“…There is no clear evidence supporting superiority of multiday regimens over single-dose treatments (38,39). Other situations in which the use of antibiotic agents may be considered include biopsies performed via a transvaginal or transoral approach, biopsies involving needle transgression of bowel loops, biopsies of potentially infected target lesions, and biopsies in immunocompromised patients (40)(41)(42); however, there is no documented evidence showing that the use of antibiotic agents in these situations reduces the risk of infection.…”

“…The data in the literature are mostly retrospective. Some studies included patients with non-specified abdominal-pelvic tumors who were often previously considered unsuitable for surgery 10 19–24. Therefore, correlation between ultrasound-guided tru-cut biopsy and final surgical histology is rarely reported 10 24.…”

“…In the field of gynecologic oncology, some studies have investigated the role of ultrasound-guided biopsy in the management of abdominal and pelvic tumors, demonstrating that the procedure is safe and feasible 10 19–25. However, most were retrospective studies and included patients with different tumor sites (cervical cancer, ovarian cancer, and endometrial cancer).…”

ObjectiveTo assess the accuracy of pathological diagnosis by transvaginal ultrasound-guided biopsy versus surgery in patients with suspicious primary advanced tubo-ovarian carcinoma. The Feasibility, adequacy, and safety of the procedure were also evaluated.MethodsConsecutive women with pre-operative suspicious primary advanced tubo-ovarian carcinoma presenting between July 2019 and September 2021 were enrolled. Accuracy was calculated including only cases who underwent surgery. Feasibility was defined as the number of cases in which ultrasound-guided biopsy was possible according to tumor characteristics (morphology and site). Adequacy was defined as the number of conclusive diagnoses out of the samples collected. Safety was defined by the number of major complications which were defined as hospitalization, surgery, and/or blood transfusion.ResultsA total of 278 patients were eligible for the study; 158 were enrolled, while 120 were excluded for logistic reasons or patient refusal. Ultrasound-guided biopsy was not feasible in 30 (19%) patients. The samples obtained in the remaining 128 patients were all adequate (100%), and no major complications were noted. A total of 26 (20%) patients started neoadjuvant chemotherapy on the basis of the diagnosis obtained by ultrasound, whereas 102 (80%) patients underwent surgery. Accuracy of ultrasound-guided biopsy versus surgery was 94% (96/102), with six false negative cases at ultrasound (6%). Site (prevesical peritoneum) and size (<8 mm) of the nodules resulted as major predictive factors for ultrasound-guided biopsy failure (false negative). Ultrasound-guided biopsy correctly identified 86 primary invasive tubo-ovarian carcinomas and 10 metastatic tumors.ConclusionUltrasound-guided biopsy is a feasible, safe, and accurate method to provide histological diagnosis in suspicious advanced tubo-ovarian cancer patients.

“…Ultrasound-guided and CT-guided core biopsies are both well-established, minimally invasive methods capable of providing good quality specimens for histological diagnosis. However, the transvaginal route may provide an easier exposure to lesions situated deeply in the pelvic cul-de-sac or the gynaecological organs [ 5 , 10 , 12 , 14 , 18 , 19 ]. CT-guided procedures are more expensive and their availability is limited in our country; therefore, ultrasound-guided biopsies may accelerate the diagnostic process compared to CT-guided biopsies.…”

“…Ultrasound-guided biopsy is a routine diagnostic method to obtain tissue samples and used widely in different types of tumours [ 1 , 2 , 3 ]. Pelvic solid masses can be biopsied via transabdominal, transvaginal, transrectal or transperineal routes [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Generally, lesions located deep within the female pelvis are not easy to access transdabdominally due to various bowel loops, major vessels, uterus, urinary bladder and ureter being in the path of the needle [ 1 , 11 , 12 ].…”

In this paper, we report our experience of transvaginal ultrasound (TVUS)-guided core biopsies involving 303 patients referred to the gynaecological ultrasound unit of our national comprehensive cancer centre. Adequate histologic specimens were obtained in 299 patients (98.7%). The most common sites of biopsy sampling were the adnexa (29.7%), the vaginal stump or wall (13.5%), the uterus (11.6%) and the peritoneum (10.2%). Malignancy was confirmed in two-thirds of patients (201/303) and a primary malignancy was diagnosed in 111 of the 201 histologically verified malignant cases (55.2%). Interestingly, 23.9% (48/201) of malignant tumours were proven to have a non-gynaecological origin. Among them, gastrointestinal tumours occurred the most frequently (31/48 patients). Three abscesses were discovered following the biopsy procedure, resulting in a complication rate of 1%. In 94 (31%) patients, subsequent surgery allowed the comparison of the ultrasound-guided and surgically obtained histologic results. We found inaccuracy in 12 cases (12.8%), which is discussed in this paper in detail. Sensitivity, specificity, PPV and NPV to diagnose malignancy was 94.8%, 94.1%, 98.7% and 80.0%, respectively. This is the largest study reported to date about the efficacy and safety of TVUS-guided core biopsy in evaluating pelvic lesions giving rise to a suspicion of gynaecological cancer.

Transrectal or transvaginal ultrasoundguided biopsy for pelvic masses: external validation and usefulness in oncologic patients

Abstract: This study externally validated the feasibility and safety of TRUS- or TVUS-guided biopsy. In addition, these techniques appear to enable accurate pathologic diagnoses of pelvic masses in oncologic patients to be made safely and relatively noninvasively.
