review the literature on the value of preoperative computed tomographic angiography (CTA) in TDAP flaps examining scanning protocol, mapping technique, concordance with operative findings, and disadvantages., Methods: A PRISMA-compliant comprehensive search of Medline, Embase, Cochrane Library, and CINAHL databases was conducted in November 2023. We included studies evaluating CTA mapping of free and pedicled TDAPs for breast or soft tissue reconstruction using The Joanna Briggs Institute (JBI) Critical Appraisal Tools., Results: Five studies were included and considered at high risk of bias. The studies included 72 patients with a mean age of 43.8 years. Concordance between CT findings and Doppler mapping or operative visualization was reported in two studies. In three studies, CTA was combined with Doppler flowmetry, whilst dynamic infrared thermography was used in one study. Standardized scanning protocol and patient positioning were lacking in all reports., Conclusions: This study highlights the paucity of evidence on the value of CTA in TDA perforator mapping with inconsistent outcomes and non-standardized scanning protocols. Despite difficult imaging acquisition and interpretation, 3D reconstructed images and detailed vascular anatomy may facilitate planning., Advances in Knowledge: Further research is required to explore the practical value of CTA in TDAP planning and standardizing protocols., (© The Author(s) 2024.

Background: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group., Methods: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α., Results: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer., Conclusion: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer., (© The Author(s) 2024.
