When resecting small tumors or tumors with an irregular margin, a marking technique is conducted prior to the surgery. CT-guided marking techniques are common in pulmonary surgery, but it is rarely used in abdominal or urological surgery. We performed a marking technique for a small tumor that was undetectable by ultrasound using CT guidance prior to laparoscopic resection.A 63 year-old woman, two years after total hysterectomy for uterine stromal sarcoma, underwent combined right kidney resection and retroperitoneal tumor resection for a giant recurrence. Two months after the surgery, micro recurrence was observed in the vicinity of the right intestinal psoas muscle which upon follow up, the tumor size increased to 1 cm. Surgical resection of the small recurrent tumor was planned. Since it was difficult to detect by ultrasound, preoperative CT-guided marking was performed. Retroperitoneal laparoscopic resection was performed the following day. The histopathological diagnosis was endometrial stromal sarcoma.

: Computed tomography (CT)-guided transbronchial metallic coil marking is useful for identifying the locations of small peripheral pulmonary lesions. Even deeply located lesions may be accurately identified and resected with adequate margins. This method is also applicable to multiple lesions.

Background: Accurate preoperative localization is a challenge in thoracoscopic surgery for multiple pulmonary nodules. In this study, we aimed to assess the accuracy and feasibility of electromagnetic navigation (EN)-guided percutaneous localization.
Methods: We enrolled 50 patients with multiple pulmonary nodules for EN-guided (EN group) or CT-guided (CT group) localization.

Background: Preoperative computed tomography (CT)-guided localization of small pulmonary nodules (SPNs) is the major approach for accurate intraoperative visualization in video-assisted thoracoscopic surgery (VATS). However, this interventional procedure has certain risks and may challenge to less experienced junior doctors. This study aims to evaluate the feasibility and efficacy of robotic-assisted CT-guided preoperative pulmonary nodules localization with the modified hook-wire needles before VATS.

Background And Objective: Subpleural located pulmonary nodules are perioperatively invisible to the surgeon. Their precise identification is conventionally possible by palpation, but often at the cost of performing a thoracotomy. The aim of the study was to evaluate the success rate and feasibility of the pre-operative CT-guided marking subpleural localized nodule using a mixture of Patent Blue V and an iodine contrast agent prior to the extra-anatomical video-assisted thoracoscopic surgery (VATS) resection in patients for whom the primary anatomical resection in terms of segmentectomy or lobectomy was not indicated.

Lymphadenectomy represents a fundamental step in the staging and treatment of non-small cell lung cancer (NSCLC). To date, the extension of lymphadenectomy in early-stage NSCLC is a debated topic due to its possible complications. The detection of sentinel lymph nodes (SLNs) is a strategy that can improve the selection of patients in which a more extended lymphadenectomy is necessary.
