▪ RESUMO Introdução: Abdominoplastia é um dos procedimentos cirúrgicos estéticos mais realizados. Seroma é a complicação local mais comum associada com abdominoplastia, com uma incidência média de 10%. A maior incidência de seroma pós-operatório (PO) ocorre no décimo primeiro dia PO. Ecografia abdominal é o método de escolha para o diagnóstico de seroma após abdominoplastia. Novas técnicas surgiram ao longo dos anos na tentativa de trazer melhores resultados estéticos com menos complicações, como lipoabdominoplastia descrita por Saldanha. Porém, estudos anatômicos recentes questionam a necessidade da manutenção da fáscia de Scarpa descrita na técnica de lipoabdominoplastia, descrevendo que em torno de 90% do sistema linfático abdominal está no plano subdérmico e 10% em um sistema linfático profundo justa-aponeurose abdominal. O objetivo é comparar a incidência de seroma na lipoabdominoplastia sem preservação da fáscia de Scarpa com a abdominoplastia clássica. Métodos: Coorte prospectiva, cega na qual serão analisados 40 pacientes consecutivos que realizaram abdominoplastia sem lipoaspiração associada (n = 20) ou lipoabdominoplastia (n = 20) no Hospital de Clínicas de Porto Alegre entre abril de 2016 e maio de 2017. Todos foram submetidos à ecografia de parede abdominal no 10o dia PO. Resultados: A incidência de seroma foi de 5% (n = 1) no grupo de abdominoplastia clássica e de 10% (n = 2) no grupo de lipoabdominoplastia, sem diferença estatística. Conclusão: Estes resultados, neste grupo de pacientes, mostram que não houve diferença estatística entre os dois grupos. ▪ ABSTRACT Introduction: Abdominoplasty is among the most commonly performed surgical procedures. Seroma is the most common local complication associated with abdominoplasty, with an average incidence of 10%. The highest incidence of postoperative (PO) seroma occurs on the eleventh postoperative day (POD). Abdominal ultrasound is the method of choice for diagnosing seroma after abdominoplasty. New techniques have emerged aiming to improve aesthetic results with fewer complications, such as lipoabdominoplasty described by Saldanha. However, recent anatomical studies have questioned the need for Scarpa fascia preservation recommended in the lipoabdominoplasty technique, describing that around 90% of the abdominal lymphatic system is in the subdermal plane, while the other 10% is in a deep lymphatic system near the abdominal aponeurosis. The objective is to compare the incidence of seroma in lipoabdominoplasty without Scarpa fascia preservation to that in classic abdominoplasty. Methods: Prospective blinded cohort in which 40 consecutive patients who underwent abdominoplasty without associated liposuction (n = 20) or lipoabdominoplasty (n = 20) at the Hospital de Clínicas of Porto Alegre between April 2016 and May 2017 were analyzed. All patients underwent abdominal wall ultrasonography on the tenth POD. Results: The incidence of seroma was 5% (n = 1) in the classic abdominoplasty group and 10% (n = 2) in the lipoabdominoplasty group, with no statistical difference. Conclusion: These results showed no statistically significant intergroup difference in seroma development.

Objective: The influence of age on the malignant cytology rate of thyroid nodules remains uncertain. The American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) is currently used to guide subsequent investigations of thyroid nodules, regardless of clinical variables. This study aimed to investigate the impact of age on the malignant cytology rates of thyroid nodules and the diagnostic performance of ACR TI-RADS across different age groups. Design: A retrospective, single-center, observational study. Methods: Patients aged ≥ 20 years with thyroid nodules, who underwent fine-needle aspiration biopsy between 2012 and 2019 were evaluated. Ultrasound images were used to obtain the TI-RADS data. Malignancy was determined based on suspicious for malignancy (Bethesda V) and malignant (Bethesda VI) cytology results or malignancy in cell block analysis. Results: A total of 1023 nodules from 921 patients (88.2% female) were analyzed. The median age was 58.5 (interquartile range [IQR], 41.1-66.6) years, and the median nodule size was 2.4 (IQR, 1.7-3.6) cm. Stratification by age revealed a decreasing prevalence of malignant cytology across subgroups of 20-39, 40-59, and ≥60 years (10.7%, 8.5%, and 3.7%, respectively; P = .002). After adjusting for sex, multinodularity, nodule size, and ACR TI-RADS category, we observed that each year of age reduced the OR for malignant cytology by 3.0% (95% CI: 0.7%-5.3%; P = .011). When comparing the subgroups of 20-39 and ≥60 years, the malignant cytology rate decreased by half in TI-RADS 4 (from 21.4% to 10.4%) and two-thirds in TI-RADS 5 (from 64.7% to 22.6%). Conclusions: Our study demonstrated that as patient age increased, the rate of malignant cytology in thyroid nodules decreased. Moreover, age significantly influences the malignancy rates of thyroid nodules classified according to the ACR TI-RADS. [ABSTRACT FROM AUTHOR]

Background: The most frequent site of recurrence of differentiated thyroid cancer (DTC) is cervical lymph nodes (LNs), which often necessitates repeated surgical interventions and morbidity in a generally indolent disease. Data on active surveillance (AS) of small cervical nodal metastasis are still scarce, particularly in real-world clinical settings. In this study, we evaluated the DTC outcomes of AS of metastatic cervical LNs and explored factors associated with disease progression. Methods: We conducted a retrospective cohort study, including DTC patients with biopsy-proven metastatic cervical LNs, who were followed on AS in a tertiary care, university-based institution in Brazil. The inclusion criteria were cervical metastasis ≤2.0 cm and an AS duration of at least 6 months. We excluded lesions with aggressive histology, those in close proximity to or invading local structures. The primary outcome was disease progression (enlargement ≥3 mm in any diameter or a new cervical metastasis). Results: Data from 40 patients were analyzed. Most were female (77.5%) and had papillary thyroid cancer (97.5%). The mean age was 47.0 (± standard deviation 15.8) years. The 8th edition of the tumor, node, metastasis stage (TNM8) staging for DTC was as follows: 29 in stage I (74.4%), 8 in stage II (20.5%), and 2 in stage IV (5.0%). The median maximum LN diameter was 0.9 (interquartile range [IQR], 0.8–1.3) cm, and the median AS follow-up duration was 27.5 (IQR, 16.5–47.3) months. Disease progression occurred in 14 (35%) patients: 7 (17.5%) due to enlargement ≥3 mm, and 7 (17.5%) had new cervical metastasis. The cervical progression-free survival was 51.0 (confidence interval, 47.0–55.0) months. No demographic, oncological, or biochemical factors were associated with disease progression. Of the 14 patients with disease progression, 8 were referred for surgery. No permanent surgical complications were reported. Of the six patients who remained on AS despite disease progression, five showed no further progression during subsequent follow-up (range 6–40 months). Conclusions: We observed that most small metastatic cervical LNs remained stable and were safely managed with AS. Nevertheless, these observations are limited by the retrospective design, small sample size, and short follow-up. Further prospective and long-term studies are warranted. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Hepatocellular carcinoma (HCC) is an aggressive malignant neoplasm that requires liver transplantation (LT). Despite patients with HCC being prioritized by most organ allocation systems worldwide, they still have to wait for long periods. Locoregional therapies (LRTs) are employed as bridging therapies in patients with HCC awaiting LT. Although largely used in the past, transarterial embolization (TAE) has been replaced by transarterial chemoembolization (TACE). However, the superiority of TACE over TAE has not been consistently shown in the literature., Aim: To compare the outcomes of TACE and TAE in patients with HCC awaiting LT., Methods: All consecutive patients with HCC awaiting LT between 2011 and 2020 at a single center were included. All patients underwent LRT with either TACE or TAE. Some patients also underwent percutaneous ethanol injection (PEI), concomitantly or in different treatment sessions. The choice of LRT for each HCC nodule was determined by a multidisciplinary consensus. The primary outcome was waitlist dropout due to tumor progression, and the secondary outcome was the occurrence of adverse events. In the subset of patients who underwent LT, complete pathological response and post-transplant recurrence-free survival were also assessed., Results: Twelve (18.5%) patients in the TACE group (only TACE and TACE + PEI; n = 65) and 3 (7.9%) patients in the TAE group (only TAE and TAE + PEI; n = 38) dropped out of the waitlist due to tumor progression ( P log-rank test = 0.29). Adverse events occurred in 8 (12.3%) and 2 (5.3%) patients in the TACE and TAE groups, respectively ( P = 0.316). Forty-eight (73.8%) of the 65 patients in the TACE group and 29 (76.3%) of the 38 patients in the TAE group underwent LT ( P = 0.818). Among these patients, complete pathological response was detected in 7 (14.6%) and 9 (31%) patients in the TACE and TAE groups, respectively ( P = 0.145). Post-LT, HCC recurred in 9 (18.8%) and 4 (13.8%) patients in the TACE and TAE groups, respectively ( P = 0.756). Posttransplant recurrence-free survival was similar between the groups ( P log-rank test = 0.71)., Conclusion: Dropout rates and posttransplant recurrence-free survival of TAE were similar to those of TACE in patients with HCC. Our study reinforces the hypothesis that TACE is not superior to TAE as a bridging therapy to LT in patients with HCC., Competing Interests: Conflict-of-interest statement: All authors declare no conflict of interest., (©The Author(s) 2024.
