Foreign bodies (FBs) retained in the subcutaneous tissues are a common reason for medical consultation. In small animals, FBs usually consist of vegetal materials, especially grass awns. Failure to remove the FBs is likely to give rise to acute or late complications. The surgical removal of the FBs can be invasive, costly and technically challenging. Ultrasound has become a mainstay in the detection of FBs and it can be used to guide the extraction of the FBs with a minimally invasive technique. This study describes the detection and extraction of soft-tissue FBs in small animals. One hundred-sixty-two patients, presenting at two veterinary clinics with suspected FBs retained in the soft tissues of various body districts, were considered. Once an ultrasound diagnosis was established, the ultrasound-guided removal of the FB was performed. A high-frequency linear transducer, a skin disinfection, sedation or anaesthesia was used when needed and a scalpel and some Hartmann forceps were also used. One hundred-eighty-two FBs were successfully removed in all the patients. In six cases, the FB was identified during a second ultrasonographic examination, after recurrence of the fistula. No complications were reported after the procedure. The extraction of the FB was performed in an echographic suite in 138 cases and in a surgery room with surgical intervention in 24 cases. In the latter situation, the surgical minimally invasive dissection of tissues under ultrasound guidance was performed before the removal of the FB. In conclusion, the ultrasound-guided removal of the FBs retained in the superficial soft tissue can be considered a good alternative to surgery. However, failure to remove a FB does not preclude the removal by traditional surgery.

Abstract Background and study aims Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) with a lumen-apposing metal stent (LAMS) is a novel, minimally invasive technique in the palliative treatment of malignant gastric outlet obstruction (GOO). Several studies have demonstrated feasibility and safety of EUS-GE, but evidence on long-term durability is limited. The aim of this study was to evaluate patency of EUS-GE in treatment of malignant GOO. Patients and Methods An international multicenter study was performed in seven centers in four European countries. Patients who underwent EUS-GE with a LAMS between March 2015 and March 2019 for palliative treatment of symptomatic malignant GOO were included retrospectively. Our main outcome was recurrent obstruction due to LAMS dysfunction; other outcomes of interest were technical success, clinical success, adverse events (AEs), and survival. Results A total of 45 patients (mean age 69.9 ± 12.3 years and 48.9 % male) were included. Median duration of follow-up was 59 days (interquartile range [IQR] 41–128). Recurrent obstruction occurred in two patients (6.1 %), after 33 and 283 days of follow-up. Technical success was achieved in 39 patients (86.7 %). Clinical success was achieved in 33 patients (73.3 %). AEs occurred in 12 patients (26.7 %), of which five were fatal. Median overall survival was 57 days (IQR 32–114). Conclusions EUS-GE showed a low rate of recurrent obstruction. The relatively high number of fatal AEs underscores the importance of careful implementation of EUS-GE in clinical practice.

Abstract ObjectiveMicrowave ablation (MWA) is a minimally invasive technique for the treatment of benign thyroid nodules. The purpose of this study was to evaluate the efficacy and safety of ultrasound-guided microwave ablation in the treatment of benign thyroid nodules, and to provide reference for future clinical work.MethodsThis study retrospectively analyzed the patients who received ultrasound-guided microwave ablation for benign thyroid nodules in our hospital from October 2018 to March 2020. A total of 214 patients were included in the study. We assessed thyroid volume changes (represented by volume reduction ratio VRR) , the serum levels of triiodide thyroid hormone (T3), thyroxine (T4) and thyrotropin (TSH) and complications after MWA treatment.ResultsThere were a total of 306 nodules in 214 patients, including 183 (85.51%) females and 31 (14.49%) males. The median diameter and volume of the nodule were 33mm and 8.01ml. The volume reduction ratio（VRR）at 1 month, 3 months, 6 months and 12 months were 40.79%, 60.37%, 74.59% and 85.60%, respectively.（P<0.05) In addition, initial nodular volume were the influencing factors of volume reduction ratio.ConclusionsUltrasound-guided MWA is effective and safe in the treatment of benign thyroid nodules. In addition, it has little damage to surrounding tissues and no effect on thyroid function. Especially for the initial small volume of nodules, treatment is better. Therefore, ultrasound-guided thyroid MWA can be used as one of the main clinical treatment methods for benign thyroid nodules.

The evaluation of mediastinal lymph nodes is critical for the correct staging of patients with lung cancer (LC). Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique for mediastinal staging, though unfortunately lymph node micrometastasis is often missed by cytological analysis. The aim of this study was to evaluate the predictive capacity of methylation biomarkers and provide a classification rule for predicting malignancy in false negative EBUS-TBNA samples. The study included 112 patients with a new or suspected diagnosis of LC that were referred to EBUS-TBNA. Methylation of p16/INK4a, MGMT, SHOX2, E-cadherin, DLEC1, and RASSF1A was quantified by nested methylation-specific qPCR in 218 EBUS-TBNA lymph node samples. Cross-validated linear regression models were evaluated to predict malignancy. According to EBUS-TBNA and final diagnosis, 90 samples were true positives for malignancy, 110 were true negatives, and 18 were false negatives. MGMT, SHOX2, and E-cadherin were the methylation markers that better predicted malignancy. The model including sex, age, short axis diameter and standard uptake value of adenopathy, and SHOX2 showed 82.7% cross-validated sensitivity and 82.4% specificity for the detection of malignant lymphadenopathies among negative cytology samples. Our results suggest that the predictive model approach proposed can complement EBUS-TBNA for mediastinal staging.

Objective: To report our technique for percutaneous ultrasound-guided retrieval of accidentally transected arterial lines. Cases description: Two patients are reported herein; in both of these patients, a part of the 20-gauge catheter inserted for invasive monitoring of their blood pressure in the intensive care unit was accidentally transected with part of the catheter remaining in the radial artery. Both patients were initially asymptomatic; therefore, a minimally invasive technique was sought to remove the catheters without inducing significant risk. Under local anesthesia and ultrasound guidance at the patient bedside, a 6Fr slender sheath was introduced and with the help of a Fogarty catheter in one case, and in the other case, a 0.014-in hydrophobic wire was used to cannulate the catheter, and it was withdrawn into the sheath and removed with it uneventfully.

Background: Endoscopic ultrasound-guided transbronchial fine-needle aspiration (EBUS-TFNA) is a minimally invasive technique for diagnosis of mediastinal masses/lesions. Although most studies have reported the utility of EBUS-TFNA in malignancy, its use has been extended to the benign conditions as well. Objective: The present study focused on utility of EBUS in contributing to reach the final diagnosis of sarcoidosis. Design: From May 2010 to December 2013, 19 of 80 patients who underwent EBUS-TFNA at one center for radiologically suspicious lesions for sarcoidosis, and with no definite histological diagnosis, were included in this retrospective study. Results: When the histological diagnosis was taken as the gold standard, the sensitivity of EBUS-TFNA was 84.2% and specificity 100% with the positive predictive value of 100. The combined diagnostic sensitivity of EBUS-TFNA and transbronchial lung biopsy was 100%. Conclusion: EBUS is a valuable, minimally invasive diagnostic modality to support the diagnosis of sarcoidosis in appropriate clinical setting, after conventional work-up – particularly if patients have suspicious radiological findings. This minimally invasive procedure helps in providing a final diagnosis without exposing the patient to the risk of complications from more invasive procedures.
