Objective To test the feasibility of a novel contrast-enhanced ultrasound (CEUS) technique, or lymphosonography, for sentinel node biopsy (SNB) of the supraglottis in a porcine model. Study Design and Setting In this prospective, non-randomized animal study, blue dye and ultrasound contrast agent were injected into the supraglottis in seven 50-kg Yorkshire swine. Transcutaneous CEUS was used to identify real-time lymphatic flow of contrast through lymph channels (LC) to the sentinel lymph node (SLN). SNB was carried out, visually identifying a blue node, with the assistance of intraoperative CEUS. Bilateral modified radical neck dissections were performed to search for any residual contrast-positive or blue SLNs. Results In each case, at least one SLN was identified by preoperative CEUS. A total of 12 nodes were identified on preoperative CEUS, and 11 of 12 nodes were stained with blue dye (91.7%). No residual blue or contrast-positive nodes were identified on neck dissection. Conclusions Lymphosonographic SNB of the supraglottis in a porcine model is technically feasible, and yields results comparable to traditional blue dye–guided techniques. No “shine-through” effect or nonsequential nodal enhancement occurred. This technique holds promise for sentinel node biopsy and allows a novel method for in vivo investigation of the lymphatic system.

Objectives: We evaluated lymphosonography, or contrast-enhanced, ultrasonography (US)–guided sentinel lymph node (SLN) detection, as a technique for demonstrating the lymphatic drainage of the thyroid gland. Methods: In this prospective animal study, four 50-kg Yorkshire swine underwent transcutaneous injection of a US contrast agent and methylene blue dye into the thyroid gland. Contrast-enhanced US was used to identify draining lymphatic channels and SLNs. Sentinel node biopsy was conducted. Subsequently, bilateral neck and upper mediastinal dissection was carried out. Results: In 3 of 4 cases, a blue dye–positive and US contrast–positive SLN was identified. We identified SLNs in level IV in 2 cases. One case revealed 2 adjacent nodes in the superior mediastinum. In 1 case, a lymphatic channel was identified traveling into the mediastinum, but exposure of the SLN could not be obtained. No residual blue dye–positive or US contrast–positive nodes were identified on subsequent dissection. Conclusions: Lymphosonography of the thyroid gland in a porcine model correlates well with blue dye–guided sentinel node biopsy and is technically feasible, although in some cases access to the SLN may be difficult. This technique could potentially enable a detailed analysis of thyroidal lymphatic drainage if applied to humans.

e19002 Background: Sentinel node biopsy (SNB) is used in the management of melanoma patients without nodal metastases. Methods: From January 1, 1998 to December 31, 2011 we performed 182 SNBs at St. M. Goretti Hospital. Patients presented a primary melanoma, Breslow thickness equal to or higher than 1 mm, lower than 1 mm with regression and/or ulceration, and/or IV-V Clark level, and/or mitotic rate ≥ 1/mm2, according to the 7th edition melanoma staging system. All patients underwent pre-operative lymphoscintigraphy with intradermal injection of 50-70 MBq 99 mTc colloidal albumina particles, 50-80 nm size range, in 0.1-0.2 ml saline solution. We never used blue dye. All patients underwent surgical treatment 4-12 h. later. We performed SNB in day-surgery (DS) under local anaesthesia (LA). Surgery incision was 3-4 cm. This study was approved by an ethics committee, discussed with all patients and informed consent was obtained. Purpose of the study is to investigate the validity of this approach for quality of life and cost reduction. Results: 165 patients underwent SNB, 64 (38.7%) in the inguinal region, 83 (50.3%) in axilla, 1 (0.6%) in the popliteal region, 4 (2.4%) patients showed inguinal bilateral sentinel lymph-node (SLN), 6 (3.6%) axillary bilateral SLN, 4 (2.4%) axillary and 3 (1.8%) inguinal double SLN. The SLN identification rate was 100%. After surgery we distributed a questionnaire to the patients about the acceptability of this approach. In 32 patients SLN was positive. In these patients we performed radical lymphoadenectomy, 12 (37.5%) inguinal and 20 (62.5%) axillary. Conclusions: The results achieved are extremely accurate. This procedure is safe, well accepted by patients (98%), reported better quality of life. The oncological results are absolutely reliable. As regards hospital logistics, operations in DS and LA can be easily managed, leading to a significant cost reduction, 42.15% less expensive than the same operation performed under general anaesthesia.
