Filter by:Context: Adrenalectomy for pheochromocytoma (PHEO) poses difficulties due to the elevated chance of conversion. The objective of this study was to conduct a comparative analysis of the occurrence and determinants of conversion in left-sided abdominal laparoscopic adrenalectomy (LLA) and right-sided abdominal laparoscopic adrenalectomy (RLA). Methods: A retrospective analysis was conducted to include a total of 271 patients diagnosed with PHEO. These patients were separated into two groups: LRA (N=121) and LLA (N=150). The study period spanned from September 2016 to September 2023.
One-arm clinical trial was adopted in this study. The surgeon performed remote urological surgery for patients through domestically produced "MicroHand" surgical robot system (Shandong Weigao Co., Ltd). The "MicroHand" surgical robot system consists of two physically separated subsystems named the "surgeon console" and "patient side cart". The surgeon console includes a stereo image viewer, two master manipulators, a control panel and several foot pedals. The patient side cart includes a passive arm that can slide in the up-down direction and be adjusted forward and backward, a swivel head that can rotate around the vertical axis, and three slave arms (one for the endoscopic camera and the other two for surgical instruments). The surgeon console (based in Qingdao) takes the surgeon's input and translates manipulation into a control signal. After network transmission, the patient side cart (based in other cities in Shandong Province) translates the control signal into actual instrument manipulation. The 3D images captured by the endoscopic camera were simultaneously sent back to the screen of the surgeon console as visual feedback. Data between the surgeon console and the patient side cart were transmitted through a 5G network. The safety and effectiveness of the robotic system in remote clinical diagnosis and treatment were verified by the main judgment criterion and secondary judgment criterion. Fifty patients with urinary diseases are planned to enroll in the clinical trial. Main judgment criterion: The robot-assisted telesurgery did not transfer to other types of surgery, such as open surgery or normal robot-assisted surgery. Secondary judgment criterion: operative time, blood loss, postoperative pain, preoperative adjusting time and hospitalization time. Patient enrollment: This trial aims to explore the safety and effectiveness of the domestically produced robotic system in remote clinical diagnosis and treatment through 5G network. Fifty patients with urinary diseases are planned to enroll in the clinical trial.

Patient enrollment: This trial aims to explore the safety and effectiveness of the domestically produced robotic system in remote clinical diagnosis and treatment through 5G network. Six patients are planned to enroll in the clinical trial, including 2 patients with adrenal tumor, 2 patients with bladder cancer and 2 patients with renal cell carcinoma.
With our retrospective study the investigators show the limitations of the posterior retroperitoneal adrenalectomy by analyzing anatomical parameters. The investigators compared the data from one patient who underwent a conversion with 13 patients without a conversion. Furthermore, they explored the influence of these parameters on the operation time and excluded the patient who had a conversion from this analysis. The investigators hypothesize that by determining anatomical characteristics on cross-sectional imaging (CT or MRI), they can show the limitations of the posterior retroperitoneal adrenalectomy to prevent patients from being converted to lateral transperitoneal adrenalectomy.
Laparoscopic adrenalectomy is the treatment of choice for the benign tumor of less than 6 cm. However, this is an ongoing debate that exact cut-off value of tumor size for LA. The aim of this study was to assess whether the size of the adrenal tumor affects preoperative and postoperative outcomes in patients undergoing laparoscopic transperitoneal adrenalectomy as well as to evaluate the learning curve.
Benign complex cystic and vascular adrenal tumors comprise a group of lesions characterized by significant rarity. But, their detection is increasing due to improved radiologic imaging techniques. Nevertheless, they are still conflicting with other lesions. the investigators reviewed their experience with complex cystic benign adrenal tumors in adults, review previous reports to determine the appropriate diagnosis and management of these tumors.
Tumors are characterized by a great heterogeneity. Characterizing this intra-tumor heterogeneity is a major challenge in oncology to improve the therapeutic management and move towards personalized medicine adapted to each patient. However, intra-tumor heterogeneity remains rarely used for diagnostic purposes The discovery of an adrenal mass can occur in different circumstances. Detection of an adrenal mass can be done in a context of secreting syndrome, in the assessment of an extra-adrenal neoplasia or fortuitously when performing an imaging for another reason. The etiologies are numerous (cortical tumors, medullary tumors, metastatic lesion of a extra-adrenal neoplasia, others). The adrenal masses can be divided into two categories, depending on whether they are hyperfunctional or not. In patients without an oncological history, an adrenal mass discovered is most often a benign adenoma, but requires an endocrine assessment. In patients with known primary cancer, approximately 30% of the adrenal masses are malignant. In all cases, the diagnostic procedure includes an imaging assessment to characterize the lesion and an endocrine assessment. CT scan performed without and after intravenous iodinated contrast agent injection is the first-line examination to assess an adrenal mass. 18F-FDG-PET may be indicated as second-line for characterizing an adrenal mass. Adrenal tumor SUVmax (Standard Uptake Value) and adrenal tumor SUVmax / liver SUVmax ratio are routinely used to determine the malignancy of a lesion. Although very useful for assessing the glucose metabolism of a given lesion, these parameters do not allow assessing the heterogeneity of tumor uptake. The texture analysis corresponds to an analysis of the spatial distribution of FDG uptake, and allows, by the calculation of many indices, an evaluation of the heterogeneity of the tumors. The hypothesis of our study is that the texture parameters could have an additional diagnostic value to improve the performance of conventional quantitative parameters to determine the malignancy of a lesion. The objective of this study is to investigate the diagnostic value of texture indices in a large cohort of patients presenting an adrenal lesion
To analyze the diagnostic performance, safety, impact on clinical management, predictors of malignancy and cyto-pathological correlation of the EUS-FNA with AG. National multicenter retrospective study. Mailing-SEED partners. Participation: 17 Spanish centers. Inclusion period: April / 2003 to April / 2016 Inclusion criteria: All AG (Left / Right) punctured by EUS. A review of 205 EUS-FNA of AG in 200 patients is included.
Laparoscopic adrenalectomy has become the gold standard operation for non-malignant adrenal tumors replacing open adrenalectomy. The most popular lateral transperitoneal laparoscopic adrenalectomy (LTLA) approach has been recently challenged by an increasing popularity of the posterior retroperitoneoscopic adrenalectomy (PRA) approach which is believed by many surgeons as an easy to learn, reproducible and beneficial for patients. However, this belief is not evidence-based, so far. The aim of this study is to clarify if PRA is superior to the LTLA as minimally invasive approach to small and benign adrenal tumors.
The improvement of conventional imaging techniques has led to an increased detection rate of different adrenal tumors. Since those tumors can belong to a variety of entities the therapeutic consequences also show considerable variation. In order to definitely determine the type of tumor, invasive procedures like CT guided biopsies are often required, which could be avoided by a tumor specific imaging method. The presently available scintigraphic procedures are either time consuming and lead to high radiation exposure or are technically demanding. The steroidogenic enzymes CYP11B1 (11ß-hydroxylase)and CYP11B2 (aldosterone synthase)are expressed exclusively in the adrenal cortex and therefore represent suitable targets for a specific imaging technique. In our project we evaluate 123I-Iodometomidate which binds to both CYP11B enzymes as radiotracer for adrenal scintigraphy.
