Since April 1983, harpoon technique was used for limited excision of subclinical mammography-observed anomalies. The procedure involves the insertion of a harpoon-shaped metallic thread, after detection by mammography, to obtain guidance of surgical procedures. The results of 155 procedures in 149 patients included detection of 38 cancers (26%), confirming documented data in this field.

Aim: Colorectal cancer (CRC) primarily arises from a combination of genetic, environmental, and dietary factors. Compared to traditional open surgery, minimally invasive laparoscopic surgery offers several advantages in managing CRC. This study investigates the factors influencing dynamic intestinal obstruction following laparoscopic colorectal radical surgery.

Background: Surgery is the preferred treatment for primary hyperparathyroidism. Minimally invasive parathyroidectomy is only feasible with accurate preoperative localisation. Virtual 3D anatomical models can be constructed from patient-specific CT scans using segmentation software.

Background: Targeted and systematic transperineal biopsy of lesions guided by magnetic resonance imaging (MRI) and transrectal ultrasonography (TRUS) fusion technique may optimize the biopsy procedure and enhance the detection of prostate cancer. We described the transperineal biopsy guided by an automatic MRI-TRUS fusion technique, and evaluated the accuracy and feasibility of this method in a prospective single-center study.
Methods: The proposed method focuses on automating the delineation of prostate contours in both the MRI and TRUS images, the registration and fusion of MRI and TRUS images, the generation and visualiztion of the systematic biopsy cores in their corresponding locations within the 2D and the 3D views, as well as the computation and visualiztion of needle trajectories from preoperative planning to intraoperative navigation.

Rationale And Objectives: To improve the diagnostic recognition of papillary renal neoplasm with reverse polarity (PRNRP) through comprehensive analysis of computed tomography (CT) and magnetic resonance imaging (MRI) findings.
Materials And Methods: A retrospective multi-center study was conducted on patients with pathologically confirmed PRNRPs from 2019 to 2024, encompassing six institutions. Clinical and pathological data were meticulously documented.

We report a case in which a giant hepatic cyst located at the hepatic hilum and compressing the inferior vena cava was safely treated laparoscopically with careful attention to hemodynamics in a difficult fenestrated resection in a patient with severe kyphosis. The anatomic location of the cyst was evaluated preoperatively via 3D reconstruction of computed tomography images to identify a site where safe fenestrated resection could be performed. This was challenging because the surgical field was narrow due to the presence of severe kyphosis, and there was a risk of damage to surrounding organs during fenestrated resection.
